application/pdf, ラオスでは，村落の住民が共同で利用できる，村落共有林の利用権が法的に認可されている。本稿は，この村落共有林をコモンズとして捉え，そのガバナンスの持続性について考察する。既存のコモンズ研究から明らかにされているように，コモンズのガバナンスが機能するためには，コミュニティ内に形成された社会関係資本がフリーライダーの発生を抑制するように働いていなければならない。そこで，本研究では，ビエンチャン特別市サントン郡の三村落を対象に，アンケート調査から，社会関係資本と住民の参加の関係性を明らかにした。その結果，村落ごとに差異はあるものの，村落内の社会関係資本（信頼とネットワ ーク）が住民の管理活動への参加を促す要因として機能していることが明らかになった。

Many technology adoption decisions are made under uncertainty about the costs or benefits of subsequent investments in the technology after the initial take-up. As new information is realized, agents may prefer to abandon a technology that appeared profitable at the time of take-up. Low rates of follow-through (engagement in subsequent investments) are particularly problematic when subsidies are used to increase adoption, in part because they may attract users with a lower value for the technology. We use a field experiment with two stages of randomization to generate exogenous variation in the payoffs associated with taking up and following through with a new technology: a tree species that provides private fertilizer benefits to adopting farmers. Our empirical results show high rates of abandoning the technology, even after paying a positive price to take it up. The experimental variation offers a novel source of identification for a structural model of intertemporal decision making under uncertainty. Estimation results indicate that the farmers experience idiosyncratic shocks to net payoffs after take-up, which increase take-up but lower average per farmer tree survival. We simulate counterfactual outcomes under different levels of uncertainty and observe that subsidizing take-up of the technology affects the composition of adopters only when the level of uncertainty is relatively low. Thus, uncertainty provides an additional explanation for why many subsidized technologies may not be utilized even when take-up is high.

This paper quantifies the aggregate impact of communal land tenure ar- rangements that prevail in Sub-Saharan Africa. Such tenure regimes limit land transfer- ability by prohibiting sales, subjecting rented-out land to the risk of expropriation, and redistributing it to existing farmers in a progressive fashion. We use a general equilibrium two-sector selection model featuring agents heterogeneous in skills to compute the result- ing occupational and operational choices as well as land allocations. The quantification of the model is based on policies deduced from Ethiopia. In the Sub-Saharan African context we find that such policies substantially dampen nominal agricultural relative to non-agricultural productivity, by 25%. Real relative agricultural productivity, however, only falls by 4% since cross-sectoral terms of trade adjust strongly, with excess agricul- tural employment only amounting to some 1.5 percentage points. The loss in GDP is small, about 2%. That serves as a reminder that ostensibly highly distortionary policies need not have substantial bite when individuals strategically adjust to them and equilib- rium prices adapt. For example, the model predicts that at given prices 62% of farmers in an economy such as Ethiopia would leave farming if tenure were secured, casting land insecurity as a major obstacle. Yet only 9% would actually switch sectors after price adjustments are factored in.

Understanding the causes of the Industrial Revolution, namely the process of transition from a Malthusian equilibrium to modern economic growth, has been the subject of passionate debate. This paper contributes to insights into the process of industrialization and the demographic transition that followed. We present a model that proposes a mechanism behind the claim that landed elites had strong incentives to block education reforms. By applying the theory of interest groups to landownership, landowners could delay education. However, they could not prevent its introduction indefinitely since gains for the landed elites derived from education would at some moment surpass the costs associated with them. We also sustain that improvements in agricultural productivity prior to the Industrial Revolution may have induced a positive impact on the landowners’ decision to educate the population, which led to an earlier introduction of education reforms. The conclusions fit the patterns of the late boom of industrialization and demographic transition and help explain why some countries (e.g., Britain and The Netherlands) had accelerated education reforms and a faster process of industrialization than most continental countries. A theoretical model is presented, and numerical simulations are exhibited to illustrate our claims.

International audience; We develop a model of optimal land allocation in a developing economy that features three possible land uses: agriculture, primary and secondary forests. The distinction between those forest types reflects their different contributions in terms of public goods. In our model, reforestation is costly because it undermines land title security. Using the forest transition concept, we study long-term land-use change and explain important features of cumulative deforestation across countries. Our results shed light on the speed at which net deforestation ends, on the effect of tenure costs in this process, and on composition in steady state. We also present a policy analysis that emphasizes the critical role of institutional reforms addressing the costs of both deforestation and tenure in order to promote a transition. We find that focusing only on net forest losses can be misleading since late transitions may yield, upon given conditions, a higher level of environmental benefits.; Nous développons un modèle d'allocation optimale des terres dans une économie en développement qui présente trois utilisations possibles des terres : agriculture, forêts primaires et secondaires. La distinction entre ces types de forêts reflète leurs différentes contributions en termes de biens publics. Dans notre modèle, la reforestation est coûteuse car elle porte atteinte à la sécurité des titres fonciers. En utilisant le concept de transition forestière, nous étudions les changements d'utilisation des terres à long terme et expliquons les caractéristiques importantes de la déforestation cumulative entre les pays. Nos résultats mettent en lumière la vitesse à laquelle la déforestation nette prend fin, l'effet des coûts de tenure dans ce processus et la composition en régime permanent. Nous présentons également une analyse politique qui souligne le rôle essentiel des réformes institutionnelles portant sur les coûts de la déforestation et de la tenure afin de promouvoir une transition. Nous constatons que se concentrer uniquement sur les pertes forestières nettes peut être trompeur, car les transitions tardives peuvent produire, dans certaines conditions, un niveau plus élevé de bénéfices environnementaux.

