Besides, qualitative methods including focus group discussions and direct observations, were used. Community activities differed between the two groups of villages (close and far from the park). Furthermore, local communities benefited directly and indirectly from employment, ecotourism, and support through social services. Education level was a significant factor influencing the perception of the benefits gained from the park. Crop raiding was the biggest problem reported by most people in the study area (31.5%, n = 200), followed by livestock losses. This study revealed that the establishment and expansion of a protected area can have positive and negative socio-economic, cultural, and political impacts on the livelihoods of local people. Households close to the park had little access to land; thus, few of them practiced agricultural activities and had crop production incomes. The needs of local people and poverty alleviation should be considered as important factors during the planning and designation of protected areas (PAs) in order to meet conservation and livelihood goals. The objective of the present study was to assess the perceptions of impact of PAs on the livelihoods of local people in terms of costs and benefits in the area adjacent to Saadani National Park in Tanzania with those not adjacent to Saadani NP. \u0000 \u0000 \u0000 \u0000 Key words: Attitudes benefit sharing, livelihood, local communities, protected areas.","PeriodicalId":143839,"journal":{"name":"International Journal of Biodiversity and Conservation","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121901064","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}

Satellite maps from Landsat multispectral images were processed using Arc GIS 8 to assess land cover change overtime. Structured questionnaires, focused group discussions and interviews were used to gather relevant data on resident’s perception on the impacts of land use, land cover changes on climate variability. The statistical package for social science (SPSS) version 19 was used to analyze respondent’s perception on the impacts of land use land cover change on local climatic variability. Results indicate a slow change in dense forest of -2% between 2006 and 2012 when no large scale agricultural practice existed, as opposed to a rapid change of -14% between 2012 and 2015 when such practice existed, indicating a massive loss of forest cover. Plantations increase slightly between 2006 and 2012 (51 ha) but witnessed a massive increase (210ha) between 2012 and 2015. Residents of Nguti sub division attest that there has been variability in the climatic condition in the area experience in the form of increase temperature, reduction in rainfall and changes in seasonality.

Laying peaked in September (n = 24 pairs). Twenty-four breeding pairs were observed of which nine pairs had one-egg clutch and fifteen pairs laid two-egg clutches. Average clutch size was 1.6 ± 0.5 eggs (n = 24 nests). The incubation period averaged 36.2 ± 1.1 days (range 35-38 days, n = 16 nests). Nestling periods averaged 48 ± 3.9 days of age (range 43-56 days, n = 16 nests). Of 39 eggs laid in the 24 breeding attempts, 34 (87.2%) hatched and 22 (64.7%) of those hatchling fledged.

Some available data are either preliminary or localised, or focus on agricultural weeds that leave an ecological gap about IPSs. In order to establish this gap, a study was conducted to asses the impact of IPSs in Maputo Special Reserve. A stratified random sample was used to allocate five land use and land cover strata. Plots of 20 m diameter formed by two replicates were established in transects within plot of 160 m × 80 m and each invasive plants species number were counted and recorded. At every 10 km distance of the road side in different reserve directions, field plots of 10 m × 10 m were also established location and coordinates where invasive plants species occur recorded. With the ARCGIS 10.3 software, IPSs location coordinates were positioned on the map to create location. Data analysis was through calculation of diversity and evenness indices (Shannon-wiener (H') and Simpson (D'). Student’s t -test was used to compare diversity differences between the invaded and un-invaded sites. The result indicated the occurrence of 26 IPSs across all strata with Lantana camara and Eucalyptus sp being dominant.
