Agriculture and biodiversity have often been regarded as separate concerns. Although biodiversity underpins much of modern agriculture, the development of contemporary production systems has resulted in extensive land conversion and concomitant biodiversity loss. In order to feed an ever growing population, innovative and acceptable ways of integrating biodiversity conservation and food production need to be identified. Maintaining diversity within agricultural systems is not a novel approach but one practiced by many smallholder farmers globally, in many different ways. The nutritional and livelihood benefits of diverse production systems are one way of achieving food security. Such systems are also more resilient to climate induced events or other shocks. Forests represent an important repository of food and other resources that can play a key role in contributing towards food security, especially if integrated into complex systems that are managed for multiple benefits.

In order to further understanding of the links between biological and cultural diversity, this study examined the role of forest species and biodiversity in the livelihoods of indigenous Bakweri villagers and migrants to the Mount Cameroon region. Surveys of resources consumed and sold by 118 households were undertaken in five villages over the course of one year. The contributions of different habitats and management systems (compounds, farms, fallow, forest) and species (native and introduced; cultivated and wild-harvested) to local livelihoods were evaluated. The study showed that indigenous households depend to a much greater extent upon a range of habitats and species than migrant households, particularly for subsistence. Indigenous resource management systems grow from historical relationships between people and place, and promote resilience, well-being and adaptation in an area long characterized by environmental, social, political, and economic uncertainty. The managed landscapes of indigenous villages can contribute to broader conservation efforts in the region, including those associated with the newly established Mount Cameroon National Park.

Throughout history, forests dwellers have adapted to permanent changes of forest ecosystems that, in essence, are dynamic. Accordingly, they have long served as models of how humans lived when their lifestyles and genetic endowment were complementary. What is now commonly described as the “paleodiet” tends to be put forward as a benchmark for present-day efforts to promote health and prevent nutritional diseases, even in industrialized countries. Although forest ecosystems provide food and medicines to forest dwellers, over the last half-century these ecosystems have undergone unprecedented pressure to make way for economic growth and industrialization, often at the cost of ecological functions that may affect human health, both in short term (i.e. increase in infectious diseases) and long term (incidence of global change). As radical alterations occur such as deforestation, modification of resource availability, and the penetration of cash economies, forest dwellers encounter increasing difficulties in accommodating their socioeconomic, cultural, and political systems, thus impeding their ecological success. Diets and diseases are sensitive indicators of the ecological and cultural costs that former hunter-gatherers currently pay to achieve their share of modernity. This paper exposes the nutritional and epidemiological consequences of the maladaptation of former hunter-gatherers in relation to their recent sedentarization. It is primarily based on case studies carried out among the Baka and Kola Pygmies of Cameroon, and the Tubu Punan of Borneo.

Food insecurity and malnutrition in local populations both result from and drive deforestation. This paper examines the relationships between diet of local people and measures of forest cover and use in the East Usambara Mountains, Tanzania. Data on dietary diversity and intake were collected for 270 children and their mothers. Area of tree cover within the vicinity of each household was examined in relation to forest use and diet. Individuals using foods from forest and other non-farm land had higher dietary diversity, consumed more animal source foods and had more nutrient dense diets. They also had more tree cover in a close proximity to the home, suggesting a relationship between tree cover and forest food use. Households reporting trips to the forest had lower area of tree cover within close proximity, suggesting that land close to the home with tree cover such as agroforest and fallow is important for obtaining subsistence products. Although historically there has been little motivation for local people to participate in forest conservation in the East Usambaras, the maintenance of tree cover in the landscape around the home, especially on agricultural and village land, may be important in ensuring continued access to the health benefits potentially available in wild and forest foods.

The impacts of Payments for Environmental Services (PES) and creation of formal Voluntary Conserved Areas (VCAs) on local diets, agricultural practices, subsistence hunting and livelihoods, were assessed in a Chinantec community of southern Mexico. The community has set aside VCAs covering 4 300 ha of its 5 928 ha of communal lands and forests, and has received over S769 245 in PES for protection of 2 822 ha of watersheds roughly overlapping the VCAs. Community members attribute decreased maize and other subsistence crop yields, reduction of area available for agriculture, and shortened fallow cycles to the new conservation policies. Meat consumption has decreased after a hunting ban, accompanied by increases in purchasing meat still consumed. By agreeing to conservation measures that restrict their use of ancestral agricultural land and prohibit hunting, villagers have seen local food security become less stable, leading to greater dependency on external food supplies. Continued strict preservation measures under the guise of community conservation could lead to losses of agrobiodiversity, dietary diversity, hunting skills and associated environmental knowledge. Appropriate application of the precautionary principle is essential to avoid structural displacement of local peoples and to ensure the success of community conservation initiatives.

The cultivation of indigenous and exotic fruits for sub-Saharan Africa's domestic markets can bring increased revenues for smallholders and improve the diets of local consumers. There are, however, many bottlenecks which need to be addressed so that wider benefits from such activities are realised. Here, we describe key interventions being taken to address current constraints. For indigenous fruit trees, it is necessary to set priorities for which species to promote and to engage in participatory domestication for the improvement of yield, quality and germplasm delivery to farmers. For exotic fruits, ‘south-south’ transfer of advanced cultivars and the development of small-scale commercial suppliers of planting material are required to reinvigorate production. For both indigenous and exotic species, a focus on improving market value chains to bring greater benefits to producers is needed. We describe where further work is required to increase efficiency in the sector and to favour smallholder involvement.

Protein from forest wildlife is crucial to rural food security and livelihoods across the tropics. The harvest of animals such as tapir, duikers, deer, pigs, peccaries, primates and larger rodents, birds and reptiles provides benefits to local people worth millions of USS annually and represents around 6 million tonnes of animals extracted yearly. Vulnerability to hunting varies, with some species sustaining populations in heavily hunted secondary habitats, while others require intact forests with minimal harvesting to maintain healthy populations. Some species or groups have been characterized as ecosystem engineers and ecological keystone species. They affect plant distribution and structure ecosystems, through seed dispersal and predation, grazing, browsing, rooting and other mechanisms. Global attention has been drawn to their loss through debates regarding bushmeat, the “empty forest” syndrome and their ecological importance. However, information on the harvest remains fragmentary, along with understanding of ecological, socioeconomic and cultural dimensions. Here we assess the consequences, both for ecosystems and local livelihoods, of the loss of these species in the Amazon and Congo basins.

Health issues of forest women in developing countries merit more serious attention. This paper reviews existing literature on the interface of women, health and forests to highlight conservation opportunities and challenges. Most women in forests are collectors and users of forest species. However, existing conservation efforts, deforestation, poor health services and household responsibilities can intensify health and safety concerns for forest dependent women. Women are likely to bear the strenuous burden of carrying fuelwood (and other forest products) long distances and inhaling smoke while cooking. The burden of unintended childbearing, diseases and cultural issues can compound their health problems. To improve local livelihoods and environments, some organisations have initiated activities that integrate conservation and human health objectives, including family planning. This article provides project examples, where the involvement of women has been identified as a key component in effectively meeting both conservation and development goals.
