The aim of this policy paper is to characterize the current situation of Tunisian municipalities in matters of climate change policies and actions and to understand the barriers and best practices. By surveying municipalities in Tunisia, we were able to provide an overview of the Tunisian municipalities in matters of climate change actions and strategies, as well as finding the main barriers and best practices. First, we found that most Tunisian municipalities are facing different effects of climate change. Second, the majority of municipalities do not have a strategy for mitigation and adaptation of climate change at the local level. Third, the main barrier that municipalities face in investing in climate change actions is the lack of financial resources and funding. Four, we have identified some of the best climate change mitigation and adaptation practices of surveyed cities, which should be taken into consideration and implemented also by the other cities.

Currently, we find ourselves in a paradigm in which we believe that accepting climate change data will lead to a kind of automatic action toward the preservation of our environment. I have argued elsewhere (Fried 2020) that this lack of civic action on climate data is significant when placed in the historical, military context of the technologies that collect this data––Earth remote sensing technologies. However, I have not yet discussed the phenomenological or moral implications of this context, which are deeply interconnected. In this paper, I assert that Earth remote sensing technologies can, if we are not careful, lead us to a kind of environmental deskilling. This assertion comes in four parts. First, the military context of Earth remote sensing technologies––which collect important data on climate change––acts as a kind of stability, as defined by Don Ihde and others. Second, I invoke Sir Patrick Heelan to argue that the theoretical underpinnings of Earth systems science do not translate from military to environmental praxes as we imagine they do. Third, Hannah Arendt makes the case that a state's trust in simplifying narratives like that of climate data, meant to create "islands" of certainty in an uncertain world, can be self-defeating. That is to say, they can silence public action. I extend these arguments through Vallor's analysis of moral deskilling, in which she points out that an overemphasis on autonomous data collection––and trust in a kind of automated decision-making on that data––can deskill us from important questions relevant to our collective flourishing. In all of these examples, the lines between environmental and military research are blurry. [ABSTRACT FROM AUTHOR]

The major cause of soil degradation (contamination, erosion, compaction) is closely linked to agriculture, i.e., unsustainable agriculture practices, which are reflected in the depletion of the soil organic carbon pool, loss in soil biodiversity, and reduction of C sink capacity in soils. Therefore, the agricultural practice of applying carbon-rich materials into the soil is an attractive solution for climate change mitigation and soil ecosystem sustainability. The paper aimed to evaluate the effectiveness of the addition of organic-mineral mixtures to the mineral salts (NPK), including the exogenous organic matter (lignite) mixed with zeolite-carbon (NaX-C) or zeolite-vermiculite (NaX-Ver) composites in the restoration of soils contaminated with PAHs. The addition of zeolite composites to fertilizer resulted in a significant reduction in soil PAH levels and a corresponding reduction in plant tissue content, without compromising yields, compared to the control and separate application of NPK. A Significant correlation between PAHs and pHH2O, pHKCl, EC and dehydrogenase activity (DhA) was found in soils. The addition of zeolite composites with lignite significantly reduced the content of PAHs in straws, especially following the application of NaX-C. However, in the case of grains, the highest percentage reduction in comparison to NPK was observed for the highest dose of NaX-Ver. [ABSTRACT FROM AUTHOR]

The influences of human activity on regional climate over China have been widely reported and drawn great attention from both the scientific community and governments. This paper reviews the evidence of the anthropogenic influence on regional climate over China from the perspectives of surface air temperature (SAT), precipitation, droughts, and surface wind speed, based on studies published since 2018. The reviewed evidence indicates that human activities, including greenhouse gas and anthropogenic aerosol emissions, land use and cover change, urbanization, and anthropogenic heat release, have contributed to changes in the SAT trend and the likelihood of regional record-breaking extreme high/low temperature events over China. The anthropogenically forced SAT signal can be detected back to the 1870s in the southeastern Tibetan Plateau region. Although the anthropogenic signal of summer precipitation over China is detectable and anthropogenic forcing has contributed to an increased likelihood of regional record-breaking heavy/low precipitation events, the anthropogenic precipitation signal over China is relatively obscure. Moreover, human activities have also contributed to a decline in surface wind speed, weakening of monsoon precipitation, and an increase in the frequency of droughts and compound extreme climate/weather events over China in recent decades. This review can serve as a reference both for further understanding the causes of regional climate changes over China and for sound decision-making on regional climate mitigation and adaptation. Additionally, a few key or challenging scientific issues associated with the human influence on regional climate changes are discussed in the context of future research. [ABSTRACT FROM AUTHOR]

