| We study the management of a natural resource that supports ecosystems as well as human needs. The reduction in the resource base poses a threat of occurrence of catastrophic ecological events, such as the sudden collapse of the natural habitat, that lead to severe loss of biodiversity. The event occurrence conditions involve uncertainty of various types, and the distinction among these types affects the optimal exploitation policies. When uncertainty is due to our ignorance of some aspects of the underlying ecology, the isolated equilibrium states characterizing optimal exploitation for many renewable resource problems become equilibrium intervals, giving rise to hysteresis phenomena. Events triggered by genuinely stochastic environmental conditions... |

| This report reviews the spiny lobster fishery on the Mahe Plateau during the 1995-1996 fishing season. Following recommendation made after the 1994-1995 season the lobster fishing season was again re-opened for the fourth consecutive year. As in the 1994-1995 fishing season the 1995-1996 season was opened over a three months period. The monitoring programme set up in 1992 was continued to gather more information on the spiny lobster stock so as to improve the management of this resource around the Mahe Plateau. A total of 26 applications were made for licenses to fish for lobster, however, only 23 applicants were granted licenses after paying the required license fee. 17 licenses were bought by fishermen from Mahe, 4 by fishermen from La Digue and 2 by... |

| This report reviews the spiny lobster fishery on the Mahe Plateau for the 2002/2003 fishing season. In order to improve and maintain proper management of this resources around the Mahe Plateau, the monitoring programme, set up in 1992, was continued this season to collect more information on the spiny lobster stock. Following recommendations made after the 2001/2002 lobster fishing season, a total of 25 licenses were issued in 2002/2003 namely fourteen on Mahe, six on Praslin and five on La Digue. Similar to previous seasons, the most frequently used lobster fishing techniques was snorkelling which involved 21 fishing units, whilst only two units used the trap method and two used both snorkelling and trap. For this three-month fishing season, a total of... |

| This report provides a broad assessment of the current status of coastal tourism in Tanzania and identifies the priority actions that need to be taken in order to develop a sustainable coastal tourism industry. Tourism is one of Tanzania's leading economic sectors, providing employment, foreign exchange and international recognition. For many years, tourism has relied solely on the superb wildlife found in the country. It is only recently that the need to diversify away from wildlife tourism and focus on coastal and cultural tourism has been recognized. |

| Ecological research, especially work related to conservation and resource management, increasingly involves social dimensions. Concurrently, social systems, composed of human communities that have direct cultural connections to local ecology and place, may draw upon environmental research as a component of knowledge. Such research can corroborate local and traditional ecological knowledge and empower its application. Indigenous communities and their interactions with and management of resources in their traditional territories can provide a model of such social-ecological systems. As decision-making agency is shifted increasingly to indigenous governments in Canada, abundant opportunities exist for applied ecological research at the community level.... |

| This document – an integrated Coastal Area Management (ICAM) Action strategy for the Nyali-Bamaburi-Shanzu area is the outcome of a participatory process to reach a broad consensus on how to address these critical coastal management issues at the site, as well as gain experience in ICAM for application to other areas in Kenya. Foe each issue, Findings of fact are presented. These provide background information about the topic, focusing on its significance and the causes and consequences of the problem. Management objectives and implementation strategies are set forth. |

| The purpose of this document is to begin a dialogue in Zanzibar about how government, in partnership with local communities and the private sector, can carry out integrated planning and management for coastal resources and regions. It is meant to serve two purposes: To provide a starting point f or addressing the urgent coastal issues facing the Chwaka Bay-Paje Area. It is hoped that the strategy outlined in this document developed through an open, participatory process will provide a basis for avoiding and resolving problems at the site. To enrich and inform the discussion on ho w to address increasingly urgent coastal management problems nation wide. It is hoped that the Chwaka Bay-Paje Area can serve as a model for other areas and help us move forward... |

| Community based natural resource management groups contribute to landscape scale ecological change through their aggregation of local ecological knowledge. However, the social networks at the heart of such groups remain invisible to decision makers as evidenced in funding cuts and strategic policy documents. Our research is a pilot study of the social networks in two peri-urban landscapes in Victoria, Australia. We describe the social network analysis undertaken with regard to natural resource management issues. The findings are assessed against the qualities of resilience: diversity, modularity, connectivity, and feedback loops. A social network analysis tool is discussed with participants to assess its usefulness on-ground and with agency staff... |

| Wetlands in most parts of the world are under threat of over-exploitation partly because their socio-economic value is not well known. Yala Wetland, the largest freshwater wetland in Kenya, with a large part of it bordering Lake Victoria’s shoreline, faces even greater threats of extinction. This wetland measures about 17,500 ha and is host to a number of indigenous fish species, animals and plants which are exploited by the local communities for subsistence and commercial purposes.There has been pressure to reclaim portions of this wetland for agricultural activity. So far, 2,300 ha has, indeed, been drained for commercial agriculture. Furthermore, it is difficult to control effort in the exploitation of the remaining wetland resources since the... |
