In the past, it was believed that global warming has good effect on agriculture and food supply. The reason is the will be higher carbon-dioxide from climate change, so that it will help the plants for photosynthesis and increase the agricultural production and food supply. However, recent studies say that hotter weather results negative effects on agriculture and food supply. Hot condition will cause more droughts, floods, landslides and storms. Then, winter will be shortened while summer will be longer and severe. That will be followed with heavy rain, big storm, heavy snowfall, high sea level, and higher coastal erosion.
However, the food supply and production level is expected to rise continually. The real condition is longer drought makes more problems in agriculture. It reduces some productions of staple food. Also, one of the effects of global warming the south west USA is lacking of more water supplies in coming days. That area becomes dryer so that it is below the standard agricultural production. Following a report of weather modification, the snow covered Sierra Mountains can decrease in near future by up to 60-90%. As a result, there will be frightening problem in water supply and that area is not suitable for agricultural production. More states have said that there will be reduction in agriculture and food supply due to effects of global warming.
Researchers have conducted some studies to create new and more sustainable farming methods which contribute to make healthier and chemical free food for customers. Also, it is expected that the findings will concern about the environment, effects of too much chemical fertilizer on food use on our own health, and the quality of the land. In addition, the innovation should include the pest and disease control in resulting improvements and sustainable farming. The answers come into biological control, pest management, and biotechnology. They are specifically used to achieve more ecologically awareness at the local farm level.
Science, renewable technologies, and natural biological control are combined to provide the most resource-poor farmers. One new innovation is using acoustic hand-held device which works by broadcasting a digitally stored sad call to make a chaos environment in the farming area. That will cause the birds to feel danger and directly fly away. Some trials show this method is almost 100% effective. Then, biopepticides are developed to provide the agricultural products farmers and growers with pest and disease control, yield improvement and preserve their land's quality. They are important to approach the controlling pests and increasing crop production.
Agriculture can be seen as the core industry in a country so that it has been improved optimality. Biotechnology is an alternative method which is recommended to apply. This is a technique where living organisms are changed to make or modify agricultural products. It helps also to improve crops and develop microbes for specific purposes in agricultural processes. Researchers also introduce genetic engineering which is part of agricultural biotechnology to manipulate genes and transform them on almost all plant species.
With biotechnology, the food production cost is cheaper and easy to taking care the plantation. There are some specific herbicide tolerant crops which have been managed so that the weeds are controlled more efficiently. This method helps to control pests more reliable and reduce the need for synthetic pesticides since crops become resist to several diseases and insect pests. Another method introduced is Phytore mediation. This is a process where plants detoxify pollutants in the soil, absorb and accumulate polluting substances out of the soil. Hence, this can at least keep and improve the soil quality.