Due to the severe effects of climate change on the agricultural sector, urgent action is required on the part of farmers and is, indeed, critical to reducing climate change impacts. However, reports globally revealed farmers' engagement in climate change adaptation is still insufficient, ambivalent, and inconsistent and farmers do not consider adaptation to be urgent. Researchers have argued that this issue is rooted in psychological biases beside other factors. Therefore, the aim of this study is to evaluate how psychological distance determines climate change beliefs, risk perception and adaptation strategies among Iranian farmers. A cross-sectional paper-based survey was conducted in the Dasht-e Azadegan county of Khuzestan province in southwest Iran. The study sample consisted of 250 farmers selected through a multi-stage random sampling process. An expert panel review and a pilot study were conducted to confirm convergent validity and reliability of the scales. The results confirm that all four dimensions of psychological distance influence water management adaptation strategies and non-farm activities. Moreover, all psychological dimensions, except the temporal dimension, affect adaptation in farming management. Thus, making climate change more proximal to decision makers could be a strategic way of encouraging individuals to take adaptive actions. This study emphasizes that concepts of psychological distance can be applied to help organizations (e.g., agriculture extension services) to understand farmers' risk perceptions and responses to climate change impacts and improve risk communication to better engage farmers in climate action.

Uncertainty sources in climate change impact studies can be addressed in two distinct phases, climate modelling and impact assessment. Generally, uncertainty from the climate modelling phase is the larger contributor and the impact phase uncertainty is sometimes marginalized. This paper aims to develop integrated uncertainty analysis approaches that deal with uncertainties at the impact level with all sources included. The existing uncertainty analysis method of Reliability Ensemble Averaging (REA) is modified for impact studies by bracketing the hydrological model parameter uncertainty. A novel probabilistic approach referred to as Bootstrapped Ensemble Uncertainty Modelling (BEUM) is also proposed for uncertainty analysis at the impact phase. Modified REA and BEUM are applied to streamflow projections of the Hulu Langat basin with uncertainties stemming from emission scenarios, general circulation models (GCM), downscaling method, and a hydrological model parametrization for a comprehensive integrated uncertainty assessment. The modified REA increased the reliability measure of each streamflow scenario and improved the uncertainty coverage percentage when compared with the original REA. The REA eliminated the projections of the less reliable GCMs, and therefore reduced uncertainty bands compared to the BEUM. The BEUM can create a large ensemble of streamflow projections through nonparametric bootstrapping of the limited impact scenarios and define the streamflow distribution for every quantile. Therefore, BEUM is able to encompass larger uncertainty intervals and explain the behavior of ensemble members through probabilistic distributions that can assist in decision making for climate change mitigation and adaptation planning.

Africa is particularly vulnerable to climate change impacts, which threatens food security, ecosystem protection and restoration initiatives, and fresh water resources availability and quality. Groundwater largely contributes to the mitigation of climate change effects by offering short- to long-term transient water storage. However, groundwater storage remains extremely difficult to monitor. In this paper, we review the strengths and weaknesses of satellite remote sensing techniques for addressing groundwater quantity issues with a focus on GRACE space gravimetry, as well as concepts to combine satellite observations with numerical models and ground observations. One particular focus is the quantification of changes in groundwater resources in the different climatic regions of Africa and the discussion of possible climatic and anthropogenic drivers. We include a thorough literature review on studies that use satellite observations for groundwater research in Africa. Finally, we identify gaps in research and possible future directions for employing satellite remote sensing to groundwater monitoring and management on the African continent. Article Highlights: Overview on the distribution and characteristics of African groundwater resources including future projections Combination of satellite and in situ observations with numerical models allows us to obtain a synoptic view of groundwater-related processes Summary of current concepts and achievements of satellite remote sensing-based groundwater monitoring and decision making over Africa [ABSTRACT FROM AUTHOR]

Tropical inland capture fisheries are susceptible to a series of vulnerabilities such as habitat destruction, biodiversity loss, pollution, overfishing, invasive species and anthropogenic climate change. A comprehensive review of the impact of climatic uncertainties on Indian inland fisheries has not been adequately attempted yet. Recent approaches emphasizing ecosystem-based management in a regional context, specific to inland fisheries for combating climatic changes, have not been reported to date. The paper presents a critical bibliometric review of the climatic vulnerabilities faced by Indian inland fishery resources and various adaptive and mitigation strategies put forward by the country for the sustainability of the resources. In this communication, a systematic review of the impact of climate change and other stressors on various inland ecosystems of the subcontinent and the ecosystem-based management strategies adopted in India is presented and discussed.

