Addressing conflict through collective action in natural resource management: A synthesis of experience
(Working Paper, 2013) Ratner, Blake D.; Meinzen-Dick, Ruth S.; Hellin, Jonathan; Mapedza, Everisto; Unruh, Jon D.; Veening, Wouter; Haglund, Eric; May, Candace; Bruch, Carl
The food security crisis, international “land grabs,” and new markets for environmental services have drawn renewed attention to the role of natural resource competition in the livelihoods of the rural poor. While significant empirical research has focused on diagnosing the links between natural resource competition and (violent) conflict, much less has focused on the dynamics of whether and how resource competition can be transformed to strengthen social-ecological resilience and mitigate conflict. Focusing on this latter theme, this review synthesizes evidence from a wide range of cases in Africa, Asia, and Latin America. Building on an analytical framework designed to enable such comparative analysis; we present several propositions about the dynamics of conflict and collective action in natural resource management, and a series of recommendations for action.
Why did Mozambique’s public extension halt the implementation of the National Agrarian Extension Program (PRONEA)?
(Brief, 2013) Gêmo, Hélder; Chilonda, Pius
This paper assesses critical factors that constrained the successful implementation of the National Agrarian Extension Program, (PRONEA, from Programa Nacional de Extensão Agrária), by MINAG’s National Directorate of Agrarian Extension (DNEA, from Direcção Nacional de Extensão Agrária), which resulted in a decision to halt PRONEA in 2010, three years after its launch. A conceptual framework for planning and implementing programs and strengthening pluralistic agricultural extension and advisory systems identified factors that should ideally have been taken into account before launching PRONEA in order to reduce the risk of failure. The analysis was based on a review of the literature about agricultural extension in Mozambique, official documents, interviews with key informants and experts, and field visits to various provinces.
Exploring strategic priorities for regional agricultural research and development investments in southern Africa
(Working Paper, 2014) Johnson, Michael E.; Benin, Samuel; You, Liangzhi; Diao, Xinshen; Chilonda, Pius; Kennedy, Adam
An in-depth quantitative analysis is undertaken in this paper to assist the Southern African Development Community (SADC) Secretariat, member countries, and development partners in setting future regional investment priorities for agricultural research and development in the SADC region. A primary goal of this work was to identify a range of agricultural research priorities for achieving sector productivity and overall economic growth in southern Africa, at both the country and regional levels. This is accomplished by adopting an integrated modeling framework that combines a disaggregated spatial analytical model with an economywide multimarket model developed specifically for the region.
Rural finance and agricultural technology adoption in Ethiopia: Does institutional design matter?
(Working Paper, 2015-03-06) Abate, Gashaw T.; Rashid, Shahidur; Borzaga, Carlos; Getnet, Kindie
Financial cooperatives and microfinance institutions (MFIs) are the two major sources of rural finance in Ethiopia. Whereas MFIs are relatively new, financial cooperatives have existed for centuries in various forms. The coexistence of two different institutions serving the same group of people, and delivering the same financial services, raises several policy questions. Those questions have become particularly relevant, as the government has embarked on developing a new strategy for improving rural financial services delivery. This study is expected to serve as an input to that policy discussion. Using a unique household survey dataset and the propensity-score-matching technique, we examine the impacts of the two financial service providers on agricultural technology adoption. The results suggest that access to institutional finance has significant positive impacts on both the adoption and extent of technology use.
A framework for an African Water Quality Program (AWaQ)
(Working Paper, 2024-05-28) Mukuyu, Patience; Dickens, Chris; Jayathilake, Nilanthi; Tijani, M.; Chapman, D. V.; Warner, S.
