Community-led sustainable agriculture to support peatland restoration in Indonesia

Tropical peatlands have been drained and deforested for agriculture across Southeast Asia, resulting in large CO2 emissions and fires. To reverse this, Indonesia has committed to rewet over 2 million hectares of drained peatlands. However, rewetting will necessitate changes to agricultural practices, requiring a balance between emissions reductions and livelihoods. We aim to understand the impacts of peatland rewetting on agriculture and GHG emissions in Indonesia. We will quantify the effects of sustainable agriculture and peatland rewetting on CO2 emissions and build social knowledge to balance agriculture with emissions goals. Our work will inform land management and climate mitigation planning.

Mapping Peat Carbon to Inform Climate-friendly Rural Development in Colombia

Peatland conservation is a priority for climate change mitigation because peat soils contain roughly the same amount of carbon as all forms of terrestrial vegetation. Currently, two knowledge barriers hinder the formulation of sustainable development policies for peatlands. The first is geophysical: we lack a comprehensive understanding of the spatial distribution and carbon stocks of peat deposits, as they are typically found in remote tropical forested regions. The second is socioeconomic: we lack knowledge on sustainable uses of tropical peatlands that avoid large carbon emissions from land-use change. These knowledge limitations coincide with a historic conservation challenge in Colombia - deforestation of rural areas has accelerated dramatically following the end of a multi-decade civil conflict, in one of the most peatland-rich tropical countries. There is an urgent need to develop a carbon-based and socially-informed conservation plan in Colombia that avoids carbon dioxide (CO2) emissions from peatland degradation while alleviating rural poverty. In this project we propose two research activities. First, we will sample two carbon-rich regions of Colombia to build improved maps of peatland area and carbon stocks. Second, we will conduct semi-structured interviews with indigenous and conflict-affected communities living within peatland areas to document local peatland uses and values. Together, these results will provide an empirical foundation for carbon conservation planning and sustainable peatland development in Colombia. This approach will also serve as a model for other peatland-rich tropical countries.