In this paper we explore whether low rates of sustained technology use can be explained by heterogeneity in returns to adoption. To do so we evaluate impacts of the Cocoa Abrabopa Association , which provided a package of fertilizer and other inputs on credit to cocoa farmers in Ghana. High estimated average productive impacts for treated farmers are found to be consistent with negative economic profits for a substantial proportion of the treated population. By constructing an individual specific measure of returns, we demonstrate that low realized returns among adopters are associated with low retention rates, even after conditioning on output levels and successful repayment. The results are consistent with the hypothesis that high average returns mask substantial and persistent heterogeneity, and that farmers experiment in order to learn about their idiosyncratic returns.

While political instability is broadly believed to be bad for economic growth., firm performance and foreign direct investment, few studies convincingly identify the causal impact of conflict on firms and export performance. In this paper, we analyze the impact of the Kenyan post-election violence on a hugely successful export oriented industry, the Kenyan flower industry,. Using export information on all Kenyan grower-exporters, we show that the conflict reduced Kenyan flowere exports by 24% overall. To account for demand shocks in the export markets, we then exploit the cross-regional variation in the post-election violence to identify the effect of the conflict on firms export volumes. We find that the conflict reduced exports by 23% for firms located in conflict areas, mainly through displacing workers. The displacement of semi-skilled workers is also shown to have had impacts substantially beyond the duration of the conflict. While there is no evidence to suggest that the conflict affected export volumes in the areas without conflict, we find evidence that it did change exporters behaviour. Shipments were consolidated and exported less frequently, while security expenses rose. This suggests that exporters in non-conflict areas reacted to the increased insecurity by transporting larger, more secured shipments to the airport less frequently.

Surprisingly little is known about the impact resource booms on income inequality in resource rich countries (Ross, 2007). This paper develops a simple theory, in the context of a two sector growth model in which learning-by-doing drives growth, to explain the time path of inequality following a resource boom. Under plausible conditions, we find that income inequality will fall in the short run immediately after a boom, and will then increase steadily over time as the economy grows, until the initial impact of the boom on inequality disappears. Using panel co-integration methodology for a sample of 90 countries between 1965 and 1999, we test the predictions of the model empirically. We find strong evidence in support of the theory. Resource booms, especially mineral booms, lower inequality in the year of the boom. This effect then gradually diminishes over time until inequality returns to its pre-boom level in the long run.

The paper studies the long-run effects of shocks to resource rents on the economy using a structural vector error correction model for 37 developing countries. First, the long-run relations involving resource rents and the economy differ for resource importers and exporters. Second, there is an indirect effect from resource rents to output through public capital accumulation for resource exporters. third, although resource rents have a positive long-run impact on output, good public investment management is required for resource rents to improve non-resource output.

Do local populations benefit from resource booms? How strong are market linkages between the mining sector and the regional economy? This paper exploits exogenous variation in mine-level production volumes generated by the recent copper boom in Zambia to shed light on these questions. Using a novel dataset, I find robust evidence that an increase in local copper production improves living standards in the surroundings of the mines even for households not directy employed in the mining sector: a 10% increase in constituency-level copper output is associated with a 2% increase in real household expenditure; positive effects on housing conditions, consumer durable ownership and child health are of similar magnitude. The positive spill-overs extend to the rural hinterland of mining cities, neighboring constituencies, and constituencies to the copper transportation route. Additionally,I identify boom-induced changes in the demand for servics and agricultural products as key channels through which the urban and rural populations benefit from the mine expansions. Since the boom failed to generate fiscal revenues, these effects can be interpreted as the result of the mines' backward linkages. Taken together, these findings highlight the welfare potential of local procurement policies in resource rich developing countries.

Organic farming is often presented as the success story of Rural Development policies in the European Union, having grown from a marginal activity to one covering more than 5% of European agricultural land. Even though organic farming is often thought of as small-scale farming, I show that organic farms in Europe display characteristics associated with capitalist agriculture. Organic farms are larger and more mechanized than conventional farms. Furthermore, organic farms are associated with wage-labor and use less labor per hectare than their conventional counterparts, casting doubt on the efficacy of organic farming in increasing labor demand in marginalized communities and acting as an effective tool for keeping rural residents in the countryside. These results present us with evidence of the “conventionalization†of organic farming, and with a significant case of “green-washing†of capitalist structures of production.

In many developing countries including Nepal, water fetching is traditionally conducted by women and girls. In a mountainous hinterland of Nepal without systematic water and electricity supply, it is inevitably laborious, and as a result, girls receive fewer educational opportunities than boys. This paper aims to identify the causal effect of household water accessibility on children’s educational attainment measured by school attendance, grade repetition, and completion of primary and lower secondary schools in remote mountainous villages in Nepal. The estimation results evince that water hauling hinders girls from completing schooling, indicating that a one-hour increase in the time spent going to and from the water source will decrease the probability of female children completing primary school by 24.1 percentage points, while male children do not drop out, although they are more likely to repeat a grade. This implies that increased water accessibility—for example, by providing a solar water pumping system that the Nepali government promotes—improves household wellbeing, particularly girls’ educational attainment, by reducing the burden of water collection., This work was supported by JSPS KAKENHI (grant numbers JP25257102 and 16K21162).

