Peatland plays an important ecological and economic role in many countries all over the world. At the same time, due to various human and non-human interventions, peatland is also a fragile ecosystem, which is currently facing severe problems, such as deforestation, fires, and peat subsidence. Peat subsidence is currently one of the most severe but least recognized issues.

Myanmar is losing its natural forests, with devastating impacts on the lives of millions of people. The losses are killing the country’s rich biodiversity and undermining its economy. One of the main drivers is weak governance.

In the face of increasing socio-economic and climatic pressures in growing cities, it is rational for managers to consider multiple approaches for securing water availability.

Agroforestry, relative to conventional agriculture, contributes significantly to carbon sequestration, increases a range of regulating ecosystem services, and enhances biodiversity.

Researchers and policy makers are increasingly looking at the drivers of forest recovery (or forest transition) for inspiration in their search for win-win solutions to deforestation. However, causal generalizations regarding forest transitions are subject to significant problems.

Deforestation is recognized as a major driver of the loss of biodiversity and ecosystem services. It also disturbs natural processes such as biogeochemical, hydrological, and ecological cycles. In Malawi, deforestation is estimated to be responsible for the loss of 33,000 hectares per year, and is mainly attributed to agriculture expansion, tobacco growing, and excessive use of biomass.

การจัดการลุ่มนํ้าที่มีเป้าหมายเพื่อความยั่งยืนโดยมีแนวคิดการจัดการลุ่มนํ้าที่ไม่ได้แยกส่วนทรัพยากรนํ้าออกจากทรัพยากรอื่นในระบบนิเวศลุ่มนํ้า เช่น ความหลากหลายทางชีวภาพ ที่ดิน ป่าไม้ และวิถีชีวิตผู้คนซึ่งเป็นทั้งฐานคิดและเครื่องมือที่มีประสิทธิภาพในการใช้และดูแลลุ่มนํ้าอย่างยั่งยืน เพื่อความเข้าใจเรื่องการจัดการลุ่มนํ้าว่าคืออะไร จัดการอะไร จัดการอย่างไรจึงจะพิสูจน์ได้ว่าเป็นการจัดการลุ่มนํ้าแบบย

This edition of Unasylva comes in the wake of the United Nations Conference on Sustainable Development, Rio+20,which, among other things, produced a document called The Future We Want.

In the last 40 years, large areas of the Mau forest, the largest contiguous tropical montane forest in East Africa, have been cleared for agriculture. To date, there are no empirical data on how this land use change affects carbon dioxide (CO2) fluxes from soil respiration and soil methane (CH4) fluxes.

In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed.
