ABSTRACT

The multibillion-dollar trade in bushmeat is among the most immediate threats to the persistence of tropical vertebrates,
but our understanding of its underlying drivers and effects on human welfare is limited by a lack of empirical data. We used
30 years of data from Ghana to link mammal declines to the bushmeat trade and to spatial and temporal changes in the availability
of fish. We show that years of poor fish supply coincided with increased hunting in nature reserves and sharp declines in
biomass of 41 wildlife species. Local market data provide evidence of a direct link between fish supply and subsequent bushmeat
demand in villages and show bushmeat's role as a dietary staple in the region. Our results emphasize the urgent need to develop
cheap protein alternatives to bushmeat and to improve fisheries management by foreign and domestic fleets to avert extinctions
of tropical wildlife.

    • "For instance, the decline of large mammal populations is higher in West African protected areas than in protected areas from other African regions (Craigie et al., 2010). The great conservation challenges faced by West African species are most likely a consequence of various causes acting at various scales, including the lack of financial and personnel resources in protected areas combined with intense hunting for bushmeat consumption (Brashares et al., 2004) and habitat destruction. For example , the West African red colobus, Procolobus badius waldroni, was the first primate to be declared extinct in the 20th century (Oates et al., 2000). "

    ABSTRACT: The ability of forest-dwelling species to adapt to changes in their habitat is being increasingly challenged by the rapid pace of human-induced forest degradation. Understanding the effect of such environmental changes on biodiversity requires comparative analyses across species living within the same habitats. We investigated the effect of forest exploitation on the genetic structure and demography of two sympatric arboreal primates showing differences in their socioecology: the Western black-and-white colobus (Colobus polykomos) and Temminck's red colobus (Procolobus badius temminckii). We conducted the study in a fragmented and human-impacted forest in Guinea Bissau. Using microsatellite data from six C. polykomos and eight P. b. temminckii social groups, we found that in C. polykomos the distribution of genetic diversity followed an isolation-by-distance pattern whereas for P. b. temminckii, the results suggested restriction in female dispersal. We detected a strong, recent bottleneck for both primates, which we inferred to have resulted from the anthropogenic exploitation of forest resources in the last centuries. The bottleneck signal was stronger for P. b. temminckii as a likely consequence of its larger estimated ancestral population size. Finally, we discussed the different analytical approaches used. Our results confirm that P. b. temminckii is more affected by habitat changes than C. polykomos, despite being phylogenetically close. Nonetheless, the low estimated effective population sizes and the known demographic changes indicate that both species are severely threatened by human forest exploitation, requiring urgent conservation action.

Numerous studies have used HH surveys to determine the important of forest products to rural communities (Falconer, 1994; Townson, 1995; Van Dijk, 1999; Ambrose-Oji, 2003; Brashares et al., 2004; East et al., 2005; Degrande et al., 2006).

    ABSTRACT: Short title: Options and strategies for livelihood sustainability This paper examines the options and strategies for livelihood sustainability in mountainous region. Three villages of the upper Minjiang River basin, Sichuan province, China, were studied based on their altitudes and distances from the road. These villages are characterized by high landscape vulnerability and fragility, as this area is prone to severe natural hazards mainly flash floods and earthquakes. Sustainable livelihoods approach was applied and a household level survey was carried out to gather data on livelihood capitals such as natural, human, financial, physical and social. The ecological services are abundant in the form of water and forest resources and agro-ecological conditions provide a suitable base for horticultural farming, which is already in practice. Farming land is limited and cultivation is carried out mainly on the terraced fields. Suitability in the climatic conditions further enhances the scope for tourism development. Economic and social factors vary with altitudes and distance from the urban centres. Community participation and institutional support in the developmental processes is remarkable in all three locations. This study reveals that the future sustainability of livelihoods is dependent on all above-mentioned capitals, particularly on the optimal use of natural resources, horticultural farming and tourism.

    • "This is the result of a high fish demand, and the combination of a stable political environment and its commissioning of the only commercial fish feed mill in West Africa (Ainoo-Ansah, 2013; Frimpong et al., 2014). The country derives a majority of its dietary protein from fish (Brashares et al., 2004), with an estimated per capita fish consumption of 20–30 kg per annum in 2009 (Food and Agriculture Organization, 2012). This is higher than the global estimate of about 18 kg (Food and Agriculture Organization, 2012). "

    ABSTRACT: Best management practices (BMPs) are the most cost-effective means of mitigating negative impacts of pond aquaculture on the environment. The impacts of BMPs and other innovations on fish farm profits have been studied widely. This study estimates impacts of BMP adoption on social welfare. We employed the economic surplus model to determine net present value (NPV) of adopting the more expensive but less polluting commercial floating fish feed in the pond culture of Nile tilapia (Oreochromis niloticus) in Ghana. We also conducted a sensitivity analysis to determine which variables had the greatest influence on mean NPV. Our results indicate an NPV of US$ 11 million from the adoption of commercial floating feed in pond farming alone in Ghana. The variables with the biggest impacts on NPV were level of change in tilapia yield, and level of change in production costs, with the adoption of the new feed type. We conclude that adoption of yield-enhancing BMPs and innovations in Ghana will result in significant social welfare benefits. We recommend that credit programs and other financial packages be set up by governments or nongovernmental organizations to help farmers meet the increased cost of fish feed and to accelerate diffusion of commercial fish feed in pond farming.