Introduction: Climate change is among the most renowned concerns of the current century, endangering the lives of millions of people worldwide. To comply with the United Nations Climate Change Conference (COP21), hospitals should be on track to reduce greenhouse gas emissions. Although hospitals contribute to climate change by emitting greenhouse gases, they are also affected by the health consequences of climate change. Despite all the guidance provided, hospitals need more radical measures to confront climate change. The current study was carried out to examine the components of hospitals' adaptation to climate change and to review measures to confront climate change in hospitals. Method: This systematic review was designed and carried out in 2020. The required information was collected from international electronic databases including Scopus, PubMed, Web of Science, EMBASE, and Google Scholar. Moreover, Iranian datasets such as Scientific Database (SID), Irandoc, Magiran, and IranMedex were reviewed. No restriction was considered in the methodology of the study. For the relevant thesis, the ProQuest database was also explored. The related sources were examined and the Snowball method was applied to find additional related studies. The research team also reviewed other accessible electronic resources, such as international guidelines and academic websites. The checklist of the Joanna Briggs Institute (JBI, 2017) was employed in order to evaluate the quality of the included papers. The studies published until June1, 2020, were included in the study. Results: Of 11,680 published documents in the initial search, the full-texts of 140 were read after evaluating the titles and abstracts, of which 114 were excluded due to lack of sufficient information related to countermeasures in hospitals. Finally, the full-texts of 26 studies were reviewed to extract the required components. Two strategies were found, including climate change mitigation and climate change adaptation, with 13 components including water, wastewater, energy, waste, green buildings, food, transportation, green purchasing policy, medicines, chemicals and toxins, technology, sustainable care models, and leadership in hospitals were identified as affecting these measures and strategies. Conclusion: Considering the significance of climate change and strategies to confront it as one of the current challenges and priorities in the world, it is necessary to develop a framework and model to reduce the effects of climate change and adapt to climate changes in hospitals and other health centers. The identification and classification of the measures and components, influencing hospital adaptability and solutions for reducing the climate change impacts could be the first stage in developing this strategy. This is because it is impossible to create this framework without identifying these factors and their mutual impacts at the first. In the present study, through a systematic review using a comprehensive approach, the related components were explored and divided into two categories, including measures to reduce the effects and measures to adapt to climate change. The results of this study can be useful in developing a comprehensive action model to reduce greenhouse gas emissions and adapt hospitals to climate change. [ABSTRACT FROM AUTHOR]

An increase in energy demand and consumption is one of the significant challenges of the world community. Global climate change and temperature rise can significantly affect energy demand, especially in the building sector. Green passive design strategies (GPDS) such as green roof and green wall are considered a passive energy-saving technology which can deal with further climate change in near future. This paper compares the energy demand and CO2 emissions of a building with different structural scenarios during the current (2000–2019) and future climatic conditions (the 2050s) in two hot-dry (Kerman) and hot-humid (BandarAbbas) climate samples in Iran. The base case, green roof, and green wall modeling of the selected building have been developed by DesignBuilder software. Results revealed that 61% of the annual energy consumption of Kerman is related to the heating sector, while it will be changed to 47% under the effect of climate change and based on RCP2.6. However, 99% of the annual energy consumption of BandarAbbas belongs to cooling demand and it will not change by 2050s. Also, the maximum heating and cooling energy demand were calculated for the base building. Based on the results, green wall has more efficiency in optimizing total energy consumption compared to green roof in both climate types. On the other hand, GPDS are more efficient to optimize heating energy demand in comparison with cooling energy demand. Furthermore, the green wall strategy has better performance in reducing CO2 emissions as well. Accordingly, CO2 emissions reduce in Kerman by 2.73% and 2.93% by the implementation of the green wall during the observation period and 2050s, respectively. Meanwhile, this strategy can reduce CO2 emissions by only 1% per year in BandarAbbas during all studied periods. [ABSTRACT FROM AUTHOR]

