A comparison between biodiversity monitoring systems to improve natural resource management in Tonle Sap Biosphere Reserve, Cambodia

The choice between professional and community-based methods for monitoring biodiversity and biological resources is
largely dependent on the availability of resources. Professional methods are more expensive than community-based methods
and are often not feasible in developing countries where technical and financial resources are limited. There is, therefore,
a need to assess already existing or develop new simple, cost-effective approaches to monitor biodiversity and biological
resources in developing countries. This paper examines and compares three systems for monitoring biodiversity and biological
resources in Tonle Sap Great Lake of Cambodia: (1) state-managed monitoring, (2) NGO-managed monitoring and
(3) community-based monitoring. Data were generated using key informant interviews, focus group discussions and direct
observation. The three types of monitoring are assessed with respect to perceived cost, methodological rigour, ease of use,
compatibility with existing day-to-day activities of the local stakeholders and efficiency of intervention. Recommendations
are made on how to improve each individual type of monitoring as well as the overall quality of monitoring on Tonle Sap
Lake.