Climate change is predicted to affect global rainfall patterns, but there is mixed evidence with regard to the effect of rainfall on civil conflict. Even among researchers who argue that rainfall reduces civil conflict, there is disagreement as to the underlying mechanism. Using data from the Philippines for the period 2001-2009, we exploit seasonal variation in the relationship between rainfall and agricultural production to explore the connection between rainfall and civil conflict. In the Philippines, above-average rainfall during the wet season is harmful to agricultural production, while above-average rainfall during the dry season is beneficial. We show that the relationship between rainfall and civil conflict also exhibits seasonality, but in the opposite direction and with a one-year lag. Consistent with the hypothesis that rebel groups gain strength after a bad harvest, there is evidence that lagged rainfall affects the number of violent incidents initiated by insurgents but not the number of incidents initiated by government forces. Our results suggest that policies aimed at mitigating the effect of climate change on agricultural production could weaken the link between climate change and civil conflict.

We evaluate causal impacts of a large‐scale agricultural extension program for smallholder women farmers on technology adoption and food security in Uganda through a regression discontinuity design that exploits an arbitrary distance‐to‐branch threshold for village program eligibility. We find eligible farmers used better basic cultivation methods, achieved improved food security. Given minimal changes in adoption of relatively expensive inputs, we attribute these gains to improved cultivation methods that require low upfront monetary investment. Farmers also modified their shock‐coping methods. These results highlight the role of information and training in boosting agricultural productivity among poor farmers and, indirectly, improving food security.

Building on the idea that members of religious communities insure each other against some idiosyncratic risks, we argue that religious communities should be more widespread where populations face greater common risk. Our theoretical argument builds on idiosyncratic and common risks aggravating each other. When this is the case, individuals have a greater incentive to mutually insure against idiosyncratic risk when greater common risk makes the worst case scenario of bad realizations of common and idiosyncratic risks more likely. Our empirical analysis exploits common rainfall risk as a source of common county-level agricultural risk in the 19th-century United States. We find that a greater share of the population was organized in religious communities in counties with greater common agricultural risk, holding expected agricultural output constant. The link between rainfall risk and membership in religious communities is stronger among more agricultural counties and counties exposed to greater rainfall risk during the growing season. We also find that among the historically more agricultural counties, more than 1/3 of 19th-century differences in religious membership associated with rainfall risk persist to the turn of the 21st century.

The prevalence of untitled land in poor countries helps explain the international agricultural productivity differences. Since untitled land cannot be traded across farmers, it creates land misallocation and distorts individuals' occupational choice between farming and working outside agriculture. I build a two-sector general equilibrium model to quantify the impact of untitled land. I find that economies with higher percentages of untitled land would have lower agricultural productivity; land titling can increase agricultural productivity by up to 82.5 percent. About 42 percent of this gain is due to eliminating land misallocation, and the remaining is due to eliminating distortions in individuals' occupational choice.

This paper studies the effect of oil discoveries on economic growth in Brazilian municipalities for the period from 1940 to 2000. It uses a unique identification strategy which exploits data on the drilling of approximately 20,000 oil wells in Brazil since oil explorations began in the country. We argue that oil discoveries are randomly assigned conditional on geological characteristics. The quasi-experimental outcome from drilling generates the treatment assignment: municipalities where oil was discovered during drilling constitute the treatment group while municipalities with drilling but no discovery are the control group. In our preferred specifications we find that oil discoveries increase per capita GDP by 25% over the 60-years period compared to the control group. Importantly, oil extraction has positive spillovers to other sectors of the economy. Services GDP per capita is estimated to increase by roughly 20% and urbanization by over 4% points. We show that the increase in services GDP per capita is mainly due to an increase in labor productivity. In line with intuition, these spillovers are present for onshore but not for offshore discoveries. Among other potential channels, the results are consistent with an increase in local demand for non-tradable services driven by the oil producing firm and highly paid oil workers.

Does the central bank practice of publishing interest rate projections (IRPs) improve how market participants map new information into future interest rates? Using high-frequent data on Forward Rate Agreements (FRAs) we compute market forecast errors; differences between expected future interest rates and ex post realizations. We assess their change in narrow windows around monetary policy announcements and macroeconomic releases in Norway and Sweden. Overall, communication of future policy plans do not improve markets' response to information, irrespective of whether or not IRPs are in place. A decomposition of market reactions into responses to the current monetary policy action ("target") and responses to signals about the future ("path"), reveals that only policy actions lead to improvements in market forecasts.

This research advances the hypothesis that natural land productivity in the past, and its effect on the desirable level of cooperation in the agricultural sector, had a persistent effect on the evolution of social capital, the process of industrialization and comparative economic development across the globe. Exploiting exogenous sources of variations in land productivity across (a) countries; (b) individuals within a country, (c) migrants of different ancestry within a country, and (d) individuals residing in regions within a country, the research establishes that lower level of land productivity in the past is associated with more intense cooperation and higher levels of contemporary social capital and development.

Contract farming is often seen as a panacea to many of the challenges faced by agricultural production in developing countries. Given the large heterogeneity of contract farming arrangements, it is debatable whether all kinds of contract farming arrangements offer benefits to participating smallholders. We apply matching methods to analyze the effects of a public sugarcane outgrower scheme in Ethiopia. Participation in the outgrower scheme significantly reduces the income and asset stocks of outgrowers who contributed irrigated land to the outgrower scheme, while the effect was insignificant for outgrowers who contributed rain-fed land. We provide several explanations and discuss policy implications.

