Change in cropping practices is required to address the food security issues in Africa. Yet, testing of the performance of such changes, in particular at large scales, often needs significant investments.

Free distribution of a technology can be an effective development policy instrument if its adoption is socially inefficient and hampered by affordability constraints. Improved cookstoves may be such a case: they generate high environmental and public health returns, but adoption is generally low.

This paper is based on a field study carried out in 2015 in two coastal ecotourism areas in The Gambia — Kartong and Tanji. The study investigated sustainability communication by tourism service providers in the context of climate change and ecovillage design education (EDE).

Providing electricity to the unconnected 1.1 billion people in developing countries is one of the top political priorities of the international community, yet the costs of reaching this objective are very high.

To achieve food security for all, new resource policies for sustainable land and water use are needed. Land, water, and energy need to be considered jointly in policies, not in isolation.

As crop straw and firewood are generated as by-products of food production systems, they are perceived to be sustainable energy sources that do not threaten food security by Chinese government for a long time.

The focus of the analysis is on nexus issues among energy use, incomes, employment, investment decisions, and agricultural production for meeting food and feed demands, as well as health-related effects on rural households.

This paper reviews the effect of natural disasters on human mobility or migration. Although there is an increase of natural disasters and migration recently and more patterns to observe, the relationship remains complex.

One of the major challenges of the 21st century is to achieve food security under marked shifts in climatic risks and roughly a doubling in food demand by 2050 compared to present.

The ever-growing population of India, along with the increasing competition for water for productive uses in different sectors – especially irrigated agriculture and related local water systems and drainage – poses a challenge in an effort to improve water quality and sanitation.
