This year, the first-ever Middle East and North Africa Climate Week will be held in Dubai from March 28-31. A key conference on the road to the COP27 climate summit in Sharm el-Sheikh, Egypt, MENA Climate Week will bring together government policymakers, private sector representatives, members of civil society, and other key stakeholders to discuss current and future climate challenges across the MENA region and shine a spotlight on potential climate solutions.
Through event participation, media availability, and donor and partner meetings at MENA Climate Week, IWMI will establish key linkages between water, climate, and sustainable development in the MENA region while using the conference as a springboard to secure prominent placement for water security, food security, and climate resilience on the COP27 agenda. MENA Climate Week also offers IWMI and our partners a powerful platform to highlight our ongoing work across the region to strengthen water and climate security and promote innovative, scalable water solutions that can help lay the foundation for a climate-resilient future for the region.
A key stop on the road to COP27, the conference allowed IWMI to share blueprints for creating more water-secure, climate-resilient communities across the Middle East and North Africa.
With the first-ever Middle East and North Africa Climate Week just concluded, learn how improved drought preparedness is helping strengthen the region’s resilience to climate change.
While MENA Climate Week may last only four days, adaptation actions need to accelerate fast to continue the region’s development, and the success of both comes down to smarter water management.
Small reservoirs are one of the most important sources of water for irrigation, domestic and livestock uses in the Upper East Region (UER) of Ghana. Despite various studies on small reservoirs in the region, information on their spatial-temporal variations is minimal. Therefore, this study performed a binary Random Forest classification on Sentinel-2 images for five consecutive dry seasons between 2015 and 2020. The small reservoirs were then categorized according to landscape positions (upstream, midstream, and downstream) using a flow accumulation process. The classification produced an average overall accuracy of 98% and a root mean square error of 0.087 ha. It also indicated that there are currently 384 small reservoirs in the UER (of surface area between 0.09 and 37 ha), with 20% of them newly constructed between the 2016-17 and 2019-20 seasons. The study revealed that upstream reservoirs have smaller sizes and are likely to dry out during the dry season while downstream reservoirs have larger sizes and retain substantial amounts of water even at the end of the dry season. The results further indicated that about 78% of small reservoirs will maintain an average of 54% of their water surface area by the end of the dry season. This indicates significant water availability which can be effectively utilized to expand dry season irrigation. Overall, we demonstrate that landscape positions have significant impact on the spatial-temporal variations of small reservoirs in the UER. The study also showed the effectiveness of remote sensing and machine learning algorithms as tools for monitoring small reservoirs.

Globally, the energy sector accounts for almost three-quarters of total greenhouse gas (GHG) emissions and is thus responsible for the majority of adverse climate change impacts on rural livelihoods, including growing water, energy, and food insecurity and environmental degradation. According to a recent report from the Intergovernmental Panel on Climate Change, annual investments of US$2.4 trillion (2010 dollars) in energy systems are needed to limit global warming to 1.5C. Such investments would support decarbonizing the largest polluters and improving energy efficiency. More and cheaper clean energy technologies and greater energy efficiency are equally critical for accelerating access to energy in underserved rural areas in ways that promote ecosystem health and inclusivity.

The United Nations Food Systems Summit aimed to chart a path toward transforming food systems toward achieving the Sustainable Development Goals. Despite the essentiality of water for food systems, however, the Summit has not sufficiently considered the role of water for food systems transformation. This focus is even more important due to rapidly worsening climate change and its pervasive impacts on food systems that are mediated through water. To avoid that water “breaks” food systems, key food systems actors should 1) Strengthen efforts to retain water-dependent ecosystems, their functions and services; 2) Improve agricultural water management; 3) Reduce water and food losses beyond the farmgate; 4) Coordinate water with nutrition and health interventions; 5) Increase the environmental sustainability of food systems; 6) Explicitly address social inequities; and 7) Improve data quality and monitoring for water-food system linkages.

