Such collaboration can improve value chain efficiency and may also begin to address some of the ‘wicked problem’ characteristics of food insecurity.

Today, almost 33 percent of the population of sub-Saharan Africa (SSA), or close to 200 million people, is undernourished, of which close to 60 percent are in countries affected by conflicts.

This is a chapter in a book entitled "Agricultural Investment and Productivity: Building Sustainability in East Africa" edited by Gunnar Köhlin and Randall Bluffstone, 2011.

This chapter aims to contribute to the literature on soil and water conservation (SWC) by decomposing productivity into technology and technical efficiency (TE) effects. A firm is said to be technically inefficient if it produces less output from a given input bundle than the maximum output that can be attained from the input bundle at the current level of technology.

This paper investigates the effects of crop genetic diversity on farm productivity and production risk in the highlands of Ethiopia.

We examine the driving forces behind farm households’ decisions to adapt to climate change, and the impact of adaptation on farm households’ food productivity.