The measurement of urbanization rates and other uses of statistical information, for example the use of historical town growth to measure long-term economic growth, are usually based on an ad hoc population threshold to define and practically classify settlements as towns. The method, however, trades off accuracy and precision for convenience and simplicity. This paper proposes a new threshold that uses the town size distribution together with agricultural data to derive an appropriate cutoff value. The relevance of agricultural income is integrated into the classification scheme through the differential effect of local agricultural endowments on settlement size. The threshold is chosen such that the size of towns above the cutoff is statistically not influenced by local agricultural endowments, while the size of villages, which is below the threshold, is indeed shaped by them. This new approach is practically demonstrated with an application to the urban system of the nineteenth century in the German region of Saxony. This setting is used to investigate the relevance of a different classification for the development of urbanization over time and Gibrat’s law. The results demonstrate that the underlying classification scheme matters strongly for the conclusions drawn from historical urban data. They also indicate that the use of a common population threshold for a comparative analysis or temporal comparisons in a historical context increases the misclassifications of settlements.

This paper identifies several positive synergies between social protection programmes and food security outcomes. One function of social protection is to manage and reduce vulnerability, and several instruments are reviewed – weather-indexed insurance, public works programmes, emergency food aid and buffer stock management – which all contribute to stabilising income and access to food across good and bad years, or between the harvest and the hungry season. Other social protection instruments aim to contribute to raising household income and crop production, for instance agricultural input subsidies or input trade fairs, as well as public works projects that construct or maintain physical infrastructure such as rural feeder roads and irrigation canals. This paper also argues that food security can be strengthened if social justice is introduced to the design and delivery of social protection programmes. Examples reviewed include rights-based approaches such as employment guarantee schemes, community-based targeting and social audits. The paper concludes by arguing for a comprehensive approach to social protection that will achieve sustainable food security, by combining interventions that stabilise income or food production with those that raise income or food production, and are designed and delivered in ways that enhance social justice.

Demand for electricity is derived from the flow of services provided by a household’s durable energy-using appliances. This paper aims to find out the factors which explain the stock of electrical appliances for a household by applying regression analysis. A questionnaire based study for 395 Delhi households was undertaken wherein the sample households were selected on the basis of stratified random sampling technique. To know the lifestyle choices and electricity use habits of the households, socio-demographic variables proved to be very useful. The regression results indicate that the income of the household, family size, house size and the place of the residence explain the variation in the stock of appliance with a household. The education of the head of the household does not influence the stock of electrical appliances with a household.

Whether it is fair to characterize natural resource wealth as a curse is still debated. Most of the evidence derives from cross-country analyses, providing cases both for and against a potential resource curse. Scholars are increasingly turning to within-country evidence to deepen our understanding of the potential drivers, and outcomes, of resource wealth effects. Moving away from cross-country studies offers new perspectives on the resource curse debate and can help overcome concerns regarding endogeneity. Therefore, scholars are leveraging datasets that provide greater disaggregation of economic responses and exogenous identification of impacts. This article surveys the literature on these studies of local and regional effects of natural resource extraction. We discuss data availability and quality, recent advances in methodological tools, and the main findings of several research areas. These areas include the direct impact of natural resource production on local labor markets and welfare, the effects of government spending channels resulting from mining revenue, and regional spillovers. Finally, we take stock of the state of the literature and provide suggestions for future research.

In many developing countries property rights over rural land are maintained through continuous personal use instead of by land titles. We show that removing the link between land use and land rights through the issuance of ownership certificates can result in large-scale adjustments to labor and land allocations. Using the rollout of the Mexican land certification program from 1993 to 2006, we find that households obtaining certificates were subsequently 28 percent more likely to have a migrant member. We also show that even though land certification induced migration, it had little effect on cultivated area due to consolidation of farm units. (JEL O13, O17, P14, Q15, Q18, Q24, Q28)

Under the context of the essential role and growing importance of the rural environment in the development of a country, we focus on evaluating the economic theoretical potential of the rural environment that we consider to have been mismanaged during 1956-2010. For this purpose, in this paper we define, describe and explain the main concepts, as to be able to evaluate the economic potential of the rural development and further contribute to its improvement. The study focuses on the correlations between the population of working age, occupancy, unemployment and the wasted economic potential, putting forward a new concept, statistically valid, demographic named the absolute able overpopulation.

The vast majority of households in low-income countries cook with firewood, which is known to produce various airborne toxins. We examine whether cooking with firewood results in poorer respiratory health by using a unique Indonesian household survey that collected direct measures of lung capacity. We find that individuals living in households that cook with firewood have 11.2 per cent lower lung capacity than those that cook with cleaner fuels. This impact is larger for women and children than for men. The results strongly support the international policy focus on encouraging households to switch to cooking with cleaner fuels.

Energy sectors of most industrialized countries are marked by a long history of state and corporate-owned and highly centralized energy generation (mostly from fossil-based sources) and distribution. Although technological developments and pressures from social/ecological movements resulted in an increased uptake of renewable energy (RE) technologies since the early 1990s, the application of these technologies have since predominantly taken place through largescale projects owned by corporate actors. In response, an increasing number of individuals and community groups have been forming renewable energy cooperatives (RE co-ops) in recent years to provide bottom-up and collective solutions to their local needs and global environmental issues. The goal of this literature review is to summarize the demonstrated impacts of RE co-ops in the economic, social and environmental realms. Thereby, their impact on community development and role in accelerating the transition towards a sustainable energy sector is assessed. Findings of this review show that successful RE co-ops generated positive outcomes for their members and the wider community while accelerating the social and perceptual dimensions of the global energy transition. However, it has also been revealed that RE co-ops’ success in generating positive impacts is often limited by various community-specific factors and by financial and perceptual barriers to their emergence and development.

