Vulnerable Deltas in Southeast Asia: Climate Change, Water Pollution, and Socio-Economic Transformation

share

East-West Center researchers, with support from the Henry Luce Foundation, recently launched a project to address the multidimensional vulnerabilities facing three major deltas in Southeast Asia. These include the Chao Phraya Delta in Bangkok to Suphan Buri, Thailand; the Mekong Delta in An Giang Province, Vietnam to Phnom Penh, Cambodia; and the Mahakam Delta in East Kalimantan, Indonesia. In collaboration with the Wilson Center’s China Environment Forum (CEF), Chulalongkorn, Srinakharinwirot, Khon Kaen, Gadjah Mada, An Giang Universities, the Asian Vision Institute, and other local partners in Southeast Asia we will expand and deepen existing research networks to explore climate, environmental, social and infrastructure threats to deltas.

Southeast Asia (SEA) is culturally and ecologically defined by its relation to water, and its fluctuating scarcity and overabundance, especially in delta environments. In this interdisciplinary, multi-sited research and multimedia education initiative, we will investigate the inter-related socio-economic vulnerabilities and environmental degradation occurring across resource sectors from climate change and rapid development in the three deltas. Focusing on deltas allows us to link upstream processes of land use and riverine changes with the dynamics of increasing infrastructural connectivity and conflict, and flows of water, waste, labor, and human migration. Deltas are productive not only biologically but also economically, where the seasonal deposit of sediment in these saturated terrains have given rise to dynamic sociocultural and material wealth. Delta environments, especially those in SEA, are at the center of urban expansion driven by economic growth and infrastructure development, and yet are listed as some of the world’s most vulnerable cities and ecological habitats due to the impacts of climate change.

SEA cities are embedded in delta geographies and must be understood as integral to far-flung rural farming landscapes, forested watersheds, and riverine habitats, which have been undergoing rapid land-use-and-land-cover change. The agricultural productivity and ecological integrity of SEA deltas are increasingly threatened by the combined effects of natural and human-induced changes, including upstream hydropower development, irrigation and urban development, regional infrastructural linkages, waste pollution, and slow-onset environmental change. Disruptions to the hydrology and sediment flow at the transboundary level alongside local land-use changes have many consequences for delta environments and inhabitants who are already encountering increasing riverbank erosion, land subsidence, and salinization. The projected effects of climate change and weak domestic and transboundary land and water governance are expected to worsen these issues, with critical implications for food security, farming livelihoods, and rural-to-urban migration in this region.

EWC and CEF will collaborate with our in-country SEA partners to study the multidimensional vulnerabilities and socio-ecological transformations of SEA deltas. Despite the well-documented vulnerabilities to climate change “where land meets water”, delta cities continue to be inundated with major physical infrastructure networks, waste pollution, economic development packages, and rural-to-urban in-migration. Our multidisciplinary team of academics and practitioner, stitches together a bottom-up effort that stretches across the three deltas in mainland and insular SEA. We will engage in capacity-building learning activities, build co-teaching modules and multimedia outreach capacities for producing applied knowledge on the sociocultural and biophysical transformations needed to protect these deltas. We will also build bridges between China and SEA by focusing on China’s direct investment into the region and its social environmental impacts on delta environments, including plastic waste.
