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.

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).

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).

New WWF report shows EU protected areas at risk due to lack of proper implementation of EU laws, series of wrongdoings by member states, and legal actions started by the Commission. It also illustrates the importance of nature protection and sustainable development going hand in hand.

Sustainable land management practices can be enhanced by reconciling environmental and development objectives while incorporating climate resilience. A growing international consensus indicates a need to look at the bigger picture and not just treat sectors selectively and independently.

In our recent perspective article,  we noted that most (approximately 60 percent) terrestrial large carnivore and large herbivore species are now threatened with extinction, and we offered a 13-point declaration designed to promote and guide actions to save these iconic mammalian megafauna (Ripple et al. 2016). Some may worry that a focus on saving megafauna might undermine efforts to conserve biodiversity more broadly.

The purpose of this study was to estimate the benefits and costs of reducing deforestation and forest degradation in different landscapes and management regimes in Nepal, and to provide associated opportunity costs of carbon that can be used as inputs for planning the implementation of REDD+ in Nepal.
