Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Synergistic Effects of Salinization and Artificial Root Exudates on Soil Phosphatase Activity in Coastal Soil

Land Degradation &Development, EarlyView.
ABSTRACT Coastal soil salinization from rising seawater levels has adverse impacts on soil function, seed germination, and plant growth. Root exudates play a key role in supporting microbial activity, nutrient cycling, and plant health, yet little is known about the combined effects of salinization and the addition of artificial root exudates (AREs) on

How the Physical and Chemical Properties Affect the Heavy Metal Content in Surface Water in Different Types of Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Only ~3% of the global land surface is covered by peatlands, yet more than one‐third of global soil carbon is stored in these ecosystems and contaminant filtration can be provided. The extent to which peat humification (Fibric–Hemic–Sapric) is linked to dissolved heavy metals in peatland surface waters has remained poorly quantified at a ...

CARBON AND CARBONATE METABOLISM IN COASTAL AQUATIC ECOSYSTEMS

Annual Review of Ecology, Evolution, and Systematics, 1998
The coastal zone is where land, ocean, and atmosphere interact. It exhibits a wide diversity of geomorphological types and ecosystems, each one displaying great variability in terms of physical and biogeochemical forcings.

Marine coastal ecosystem and ecotoxicology

Ecotoxicology, 2020
Environmental pollution from industrialization, urbanization and agriculture is a serious issue facing all countries during economic development. The Pearl River Delta in Southern China offers a unique case for study and documentation on the ecosystem changes during the fast economic development and urbanization over the past 40 years.

Factors in the Decline of Coastal Ecosystems

Science, 2001
In their review “historical overfishing and the recent collapse of coastal ecosystems,” Jeremy B. C. Jackson and colleagues argue for the “primacy” of overfishing in the collapse, in contrast to pollution, species introductions, climate change, diseases, and other human impacts ...

Seasonality in coastal benthic ecosystems

Trends in Ecology & Evolution, 2000
For historical reasons, knowledge about seasonality in the dynamics of marine benthic suspension feeders from temperate areas comes mainly from studies of cold temperate seas. Recent surveys of Mediterranean taxa show different patterns from those observed in cold temperate seas, which are characterized by winter dormancy.

Microplastics in Singapore’s Coastal Mangrove Ecosystems

Marine Pollution Bulletin, 2014
The prevalence of microplastics was studied in seven intertidal mangroves habitats of Singapore. Microplastics were extracted from mangrove sediments via a floatation method, and then counted and categorized according to particle shape and size. Representative microplastics from Berlayar Creek, Sungei Buloh, Pasir Ris and Lim Chu Kang were isolated for

REGIME SHIFT IN A COASTAL MARINE ECOSYSTEM

Ecological Applications, 2008
We demonstrate changes in ecosystem stable states in a coastal lagoon that are consistent with what a regime shift would hypothesize. In the nutrient-stressed Ringkøbing Fjord, Denmark, a small change in one variable (salinity) facilitated by a change in sluice management, caused a sudden regime shift from a bottom-up controlled turbid state, into a ...

Support underway for coastal ecosystems

Science, 2014
In his perspective “A global strategy for protecting vulnerable coastal populations” (12 September, p. [1250][1]), E. B. Barbier proposes the establishment of a global emergency task force, combined with international financial support to reduce vulnerability in the long-run, as a means to protect coastal populations from the threats posed by climate ...
