Catastrophic uncontrolled fires are a leading social-environmental challenge that now occur even in the humid tropics. In 2015 extensive Indonesian peatland fires commanded national and international attention and resulted in a ban on all burning in the country extending to traditional farmers practicing small-scale fire-based agriculture on mineral soils. However, the impacts of, and responses to the ban on these fire-dependent communities is not well understood. Understanding the mental models of communities exposed to environmental change and its corresponding policy responses can provide salient insights into the place-based experience of change to identify contested perceptions and serve to improve the distributional equity of associated impacts. We assessed the mental models of Dayak farmers in Kapuas Hulu, Kalimantan, in three distinct landscape contexts: i) oil palm (OP), ii) national park (NP), and iii) transition (T) sites. These locations enabled insights into how different contemporary landscape contexts and livelihood opportunities are related to experiences and coping strategies. We collected data using the Conceptual Content Cognitive Mapping approach in two communities in each landscape context (n = 24 participants per landscape), and 72 interviews in total. Results show that the NP and T sites were most similar, whilst the OP communities held distinct perceptions of fire. In addition to the agricultural value of fire, cultural and relational values are associated with fire use across sites and would be severed through fire prevention. Finally, we show that the burdens of the burn ban for farmers and forests were most pronounced in the NP and T sites where farmers are most reliant on traditional agriculture, have the fewest livelihood alternatives and least external support to fight uncontrolled fires.

Prescribed burning and integrated fire management in the Brazilian Cerrado: demonstrated impacts and scale-up potential for emission abatement
Fire management has proven successful in reducing deforestation, preserving biodiversity and mitigating greenhouse gas (GHG) emissions. After years of zero burning policies in fire-adapted ecosystems, and resulting increases in fire hazards and risks, countries are moving towards integrated fire management (IFM) including prescribed burning (PB). With a primary focus on biodiversity, Brazilian governmental organizations endorsed this paradigm shift in 2014, with the introduction of IFM in a number of protected areas (PA) of the Cerrado. Reducing high intensity mid/late dry season (M/LDS) fires through PB in the early dry season (EDS) has proven successful in other savanna ecosystems, with demonstrated mitigation potential as EDS fires are associated with lower GHG emissions. In the present study, Earth observation data were used to analyze the seasonality of active fires, burned areas and fuel loads. A dynamic performance benchmark (control-treatment paired sample test) was applied to assess the effectiveness of existing IFM activities in promoting emission abatement over the pre-covid period 2014–2019. Compared against the responses of PAs without IFM-PB, the PAs with IFM-PB showed significant increases in EDS fires (+137% hotspots) and EDS burned areas (from a share of 11.2% to 29.5% of the total yearly burned area). Fuel fragmentation through EDS-PB, tracked through calibrated fuel load maps, also led to a 62% reduction in burned areas in the IFM period 2014–2019. Combined M/LDS burned areas decreased from 85.1% of the total yearly burned area to a share of 67.7%. When applying the observed shift in fire seasonality and the effect of burned area reduction to all the PA of the Cerrado for the same period, we estimate an emission abatement potential of 1085 764 tCO2e/y. Given the fact that IFM followed a biodiversity-centred approach in the Cerrado, an emission abatement-centered approach could result in even higher abatement potentials.
Sustainable land preparation for farmer-managed lowland agriculture in Indonesia
In almost all forms of agriculture and farming practice, land clearing is the initial step. In Indonesia, in general, the most cost effective means of clearing land is through the use of fire. However, this use of fire often results in uncontrolled outbreaks, particularly in lowland areas especially and during prolonged dry seasons. In recent years, these uncontrolled fire outbreaks have had a catastrophic environmental, social and economic impact. The Indonesian government has expressed a strong commitment to controlling these outbreaks, as demonstrated by a broad set of laws, regulations, decrees, guidelines, and directives to control and manage land and forest fire. However, despite these measures, the occurrence of widespread, high-intensity fire outbreaks is still unacceptably high. This study assessed land-clearing techniques associated with a low risk of fire outbreaks, comparing the costs associated with a range of these techniques. It then analyzed intervention options that would involve the adoption of these techniques by farmers. These low-risk techniques included: (i) zero-burning practices involving traditional machinery and farmer groups; (ii) zero-burning involving modern machinery and partnerships with government agencies/private enterprises; (iii) controlled burning; and (iv) the chemical removal of biomass using herbicides. The study finds that the costs for all four of these options are higher than with land-clearing techniques that use fire alone. However, it also showed that the cost implications for farmers could be mitigated by taking a more holistic view of farming practices as a system, rather than focusing only on land-clearing practices in isolation. It found that when land-clearing practices that involve low risks of fire outbreak are combined with good agricultural practices (GAP), farmers could still achieve higher levels of profitability and productivity than under a business as usual (BAU) scenario. The study produced scenarios involving BAU practices; land clearing without fire and with BAU practices; and land clearing without fire and with good agricultural practices (GAP) for four agricultural commodities (oil palm, cocoa, rubber, and paddy). It found that the return on land (NPV) in the case of the scenario involving land clearing without fire and with GAP was still higher than under the BAU scenario, except in the case of rubber, with which the NPV was higher in the scenario with modern machinery and GAP. The study concludes that a systems approach is necessary to effectively control fire outbreaks. Government programs should be designed and implemented on the basis of this systems approach with the involvement of a wide range of stakeholders, including through partnerships with the private sector operators, to effectively control the risk of fire outbreaks while at the same time supporting farmers’ livelihoods by ensuring that they are enabled to generate higher levels of productivity and profitability from their land.
