Zimbabwe is the second most industrialized country in SADC, after South Africa. Industries are concentrated around Harare, with ore smelters located close to the ore sources (principally along the Great Dyke). A combination of vehicle emissions, dust and smoke from domestic fires is a potential air quality concern in larger cities such as Harare. Water is not generally abundant, and the maintenance of water quality is a serious issue. Biodiversity preservation
Zimbabwe has a rich biotic heritage and is highly dependent on tourism. It has a long history of biodiversity preservation, through the national parks, forest reserves and innovative community-based sustainable-use schemes such as CAMPFIRE. Nevertheless, the natural resources are under pressure from a growing population with limited economic alternatives. Land quality
Zimbabwe has the greatest fraction of its land area in good quality agricultural land. The economy of Zimbabwe has a large agricultural component, and the majority of people are dependent on the land. The distribution of people and productive agricultural resources is uneven, leading to problems of land degradation where large numbers of people and livestock are concentrated on marginal lands. Freshwater resources
The Zambezi River in the north is one of the largest rivers in Africa, but does not currently supply water to the rest of the country, which is water-scarce in most parts. The geology is generally not conducive to large groundwater supplies. Climate change
Like the rest of southern Africa, Zimbabwe is strongly influenced by fluctuations in rainfall. An improvement in the water balance as a result of climate change would be a great benefit; increase water stress, on the other hand, would be a substantial development challenge. Zimbabwe environmental problems like erosion of its agricultural lands and deforestation. By 1992, deforestation was progressing at the rate of 70,000–100,000 ha...
