Refereed/Peer-reviewed Meeting growing demand for water and food in Africa, and other parts of the Global South, presents a significant and critical challenge over the next 50 years. This paper draws on an ongoing project in Africa to outline the research-for-development work that is urgently required to facilitate a paradigm shift in agricultural water management. Such work should lead to increased productivity and profitability of agricultural water use to allow agriculture to release some water to meet the growing needs of other sectors, while still meeting food security needs and contributing to a prosperous rural population.

Contingent valuation is used to elicit irrigators’ willingness to pay for soil moisture tools in irrigation schemes in Africa, with various econometric methods employed to mitigate potential bias. Key results include that there is a neighbourhood effect influencing adoption, and that being located downstream and spending more on irrigation water positively and statistically significantly influenced willingness to pay for tools. The result suggests that although focusing on economic incentives and promoting farmer learning by those using the tools may promote greater adoption, there is likely to still be a need for co-investment by other bodies.

Agricultural production in sub-Saharan Africa has, in recent times, remained lower than the rest of the world. Many attribute this to factors inherent to Africa and its people, such as climate, soil quality, slavery and disease. This article traces the role of agriculture through history and argues that these are not the main reasons. Before the arrival of European traders, complex agricultural systems existed, which supported food security, manufacturing and trade. External interference manipulated these systems in pursuit of export crops. Independence has not fundamentally changed this; resource and wealth extraction continue to inhibit economic development for Africans in Africa. Refereed/Peer-reviewed

Irrigation development in Sub-Saharan Africa has lagged significantly behind that in other developing countries. Consequently, economic development and food security are also lagging behind. Since the mid-2000s there has been a resurgence in the willingness to invest in irrigation, and Sub-Saharan Africa has the largest potential of any developing region to benefit from it. However, to gain from new investment in irrigation without repeating past failures, it is critical to develop a business model for small-scale irrigation schemes. This article explores the barriers that such a model needs to address to be successful and the opportunities this represents for irrigators’ profitability. Refereed/Peer-reviewed

This study provides an overview of extension influence on the adoption of irrigation innovations in developed and developing countries, and finds that extension plays a more significant positive role in influencing soft technology adoption in developing countries. Case studies on the nature, use and availability of extension advice in six irrigation schemes in Tanzania, Mozambique and Zimbabwe are presented. The use of government extension officers varied significantly, with extension use not linked to farm outcomes. The results suggest the need to support more diverse sources of advice and to promote institutional reform in south-eastern Africa. Refereed/Peer-reviewed