CONTEXT: Although rice production has increased significantly in the last decade in West Africa, the region is far from being rice self-sufficient. Inland valleys (IVs) with their relatively higher water content and soil fertility compared to the surrounding uplands are the main rice-growing agroecosystem. They are being promoted by governments and development agencies as future food baskets of the region. However, West Africa’s crop production is estimated to be negatively affected by climate change due to the strong dependence of its agriculture on rainfall.
OBJECTIVE: The main objective of the study is to apply a set of machine learning models to quantify the extent of climate change impact on land suitability for rice using the presence of rice-only data in IVs along with bioclimatic indicators.
METHODS: We used a spatially explicit modeling approach based on correlative Ecological Niche Modeling. We deployed 4 algorithms (Boosted Regression Trees, Generalized Linear Model, Maximum Entropy, and Random Forest) for 4-time periods (the 2030s, 2050s, 2070s, and 2080s) of the 4 Representative Concentration Pathways (RCP2.6, RCP4.5, RCP6.0, and RCP8) from an ensemble set of 32 spatially downscaled and bias-corrected Global Circulation Models climate data.
RESULTS AND CONCLUSIONS: The overall trend showed a decrease in suitable areas compared to the baseline as a function of changes in temperature and precipitation by the order of 22–33% area loss under the lowest reduction scenarios and more than 50% in extreme cases. Isothermality or how large the day to night temperatures oscillate relative to the annual oscillations has a large impact on area losses while precipitation increase accounts for most of the areas with no change in suitability. Strong adaptation measures along with technological advancement and adoption will be needed to cope with the adverse effects of climate change on inland valley rice areas in the sub-region. SIGNIFICANCE: The demand for rice in West Africa is huge. For the rice self-sufficiency agenda of the region, “where” and “how much” land resources are available is key and requires long-term, informed planning. Farmers can only adapt when they switch to improved breeds, providing that they are suited for the new conditions. Our results stress the need for land use planning that considers potential climate change impacts to define the best areas and growing systems to produce rice under multiple future climate change uncertainties.

Gender, intersectionality and social inclusion
It is critical to center gender and intersectional identities when unpacking migration phenomena. Gender as a social construct guides social norms and relations, including the decision-making processes and mechanisms leading to migration. We recognize that the intersections between race, age, class, sex, caste and region shape the migrant experience.
IWMI strives to offer transformative approaches and solutions for women, youth and marginalized groups, regarding them as equal partners in our work rather than passive end-users. For example, within communities that experience male out migration, socio-political systems are restructured to make women, youth and other groups active agents in their own agri-food transformation. Migration patterns contribute to the feminization of agriculture, and women may experience a greater burden of responsibility coupled with an increased ability to access and control resources and policies to build sustainable livelihoods. Acknowledging social complexities helps researchers and communities understand migration trends and address structural power imbalances to build a more equitable world.

Water, climate change and agrarian stress
Migration, water and climate stress are inextricably linked to rural development. Water stress and climate variability can act as a driver of fragility, intensifying pre-existing political, social, economic and environmental challenges. Initiatives designed to address migration-related challenges must tackle inequalities and the exclusion of women, youth and marginalized groups; governance opportunities to better manage water and natural resources and technology and innovations to help communities escape socio-ecological precarity and thrive despite climate challenges. IWMI intends to build climate resilience by implementing projects which tackle gender-power inequalities in the face of dynamic, economic-social-ecological challenges. Our work brings together affected communities, institutional stakeholders and social actors to manage water in response to climate variability and agrarian stress, striving to address complex physical and social variables.

Covid-19 disruption & adaptation
Covid-19 has caused a rupture in migration logistics and exposed inequities in the migration system, yet drivers of movement remain. Government lockdowns and closed borders due to the pandemic curtailed movement for migrants, posing complex problems for migrant hosting and origin countries. There have been significant economic shocks, with a sharp decline in unemployment for migrants and an inability to send money home through remittances to support family. Some migrants face social stigma for returning home without an income, particularly if families relied on loans to support their journeys. Consequences have been severe for informal migrants who lack government protection in their host countries. Migrants, particularly those living in crowded, lower-income neighborhoods, have been experiencing stigmatization related to the spread of Covid-19. We look at the impacts of Covid-19 on migration governance and rural areas across seven countries,development planning in Ghana, migration challenges in Southeast Asia, and community-based disaster management and resilience building in South Africa.

Urban & rural transformation
As agricultural opportunities fluctuate in rural areas, migration, particularly to urban areas, is an adaptation technique to secure incomes and alternative livelihoods. Income generated by migrants is often sent back to family as remittances to support communities at home. At IWMI, we assess linkages between rural and urban areas, as well as the role of agricultural knowledge systems and food and water security. We recognize there are complex push and pull factors such as individual aspirations, economic opportunity, social norms, climate variability and government policies which drive migration and affect rural communities, particularly youth. Our work follows a ‘positive migration’ philosophy, framing migration as an adaptation technique and socio-economic choice (in many cases) rather than a problem to be solved, and focuses on establishing safer, more regular migration by supporting changes to migration governance in sending regions.

Economics and equity
At IWMI, researching underlying economic and social trends helps us understand why people migrate. They also explain the impact of remittances and loss of agricultural labor, as well as consequences of migration on gender roles and food and water security. For instance, communities with higher levels of income inequality, or relative deprivation, may experience greater levels of out-migration compared to consistently low-income communities. In addition, migration changes intra-household gender-labor composition, which can change the access of smallholders to water resources, affecting the functioning of community-based institutions and consequently household and local food security. IWMI also focuses on circular economy, a strategy to recover and reuse waste, to boost food security and understand how interventions can encourage refugee and host communities to retain scarce resources.

