Climate change will adversely affect the world agriculture in future. Rise in temperature will favour the development of population of insect pests and pathogens, which will affect the productivity of crops. Similarly due to rise in carbon dioxide (CO2) concentration and temperature, the weed population particularly those belonging to Poaceae, Cyperaceae, Fabaceae, Euphorbiaceae and Portulacaceae families will increase many fold, which will adversely affect the yield of the crops.

The rate of the decomposition of organic matter will be enhanced due to rise in temperature, thus affecting the cycling of the nutrients. This will upset the fertility status of the soil.

In spite of the resistance of many to accept transgenic plants, if we desire to abandon the use of conventional insecticides and fungicides in the industrial agriculture, we will have to accept transgenic plants of the new generation resistant against pest and diseases. However I have some reserve for transgenic plants resistant to herbicides … Some agriculture (like in Switzerland) will be also sponsored by the state. In the vicinity of large cities a new agriculture will develop; the vertical agriculture where on a small space large quantities of vegetables will be produced. Some farms will also specialize into the production of insects (for consumption). In many countries the number of smaller farms practicing “organic agriculture” respectful of the environment will be on the increase…
