The social sciences are often seen as being in opposition to conservation and the practice of conservationists. Yet social scientists have made important contributions to conservation and could make even more contributions if they are willing to use their perceptive, insightful tools as a means of both improving the practice of conservation and sharpening social science’s critique of conservation ideas and practices. I provide two lists: first, a list of the ways in which I think social science work has already improved conservation practice and, second, a set of generalizations made by some social scientists about the practice of conservation that are incorrect or incomplete. I argue that a more careful application of social science tools and approaches could begin an active and informed exploration of the diversity of values, histories, institutions, politics and approaches in conservation. This would facilitate the sharpening of social science’s critique of conservation ideas and practices and, through these, improve the practice of conservation.

The IUCN protected area management category system provides an internationally-recognized, unifying framework for the description and classification of the world’s diverse protected areas. It includes six main categories, of which category V has attracted debate because of its emphasis on the role of harmonious people–nature interactions in maintaining biodiversity within cultural landscapes. Madagascar’s new generation of protected areas comprises sites mainly proposed as category V, with the joint management objectives of biodiversity conservation and the promotion of natural resource use for rural development. Here, I use a categorization decision tool to investigate the categorization of 10 new protected areas proposed as category V, and find that these sites fail to meet the criteria for any management category. I argue that category V is inappropriate for these new protected areas because their associated people–nature interactions are largely negative for biodiversity. I further argue that management of these new protected areas differs fundamentally from management of category V protected areas in Europe, and recommend the modification of the management category system to account for such distinctions.

Understanding the role that protected areas play in the livelihood security of local communities is essential to ensure that local people are not left shouldering the costs of what is a public good, and to help maintain robust local and national constituencies for biodiversity conservation. To provide baseline data for a longitudinal study on the effects of newly established national parks on human livelihoods in Gabon we conducted a cross-sectional study that compared livelihood indicators between communities that do, and do not, use natural resources within protected areas. We interviewed 2,035 households in 117 villages at four sites, recording income, consumption, education, health indicators and social capital, and village characteristics such as distance to markets, distance to park boundaries, and land cover within a 5-km radius. Our results indicated that closed rainforest coverage was greater around park than control villages and that this difference was associated with a greater reliance of park households on forest resources. However, we found no systematic differences in most livelihood measures between park and control households. Instead, the relationship between household livelihood measures and proximity to parks varied in idiosyncratic ways between sites, suggesting that determinants of human welfare are highly localized and cannot be generalized to larger spatial scales.

Spatial prioritizations and gap analyses are increasingly undertaken to allocate conservation resources. Most spatial prioritizations are conducted without specifying the conservation instruments to be implemented and gap analyses typically assess formally protected areas but increasingly include private land conservation instruments. We examine conservancies to see if these voluntary instruments contribute towards achieving goals of South African conservation planning initiatives. We conducted a nationwide survey and interviews with conservancy members in Gauteng and the Eastern Cape. Conservancies have potential for assisting South Africa to achieve conservation planning goals at national and local scales but their inclusion in spatial prioritizations and gap analyses predicates improved protection for nature, operational refinement and increased support. We sound a warning to conservation planning initiatives that incorporate voluntary instruments on private land, and present recommendations for strengthening such instruments to make them more effective. Our findings may assist conservation planners elsewhere to design more effective conservation planning initiatives focused on private land.

Approaches to community-based natural resource management tend to vary among programmes based on the needs and characteristics of the communities in which the programmes operate. Variation also exists within individual programmes, creating the potential for conflict if management does not recognize that these differences can indicate competing interests and needs. In this study we examine livelihood activities at the household level in a wildlife conservancy along the Kwando River in the Caprivi region of Namibia. We ask how people in the conservancy make their livelihoods and what differences exist between the conservancy’s riverside and inland populations. The study finds that the inland population, c. 20 km from the river on slightly heavier soils, engages in fewer livelihood activities and has greater food security than does the riverside population. We further establish that differences between the two populations are significant enough to indicate two distinct combinations of livelihood activities with different environmental interactions. These findings suggest that any management action taken by the conservancy will affect household livelihoods differently based on location and that these differences must be considered if the conservancy is to make a successful transition from a subsistence-based agricultural system to a wildlife-based economy.

