Impact of climate change on agriculture
Despite technological advances, such as improved varieties, genetically modified organisms, and irrigation systems, weather is still a key factor in agricultural productivity, as well as soil properties and natural communities. The effect of climate on agriculture is related to variabilities in local climates rather than in global climate patterns. The Earth's average surface temperature has increased by 1.5°F {0.83°C} since 1880. Consequently, agronomists consider any assessment has to be individually consider each local area.
On the other hand, agricultural trade has grown in recent years, and now provides significant amounts of food, on a national level to major importing countries, as well as comfortable income to exporting ones. The international aspect of trade and security in terms of food implies the need to also consider the effects of climate change on a global scale.
A study published in Science suggests that, due to climate change, "southern Africa could lose more than 30% of its main crop, maize, by 2030. In South Asia losses of many regional staples, such as rice, millet and maize could top 10%".
The Intergovernmental Panel on Climate Change (IPCC) has produced several reports that have assessed the scientific literature on climate change. The IPCC Third Assessment Report, published in 2001, concluded that the poorest countries would be hardest hit, with reductions in crop yields in most tropical and sub-tropical regions due to decreased water availability, and new or changed insect pest incidence. In Africa and Latin America many rainfed crops are near their maximum temperature tolerance, so that yields are likely to fall sharply for even small climate changes; falls in agricultural productivity of up to 30% over the 21st century are projected. Marine life and the fishing industry will also be severely affected in some places.
In the long run, the climatic change could affect agriculture in several ways:
• productivity, in terms of quantity and quality of crops
• agricultural practices, through changes of water use (irrigation) and agricultural inputs such as herbicides, insecticides and fertilizers
• environmental effects, in particular in relation of frequency and intensity of soil drainage (leading to nitrogen leaching), soil erosion, reduction of crop diversity
• rural space, through the loss and gain of cultivated lands, land speculation, land renunciation, and hydraulic amenities.
• adaptation, organisms may become more or less competitive, as well as humans may develop urgency to develop more competitive organisms, such as flood resistant or salt resistant varieties of rice.
They are large uncertainties to uncover, particularly because there is lack of information on many specific local regions, and include the uncertainties on magnitude of climate change, the effects of technological changes on productivity,...

Food Ethics: Should Environmentalists Oppose Genetically Modified Food?

1512 words - 7 pages I will argue that environmentalists should not oppose genetically modified foods. Genetically modified foods or GMOs (genetically-modified organisms) are crop plants that are modified in a laboratory to enhance desired traits, to offer greater yields, to improve pest and disease resistance, to increase nutrition, or to boost tolerance to temperature extremes, drought, and salinity (The Hutchinson Encyclopedia with Atlas and Weather Guide

2591 words - 11 pages developing countries will rise by numbers. The implications of urbanization are significant for the food system. It is estimated that people living in rural areas depend on their own production for more than 60 percent of their food supply. People living in urban areas, however, depend on the market for close to 90 percent of their food supply. So every time a person moves from a rural to an urban setting, needed market supplies must increase by a factor
