Plastic pollution is a worldwide environmentalchallenge. In coastal West Africa, about80 percent of plastic waste is mismanaged, posingescalating challenges to people, the economy, andthe coastal and marine environment.This Synthesis Paper was prepared to informdecision-makers from the region...

Plastic waste negatively impacts ecosystems, public health, and local economies in Tanzania. For example, marine plastic and microplastic wastes contaminate beaches, sea grass areas and coral reef habitats, lower the quality of marine ecosystems and biodiversity, and endanger bird and marine...

Coastal wetlands are recognized as carbon sinks that play an important role in mitigating global climate change because of the strong carbon uptake by vegetation and high carbon sequestration in the soil. Over the last few decades, plastic waste pollution in coastal zones has become increasingly...

Large amounts of coastal silt are converted into subgrade soil by cement solidification for resource utilization, while the compressive strength was too low (<1.0 MPa) with as little cement usage as possible (<15%, w/w). Our previous studies have shown that biochar was added into the raw materials to achieve strength enhancement, but the specific mechanisms need to be further explored. Three biochars derived from peanut shells (PSBC), cow dung (CDBC) and sewage sludge (SSBC) at 300°C, 500°C and 700°C pyrolysis, respectively were used as exogenous additives with 1%, 2% and 5%. Results showed that all biochars significantly improved the compressive strength of the subgrade soil products by 20-110%, which was attributed to that biochar catalyzed cement hydration reactions to produce more Ca(OH)2, CaCO3 and calcium silicate hydrates (C-S-H gel). The catalytic capacity of different biochars was SSBC > PSBC CDBC. Due to the suitable specific surface area and porosity of 500°C biochar, it is the most effective for strength enhancement....</1.0>

In the global context, countries must reduce carbon dioxide emissions to "net zero" by 2050 to limit global warming to 1.5°C above pre-industrial levels. China's Nationally Determined Contributions (NDCs) are to peak carbon dioxide emissions by 2030 and achieve the carbon neutrality target by...

The coastal aquaculture is a century old practice in Bangladesh. The environmental condition of south-west coastal region of Bangladesh is suitable for shrimp culture. Therefore, most of the shrimp farms are established in this coastal region. The shrimp activities in the coastal zone of...
