It has been reported that in different regions and sowing dates, the response of crops to past climate change is not the same, due to different rates of decrease/increase in each climatic variable at different regions and months of year. This study was aimed to assess the effect of individual versus simultaneous changes in solar radiation (S), precipitation (P) and temperature (T) on rainf...

The goal of this study was to map rainfed and irrigated rice-fallow cropland areas across South Asia, using MODIS 250 m time-series data and identify where the farming system may be intensified by the inclusion of a shortseason crop during the fallow period. Rice-fallow cropland areas are those areas where rice is grown during the kharif growing season (June–October), followed by a fallow durin...

The main objective of this study is to present an improved modeling technique called Vegetation ET (VegET) that integrates commonly used water balance algorithms with remotely sensed Land Surface Phenology (LSP) parameter to conduct operational vegetation water balance modeling of rainfed systems at the LSP’s spatial scale using readily available global data sets. Evaluation of the VegET model ...

sustainable exploitation of land resources is directly affected by considering soil quality which finally will also conclude environmental protection. therefore, assessing different soil quality aspects which are sensitive to various land management practices seems too important. in this study, some selected soil quality indicators have been compared in five land use systems including untouched...

In order to assist in high-yield agricultural management multiple cropping systems, it is essential understand the link between rainy season onset and crops sowing dates, since considerably affects management, yield output. We built crop calendars derived from remote sensing products investigated dates of irrigated rainfed agriculture Western Bahia, a new important frontier Brazilian Cerrado. C...

alborz province with an area of about 5121.7 km2 has about 0.31% of the total area of the country. the total arable area of the province is about 48954 hectares. water, land and capital are the most important factors for agricultural production. by understanding the subjective beliefs, decision-making criteria and economic incentives of local farmers, the priority of crops can be achieved with ...

Subsurface soil water retention technology is a modern tool to increase the yield and improved saving. The goal of this paper review gathered three selected local experimental woks carried out in different regimes Iraq purposes improving productivity for strategy plants some vegetables crops irrigated by utilizing irrigation systems installing membrane trough. Moreover, retained rainfall was al...

The Thar Desert occupies about two-third part in the State of Rajasthan. Traditionally, agriculture in this region depends on the scanty rainfall. Irrigation was introduced in ths area by commissioning Indira Gandh Nahar Pariyojona (IGNP). The total irrigation potential is estimated as 13.87 lakh hectares. Canal irrigation has brought a significant change in the cropping pattern. The traditiona...

In cultivated landscapes, land use patterns related to the diversity of crops, their spatial arrangement into patches and succession over several years influence many biophysical processes production ecosystem services disservices. Understanding determinants these is a prerequisite for development acceptable alternative patterns. Most studies deem crop distribution at landscape level be result ...
