HarvestChoice is a research initiative, which generates information to help guide strategic investments in agriculture aimed at improving the well‐being of poor people in Sub-Saharan Africa

Phase I of HarvestChoice ran from October 2006 to June 2010, while Phase II began in December 2010 for a period of 4 years and a total budget of some $8.2M.

Purpose of the Initiative

Farming entails a great deal of risk and uncertainties. Weather varies, price fluctuates, soil degrades, pest damages, and, even climate changes. Farmers everywhere must cope with these uncertainties. Throughout the history of agriculture

Agriculture is the cultivation of animals, plants, fungi and other life forms for food, fiber, and other products used to sustain life. Agriculture was the key implement in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the...

Fertilizer is any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of plants. A recent assessment found that about 40 to 60% of crop yields are attributable to commercial fertilizer use...

Irrigation may be defined as the science of artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall...

, increase efficiency, and, increasingly, promote sustainability of the overall system.

With these techniques and tools in mind, each farmer must assess their local context and analyze the costs and benefits of adopting them, such as the additional labor and/or investment required. Careful and informed assessment is especially more important for farmers with limited resources, like smallholder farmers in developing countries. Even if farmers recognize that new approaches will likely improve production versus their traditional practices, they may still be highly risk averse for many legitimate reasons (e.g., lack of insurance markets, bad experiences in the past, or conceiving the inherently uncertain nature of farming).

Likewise, at a higher level, the national and international donors and policymakers share the farmers’ goal of improving food security cost-effectively. They, like farmers, must strategically assess the feasibility and profitability of available strategic and policy options and decide which ones to promote and where, with even greater deals of risks and uncertainties. If reliable estimates could be made of the current and potential patterns of crop productivity, many agricultural development investment and policy decisions would be significantly improved, or made with greater confidence.

HarvestChoice and its partners develop databases, tools, analyses, and syntheses designed to improve strategic investment and policy decisions. The overriding objective is to accelerate and enhance the performance of those crops and cropping systems most likely to bring significant benefits to the world's poor and undernourished.

to generate spatially‐specific knowledge is a cornerstone of the HarvestChoice initiative. A fundamental characteristic of agriculture (particularly subsistence agriculture) is the close coupling of its performance with prevailing biophysical conditions, conditions that can vary widely over space and time. HarvestChoice relies on its own and its partners' spatial datasets to provide new information on:
  • the location of the poor and undernourished in relation to major crop production systems
  • the dependence of both urban and rural poor on specific crops and crop products
  • the incidence and severity of major production constraints such as drought and disease in focus crops and locations
  • the potential benefits to the poor from alleviating such constraints
  • an inventory and characterization of existing and prospective technologies that might help address
  • an economic evaluation of the potential crop production, consumption, price, and trade, as well as the likely hunger and income consequences of a range of technology scenarios, and
  • the potential commercialization challenges that promising technology options might face.

Types of spatial data

There are five major, intertwined geographies of direct relevance to the work of HarvestChoice;
  • the spatial distribution and performance of agricultural production systems,
  • the spatial distribution and severity of production constraints (e.g., drought, low fertility soils, pests and diseases),
  • spatial variation in the potential efficacy of on‐farm interventions (e.g., improved seeds, mulching, supplemental irrigation, fertilizer use, biological control of pests),
  • spatial variation in access to input and output markets (e.g. time of travel to markets, farmgate prices of fertilizer and agricultural products),
  • spatial variation in national and local policies and regulations (that influence, for example, marketing decisions, the quality of infrastructure and services, the generation of and access to, and uptake of new technology).

Spatial products

HarvestChoice makes available spatially (and socio‐economically) explicit estimates of the potential welfare benefits of a range of interventions (e.g., on‐farm, market and market access, and national policy).

These maps (alongside tables, graphs, and text) provide information of direct relevance to agricultural development investors and policymakers. They do this by detailing the potential scale and distribution of economic benefits – including the identification of locations and social groups whose welfare might be impacted negatively. These outputs will, however, be supplemented by a larger collection of novel spatial data products that represent key, intermediate factors;
  • the baseline location and performance of agriculture worldwide (for at least 15 crops),
  • the incidence and severity of production constraints (for at least 30 abiotic and biotic constraints),
  • the potential response to on‐site technology and management interventions (e.g., for different crop varieties, different levels of nutrient, water, and pest management), and
  • the influence of changing transportation costs on profitability.


This amounts, potentially, to several thousand maps and associated datafiles.
