West Africa's rice imports currently satisfy 70% of the soaring local demand, worsening the food vulnerability of an increasingly urbanized population. Despite considerable rice-growing potential, lack of water control systems, access to improved seeds, agrochemicals and appropriate mechanization have resulted in modest production growth rates, unable to alter the region's dependency on imported rice. Governments aim to boost production with import duties and input subsidies. However, questions remain as to whether these policies enable the rice sector to respond to changing consumers preferences for high grade rice and to contribute to national economic growth. We present the results from a Policy Analysis Matrix (PAM) on rice production in Ghana, Burkina Faso and Niger and under three water management systems: irrigation (public scheme), supplemented rain-fed (rainfall aided by autonomously-sourced water supplies) and purely rain-fed. Our results show that policy interventions in these West African countries (i.e., input subsidies and import taxes) did not significantly enhance the profitability of rice production to farmers due to the effect of market failures (limited capital access and non-competitive market for rice) and the low quality of local milled rice. The PAM results point strongly to the importance of improving rice quality and yields through more efficient water management and post-harvest handling/processing and targeted breeding to match consumers' preferences.

Groundwater economic models have refined optimal extraction rules while lagging behind in the study of optimal spatial policies. This paper develops a theoretical model to estimate welfare gains from optimal groundwater management when the choice variable set is expanded to include well location decisions as well as optimal groundwater extraction paths. Our theoretical results show that if there is spatial heterogeneity in groundwater, the welfare gains from optimal location of wells are substantial even if extraction rates are unregulated. Furthermore, second-best economically defined spacing regulations may possibly have better efficiency results (and lower implementation costs) than first-best uniform taxes or quotas. An application of the model to a real-world aquifer shows the importance of including well location decisions in spatially differentiated groundwater models and the need for (1) robust estimates of the gains from optimal management and; (2) spatially explicit regulations.

The potential to increase agricultural production in inland valleys in West Africa has received a good degree of attention in both national development strategies and academic literature, and improving agriculture productivity in inland valleys has been an active area of donor engagement. Despite this attention, documentation of the degree to which benefits are enhanced through construction of built water storage infrastructure in such sites is somewhat scant. This paper examines evidence from eight inland valley sites with recently-built water retention infrastructure (4 in southwest Burkina Faso, 4 in southeast Mali) to determine how economic returns derived from agricultural production have changed through built infrastructure construction. Farmer interviews were undertaken at each site to identify costs and benefits of agricultural production before and after small built infrastructure construction. Overall results indicate that net present value increased substantially after built infrastructure was constructed. The results nonetheless highlight substantial variation in economic impacts across sites. A central variable explaining such variation appears to be the degree to which water retention is exploited for groundwater-based offseason cultivation. These findings will help development planners to better predict the degree and nature of change engendered by water storage projects in inland valley sites, and help to ground-truth grand statements about the development potential of this piece of natural infrastructure.