The African Ministers’ Council on Water (AMCOW) Secretariat committed to design and implement an African Water Quality Program (AWaQ) in its Strategic Operational Plan (2020-2024) considering the guiding frameworks is uses such as the Africa Water Vision 2025, United Nations Sustainable Development Goals (SDGs), and the African Union Agenda 2063: The Africa We Want. AMCOW reached out to the International Water Management Institute (IWMI) to support the development of such a program. AWaQ builds on the rich experiences and lessons learned from past and ongoing regional and subregional water quality initiatives across Africa by different players, including African Union institutions, and the wider members of the World Water Quality Alliance (WWQA), as well as the AMCOW African Water and Sanitation Sector Monitoring and Reporting System (WASSMO). The five phases of developing an African Water Quality Program (AWaQ) are explained in the following papers: 1. State of Water Quality Monitoring and Pollution Control in Africa (phase 1-2) 2. Innovations in Water Quality Monitoring and Management in Africa (phase 3-4) 3. A Framework for an African Water Quality Program (AWaQ) (phase 5) 4. Country Water Quality Profiles This paper is the third in the above list and is the culmination of the development of AWaQ. It provides a foundational structure for developing a framework for AWaQ and is guided by the three principles of state custodianship, co-development, and coordination and collaboration. It has been proposed that AMCOW Member States will retain their sovereignty and become custodians of the data and information generated as part of AWaQ, and will be closely involved in the development of program activities. Further, AWaQ entails coordination and collaboration between regional, global and transboundary institutions and initiatives involved in water quality monitoring, assessment and management. The framework for AWaQ rests on the following four core components which were developed based on stakeholder consultations and literature studies: 1. Governance 2. Water quality monitoring 3. Data management 4. Capacity building AWaQ will aim to deliver within each of these core components. The governance component of AWaQ will build on already existing country governance structures and regulatory provisions through management approaches such as Integrated Water Resources Management and Catchment-based Water Management, with the aim of achieving the goal of improved water quality. The water quality monitoring component will aim to encourage countries to collect basic water quality data to support regional and global indicators. The data management component will make use of decentralized national platforms, where countries submit only final national assessments to AMCOW for reporting and planning while retaining the raw data on their own databases. Lastly, the capacity building component would be coordinated through AMCOW to deliver standardized and tailor-made training to Member States with support from global donors. Development of this framework needs to be followed by a strategic implementation plan that would provide a road map for implementing AWaQ. The strategic implementation plan would involve a series of steps, including stakeholder mapping, clarified roles and responsibilities, budgets, key indicators and associated monitoring programs, and overall coordination and reporting mechanisms. Specific activities under each core component of the framework need to be designed to meet the objectives of AWaQ. This paper only goes as far as providing the overall framework for AWaQ.
Innovations in water quality monitoring and management in Africa: towards developing an African Water Quality Program (AWaQ)
(Working Paper, 2024-05-28) Mukuyu, Patience; Warner, S.; Chapman, D. V.; Jayathilake, Nilanthi; Dickens, Chris; Mateo-Sagasta, Javier
The African Ministers’ Council on Water (AMCOW) Secretariat committed to design and implement an African Water Quality Program (AWaQ) in its Strategic Operational Plan (2020-2024) considering the guiding frameworks it uses such as the Africa Water Vision 2025, United Nations Sustainable Development Goals (SDGs), and the African Union Agenda 2063: The Africa We Want. AMCOW reached out to the International Water Management Institute (IWMI) to support the development of such a program. AWaQ builds on the rich experiences and lessons learned from past and ongoing regional and subregional water quality initiatives across Africa by different players, including African Union institutions, and the wider members of the World Water Quality Alliance (WWQA), as well as the AMCOW African Water and Sanitation Sector Monitoring and Reporting System (WASSMO). The five phases of developing an African Water Quality Program (AWaQ) are explained in the following papers: 1. State of Water Quality Monitoring and Pollution Control in Africa (phase 1-2) 2. Innovations in Water Quality Monitoring and Management in Africa (phase 3-4) 3. A Framework for an African Water Quality Program (AWaQ) (phase 5) 4. Country Water Quality Profiles This paper is the second in the above list and documents the greatest innovations in water quality monitoring and management in Africa, and proposes interventions to strengthen Africa’s current water quality monitoring and management efforts. Innovations related to monitoring program design, analytical techniques and instruments, deployment of instrumentation and approaches to water quality monitoring are presented together with their applicability and suitability for implementation in Africa. Similarly, water quality management interventions — policy and regulatory mechanisms, catchment-based management, data management and sharing, wastewater reuse and nature-based solutions, among others — are examined. The most suitable interventions are proposed for African contexts using criteria such as affordability, scalability and flexibility. Key findings of this paper highlight the following: 1. There are numerous innovations within water quality monitoring and management. However, not all of them may be suitable for implementation in resource-constrained environments characteristic of many parts of Africa. For example, statistical analysis and modelling may require large amounts of existing monitoring data currently unavailable in most African countries. Nonetheless, other interventions such as the priority monitoring approach can be beneficial in optimizing resource utilization. Similarly, technological interventions such as multi-parameter sensors for basic water quality variables are now widely available and affordable in the provision of in situ results and lessening the need for laboratory analysis. 2. Available and existing traditional methods of water quality monitoring and management offer a good starting point to further strengthen and streamline efforts for increasing efficiency and effectiveness. Currently available laboratory facilities may benefit from instrumentation upgrades and continuous staff training. 3. There is scope for community and citizen engagement in the various processes of water resources monitoring and management. There is evidence that this enables success where governments do not have the monitoring capacity or adequate resources.
