Question

effect of global warming on agriculture​

Answer 1

Answer:

effect of global warming on agriculture

Explanation:

Crops grown in the United States are critical for the food supply here and around the world. U.S. farms supply nearly 25% of all grains (such as wheat, corn, and rice) on the global market.[4] Changes in temperature, atmospheric carbon dioxide (CO2), and the frequency and intensity of extreme weather could have significant impacts on crop yields.

For any particular crop, the effect of increased temperature will depend on the crop's optimal temperature for growth and reproduction.[1] In some areas, warming may benefit the types of crops that are typically planted there, or allow farmers to shift to crops that are currently grown in warmer areas. Conversely, if the higher temperature exceeds a crop's optimum temperature, yields will decline.  

Answer 2

Answer:

Explanation:

Climate change can affect agriculture in a variety of ways. Beyond a certain range of temperatures, warming tends to reduce yields because crops speed through their development, producing less grain in the process. And higher temperatures also interfere with the ability of plants to get and use moisture.Man’s relentless pursuit of material comfort and ‘happiness’ has

engendered an irreversible harm to the environment – statements such as

these abound environmental magazines, newspapers and the rest of the

media. Hardly a day passes without us having to hear such words as

“catastrophe”, “natural diseases”, “crisis”, etc. in the media. We hear of

calving of ice bergs in Greenland and flash floods in the American

Southwest. We also hear apocalyptic predictions made by scientists,

environmentalists and even the laymen about the coastal cities of India

getting inundated by the sea.

In a country like India where seventy percent of the population is

dependent on agriculture, it is imperative that the effect of such drastic

changes in environment are studied. Also, it is equally important that we rely

more on scientifically proven facts about global climate changes rather than

mere conjectures and exaggerations.

Effect of Climate Change on Agroiculture – An introduction

It is known that climate change is affecting agriculture in many ways.

A lot of studies have been carried out by agriculturalists, scientists and

economists on the adverse effects of climate change.

In India, agriculture and allied activities constitute the single largest
