AMU professor delivers lecture at an international congress

ALIGARH  : “The trend of global warming is continuing and in future, the world would be facing great challenges of weather extremes like intense drought, flooding, flash and heavy rainfall, melting of ice and increasing of sea-level, catastrophic storms and declining of biodiversity,” said Prof Nizamuddin Khan, Department of Geography, Aligarh Muslim University, while delivering a lecture on “Impact of Climate Change on Agriculture in India” in the first International Hybrid Congress on “Geodiversity, Geoheritage, Geotourism, Geoeducation, Geoparks and Sustainable Development Goals”, held in Safi, Marrakech (Morocco), recently.

Prof. Khan highlighted current issues of increasing temperature at global level and pointed out that global temperature rose up about 1.3 degree centigrade during 1901 to 2020. The last decade (2011-2020) was the warmest on record and each of the last four decades has been warmer than any previous decade since 1850.

He said the climate change has impacted agriculture in different ways in world and decline in agricultural productivity and reduction in cropped areas is the most important effects of climate change. It is estimated by Cline W. (2007) in Global Warming and Agriculture that agricultural productivity would decline from 15 to 25 percent in tropical developing countries, including India, in all continents due to extreme weather like intense drought and abnormal rainfall.

Prof. Khan suggested development of climate-change-resilient agriculture as an important measure to fight with climate change effects.
