Often, individual, communal, regional, or even national conflicts arise when water resources are shared and used. For equitable water-sharing strategies to be implemented, adequate collective action is required to allocate water – not limited to, but specifically in irrigation systems. In this research, we develop an Advanced Irrigation-Related Agent-Based Model (AIRABM) to explore issues of unequal access to water in relation to water use on farm and system levels. By simulating farmer activities and system management decisions within an irrigation system, our research aims to explore farmland dynamics in response to different levels of decision-making according to water availability. We incorporate both individual and collective decision-making processes to explore patterns in farmers’ yields and the dynamics of farmlands. Our results show that (1) within a prevailing trend of increasing yields for higher river discharge and gate capacity, (2) the influence of water availability is characterized by nonlinear changes in yields in response to variations in river discharge and gate capacity, revealing thresholds and tipping points, with (3) strategies for water redistribution partially alleviate inequitable water allocation between upstream and downstream farmers, although considerable variation persists in individual farmers’ and system-wide harvest outcomes. The AIRABM emphasizes individual and collective decision-making processes, encapsulating the uncertainty stemming from water availability and harvests of individual farmers. The modeling framework serves as a valuable tool to explore cooperative approaches in shared (water) resource management. Our findings provide meaningful suggestions to study and promote communication and (conditional) cooperation measures between farmers and management, thereby enhancing the effectiveness of irrigation water distribution., Water Resources

Smallholder farmers (SFs) are cornerstone actors in eradicating poverty and hunger. Companies have recently focused on SFs as potential customers and suppliers. Several hindrances yet prevent SFs to be commercially viable actors. In this respect, sustainable business models (SBMs) bring opportunities for companies to increase profit, improve SFs' livelihoods, and promote environmental sustainability. Recognizing these opportunities, the Dutch company aQysta provides the Barsha pump (BP) as a sustainable irrigation solution for SFs. The challenges for BP adoption that remain for SFs illustrate that there is still limited understanding of how SBMs can support companies in engaging with SFs. To expand this understanding, we conducted a multiple-case analysis of 10 organizations providing SF-tailored products and/or services. Based on this analysis, we have drawn lessons for aQysta (and similar companies) to improve the BP's value proposition and we elaborate on the implications of this study for other organizations engaging commercially with SFs., Water Resources, Design for Sustainability

Recognizing the interrelatedness of water use and conceptual value of IWRM, progressive water resource management systems are moving beyond hierarchical arrangements toward more integrated networks. Increasing calls for participation recognize the value of broadened perspectives that provide both technical expertise as well as social, cultural, and administrative knowledge. Moreover, the call for evidence-based policy of '00s has been tempered by recognition of the political nature of data and science. As such, water decision-makers striving to coproduce and employ shared knowledge must grapple with integrating inputs from diverse participant groups to characterize policy problems and identify effective and feasible solutions. Participatory mandates, coordination bodies, and collaborative networks have emerged to facilitate such integration, and their effective cooperation and alignment relies upon some degree of shared purpose, rather than command and control. But guidance is limited with respect to how to accomplish such integrative aims, including how to support discussions across sectors and silos of practice in order to foster better understanding regarding the problems a policy network collectively aims to address. Motivated by observations within the discourse on water quality in the Brantas River basin in Indonesia, this research explores alternative concepts and problem structures regarding river health via Q methodology. Q methodology, an approach that uses factor analysis to explore human subjectivity, is applied to explore conceptualizations of water quality and the structures of the “water quality problem” in the Brantas. The results show that different groups of perspectives emerge regarding the concept itself, as well as characterization of the current condition of the Brantas. Surprisingly, these variant perspectives do not follow oft-cited government-business-civil society divisions. Moreover, the emergent perspectives demonstrate which aspects of t, Water Resources

