This study aimed at establishing why wetland degradation persists in Uganda despite Ramsar and other policy interventions. The objectives were to assess local peoples’ attitudes towards wetlands; the level of illegal activities contribution management programs projects household incomes. We used a cross-sectional mixed methods design targeted 120 respondents, including residents opinion leaders...
The federal government requires those who destroy wetlands to preserve, restore, or create new ones with the goal of no net loss of wetlands. In the summer of 2000, we tested whether forested wetlands created an average of 8 years earlier had developed avian communities similar to natural wetlands of the same age in southeastern Virginia. We compared six created wetlands to five natural (refere...
Ecosystem resilience to pressures expanding and contracting within the adaptive cycle as slow variables change. However, little is known about their role in defining reference conditions for wetland restoration. Here, we applied paleoecological data of two wetlands that have been degraded (Honghe, riparian peatland) disappeared (Shenjiadian, valley evaluate ecosystem anthropogenic phases progre...
Abstract Background Coastal wetlands with high biodiversity and productivity provide essential ecosystem services that have a significant positive socio-economic impact. However, coastal reclamation, pollution, climate change are threatening wetlands. Thus, it is critical to identify priority areas for restoration improve habitat resilience adapt environmental changes. Here, we propose general ...
Purpose of wetland creation and restoration and expected results (protection vs. nourishment) Riparian ecosystems generally compose a minor proportion of surrounding areas, but typically are more structurally diverse and more productive in plant and animal biomass than adjacent upland areas. Riparian areas supply food, cover, and water (especially important in the arid regions) for a large dive...

Here, we demonstrate that reductions in the depth of inlets or estuary channels can be used to reduce or prevent coastal flooding. A validated hydrodynamic model of Jamaica Bay, New York City (NYC), is used to test nature-based adaptation measures in ameliorating flooding for NYC’s two largest historical coastal flood events. In addition to control runs with modern bathymetry, three altered lan...
We have developed a computer model of plant community dynamics for Louisiana’s coastal wetland ecosystems. The model was improved as a part of the Louisiana Coastal Master Plan of 2017 and is one of several linked models used to evaluate the potential effects of climate change and sea levels rise as well as the potential effects of alternative approaches to managing the region’s natural resourc...
