Envisioning a future for Bornean orangutans: Conservation impacts of action plan implementation and recommendations for improved population outcomes

Populations of the Critically Endangered Bornean orangutan (Pongo pygmaeus) are declining despite more than 10 years of conservation action plan implementation. Here we analyzed the impacts on species' population and habitat from orangutan conservation strategies implemented between 2007 and 2017. We also assessed data on investments into orangutan conservation, orangutan population trends and landcover change in orangutan range between 2007 and 2017. Diverse strategies addressed the range of threats to orangutans but were not implemented at scales that impacted species’ level populations and habitats. Since 2007 orangutan populations and forests across orangutan range have declined, with orangutan killing and deforestation as the major drivers of loss. Protected areas have increased since 2007, notably in Malaysian range states and in Central Kalimantan, Indonesia. However, 80% or tens of thousands of orangutans live outside protected areas in Kalimantan alone. Our results underscore scientific findings that have demonstrated this species’ resiliency and modified previous understanding of their habitat use. Orangutans are regularly found using agriculture landscapes (acacia, oil palm, and timber plantations), and exploited forests. This plasticity must be considered to design more effective orangutan conservation strategies. We need to revise the notion of “orangutan habitat” to extend beyond forests alone, incorporating all landscapes where P. pygmaeus can be found. Orangutans cannot survive in exclusively monoculture production areas; they need some natural forest to fulfill their ecological requirements. However, individuals surviving in isolated forest patches or mosaic landscapes play an important role in sustaining the long-term viability of the local metapopulation through provision of crucial genetic, reproductive and socioecological connectivity. Our findings suggest removing these individuals through translocations weakens overall metapopulation health. All necessary efforts must be made to maintain individuals in isolated forest patches or mosaic landscapes in order to support healthy metapopulations. Improved orangutan population outcomes will require addressing habitat connectivity at the landscape level, incorporating both non-forested and anthropogenically modified areas, and developing efficient management strategies for human and orangutan co-existence within these multiple-use landscapes

Mainstreaming biodiversity in business decisions: taking stock of tools and gaps

Most businesses depend on biodiversity, either directly, indirectly as ecosystem services, or through their supply chains. In negatively impacting biodiversity, businesses risk losing essential resources and services. As a result, it is important for the private sector to demonstrate strong and improved performance on biodiversity. This paper reviews and compares tools and approaches that help businesses measure their performance on biodiversity issues. Through a literature review and interviews of tool developers, we assess how tools are constructed, how they measure biodiversity performance, how and where they are being used by different businesses and how they contribute to achieving international targets for biodiversity. We found that tools perform a range of functions and are mostly applied at product, site, and supply chain level. Further efforts are needed to align tools with global biodiversity goals. Key knowledge gaps remain to better capture dependence on biodiversity and spatial spillover effects

Evaluating the effectiveness of palm oil certification in delivering multiple sustainability objectives

Industrial oil palm plantations in South East Asia have caused significant biodiversity losses and perverse social outcomes. To address concerns over plantation practices and in an attempt to improve sustainability through market mechanisms, civil society organisations and industry representatives developed the Roundtable on Sustainable Palm Oil (RSPO) in 2004. The effectiveness of RSPO in improving the sustainability of the palm oil industry is frequently debated and to date, few quantitative analyses have been undertaken to assess how successful RSPO has been in delivering the social, economic and environmental sustainability outcomes it aims to address. With the palm oil industry continuing to expand in South East Asia and significant estates being planted in Africa and South America, this paper evaluates the effectiveness of RSPO plantations compared to non-certified plantations by assessing the relative performance of several key sustainability metrics compared to business as usual practices. Using Indonesian Borneo (Kalimantan) as a case study, a novel dataset of RSPO concessions was developed and causal analysis methodologies employed to evaluate the environmental, social and economic sustainability of the industry. No significant difference was found between certified and non-certified plantations for any of the sustainability metrics investigated, however positive economic trends including greater fresh fruit bunch yields were revealed. To achieve intended outcomes, RSPO principles and criteria are in need of substantial improvement and rigorous enforcement

Public opinion on protecting iconic species depends on individual wellbeing: perceptions about orangutan conservation in Indonesia and Malaysia

