Proximity to markets - determined in part by road and rail investments -enhances both the profitability of self-employment and opportunities for non-agricultural wage labour. One problem in assessing the correlation of access to infrastructure with household activities and income is that there are varying definitions of “access” related to differences in measuring “infrastructure,” such as roads, travel time, electricity, piped water, and so on. Some general advice has been that countries should use social policies to protect incomes in the short term and provide support for farmers who are unable to adjust, while correcting market failures and investing in public goods in order to strengthen agricultural incomes (OECD, 2012a).