Private nature reserves created by non-governmental organizations (NGOs) are increasing, and their growing number and extent means that they can potentially contribute to biodiversity goals at a global scale. However, the success of these reserves depends on the legal, economic and institutional conditions framing their creation and management. We explored these conditions, and the opportunities and challenges facing conservation organizations in managing private nature reserves, across several countries, with an emphasis on Australia. Results from 17 semi-structured interviews with representatives of private conservation organizations indicated that while private reserves may enhance the conservation estate, challenges remain. Legal frameworks, especially tenure and economic laws, vary across and within countries, presenting conservation organizations with significant opportunities or constraints to owning and/or managing private nature reserves. Many acquired land without strategic acquisition procedures and secured funding for property acquisition but not management, affecting the long-term maintenance of properties. Other typical problems were tied to the institutional capacity of the organizations. Greater planning within organizations, especially financial planning, is required and NGOs must understand opportunities and constraints present in legislative frameworks at the outset. Organizations must establish their expertise gaps and address them. To this end, partnerships between organizations and/or with government can prove critical.

Building local civil society constituencies for conservation is a particularly high priority in Indochina given the regional prevalence of weak and highly-centralized government institutions with an inability or lack of will to enforce protection on the ground. BirdLife International has developed and piloted a small-scale, community-based Local Conservation Group approach to site-based conservation globally. In Indochina a number of important lessons have been learned, particularly related to the need for participatory project and activity planning, increased attention to provision of tangible benefits that clearly meet both conservation and development objectives and are tailored to heterogeneous communities, increased support for awareness-raising activities, clear monitoring of activities and impacts, and truly committed partner support for implementation.

This study was based on interviews with 388 randomly selected households living near four protected areas in northern and south-eastern Bangladesh: Chunati Wildlife Sanctuary, Teknaf Game Reserve and two forest reserves. The respondents were generally poor and their perception of conservation varied across the study areas. Respondents were generally reluctant to embrace conservation and their attitude towards the conservation of protected areas depended on a set of demographic and socio-economic factors. People in northern Bangladesh had somewhat more positive attitudes towards conservation than those in the south-east. The two most important variables explaining respondents’ attitudes towards conservation were the distance they lived from protected areas and their monthly income. People who are poor and who live closer to the protected areas disliked the conservation measures most.

The Socotra archipelago, Yemen, in the north-west Indian Ocean, has outstanding endemic biodiversity, and was listed as a World Heritage Site in 2008. Although inhabited for 6 millennia Socotra only began to open up to the outside world in 1990. With conservation interventions starting prior to major developments, and building on centuries-old low-intensity resource management, Socotra has been in a unique position to practice pre-emptive conservation. In 1997 modern conservation started with biodiversity and socio-economic surveys, with inputs from communities and decision makers, which fed into the Conservation Zoning Plan. Approved in 2000, this has been the archipelago’s principal conservation planning and management tool. Regulations and bans on fishing practices, the collection of coral stones and export of biological materials have all been relatively well complied with by local communities and authorities. Inappropriate road construction, however, driven by non-islanders, has demonstrated the limits of the Conservation Zoning Plan, highlighting significant institutional challenges in planning and coordination. The capacity of the Socotra-based conservation institution has increased dramatically over the last decade. Its personnel are generally respected, largely because their roles include assisting local communities with development initiatives, underlining the importance of integrating conservation and development at the onset of conservation. Although the integrity of the landscape will inevitably decline, especially along the northern coastline, Socotri conservationists, backed by international support, are in a unique position to shape the archipelago’s future.

The target adopted by world leaders of significantly reducing the rate of biodiversity loss by 2010 was not met but this stimulated a new suite of biodiversity targets for 2020 adopted by the Parties to the Convention on Biological Diversity (CBD) in October 2010. Indicators will be essential for monitoring progress towards these targets and the CBD will be defining a suite of relevant indicators, building on those developed for the 2010 target. Here we argue that explicitly linked sets of indicators offer a more useful framework than do individual indicators because the former are easier to understand, communicate and interpret to guide policy. A Response-Pressure-State-Benefit framework for structuring and linking indicators facilitates an understanding of the relationships between policy actions, anthropogenic threats, the status of biodiversity and the benefits that people derive from it. Such an approach is appropriate at global, regional, national and local scales but for many systems it is easier to demonstrate causal linkages and use them to aid decision making at national and local scales. We outline examples of linked indicator sets for humid tropical forests and marine fisheries as illustrations of the concept and conclude that much work remains to be done in developing both the indicators and the causal links between them.