Soil and other Earth scientists who conduct research on C management found themselves, in the past decade within a swirl of efforts concerning climate mitigation, economic and business investments in carbon markets, and political aspirations. All these external pressures are issues with which soil science is largely unfamiliar. As a result, science has responded without deeply considering the landscape in which it finds itself, and some of the unanticipated challenges these issues present. Here, we suggest soil C scientists now consider and respond to these issues. The first order challenge is to transition from the concept of technical carbon sequestration potentials, made in the absence of social and policy contexts, to societally achievable sequestration estimates based on highly transdisciplinary teams of natural and social sciences and scientists. To achieve this will requires re-thinking national science funding programs, in which climate-relevant social science is under-funded. In addition, the science of soil C itself is in need of a priority shift. Presently, publications in soil C sequestration out-strip papers on soil feedbacks to climate change, and on how to adapt soil to climate change: two areas of research which may well be more societal important in the next few decades than sequestering C. Most seriously, given the urgent nature of our collective societal climate problem, our profession must not find itself a decade from now continuing the now 20-year-old narrative that soil C can potentially mitigate climate change and compensate for greenhouse gas emissions. We must consider the possibility that other options and expenditures of resources are more viable, and we must reframe our science's objectives to expand into the many other urgent needs that confront humanity.

The 26th Conference of the Parties (COP26) to the United Nations Framework Convention on Climate Change (UNFCCC) was held in Glasgow a year later than scheduled, with expected outcomes achieved under a post-pandemic background. Based on the Issue-Actor-Mechanism Framework, this paper systematically evaluates the outcomes achieved at COP26 and analyzes the tendency of post-COP26 climate negotiations. Overall, with the concerted efforts of all parties, COP26 has achieved a balanced and inclusive package of outcomes and concluded six years of negotiations on the Paris Rulebook. It is fair to say that COP26 is another milestone in climate governance following the implementation of the Paris Agreement. Meanwhile, the Glasgow Climate Pact has cemented the consensus on a global commitment to accelerating climate action over the next decade and reached a breakthrough consensus on reducing coal, controlling methane, and halting deforestation. In the post-COP26 era, we still need to take concrete actions to implement the outcomes of the Paris Agreement and the Glasgow Climate Pact, innovate ways to speed up CO2 emissions reduction, and continue to strive for breakthroughs in important issues such as finance, technology, adaptation, and collaboration. In addition to avoiding the escalation of international conflicts, we need to collectively and properly handle the relationship between energy security, carbon reduction, and development and facilitate the efforts of countries to achieve their Sustainable Development Goals (SDGs), including climate-related goals. China will continue to maintain the existing multilateral mechanisms and processes for climate governance, unremittingly take concrete actions to address climate change, promote a domestic comprehensive green transition and global cooperation on carbon neutrality, and contribute constructively to global climate governance.

Research on climate change mitigation and adaptation is pressing in order to understand its implications and risks in different urban areas. It is especially critical for those who face high degrees of urban inequality in the context of an uneven state presence. This paper is an explorative and investigative study which uses Cairo as a case. The focus of the study is on mapping state and private sector efforts in mitigating climate change issues, specifically for vulnerable groups who have limited access to public services. The study adopted an investigative approach where a literature search and bibliometric mapping were used to identify the gap in knowledge in the field of architecture and urban climate change mitigation and adaptation, followed by a field survey which included conducting interviews and questionnaires with different stakeholders from the public and private sector to investigate the link between the efforts for climate change mitigation. The explorative part of the study concluded that there is a huge knowledge gap in the Middle East and in Egypt when it comes to research efforts related to climate change with a focus on the built environment. The results of the investigative part of this study revealed that—apart from already limited efforts on ground—there is no synchronization in efforts between the public and private sector. Climate change issues are still not a priority when poverty, economy, and health are still a prime concern and take precedence over climate change. There is uneven presence of public efforts for climate change adaptation and mitigation. The efforts that do exist in the public sphere are self-help unorganized work (efforts) conducted by the civil society. [ABSTRACT FROM AUTHOR]

