Water, sanitation, and hygiene can have a profound effect on health and nutrition. A growing base of evidence on the link between sanitation, child height, and well-being has come at an opportune time, when the issue of sanitation and nutrition in developing countries has moved to the top of the post-2015 development agenda.

The trend is inescapable: more and more people in the developing world are living in the cities. By 2020, the number of people living in developing countries will grow from 4.9 billion to 6.8 billion. Ninety percent of this increase will be in rapidly expanding cities and towns. More than half the population of Africa and Asia will live in urban areas by 2020. More than three-quarters of Latin Americans already do.

The second of three books in IFPRI's climate change in Africa series, East African Agriculture and Climate Change: A Comprehensive Analysis examines the food security threats facing 10 of the countries that make up east and central Africa - Burundi, Democratic Republic of Congo, Eritrea, Kenya, Madagascar, Rwanda, Sudan, Tanzania, and Uganda - and explores how climate change will increase the efforts needed to achieve sustainable food security throughout the region. East Africa's populations is expected to grow at least through mid-century. The region will also see income growth.

A large body of literature makes the argument that commercialization of agriculture has mainly negative effects on the employment, incomes, food production and consumption, health, and nutrition of the poor.

How can family farmers best contribute to their country’s agriculture needs as well as broader development goals? First, we should determine which farmers can be profitable and assist them in doing so. Second, for those who aren’t profitable, we need to help them shift to other economic pursuits.

This study employs IFPRI’s IMPACT model to generate projections of global fi sh supply and demand. IMPACT covers the world in 115 model regions for a range of agricultural commodities, to which fi sh and fi sh products are added for this study. As is the case with most global modeling work, an important value that IMPACT brings to this study is an internally consistent framework for analyzing and organizing the underlying data.

"Biodiversity provides essential components of healthy environments and sustainable livelihoods. One key component of biodiversity is agrobiodiversity—that is, the cultivated plants and animals that form the raw material of agriculture, the wild foods and other products gathered by rural populations within traditional subsistence systems, and organisms such as pollinators and soil biota... Agrobiodiversity used and conserved in a livelihood context can directly contribute to nutrition, health, and income generation...

Policy Analysis for Sustainable Land Management and Food Security in Ethiopia presents a bioeconomic model of this less- favored area in the Ethiopian highlands. The main reason for selecting this case study area is the unique availability of both biophysical and socioeconomic data covering a period of 15 to 20 years.The data provides a valuable opportunity to analyze the relationships between population pressure, poverty, and land degradation and to test policies for reducing vulnerability and improving sustainable management of the resource base....
