Capacity development training workshop on crop simulation modelling and effects of climate risks on agricultural production systems in Southeast Asia

Southeast Asia (SEA) has experienced frequent floods and droughts, posing severe challenges for farmers, agricultural scientists and extension officers. Consequently, crop modelling has become imperative in developing agricultural production systems and making informed decisions at the field level. The Decision Support System for Agrotechnology Transfer (DSSAT) can be effectively utilised at both farm and regional...

Artificial recharge initiatives in India: Challenges and future scope

Artificial recharge of aquifers is regarded as a fundamental supply-side strategy in India to address the prevalent issue of groundwater over-exploitation. Rainwater harvesting and artificial recharge are often implemented as cohesive sets of interventions because of the significant collateral benefits of rainwater harvesting. Central and state governments have implemented various schemes that incorporate rainwater harvesting...

Impact of Water Management on Methane and Nitrous Oxide Emission Dynamics in Asian Paddy Ecosystems

With increasing demand for rice productivity linked with intense pressure on water availability in Asia, novel strategies are sought to optimise water management in paddy cultivation without compromising the yield. The conventional submerged paddy ecosystems not only consume water excessively but also constitute a major source of methane (CH4) and nitrous oxide (N2O), two highly...

Assessment on the impact of mining and industrial activities in groundwater quality in Chandrapur, Maharashtra through remote sensing and GIS applications

This study evaluated the quality of groundwater in Chandrapur Taluka, Maharashtra, using geospatial techniques and data from 2014 and 2018. The study assessed various water quality parameters such as chloride, fluoride, pH, residual sodium carbonate (RSC) and sodium adsorption ratio (SAR). The findings showed that chloride concentrations were mostly within acceptable limits, but there was...

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...
