How is the development of human settlement in Tanzania not sustainable because it has not combined socioeconomic development with environment conservation and protection?

Answer 1

The question suggests that socioeconomic development is being made at the expense of the (natural?) environment and that therefore such development will come to an end. You will need to look at conflict between socioeconomic development, (settlement, agriculture, water use) and environmental issues, (loss of wldlife, biodiversity, habitat, land degradation, erosion). What is the current state of these two aspects and where they are headed. A site worth checking: "Tanzania's Participatory Poverty Assessment has confirmed that most people in the country directly depend on the environment not only for income generating activities, but also to provide them with their basic needs, such as food, cooking materials, and medicine. Environmental problems currently threatening this dependence include land degradation, lack of accessible, good quality water, environmental pollution, loss of wildlife habitats and biodiversity, deterioration of aquatic systems, and deforestation.(1) Research suggests that these problems are affecting the well-being of the poor, as Participatory Poverty Assessment respondents were very concerned about what they perceived to be a critical decline in both the quantity and quality of key resources".