State of water quality monitoring and pollution control in Africa: towards developing an African Water Quality Program (AWaQ)
(Working Paper, 2024-05-27) Mukuyu, Patience; Jayathilake, Nilanthi; Tijani, M.; Nikiema, Josiane; Dickens, Chris; Mateo-Sagasta, Javier; Chapman, D. V.; Warner, S.
The African Ministers’ Council on Water (AMCOW) Secretariat committed to design and implement an African Water Quality Program (AWaQ) in its Strategic Operational Plan (2020-2024) considering the guiding frameworks it uses such as the Africa Water Vision 2025, United Nations Sustainable Development Goals (SDGs), and the African Union Agenda 2063: The Africa We Want.

The five phases of developing an African Water Quality Program (AWaQ) are explained in the following papers: 1. State of Water Quality Monitoring and Pollution Control in Africa (phase 1-2) 2. Innovations in Water Quality Monitoring and Management in Africa (phase 3-4) 3. A Framework for an African Water Quality Program (AWaQ) (phase 5) 4. Country Water Quality Profiles This paper is the first from the above list and is a baseline assessment of the status of water quality monitoring and pollution control in Africa, including the capacities available across countries in the region. This assessment considers various past and ongoing initiatives related to water quality monitoring and management, capacity development, and water pollution control and impact mitigation. Key findings of this paper highlight the following: 1. There is an encouraging availability of national water testing laboratory facilities across African countries. Nonetheless, there are weaknesses that require attention to ensure effectiveness and sustainability. 2. Regular and ongoing training is needed to keep up with laboratory testing methodologies. However, we observed a low trend in regular training, which does not augur well for keeping abreast of the best practices in water quality monitoring. In the context of emerging pollutants, training needs to be more regular than is currently experienced. 3. Water quality monitoring and management capacities are patchy. Capacities related to staff training, laboratory infrastructure and monitoring program activities need strengthening. 4. Pollution control mechanisms are facing challenges. Regulatory mechanisms and wastewater treatment technologies—the most widely deployed pollution control solutions—may benefit from more concerted investment, and the political will and financing to boost their effectiveness.
