This paper provides a comprehensive review of agricultural policy and public agricultural expenditure (PAE) in China. China shifted away from taxing agriculture to supporting agriculture in the mid-2000s, but the sector faces mounting demographic, biophysical, and trade challenges. PAE in China...

The great diversity of agricultural activities and practices across the African continent has significant implications for technology transfer and productivity growth. This paper compiles diverse spatial data on biophysical conditions, farming systems, demographics, and infrastructure to...

Purpose: The purpose of this paper is to estimate shadow prices of agricultural carbon emissions produced by agricultural inputs, rice paddy and burning crop residue, and to explore the impact of cropping pattern on marginal abatement cost (MAC). Design/methodology/approach: The shadow price of...

Purpose: The purpose of this paper is to examine the status of the supply reliability of groundwater irrigation, and discuss how it is affected by climate change and tubewell density in rural China. Design/methodology/approach: This study is based on a nine-province village survey and secondary...

Coffee is the most important export crop in Uganda and an important source of income for smallholder farmers in large parts of the country. The paper first investigates the challenges and opportunities faced by the Ugandan coffee industry, especially the decline in the world coffee market,...

The concentration of crop cultivation can be measured in terms of spatial clustering and of inequality in the distribution of the cropland area. We used official agricultural statistics at the county level (N = 2,354) for each year from 1980 to 2011 for all of China to analyse the changes in...

Purpose: Drought-related climate risk and access to credit are among the major risks to agricultural productivity for smallholder farmers in Kenya. Farmers are usually credit-constrained due to either involuntary quantity rationing or voluntary risk rationing. By exploiting randomized...

Spatially explicit global cropping system data products, which provide critical information on harvested areas, crop yields, and other management variables, are imperative to tackle current grand challenges such as global food security and climate change. These cropping system datasets are also...

Extreme events, such as those caused by climate change, economic or geopolitical shocks, and pest or dis- ease epidemics, threaten global food security. The complexity of causation, as well as the myriad ways that an event, or a sequence of events, creates cascading and systemic impacts, poses...
