There are important public needs to be addressed within the Asian region, such as degraded environments and their impact on health and the land productivity needed to support the population. Hundreds of millions of people in the region are chronically malnourished or suffer from the lack of reliable sources of clean water. While food production can be boosted by new farm technologies raising cr...
most developing countries have achieved productivity growth in economic sectors like agriculture for more than 30 years. universities and governmental research centers have tried to generate knowledge with direct social and economic effects during these decades. so, productivity and production growth can be attributed to technological changes made possible through investment in agricultural res...
Should agricultural development programmes target women in order to increase productivity? This article analyzes the challenges in distinguishing women's agricultural productivity from that of men. Most of the literature compares productivity on plots managed by women with those managed by men, ignoring the majority of agricultural households in which men and women are both involved in manageme...
This paper estimates the role of agronomic inputs in cereal yield improvements and the consequences for countries' processes of structural change. The results suggest a clear role for fertilizer, modern seeds and water in boosting yields. We then test for respective empirical links between agricultural yields and economic growth, labor share in agriculture and non-agricultural value added per w...
Declining agricultural productivity has been a challenge worldwide and especially in Sub-Saharan Africa (SSA). Low attributed to factors such as poor farm management practices, soil moisture stress, infertility, degradation, among others. The nations the SSA are prone insufficient crop yields due their inadequate capacity adapt good practices that support integrated fertility water (ISFWM) prac...
Growth of total factor productivity has contributed 41 per cent of output growth in Indonesian agriculture since 1975. This study examines the extent to which publicly funded agricultural research within Indonesia has contributed to this productivity growth, while allowing for other possible determinants, including spillovers from international agricultural research, extension, weather changes,...
Monitoring of net primary productivity (NPP) is especially important for the fragile ecosystems in arid and semi-arid regions. Great interest exists in observing large-scale vegetation dynamics and understanding spatial and temporal patterns of NPP in these areas. In this study we present results of NPP obtained with the model BETHY/DLR for Kazakhstan for 2003-2011 and its spatial and temporal ...
