Cambodia is one of the poorest countries in the world; much of its population live in rural areas and many live below the local poverty line. The management of common property aquatic resources is of over-riding importance to food security and sustainable rural development in Cambodia. The key groups of poor people who use aquatic resources as part of their diverse livelihoods portfolios are subsistence fishers, small-scale aquaculture practitioners and aquatic resources collectors.