Human capacity development and knowledge exchange
Scaling farmer-led irrigation requires strengthening human capacity and knowledge exchange among all actors and stakeholders involved. IWMI takes an action research approach, working with national and international research institutions, governments, extension agents and public and private organizations to co-develop the scaling ecosystem and strengthen capacity to drive scaling networks and collective action. We support the development of or reinforce national multi-stakeholder dialogues with the aim of sharing scaling experiences and realizing win-win collaboration, interactive learning and capacity development. Other modalities for capacity development include hackathons, innovation research grants for bachelor’s and master’s students, private sector scaling grants and innovation internships with private companies. These all serve to stimulate local and contextually relevant innovation, close the research-private sector divide and enhance job readiness among young professionals.

Financing ecosystem
A lack of affordable credit, particularly for women and resource-poor farmers, is one of the main barriers to expanding farmer-led irrigation in low- and middle-income countries. But credit alone is not enough. Financing for irrigation equipment must be embedded in a wider financing ecosystem that bundles credit with inputs and services, market information and access, and technology such as digital payment. In several countries, irrigation equipment suppliers are stepping in to provide financing directly to farmers. In doing so, they increase their own risk. To address this issue, IWMI works with farmers, private companies, finance institutions and development partners such as the World Bank Group to analyze whether credit-scoring tools are inclusive. We also help to identify gaps in the financing ecosystem and de-risk the private sector from testing innovative end-user financing mechanisms that take into account farming system typologies, financial and social capital and crop seasonality.

Adaptive scaling and partnerships
The ability of farmers to engage in or expand irrigation depends on the prevailing socioeconomic, ecological and political contexts, which are often complex, non-linear and changeable. Overcoming systemic barriers to farmer-led irrigation development while taking advantage of existing opportunities requires scaling processes to be adaptive. This means diverse actors feed off, adapt to, support, cooperate, compete and interact with each other, forming different multi-actor networks and engaging in collective action to undertake various functions in the scaling ecosystem. IWMI works with farmers and public and private sector partners to co-design and pilot contextually relevant innovation bundles and their scaling pathways or strategies, influence policies and accelerate the transition to scale of innovations with demonstrated early impact.

Environmental sustainability
Population pressure and increasing water competition in a changing climate require us to take stock of the availability and use of water across scales. Water availability not only influences farmers’ commercial prospects but also irrigation-related enterprises and agri-businesses. Greater water scarcity could jeopardize irrigation and agricultural markets while excessive water use can lead to declining ecosystems, water quality and soil health. IWMI advises development partners and the public and private sectors on all aspects of water resource availability and use through a variety of advanced modeling and remote-sensing products and tools, including Water Accounting+, solar irrigation mapping and internet of things. These are complemented by multi-criteria analysis to evaluate the potential of irrigation expansion, taking into consideration environmental flows. With our private sector partners, we are leveraging converging technologies, such as sensors on solar pumps that capture usage data, to encourage better resource management and governance.

Gender and social inclusion
The barriers facing women and men in accessing irrigation technologies are not the same. Neither are the benefits. Social, cultural and religious norms influence inter- and intra-household power relations. These, in turn, affect access to resources such as land, credit, information and training. IWMI carries out cross-dimensional analysis of gender and social inclusion in policy, financing, livelihood assets and access, institutional approaches and interventions as well as gender-based technology preferences. For example, we work with farmers, financial institutions and the private sector to address gender-based constraints in credit scoring and enhance women’s purchasing power. But benefitting from farmer-led irrigation does not stop at accessing and adopting technologies; enabling women and resource-poor farmers to participate in input and output markets is equally important to ensure that investments in irrigation result in improved nutrition and economic empowerment. Other ways we enhance gender and social inclusion include tackling agency issues around financial management and literacy, livelihood diversity and social capital as well as access to infrastructure, extension services and market linkages.

Innovation bundles
Farmer-led irrigation development is about much more than installing a pump in a field. It requires access to financing, labor, energy, and input and output markets, so that investments in irrigation translate into sustainable returns. IWMI uses a systemic approach to understand the farming system as well as the factors in the enabling environment that prevent women, men and youth from engaging in and benefitting equitably from farmer-led irrigation. We partner with farmers and the public and private sectors to test contextually relevant innovation bundles that combine irrigation technology such as solar pumps with financing mechanisms like pay-as-you-own or pay-as-you-go, agricultural inputs and agronomic techniques. We also look at ways to improve on-farm water management and nutrient use efficiency and reduce evapotranspiration through digital advances and agricultural extension. We integrate the scaling of innovation bundles into agricultural value chains to enhance the impacts on farmers’ irrigation investments, incomes and livelihoods.
