This critique of the Green India Mission highlights the international political agenda motivating it as well as how this impacts communities and forest governance. The Government of India announced it’s first ever National Action Plan on Climate Change (NAPCC) in June 2008 to identify measures and steps to advance climate …

Talking REDD+: beyond forestry - joining up and moving forward

This briefing gives an overview of the key REDD+ issues, in particular: integrating mitigation and adaptation actions; addressing tenure; learning from participatory forest management and payment for ecosystems services; taking the right approach to gender; developing safeguards to minimize negative impacts of REDD+; and strengthening South-South collaboration to reduce the …

Contribution of ecosystem restoration to the objectives of the CBD and a healthy planet for all people

In many countries, degraded ecosystems represent immense opportunity for both biodiversity restoration and human health. When properly designed, the restoration of ecosystems is a proven, safe and immediately available means to protect biodiversity and the vital benefits it provides. Restored ecosystems can improve resilience of both ecosystems and societies, and …

Pro-poor benefit distribution in REDD+: who gets what and why does it matter?

Ensuring that the poor or the most vulnerable sections of society benefit from REDD+ projects is crucial to building both national and international legitimacy and to fostering successful delivery of conservation and social objectives. In both academic and non-academic literature, issues of the equity of benefit-sharing at a community or …

Understanding community-based REDD+

The purpose of this manual is to provide guidance to indigenous trainers to prepare and conduct trainings on Community-based REDD+. These trainings should help communities acquire the knowledge and skills needed to take a decision on whether to join a REDD+ project, and if they do, to be able to …

Understanding the nexus: background paper for the Bonn2011 conference - the water, energy and food security nexus

This paper for the Bonn 2011 Conference presents initial evidence for how a nexus approach can enhance water, energy and food security by increasing efficiency, reducing trade-offs, building synergies and improving governance across sectors. It also underpins policy recommendations, which are detailed in a separate paper.

Review of climate change adaptation practices in South Asia

Climate change is predicted to have severe consequences for South Asia, particularly in agriculture, which employs more than 60 per cent of the region’s labour force. Adaptation efforts in South Asia have so far been fragmented, lacking a strong link between national climate change strategies and plans, and existing disaster …

Ecosystem-based approaches to adaptation: compilation of information

This report contains a compilation of information on ecosystem-based approaches to adaptation. With a synthesis of the state of knowledge on ecosystem-based approaches to adaptation, this report provides an overview of how ecosystems can play a role in helping people adapt to climate change, through the compilation of examples and …

The influence of climatic seasonality on the diversity of different tropical pollinator groups

Tropical South America is rich in different groups of pollinators, but the biotic and abiotic factors determining the geographical distribution of their species richness are poorly understood. We analyzed the species richness of three groups of pollinators (bees and wasps, butterflies, hummingbirds) in six tropical forests in the Bolivian lowlands …

Shrinking body size as an ecological response to climate change

Determining how climate change will affect global ecology and ecosystem services is one of the next important frontiers in environmental science. Many species already exhibit smaller sizes as a result of climate change and many others are likely to shrink in response to continued climate change, following fundamental ecological and …

Water toolbox: a contribution to Rio+20

As a contribution to the Rio+20 process, this water toolbox is an output from the UN-Water conference on ‘Water in the Green Economy in Practice: Towards Rio+20’.

Payment for environmental services: first global inventory of schemes provisioning water for cities

This new report is a global inventory of identified Payment for environmental services (PES) —water for cities? schemes and —pre PES water schemes? around the world.

Persistence of soil organic matter as an ecosystem property

Globally, soil organic matter (SOM) contains more than three times as much carbon as either the atmosphere or terrestrial vegetation. Yet it remains largely unknown why some SOM persists for millennia whereas other SOM decomposes readily—and this limits our ability to predict how soils will respond to climate change. Recent …
