- Around 1.3 billion tonnes of waste are generated globally each year, with projections showing a 70% increase in waste by 2050 due to urbanization and population growth; Malaysia alone generates about 38,200 tonnes of waste daily, threatening its sanitary landfills' longevity.
- In Batu Pahat, Malaysia, which has a population of 495,000 and lacks an operational sanitary landfill, a study identified suitable sites for landfill development using the Analytical Hierarchy Process (AHP), resulting in six proposed sites deemed very suitable for such activities.
- The identified sites are strategically located more than 2000 meters from rivers, over 3000 meters from fault zones, and over 1000 meters from flood-pr
Climate change and soil erosion are very associated with environmental defiance which affects the life sustainability of humans. However, the potency effects of both events in tropical regions are arduous to be estimated due to atmospheric conditions and unsustainable land use management. Therefore, several models can be used to predict the impacts of distinct climate scenarios on human and environmental relationships.

However, during the restriction period due to the COVID-19 outbreak, anthropogenic activities have been suspended, which clearly shows a good opportunity for a better environment. Therefore, we aimed to analyze the variation of AMD-associated water pollution in three main zones of the Chini Lake catchment area using Sentinel-2 data for the periods pre-movement control order (MCO), during MCO, and post-MCO from 2019 to 2021.

This research was carried out to investigate the accumulated levels of metal ions and radionuclides in water, soil and plants following phosphogypsum organic (PG organic) added to a sandy soil for 23-month in 3 cropping seasons.

- The study examines the spatial distribution and spread of COVID-19 during the first and second waves in South Sumatra, Indonesia, using GIS software for mapping.
- The research found that the highest infection rates were in densely populated areas like the Palembang district, while remote areas saw lower rates; the epidemic spread rapidly from August to December 2020.
- Key meteorological factors like air temperature, wind speed, and precipitation were significantly linked to higher spread rates in the second wave, providing insights for future control and prevention strategies.
