The district is a reflection of typical rural life in Africa South of Sahara where rural communities inhabiting dry woodlands and dependent on natural resources for their sustenance do not consider indigenous tree species as valuable resources of income. The study was conducted in the low lands of Rorya district-Tanzania to assess contribution of wild Acacia species for sustenance among rural communities. Ethnobtanical survey and standard sapling procedures were used for data collection and description of Acacia distribution patterns. Distribution and diversity of Acacia species is affected by multiple factors some of which could not be addressed by the arithmetic models employed in this study. Of all the sampled Acacia species, A. seyal ranked topmost as potential tree resource for a wider local and cross border market. Unlike other sampled Acacias, A. seyal has comparatively rapid biomass turnover within a short period. Density of A. seyal is much higher in swampy black cotton soils. Despite the economic potential of the species, significant proportion of Acacia woodlands is cleared annually for charcoal. Though Acacia seyal stumps coppices readily, combination of clearing and over grazing can convert the Acacia woodland to typical grasslands within a shorter duration of 20 years. At the same time, there is neither a conservation guideline nor land tenure arrangement in place for sustainable conservation. The study is recommending urgent legislative and land tenure reforms to control the current free access and encroachment that has nastily denuded the wood lands. Acacia being good source of pollen, commercial placement of bee hives is advocated as a supplementary economic activity in parallel with selling of wood fuel. \u0000 \u0000 \u0000 \u0000 Key words: Acacia, Vachellia, Senegalia, sustainable development.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125822046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The respondents comprised 55 females and 101 males, aged between 20 and 70 years. Semi-structured questionnaire was used. Only 57% of the respondents were aware of the proposed project, and the majority of these respondents reside in villages located closer to the game reserve. Their major concern was loss of biodiversity, which was more frequently expressed by those living close to the game reserve (58.3%) than by those living further away (5%). Respondents also expressed concerns about the lack of clarity regarding land compensation. The latter was expressed significantly more frequently by respondents residing close to the game reserve. This study demonstrates the lack of community awareness about the project.

The physical environment in this area has almost completly deteriorated as a result of declining rainfall and rising temperatures. A study was carried out to understand the dynamics of biodiversity in terms of climate variability in the Waza National Park. This study was based on both the trends of climatic parameters on biodiversity and perceptions of local populations over the last forty years. The adapted approach combines (i) the modeling of climate data through MINITAB 17 Software, (ii) the analysis of wildlife census data and (iii) the digital analysis of satellite images using ENVI 4.5 and QGIS 2.17 Software. The results showed a negative evolution of climatic parameters during the last forty years. The general negative trend of biodiversity evolution of both fauna and flora is a result of the continuous degradation of the Waza National Park. The results of different wildlife census, the spatial analysis and the perceptions of local people confirmed the trend to the degradation of the park and biodiversity losses. Concrete measures of management of the Park should be taken by stakeholders in order to hinder the biodiversity losses, including the construction of water ponds and cartesian wells as well as the enrichment of the park with woody species. \u0000 \u0000 \u0000 \u0000 Key words: Climate variability, land degradation, biodiversity dynamics, biodiversity losses, Waza Logone Plain, Cameroon.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124660972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty villages in Karatu district located between Ngorongoro Conservation Area (NCA) and Lake Manyara National Park (LMNP) were chosen for this study. The data were collected using semi-structured questionnaires administered to 133 local leaders in 20 villages. Findings indicated that attitudes of local leaders towards conservation in the village areas were positive. We observed that 90.3% of the village government members and 50% of the chairpersons considered charcoal making as detrimental to the environment and insignificant to the development of their villages. Majority of the respondents (80.0%) rated that village environmental conservation bylaws are having inadequate penalties for offenders in dealing with the current state of rapid environmental deterioration in village lands. The position of a leader was an important predictor as 87.4% of village chairpersons and 70.0% of the village government members were positive towards conservation in village lands.