Local ecosystem services have been significantly affected by land cover changes associated with rapid urbanization in China. Based on the 2000 and 2010 land cover data products with 30-m resolution, we examined the similarities and differences in the impacts of land cover change on ecosystem service values (ESV) at three coastal urban agglomerations in China between 2000 and 2010 (Liaodong Peninsula (LP), Jing-Jin-Ji (JJJ) and Shandong Peninsula (SP)). A rapid evaluation method developed by Xie et al. (2008) was used to derive an ecosystem service value coefficient. The most significant change was an increase in artificial surfaces, due to urban expansion, which mainly occurred on cultivated land. The greatest loss in total ESV (2273 million Chinese Yuan) occurred in SP, due to the large decrease in wetland areas, because this service has the highest estimated coefficient. The second greatest loss in ESV (893 million Yuan) occurred in JJJ, due to the urban expansion of major cities. In contrast, ESV increased (72 million Yuan) in LP. This study demonstrates that urban expansion does not necessarily lead to a net decline in ESV. In conclusion, land use and land cover policymaking should consider the sustainability of ecosystem services in relation to economic growth.

The tree-growing sector is considered to be an important supplier of food and raw material for industry worldwide. Increasingly competitive decisions regarding international investment in orchards depend on business analysis. This study compares three apple orchards situated in Cluj-Napoca, on the Eastern limits of the Transylvanian Plain, Romania. While the climatic and soil conditions are relatively consistent among the three orchards, the technical and economic results (expressed in hectares) vary due to the use of three different technological systems of apple production: extensive, intensive, and super-intensive. The study compares the life cycle, starting with age of fructification, production level (quantity and quality), costs (investment and production costs—divided into material costs, mechanical costs, human costs, and overhead costs), income, profit (including rate of profit), and investment efficiency: Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP). It was observed that the most economically efficient technological system in terms of investments is the super-intensive one, with a higher production level, a higher share of Extra Class apples, and a younger age of initial fructification. However certain inconveniences of this system—such as a more expensive investment, a higher cost of running the business throughout the year, and a reduced life cycle—cannot be ignored.

During the last few years, the issues of energy efficiency and energy saving have dominated the buildings research field. New constructions are based on efficient design and, because of this, the real challenge is to retrofit existing buildings. Italian standards impose thermal transmittance limits for opaque and transparent surfaces, according to the climatic area. In order to understand buildings’ energy behavior, an accurate analysis, carried out by employing advanced calculation codes and instrumental diagnosis—provided by the use of heat flow meter, surface temperature probes and thermal imaging camera—is needed. In this paper, a structure built in the 50 s has been analyzed, by means of a measurement campaign, to investigate the building’s characteristics and its vulnerability. Finally, some retrofit hypotheses have been evaluated by means of a well-known dynamic code. All investments have to be analyzed under a financial point of view, considering materials and installation costs. For this reason, the payback time has been calculated in order to understand how quickly the energy upgrading can be repaid.

With an increased awareness of sustainability issues, natural ventilation has become an elegant method for reducing the costs and environmental effects of the energy that is used to maintain comfortable indoor air quality rather than using mechanical ventilation. The windows in many industrial buildings are continuously open to exhaust pollutants and intake fresh air. Though windows are functional and efficient for natural ventilation, rainwater is able to penetrate through the windows during wind-driven rain. For industries in which the moisture content affects the quality of the product, the intrusion of a large amount of rainwater through windows must be prevented without compromising the effective ventilation. The aim of this research is to determine an innovative design for windows to accomplish the optimum of high ventilation and low rain penetration. For this purpose, windows are variously innovated and tested in full-scale measurements, reduced-scale wind-tunnel measurements and computational fluid dynamics (CFD). An artificial rain and wind velocity to mimic the average of the maximum values in Korea are created. The maximum reduction in rain penetration of over 98% compared to basic 90 degrees open windows is attained with only a 4%-9% decrement of ventilation efficiency in the two recommended designs.

We propose an ethical analysis as a method to reflect on how companies’ decisions promote sustainable development. The method proceeds by first identifying the choice according to financial business interests, and by then scrutinizing this choice according to consequentialist and deontological ethics. The paper applies the method to the choice of an Environmental Impact Assessment (EIA) that a consortium of Brazilian companies (EGASUR) delivered as part of their project proposal for the realization of the Inambari hydropower dam in the Peruvian Amazon. We show that if an EIA is chosen based on the attempt to maximize the financial bottom line, it raises ethical issues both from a consequentialist perspective by involving negative consequences for various stakeholder groups, and from a deontological perspective by not complying with relevant rules, guidelines, and principles. The two ethical perspectives hence reveal where the consortium faces impediments to a genuine commitment to sustainability. Building on stakeholder interviews, observations of the project developments, and the executive summary of the actual EIA, we provide indications that EGASUR has indeed made a choice that resembles a decision based on financial interests.

Even though land reform may be an effective means of reducing poverty, evidence on its causal effects is scant. This paper uses household panel data combined with a quasi- experimental program to assess the impact of a joint Malawi/World Bank land redistribution project on households’ productivity and well-being in southern Malawi. Double difference and matching methods are used to address sources of selection bias in identifying impacts. Results point to average positive effects of the land program on land holdings, agricultural output, income, food security and asset ownership of beneficiary households. Yet, beneficiaries do not see an improvement in access to social services such as schools and health facilities. There is also evidence of heterogeneous effects by gender and inheritance systems. Overall, our findings suggest that there is scope for reducing poverty and inequality in developing countries by implementing a decentralized, community-based, voluntary approach to land reform through the provision of land to land-poor households.

