BACKGROUND: Maize is the most important staple food in Kenya; any reduction in production and yield therefore often becomes a national food security concern. To address the challenge posed by the maize stem borer, the Insect Resistant Maize for Africa (IRMA) agricultural biotechnology public-private partnership (PPP) project was launched in 1999. There were, however, pre-existing concerns regarding the use of genetic engineering in crop production and skepticism about private sector involvement.

BackgroundGrasslands are a major part of the global ecosystem, covering 37 % of the earth's terrestrial area. For a variety of reasons, mostly related to overgrazing and the resulting problems of soil erosion and weed encroachment, many of the world's natural grasslands are in poor condition and showing signs of degradation. This review examines their contribution to global food supply and to combating climate change.ScopeGrasslands make a significant contribution to food security through providing part of the feed requirements of ruminants used for meat and milk production.

Land has a cultural value in Nigeria in that its ownership cements
the relationship of the owner with the community. But more
importantly, land resource is critical to the livelihood of rural
farmers because they depend on it for income and food supply.
It is therefore important that it is sustainably managed and
efficiently used. This study investigated the ownership pattern
of land among the farming families in the study area and the
attitude towards its management. It adopted the farming and

Climate change and recurrent drought in many of the world's dry places continue to inspire the search for economically attractive measures to conserve water. This study analyzes water conservation practices in irrigated agriculture in a sub-basin in North America's Rio Grande. A method is developed to estimate water savings in irrigated agriculture that result from public subsidies to farmers who convert from surface to drip irrigation. The method accounts for economic incentives affecting farmers' choices on irrigation technology, crop mix, water application, and water depletion.

[Formula: see text] [ Martin A. J. Parry ] The balance between the supply and demand of the major food crops is fragile, fueling concerns for long‐term global food security. The rising population, increasing wealth and a proliferation of non‐food uses (e.g. bioenergy) has led to growing demands on agriculture, while increased production is limited by greater urbanization, and the degradation of land. Furthermore, global climate change with increasing temperatures and lower, more erratic rainfall is projected to decrease agricultural yields.

The United Nations Convention to Combat Desertification (UNCCD) remains the only ‘Rio Convention’ that is not well served by the scientific community and lacks the equivalent of an IPCC (Intergovernmental Panel on Climate Change) or the proposed IPBES (Intergovernmental Science–Policy Platform on Biodiversity and Ecosystem Services).

The global poor often prioritise immediate hazards of food insecurity over temporally more distant risks like global warming. Yet the influence of socio-economic factors, temporal and spatial distance on risk perception remains under-researched. Data on risk perception and response were collected from two sets of Indian villages. Participatory approaches were used to investigate variations by socio-economic status, food security, age and gender. Villagers’ risk priorities reflected clear spatial and temporal patterns depending on land ownership, community group and education levels.
