Flood dynamics in the Vietnamese Mekong Delta from Earth observations

This study analysed flood dynamics in the Vietnamese Mekong Delta (VMD) from 2001 to 2023, using Terra MODIS MOD09A1 remotely sensed imagery data on the Google Earth Engine platform. The workflow includes data collection, preprocessing, flood extraction, and analysis of flood dynamics. We used the R programming language to analyse flood extent, duration, distribution, and...

Assessing urban heat islands in Southeast Asia megacities: An integrated study of land use, climate change and heatwave occurrences

Rapid urbanisation and climate change are intensifying Urban Heat Island (UHI) effects across Southeast Asian (SEA) megacities, compounding heatwave risks and threatening urban sustainability. This study, conducted under the Asia-Pacific Network for Global Change Research (APN) collaboration, presents the first integrated, multi-decadal assessment of UHI–heatwave interactions in SEA, focusing on Kuala Lumpur as a representative...

Integrating geospatial technologies in climate-smart agriculture planning and management: A review focused on South Asia

Climate change poses a significant challenge to global food security and agricultural sustainability, making innovative solutions essential. Integrating geospatial technologies into agricultural planning and management provides better opportunities to advance Climate-Smart Agriculture (CSA). This review examines the role of geospatial technologies, such as Geographic Information Systems (GIS), Remote Sensing (RS), and Global Navigation Satellite System...

A hierarchical and inclusive zonation of Sundarbans for monitoring and management of the world heritage area

The Sundarbans is the world’s largest mangrove forest, spanning across India and Bangladesh. Several studies have been conducted on various aspects of the ecosystem, primarily at a local scale, with most broad-scale studies confined to either the Indian or Bangladeshi part. To enhance the conservation and management of this extensive mangrove ecosystem, comprehensive studies encompassing...

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...

Spatial variability of nutrient sources determining phytoplankton Chlorophyll-a concentrations in the Bay of Bengal

Primary production is a key marine ecosystem driver in the Bay of Bengal and is important for the societies and economies of the surrounding countries. Although the availability of inorganic nutrients is known to control primary production in this region, the specific nutrient sources that affect primary production in different parts of the bay have...