Investment and cultivation strategies for women and youth inclusion: cases from on-farm, off-farm and non-farm activities in Ethiopia and Mali
(Working Paper, 2024-05-08) Nigussie, Likimyelesh; Diallo, A.; Minh, Thai Thi
Africa's agriculture sector is vital for food security, employment, and economic growth. Women and young people, who contribute to innovation, diversification, and income, face limited opportunities in the sector due to social and economic power imbalances. This disparity wastes resources and impedes agricultural value chain development (VCD). Inclusive VCD aims to empower women, men and youth from diverse social groups and strengthen the agriculture sector. However, the literature on inclusive VCD in Africa is limited due to urban biases, and the lack of a framework to address gender inequality and poverty. This study explores how livelihood assets, strategies for accessing the assets, and enabling and discouraging factors in the value chain shapes the inclusion of women and youth in on-farm, off-farm and non-farm activities. It is based on the Safeguarding Sahelian Wetlands for Food Security (SaWeL) program that aims to make the market work for the poor through inclusive VCD in the Ziway-Shalla Sub-basin of Ethiopia, and Wegnia and Sourou basins in Mali. A qualitative dataset of 32 focus group discussions, 48 key informant interviews and 40 in-depth interviews were analyzed. We identified investment and cultivation inclusion strategies that demonstrates how women and youth from diverse social groups actualize business opportunities, overcome challenges and create new opportunities for inclusion. Investment strategies involve women and youth from better-off households with good access to natural, social, political and physical capital for capital-intensive roles. On the other hand, cultivation strategies involve women and youth from resource-poor households who can harness natural, social and political capital to participate in off-farm and non-farm activities. Our results show that women and youth who adopt either one of the strategies are encouraged by good support from social networks, cooperatives, Government Organizations, Nongovernmental Organizations and private sector actors. However, access to productive resources and services for women and youth adopting any strategies is hampered by gender and intergenerational norms, poverty and insufficient institutional capacity. We argue that it is essential to understand how social disparities and local environments interact to inform the design and implementation of inclusive value chains. Additionally, inclusive value chains necessitate building capacities of institutions at different scales.
Opportunities for and constraints to safe and sustainable vegetable production in Sri Lanka
(Working Paper, 2023-12-31) Aheeyar, Mohamed; Jayathilake, Nilanthi; Kumara, G. D. K.; Wijetunga, C. S.; Madhuwanthi, Piumi; Duleesha, Nisansala
Sri Lanka is blessed with ideal conditions for cultivating a wide variety of fruits and vegetables. The country has around 80 varieties produced in different agroecological zones. There are several government and private organizations supporting vegetable farmers and farmers are organized into formally registered organizations. However, the average consumption of fruits and vegetables in Sri Lanka is around 150 g per day and per capita consumption is approximately 112 g per day, which is 50% lower than the World Health Organization (WHO) recommendations (SAARC 2017). For a healthy and prosperous nation, the production and consumption of fruits and vegetables are important. Our research set out to identify opportunities and barriers for sustainable and year-round vegetable production. The findings are based on two multistakeholder consultations, a gendered field survey conducted in 18 villages through separate women and men focus group discussions (FGDs), key informant interviews in Welimada and Balangoda Divisional Secretariat Divisions, and a comprehensive literature review. The study focused on upcountry temperate zone vegetables.
The political economy of land-water resource governance in the context of food security in Cambodia
(Working Paper, 2023-11-07) Öjendal, J.; Monin, N.; Chanmony, S.; Sidana, B. Z.; Chanrith, N.
Water is central for a variety of livelihoods, development, economic growth, and food production. It is also very important in the large deltas of South and Southeast Asia. Yet, water is turning into a scare resource and global climate change is making its availability more unpredictable. Commercial interests and infrastructure development are also competing for water resources, sometimes at the expense of local smallholders. This report, which is a desk study combined with stakeholder interviews, aims to map out the issues and the previously unknown challenges to efficient water and land management for poverty alleviation and food security. It also serves as a basis for an empirical case study on the same topic. The report illuminates the political economy of land-water resources in the floodplains around the Tonle Sap Lake which constitutes the upper part of the Mekong River Delta and shares seasonal fluctuations and livelihood patterns. The report identifies key challenges for land-water integrity and multi-functionality in food security, nutrition and income impacts for different local producers. The versatile delta landscape and its livelihoods are a complex ecosystem; the driving factors include seasonal water flow variations, the construction of upper Mekong dams, climate change, and the minimal regulations of local resource governance. This evidently makes the governance challenge both immense and urgent. This report maps out opportunities from national to local levels for promoting more systematic, productive and inclusive land-water management. The roles of formal and informal actors within political spaces, their influence on policy and practice, and opportunities to influence these actors are of particular interest. In pursuing the above, the report applies a political economy approach, where the role of the state, its policies and resource allocation are in focus. This also includes the presence of politically and commercially vested interests and how civil society is involved in the general strife for food security and poverty alleviation. The political economy approach constitutes a holistic analysis of how a society is governed and who possesses and utilises which power in order to pursue their interests. At the core of the political economy approach is therefore the illumination of power (and powerlessness) through analysis of actors or a group of actors and their particular interests. The empirical realms in this report focus on contemporary resource management, its institutions and actors.
