Recent experience has shown that as countries get richer, nutritional status does not necessarily improve. In a recent article in the journal The Lancet, IFPRI researchers and others explain that creating the right conditions for nutritional advances often requires political action. The feature article in this issue of Insights looks at how some developing countries and regions—Ghana, Peru, Thailand, and the state of Maharashtra, India—have made nutrition a political priority and how they’ve turned political commitments into widespread changes on the ground.

Brésil

This report identifies the links among economic growth, poverty alleviation, and natural resource degradation in Brazil. It examines the effects of (1) a major devaluation of the Brazilian real (R$); (2) improvements of infrastructure in the Amazon to link it with the rest of Brazil and bordering countries; (3) modification of land tenure regimes in the Amazon agricultural frontier; (4) adoption of technological change in agriculture both inside and outside the Amazon; and (5) fiscal mechanisms to reduce deforestation." -- from Author's Abstract

Improving the long-term sustainability and resilience of smallholder agriculture in Africa is highly dependent on conserving or improving the quality of the natural resource. Conservation agriculture is conceived around more integrated and effective management strategies for provisioning both food and other ecosystem services. If unattended to, land degradation would reduce agricultural productivity and increase pressure on marginal environments in the Tigray highlands of Ethiopia, adversely affecting food security and livelihoods of smallholder farmers.

Ghana

"An economywide, multimarket model is constructed for Ghana and the effects of agricultural soil erosion on crop yields are explicitly modeled at the subnational regional level for eight main staple crops. The model is used to evaluate the aggregate economic costs of soil erosion by taking into account economywide linkages between production and consumption, across sectors and agricultural subsectors. To fill a gap in the literature regarding economic cost analysis of soil erosion, this paper also analyzes the poverty implications of land degradation.

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....

Recent trends in agricultural growth and food security in Eastern and Central Africa (ECA) have been discouraging. With very low labor productivity, yields, and growth rates, agriculture is unable to keep up with population growth or achieve the type of pro-poor growth needed to reduce poverty dramatically.Yet agriculture accounts for about half of the region’s gross domestic product (GDP) and is the main source of livelihood for the majority of the population. Behind this gloomy picture, however, lies agriculture’s potential to be the engine for growth in ECA.

The 2014 Global Hunger Index (GHI) report—the ninth in an annual series—presents a multidimensional measure of national, regional, and global hunger. It shows that the world has made progress in reducing hunger since 1990, but still has far to go, with levels of hunger remaining “alarming” or “extremely alarming” in 16 countries. This year’s report focuses on a critical aspect of hunger that is often overlooked: hidden hunger. Also known as micronutrient deficiency, hidden hunger affects more than an estimated 2 billion people globally.