Uncertain future payoffs and irreversible costs characterize investment in climate change adaptation and mitigation. Under these conditions, it is relevant to analyze investment decisions in a real options framework, as this approach takes into account the economic value associated with investment time flexibility. In this paper, we provide an overview of the literature adopting a real option approach to analyze investment in climate change adaptation and mitigation, and examine how the uncertain impacts of climate change on the condition of the human environment, risk preferences, and strategic interactions among decisions-makers have been modeled. We found that the complex nature of uncertainties associated with climate change is typically only partially taken into account and that the analysis is usually limited to decisions taken by individual risk neutral profit maximizers. Our findings call for further research to fill the identified gaps. [ABSTRACT FROM AUTHOR]

According to some scholars, while sets of greenhouse gases emissions generate harms deriving from climate change, which can be mitigated through collective actions, individual emissions and mitigation activities seem to be causally insufficient to cause harms. If so, single individuals are neither responsible for climate harms, nor they have mitigation duties. If this view were true, there would be collective responsibility for climate harms without individual responsibility and collective mitigation duties without individual duties: this is puzzling. This paper explores a way to solve this puzzle. First, it will be argued that individual emissions, though not proper and full-fledged causes, causally contribute to raise the probability of climate harms. As a consequence, individuals are in fact responsible for their expected contributions to climate harms - this is contributive responsibility for likely outcomes. Second, it will be argued that people have responsibility also for the possible impacts of their individual emissions on climate harms. People can plausibly be regarded as individually responsible for the possible outcomes of their actions in close possible alternative worlds - this is robust responsibility. Non-causal individual responsibility for climate harms is plausible, and the puzzle may be solved. [ABSTRACT FROM AUTHOR]

Although in recent years great emphasis has been placed on global agreements and national commitments on climate change, ultimately action on mitigation and adaptation must take place at the local level. Many local authorities have to face questions of whether they should develop policies on climate change, and if so, on what evidence should policies be designed and delivered. This paper describes how academic research on the economics of low carbon cities (the 'mini-Stern review') helped create such an evidence base for the Leeds City Region and its constituent local authorities. We describe how the response to the evidence and the pathways to impact were different in the individual local authorities and what this means for our understanding of evidence in local policy making. In terms of Weiss' (Social sciences and modern states: national experiences and theoretical crossroads. Advances in political science, Cambridge University Press, Cambridge, ) classification, the study was mainly useful as an argument and idea rather than being used instrumentally. We find that the policy and political context in each authority determines to a large extent whether such an academic study is useable as evidence. The contents and timing of the study need to align with existing policy and/or political agendas: is climate change on the agenda at all, with what priority and how is it framed. We find confirmation of a relationship between the policy problem type and the role of evidence as argument, idea or data. The mini-Stern study itself was just one contribution to wide-ranging processes of informing, convincing, pressurising, etc., not just within the different councils but also within the wider communities. Other contextual factors include composition, agenda and activities of local civil society and the local business community. Finally, it depends on the expertise of policy officers in the councils what use is made of evidence. Making policy takes (much) time, translation and negotiation across levels and sectors. Policy work describes how policy officers bring their diverse forms of knowledge to bear on policy questions; how this work is done is something that is learned from practice rather than from the study.

The North Pacific Oscillation (NPO) recently (re-)emerged in the literature as a key atmospheric mode in Northern Hemisphere climate variability, especially in the Pacific sector. Defined as a dipole of sea level pressure (SLP) between, roughly, Alaska and Hawaii, the NPO is connected with downstream weather conditions over North America, serves as the atmospheric forcing pattern of the North Pacific Gyre Oscillation (NPGO), and is a potential mechanism linking extratropical atmospheric variability to El Niño events in the tropical Pacific. This paper explores further the forcing dynamics of the NPO and, in particular, that of its individual poles. Using observational data and experiments with a simple atmospheric general circulation model (AGCM), we illustrate that the southern pole of the NPO (i.e., the one near Hawaii) contains significant power at low frequencies (7-10 years), while the northern pole (i.e., the one near Alaska) has no dominant frequencies. When examining the low-frequency content of the NPO and its poles separately, we discover that low-frequency variations (periods >7 years) of the NPO (particularly its subtropical node) are intimately tied to variability in central equatorial Pacific sea surface temperatures (SSTs) associated with the El Niño-Modoki/Central Pacific Warming (CPW) phenomenon. This result suggests that fluctuations in subtropical North Pacific SLP are important to monitor for Pacific low-frequency climate change. Using the simple AGCM, we also illustrate that variability in central tropical Pacific SSTs drives a significant fraction of variability of the southern node of the NPO. Taken together, the results highlight important links between secondary modes (i.e., CPW-NPO-NPGO) in Pacific decadal variability, akin to already established relationships between the primary modes of Pacific climate variability (i.e., canonical El Niño, the Aleutian Low, and the Pacific Decadal Oscillation).

