Food security: Close crop yield gap

Climate change impacts on crop yield, crop water productivity and food security – A review

This paper provides a comprehensive review of literature related to the assessment of climate change impacts on crop productivity using climate, water and crop yield models. The existing studies present that climate change models with higher spatial resolution can be a way forward for future climate projections. Meanwhile, stochastic projections of more than one climate model are necessary for ...

Household Food Security: Case of Summer Crop Growers in Shoushtar Township, Iran

associated with this condition among summer crop growers in Shoushtar Township, Khouzestan Province, Iran. This cross-sectional survey study was conducted from September 2015 to February 2017. The population consisted of summer crop farmers in the Shoushtar Township (N=850). The sample size was determined based on Morgan table (n=150). For analyzing food security level, the 18-item USDA househo...

Integrated soil-crop system management for food security.

China and other rapidly developing economies face the dual challenge of substantially increasing yields of cereal grains while at the same time reducing the very substantial environmental impacts of intensive agriculture. We used a model-driven integrated soil-crop system management approach to develop a maize production system that achieved mean maize yields of 13.0 t ha(-1) on 66 on-farm expe...
