Accelerating change to solve the water and sanitation crisis
This year’s theme for World Water Day 2023 is “accelerating change to solve the water and sanitation crisis.” At IWMI, we are proud to be an organization that researches innovative solutions and scales them to improve water security in more than thirty countries across the Global South. Through our partnerships and innovations, IWMI researchers are providing solutions that transform not only water security, but also consider how water intersects with climate resilience, food security, and sustainable ecosystem management, all while promoting gender equity, youth inclusion and advocating for the populations most vulnerable to these crises.
Accelerating change to solve water crises means recognizing that every drop of water counts—and so does the work of our young researchers who are tackling water and sanitation challenges. That’s why this #WorldWaterDay we are highlighting the contributions of our research interns and consultants to projects ranging from food rescue in Sri Lanka to analyzing gaps in urban water policies in Pakistan.
We encourage you to follow IWMI’s social media pages to watch short videos on projects underway in Africa, the Middle East, and Southern and Southeast Asia.

We advance a gender equality and social inclusion (GESI) framework for incorporating climate information services (CIS), which is now becoming central due to the ongoing climate change and climate variability. We understand gender as a social construct of who women and men are supposed to be. Gender inequalities seem to be enduring such that, despite innovations in agricultural and climate information technologies, unequal gender power dynamics will still emerge. As far back as the 1960s, the gendered inequalities in accessing technologies could be identified. Such a historical analysis clearly shows that the different technological solutions are clearly embedded within the society in which they evolve in. The paper uses a literature review methodological approach whilst informing the implementation of an ongoing Accelerating Impacts of CGIAR Climate Research for Africa (AICCRA) Project. The findings reveal that unless women are intentionally included in designing and developing agricultural technologies, specifically climate information systems, there is a danger that women will be excluded from the benefits. Conway’s law clearly stipulates that technological innovations are not neutral as they are a projection of the values of their creators. It is, therefore, central to grasp the values of creators of different technological solutions and innovations. The key findings are built around the espoused conceptual framework, which has five indicators, namely: (1) gender targeting by intentional design, (2) collection of sex-disaggregated data, (3) conduct an analysis of the sex-disaggregated data, (4) dissemination of the technological options and (5) conduct continuous monitoring of gender and ongoing empowerment evaluation. The five indicator domains are further complemented by their respective assumptions. Our GESI recommendations are on the five selected indicator domains. These domains must be used within the three focal development areas: agricultural data hub, climate information services training, and flood and drought indicators, which are all being implemented in Zambia. Other AICCRA Project countries are Ethiopia, Ghana, Kenya, Mali, and Senegal. This paper engages why CIS has not gained significant traction in Africa, as it has not genuinely incorporated the differential gender technological nuances.

Domfeh, M. K.; Diawuo, F. A.; Akpoti, Komlavi; Antwi, E. O.; Kabo-bah, A. T. 2023. Lessons for pumped hydro energy storage systems uptake. In Kabo-Bah, A. T.; Diawuo, F. A.; Antwi, E. O. (Eds.). Pumped hydro energy storage for hybrid systems. London, UK: Academic Press. pp.137-154. [DOI] More...
Pumped hydro energy storage (PHES) has for years been touted as a suitable alternative for balancing the mismatch between demand and supply of electricity. As the world transits from a fossil fuel-based electricity sector to a renewable energy-based one, PHES is also continuously being used to resolve challenges regarding variable or intermittent sources of energy. This chapter presents lessons from countless literature and studies on the global development and market environment of PHES. The study reveals that critical factors such as investing in public-private research, development and deployment, instituting regulatory frameworks that stimulate innovative operation of PHES, increasing digital operation of PHES systems, and retrofitting PHES facilities could foster the uptake and revolutionize the development of PHES.