Using wood as a building material affects the carbon balance through several mechanisms. This paper describes a modelling approach that integrates a wood product substitution model, a global partial equilibrium model, a regional forest model and a stand-level model. Three different scenarios were compared with a business-as-usual scenario over a 23-year period (2008-2030). Two scenarios assumed an additional one million apartment flats per year will be built of wood instead of non-wood materials by 2030. These scenarios had little effect on markets and forest management and reduced annual carbon emissions by 0.2-0.5% of the total 1990 European GHG emissions. However, the scenarios are associated with high specific CO emission reductions per unit of wood used. The third scenario, an extreme assumption that all European countries will consume 1-m sawn wood per capita by 2030, had large effects on carbon emission, volumes and trade flows. The price changes of this scenario, however, also affected forest management in ways that greatly deviated from the partial equilibrium model projections. Our results suggest that increased wood construction will have a minor impact on forest management and forest carbon stocks. To analyse larger perturbations on the demand side, a market equilibrium model seems crucial. However, for that analytical system to work properly, the market and forest regional models must be better synchronized than here, in particular regarding assumptions on timber supply behaviour. Also, bioenergy as a commodity in market and forest models needs to be considered to study new market developments; those modules are currently missing. [ABSTRACT FROM AUTHOR]

Issues of social responsibility, ethics and interdependence, as well as the pragmatic imperative to better understand complexity, require that diverse viewpoints be invited and given credence by policy makers seeking imaginative 'solutions' to climate change. This paper explores the statutory introduction of biofuels into New Zealand by way of the discourses that preceded this decision. This inquiry used Critically Systemic Thinking and 'Mode 2' Soft Systems Methodology (SSM) to engage with multiple stakeholders to the Biofuels policy to discover how the discourse was conducted. It concludes that the process of policymaking was framed in technical rationalist terms thereby favouring certain 'worldviews' over others. Accordingly, a model of 'ideal' discourse and decision making for governing the conduct of future public discourse is presented. This inquiry assists in re-establishing SSM as a rigorous and reflexive approach to analysing a complex issue and for enhancing collective learning into its content and process.

Background: Although there is broad agreement that negative carbon emissions may be required in order to meet the global climate change targets specified in the Paris Agreement and that carbon sequestration in the terrestrial biosphere can be an important contributor, there are important accounting issues that often discourage forest carbon sequestration projects. The legislation establishing the California forest offset program, for example, requires that offsets be "real, additional, quantifiable, permanent, verifiable, and enforceable". While these are all clearly desirable attributes, their implementation has been a great challenge in balancing complexity, expense, and risk. Most forest offset protocols carry similar accounting objectives, but often with different details, (e.g. Richards and Huebner in Carbon Manag 3(4):393–410, 2012 and Galik et al. in Mitig Adapt Strateg Glob Change 14:677–690, 2009). The result is that the complexity, expense, and risk of participation discourage participation and make it more difficult to achieve climate mitigation goals. We focus on the requirements for accounting and permanence to illustrate that current requirements disproportionately disadvantage small landowners. Results: The simplified 1040EZ filing system for U.S. income taxes may provide insight for a protocol model that balances reward, effort, and risk, while still achieving the overall objectives of standardized offset protocols. In this paper, we present initial ideas and lay the groundwork behind a "2050EZ" protocol for forest carbon sequestration as a complement to existing protocols. Conclusion: The Paris Agreement states that "Parties should take action to conserve and enhance, as appropriate, sinks and reservoirs of greenhouse gases." The Paris Agreement also refers to issues such as equity, sustainable development, and other non-carbon benefits. The challenge is to provide incentives for maintaining and increasing the amount of carbon sequestered in the biosphere. Monitoring and verification of carbon storage need to be sufficient to demonstrate sequestration from the atmosphere while providing clear incentives and simple accounting approaches that encourage participation by diverse participants, including small land holders.
