Prices are one of the main components of household wellbeing due to their effect on real incomes and expenditures. High food prices most impact the poorest strata of the population who spend the greatest share of their income on food, and affect food buyers disproportionately more than food sellers. In 2007-8 and 2011 widespread food price crises, with soaring food prices, triggered world-wide concern about threats to global food security, questioning the complacency created by many years of low commodity prices. HarvestChoice is equally concerned with spatial patterns of input and output prices since high transport and market transactions costs are a significant barrier to the adoption of many types of innovations and smallholder participation in markets. HarvestChoice draws on multiple data sources for compiling prices, ranging from official FAO-UN statistics to specialized CG centers, household survey data and, where they exist, market information systems.
