Financing of Irrigation essential for Africa south of the Sahara to achieve sustainable development

Atakos/CCAFS)The Third International Conference on Financing for Development is taking place in Addis Ababa this week with the goal of bringing together the global community to approve financial support for the Sustainable Development Goals (SDGs) and the Post-2015 Development Agenda. The draft outcome document, “Addis Ababa Action Agenda of the Third International Conference on Financing for Development,” rightly mentions that efforts to end hunger and malnutrition need to be scaled up and that ecosystems need to be protected for the benefit of all. To do so, the document recommends establishing a new global forum to bridge the infrastructure gap and invest in sustainable and resilient infrastructure, including transport, energy, water and sanitation services.

Irrigation, however, is not mentioned at all.

This is surprising given the fact that small-scale irrigation is essential to meet future food and nutrition security, increase rural employment, adapt to climate change and reduce continued, rapid deforestation, particularly in Africa south of the Sahara. As the latest report from the the High Level Panel of Experts (HPLE) on water for food security and nutrition clearly states, reliable access to water for both domestic and productive uses is essential to reduce undernutrition in this region, where the vast majority of smallholder farmers still depend on rain-fed agriculture yet despite high seasonal and inter-annual rainfall variability. Yields for both crops and livestock have stagnated or grown only slowly for decades; as a result, net food imports of basic staple foods have increased rapidly in order to feed a rapidly growing population. Climate change and continued population growth are expected to exacerbate food and nutrition security challenges in the region moving forward, where little progress toward reducing undernutrition has been made to date.

On the food security side, ensuring efficient and effective water management systems through irrigation is essential for raising agricultural productivity levels and helping achieve the Malabo Declarationcommitment to end hunger in Africa by 2025. Moreover, enhancing resilience of livelihoods and production systems to climate variability by increasing investments for resilience building initiatives is another key commitment of the Malabo Declaration. Irrigation has many other roles beyond ensuring stable and increased food production under more variable climate. In a recent IFPRI Discussion Paper, author Laia Domènech identifies four additional impact pathways linking irrigation to positive nutrition outcomes in Africa:

  1. Irrigation as a source of more diverse foods (through increased agricultural productivity and crop diversification);
  2. Irrigation as a source of income (from market sales and employment generation, particularly in the lean season);
  3. Irrigation as a source of water supply, sanitation, and hygiene (through multiple water use, reducing environmental enteropathy), and
  4. Irrigation as an entry point for women’s empowerment (through increased asset ownership and control over resources and reduced time spent on water collection).

Investing in irrigation is not only essential, it is also profitable. In Africa south of the Sahara, the potential is largest for small-scale irrigation which can be fit more flexibly into many different settings. For instance, a total capital investment of US$12.7 billion per year through the year 2050 could profitably develop up to 24 million hectares (ha) of irrigated agricultural land in the region without depleting water resources, up from about eight million ha in 2010. 

The time for investment is now: the region’s population deserves access to water for productive uses in order to increase food and nutrition security, increase resilience in the face of growing climate variability, and conserve remaining forested areas.