On the basis of a data set from four research sites over the course of three agricultural years (2006/2007, 2012/2013, 2016/2017), this article empirically assesses the relations between land tenure security and smallholder farms’ crop production in Rwanda. We show that the general assumption that secure land tenure improves farm level harvests, is not found for smallholder farms in Rwanda. We defined a farmland tenure security index based on plausible threats as conveyed by smallholder farmers at each research site. Our findings indicate that the harvest of main crops did neither statistically correlate with this index, nor show differences from the mean at all research sites. Instead, factors mainly related to the ongoing crop intensification program, though threatening tenure security, contributed to the increase of small farm harvests. Lower land tenure security did not affect farmers satisfaction of the crop program, most of them claiming that in the end what matters most is that their harvests continue to increase. Therefore, in Rwanda, a new wave of agriculture strategizing contributes to increasing small farms’ harvest of prioritized crops and decreasing farm land tenure security simultaneously., Water Resources

Droughts and changing rainfall patterns due to natural climate variability and climate change, threaten the livelihoods of Malawi's smallholder farmers, who constitute 80% of the population. Provision of seasonal climate forecasts (SCFs) is one means to potentially increase the resilience of rainfed farming to drought by informing farmers in their agricultural decisions. Local knowledge can play an important role in improving the value of SCFs, by making the forecast better-suited to the local environment and decision-making. This study explores whether the contextual relevance of the information provided in SCFs can be improved through the integration of farmers’ local knowledge in three districts in central and southern Malawi. A forecast threshold model is established that uses meteorological indicators before the rainy season as predictors of dry conditions during that season. Local knowledge informs our selection of the meteorological indicators as potential predictors. Verification of forecasts made with this model shows that meteorological indicators based on local knowledge have a predictive value for forecasting dry conditions in the rainy season. The forecast skill differs per location, with increased skill in the Southern Highlands climate zone. In addition, the local knowledge indicators show increased predictive value in forecasting locally relevant dry conditions, in comparison to the currently-used El Niño-Southern Oscillation (ENSO) indicators. We argue that the inclusion of local knowledge in the current drought information system of Malawi may improve the SCFs for farmers. We show that it is possible to capture local knowledge using observed station and climate reanalysis data. Our approach could benefit National Meteorological and Hydrological Services in the development of relevant climate services and support drought-risk reduction by humanitarian actors., Water Resources, Transport and Logistics, System Engineering

In the first decade of the 21st century, a water harvesting approach based on contour trenches—ditches to catch runoff—from Kenya was proposed as groundwater recharge technology in a semi-arid area in Ninh Phuoc district, Vietnam. In order to modify this solutions to tackle water scarcity, hydrological conditions at the site needed to be known. For such small-scale interventions, finding the most suitable set of (cheap and quick) efforts to study local hydrology is not easy. After our own study, we explored how different experts evaluated the chosen approach. The results from this evaluation suggest that different perspective for appropriate hydrological research can be found within a group of experts. This finding—in line with anthropologically inspired science studies—suggests that integrating different perspectives from stakeholders when working on suitable solutions in real-life water scarcity situations needs to be complemented with attention for different perspectives on the underlying hydrological processes and how they are to be studied. We discuss how this notion on the multiple perspectives intrinsic to hydrological research can be fruitfully included when developing water interventions., Water Resources

An Advanced Irrigation-Related Agent-Based Model (AIRABM) of farmers' decision-making mechanism and feedback among farmers is developed. The model explores the interactions among human and non-human agents in the irrigation system. In this paper, we discuss harvest patterns as they result from more equal or unequal water distribution in the system. In a baseline model run, farmers are not restricted in their water use. For those situations that yields are low on the system or farmer level, we allow gate settings to be adjusted to improve poor harvest situations. Our model results show that 1) in the baseline scenario, upstream farmers generally receive more water and gain higher yields compared to downstream farmers; 2) gate capacity adjustments of upstream and middle stream farmers can push more water to downstream farmers, but those specific variations are considerable. We observe unexpected emerging system performance. The AIRABM model offers options for how combinations of individual farmers' decisions on water use and farming create (un)equal yield patterns in irrigation systems., Water Resources

