    Food aid is a critical component of the global food system, particularly when emergency situations arise. For the first time, we evaluate the water footprint of food aid. To do this, we draw on food aid data from theWorld Food Programme and virtual water content estimates from WaterStat. We find that the total water footprint of food aid was 10 km3 in 2005, which represents approximately 0.5% of the water footprint of food trade and 2.0% of the water footprint of land grabbing (i.e., water appropriation associated with large agricultural land deals).

    In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

    The Sahel has been the focus of scientific interest in environmental-human dynamics and interactions. The objective of the present study is to contribute to the recent debate on the re-greening of Sahel. The paper examines the dynamics of barren land in the Sahel of Burkina Faso through analysis of remotely-sensed and rainfall data from 1975–2011. Discussions with farmers and land management staff have helped to understand the anthropogenic efforts toward soil restoration to enable the subsistence farming agriculture.

    Climatic stress and anthropogenic disturbances have caused significant environmental changes in the Sahel. In this context, the importance of soil is often underrepresented. Thus, we analyze and discuss the interdependency of soil and vegetation by classifying soil types and its woody cover for a region in the Senegalese Ferlo. Clustering of 28 soil parameters led to four soil types which correspond with local Wolof denotations: Dek, Bowel, Dior and Bardial.

    Crown diameter and tree density were measured in 52 communities in the Sudan-Sahel using satellite imagery to determine the relationships between rainfall and distance from community center to crown size diameter and tree density. As distance from the community center increased, tree density and crown diameter decreased. As rainfall increased, tree density decreased while crown diameter increased. Distance from the community center is a proxy for age since urbanization and our results indicate that older parts of communities show longer and more consistent tree management.

    There is growing evidence that investing in developing countries’ agricultural sector is among the most efficient ways to reduce poverty and hunger. Agricultural investments can generate a wide range of developmental benefits, but these benefits cannot be expected to arise automatically and some forms of large-scale investment carry risks for host countries. Although there has been much debate about the potential benefits and risks of international investment, there is a lack of systematic evidence on the actual impacts on the host country and their determinants.

    This thematic study explores the links between the right to food and natural resources governance. It covers a range of issues of which access to resources and assets, land, water, and the recommendation to protect ecological sustainability for sustainable management of natural resources are primary.
