ABSTRACT
Investment to increase production in drylands has been limited, at least in part due to the popular misconception that drylands are empty, barren places (White et al., 2002). Development and research have focused on high-potential areas with the possible expansion of irrigated areas and intensification of irrigated agriculture. However, increasing numbers of people are living in dryland areas as a result of population growth. Hazell (1998) stated that it is becoming increasingly clear that, on poverty and environmental grounds alone, more attention will have to be given by both national governments and international development agencies to less-favoured lands in setting priorities for policy and public investments. At the same time, evidence of productivity gains, poverty reduction, and environmental benefits are required to encourage the necessary funding in dryland regions. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781849773744/65c2c63a-5adc-4ca3-89cb-094580b38b8d/content/figu_4_C.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