Sand dams are impermeable water harvesting structures built to collect and store water within the volume of sediments transported by ephemeral rivers. The artificial sandy aquifer created by the sand dam reduces evaporation losses relative to surface water storage in traditional dams. Recent years have seen a renaissance of studies on sand dams as an effective water scarcity adaptation strategy for drylands. However, many aspects of their functioning and effectiveness are still unclear. Literature reviews have pointed to a range of research gaps that need further scientific attention, such as river corridors and network dynamics, watershed-scale impacts, and interaction with social dynamics. However, the scattered and partially incomplete information across the different reviews would benefit from an integrated framework for directing future research efforts. This paper is a collaborative effort of different research groups active on sand dams and stems from the need to channel future research efforts on this topic in a thorough and coherent way. We synthesize the pivotal research gaps of a) unclear definition of “functioning” sand dams, b) lack of methodologies for watershed-scale analysis, c) neglect of social aspects in sand dam research, and d) underreported impacts of sand dams. We then propose framing future research to better target the synthesized gaps, including using the social-ecological systems framework to better capture the interconnected social and biophysical research gaps on sand dams, fully utilizing the potential of remote sensing in large-scale studies and collecting sand dam cases across the world to create an extensive database to advance evidence-based research on sand dams., Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public., Water Resources

Despite extensive research on farmers’ constraints and decisions, technology developers, policymakers and development organizations still encounter difficulties in relating policies to farmers’ strategies. Often, the concept of ‘smallholders’ is applied as explaining and predicting farmers’ decisions – suggesting that specific strategies of farmers can be meaningfully related to their farm size. Our study into farmers’ decision-making concerning water transport technologies in Malawi suggests that this way of grouping farmers in policy and development programs does not match actual decision strategies. Using Q-methodology (Q) as a method allowed us to find decision-making patterns without predefining variables that would influence decision-making. We found that farmers within a predefined smallholder group did not decide in the same ways. Furthermore, our results show that decision-making has a clear gender dimension. We argue that Q is able to capture the nuances of farmers’ decision-making processes. As such, the methodology potentially provides a useful feed for policy and technology development., Sanitary Engineering, Water Resources, Design for Sustainability

Improved water management is an important strategy to support smallholder farming, and thus to foster food security and improved livelihoods. Within this strategy, technologies like water pumps, especially those operating on renewable energies, are key, as they are more environmentally sound and affordable alternatives. Their successful and sustained uptake is a complex process—largely dependent on the adopter and its surrounding context—usually overlooked by traditional linear technology-transfer approaches. By means of Q methodology, we explored cross-cultural discourses around the adoption of the Barsha pump (BP), a self-reliant hydro-mechanical device that does not require any external input than flowing water to operate. We administered the method to 43 (non-)farmer respondents linked to Nepali and Indonesian smallholder farming systems. We identified three relevant discourses, one of them bipolar in nature. These three groups accounted for 39, 36, and 28% of the total explained variance of our study. The first one identified BP's potential early adopters. The second discourse embodied the (stereotypical) highly dependent smallholder. The last one characterized (contrasting) views around the BP as an enabler of potential service-oriented business models to achieve wellbeing. These results reflect the need for a shift of mindset toward new ways of understanding technological change in smallholder settings. On the one side, simplistic one-size-fits-all models cannot connect to the diversity of issues and opinions as we found. On the other side, it is virtually impossible to produce tailored solutions to satisfy each of those individual realities. We propose possible adoption pathways that may lead to the exploration of innovative and adaptable business models that serve the diversity of smallholder farming needs more effectively., Water Resources, Design for Sustainability

The literature on irrigated agriculture is primarily concerned with irrigation techniques, irrigation water-use efficiency, and crop yields. How human and non-human agents co-shape(d) irrigation landscapes through their activities and how these actions impact long-term developments are less well studied. In this study, we aim to (1) explore interactions between human and non-human agents in an irrigation system; (2) model the realistic operation of an irrigation system in an agent-based model environment, and; (3) study how short-term irrigation management actions create long-term irrigation system patterns. An agent-based model (ABM) was used to build our Irrigation-Related Agent-Based Model (IRABM). We implemented various scenarios, combining different irrigation control methods (time versus water demand), different river discharges, varied gate capacities, and several water allocation strategies. These scenarios result in different yields, which we analyse on the levels of individual farmer, canal, and system. Demand control gives better yields under conditions of sufficient water availability, whereas time control copes better with water deficiency. As expected, barley (Hordeum vulgare, Poaceae) yields generally increase when irrigation time and/or river discharge increase. The effect of gate capacity is visible with yields not changing linearly with changing gate capacities, but showing threshold behaviour. With the findings and analysis, we conclude that IRABM provides a new perspective on modelling the human-water system, as non-human model agents can create the dynamics that realistic irrigation systems show as well. Moreover, this type of modelling approach has a large potential to be theoretically and empirically used to explore the interactions between irrigation-related agents and understand how these interactions create water and yields patterns.

