The methods consisted of (a) segmenting the 952-band MFDC based not only on elevation-precipitation-temperature zones but on major and minor irrigated command area boundaries obtained from India's Central Board of Irrigation and Power (CBIP), (b) developing a large ideal spectral data bank (...

in Fig.5, with a large majority of countries clustering on the upper right side of the plot. This area includes 80% of the countries and contains the largest agricultural water consumers (e.g. China, India, Spain, Italy, Egypt or the United States, among others). In the case of ...
Soil nutrient pool has to offset the negative balance of N and K, hence there is an expected mining of nutrient from the soil reserve in the research area. The management options / policy interventions to mitigate this mining by manipulating all inputs and outputs in a judicious way with an...
India, which has nearly 30 % of global annualized irrigated areas (AIAs), and is the leading irrigated area country in the World, along with China, was chosen for the study. Irrigated areas were derived for nominal year 2000 using time-series remote sensing at two spatial resolutions: (a)...
(10) Just during the last two decades, the irrigated harvested area in Africa, Asia and South America has doubled from about 72 million ha to 139 million ha,Table 4. (4) By 1990, the totalirrigated areais estimated to be about 273 million ha, which represents about 30% of the ...
In India, increasing groundwater irrigated area has allowed to sustain the growth of agricultural production since 40 years and to meet the need of a growing population11,35. In the Deccan plateau in South India, the development of submersible pump technology allowed millions of small farmers, ty...

Irrigated agriculture, contributing two-fifths of global agricultural production from one-fifth cropped area, is under stress due to associated waterlogging and soil salinity problems. Current annual crop productivity losses due to irrig... SK Kamra,S Kumar,N Kumar,... 被引量: 0发表: 2019年 Dra...
In this study, we evaluated how the irrigation expansion around the city affected the urban heat moist stress, by analyzing the surrounding irrigation area change and moist heat stress change of more than 1000 cities in China and India. We found that although the irrigation area expansion reduced...
