Climate change research, capacity building and communication on climate extremes over South Asia

Climate change is a global issue that significantly impacts various regions, including South Asia, which is particularly vulnerable to climate extremes. Extensive research is required to address the complex interplay between climate change and extreme weather events in South Asia (Bangladesh, Nepal and Pakistan). This study presents a case study of an Asia-Pacific Network for...

Plausible alternative future of mangroves and their ecosystem services: Case studies from Asia-Pacific region

Over the past few decades, scenario analysis emerged as a useful tool for environmental decision-making amidst multiple uncertainties. Using the influential drivers of change, scenarios portray the range of plausible alternative futures useful for quantifying the synergies and trade-offs of vital ecosystem services across multiple development trajectories. In this research, we demonstrate two case examples...

Towards sustainable mangrove-shrimp aquaculture through capacity building and partnership in the Mekong River Delta

Vietnam, the world's third-largest shrimp producer, witnessed a surge in shrimp farming when rice fields were converted into ponds, aiming to alleviate poverty in the Mekong River Delta (MRD). However, this growth significantly contributed to the decline of mangrove forests, as indicated by empirical and geospatial data. Local authorities have encouraged the application of “International...

Equipping local self governments and development practitioners in managing common pool resources – A case of Pampa River in Kerala State, India

Governments face challenges and constraints in managing Common Pool Resources (CPRs) worldwide. Almost all developing countries have begun to implement decentralised policies and decision-making systems for delivering public services and the management of environmental goods. In any government structure, distributing public goods is difficult as it will be challenging to exclude potential beneficiaries from obtaining...

Impact of climate change, climate variability and adaptation in the coastal area of Cambodia

Cambodia’s coastal zones are highly dependent on climate and weather, making them susceptible to climate change and causing farmers’ livelihoods to be more vulnerable compared to urban residents. Since climate issues already impact the agricultural sector in Cambodia, this paper aims to assess the impact of disasters in the context of climate change, which impacts...

A case study on regional arsenic sources and its distribution in Mekong River groundwater

Arsenic contamination in the Mekong River is a well-known environmental issue yet to be resolved due to its transboundary nature which further limits its access and data collection. Other than that, the key mechanisms that controlling the arsenic release in Mekong sub-region groundwater was heterogeneously distributed and can be varied from region to region. The...

Future changes in mean and extreme precipitation over Peninsular Malaysia using CORDEX-SEA 5 km simulations

The Coordinated Regional Climate Downscaling Experiment (CORDEX) Southeast Asia further downscaled three of its 25 km products, i.e. EC-Earth, HadGEM2-ES and MPI-ESM-MR forced regional climate simulations to a higher resolution of 5 km. A newer RegCM4.7 model was used for this exercise. For the simulations over Peninsular Malaysia, analysis shows that these simulations have much...

Climate-smart agriculture strategies for South Asia to address the challenges of climate change: Identification of climate-resilient agriculture practices for India, Bangladesh, and Afghanistan

In South Asia, agriculture is pivotal for food and nutritional security and the livelihood of more than 50% of the population. Food production and nutritional security pressures intensify as urbanisation decreases the agricultural land area amid population growth. Climate change complicates this scenario by introducing elevated temperatures, extreme climatic events, surging sea levels, and increased...

Climate change impacts on spatiotemporal variation of extreme weather and its consequences on dam optimisation and risk management in the Cagayan basin, Philippines

Extreme weather threatens livelihood and urban development in the Philippines. However, addressing their effects and occurrences is a significant challenge, particularly in the Cagayan River Basin (CRB), due to increasing population and the dilemma of dam operations for floods and droughts management. Therefore, this paper focuses on investigating the impact of climate change on extreme...
