This article reviews the level of current scientific understanding regarding the impact of future change in the large-scale climate-earth system on ecosystem services. Impacts from sea level rise, ocean acidification, increases in ocean temperature, potential collapse of the thermohaline circulation; failure of the South Asia monsoon; the melting of sea ice, the Greenland Ice Sheet and the West Antarctic Ice Sheet; changes in water availability; and Amazonia forest dieback, are considered.

The conversion of marginal croplands to tree plantations, as an option to address climate change, land degradation, and irrigation water scarcity, as well as to improve the welfare of local population requires prior analysis.

Agriculture is extremely sensitive to climate and weather conditions. The resilience of our crop production systems to changes in climate can be enhanced by improved understanding impacts and responses of crops to changing climates. Several countries in Asia and Africa are at the risk of losing about 280 million tons of potential cereal production as a result of climate change factor, particularly increasing temperatures and prolonged dry periods.

Technology introduction and the intensive use of resources, particularly in smallholder farming systems, are at the core of debates about future food security and sustainable livelihoods. In Brazil, land use changes promoted by competing agricultural chains require a search for alternative modes of production for family farms. We analyse the technical and economic viability of intensification of dairy farming by smallholders in the “Balde Cheio” (Full Bucket) programme.

This paper explores the concept of homegardens and their potential functions as strategic elements in land-use planning, and adaptation and mitigation to climate change in Sri Lanka.

Agriculture production in developing countries must be increased to meet food demand for a growing population. Earlier literature suggests that sustainable land management could increase food production without degrading soil and water resources. Improved agronomic practices include organic fertilization, minimum soil disturbance, and incorporation of residues, terraces, water harvesting and conservation, and agroforestry. These practices can also deliver co-benefits in the form of reduced greenhouse gas emissions and enhanced carbon storage in soils and biomass.

Food security remains an ongoing global concern: the challenge of ensuring food availability, access, and utility for all, at all times, is yet to be met. The body of literature relating to food security is growing immensely. Land administrators are part of the discourse. Their arguments are spread disparately across academic and professional publications. The distinction between scientific work and political rhetoric is increasingly blurry: the role of land administration needs to be more concisely articulated.

Agriculture is the economic foundation of many Sub-Saharan Africa (SSA) countries, employing about 60 percent of the workforce and contributing an average of 30 percent of gross domestic product. Yet agricultural growth rates for SSA declined in the 2000 and food insecurity remains a concern, with malnourishment only dropping from 34 to 30 percent in two decades. Various projections suggest that food production must increase by 70-100 percent by 2050 to meet the demands of a world with 9 billion people and changing diets.

The 2013 Global Hunger Index (GHI) report-the eighth in an annual series- presents a multidimensional measure of national, regional, and global hunger. It shows that the world has made some progress in reducing hunger since 1990, but still has far to go. The 2013 GHI report focuses on resilience in theory and in practice. The relief and development communities have long struggled to understand why some people fare better than others when confronting stresses or shocks.

Der Bericht zum Welthunger-Index 2013 – der achte in einer jährlich erscheinenden Serie – stellt die Entwicklung des weltweiten, regionalen und nationalen Hungers mittels eines mehrdimensionalen Indexwertes dar. Er zeigt, dass die Weltgemeinschaft bei der Bekämpfung des Hungers seit 1990 gewisse Fortschritte gemacht hat, dass aber noch viel zu tun ist.

Since the early 1960s, notwithstanding dire predictions of agricultural theorists and colonial observers, agricultural growth has been strong among most Southeast Asian countries. More recently, this expansion has reached the maritime domain, with the rapid development of aquatic production through sea-based aquaculture among others. In recent territorial expansion and increase in yields for export crops has been faster than for food crops.