Public opinion has the potential to shape conservation policy-making and implementation. At a local scale, it is argued that human wellbeing is important for conservation success. However, little research has explored how social factors like wellbeing shape public opinion at cross-national scales. Here, we focus on orangutan conservation, where an iconic species near extinction exists amidst complex social issues. We surveyed 2073 Indonesian and Malaysian residents and assessed three indicators of conservation support: policy support, willingness to act for the environment, and willingness to act for orangutans. We then examined how diverse indicators of wellbeing shaped support for orangutan conservation. Our results show that diverse indicators of wellbeing are related to public opinions supportive of conservation in Indonesian and Malaysian citizens. Consistent with our hypotheses, both physical (having basic needs met) and psychological (being free from worry, feeling safe, a sense of agency) wellbeing were positively associated with all three indicators of conservation support. Contrary to common assumptions, not all wellbeing indicators were related to conservation support; we found no evidence that subjective health was positively associated with conservation support. Overall, these findings indicate that social factors such as wellbeing might have an important influence on public opinion about conservation issues, and subsequently, environmental policy-making. Our findings highlight the complexity of the relationship between wellbeing and public opinion, alongside the need to consider multi-dimensional aspects of wellbeing across diverse social and geographic settings

Killing of orangutans in Kalimantan: community perspectives on incidence and drivers

Despite decades of conservation management, many orangutan populations are on the brink of extinction. This is primarily due to habitat loss and direct killings. A study from 2008/2009 suggested that killing was impacting orangutan populations at a rate sufficient to cause local extinctions. As an illegal and taboo behavior that is difficult to measure, killing has been severely understudied since. We conducted 431 interviews in 79 villages across Kalimantan in 2020/2021. Ours is the first quantitative field study in more than 10 years to assess the state of killing of orangutans. We aimed to: (1) assess the current state of killing of orangutans in Kalimantan and compare this to the previous study; (2) determine whether conservation projects are affecting killing; and (3) explore drivers of killing. We examined killing of orangutans across villages with forest conservation projects, orangutan conservation projects, and no conservation projects. We assessed the existence of killing and used scenarios to examine perceived norms about illegal behavior relating to orangutans. We then used matching techniques to assess whether projects have any impact on these indicators. Overall, our findings suggest that killing has occurred in recent times, and our data does not indicate a clear attenuation of the behavior. As such, we argue that killing may still present a substantial threat to Bornean orangutan populations. We also found no statistically significant evidence that conservation projects are reducing killing. Conservation project managers could seek to understand the drivers of killing, and to invest in interventions that address these drivers. Research suggests that current allocation of conservation funding has been ineffective at abating orangutan population decline. We argue that a key part of improving Bornean orangutan conservation practice involves directly addressing killing of orangutans and the underlying drivers of killing

Does oil palm agriculture help alleviate poverty? A multidimensional counterfactual assessment of oil palm development in Indonesia

Palm oil producing countries regularly promote the positive impact of oil palm agriculture on poverty alleviation, despite limited evidence about the contribution of this crop on village well-being. Past evaluations that quantify the social impact of oil palm are dominated by localized studies, which complicate the detection of generalizable findings. Moreover, only a few of these evaluations are based on rigorous case-control studies, which limits the robustness of the conclusions. Here we examined the association between the development of oil palm plantations and change in objective or material well-being between 2000 and 2014 across villages in Kalimantan, Indonesian Borneo. We applied a matching method to evaluate the impacts of oil palm plantations across different aspects of well-being, accounting for varying time delays in the accrual and realization of benefits after plantation development. Our study reveals that the social impacts of oil-palm plantations are not uniformly positive, nor negative, and have varied systematically with biophysical locations and baseline socioeconomic conditions of nearby communities prior to oil palm development. Plantations developed in villages with low to moderate forest cover, in which the majority of communities already relied on market-oriented livelihoods, were associated with improved socioeconomic well-being compared to villages without oil palm development. However, we found the opposite for plantations developed in remote villages with higher forest cover, in which the majority of communities previously relied on subsistence-based livelihoods. Overall, oil palm growing villages were more associated with reduced rate of improvement of social and environmental well-being compared to villages without oil palm development, regardless of location and baseline community livelihoods. Our findings highlight an urgent need for careful evaluation and planning in the development of oil palm agriculture in remote forested areas. For oil palm regions that have been developed, our study shows that unsustainable livelihoods, increased socioeconomic disparity, and environmental issues remain major challenges