An accurate estimate of crop coefficient (Kc) values at different development stages (Kcini, Kcmid, and Kcend) is crucial for assessing crop water requirements in semi-arid regions. The objectives of this study were first to quantify the reference evapotranspiration (ETo) and to calculate the actual evapotranspiration (ETa) over citrus in a semi-arid climate under drip irrigation. For this purpose, a site of a citrus orchard in Souss-Massa, planted with the Esbal variety of clementine, was equipped with an Eddy-Covariance (EC) system, and sensors to measure radiation, soil heat flux, and micrometeorological forcing data, during 2020 and 2021 seasons. Also, the soil moisture content at various soil depths in the root zone near the EC tower was monitored. The energy balance closure (EBC) approach was adopted for flux assessment to ensure a quality check for the EC measurements. The obtained EBCs were about 82% and 79% for the daily measurements in 2020 and 2021, respectively, which can be considered acceptable considering the nature of the citrus orchard (relatively tall and sparse). Second, the study aimed to estimate actual Kc act values for citrus under the same irrigation strategy. The derived values were compared to different recommended Kc values in the literature. In the third stage, this work aimed to offer an alternative plan to sustainable irrigation management by elaborating an irrigation schedule for citrus crops in the region using the FAO-56 simple approach to avoid water stress and deep percolation (i.e., Ks = 1 and DP = 0). Eventually, an irrigation schedule was drawn following the crop’s phenological stages. The seasonal mean citrus evapotranspiration (ETa) values are 1.68, 3.02, and 1.86 mm/day for the initial, mid, and end-season. The seasonal actual Kc act values were 0.64, 0.58, and 0.64 for Kcini, Kcmid, and Kcend, respectively. Additionally, the application of the water balance equation revealed that a large quantity of water is lost through deep percolation (52% of total water supplied). The study focuses on Citrus trees being a strategic crop with important socio-economic values in the Souss-Massa region. Thus, the results should support both scientists and farmers in planning and strategy development.

This paper assessed existing EWS challenges and opportunities in cloud computing through the PSALSAR framework for systematic literature review and meta-analysis. The research used extant literature from Scopus and Web of Science, where a total of 2516 pieces of literature were extracted between 2004 and 2022, and through inclusion and exclusion criteria, the total was reduced to 98 for this systematic review. This review highlights the challenges and opportunities in transferring in-house early warning systems (that is, non-cloud) to the cloud computing infrastructure. The different techniques or approaches used in different kinds of EWSs to facilitate climate-related data processing and analytics were also highlighted. The findings indicate that very few EWSs (for example, flood, drought, etc.) utilize the cloud computing infrastructure. Many EWSs are not leveraging the capability of cloud computing but instead using online application systems that are not cloud-based. Secondly, a few EWSs have harnessed the computational techniques and tools available on a single platform for data processing. Thirdly, EWSs combine more than one fundamental tenet of the EWS framework to provide a holistic warning system. The findings suggest that reaching a global usage of climate-related EWS may be challenged if EWSs are not redesigned to fit the cloud computing service infrastructure.

Freshwater biodiversity loss is accelerating globally, but humanity can change this trajectory through actions that enable recovery. To be successful, these actions require coordination and planning at a global scale. The Emergency Recovery Plan for global freshwater biodiversity aims to reduce the risk for freshwater biodiversity loss through six priority actions: (1) accelerate implementation of environmental flows; (2) improve water quality to sustain aquatic life; (3) protect and restore critical habitats; (4) manage exploitation of freshwater species and riverine aggregates; (5) prevent and control nonnative species invasions in freshwater habitats; and (6) safeguard and restore freshwater connectivity. These actions can be implemented using future-proofing approaches that anticipate future risks (e.g., emerging pollutants, new invaders, and synergistic effects) and minimize likely stressors to make conservation of freshwater biodiversity more resilient to climate change and other global environmental challenges. While uncertainty with respect to past observations is not a new concern for freshwater biodiversity, future-proofing has the distinction of accounting for the uncertainty of future conditions that have no historical baseline. The level of uncertainty with respect to future conditions is unprecedented. Future-proofing of the Emergency Recovery Plan for freshwater biodiversity will require anticipating future changes and developing and implementing actions to address those future changes. Here, we showcase future-proofing approaches likely to be successful using local case studies and examples. Ensuring that response options within the Emergency Recovery Plan are future-proofed will provide decision makers with science-informed choices, even in the face of uncertain and potentially new future conditions. We are at an inflection point for global freshwater biodiversity loss; learning from defeats and successes can support improved actions toward a sustainable future.

Enabling gender and youth inclusion
Agriculture is the bedrock of food and nutrition security and a major source of income and employment in many developing countries. Inclusive agriculture, provides opportunities for women and youth who have historically been excluded from agriculture-led economic growth. Enhancing gender and youth inclusion in high-value agricultural value chains has the potential to increase the production of nutrient-rich, profitable crops and create attractive job opportunities for currently disadvantaged groups. Inclusive agriculture includes ensuring that women, youth and other vulnerable groups gain equitable access to water resources and technologies to support agronomic growth.
IWMI conducts comprehensive analyses of the policy framework and interventions in value chains in key geographies to clarify the barriers to gender and youth inclusion. Inclusion segmentation is also carried out to understand the investment needs and abilities of women and youth regarding innovation. IWMI then makes recommendations and develops evidence-based strategies to enable public and private sector actors to achieve sustainable and inclusive scaling of water solutions and agricultural innovation bundles. Among these strategies are internships with private sector companies for young professionals and entrepreneurs. These create win-win situations in which companies benefit from interns’ specific knowledge or skills while interns gain valuable private sector work experience and mentorship.

