The Tonle Sap Basin, an expansive area of economic importance and the cultural heart of Cambodia, is being severely impacted by climate change, with increasing temperatures and shifting rainfall patterns having a major impact on water resources and agricultural productivity, as well as increasing the frequency and intensity of extreme events such as drought and floods.

The impacts of climate change are exacerbated by the degradation of forest ecosystems, threatening the regulation of hydrological cycles in the region. As the agroecological landscape is degraded, the critical ecosystem services they provide are being lost, with severe consequences for the sustainability of water resources and the livelihoods they support, as well as the tourism industry, which is a major contributor to the local and national economy.

The resultant impacts on natural resource-based livelihoods are driving local communities to adopt maladaptive practices such as agricultural expansion into forest areas, fuelling a negative cycle of degradation in the catchments.

To address climate vulnerability and the drivers of environmental degradation in the Tonle Sap Basin and safeguard the natural and cultural heritage of the region, the Government of Cambodia will introduce a systematic and integrated approach to landscape management.

This will be implemented through two complementary projects – one positioned under the GEF-8 Integrated Programme for Ecosystem Restoration focusing on the conservation and restoration of forest ecosystems across the Tonle Sap Basin, and this proposed five-year project focusing on building the resilience of communities within the Tonle Sap Basin against the increasing impact of floods and drought.

Introduction

The Tonle Sap Basin, an expansive area of economic importance and the cultural heart of Cambodia, is being severely impacted by climate change, with increasing temperatures and shifting rainfall patterns having a major impact on water resources and agricultural productivity, as well as increasing the frequency and intensity of extreme events such as drought and floods.

The impacts of climate change are exacerbated by the degradation of forest ecosystems, threatening the regulation of hydrological cycles in the region. As the agroecological landscape is degraded, the critical ecosystem services they provide are being lost, with severe consequences for the sustainability of water resources and the livelihoods they support, as well as the tourism industry, which is a major contributor to the local and national economy.

The resultant impacts on natural resource-based livelihoods are driving local communities to adopt maladaptive practices such as agricultural expansion into forest areas, fuelling a negative cycle of degradation in the catchments.

To address climate vulnerability and the drivers of environmental degradation in the Tonle Sap Basin and safeguard the natural and cultural heritage of the region, the Government of Cambodia will introduce a systematic and integrated approach to landscape management.

This will be implemented through two complementary projects – one positioned under the GEF-8 Integrated Programme for Ecosystem Restoration focusing on the conservation and restoration of forest ecosystems across the Tonle Sap Basin, and this proposed five-year project focusing on building the resilience of communities within the Tonle Sap Basin against the increasing impact of floods and drought.

The proposed landscape and watershed management solutions will take a systems-based approach, accounting for three key pillars identified for sustainable investment in Cambodia, namely governance, finance, and people. When underpinned by a foundation of research, knowledge and learning, an approach built on these pillars will ensure that the appropriate enabling environment is created for sustainable and scalable impact, with crosscutting benefits.

Improved management of vulnerable landscapes and watersheds across the Tonle Sap Basin will include the conservation and active rehabilitation of degraded ecosystems to restore the provision of critical ecosystem services, supported by innovative finance mechanisms that will facilitate the long-term maintenance and scaling of the approach. This will also involve working with local communities to address the drivers of degradation while maintaining livelihoods and culture.

Against this background, the proposed five-year project, to be implemented by Cambodia’s Ministry of Environment, will build climate resilience while simultaneously disrupting the key drivers of land degradation to contribute to national efforts to restore watershed ecosystems and their services in the Tonle Sap Basin, with specific focus on Siem Reap province and the Phnom Kulen landscape. Moreover, the project will support sustainable livelihoods, thereby contributing to the country’s green growth.
