Abstract

This study is based on datasets acquired from multi sources e.g. rain-gauges, satellite, reanalysis and coupled model for the region of Northwestern India. The influence of rainfall on crop production is obvious and direct. With the climate change and global warming, greenhouse gases are also showing an adverse impact on crop production. Greenhouse gases (e.g. CO2, NO2 and CH4) have shown an increasing trend over Northwestern Indian region. In recent years, rainfall has also shown an increasing trend over Northwestern India, while the production of rice and maize are reducing over the region. From eight selected sites, over Northwestern India, where rice and maize productions have reduced by 40%, with an increase in CO2, NO2 and CH4 gas emission by 5% from 1998 to 2011. The correlation from one year to another between rainfall, gas emission and crop production was not very robust throughout the study period, but seemed to be stronger for some years than others. Such trends and crop yield are attributed to rainfall, greenhouse gas emissions and to the climate variability.

印度西北部的温室气体排放、降雨和作物生产

这项研究基于从多个来源获得的数据集，如雨量计、卫星、再分析和印度西北地区的耦合模型。降雨对作物生产的影响是明显而直接的。随着气候变化和全球变暖，温室气体也对作物生产产生了不利影响。印度西北部地区的温室气体（如CO2、NO2和CH4）呈增加趋势。近年来，印度西北部的降雨量也呈增加趋势，而该地区的水稻和玉米产量正在减少。从印度西北部的八个选定地点来看，从1998年到2011年，那里的水稻和玉米产量减少了40%，二氧化碳、NO2和CH4气体排放量增加了5%。在整个研究期间，降雨、气体排放和作物产量之间的相关性在一年与另一年之间不是很强，但在某些年份似乎比其他年份更强。这种趋势和作物产量归因于降雨、温室气体排放和气候变化。

期刊介绍： The Open Ecology Journal is an open access online journal which embraces the trans-disciplinary nature of ecology, seeking to publish original research articles, reviews, letters and guest edited single topic issues representing important scientific progress from all areas of ecology and its linkages to other fields. The journal also focuses on the basic principles of the natural environment and its conservation. Contributions may be based on any taxa, natural or artificial environments, biodiversity, spatial scales, temporal scales, and methods that advance this multi-faceted and dynamic science. The Open Ecology Journal also considers empirical and theoretical studies that promote the construction of a broadly applicable conceptual framework or that present rigorous tests or novel applications of ecological theory.
