The aim of this study is to characterise the human-wildlife conflicts that occur around the KBNP, especially with regard to primates. Surveys were carried out in 260 households selected using the snowball method. The results showed that human-wildlife conflicts around the KBNP are characterised by the destruction of crops in riparian fields by monkeys, chimpanzees and gorillas, the destruction of houses, physical attacks and zoonoses. Despite the conservation and protection measures for wildlife and local populations put in place by the Park’s managers, conflicts between local populations and the Park’s wild animals are still visible. These conflicts lead to the detention of wild animals by local people roaming in the villages and to poaching on the Park’s boundaries. The weakness of the community management policy on the part of the park managers and the resentment of the indigenous peoples towards the restriction of their access to natural resources are the major constraints on the sustainable management of conflicts between the local populations and the wild animals in the KBNP. The strategies for the sustainable resolution of human-wildlife conflicts around the KBNP must be geared towards and integrated into a community conservation approach.展开更多

Most forest areas in Mexico are owned by local communities either through the ejido, agrarian indigenous community or groups of small owners. In the last 30 years, many forest communities explored forest production at a commercial scale, creating their own communal forestry business and concurring to national markets with their timber and non-timber products. The socio-economical impacts of this approach were tremendous, steadily improving communities living standards. This success prompted rural organizations to ask the Mexican government to launch programs to expand the "community forestry" model. With international assistance from the World Bank and other agencies, the government of Mexico launched three different programs to foster forest commons: the Forest Conservation and Management Program, the Indigenous, Communities and Biodiversity Project and the Mexican part of the Mesoamerican Biological Corridor. Performance of these programs has been assessed through the World Bank evaluation framework, but the question about their environmental impact or even about their environmental sustainability and therefore their validity as national policies has been scantily explored and practically not debated. To contribute to answering these questions, the author made an extensive analysis of their impact over forest cover during the 2003-2008 period using land cover maps and correlated them with institutional development variables, building a social organization and collective action index (SOCAI), following Elinor Ostrom institutional analysis and development framework (lAD).展开更多

In the present scenario, environmental writing becomes a social discourse. This is the result of a new, vibrant and growing environmental constituency in societies such as Brazil, India, Thailand and other Third World Countries. The features of environmental writing include a visible concern for social justice, defence of livelihood and the determining part played by women. This new discourse has emerged with a new focus on redefinition of terms like human rights, common good, democracy and CPRs (common property resources). Environmental Writing becomes a powerful discourse when it protests against the increasingly intrusive and interventionist developmental projects, implemented by the government, which in turn assert dominion over indigenous people of the land. There is also a strong emphasis on prudence among the poor as contrasted to the ecological profligacy of the rich. This paper is an attempt to examine the voices of dissent and the accountability of postmodern writers and environmental activists in India regarding environmental issues in India.展开更多

Community conservancy, a powerful extension of the PA system, has great potential to support biodiversity conservation, poverty eradication and conflict mitigation. Based on its policy environment and development characteristics, Kenya has implemented community conservation practices, and established over 160 conservancies across the country in the past decades. This paper reviews the development and experiences of community conservancies, discusses how they have been implemented in Kenya, and looks at the management paradigm, efficacy and challenges to help better understand the community conservancy approach. The development trajectory and lessons these conservancies have to offer can contribute to the sustainable utilization of natural resources and the enhancement of community wellbeing in Kenya and other countries alike.展开更多