Emerging societal complexity is closely linked to water systems within archaeology. When studying water-based societies, climate is usually conceptualized as an external force. Such an perspective risks missing how societal agents change both meaning and effects of climatic changes. This chapter proposes to develop an model-approach based on continuous interactions between humans and landscapes. The examples come from three case studies outside the Roman world: the Hohokam (500–1500 AD, current Arizona), the Zerqa Triangle, Jordan, during the Late Bronze Age (c. 1300–1100 BC), and the Maya city of Tikal (250 AD–900 AD, current Guatemala). The ideas that can be developed through these cases are compared to conceptualizations from recent publications discussing modelling of/in the Roman world. In general, this chapter argues that larger-scale and longer-term correlations have to be explained in terms of causalities between short-term agencies., Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public., Water Resources

De in 2019 verschenen publicatie Broek en Waterland. Regionale samenwerking en conflicten, 1281-1811 maakt door een gedetailleerde weergave van discussies tussen de Waterlanders, de baljuw en Amsterdam duidelijk dat Broek in Waterland en de collega-dorpen continu bezig waren met het realiseren van invloed en het behalen van doelen door onderhandelingen. Tevens blijkt uit het boek dat de materiële omgeving die het gevolg was van de onderhandelingen ook de nodige invloed uitoefende op die onderhandelingen. De invloed van menselijke betrokkenen werd gerealiseerd via niet-menselijke historische actoren, zoals geld, hout of aarde – met uiteraard het water in een grote rol. De waterinfrastructuur van de regio was een belangrijke drager van de macht die dorpen en steden konden ontwikkelen. De macht van het waterschap bleek relatief te zijn, omdat het waterschap slechts een van de invloedrijke bestuursapparaten was. Bestuurlijke functies en rollen in Waterland bleken bovendien goed te combineren, zodat leden van een dorps- of stadsbestuur regelmatig ook in het waterschapsbestuur optraden. Deze verwevenheid van bestuursfuncties problematiseert het te vanzelfsprekende beeld van zelfstandige waterschappen met veel macht en weinig bestuurlijke overlap in de Nederlandse waterstaatsgeschiedenis., Water Resources

This text builds on the shared focus of historians and engineers to understand how particular circumstances came to be. In their endeavours, engineers regularly turn attention to the past, many times with the explicit aim to build on the past. In this chapter, it is discussed why these water histories written by engineers are vulnerable to being less correct. Using a range of scholarship on water history and shared experiences within the International Water History Association, we discuss the core of any historical scholarship: a drive to demonstrate and understand the complexity of the past. As such, this chapter wants to warn against the engineering drive to use (water) history as a guide towards the future. Instead, we propose a perspective of history as a way of reading and understanding the complex paths we have travelled until now., Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public., Water Resources

This paper assesses the success of sand-storage dams in Kitui, Kenya—with “success” being considered to relate to the amount of water that dams can store, and the usability of the water in terms of access, quantity and quality. Building on a series of recent larger and smaller research projects, the paper sketches the complex interactions between community involvement, water use, and hydrological processes. Catchment-wide processes (including infiltration and runoff) resulting in water retention and sustained flow in the seasonal rives need to be taken into account. At the same time, within a catchment and within communities, diversity between water users (for example in terms of access or values related to water) will be encountered. The interplays between all these different issues have to be studied in more detail, to support governments and communities developing water harvesting interventions like sand-storage dams., Water Resources