Anticipatory action in communities hosting refugees and internally displaced persons: an assessment of current approaches
(Working Paper, 2023-12-31) Schindler, Alexandra; Singh, Radhika; Adam-Bradford, A.; Laauwen, M.; Ruckstuhl, Sandra
This paper is a global literature review of anticipatory action approaches in communities hosting forcibly displaced persons. Anticipatory action, or a set of actions taken to prevent or mitigate a potential disaster before acute impacts are felt, is an essential strategy to reduce the impacts of climate change and extreme weather events. However, due to the complexity and diversity of host community environments, it has proven challenging to incorporate this approach into these contexts. This paper provides a review of the available data on water- and climate-related vulnerabilities in host communities to inform and strengthen anticipatory action approaches and climate adaptation initiatives. It also supports future research for the development of a replicable and scalable mixed-methods model called the Integrated Host Community Vulnerability Framework (IHCVF). This paper starts with a background and technical overview of anticipatory action as it is currently implemented by humanitarian and development organizations. This overview highlights the lack of research on how anticipatory action can take into account the specific vulnerabilities of host communities. The paper then provides a detailed definition of host communities, a term the authors use to refer to the context, institutions and structures within which forcibly displaced persons live, and encompasses both the hosts and the displaced. Finally, it reviews the early stages of development of the IHCVF, including operational needs, specific vulnerabilities to consider, and current gaps in the field that need to be covered with future research. Next, the paper analyzes the types of water- and climate-related vulnerabilities in host communities, and the anticipatory action approaches that organizations are undertaking in those communities, using case studies from Bangladesh, Nigeria and Sahel. The data from these case studies show how existing host community vulnerabilities and food, land and water-related stresses can compound disasters for hosts and forcibly displaced people when impacted by extreme weather events, conflict, disease outbreaks, and food insecurity. Finally, this paper ends with a few conclusions about gaps in the data, including a lack of anticipatory action strategies that prioritize long-term outcomes such as resilience building and adaptation, and the need for guidance on how to better implement anticipatory action and forecast-based humanitarian action in conflict situations. It recommends further research on water- and climate-related vulnerabilities in communities hosting forcibly displaced people to provide practical guidance to inform future programming.
Enabling environment and digital technology use readiness in agriculture in the Zambezi riparian countries
(Working Paper, 2023-12-31) Matchaya, Greenwell C.; Malambo, M.; Mayoyo, A.
This study sought to understand the extent of digital technology usage across Zambezi riparian countries and analyze whether there is a conducive enabling environment for digital technology upscaling for climate adaptation. The study thus, examined the relationship between having a better enabling environment and the use of digital technologies in agriculture. Using data collected through stakeholder consultations in Malawi, Mozambique, Zambia and Zimbabwe as well desk studies focusing on the rest of the Zambezi riparian countries (Angola, Botswana, Malawi, Mozambique, Namibia, Tanzania, Zambia and Zimbabwe, the study finds that having an enabling environment for the upscaling of digital technologies varies from one Zambezi riparian country to the other, with Botswana and Namibia, having a better enabling environment and, thus a better readiness for digital technology upscaling. Malawi, Mozambique, and Tanzania have enabling environments that beg for improvement to facilitate large scale adoption and upscaling of digital technology. Other key constraints that undermine the adoption and use of digital technologies across the Zambezi River Basin countries are related to availability, access, affordability, technology design, ease of doing business, cultural and family norms, gender, and poor user skills. The cost of data was observed to be one of the major constraints for digital technology use in climate change adaptation across several countries. Macroeconomic conditions, particularly inflation and lack of foreign exchange, also undermine growth prospects of digital technology adaptation as many of these technologies need to be imported. It is interesting that correlations between enabling environment indicators and digitalization variables appear to reveal a positive relationship signifying that to upscale the use of digital technologies in agriculture, it is critical to address parameters within the enabling environments including, pre-requisite infrastructure, macro-economic stability, policy, and regulatory environment.
