The impact of climate change on agriculture

Agriculture, is the world's major source of food, fiber, forage, medicine and so on, which are necessary to human life to sustain, as well as being the world's most important issue in terms economic growth and lobar opportunity. It is utterly depends on climate and weather. Agriculture being so vulnerable to the climate change, it is therefore highly impacted by the short-term variability of the weather and long-term change of the climate. In the end of the 19 century with the beginning of 20^th as well as this modern century, climate change had increasingly become the world's important agenda, in terms global warming attributed to unimpeded greenhouse gases, such Carbon-dioxide, (CO₂ ), Methane, (CH₄), as well as acid form gaseous compounds, such Sulfuric and Nitric acid and so on. They collectively contribute, rising of temperature, falling acidic rains, heightening the sea level, and also leading heavy rainfalls.

Environment, as it is bieng the sum  total suroundings of all living things including any natural forces or other living things which provide development and growth of the environment and as well as degradation and damage of the environment   is either hastily or gradually threatened by entire above mentioned climatic elements. Subjecting these climatic aspects to agriculture as being a significant and most susceptible part of environment lead, economic devastation, diminution of food, fiber and forage production which will ultimately induce the disturbance of food security entire the world and eventually the so-called famine in both under-developing and developing countries. According to (IFPRI), the alter of the climate had effected the production of most consumable crops such as maize, rice, wheat and so on in most of the regions in the world. The gradual raising of temperature as well as undesirable rainfall, which became so favorable to the weeds, pests, and insects, which all reduce the crop yield. This therefore induced applying broad spectra pesticides, herbicides, as well as using many toxic chemicals for crop protection, which on the other hand negatively affected beneficial natural enemies,-predators, pollinators, and the human well-beings as well as all other sensitive organism which plays a significant role in the ecosystem. Achieving low profit with maximum cost is also an additional outcome of the effect, particularly in tropical and sub-tropical regions. In addition livestock, wildlife, and marine life had also been effected. According to environmental studies in University of Toronto and other international institutes the range lands for posture and feed production for livestock in some North-American countries had been reported low posture for domestic animals, particularly in prairie land of Canada.

The recurrent low rainfall in East Africa, which catalyzed consecutive droughts in the region is considerable effect of long-term change of the climate.

To sum up, the climate change had resulted high temperature, undesirable rainfall, either less or high, acidic rains, which induces some species of plants to get extinct raising see level due to melting ices and glaciers which pessimistically effects the marine species.
