摘要

农业是最依赖天气的人类活动，因此气候变化显著影响农业生产力。在本研究中，试图对现有文献进行审查，以记录和评估印度各种作物的预计产量与-à-vis实际产量的比较。研究发现，大多数研究预测，到2020年及未来，由于气候变化，农作物产量将下降。然而，到目前为止，印度各种作物的实际产量呈增长趋势。发布和采用作物新品种、扩大灌溉面积、使用更多化学品和化肥、提高农业作业机械化等适应措施有助于提高作物产量。因此，政府应加强这些措施以促进可持续农业。

Observed vis-à-vis projected crops yield in India in the context of climate change

Agriculture is the most weather-dependent human activity and hence climate change significantly impacts agricultural productivity. In the present study, an attempt has been made to review the existing literature to document and assess the projected crops yield vis-à-vis actual yield of various crops in India. It has been found that most of the studies have projected decline in yield of crops due to climate change up to 2020 and in future. However, actual yield of various crops in India has shown increasing trend till date. Adaptation measures like the release and adoption of new varieties of crops and increase in area under irrigation, use of more chemicals and fertilizers, improved mechanization of agricultural operations, etc. have contributed in enhancing the crop yield. Thus, such measures should be strengthened by the Government for sustainable agriculture.

期刊介绍： Current Science, published every fortnight by the Association, in collaboration with the Indian Academy of Sciences, is the leading interdisciplinary science journal from India. It was started in 1932 by the then stalwarts of Indian science such as CV Raman, Birbal Sahni, Meghnad Saha, Martin Foster and S.S. Bhatnagar. In 2011, the journal completed one hundred volumes. The journal is intended as a medium for communication and discussion of important issues that concern science and scientific activities. Besides full length research articles and shorter research communications, the journal publishes review articles, scientific correspondence and commentaries, news and views, comments on recently published research papers, opinions on scientific activity, articles on universities, Indian laboratories and institutions, interviews with scientists, personal information, book reviews, etc. It is also a forum to discuss issues and problems faced by science and scientists and an effective medium of interaction among scientists in the country and abroad. Current Science is read by a large community of scientists and the circulation has been continuously going up. Current Science publishes special sections on diverse and topical themes of interest and this has served as a platform for the scientific fraternity to get their work acknowledged and highlighted. Some of the special sections that have been well received in the recent past include remote sensing, waves and symmetry, seismology in India, nanomaterials, AIDS, Alzheimer''s disease, molecular biology of ageing, cancer, cardiovascular diseases, Indian monsoon, water, transport, and mountain weather forecasting in India, to name a few. Contributions to these special issues ‘which receive widespread attention’ are from leading scientists in India and abroad.