Use of the veterinary drug diclofenac is responsible for bringing three species of Gyps vultures endemic to South Asia to the brink of extinction, and the Government of India banned veterinary use of the drug in May 2006. To evaluate the effectiveness of the ban we undertook surveys of > 250 veterinary and general pharmacies in 11 Indian states from November 2007 to June 2010. Twelve different classes of non-steroidal anti-inflammatory drugs (NSAIDs) were purchased from 176 pharmacies. Other than meloxicam (of negligible toxicity to vultures at likely concentrations in their food), diclofenac and ketoprofen (both toxic to vultures), little is known of the safety or toxicity of the remaining nine NSAIDs on sale. Meloxicam was the most commonly encountered drug, sold in 70% of pharmacies, but 50% of the meloxicam brands sold had paracetamol (acetaminophen) as a second ingredient. Diclofenac and ketoprofen were recorded in 36 and 29% of pharmacies, respectively, with states in western and central India having the highest prevalence of diclofenac (44–45%). Although the large number of manufacturers and availability of meloxicam is encouraging, the wide range of untested NSAIDs and continued availability of diclofenac is a major source of concern. Circumvention of the 2006 diclofenac ban is being achieved by illegally selling forms of diclofenac manufactured for human use for veterinary purposes. To provide a safer environment for vultures in South Asia we recommend reducing the size of vials of diclofenac meant for human use, to increase the costs of illegal veterinary use, and taking action against pharmaceutical manufacturers and pharmacies flouting the diclofenac ban.

We conducted a primate survey in Samkos Wildlife Sanctuary, western Cambodia, during the wet season in 2009. We visually confirmed the presence of five out of six primate species thought to occur in the area: Bengal slow loris Nycticebus bengalensis, Indochinese silvered langur Trachypithecus germaini, pileated gibbon Hylobates pileatus, pig-tailed macaque Macaca leonina and long-tailed macaque Macaca fascicularis. We did not find any sign of the stump-tailed macaque Macaca arctoides and suggest it is absent in Samkos Wildlife Sanctuary and possibly from the Cardamom Mountains. We provide the abundance measures for each primate species; the three most abundant species were Bengal slow loris, Indochinese silvered langur and pileated gibbon. We propose Samkos Wildlife Sanctuary as a priority for primate conservation in Cambodia.

The elusive, Vulnerable owl-faced monkey Cercopithecus hamlyni is a rare and little studied species and one of the least known of the African Cercopithecidae. This study describes the distribution and relative abundance of the only known population in East Africa, in Nyungwe National Park, Rwanda. This species is restricted to a small (32 km2) area of bamboo and bamboo–forest mix in the southern sector of the Park, close to the international border with Burundi. We present the first empirical data of its abundance in the bamboo forests of Nyungwe. A total length of 185 km of transect were surveyed to estimate relative abundance of diurnal primates. Encounter rates with the owl-faced monkey were 0.081 groups km-1 (n = 15). Mean group size was 3.6 individuals. Eight independent photographs of C. hamlyni were obtained from five camera traps during 182 camera-days. Four other species of primates occur in the bamboo forest: eastern chimpanzee Pan troglodytes schweinfurthii, Angola colobus Colobus angolensis, L’Hoest’s monkey Cercopithecus l’hoesti and blue monkey Cercopithecus mitis. The main threats to the bamboo forest are from the illegal harvesting of bamboo, trapping and tree-cutting. These threats originate from both Rwanda and Burundi. There is an urgent need for conservation action to halt the destruction and degradation of the bamboo forest and to ensure the long-term survival of the owl-faced monkey in Rwanda.

The blond titi monkey Callicebus barbarabrownae lives in forest fragments in the caatinga (tropical thorn scrub and forest) of north-east Brazil. In 2004–2005 we carried out five surveys to determine its current distribution and conservation status; surveying forest fragments, interviewing local people, and recording vegetation types and patterns of land use. The blond titi monkey occurs mainly in Dense Arboreal Caatinga and Highland Coastal Rainforest in the state of Bahia, at elevations of 241–908 m. Its range extends over 291,438 km2, with an area of occupancy of 2,636 km2. Estimated minimum population was 260 individuals. It was not recorded in any protected area. Cattle ranching favours the persistence of forest fragments for this species, whereas agriculture, subsistence or commercial, does not. Our findings supported the IUCN Red List assessment of Critically Endangered for this species.
