Global forest loss impacts climate, biodiversity and sustainable development goals. Deforestation footprinting attributes forest loss to commodity production and consumption, identifying global trends, drivers and hot spots to inform zero-deforestation policies. In this Review, we provide an overview of global deforestation footprinting approaches and their trends. Major economies, including Brazil, Indonesia, China, the United States and Europe, are responsible for most commodity-linked deforestation, with agriculture-linked deforestation in Brazil alone reaching over 12.8 million hectares between 2005 and 2015. Agriculture is a dominant driver of deforestation. For example, 86% of global deforestation occurring between 2001 and 2022 can be attributed to crop and cattle production. Footprinting of commodity-linked deforestation has contributed to the scope and implementation of supply chain regulation to mitigate forest loss. For example, footprint estimates have been used in risk assessments for EU and UK due diligence regulations. Although forest loss to agriculture is relatively well documented, a lack of data on non-agricultural drivers — such as mining and mangrove clearance for aquaculture — limits the scope of footprints in fully attributing total global forest loss to human activities. Future research should focus on methodological and data harmonization, transparency and sharing to enable footprinting approaches to cover a wider range of deforestation drivers.

    Understanding and acting on biodiversity loss requires robust tools linking biodiversity impacts to land use change, the biggest threat to terrestrial biodiversity. Here we estimate agriculture’s impact on the Brazilian Cerrado’s biodiversity using three approaches—countryside Species-Area Relationship, Species Threat Abatement and Restoration and Species Habitat Index. By using same input data, we show how indicator scope and design affects impact assessments and resulting decision-support. All indicators show agriculture expansion’s increasing pressure on biodiversity. Results suggest that metrics are complementary, providing distinctly different insight into biodiversity change drivers and impacts. Meaningful applications of biodiversity indicators therefore require compatibility between focal questions and indicator choice regarding temporal, spatial, and ecological perspectives on impact and drivers. Backward-looking analyses focused on historical land use change and accountability are best served by the countryside-Species Area Relationship and the Species Habitat Index. Forward-looking analyses of impact risk hotspots and global extinctions mitigation are best served by the Species Threat Abatement and Restoration.

    Explaining the recent reduction of Indonesia’s deforestation

    Deforestation in Indonesia has declined sharply since 2015-2016. We use a combination of spatial land use change data, interviews with stakeholders and statistical analysis to explain this reduction.The exact extent of the reduction in deforestation depends on the data set used, and the years or time periods compared, varying between 40% and 90%. A robust estimate is that deforestation has fallen by at least 50% since ca. 2016.The decline is uneven across islands and provinces. The two main “deforestation islands” Kalimantan and Sumatra experienced a major decline, with a relatively larger decline in the former. The provinces with the largest absolute decline were Riau, South Sumatra and Central Kalimantan, followed by West and East Kalimantan.In terms of commodities driving deforestation (“direct drivers”), palm oil is still the most important commodity (46% for 2018-2022, according to MapBiomas Indonesia data, compared to 55% for the period 2010-2017).Pulp is on the rise as a deforestation driver, particularly in Kalimantan. In the three high deforestation provinces on that island, the demand for pulp was behind almost 1/3 of the natural forest conversion in 2022.Mining for coal and valuable minerals such as nickel is also on the rise, with MBI data suggesting its share of national deforestation being 5.4% (2021-2022), compared to less than one (0.9%) for the 2010-2017 period. Mining is particularly important in Sulawesi, where it according to one estimate accounted for 30% of the deforestation in 2021-2022.Five hypotheses are put forward to explain the reduction, related to public policies, private (corporate) policies, civil society pressure, commodity prices, and forest scarcity.New public (government) policies have been a main reason for the decline. The moratorium of new permits of primary forest and peatlands in 2011 has had an impact, but also took time to produce an effect on the ground effect (in part as it was a ban on issuing new licences). Interviewees also stressed that better sectoral coordination related to the moratorium and other reforms has been key for the slowdown.A second set of reforms relate to fire management and peatland protection, sparked by the devastating 2015 forest fires. The interviewees highlight this as a key policy reform by, for example, increasing the accountability of subnational government officials for fire management.Results-based payments (RBP) or result-based contributions were central in the Letter of Intent between Indonesia and Norway in 2011 and in the new MoU of 2022, although the first payment was not made before in 2022. An RBP-based project of more than USD 100 million was approved by the Green Climate Fund in 2020. RBP has also been implemented at subnational level starting in East Kalimantan and Jambi with external donor support. Some reports indicate positive results, although they are likely to be too location-specific and came too late to have had major impacts on the observed decline in national deforestation figures since 2016.Private regulation such as certification and corporate pledges show promising signs with an increasing share of oil palm plantations being certified. Yet, breached are reported, and the forest encroachment factor (i.e., the share of new land being converted from forest) has not dropped as much as to be expected. Moreover, certification of pulp production and mining is lagging behind.Civil society pressure has played a role in particularly two areas, although the exact role and contribution are hard to assess. First, CSOs are active actors on the policy arena, also to influence private sector initiatives and policies. Second, CSOs are important watchdogs for both implementation of public and private regulations and pledges. This has helped “bringing the forests to the court”, as one interviewee observed.Key commodity prices were relatively stable during the 2016-2020 period, and thus cannot explain much of the decline. Yet, no major increase in the prices of deforestation-risk commodities made the implementation of both public and private policies less costly (both for politicians and producers), and made violations of laws and regulations less profitable, increasing policy effectiveness.The prices of coal and minerals such as gold and nickel have, however, increased steadily over the period. The nickel price quadrupled between 2016 and 2022. The increasing role of mining in deforestation can largely be explained by the high and increasing profitability, and demand is likely to grow steadily in the coming years due to the global energy transition.The statistical analysis suggests that up to 1/3 of the reduction in deforestation can be explained by forest scarcity (forest transition). When a province hits ca. 40% forest cover, deforestation tend to decline.While we conclude that all five hypotheses put forward are relevant to explain the recent decline in deforestation, we tentative conclude that public polices – in combination with a forest transition (scarcity) effect – has been the most important factors. Private policies show more mixed results. Behind the public and private policy changes, civil society has played a key role in policy reforms and in promoting more effective implementation though its watchdog role. Non-increasing agricultural commodity prices have made the implementation of forest conservation policies less costly.Deforestation is still a profitable activity for land users and (sub)national governments, and forest conservation is a continuous battle, with future challenges emerging: the effectiveness of current policies may weakened over time, political priorities may change, prices of deforestation-risk commodities may rise, and the composition of direct drivers change – requiring a shift in the policy focus.