In Kenya, where 80% of the land is arid and semi-arid, access to water is an everyday challenge for majority of the people. Methods used to improve access to water in Kenya results to different, and sometimes unexpected outcomes. The water resources assessed have come about through interventions by various agents, majority donor funded. These agents use various models resulting to different outcomes. We assessed technologies used to improve access to water in the Asals of Kitui County, Kenya. The technologies were classified into four; individual, private, community and government owned. Those assessed were tanks, boreholes and hand dug wells, sand dams and pipelines for individual, private, community and government owned respectively. Private and individual resources outperformed others in terms of management with donor aided community owned being the least sustainable. Government owned water facilities reached relatively more people and although unreliable were the most trusted source to those covered by the infrastructure. Individual owned water resources offered water in small quantities, the main benefit being owners were able to manage with ease through rationing to stretch availability for a long time. Donor funded community owned resources suffered vague ownership models making their management and maintenance impossible. Privately owned resources offered the best solution as water was sold and the resulting money become income for the owners as well as providing resources for maintenance. The resulting income offered incentives for further investment which further improved access. The tragedy with privately owned water resources was that the poor paid too much for water while the rich continued to accumulate massive wealth. To ensure adequate access to water especially in remote places, privately owned and operated systems should be encouraged and supported but with government sponsored regulations to ensure the poor are not exploited., Water Resources

Reduction of poverty is a main goal in the global development agenda. The most extreme forms of poverty are mainly rooted in the Global South, and even more engrained in its rurality. Such poverty is not only characterized by infimum incomes, but also by the lack of access to many resources and services: health, sanitation, drinking water, education, etc. Eradication of deep poverty therefore demands a holistic understanding of its causes, as well as the wicked interaction of its many variables. International definitions of (deep) poverty, however, keep resorting to income thresholds (e.g. World Bank’s International Poverty Line) to measure it. In consequence, such definitions may overshadow underlying context-dependent complexities: gender dimensions, urban/rural divide, societal power relationships, local economic dynamics. Q methodology is a potentially powerful tool to understand better the different nuances of poverty, thus to enable a more effective tackling of its roots. First, as a participatory method, it offers voices to grassroots participants to express their own priorities and concerns. Second, it encompasses rich qualitative data that go beyond oversimplified quantitative thresholds and analyses. Third, as a reductionist technique, it condenses (virtually) infinite positions into clearly identifiable poverty discourses. At the same time, methodological deployment of Q methodology in low-resource settings, and particularly in rural areas, poses several (underreported) challenges worth to be considered and discussed. These challenges may be exacerbated in light of big shocks, like the current COVID-19 pandemic.

Smallholder farming is a backbone of millions of livelihoods in the Global South. It provides up to 80% of the food demanded in Sub-Saharan Africa and Asia while scarcely occupying 12% of the global farmland. About 1.5 billion deeply poor households—especially those located in rural areas—depend directly on smallholder agriculture. Stimulating its sustainable intensification is thus of utmost importance in the fulfilment of SDG 2: Zero Hunger and SDG 1: No poverty. Despite decades of (top-down) scientific research, technology transfer and international aid, effective development of this sector remains a summit hard to reach. Profound heterogeneity of smallholder farming systems exacerbates the challenges of this endeavor. Their intricate differences does not only make a single, ultimate development model impractical/impossible, but ignoring them leads us to biases that result in leaving the most disadvantaged out. We argue that well facilitated participatory research is a sounder way to understand, and hence to act. First, it enables a bottom-up, co-creative process of mutual generation of knowledge together with relevant stakeholders. Second, it gives voice to the (generally) voiceless, therefore turning into a more inclusive and empowering exercise. We resorted to Q-methodology—a powerful qualiquantological participatory method—to explore smallholder adoption of sustainable irrigation technologies in Nepal and Indonesia. We interviewed 19 farmers and 24 experts about the uptake of a hydro-powered water pump commercially known as the Barsha pump. Through this research technique, we found three different viewpoints that placed themselves beyond typical social constructs of smallholder farming (e.g. country, land size). This deeper understanding may become an enabler for a more context-sensitive transfer of farming technology. On the flipside, the implementation of Q methodology in low-resource (rural) settings still poses a number of underreported challenge, Water Resources, Design for Sustainability