The goal set by the EU of quasi-zero energy buildings is not easy to reach for a country like Italy, as it holds a wide number of UNESCO sites and most of them are entire historical old towns. This paper focuses on the problem of the improvement of energy performance of historical Italian architecture through simple interventions that respect the building without changing its shape and structure. The work starts from an energy analysis of a building located in the historic center of Tivoli, a town close to Rome. The analysis follows the recommendations of the UNI TS 11300-Part1, which indicates how to evaluate the energy consumptions. The calculations were performed only on the building envelope, based on passive solutions and alternatives. Four passive strategies were examined and applied based on the location of the building and the non-alteration of the structure and the landscape. The obtained results impacted positively on the energy performance of the building: the annual energy saving reached a maximum value of 25%. This work shows how it is possible to improve the energy performance of an existing building achieving a significant energy saving with the respect of the building architecture, shape, function and the surrounding landscape.

The classical view of BulgariaÕs failed industrialization prior to the Second World War was established by Alexander Gerschenkron. According to his interpretation, an inherently backward small peasant agriculture and well-organized peasantry not only retarded growth in agriculture but obstructed any possible industrialization strategy. Following Hayami and Ruttan, we utilize the decomposition of farm labor productivity into land productivity, and land-to-man ratio to analyze the sources of growth in BulgariaÕs agriculture 1887-1939. Our results show that BulgariaÕs peasants did cross the threshold to modern growth during the Interwar period. Rich qualitative evidence supports the findings of our quantitative analysis that contrary to GerschenkronÕs view and conventional wisdom, BulgariaÕs peasants substantially contributed to the modernization of BulgariaÕs economy and society. We interpret our results in light of modern development economics, and conclude that agriculture formed no impediment to BulgariaÕs industrialization. The reasons that a Ôlarge industrial spurtÕ did not occur in Bulgaria until 1945 are not to be found in the agricultural sector.

Using a sequential slack-based measure (SSBM) model, this paper analyzes the spatiotemporal disparities of urban land use economic efficiency (ULUEE) under environmental constraints, and its influencing factors in 270 cities across China from 2003–2012. The main results are as follows: (1) The average ULUEE for Chinese cities is only 0.411, and out of the 270 cities, only six cities are always efficient in urban land use in the study period. Most cities have a lot of room to improve the economic output of secondary and tertiary industries, as well as environmental protection work, (2) The eastern region of China enjoys the highest ULUEE, followed by the western and central regions. Super-scale cities show the best performance of all four city scales, followed by large-scale, small-scale and medium-scale cities. Cities with relatively developed economies and less pollutant discharge always have better ULUEE, (3) The results of slack variables analysis show that most cities have problems such as the labor surplus, over-development, excessive pollutant discharge, economic output shortage, and unreasonable use of funds is the most serious one, (4) The regression results of the influencing factors show that improvements of the per capita GDP and land use intensity are helpful to raise ULUEE. The urbanization rate and the proportion of foreign enterprises’ output account for the total output in the secondary and tertiary industries only have the same effect in some regions and city scales. The land management policy and land leasing policy have negative impact on the ULUEE in all the three regions and four city scales, (5) Some targeted policy goals are proposed, including the reduction of surplus labor, and pay more attention to environmental protection. Most importantly, effective implementation of land management policies from the central government, and stopping blind leasing of land to make up the local government’s financial deficit would be very helpful to improve the ULUEE of Chinese cities.

Urban development in China has attracted considerable scholarly attention. However, more work is still needed to examine and understand the mechanisms of urban land expansion, especially within the context of globalization/marketization, decentralization and urbanization. This paper analyzes urban land expansion and structural changes in the Yangtze River Delta (YRD). We find that cities in the YRD are experiencing urban land expansion mainly characterized by the growth of residential and industrial land. The dominant characteristics of urban land expansion in cities have also varied within different development and administrative levels. Based on our conceptual framework, we have used multi-models to investigate the driving forces of urban land expansion and structural changes in the YRD. The results reveal that six influencing factors—foreign direct investment (FDI), labor, government competition, institution, population, and job-housing relations—facilitate land use change in the economic transition process. However, their impacts differ in cities in different geographical locations, as well as with different administrative levels. Finally, this paper discusses policies to promote sustainable urban land use in the YRD.

As global green trends became more prevalent, green marketing also developed into an important issue. Although prior literature explored the main factors affecting green trust, it was inconclusive as to how environmental friendliness could affect the green trust in green marketing. This study aims to focus on the positive influence of environmental friendliness on green trust, and explore the mediation effects of green satisfaction and green perceived quality. This study undertakes an empirical study by means of questionnaire survey. The respondents are consumers who have experience purchasing green products. This study applies structural equation modeling (SEM) to test the hypotheses. The findings of this study indicate that (1) environmental friendliness has a significant positive impact on green satisfaction, green perceived quality, and green trust, (2) both green satisfaction and green perceived quality positively affect green trust, and (3) green satisfaction and green perceived quality partially mediate the positive relationship between environmental friendliness and green trust.

Carbon footprints have been widely employed as an indicator for total carbon dioxide released by human activities. In this paper, we implemented a multi-regional input-output framework to evaluate the carbon footprints and embodied carbon flows for the eight regions of China from consumption-based perspective. It is found that the construction, electricity/stream supply, and machine manufacturing rank as the top sectors with the largest total carbon emissions. The construction sector alone accounts for 20%–50% of the national emissions. Besides the sectoral carbon footprints, regional footprints and their differences in carbon emissions were also observed. The middle region had the largest total carbon footprints, 1188 million ton, while the capital region ranked the first for its per capita carbon footprint, 7.77 ton/person. In regard to the embodied carbon flows within China, the study detected that the embodied carbon flows take up about 41% of the total carbon footprints of the nation. The northwest region and the eastern coast region are found to be the largest net embodied carbon exporter and importer, respectively. Further investigation revealed significant differences between production-based and consumption-based carbon emissions, both at sectoral and total amounts. Results of this paper can provide specific information to policies on sectoral and regional carbon emission reduction.

