Improving water security for the poor
Sustaining growth through water security
The challenge
The Awash is a large and complex river basin, home to around 18 million people and many different water users. The basin is an important region for Ethiopia’s economy; its water resources support urban areas, manufacturing, rural households, wetlands, agriculture and pastoralist livelihoods.
Water use in the basin is already high and irrigation schemes are expanding. Manufacturing and agriculture are more concentrated at the upper end of the basin, resulting in pollution and water shortages for the downstream populations, including the agro-pastoralists and pastoralists.
In 2015/16 the Awash basin experienced the worst drought in over 30 years, which had a severe impact on livelihoods, economic productivity and food security in the basin.
The observatory
Our research will provide new evidence on how water risks, such as drought, slow down a country’s economic growth.
The link between economic growth (mostly upstream in the basin) and the multidimensional poverty experienced by women, men and children associated with these changes in water security (mostly downstream) is not well understood.
We will model the trade-offs between water security for economic development and human development within the basin. Our work will help identify combinations and sequences of investment in water management to support both economic growth and poverty reduction.
Research questions
- What evidence is there for water-related economic drag in the Awash basin?
- Using a risk-based approach, what are the appropriate levels, combinations and sequences of investment in multi-sector water management and efficiency to support both economic and human development?
- How can the trade-offs between large-scale productive water uses and water security for household water use and livelihoods be managed as part of Ethiopia’s development?
