River fisheries are extremely important for food-security among the rural poor in many tropical countries. The growing populations and rapid industrialisation of these countries require that appropriate action should be taken to sustain the resources for future generations. However, an incomplete understanding of river fisheries biology, at the managerial level, often hampers proper planning and management. This is partly due to the difficult access to large parts of such river basins, the complex nature of the fisheries, and in many cases a severe lack of research funds. In contrast, the thousands, or often millions of people who live along the shores of the rivers and rely on the fishery for their daily survival, have a very intimate knowledge of the behaviour and biology of the fish. In this situation, gathering the knowledge of the fishers may provide politicians or planners with baseline knowledge in a relatively quick and cheap way.This paper discusses two years of research using local knowledge in the study of fish migration and spawning in the Lower Mekong Basin. The study involves semi-structured interviews with 355 expert fishermen in four countries along 2,400 km of the Mekong mainstream. By piecing together information from fishermen in different areas, we were able to construct migration maps, and provide rough estimates of the spawning period for 50 fish species. We conclude that river fisheries research can benefit significantly from local knowledge as the basis for future research.  相似文献

The need for environmental and urban planning reached a critical point in the year 2007, when one-half of the world's population could be defined as living in cities. Urbanisation in India is also increasing at a fast rate. Urban chaos in India, emanating from the continuous ignorance of fragile ecosystems, calls for the reshaping of existing cities as ‘eco-cities’. The ‘eco-city’—a well-known concept in the western world—is new to the Indian context. While western connotations of eco-cities should not be discarded outright in the context of India, core concerns vary significantly for obvious reasons. Recognising two facts—firstly, eco-city development is altogether a fresh approach to human settlement development in India, and, secondly, the manifold increase in the vulnerability of cities—this paper discusses documented good practice, reinforcing evolution towards the eco-city vision. Lessons drawn from the examples cited are further deconstructed in the light of their contribution to urban risk reduction, which provides direction to appreciating the ‘disaster-resilient eco-community’ concept in Puri, a coastal city in India. Further, this paper attempts to unravel existing community-based practices in Puri, which are boon to the local environment and invariably reduce disaster risk. These seemingly modest neighbourhood initiatives symbolise immense societal wealth, which can be calibrated appropriately for reducing urban environmental risk as well. This paper also illustrates how a ‘disaster resilient eco-community’ approach is inevitable in the present and future contexts not only to preserve sustainable development gains but also to secure human well-being.  相似文献

Abstract: Researchers and conservation managers largely agree on the relevance of traditional ecological knowledge for natural resource management in indigenous communities, but its prevalence and role as societies modernize are contested. We analyzed the transmission of traditional knowledge among rural local people in communities linked to protected areas in Doñana, southwestern Spain. We studied changes in knowledge related to local practices in agriculture and livestock farming among 198 informants from three generations that cover the period in which the area transited from an economy strongly dependent on local ecosystem services to a market economy with intensified production systems. Our results suggest an abrupt loss of traditional agricultural knowledge related to rapid transformations and intensification of agricultural systems, but maintenance of knowledge of traditional livestock farming, an activity allowed in the protected areas that maintains strong links with local cultural identity. Our results demonstrate the potential of protected areas in protecting remaining bodies of traditional ecological knowledge in developed country settings. Nevertheless, we note that strict protection in cultural‐landscape‐dominated areas can disrupt transmission of traditional knowledge if local resource users and related practices are excluded from ecosystem management.  相似文献

ABSTRACT

Quests for devolving more power to local actors for nature protection stem from both international and national policies. Also, there is a growing recognition of the need for local governments to promote green infrastructure for citizens to recreate and learn about their environment. Starting in 2004, the Swedish government has allocated special funding towards these goals through the Local Nature Conservation Programme (LONA). Virtually all Swedish municipalities have received such funding in pursuit of facilitating wide access to nature and promoting recreational activities, including the protection of nature areas, creating pathways, information devices, and promoting these areas among new societal groups to enjoy. This study presents the results of ten years of experience with LONA. A survey with respondents from 191 municipalities and 20 county administrations, together with 20 key informant interviews, show that the programme has been a success in several respects. Not only have most municipalities created a wealth of new ways to engage local organisations and citizens in nature conservation and recreation, but they have also broadened the ways they think about how nature is important to their constituencies. Due to innovative ways to count voluntary work as local matching of funding, smaller and less resourceful municipalities have also become engaged. Still, the local needs for further initiatives are deemed considerable. State support coupled with knowledge sharing is important to show policy priority to such bottom-up initiatives.  相似文献

Community knowledge exchanges have played a key role in developmental processes in the Suid Bokkeveld community of South Africa. Two exchange visits were undertaken with the support of the Department of Agriculture and an NGO, the Environmental Monitoring Group, which have led to local economic development and enhanced capacity to manage natural resources in a sustainable manner. These pilot projects were undertaken within the framework of the Community Exchange and Training Programme of the Global Mechanism of the United Nations Convention to Combat Desertification (UNCCD). The methodology applied included facilitation to develop a community-based vision for development, in terms of which the community exchange process was designed. A Facilitation Team of service providers conducted preparatory workshops, and identified potential partner communities. Two exchange visits were carried out, one focused on Rooibos production and marketing, and the other on community-based eco-tourism. Following report-back and planning workshops, emerging community-driven initiatives were supported through their formative stages. The initiatives have not only resulted in enhanced livelihoods, but the methodology has also been applied widely in a number of different contexts.  相似文献

Combating desertification requires the involvement of many people ranging from communities who experience the effects on a daily basis and scientists attempting to understand the biophysical and socio-economic causes and consequences of desertification, to developers and policy makers on all levels. In many instances, however, the understanding, approaches and actions of these different groups contradict rather than support one another. Over the period 2000 to 2002, a conference process undertaken in southern Africa brought together communities, scientists, and development workers to test the concept that they could connect and work together to combat desertification, given an appropriate framework. The conference was a success, and communities, scientists and developers did exchange experience, knowledge and information. Many lessons were learned, although some pitfalls were experienced. Time, funding, enhanced communication, and good will are the primary ingredients for ensuring that different sectors complement one another in their efforts to combat desertification.  相似文献
