Volta River Basin Research Highlights

 

The implementation of integrated rainwater management practices can lead to more equitable and multipurpose use of small reservoirs

 
 

 

OVERVIEW

Summary of Research in the Volta



The farmers in the Volta River basin, some of the poorest in the world, generally rely on rain-fed agriculture. However, insufficient or irregular rainfall frequently puts farmers at risk of losing their crops. In addition, climate change is making already variable rainfall less reliable.

Facilitating CollectiveThe risk of losing crops makes farmers reluctant to invest in agriculture and water management. Farmers must have access to a reliable water supply to sustain their livelihoods.

The Challenge Program on Water and Food (CPWF) began its research in the Volta river basin in 2003. Between 2003 and 2008, twelve independent projects conducted research on a wide range of water and food-related issues. When designing its second round of projects, CPWF decided to limit its focus to one theme and one geographical area. Thus, between 2010 and 2013, CPWF explored the institutional and technical aspects of rainwater management as well as small reservoir development and maintenance in Burkina Faso and northern Ghana. The research has been linked with similar CPWF research projects in the Nile and Limpopo river basins.

There are more than 1,700 small reservoirs scattered across Burkina Faso and northern Ghana. Initially, many reservoirs were built as watering holes for cattle, but they have come to serve multiple purposes, providing opportunities for farmers to mitigate the risks of variable rainfall.

Farmers use the reservoirs to help better manage the periods of drought and floods, trying to ensure that water is more consistently available for their crops and animals throughout the year.

Finding the OptimumHowever, external drivers of change such as population growth and climate change are putting pressure on the limited rainwater resources. Improved rainwater management is a necessity for smallholder farmers to intensify their production, i.e., use less water to grow more crops, rear more cattle, or both.

That’s why CPWF set out to find ways to strengthen integrated management of rainwater and small reservoirs, so they can be used equitably and for multiple purposes.

To achieve this objective, CPWF has used different research disciplines, partnered with local, national, and international organizations, and operated at the household, community, watershed, and basin levels.

Evolution of agricultural water management in rainfed crop-livestock systems of the Volta Basin (Working paper)



This study of the evolution of AWM in the Volta Basin yielded key recommendations for research-for-development interventions and new concepts for research on water management. When promoting agricultural water management strategies, projects should carefully study the available information on factors triggering adoption, and play on these to ensure sustainable uptake of the technology.

Structure and Agency: Understanding Policy Changes in West Africa (Journal article)



This paper argues that the ownership of policy reforms is the outcome of an interaction between individual agency and structural conditions. Taking the implementation of Integrated Water Resources Management (IWRM) in Burkina Faso (since 1996) and Mali (since 2004) as an entry point, the paper describes the interplay between national policy makers, international organizations and dominant development discourses in the shaping of water policy reforms in both countries over the past 15 years.

Linking Knowledge: A Qualitative Analysis of Gender and IWRM-related Policies in the Upper East Region of Ghana (Working paper)



This study includes a baseline on the activities and issue of women in the Upper East Region of northern Ghana. It also provides an analysis of the processes, opportunities and constraints of how and why women organize themselves in these particular social groupings. The paper concludes with an evaluation of how, if at all, IWRM-related district, regional and national level policies from government departments.

Facilitating Collective and Inclusive Decision Making on Integrated Water Resources Management in Burkina Faso (Outcome story)



In Burkina Faso, implementation of on-the-ground water governance lags behind the integrated water resources management policies the government has promoted for two decades. In order to address this gap, one CPWF project facilitated exchanges between a local water committee and its various stakeholders using companion modeling. The participatory discussion between local water committee members and farmers, pastoralists, fishermen, miners, women, civil society and policy makers resulted in a renewed effort by the committee to draft a management plan and assume its role in integrated water resources management implementation.

How Water and Agriculture Support Livelihoods in the Volta (Policy brief)



The Volta basin is inhabited by 19 million people, 70 per cent of whom are rural. However, by 2050, when the population is expected to be 50-60 million, the ratio of rural-to-urban populations will have decreased dramatically. Improvements in the rainfed systems coupled with investment in fertilizers and small-scale irrigation provide the main opportunity for development.

Finding the optimum balance between farming and the natural environment



How do you convince a farmer who is struggling to produce a crop not to plough additional land next to his local river, or how can you tell a fisherman who needs to provide for his family that he shouldn’t use certain pesticides to enhance his catch of fish? There are answers to each of these questions but often these answers involve more cost, time and labor to be borne by the local community. So why should they change their practices?

Demystifying the Volta’s Water Discourses



One component the Volta’s research focused on understanding how and why research and policies in the field of agricultural water management are framed in the Volta Basin. The main question they sought to answer is why certain policy and investment models (such as integrated water resources management [IWRM], soil and water conservation, irrigation development in small reservoirs) emerge and whose knowledge supports these investments.
