| dc.description.abstract | The depletion of forest biomass and declining of forest-dependent wildlife populations are ur
gent ecological and societal issues resulting from human activities such as deforestation and
land-use changes. This study aims to comprehend the influence of anthropogenic activities on
forest biomass and the population of wildlife dependent on forests, and to formulate appropri
ate management measures. Specific objectives include forecasting forest land loss in Tanzania,
analysing mathematical model describing the impact of human activities on forests and wildlife,
examining the influence of fuzzy parameters on model dynamics, and evaluating the effects of
economic measures and technological efforts on conservation. The study considered Tanzania
where local communities heavily rely on forest resources for their livelihoods. This region also
supports a rich biodiversity of wildlife species, where the forest provides essential habitats and
resources for their survival. Furthermore, the study also acknowledged the existence of vari
ous human activities carried out in the area which may have a significant impact on the forest
ecosystem and the wildlife populations that depend on it. Four models are presented: a time
series model and three dynamical system models. The key findings include: (i) The univariate
time series model accurately predicts an increase in forest land loss in Tanzania with a 96.2%
accuracy rate (MAPE = 0.0377), highlighting the urgency for sustainable forest management
practices and conservation policies. (ii) Depletion of forest biomass due to human activities
has severe implications for wildlife survival and ecological balance. Achieving this balance re
quires ensuring the growth rate of forest biomass and wildlife populations exceeds their rates of
utilisation and depletion, respectively. (iii) Incorporating fuzzy parameters improves model re
liability by accounting for uncertainties in climate, geography, and human activities, enhancing
decision-making processes. (iv) Economic measures and technological efforts have the po
tential to conserve forest biomass and wildlife populations. However, careful implementation
and comprehensive understanding of forest ecosystem dynamics are crucial to prevent desta
bilisation. The study emphasises the need for interdisciplinary collaboration and stakeholders
engagement to ensure sustainable forest use and conservation, considering the complexities and
uncertainties of natural systems. Balancing forest conservation with socio-economic needs is
key for the well-being of local communities and future generations. | en_US |
