COLOMBO, Jun 5, 2012 (IPS) – When it comes to expressing the threat to food security posed by changing climate patterns and extreme weather events in Asia and the Pacific, the Asian Development Bank (ADB) does not mince its words. The ADB study looked at areas that could affect food security, such as trade policies, development, the demand for food and resource management and possible mitigation efforts.
As ground water supplies dry up, the threat of rising salinity emerges as yet another obstacle to food production and security. It tagged climate change as a key player in determining food security levels, as interventions needed to stem the impacts of global warming go beyond national borders and surpass the authority of any single government.
The Global Agriculture Development Director of DuPont Pioneer, Lystra Antoine, has asked food producers and other stakeholders in the agricultural value chain to support efforts to combat the threat of food scarcity. She repeated the call for agriculture in developing countries to undergo significant transformation in order to meet the related challenges of achieving food security and responding to climate change. One third of the world's food-producing land has been lost in the past 40 years as a result of soil degradation, putting global food security at risk. UQ School of Agriculture and Food Sciences researcher Dr Peter Kopittke said the increasing human population and continuing degradation of farm soils has made food security a critical issue. Sown areas are not enough to provide nine billion people with food and should be increased. According to researches, the countries depending on food imports, including Latin America, North Africa and the Middle East, may suffer most of all. By 2050, food production must increase by 70 per cent, but land resources and in particular water, are insufficient for this plan.

Based on scientific principles, one can say that the drought in the U.S and Russia, the increase in wheat prices in world markets and other disturbing facts related to the food crisis will be more obvious during the next five years. Lack of food rich in essential vitamins weakens the immune system, creating the conditions for catching infectious diseases, preventing their physical and mental development, reducing efficiency and increasing the risk of premature death. Along with the development of domestic production, the country is taking measures to fully provide itself with foodstuffs imported into the country. Food production and other sectors such as energy production will face serious competition over water. Experts say that Africa's extensive land subdivision is emerging as a significant threat to food security. London scientists say overweight people are a threat to future food security and obesity must be tackled to reduce our ecological footprint. Overweight populations could have the same implications for world food energy demands as an extra one billion people, researchers say after examining the average weight of adults across the globe. Scientists from the London School of Hygiene and Tropical Medicine (LSHTM) say that tackling population weight is crucial for food security and ecological sustainability. Though Sri Lanka is yet to experience protracted and deadly food shortages due to changing weather patterns, recent experiences have shown that its vital rice harvest does fluctuate wildly depending on rainfall. Terraviva talks to Giuseppe Sala, CEO of EXPO Milano 2015 Expo Milano 2015 is in Rio to kick off its global dialogue on food and energy. Another risk to food security is the genetic erosion in agricultural and livestock biodiversity.

In order to solve the hunger and food security problem it is necessary to make radical changes in the Azerbaijani and world food systems. Experts say that Africa's extensive land subdivision is emerging as a significant threat to food security. If one consumes 2,200 instead of 3,000 calories, the water economy will decrease three to five fold.
Yehiya pointed out that overuse of fertiliser has made the land less productive while the demand for food is likely to rise in the future, putting even more pressure on producers. Lystra Antoine, who was speaking at a programme promotion of the Ghana Advanced Maize Seed Adoption Programme (GAMSAP) organised by the USAID and DuPont Pioneer in Kumasi, urged all stakeholders in the agricultural sector to see this need as a shared responsibility and contribute to ensure food security. The UN Millennium Development Goals are the initiatives aimed at achieving food security in the world.
It can be concluded that the prevention of the dual use or unusable agricultural products, changes in nutrition and the implementation of these measures would help to prevent hunger and ensure food security.
The population is expected to increase by two billion people over the next 40 years, which certainly will lead to a greater need for food.