Digital innovation in citizen science to enhance water quality monitoring in developing countries
(Working Paper, 2023-12-31) Pattinson, N. B.; Taylor, J.; Dickens, Chris W. S.; Graham, P. M.
Freshwater systems are disproportionately adversely affected by the ongoing, global environmental crisis. The effective and efficient water resource conservation and management necessary to mitigate the crisis requires monitoring data, especially on water quality. This is recognized by Sustainable Development Goal (SDG) 6, particularly indicator 6.3.2., which requires all UN member states to measure and report the ‘proportion of water bodies with good ambient water quality’. However, gathering sufficient data on water quality is reliant on data collection at spatial and temporal scales that are generally outside the capacity of institutions using conventional methods. Digital technologies, such as wireless sensor networks and remote sensing, have come to the fore as promising avenues to increase the scope of data collection and reporting. Citizen science (which goes by many names, e.g., participatory science or community-based monitoring) has also been earmarked as a powerful mechanism to improve monitoring. However, both avenues have drawbacks and limitations. The synergy between the strengths of modern technologies and citizen science presents an opportunity to use the best features of each to mitigate the shortcomings of the other. This paper briefly synthesizes recent research illustrating how smartphones, sometimes in conjunction with other sensors, present a nexus point method for citizen scientists to engage with and use sophisticated modern technology for water quality monitoring. This paper also presents a brief, non-exhaustive research synthesis of some examples of current technological upgrades or innovations regarding smartphones in citizen science water quality monitoring in developing countries and how these can assist in objective, comprehensive, and improved data collection, management and reporting. While digital innovations are being rapidly developed worldwide, there remains a paucity of scientific and socioeconomic validation of their suitability and usefulness within citizen science. This perhaps contributes to the fact that the uptake and upscaling of smartphone-assisted citizen science continues to underperform compared to its potential within water resource management and SDG reporting. Ultimately, we recommend that more rigorous scientific research efforts be dedicated to exploring the suitability of digital innovations in citizen science in the context of developing countries and SDG reporting.
The economywide impacts of increasing water security through policies on agricultural production: The case of rice and sugarcane in Pakistan
(Working Paper, 2023-12-31) Davies, Stephen; Akram, Iqra; Ali, Muhammad Tahir; Hafeez, Mohsin; Ringler, Claudia
Increasing demand for water juxtaposed with shrinking supplies will require a transfer of water resources out of agriculture into the domestic, industrial, and ideally environmental sectors. To examine the potential of policies to facilitate a release of water from agriculture, this paper uses IFPRI’s Computable General Equilibrium Model with a water extension, CGE-W, to assess the impact of commodity taxes on two highly water consumptive crops, rice and sugarcane, on water consumption and the overall economy. We find that land use grows by 1.56 million acres overall when the tax is imposed on both commodities, while 3.2-million-acre feet (MAF) of consumed water, equivalent to 6.35 MAF of water withdrawals, are released from agriculture. These outcomes are due to sugarcane’s reduced use of land over two cropping seasons and significant changes in cropping patterns. The study also examined releases of water from other possible policy measures and found that an even tax rate of 30% on sugarcane, rice and cotton yields 8.73 MAF of water from agriculture. However, with a hotter, drier climate virtually all these releases of water disappear because water must stay in agriculture due to higher evaporation and less precipitation, which raises irrigation demands. The needed policies will go beyond just taxation and might include changing cropping patterns and irrigation practices, as well as development of drought resistant varieties. Other approaches, such as buying tubewells from farmers, and developing markets for nonagricultural purchases of water, may have a role. The role of international trade in sugar and rice is shown to be significant and should be considered further in these analyses.
