This working paper has been prepared jointly for the Intergovernmental Authority on Development Livestock Policy Initiative (IGAD LPI) and the Pro-Poor Livestock Policy Initiative (PPLPI).
The work described in this paper contributes towards making available standardised spatial data to help analyse policy options, to target policy interventions and to evaluate their impact – contributing to the evidence base underpinning pro-poor livestock policies.
It examines the relationships between poverty and accessibility for some 5,500 rural households in Uganda, by exploring the relationships between welfare, measured in terms of household expenditure and poverty head count, and a) measures of physical distance and travel time to markets and roads, and b) different measures of the potential for interaction, estimated in terms of population density and indices of proximity.
Results show that distance and travel time to roads are not highly correlated with welfare, while distance and travel time to population centres are highly correlated with wealth indices: welfare decreases rapidly as access to population centres gets worse. It appears that access to intermediately sized centres of population is relatively more important than is access to very small, local markets, or to much larger population centres.
Expenditure and poverty head count are also strongly correlated with population density and with indices of proximity: people are far better off when there is a high potential for interaction with other people. Whilst the directions of causality are difficult to demonstrate, this analysis reveals the nature of these correlations and the important predictive power of accessibility measures in poverty mapping.
