“…Drawing on Commodore and colleagues ( 2017 ), we characterize bottom-up community-based environmental-monitoring programs as initiated, implemented, and managed by the communities. Top-down programs are typically designed by outsiders to address perceived community needs (Danielsen et al 2009 , Seak et al 2012 ). We also noted whether CBM activities incorporated Indigenous or local knowledge.…”

Effective responses to rapid environmental change rely on observations to inform planning and decision-making. Reviewing literature from 124 programs across the globe and analyzing survey data for 30 Arctic community-based monitoring programs, we compare top-down, large-scale program driven approaches with bottom-up approaches initiated and steered at the community level. Connecting these two approaches and linking to Indigenous and local knowledge yields benefits including improved information products and enhanced observing program efficiency and sustainability. We identify core principles central to such improved links: matching observing program aims, scales, and ability to act on information; matching observing program and community priorities; fostering compatibility in observing methodology and data management; respect of Indigenous intellectual property rights and the implementation of free, prior, and informed consent; creating sufficient organizational support structures; and ensuring sustained community members’ commitment. Interventions to overcome challenges in adhering to these principles are discussed.

“…Due to this natural phenomenon, Tonle Sap Lake is of great significance to flood control, economic development, and the ecological value of Cambodia. At present, the researches of Tonle Sap Lake mainly focus on biodiversity [25][26][27], water quality [28][29][30], hydrological characteristics [31][32][33], social and economic conditions [34,35].…”

Lake surface water temperature (LSWT) has a significant impact on aquatic ecosystem. This study aimed to reveal the variations and driving factors of LSWT in Tonle Sap Lake, the largest freshwater lake in South Asia. For this purpose, the datasets of LSWT-day, atmospheric temperature (AT), lake surface area (LSA), watershed land use and cover change (WLUCC) were extracted based on MODIS products and AT images by remote sensing technology. Then, through GIS geospatial analysis technology and mathematical statistical methods, the spatial-temporal variations of LSWT-day, AT, LSA and WLUCC were analyzed, and the relationships between LSWT-day and AT, LSA, WLUCC were further discussed. Results showed that: 1) from 2001 to 2018, the annual mean LSWT-day and AT showed a significant warming trend. AT was a main driving factor affecting LSWT in Tonle Sap Lake.2) LSA showed a slightly decreasing tendency and had an obvious negative correlation with LSWT-day, which was an important factor affecting LSWT. 3) WLUCC had undergone drastic changes and its influence on LSWT could not be ignored. In summary, this paper fills the gap of the long-term series of LSWT research in Tonle Sap Lake and enhances the understanding of LSWT changing mechanism for similar lakes.

“…The primary objective of this paper is to assess the three existing monitoring systems from the perspective of methodology rigour, perceived cost, user-friendliness, compatibility with existing day-to-day activities of the local stakeholders, efficiency of intervention and constraints and opportunities for execution. The paper, moreover, provides the basic framework for an in-depth discussion of locally based monitoring methods (see Seak et al 2011).…”

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-today 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.
