CHENNAI: In a bid to restore biodiversity in Gulf of Mannar, the State Environment Department has kickstarted a Rs 24.74 crore project to rejuvenate the coastal ecosystem.

Ecosystem carbon carrying capacity (CCC) is determined by prevailing climate and natural disturbance regimes, conditions that are projected to change significantly. The interaction of changing climate and its effects on disturbance regimes is expected to affect forest regeneration and growth, which may diminish forest carbon (C) stocks and uptake. We modeled landscape C dynamics over 590 years along the latitudinal gradient of the U.S. Sierra Nevada Mountains under climate and area burned by large wildfires projected by late 21st century.

Cities depend on a healthy natural environment that continuously provides a range of services or benefits to society and the economy. Managing the urban environment is, however, a complex task.

Africa is urbanizing late but fast.

Urban waters remain widely impaired by excess nutrients, despite substantial management efforts. We present a comparison of urban watershed nitrogen (N) and phosphorus (P) budgets. Household actions of lawn fertilization and pet ownership were responsible for the majority of watershed N and P inputs, respectively. N and P exhibited contrasting dynamics within watersheds. Watersheds exported most or all P inputs via stormwater runoff, likely contributing to surface water degradation.

The Draft National Biodiversity Offset Policy has been published for public comment, the Department of Environmental Affairs said. The draft policy was published in Government Gazette 40733 (Notice No. 276), in terms of the National Environmental Management Act, 1998 (Act No. 107 of 1998) (NEMA).

Healthy ecosystems play an essential role in increasing the resilience of people to climate change. Climate change, however, can damage the ability of ecosystems to provide life-supporting services and to protect society from climate-related stressors.

This report shows that improved wastewater management is as much about reducing pollution at the source, as removing contaminants from wastewater flows, reusing reclaimed water and recovering useful by-products

To explain diversity in forests, niche theory must show how multiple plant species coexist while competing for the same resources. Although successional processes are widespread in forests, theoretical work has suggested that differentiation in successional strategy allows only a few species stably to coexist, including only a single shade tolerant. However, this conclusion is based on current niche models, which encode a very simplified view of plant communities, suggesting that the potential for niche differentiation has remained unexplored.

This document presents a framework for the use of science and technology for disaster risk reduction and resilient development for Pacific Island Countries. It aims to support the implementation of both the Sendai Framework for Disaster Risk Reduction and the Framework for Resilient Development (FRDP).