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.

Co-developing innovation bundles
Although agricultural water is still mainly funded by the public sector, private sector organizations and farmers are increasingly investing in innovative water management and irrigation technologies. At the same time, simply increasing the amount of finance flowing to the agricultural water sector is not enough to guarantee the uptake of innovative solutions. Investments must also be responsible, targeted and bundled with improved inputs and services, market information and access, and digital payment methods.
Consequently, IWMI partners with farmers and public and private sector actors to co-develop contextually relevant socio-technical-institutional-financial and process innovation bundles that are contextually relevant. IWMI integrates the scaling of innovation bundles into agricultural and food value chains, for instance by strengthening market linkages, to enhance the impacts on farmers’ investments, incomes and livelihoods.

Strengthening and sustaining the enabling environment
Making agricultural innovations and water solutions available to farmers on a massive scale is crucial if the world is to meet growing food demands and mitigate climate change impacts. However, innovation scaling efforts often do not have the desired impact because they do not sufficiently consider the factors enabling and inhibiting farmers’ adoption of these innovations. In some instances, they may even produce undesirable impacts, including environmental degradation, loss of access to resources and social inequality. IWMI develops tools and other evidence-based resources to help partners and stakeholders understand and sustain the enabling environment and introduce measures to ensure scaling success. In addition, IWMI co-designs innovative, inclusive financial modalities to accelerate investment in innovations by farmers and agri-businesses.
A key part of this focus area is the Accelerator Program, for which 12 small and medium-sized agribusinesses were selected to scale five innovation bundles that support climate information services and climate-smart agriculture.

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.

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.

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.
This focus area contributes to the following One CGIAR impact areas:
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.

Enhancing capacity for system transformation
Food, land and water systems are complex networks of actors, institutions and activities related to the production, value addition and consumption of food. These systems are connected to and influenced by the structures and supporting mechanisms that underlie them. System transformation cannot occur without changing these underlying structures and supporting mechanisms. However, the capacity for actors to take up specific roles and responsibilities in scaling processes is sometimes lacking. Stimulating system transformation therefore requires enhancing actors’ capacity to assume their roles and responsibilities in the system to ensure that scaling processes provide equitable opportunities and contribute to sustainable development.
As a research institution, IWMI stimulates system transformation by building capacity within institutions and facilitating dialogue and collaboration between various stakeholders across sectors and their respective networks. IWMI does this by developing evidence-based capacity-strengthening programs and strategies. These include demand-driven internships with private sector entities and innovation hackathons.
This focus area contributes to the following One CGIAR impact areas:
Fostering scaling partnerships
Private sector actors play a central role in the dissemination and adoption of technologies and services such as information, financing, and pre- and after-sales support. IWMI has established scaling partnerships with private sector companies across Africa and Asia. Besides technical assistance, IWMI provides its partner companies with research evidence and advice, risk and suitability assessments and capacity strengthening for effective climate change-related planning and management.
Armed with these tools and resources, companies are better equipped to identify and reach their target customers in ways that are equitable, economically viable and environmentally sustainable. At the same time, farmers benefit from better access to innovations vital for improving livelihoods and climate adaptation.

Cultivating scaling preparedness
Scaling preparedness is a set of actions undertaken throughout the scaling process to maximize the adoption of innovation bundles, accelerate scaling and increase the likelihood of achieving transformational change. In cultivating scaling preparedness, stakeholder engagement is key to gain stakeholders’ buy-in, commitment, resource contribution and investment as well as adaptability. By cultivating scaling preparedness, IWMI is better able to identify and develop high-potential innovation bundles with the greatest chance of being successfully scaled.

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.
This focus area contributes to the following One CGIAR impact areas:
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.
This focus area contributes to the following One CGIAR impact areas:
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.
This focus area contributes to the following One CGIAR impact areas:
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.
This focus area contributes to the following One CGIAR impact areas:
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.
This focus area contributes to the following One CGIAR impact areas:
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.
