The Southern African Development Community’s (SADC) water and energy sectors are under increasing pressure due to population growth and agricultural and industrial development. Climate change is also negatively impacting on the region’s water and energy resources. As the majority of SADC’s population lives in poverty, regional development and integration are underpinned by water and energy security as the watercourses in the region are transboundary in nature. This paper reviews the region’s water and energy resources and recommends policies based on the water–energy nexus approach.

This chapter spells out the theoretical framework for the discussion and case studies of the book. First, it provides precise definitions of technological change and classify technological change into different types based on their factor intensities. The discussion starts off with a single farm household. Two key concepts for understanding how that household will respond to technological changes are economic incentives and constraints. The former relates to how new technologies influence the economic return of different activities.

Reliance on rainfall for agriculture and increased climate change and variability pose growing production risks in developing countries. Agriculture in Sub-Saharan Africa is dominated by smallholder farmers who depend mainly on rain-fed agriculture, putting food security at both household and national levels at risk, especially in the event of drought. Investment in smallholder irrigation becomes a priority in developing countries if food security and national development goals are to be met, as their economies are agro-based.

The historical legacy in South Africa of apartheid and the resulting discriminatory policies and power imbalances are critical to understanding how water is managed and allocated, and how people participate in designated water governance structures. The progressive post-apartheid National Water Act (NWA) is the principal legal instrument related to water governance which has broadly embraced the principles of Integrated Water Resources Management (IWRM).

Groundwater management practices need to take hydrogeology, the agro-climate and demand for groundwater into account. Since agroclimatic zones have already been demarcated by the Government of India, it would aid policy makers to understand the status of groundwater recharge and discharge in each agroclimatic zone. However, developing effective policies to manage groundwater at agroclimatic zone and state levels is constrained due to a paucity of temporal data and information.

A sustainable food future will require reductions in greenhouse gas emissions from agriculture even as the world produces substantially more food. The production of rice, the staple crop for the majority of the world’s population, emits large quantities of methane, a potent greenhouse gas. According to various governments, global rice production emits 500 million tons of greenhouse gases (carbon dioxide equivalent) per year—or at least 10 percent of total agricultural emissions.

In Senegal, concern about large-scale land acquisitions has been growing since 2000. Senegalese agriculture has long relied on small-scale family holdings and extensive agriculture. But the current population growth rate, combined with rapid urban development and natural resources degradation, have inevitably changed the game.

This rangelands management framework is a product of a rapid pastoralist-led rangeland health assessment that was conducted in three sampled districts of Karamoja; Moroto, Napak and Kotido.

Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future.

Le Niger est probablement le pays sahélien disposant du corpus juridique et du dispositif institutionnel le plus élaboré pour prémunir les pasteurs contre l’accaparement des terres pastorales. Ceci ne suffit hélas pas à endiguer le phénomène.

This study investigates today’s plant species richness and composition in cultivated and recently abandoned
arable land of Kosovo. Relationships between these aspects of vegetation and both environmental features
and agricultural management measures are studied at the regional and plot scale. In 2006, 432 vegetation relevés
with a standard plot size of 25 m² were recorded in cultivated fields. In 2007, data collection focussed on 41 plots
in arable fields that had been abandoned the year before. With respect to the environment, data analysis accounts
