Increasing agricultural production in the European Union while reducing imports implicated in tropical deforestation (see R. Fuchs et al. Nature 586, 671–673; 2020) risks undermining the United Nations' sustainable development goals (SDGs). These include the reduction of poverty and hunger, and the conservation of ecosystems.

Deforestation, forest degradation, and land-use change are a major source of carbon emissions. The Copenhagen Accord recognised the crucial role of reducing emissions from deforestation, emphasized the role of forests in climate change mitigation, and called for the immediate establishment of a REDD+ mechanism. Most likely, it will form an integral part of the future climate change regime. For many developed countries, REDD+ seems to be an attractive option to achieve part of their reduction targets through investments in developing countries. For some developing countries, this offers an additional source of financing to support sustainable forest management and to boost their development plans and poverty-reduction strategies. This paper analyses the challenges and major gaps that developing countries are facing when planning their national strategies for the implementation of REDD+ schemes. We conclude that REDD+ as a climate change mitigation instrument will only be able to proceed at a pace that allows the meaningful participation of all relevant stakeholders in consensus-building. When the REDD+ enters the markets, the rights of local communities to forest land and carbon will need to be clarified and secured. Successful implementation of REDD+ will, in most cases, require strengthening the stake of local communities for managing their forest carbon assets and allowing them to benefit fully from emerging carbon markets and other funding schemes. Governments will need to renew their institutions and adopt new approaches to handle these challenges by including the role of forests in climate change mitigation as an integral part of their development plans and policies.

In September and October 2015, widespread forest and peatland fires burned over large parts of maritime southeast Asia,most notably Indonesia,releasing large amounts of terrestrially-stored carbon into the atmosphere, primarily in the form of CO2, CO and CH4. With a mean emission rate of 11.3 Tg CO2 per day during Sept-Oct 2015, emissions from these fires exceeded the fossil fuel CO2 release rate of the European Union (EU28) (8.9 Tg CO2 per day) . Although seasonal fires are a frequent occurrence in the human modified landscapes found in Indonesia,the extent of the 2015 fires was greatly inflated by an extended drought period associated with a strong El Niño. We estimate carbon emissions from the 2015 fires to be the largest seen in maritime southeast Asia since those associated with the record breaking El Niño of 1997. Compared to that event, a much better constrained regional total carbon emission estimate can be made for the 2015 fires through the use of present-day satellite observations of the fire's radiative power output and atmospheric CO concentrations, processed using the modelling and assimilation framework of the Copernicus Atmosphere Monitoring Service (CAMS) and combined with unique in situ smoke measurements made on Kalimantan.

To align with international climate efforts to remain within 1.5 degrees of the earth temperature, Indonesia requires concerted measures from actors to preserve and restore carbon rich ecosystems, especially blue carbon ecosystem. Although studies have suggested the importance of blue carbon ecosystems in contributing to Indonesian climate action, translating science to policy remains a challenge. Mapping actors and the pattern of information exchange related to blue carbon can help identify potential barriers in the blue carbon governance process and policy development. This study uses Social Network Analysis and integrates it with results from in-depth qualitative evaluation of institutional respondents. Data is obtained through questionnaires and semi-structured interviews with representatives from a broad range of organizations. It was found that the actor who oversees the fulfilment of the climate commitment, which is the most common objective of the network, is not a central actor. Second, the actors with the highest degree of centrality received little trust from other actors. Third, overall, the network has low quality ties. Each of these hinders knowledge providers' ability to make an impact on policy development. By critically examining the interactions between actors, this research casts new light on the overlooked problem of the significance of the network in blue carbon governance process.

This publication has two objectives. First, it analyzes the past research on deforestation and summarizes the findings of that research, in terms of its relevance to the development of future REDD regimes. Second, it highlights areas where future research and methodological development are needed to support national and international processes on avoided deforestation and degradation.

Transboundary pollution from vegetation fires is a recurrent and highly politicised environmental problem in Southeast Asia. This paper is a critical synthesis of the policy response to the severe haze episodes of 1997/1998. It is based on a series of science–policy activities co-ordinated by the Global Change Impacts Centre for Southeast Asia aimed at exploring land-use planning and management options to reduce the impacts of transboundary pollution from vegetation fires. We begin with a brief summary of what is known about the causes of the fires and haze, the composition and distribution of haze, and the main impacts. Policy options and instruments are considered at a range of levels, from local waste-wood management options and national land development strategies, through to regional and international institutions. In these analyses, we seek to understand the interaction of different interest groups and identify potentially complementary policies as well as likely tradeoffs. Ultimately, the aims of these activities are improvement of the public policy process and greater relevance of research activities and research-based knowledge.

The most prominent international responses to climate change focus on mitigation (reducing the accumulation of greenhouse gases) rather than adaptation (reducing the vulnerability of society and ecosystems). However, with climate change now inevitable, adaptation is gaining importance in the policy arena, and is an integral part of ongoing negotiations towards an international framework. This report presents the case for adaptation for tropical forests (reducing the impacts of climate change on forests and their ecosystem services) and tropical forests for adaptation (using forests to help local people and society in general to adapt to inevitable changes). Policies in the forest, climate change and other sectors need to address these issues and be integrated with each other—such a cross-sectoral approach is essential if the benefits derived in one area are not to be lost or counteracted in another. Moreover, the institutions involved in policy development and implementation need themselves to be flexible and able to learn in the context of dynamic human and environmental systems. And all this needs to be done at all levels from the local community to the national government and international institutions. The report includes an appendix covering climate scenarios, concepts, and international policies and funds.

Until recently, tropical peat swamp forests in Indonesia have been subject to increasing pressure from land-use change and excessive drainage. This has increased greenhouse gas (GHG) emissions and risk of fires. Five tropical peat landscapes under different management regimes were selected and assessed with regards to GHG emissions and vulnerability to fire. Converted peat swamp forest emitted CO 2 at a similar rate to primary and secondary peat swamp forests. Total emissions ranged between 41 and 52 Mg CO 2 /ha/yr, and 85% of this was from heterotrophic respiration. Managing groundwater levels (GWL) is crucial to GHG mitigation actions. Peatland fire risk is closely associated with GWL, and fire risk can be reduced by 30% when peat rewetting is prioritized in the most vulnerable areas. Lack of coordinated water management could lead to uncontrollable GWLs, peat subsidence, and fires, causing large GHG emissions and other environmental degradation. Government-initiated Forest Management Units could manage peatlands at a regional level. Compliance mechanisms need to be institutionalized to control emissions, land subsidence, and fire incidence.
