Forest and land fires are among the major catastrophic events that occur in Indonesia. They are a major cause of deforestation and greenhouse gas emissions. Their multiple sources are most diverse and root in nature and society. The immediate fire effects directly and the long-term landscape ecosystem degradations indirectly cause major and persisting and serious problems of public health and ecosystem service. Smoke haze from the forest and land fires in Sumatra and Kalimantan in 2015 caused significant environmental and economic losses in Indonesia, Singapore and Malaysia. We describe the different types of land uses and land cover where fires and smoke haze took place, and how local politics have affected fire use from 2001 to 2017. We calculated hot spots from satellite imageries as proxies for fire occurrences and applied regression analysis to understand the link between fire and local politics in Sumatra and Kalimantan. The results show that the greatest frequency of hot spots occurred in wood and oil palm plantations and logging concessions (47%), followed by conservation areas (31%) and community land (22%). Local elections involve land transactions, and fires were used as a cheap way to increase the land value. The use of fire as means of land clearing was strongly influenced by local politics. Their frequency and abundance obviously increased about a year prior to local elections. The reasons behind the correlation need to be understood so that appropriate incentives and sanctions can be put in place and deter political leaders from using fire as an incentive to their advantage.

Globally, planted forests are increasing, providing increased resources to forest industries and ecosystem services (ES) to local and wider communities. However, assessment of the impacts of plantations on ES has been limited. Planted forests have expanded rapidly in Vietnam over the last 20 years, with much of the planting undertaken by smallholder growers using exotic Acacia and Eucalyptus species. This study aimed to test a framework to assess changes in four ES due to an increase in Acacia plantations from 2005–2015 in central Vietnam: carbon sequestration, sediment retention, water yield and habitat. Quantitative and qualitative indicators for each service were derived from the literature. Results showed that the area of planted forests in Quảng Trị and Thừa Thiên-Huế Provinces increased from 130,930 hectares (ha) to 182,508 ha, mostly replacing non-forest areas (degraded lands, grasslands and agricultural lands) and poor forests. The framework demonstrated capacity to assess the effect of planted forests on wood flow, carbon stocks, sediment retention, streamflow and the extent of wildlife habitat. Apart from the wood supply and carbon sequestration, more research is required to translate biophysical indicators to benefit relevant indicators related to human welfare. The study also revealed that the area of rich forests decreased by 20% over the ten years, mostly through degradation to poorer quality natural forests. Therefore, at the landscape scale, improvement in ES due to conversion of non-forests to planted forests was offset by a reduction in some services as a result of degradation of native forest from rich to poorer condition. Assessment of changes in ES due to planted forests also needs to consider other landscape changes. These analyses can inform policymakers, forest owners and managers, environmental organizations and local communities of the benefits and impacts of planted forests and provide an improved basis for payments for ES and potential additional income for smallholder tree growers.
