Efficiency of Fertilizer Nitrogen in Cereal Production: Retrospects and Prospects
TL;DR: In this article, the authors estimate that 50 to 70% more cereal grain will be required by 2050 to feed 9.3 billion people, which will require increased use of N of similar magnitude if the efficiency with which N is used by the crop is not improved.
Book ChapterDOI
Regional vulnerability of climate change impacts on Asian rice production and scope for adaptation
Reiner Wassmann,S. V. K. Jagadish,K. Sumfleth,Himanshu Pathak,G. Howell,Abdelbagi M. Ismail,Rachid Serraj,Edilberto D. Redoña,Rakesh Singh,Sigrid Heuer +9 more
TL;DR: In this article, the authors assess the spatial and temporal vulnerabilities of different rice production systems to climate change impacts in Asia and conclude that geo-spatial vulnerability assessments may become crucial for planning targeted adaptation programs, but that policy frameworks are needed for their implementation.
Journal ArticleDOI
How extensive are yield declines in long-term rice-wheat experiments in Asia?
Jagdish K. Ladha,David Dawe,Himanshu Pathak,A. T. Padre,R. L. Yadav,Bijay Singh,Yadvinder Singh,Y.V. Singh,P. P. Singh,Amitabh Kundu,R. Sakal,N. Ram,A. P. Regmi,S. K. Gami,A. L. Bhandari,R. Amin,C. R. Yadav,E. M. Bhattarai,S. K. Das,H.P Aggarwal,R. K. Gupta,Peter Hobbs +21 more
TL;DR: In this paper, the authors analyzed 33 rice-wheat LTE in the Indo-Gangetic Plains (IGP) of South Asia, non-IGP in India, and China to investigate the extent of yield stagnation or decline and identify possible causes of yield decline.
Book ChapterDOI
Climate change affecting rice production: the physiological and agronomic basis for possible adaptation strategies
Reiner Wassmann,S. V. K. Jagadish,Sigrid Heuer,Abdelbagi M. Ismail,Edilberto D. Redoña,Rachid Serraj,Rakesh Singh,G. Howell,Himanshu Pathak,K. Sumfleth +9 more
TL;DR: In this article, a review of the adaptation strategies in rice production to climate change is presented, where the authors discuss the current state of knowledge on damage mechanism for rice plants as well as possible developments in germplasm and crop management technologies to overcome production losses.
Journal ArticleDOI
Emission of Air Pollutants from Crop Residue Burning in India
TL;DR: In this article, a state-wise inventory of crop residue burnt in India and the air pollutants emitted was prepared using the Inter-Governmental Panel on Climate Change (IPCC) national inventory preparation guidelines for the year 2008-09.