Changing landscapes, livelihoods and village welfare in the context of oil palm development

The United Nations’ Sustainable Development Goals underscore the need for improved understanding of relationships between changes in landscapes, livelihoods, and social welfare, and how these relate to tackling poverty, inequality, and environmental degradation. Such assessments are especially relevant in the context of oil palm agricultural expansion, which has rapidly replaced traditional livelihoods and generates ongoing political debates around the world. Proponents of the oil palm industry have used economic objectives to justify expansion, while opponents have raised the negative socioecological impacts on communities. To assist the debate, we assessed the association between the change in land-uses and climate, the change in village primary livelihoods towards monocultural oil palm cultivation, and the change in village welfare after adopting oil palm across Kalimantan, Indonesian Borneo, between 2000 and 2014. We show that the change in village primary livelihoods towards monocultural oil palm cultivation during this period was associated with complex interrelations between the expansion of agricultural industries, and conducive climate and market conditions for supporting agricultural production. The shift to oil palm monoculture brought significant economic benefit to villages, but this was limited to those with past exposure to plantation management and the market economy, such as in polyculture plantation villages. For villages where the majority of communities practiced traditional subsistence-based livelihoods (farming, foraging and fishing), the economic benefit from a shift to oil palm lasted only a few years after transition, while the socioecological welfare deteriorated. Furthermore, the shift to oil palm monoculture jeopardized food security among these subsistence livelihood villages. Baseline economic and socioecological conditions of villages, therefore, critically determine the success of the oil palm sector in providing economic benefits over the long term. Our study urgently calls for considering oil palm development objectives not only in terms of regional economic gain, but also the future maintenance of socioecological welfare of village communities

Replanting unproductive palm oil with smallholder plantations can help achieve Sustainable Development Goals in Sumatra, Indonesia

Oil palm (Elaeis guinensis) is a controversial crop. To assess its sustainability, we analysed the contribution of different types of plantations (smallholder, industrial and unproductive) towards meeting six Sustainable Development Goals. Using spatial econometric methods and data from 25,067 villages in Sumatra, Indonesia, we revealed that unproductive plantations are associated with more cases of malnutrition, worsened school access, more air pollution and increased criminality. We also proposed a strategy for sustainable palm oil expansion based on replanting unproductive plantations with either industrial or smallholder palm oil. Smallholder replanting was beneficial for five Goals (Zero poverty, Good health, Quality Education, Environmental preservation and Crime reduction), while the same intervention only improved two Goals in the industrial case (Zero poverty and Quality Education). Our appraisal is relevant to policymakers aiming towards the 2030 Agenda, organisations planning oil palm expansion, and retailers or consumers concerned about the sustainability of oil consumption

Analyzing procedural equity in government-led community-based forest management

Participatory approaches to forest management have been promoted as a means of returning rights historically removed, and as a way of managing natural resources sustainably, fairly, and to improve livelihoods in communities. Top-down models of community-based forest management take the perspective that if people feel ownership over, have a voice in decisions about, and can benefit from surrounding ecosystems, then they will be motivated to maintain and protect them. However, even participatory approaches, such as community-based forest management, may not always result in clear positive outcomes for involvement in decision making and forest conservation. We examine whether an Indonesian government initiative for community-based forest management was positively associated with community members' participation in local decision making and support for conservation and sustainable management of forest resources, in the context of state-owned lands. We used household questionnaire data to compare villages with and without a community forest, and community forests over time in a case study region of West Kalimantan. Analyzing forest visitations, conservation support, and indicators of procedural equity, we found no consistent association between having a community forest and higher levels of participation in decision making or household support for forest conservation. However, well-being indicators were positively associated with more active participation. The level of support for forest conservation was also positively related to households' leadership in village institutions and higher levels of well-being, particularly subjective well-being, land tenure, and material wealth. These social-demographic factors are important considerations when designing and implementing community-based forest management, which strives for fair and just decision-making processes along with forest conservation. The findings highlight how existing socioeconomic contexts factor into local institutions, and that accounting for these in program design and implementation may help address existing social inequalities that influence achieving joint social and ecological objectives
