Use of participatory epidemiology for impact assessment

Participatory methods can be used for impact assessment of animal health projects. For example:

The system boundary - what are the spatial boundaries of the project under assessment? Participatory mapping can be used to define the boundaries, and the communities, livestock and resources within the boundary. Maps can also show transient movements into or out of the project area.

Local impact indicators - how do local people define impact? Informal interviews can be used to understand local perceptions of benefits derived from health livestock.

Changes during the project - how did livestock-derived benefits change during the project, if at all? Scoring tools or proportional piling can show changes over time. These methods can also be used to look specifically at perceptions of changing disease incidence and mortality patterns.

Animal health service providers - how do people compare different types of animal health service provider? Matrix scoring can be used to compare different types of providers against indicators such as accessibility, availability, affordability and so on.

Attribution - were the changes which occurred during a project attributable to project inputs, or something else? Simple ranking methods can be used to explore attribution issues.
