This study aims to systematically establish whether costs of irrigation projects in SSA are truly high, determine the factors which influence costs and recommend cost-reducing options in order make irrigation investments in SSA more attractive. The study analyzes 314 irrigation projects implement...

The authors reflect on the theory and process of creating effective strategies for adaptive river basin management. We formulate our framework from observations of responses to environmental and hydrological change in the Great Ruaha River in Tanzania. We find that problems occur in the pursuit o...

Argues that single irrigation systems managed by autonomous system-specific organizations accountable to their customers, perform better and are more sustainable than those managed by agencies dependent on the government, or by agencies responsible for multiple systems. Selected cases are reviewe...

High irrigation investment costs together with declining world prices for food and the failures of a number of high profile past irrigation projects are the main reasons for the reluctance of development agencies and governments in Sub-Saharan Africa to invest more resources in irrigation. This s...

This paper uses 314 irrigation projects implemented from 1960-2000 in six regions worldwide to identify: (1) whether the perception of high cost of irrigation projects in SSA can be empirically supported; (2) what factors determine the costs and performance of irrigation projects; and (3) whether...