Smallholder farming is the cornerstone of the agricultural sector in the Global South. It produces 80% of the food in Sub-Saharan Africa and Asia, though it accounts for barely 12% of the global farmland. Its sustainable intensification is therefore paramount in the accomplishment of Sustainable Development Goal 2: Zero Hunger. In this respect, adoption of sustainable water pumping technologies is key to ensure access to irrigation water, thus to secure smallholder production. Sustained uptake of agricultural technologies, however, is a complex process whose attainment is far beyond the sole technology itself. It encompasses a number of intertwined variables of all kinds related to the adopter and the use context: biophysical, financial, institutional, social, cultural, etc. We argue that innovative business models—like sustainable product-service system (SPSS)—have the potential to ease the adoption process by overcoming many of its constraints (e.g. unaffordable upfront costs, lack of adequate servicing). These business models, unlike traditional linear approaches of technology transfer, have to take into account a broader network of stakeholders. In this way, the technology becomes an agent of interaction between involved parties. It turns into a dynamic element, connected to other products and well-developed services, that caters multiple farming needs. In our paper, we discuss enablers and barriers for the implementation of an SPSS in smallholder contexts under different scenarios. We analyze them based on evidence from Nepali and Indonesian smallholder communities where a novel hydro-powered pumping technology, known commercially as the Barsha pump, has been deployed. The insights gathered reveal many leverage points to create synergies between farmers, entrepreneurs, financial institutions, non-profit organizations and governmental agencies. They also denote the persistent challenges in the required shift of mindset for such an innovative system to c, Water Resources, Design for Sustainability

In order to explore possibilities of mimicking the operation of an irrigation system under varied scenarios, the authors have designed the Irrigation-Related Agent-Based Model (IRABM), providing a platform for integrating human and non-human agents (water managers, farmers, barley, river, canals, and gates) together and analyzing the interactions among these agents. IRABM illustrates how barley yields respond to varied irrigation strategies and how patterns of yields vary among the levels of individual farmers, canals, and the whole irrigation system. The model proves how this type of theoretically and empirically informed computer model can be used to develop new insights into studying and simulating interactions between individuals and their environment in an irrigation system. Furthermore, it demonstrates how and why irrigation and yield patterns can emerge from changing actions. One of the applications of the model will be for ancient Southern Mesopotamia, the pluvial land between the two rivers Euphrates and Tigris. Our knowledge of irrigation management and irrigated-landscapes in southern Mesopotamia fairly scant due to lack of data, but also because attention for the details of irrigation management has been ignored in archaeological analysis to date. IRABM offers options to synchronize the general features of irrigation systems to the specifics of Mesopotamia. How to represent ancient Mesopotamia in IRABM is the key question we address in this paper. Given the low precipitation, the available water in Mesopotamia’s watercourses for cultivation was vital. This prompted the establishment of irrigated agriculture, leading to its sophisticated irrigation systems over time. Management of irrigation activities is both related to water volumes in the different (levels of) water courses, and to the size of a system. Because of the expanding Mesopotamian society, and this its irrigated areas, the unpredictable water availability, and the threat of, Water Resources

These challenges may be exacerbated in light of big shocks, like the current COVID-19 pandemic. Whether related to the concourse development, sorting grid design, P-set sampling, administration, data recording or validation, researchers may encounter a number of concerns/restrictions. In our work, we analyze these challenges along with proposed corresponding best practices.

De in 2019 verschenen publicatie Broek en Waterland. Regionale samenwerking en conflicten, 1281-1811 maakt door een gedetailleerde weergave van discussies tussen de Waterlanders, de baljuw en Amsterdam duidelijk dat Broek in Waterland en de collega-dorpen continu bezig waren met het realiseren van invloed en het behalen van doelen door onderhandelingen. Tevens blijkt uit het boek dat de materiële omgeving die het gevolg was van de onderhandelingen ook de nodige invloed uitoefende op die onderhandelingen. De invloed van menselijke betrokkenen werd gerealiseerd via niet-menselijke historische actoren, zoals geld, hout of aarde – met uiteraard het water in een grote rol. De waterinfrastructuur van de regio was een belangrijke drager van de macht die dorpen en steden konden ontwikkelen. De macht van het waterschap bleek relatief te zijn, omdat het waterschap slechts een van de invloedrijke bestuursapparaten was. Bestuurlijke functies en rollen in Waterland bleken bovendien goed te combineren, zodat leden van een dorps- of stadsbestuur regelmatig ook in het waterschapsbestuur optraden. Deze verwevenheid van bestuursfuncties problematiseert het te vanzelfsprekende beeld van zelfstandige waterschappen met veel macht en weinig bestuurlijke overlap in de Nederlandse waterstaatsgeschiedenis., Water Resources

