ABSTRACT Climate variability is currently one of the greatest environmental challenges facing humankind, whereby increased temperature and changing rainfall patterns are predicted to impact upon livelihoods in Tanzania. This study highlights the perceived impact of climate variability on availability and utilization of non-wood forest products (NWFPs) among rural households around the East Chenene Forest Reserve in Bahi District, Dodoma Region. The main objective of the study was to examine ...
ABSTRACT This study aimed at determining the quality of wild vegetables under different growing conditions. Data was collected using a self-administered questionnaire and single time collected samples from planted wild vegetables were laboratory tested to determine nutrient values. SAS statistical tool was used to analyse the data. Vitamin C content was found to be highest in Solanun scabrum (3.40 ± 0.1mg/100gm) under forest conditions, followed by Launaea cornuta (3.1 ± 0.1mg/100gm) under...
ABSTRACT The attainment of green economy and low carbon climate resilient development in Kenya may be hindered by competing human interest on forests and other natural resources. Eastern Mau forest has experienced anthropogenic disturbance through encroachment and forest fires; that situation prompted the deployment of heterogeneous forest management. This study aimed at comparing the soil carbon stocks and soil CO2 effluxes in different forest management regimes on as well as how soil tempe...
ABSTRACT This work reported in this dissertation was conducted in Kiwengwa-Pongwe Forest Reserve (KPFR) in Zanzibar. Specifically, the study assessed the forest structure, carbon stock and forest degradation. Eleven transects were laid out in the North – South direction and plots located along each transect. The distance between transects was 600 meters and plots were laid down systematically at intervals of 300 meters along each transect. Clusters of concentric circular plots of 5, 10 to ...
ABSTRACT There is no doubt that REDD+ payments can do many activities that lead to deforestation and forest degradation less attractive. However, countries considering participating in REDD+ mechanism, need information on what it would cost them to reduce emissions from deforestation and forest degradation. This study was delimited to estimate transaction costs of REDD+ project with the Advancing REDD+ in Kolo Hill pilot project in Kondoa District as a case study. Socio-economic and biophys...
ABSTRACT A study was conducted at Meru/Usa forest plantation to determine quality, stocking and yield of Pinus patula and factors influencing them. The Meru/Usa forest plantation compartments were categorized into affected and non – affected by root disease and insect defoliators. Systematic sampling method was used to align transect and plots in the compartment. 198 sample plots of 0.04ha were laid and measurements taken for estimation of stem quality, stocking, basal area and volume. The...
ABSTRACT The fragmentation of forests into smaller isolated patches is a threat to biodiversity conservation. Fragmentation reduces the forest area and increases forest edge effect. Reduction in forested area may lead to increased local species extinctions, while effects of increased forest edge alter species interactions by increasing the degree of interaction among edge and forest interior species. Intensification of land uses surrounding forest patches resulting from population increase ex...
ABSTRACT Forest ecosystems have been a valuable source of economic wellbeing of human populations for centuries, particularly to the forest adjacent communities. The relationship between human wellbeing and ecosystems consist of complex systems that are mostly nonlinear, uncertain and often not clearly understood. To enhance forest sustainability, the deliberate evaluation of ecosystem services, human interactions and appropriate ways to involve the public in management is imperative. However...
ABSTRACT The search for new principles in bio-control of plant pathogens different from the classical fungicides is of worldwide interest. The genus Streptomyces is the producer of about 80% of all known world antibiotics. It is of a major interest in bio control of plant pathogens. The study consisted of three steps: (i) collection of soil samples from different sites in the Mau Forest Complex and isolation of Streptomyces from these samples, (ii) screening for antimicrobial activity of the ...
ABSTRACT Economic represents a dangerous direct and indirect threat to forests, though many people in the world understand that forests are threatened, factors in society sometimes override conservation. Subsistence communities need to find fuel, income, food and on the other hand, industries want to continually grow and to do so they often find these things in the forest. Butterfly farming demonstrates that natural resources can be used profitably in a way that protects the environment as i...
ABSTRACT Mangala Village Land Forest Reserve is a productive forest under Community Based Forest Management being managed by the Mbangala Village Council. The forest reserve was established in 2010, at Songwe District in Songwe Region. Sustainable charcoal production in Songwe District has not received a systematic research assessment. To what extent the so called sustainable charcoal production adheres to sustainability principle is not clear. The aim of this study was to assess charcoal pr...
ABSTRACT The study on the economic valuation of Non-Timber Forest Products (NTFPs) and its implication for adaptation to climate change was conducted in four villages surrounding Iyondo Forest Reserve (IFR). The study specifically aimed at identifying and quantifying NTFPs for subsistence use and trade, examining factors influencing supply and demand of NTFPs, examining the total economic value of NTFPs and determining profit margin between different actors along the NTFPs market value chain...
EXTENDED ABSTRACT On a coastline, tidal water and air constantly reach land surface and/or aquifer. Tropical forests before or adjacent to this line are usually having a wide range of habitats. Jozani Groundwater Forest (JGWF) is one of the tropical coastal forests with a wide range of floral and faunal habitats. The forest (JGWF) has a significant role in biodiversity conservation and ecotourism. International bodies including UNESCO recognize JGWF as the most important part of Jozani-Chwa...
ABSTRACT Tanzania is rich in pine forests which have the potential to produce valuable resin. In recent years Tanzania has embarked on commercial resin tapping at Sao Hill Forest Plantation. However, current information on resin tapping in the country is scanty and unreliable. Knowledge of factors that affect resin productivity is important for it is those factors that can be manipulated to enhance resin yield. The focus of this study was to fill this knowledge gap by exploring some pine tr...
ABSTRACT A study was conducted in three villages of Nanyala ward in Mbozi District to assess the impact of mining activities on land cover and forest stock. Landsat images of 1991, 2000 and 2011 were used to assess the trend of land cover changes. The Forest was stratified into mined and un-mined forest area. A concentric circular shaped sample plot with sampling intensity of 0.19 % was used. 70 sample plots were laid and measurements were taken for estimation of stocking, basal area, volume...
