Abstract

Water resources are essential to human development processes and to achieve the Millennium Development Goals that seek, inter alia, to eradicate extreme poverty and hunger, achieve universal literacy, and ensure environmental sustainability. Expanding irrigation is essential to increase agricultural production, which is needed to achieve economic development and attain food security in much of sub-Saharan Africa. Water resources and irrigated agriculture are not developed to their full potential. Currently less than 4% of renewable water resources in Africa are withdrawn for agriculture. Barriers include the lack of financial and human resources to build irrigation and related rural infrastructure and acquire agricultural technology, and inadequate access to markets. This constrains progress towards poverty reduction. We examine the linkages between agricultural water, education, markets and rural poverty through a review of published studies. We argue that, linking agricultural water, education, and market interventions, which are so often implemented separately, would generate more effective poverty reduction and hunger eradication programs. Investments in agricultural water management and complementary rural infrastructure and related policies are the pathways to break the poverty trap in smallholder African agriculture.

Water, a high profile issue in global poverty debate

Water resources are essential to human development processes and achieving the Millennium Development Goals (MDG), which seek: to eradicate extreme poverty and hunger (goal 1), with a target of halving the proportion of people living on less than $1 a day by 2015; to achieve universal primary education (goal 2); and to ensure environmental sustainability and stop unsustainable exploitation of water resources (goal 7). The Commission for Africa (2005) has called for doubling the spending on

Rural infrastructure and poverty

The causal linkages between agricultural output growth and poverty reduction are generally well accepted (Mellor, 1995, Thirtle et al., 2003). In turn, the linkages between infrastructure development and sustained output growth have been documented by many global empirical studies (Calderon and Chong, 2004, Canning and Bennathan, 2000) and worldwide reviews (Pinstrup-Andersen and Shimokawa, 2006). Cross-country analyses have also documented strong linkages between infrastructure and

Key pathways to breaking the poverty trap

Key pathways and investment options to reduce rural poverty in sub-Saharan Africa and Ethiopia are listed in Box 1. Positive synergies can be realized through integrated investments across sectors. However, successful approaches must be case-specific. Some studies from Ethiopia posit that the adoption of modern production technology and agricultural innovations is higher near micro-dams, due probably to irrigation. However, the incidence of water-borne diseases is greater near older sites,

Summary

We review the linkages between irrigation investments and poverty reduction with a focus on Africa. Investments in agricultural water, and other priorities, can contribute to poverty reduction through several pathways, including: higher productivity; higher employment; higher income and consumption; better nutrition and health; better education; lower variability in output, income, and employment; improved equity; multiple uses of water; and multiplier effects on non-farm sectors.
