We evaluated a program of payments for ecosystem services in Uganda that offered forestowning households annual payments of 70,000 Ugandan shillings per hectare if they conserved their forest. The program was implemented as a randomized controlled trial in 121 villages, 60 of which received the program for 2 years. The primary outcome was the change in land area covered by trees, measured by classifying high-resolution satellite imagery. We found that tree cover declined by 4.2% during the study period in treatment villages, compared to 9.1% in control villages.

Elaborated in the framework of the UNDP-UN Environment “Poverty Environment Initiative” (PEI), this publication identifies entry points to integrate environmental sustainability and social protection goals.

The strong focus on species extinctions, a critical aspect of the contemporary pulse of biological extinction, leads to a common misimpression that Earth’s biota is not immediately threatened, just slowly entering an episode of major biodiversity loss. This view overlooks the current trends of population declines and extinctions.

This framework document has been prepared by the team at ICIMOD working on various aspects of ecosystem management in collaboration with the United Nations Environment – World Conservation Monitoring Centre (UNEP–WCMC), with technical inputs from eminent ecologists, gender and governance specialists, sociologists and economists from the region.

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.

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).

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