Inclusion in agri-food systems in Bangladesh: the digital innovation and transformation initiative
(Working Paper, 2023-09-20) Sarker, F.; Mamun, K. A.; Uddin, J.; Ahmed, S.; Nisha, N. A.; Joshi, Deepa
Agriculture has played a crucial role in supporting smallholder livelihoods in Bangladesh. Despite being actively involved in various stages of production, including seed sowing, harvesting, and postharvesting, women's contributions are often undervalued. They are often regarded as a cheap labor force and are not given meaningful roles in the supply and value chains. One of the primary challenges they face is the lack of access to and ownership of land, which results in limited and unequal access to resources such as credit, services, markets, and information on modern technologies. These disparities hinder women's participation in market systems and further widen gender gaps and digital divides. Studies have shown that Bangladesh has one of the highest gender gaps in mobile internet usage among low and middle-income countries. This study examines the gender digital divide in Bangladesh, focusing on the reasons behind women's exclusion from digital information highways and their limited access to, use of, and benefits from internet-based agriculture and climate-related services and innovations. In addition to a comprehensive review of secondary data, we conducted a needs-based assessment using both quantitative and qualitative indicators in three divisions. Qualitative data were collected through focus group discussions, in-depth interviews, and key informant interviews. Both the qualitative and quantitative studies shed light on the social, economic, and contextual issues related to the digital ecosystem in the agriculture sector. The assessment also evaluates the effectiveness of public, private, and civil society interventions in the study areas. Our findings reveal that most digital initiatives fail to address the economic gaps and challenges faced by smallholder farmers, poor women, and rural youth. To address these challenges and promote gender equality in agriculture, it is crucial for the government to implement consistent policies across government agencies and develop strategies that prioritize closing digital divides in the agricultural sector.
Options for digital twin application in developing country river basin management: a review
(Working Paper, 2023-11-21) Botai, Joel O.; Ghosh, Surajit; Matheswaran, Karthikeyan; Dickens, Chris; Langa, Nkateko; Garcia Andarcia, Mariangel
A Digital Twin (DT) is a digital representation of reality. This report explores the implementation of DT in the context of basin scale water management, with a particular focus on developing countries. The review begins with an examination of the background of DT and then delves into successful applications of DT particularly in developing nations. It also explores the potential of integrating Virtual Reality (VR) technologies as a part of DT, emphasizing the importance of stakeholder needs assessment for effective deployment. The review highlights the significance of data infrastructure architecture and data governance in the context of Digital Twins. The review concentrates on the published literature and the application of Digital Twins to river basins, emphasizing their role in decision-making at this level and outlining various use cases for water management. Furthermore, it assesses the expected impact of DT through the lens of the Sustainable Development Goals (SDGs). The review concludes by exploring the integration of Artificial Intelligence (AI) in the context of DT for river basins. Overall, this review summarizes the potential benefits and challenges of implementing DT for water management in developing countries.
Environmental flows in support of sustainable intensification of agriculture in the Letaba River Basin, South Africa
(Working Paper, 2023-08-08) Dickens, Chris; Whitney, Cory W.; Luedeling, Eike; Dlamini, V.; O’Brien, G.; Greffiths, Ikhothatseng Jacob
This study evaluates the socioecological consequences of the potential trade-offs between maintaining environmental flows (e-flows) and providing water for sustainable subsistence agriculture and livelihoods to the vulnerable human communities living along the lower Great Letaba River in South Africa. Implementation of e-flows is now generally recognized as an essential part of water resources management as they are designed to ensure that sufficient water is retained in a river to protect river ecosystems and all the beneficiaries of services that arise from those ecosystems. Understanding the relationship between e-flows and the use of water for small-scale agriculture is important for the management of trade-offs. The Letaba River Basin and it's tributary, the Great/Groot Letaba, are located in the eastern part of the Limpopo province in South Africa. This is one of the most important river basins in the region supporting both large-scale commercial and small-scale farmers. The river sustains many vulnerable human communities who depend on the ecosystem services provided by the river. Yet, the water resources of the Letaba River are heavily overutilized due to expanding developments, including upstream dams with associated offtakes mostly for irrigation. The findings of the study indicate that irrigation water demand from subsistence agriculture in the Great Letaba Basin amounted to around 2 million cubic meters annually with median demand not exceeding 300,000 cubic meters per month. This means that irrigation water demand from smallholder agriculture only amounts to about one-tenth of the estimated e-flow requirement. However, small-scale farmers contend with an increasing crop water gap which limits irrigated agriculture, especially during the dry season. Given the need to sustainably maintain e-flows for ecological purposes, crop water gaps are only likely to increase and compromise the sustainability of irrigated agriculture. With active upstream supplementation of river flows from dams to maintain both environmental and livelihoods-oriented river flows, the crop water gap can be fully eliminated. This supplementation is not assured due to competing uses.
