Abstract Major environmental indicators require data at a spatial resolution below administrative units as found in economic models. The CAPRI-Dynaspat project added spatial results for ...

This study has estimated the total factor productivity (TFP) and its share in output growth, and returns to public investments on research in agriculture in India. The contribution of agricultural research in reducing real cost of production and attainment of food self-sufficiency has also been estimated for the country. The estimates of TFP have shown considerable variations across crops in di...

In recent years, agricultural growth in China has accelerated remarkably, but most of this growth has been driven by increased yield per unit area rather than by expansion of the cultivated area. Looking towards 2030, to meet the demand for grain and to feed a growing population on the available arable land, it is suggested that annual crop production should be increased to around 580 Mt and th...

Agricultural risks constitute a fundamental challenge in Nigeria, hence the importance of agricultural insurance in managing farm risks cannot be underestimated. As the crop sub-sector contributes about 85% of the agricultural GDP in Nigeria, this study focussed on awareness and factors that can enhance the adoption of crop insurance among crop farmers in Nigeria. Data collected from 310 random...

There is a growing concern that climate changes will lead to significant impact to agriculture, thus having a global effect in food production. The application of crop models to study the potential impact of climate change and climate variability provides a direct link between models, science and the concerns of the society. The objective of this work is to demonstrate an information architectu...

Biotic stress and diseases caused by pathogen attack pose threats in crop production and significantly reduce crop yields. Enhancing immunity against pathogens is therefore of outstanding importance in crop breeding. However, this must be balanced, as immune activation inhibits plant growth. This immunity-coupled growth trade-off does not support resistance but is postulated to reflect the real...

Global agricultural and food systems face the challenge of feeding a growing world population in the face of finite and diminishing resources. To guide the redesign of agricultural systems, farmers and policymakers are increasingly turning to agroecology. Organic agriculture has historically integrated agroecological practices within its regulatory framework; however, questions remain as to the...
