HarvestChoice data release r2.5

HarvestChoice releases over 500 newly-updated indicators for Africa South of the Sahara at 10 km resolution.

This week HarvestChoice launched over 500 newly-updated indicators in its catalog of 5-arc-minute geospatial layers for sub-Saharan Africa. Underlying each indicator, such as health and poverty variables, agricultural production and area, climate and soil, and access to market, are recent sub-national data sources and improved methodologies.

With now over 750 harmonized data layers, HarvestChoice is hub to the largest and most diverse geospatial database for Africa South of the Sahara. All indicators are openly available for download from this website in a variety of formats (tabular CSV, ESRI ASCII, and GeoTIFF rasters).

Included in this week's release r2.5 are:

  • SPAM 2005 v2.0 commodity indicators: harvested area, production, yield, and value of production for over 50 commodity groups
  • maize yield variability under low/high input systems (simulated)
  • mean, min, max, and probability of cropland area sourced from IIASA
  • 50-year average and variation in rainfall sourced from CRU 3.22
  • LandScan 2012 population count and density
  • IUCN/WDPA 2014 protected areas (7 definitions)
  • soil fertility (soil organic carbon content) sourced from ISRIC/AfSIS
  • bovine grazing and stover production (2000) sourced from ILRI

Data Access

All HarvestChoice data layers are provided in raw format at 10 km resolution (5-arc-minute). Users may decide to further aggregate and summarize indicators across administrative boundaries or other geographic domains (agro-ecological zones, for example) for subsequent analyses. HarvestChoice produces tools to help users visualize and tabulate raw data to tell their stories of where.

Download raw indicators from HarvestChoice data catalog

The Data & Maps section on this website references all available indicators. You may also use the site-wide search to easily locate specific layers.


Visualize indicators in Mappr

Mappr allows you to overlay, export, and visualize indicators and analyse the spatial relationships between indicators. You may also interrogate maps using point/polygon summaries, domain summaries, and other analytical features from the toolbox on the right.


Summarize indicators using Tablr

In addition to summary features available in Mappr Tablr also quickly tabulates statistics. Just select indicators from the left menu, and select row and column dimensions to aggregate.

Conduct advanced analyses using HarvestChoice Data API

Other analytical tools (e.g. ranking and spatial targeting methods) are available using HarvestChoice Data Services (RESTful API). This is suitable for programmatic use, and more documentation may be found on GitHub.


In the Pipeline

What other data layers make the grade? HarvestChoice is planning an expanded list of gender-disaggregrated health and nutrition indicators derived from a large set of Demographic and Health Surveys (DHS) for Africa, and a major update to HarvestChoice time-to-market layers (including revised road network and land cover).
