wetlands in the lower reaches of songhua river (lrsr), northeast china, are rich in biodiversityand natural resources, which provide crucial staging and wintering habitats for various endangered species.however, in the past five decades, the size of this wetland area has decreased, and its quality has deteriorated because of increased natural and human activities. wetland restoration is critica...
Although mangroves dominated by Avicennia germinans and Rhizophora mangle are extending over 6000 ha in the Tanbi Wetland National Park (TWNP) (The Gambia), their importance for local populations (both peri-urban and urban) is not well documented. For the first time, this study evaluates the different mangrove resources in and around Banjul (i.e., timber, non-timber, edible, and ethnomedicinal ...
In July of 2013, Taiwan passed its Wetland Conservation Act and will begin the implementation of the Act on 2 February 2015. With this Act, Taiwan has become the second Asian country to have specific legislation on wetland conservation and protection. This new law enables the society to achieve sustainable utilization on wetland ecological services. The core concepts of the Wetland Conversation...
Constructed wetland plays an important role in the removal of micro-polluted water pollutants urban sources. However, purification capacity and influencing factors constructed wetlands still need to be explored. This study monitored turbidity, ammonia nitrogen (NH3-N), dissolved oxygen (DO), chemical demand (COD) at inlet outlet Shijiuyang Wetland Jiaxing City from 2019 2021. The results showed...
The reuse of domestic and industrial wastewater in urban settings of the developing world may harm the health of people through direct contact or via contaminated urban agricultural products and drinking water. We assessed chemical and microbial pollutants in 23 sentinel sites along the wastewater and faecal sludge management and reuse chain of Kampala, Uganda. Water samples were examined for b...
The applications of object-based image analysis (OBIA) in remote sensing studies of wetlands have been growing over recent decades, addressing tasks from detection and delineation of wetland bodies to comprehensive analyses of within-wetland cover types and their change. Compared to pixel-based approaches, OBIA offers several important benefits to wetland analyses related to smoothing of the lo...
Both anthropogenic activities and climate change can affect the biogeochemical processes of natural wetland methanogenesis. Quantifying possible impacts of changing climate and wetland area on wetland methane (CH4) emissions in China is important for improving our knowledge on CH4 budgets locally and globally. However, their respective and combined effects are uncertain. We incorporated changes...