Landsat images from 1979, 1988, 1999, 2008, and 2013 were used to analyze the landscape area change of salt pans lying on the coast of Tianjin. While initially (1979–1988), the area of Tianjin’s salt pan increased, later (1988–2013) it declined dramatically. In the first phase (1979–1988) of the studied period the primary roll-in landscape of the salt pan wasbarren land with an area of 60.0 km 2 . By 1988, the area of Tianjin’s salt pan rose to 457.8 km 2 . The main roll-out landscape of the salt pan during 1988–2013 was urban, barren land, village/town, harbor, and road whose area amounted to 69.8, 35.9, 27.3, 25.5 and 18.4 km 2 respectively. The roll-out barren land will be transformed to construction land ultimately. By 2013, the total loss reached 167.3 km 2 , which was 36.5% of the salt pan area of Tianjin in 1988. With the development of coastal economy, the salterns with a lower economic value were transformed to and replaced by land use types with a higher economic value. This trend would influence the production of sea salt and the development of sodium hydroxide and sodium carbonate industries. Seawater desalination provides an opportunity for the restoration and compensation of salt production capacity. Based on the theory of circular economy and industrial symbiosis, in this article an industrial symbiosis model for sea salt production and sea water desalination is explored: “mariculture–power plant cooling–seawater desalination–Artemia culture–bromide extraction–sea salt production–salt chemical industry”. Through the application of this process sustainable development of the sea salt production in Tianjin could be achieved.

Urban ecological vulnerability is measured on the basis of ecological sensitivity and resilience based on the concept analysis of vulnerability. GIS-based multicriteria decision analysis (GIS-MCDA) methods are used, supported by the spatial analysis tools of GIS, to define different levels of vulnerability for areas of the urban ecology. These areas are further classified into different types of regulatory zones. Taking the city of Hefei in China as the empirical research site, this study uses GIS-MCDA, including the index system, index weights and overlay rules, to measure the degree of its ecological vulnerability on the GIS platform. There are eight indices in the system. Raking and analytical hierarchy process (AHP) methods are used to calculate index weights according to the characteristics of the index system. The integrated overlay rule, including selection of the maximum value, and weighted linear combination (WLC) are applied as the overlay rules. In this way, five types of vulnerability areas have been classified as follows: very low vulnerability, low vulnerability, medium vulnerability, high vulnerability and very high vulnerability. They can be further grouped into three types of regulatory zone of ecological green line, ecological grey line and ecological red line. The study demonstrates that ecological green line areas are the largest (53.61% of the total study area) and can be intensively developed, ecological grey line areas (19.59% of the total area) can serve as the ecological buffer zone, and ecological red line areas (26.80%) cannot be developed and must be protected. The results indicate that ecological green line areas may provide sufficient room for future urban development in Hefei city. Finally, the respective regulatory countermeasures are put forward. This research provides a scientific basis for decision-making around urban ecological protection, construction and sustainable development. It also provides theoretical method references for future research into urban ecological vulnerability, including the introduction of GIS-MCDA methods into the field of urban ecological vulnerability, which expands the application for these techniques.

The evolution of Eco Industrial Parks (EIPs) in Italy is a development opportunity for many territories and companies. Starting from the initial experiences in the 1980s, the Eco Industrial Parks model has spread throughout many of the central and northern regions of the country. The key element of Italian Eco Industrial Parks is the management body, an entity provided by national legislation to manage and coordinate companies and to develop more environmentally sustainable production practices. The survey results describe the role and activities of the management bodies concerning the actions implemented, the interaction with the main stakeholders and the resources and investments. The following research introduces an important environmental management experience implemented in Italy.

A question fundamental to sustainable economic growth is whether a poor region tends to grow faster than a rich one, such that the poor region catches up with the rich region in terms of the level of per capita income. In this article, we apply the spatial panel data approach to the analysis of regional income convergence across 177 economic areas in the contiguous US states over the period from 1969 to 2009. Using data on per capita incomes in the functionally defined economic areas, we find that the absolute value of the estimated coefficient of the initial per capita income decreases in the spatial and time-period fixed effects spatial lag model and increases in the spatial and time-period fixed effects spatial error model. This result implies that the growth rate in a specific economic area will be not only directly affected by an exogenous shock introduced into that economic area but also be impacted more by both the indirect effects of the first-order neighboring economic areas and the induced effects of the higher-order neighboring economic areas. This gives helpful hints on the issue of spatial interaction and regional policy coordination to start a virtuous circle of sustainable economic growth.

Sustainability of nonprofit organizations is a key concern for today’s nonprofit scholars and practitioners. Building upon the nonprofit economics literature, the present paper introduces the distinction between the demand-side and supply-side determinants of nonprofit sustainability and makes the case for the discrepancy between them. This discrepancy presents not only a generic conceptual explanation of the nonprofit sustainability problems but is also applicable to the context of the European rural nonprofit sector. Three arguments are advanced. First, the notorious implementation problems of LEADER partnerships can be explained as a manifestation of the above discrepancy. Second, and related, the rural context implies the tendency of the supply-side determinants of nonprofit sustainability to undermine the demand-side ones. Third, recent empirical findings from the Czech Republic show that this tendency does not necessarily imply the possibility of a clear classification of the demand-side and supply-side sustainability determinants. Rather, those features of rural areas and communities that significantly affect the size of the local nonprofit sector exhibit a controversial entanglement of demand-side and supply-side identities.

