The June 2012 issue of Insights, IFPRI’s quarterly magazine, talks up HarvestChoice’s increasingly popular online tool: MAPPR. So friendly to use that a writer and a graphics designer combined wits to create the MAPPR-generated visuals for the article.
Risk: we all know what that means, right? But why is it such a critical part of our HarvestChoice portfolio, what does it mean when you look through the lens of farming in Sub-Saharan Africa?
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.
We're not normally focused on this part of the world, but something like the Japanese tsunami tends to divert your attention.
HarvestChoice uses a so-called
meso-scale spatial grid typically at 10km or 5-arc minute resolution.
How to use the weather generator in the DSSAT Crop Systems Model for climate change studies, and what should I know? Good question.
Long-term yield trials are great resources for agricultural researches in multiple disciplines, but such dataset have not been readily available in Sub-Saharan Africa. The Hatfield Experimental Farm in Pretoria, South Africa, is an exceptional case that has been providing maize yield and fertilizer trial dataset with 32 treatments since 1939. In collaboration with University of Pretoria, HarvestChoice facilitated the re-discovery of raw yield dataset from the trial to study the measured long-term yield variability.
For crop modeling researchers who are in need of finding soil profiles at regional-scale in Sub-Saharan Africa (SSA), this post gives a spatial dataset that delineates SSA into 588 units and corresponding soil profiles, based on the WISE v1.1 and HC27 soil profile databases.
