By all accounts we will run out of food in the not-so-distant future at our current rate of global food production. New maps help visualize where we can increase food production by capturing the share of cropland around the globe.

How does a potentially devastating disturbance, such as drought or excess rainfall, effect the ripples of trade flow in sub-Saharan Africa? What is the spatial relationship between biophysical characteristics and net exports in a particular country or region? What do historical patterns and spatial variability in the environment, agricultural production, and natural shocks tell us about food distribution and possible mitigation through responsive trade flows? HarvestChoice explores these questions in a recently published chapter included in the flagship publication, ReSAKSS Annual Trends and Outlook Report (ATOR) 2013.

HarvestChoice is interested in developing global indices that capture the level of sustainable intensification in agricultural systems. We are exploring the utility of Net Primary Productivity (NPP) as a co-indicator of environmental impact and ecosystem services. This post describes the rationale and some of our findings from a pilot study recently completed by our team.

Maps describing Earth's land cover tell different stories. Which should we believe?

If there is one consensus in agriculture development it is the idea that crops will need to produce more from existing agricultural land in the coming decades. In other words, agriculture will need to be intensified.

Jason Beddow of HarvestChoice and the University of Minnesota, along with Darren Kriticos of CSIRO, explain how HarvestChoice is revolutionizing the science of tracking -- and predicting -- the paths of devastating crop pests and diseases such as UG99.

Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and HarvestChoice are now working together to apply innovative, “bio-economic” approaches to improve the food security of poor people in sub-Saharan Africa and South Asia. Together, our organizations will merge biological, environmental and economic tools to track global food pests and better target strategic investments to improve global food security.

SPAM2000 (any version) is based on a large set of data which centers as much as possible on the year 2000: land cover / land use (Boston University’s MODIS-derived land cover 2000 and JRC’s GLC2000), crop suitability (Global AEZ Zones 2000 by FAO and IIASA), irrigated areas (FAO and CESR of University of Kassel), population density (CIESIN), and, most importantly, national and sub-national crops statistics for 2000.

Many of HarvestChoice spatial datasets are organized and released on 10-km grids. To make spatial analyses easier for researchers (even without having access to GIS platform), we put data layers from multiple themes together in one denormalized big table. This post describes the methodology and presents a prototype.
