Item Determinants of access patterns to goods and services from wetlands in Tanzania and the impact on sustainable wetland management(Academic Journals [Commercial Publisher], 2012) Mombo, Felister; Speelman, Stijn; Kessy, John; Hella, Joseph; Huylenbroeck, Guido vanWetlands perform vital role in providing useful goods and services to mankind. Because of their importance, human beings interactions with the wetlands’ physical environment have caused some of them to be highly degraded. Due to characteristic nature of wetlands being a common pool resource (CPRs), most researchers claim their degradation to be a result of poor institutions governing the interactions. Wetlands in Tanzania are very useful especially, in areas where agriculture is most prevalent. High pressure to exploit fertile and moist land in those areas has caused wetlands to be highly degraded. This study focused on the rules and regulations governing the resources access from the wetlands using Kilombero Valley as a case study. The study used choice modelling to identify the determinants of the access patterns and their impacts on wetland sustainable management. The results showed that physical nature of resources and characteristics of the users such as location, income and education determine what type of access one chooses to accrue products and services from the wetlands. To ensure wetland sustainable management, the policy makers and conservationists should consider these factors in enacting rules and regulation which would govern human interactions in the wetlands. Payment for environmental services could be used to enhance such options.Item Ratification of the ramsar convention and sustainable Wetlands management: Situation analysis of the Kilombero valley wetlands in Tanzania(Academic Journals, 2011) Mombo, Felister; Speelman, Stijn; Van Huylenbroeck, Guido; Hella, Joseph; Pantaleo, Munishi; Moe, SteinIn recent years, the Kilombero Valley wetlands in Tanzania was designated and added to the Ramsar convention’s list in an attempt to improve its social, economic and environmental values. This study, carried out in selected sites within the Kilombero Valley wetlands, uses a participatory approach to analyze the existing situation and to reflect upon the quest for sustainable management as defined by Ramsar convention. The empirical findings reveal that the Kilombero Valley wetlands are an important source of livelihood for 87% of the dwellers in the area. Moreover, the wetlands also contribute significantly to welfare outside the area as 70% of the country’s hydropower depends on water regulation functions of this wetland and they are the source of a diverse number of streams, adding to their biological and ecological value. The study furthermore revealed that the current institutional arrangement for the site threaten the sustainability of the wetlands, despite its addition to the Ramsar convention’s list. A more detailed study on appropriate incentive mechanisms for the sustainable management of the wetlands, which would help to internalize the negative effects created by the users, is recommended.