The link between small reservoir infrastructure and farmer-led irrigation: case study of Ogun Watershed in southwestern Nigeria
(Working Paper, 2023-03-02) Oke, Adebayo Olubukola; Cofie, Olufunke O.; Merrey, Douglas J.
Small water infrastructure in Nigeria needs to be utilized more efficiently. There are over 900 small reservoirs across the country. Many of these have yet to be put to productive use within the Ogun watershed in the Ogun Osun River Basin. This study investigates the challenges and opportunities for improving the use of small reservoirs for farmer-led irrigation in a sustainable way. The 20 small reservoirs investigated showed varying degrees of degradation of the hydraulic structures, poor embankment maintenance evidenced by the observed erosion, overgrown shrubs, spillway cracks and failures, and siltation of the reservoir. Poor water management and irrigation practices due to weak technical capacity are also observed. There needs to be a precise governance arrangement or policy supporting water use in such a situation. The economic interests and considerations of the farmers determine the irrigation activities around the reservoirs. Regulations and management of the reservoirs were based on what was considered appropriate by the farmers. With the increasing interest in the use of small reservoirs as water sources for farmer-led irrigation in Nigeria, increased capacity building and training, access to agricultural inputs, finance, and the transformation of commodity associations to water users’ associations would contribute to improving the productivity of small reservoirs.
Data quality deterioration in the Lake Tana Sub-basin, Ethiopia: scoping study to provide streamflow and water withdrawal data
(Working Paper, 2022) Taye, Meron Teferi; Haile, Alemseged Tamiru; Genet, A.; Geremew, Y.; Wassie, S.; Abebe, B.; Alemayehu, B.
This working paper was prepared under a research project from the Future Leaders – African Independent Research (FLAIR) fellowship programme – focusing on understanding hydrological changes in the Lake Tana sub-basin, Ethiopia, due to water abstraction, land use and climate change. FLAIR is funded by the UK government’s Global Challenges Research Fund (GCRF) through The Royal Society, UK. The study was jointly conducted by the International Water Management Institute (IWMI) and staff of the Abbay Basin Development Office (ABDO). The paper provides information on the deterioration of streamflow data quality in the sub-basin. It demonstrates how to support the sub-basin by generating primary data and compiling current water abstraction data that are relevant for development planning. The project showed the possibility of conducting such activities with limited financial resources and time constraints but with strong collaboration. This work also demonstrated the need for a data alliance among stakeholders in the sub-basin.
Change in global freshwater storage
(Working Paper, 2022) McCartney, Matthew P.; Rex, William; Yu, Winston; Uhlenbrook, Stefan; Gnechten, Rachel von
Freshwater in both natural and man-made stores is critical for socioeconomic development. Globally, cumulative reduction in terrestrial water storage from 1971 to 2020 is estimated to be of the order of 27,079 Bm3. Although insignificant in comparison to the total volume stored, the decrease in ‘operational’ water stored (i.e., the proportion of water storage that is sustainably utilizable by people) is estimated to be of the order of 3% to 5% since 1971. In many places, both natural and man-made water storage are declining simultaneously, exacerbating water stress. Conjunctive use of different water stores is a prerequisite for water security and it is vital that natural water stores are fully integrated, alongside man-made water infrastructure, in future water resources planning and management.
