Climate change has direct and indirect consequences on crop production and food security. Agriculture and cropproduction is one of the factors which depend on the weather conditions and it provides the human requirements inmany aspects. The objective of this study is to assess the impacts of future climatic change on irrigated rice yieldusing the CERES-Rice model in the Southern Coast of Caspia...

Through the website of International Water Management Institute, the referenced evapotranspiration (ET0) was found which was calculated by the meteorological data during 1961-1999 from 147 stations in Sichuan Province. Further, according to the crop coefficients of rice, maize, wheat, rape, the water requirements (ET) of main crops were estimated by using Food and Agriculture Organization (FAO)...

We assess farmers' incentives and the conditioning factors for adoption of agricultural technologies under climate risk and evaluate its impact on food security in Niger. Results show that while the use of modern inputs and organic fertilizers improves productivity, results are unclear for crop residues. Results also show that factors driving modern input use are different than those of crop re...

Conservation agriculture (CA) integrates ecological management with scientific agricultural production. CA promotes minimal disturbance of the soil by tillage (zero tillage), balanced application of chemical inputs (only as required for improved soil quality and healthy crop and animal production), and careful management of residues and wastes. CA Promotes application of fertilizers, pesticides...

In this paper, we present the results of our study on the operational application of the reflectance-based crop coefficient for assessing table grape irrigation requirements. The methodology was applied to provide irrigation advice and to assess the irrigation performance. The net irrigation water requirements (NIWR) simulated using the reflectance-based basal crop coefficient were provided to ...

The water demand to meet seasonal and long-term water needs in Thessaly, central Greece, is related to historical semi-arid conditions in the region, which is the main agricultural area of the country. In this paper irrigation water requirements are assessed through the estimation and monitoring of crop evapotranspiration ETc for cotton fields in Thessaly. Remotely sensed data are used to delin...