In Kenya, where 80% of the land is arid and semi-arid, access to water is an everyday challenge for majority of the people. Methods used to improve access to water in Kenya results to different, and sometimes unexpected outcomes. The water resources assessed have come about through interventions by various agents, majority donor funded. These agents use various models resulting to different outcomes. We assessed technologies used to improve access to water in the Asals of Kitui County, Kenya. The technologies were classified into four; individual, private, community and government owned. Those assessed were tanks, boreholes and hand dug wells, sand dams and pipelines for individual, private, community and government owned respectively. Private and individual resources outperformed others in terms of management with donor aided community owned being the least sustainable. Government owned water facilities reached relatively more people and although unreliable were the most trusted source to those covered by the infrastructure. Individual owned water resources offered water in small quantities, the main benefit being owners were able to manage with ease through rationing to stretch availability for a long time. Donor funded community owned resources suffered vague ownership models making their management and maintenance impossible. Privately owned resources offered the best solution as water was sold and the resulting money become income for the owners as well as providing resources for maintenance. The resulting income offered incentives for further investment which further improved access. The tragedy with privately owned water resources was that the poor paid too much for water while the rich continued to accumulate massive wealth. To ensure adequate access to water especially in remote places, privately owned and operated systems should be encouraged and supported but with government sponsored regulations to ensure the poor are not exploited., Water Resources

This text builds on the shared focus of historians and engineers to understand how particular circumstances came to be. In their endeavours, engineers regularly turn attention to the past, many times with the explicit aim to build on the past. In this chapter, it is discussed why these water histories written by engineers are vulnerable to being less correct. Using a range of scholarship on water history and shared experiences within the International Water History Association, we discuss the core of any historical scholarship: a drive to demonstrate and understand the complexity of the past. As such, this chapter wants to warn against the engineering drive to use (water) history as a guide towards the future. Instead, we propose a perspective of history as a way of reading and understanding the complex paths we have travelled until now., Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public., Water Resources

This paper assesses the success of sand-storage dams in Kitui, Kenya—with “success” being considered to relate to the amount of water that dams can store, and the usability of the water in terms of access, quantity and quality. Building on a series of recent larger and smaller research projects, the paper sketches the complex interactions between community involvement, water use, and hydrological processes. Catchment-wide processes (including infiltration and runoff) resulting in water retention and sustained flow in the seasonal rives need to be taken into account. At the same time, within a catchment and within communities, diversity between water users (for example in terms of access or values related to water) will be encountered. The interplays between all these different issues have to be studied in more detail, to support governments and communities developing water harvesting interventions like sand-storage dams., Water Resources

Smallholder farming is a backbone of millions of livelihoods in the Global South. It provides up to 80% of the food demanded in Sub-Saharan Africa and Asia while scarcely occupying 12% of the global farmland. About 1.5 billion deeply poor households—especially those located in rural areas—depend directly on smallholder agriculture. Stimulating its sustainable intensification is thus of utmost importance in the fulfilment of SDG 2: Zero Hunger and SDG 1: No poverty. Despite decades of (top-down) scientific research, technology transfer and international aid, effective development of this sector remains a summit hard to reach. Profound heterogeneity of smallholder farming systems exacerbates the challenges of this endeavor. Their intricate differences does not only make a single, ultimate development model impractical/impossible, but ignoring them leads us to biases that result in leaving the most disadvantaged out. We argue that well facilitated participatory research is a sounder way to understand, and hence to act. First, it enables a bottom-up, co-creative process of mutual generation of knowledge together with relevant stakeholders. Second, it gives voice to the (generally) voiceless, therefore turning into a more inclusive and empowering exercise. We resorted to Q-methodology—a powerful qualiquantological participatory method—to explore smallholder adoption of sustainable irrigation technologies in Nepal and Indonesia. We interviewed 19 farmers and 24 experts about the uptake of a hydro-powered water pump commercially known as the Barsha pump. Through this research technique, we found three different viewpoints that placed themselves beyond typical social constructs of smallholder farming (e.g. country, land size). This deeper understanding may become an enabler for a more context-sensitive transfer of farming technology. On the flipside, the implementation of Q methodology in low-resource (rural) settings still poses a number of underreported challenge, Water Resources, Design for Sustainability
