Effects of Global Warming on Agriculture

Our demands for more and more food are rising on day by day due to increasing human population. The supply of food mainly comes from agriculture. But the increasing temperature followed by changes in climatic conditions due to global warming is sure to damage it.

Global warming may cause drought and outbreak of insects. Both of these conditions are damaging to agriculture. Higher temperature accelerates the maturation of earlier disease causing agents and their vectors. All these conditions cause damage to and failure of crops.

Climatic factors like temperature, wind, relative humidity, rain fall etc. have direct effects on agriculture. Since global warming is changing the global climates, adverse changes in agriculture and its production is bound to occur. On the other hand changing frequencies of natural disasters such as floods,tornado, cyclones, hurricanes, landslides, mud-flows etc. tend to vanish out our crops besides causing great losses to life and property. Hail storms, wind storms and also, fog and mist cause serious damages to our crops each year. In many parts of India, farmers go on demonstration and road jams demanding compensations from the government whenever their crops are damaged due to any of these reasons.