Frequent fire accidents pose a serious threat to human life and property. The spatio-temporal features of China’s urban fires, and their drivers should be investigated. Based on the Spatio-temporal Dynamic panel data Model (SDM), and using fire data gathered from 337 Chinese cities in 2000 to 2009, the influence of spatio-temporal factors on the frequency of urban fires was analyzed. The results show that (1) the overall fire incidence of China increased annually before 2002 and reduced significantly after 2003, and then high fire incidence increased in western China, (2) Spatio-temporal factors play a significant role in the frequency of Chinese urban fires, specifically, the fire assimilation effect, fire inertia effect and fire caution effect. The ratio of fire incidence of China has reduced significantly, and the focus of fire incidence moved towards the western region of China. GDP and humidity have a significant effect on urban fire situation change in China, and these effects may be referred to as “fire assimilation effects”, “fire inertia effects” and “fire caution effects”.

The global decline in estuarine and coastal ecosystems is affecting critical ecosystem services. The spatial agglomeration of population, industries and resources has led to the emergence of regionally-specific ecological problems. Therefore, identifying “ecological red lines”, based on specific natural and environmental features, could help to differentiate the economic development and ecological protection directions or potentials of different regions in future. The aim of this case study is to define the ecological red line in the coastal zone of Liaoning Province, China, by evaluating the ecological importance and environmental stress in its marine and terrestrial ecosystems. For this purpose, the ecological importance of this area was first classified into four conservation indices (species, wetland, water and coast and islands) and assigned values of 5, 3 and 1 for indications of high, moderate and minor importance. In the meantime, environmental stress was also classified into four indices (water environment, salinization, soil erosion and erosion of coasts and islands) and assigned values of 5, 3 and 1 for indications of high, moderate and low stress, respectively. Then, based on an overlay analysis and evaluation of the above results, we defined two grades of ecological red line zones. Grade I ecological red line zones contain the areas with critical and diverse ecosystem services, areas of high importance for species conservation and nature reserves, as well as ecologically-vulnerable and sensitive areas. It is important in these areas to maintain the biological diversity and to improve the quality of the ecological environment, which should be strictly protected and explicitly controlled. Grade II ecological red line zones display areas with minimum requirements for maintaining the basic needs of a livable environment and human health, moderate to minor levels of ecological importance and high to moderate levels of environmental stress. To better control and protect such ecological red lines, setting up an ecological inventory through remote sensing satellites and ground-level monitoring and appraising the effectiveness of dynamical protection are highly recommended.

This study examined two-level (road environments and census tracts) built environments related to the probability of severe injury for pedestrians. In total, 1407 pedestrian–vehicle crashes (years 2008–2012) were identified from 140 census tracts in the city of Austin. Two multilevel models were applied to examine pedestrian injury severity by using level-1 factors (individual characteristics, road environments, and area characteristics around the crash location) and level-2 factors (characteristics of census tracts). The results demonstrated the importance of using the multi-level model to avoid the biased results from employing the single-level model. This study showed that the likelihood of being severely injured or killed decreased when vehicles turned left, when crashes occurred at intersections, when there were traffic control devices at the crash location, and when crashes occurred during inclement weather conditions. Areas with higher sidewalk densities and higher percentage of commercial uses were negative correlates, while population density was a positive predictor. Pedestrian injury severity has been and will continue to be an important topic for the fields of public health. Future safety programs should focus on providing connected sidewalks and on populated areas.

Water availability has become a problem in many countries of the world. Water scarcity can be economic or physical. Agricultural water use accounts for about three quarters of total global consumption, in many developing countries, irrigation represents over 90% of the water used. The purpose of this paper is to explore the willingness to pay for irrigation water among the farmers from the boundaries governed by the Kurdistan Regional Government (KRG). During the field study, 236 farmers from KRG were interviewed. The collected data were analyzed for each of the precipitation zones of the area (secured (A) and non-secured rainfed (B)). The contingent valuation method was used to determine the willingness to pay for irrigation water. The following possible independent variables influencing farmers’ decisions were considered: the bid amounts, evaluation scale of the water deficit, source of water for irrigation, cultivated area, education and age of respondents, main agricultural activity. In Zone A, the median willingness to pay of the farmers that used ground water for irrigation is 20.28 USD/10 m3, and for the farmers that use other sources of water, the willingness to pay is 11.49 USD/10 m3. The median willingness to pay in Zone B is 18.56/10 m3.

A key strategy of sustainable transportation, parking pricing can directly contribute to decreased greenhouse gas emissions and air pollution. This paper describes an optimal structure of parking rates in terms of parking locations and time of day. A two-level parking model based on game theory is established using parking survey data collected in Beijing in 2014. The model was estimated based on Stackelberg game and the Nash equilibrium. Using the two-level parking model, the optimal structure of parking rates for inside/outside business zones and during peak/off-peak hours was calculated. In addition, the relationship between the government (which represents the public benefit) and car users, as well as the relationships among car users in the parking system were investigated. The results indicate that equilibrium among all of the agents in the parking system can be obtained using the proposed parking rate structure. The findings provide a better understanding of parking behavior, and the two-level parking model presented in the paper can be used to determine the optimal parking rate to balance the temporal and spatial distribution of parking demand in urban areas. This research helps reduce car use and the parking-related cruising time and thus contributes to the reduction of carbon emissions and air pollution.
