Although irrigation in Africa has the potential to boost agricultural productivities by at least 50%, food production on the continent is almost entirely rainfed. The area equipped for irrigation, currently slightly more than 13 million hectares, makes up just 6% of the total cultivated area....

Smallholder irrigation may considerably contribute to agricultural productivity growth in Sub-Saharan Africa. However, the full potential of expanding smallholder irrigation under alternative irrigation technologies is not known. This paper presents a study to assess the irrigation expansion...

As the global population grows and incomes in poor countries rise, so too, will the demand for food, placing additional pressure on sustainable food production. Climate change adds a further challenge, as changes in temperature and precipitation threaten agricultural productivity and the...

Agricultural water productivity (WP) has been recognized as an important indicator of agricultural water management. This study assesses the WP for irrigated (WPI) and rainfed (WPR) crops in the Yellow River Basin (YRB) in China. WPI and WPR are calculated for major crops (corn, wheat, rice, and...

The most recent (2010–2011) drought in the arid and semiarid lowlands (ASAL) of the Horn of Africa has rendered over 13 million people in need of food, and caused a devastating famine in southern Somalia. The drought has also raised concerns that pastoralist livelihoods in this region are...

Despite the rise of targeted input subsidy programs in Africa over the last decade, several questions remain as to whether low and variable soil fertility, frequent drought, and high fertilizer prices render fertilizer unprofitable for large subpopulations of African farmers. To examine these...

The recent surge in food prices around the world may reverse the gains of reducing hunger and poverty in the recent years. This paper employs factor and sequential typology analysis using data for 175 countries to identify groups of countries categorized according to four measures of food...
