Climate change is a gigantic challenge and threat for food security throughout the globe. Climate change induced by human activities either by natural system manipulation like deforestation, urbanization, industrialization, diversion of behavior for comfortable life passing and by more greenhouse gases (GHG) emission for calmness in life. On the other hand with the calmness in life, changed the Earth’s atmosphere and produced aerosols (small particles), and cloudiness in the atmosphere. These aerosol caused global warming and effected agricultural productivity at regional level. There may be a vigorous growth of some crops in raised CO2 conditions, but there is a trade-off because as temperature rises seed production may be drop especially of maize and soybean in tropical regions. Shifting, vanishing and endangering of the marginal crops is increasing rapidly which a big challenge and threats towards food security. Average temperature of the earth, which has been increasing for many years.
In this Context present study was investigated at reginal level of district swat to evaluate the impact of changing climate on crop productivity at various location and crop responses to the changing climate. It was concluded and suggested that production of maize, soybean tomato, cucumber, squashes, peas, French bean, canola and pulses are vulnerable to extreme temperature and drought stress. Therefore climate change is a real fact confronting to agriculture productivity. So proper management with biochar, soil amendments, charcoal and other organic matter will might be promote root density, and will result in more number of roots having more water and nutrients absorption and will ultimately reduce the impact of changing climate.
