“…While the absence of evidence is not necessarily evidence of absence, ongoing ecological and nutritional shifts suggest that these results may, in part, be rooted in dietary trends. The influx of farmed and processed foods, anthropogenic changes such as paved roads adjacent to Hadza land (Fyumagwa et al, ; Hopcraft et al, ), climate change (Mabulla, ), increased pressure from ecotour companies (Butovskaya, ), and the increased presence of missionaries and nongovernmental organizations (NGOs) (Yatsuka, ) all impact not only diet composition of Hadza foragers, but perhaps sex differences in consumption patterns as well. These dietary shifts may contribute to homogenization of diet between the sexes and the seasons and perhaps the differences in diet breadth reported here also.…”

Objectives: Studies of dental microwear of bioarchaeological assemblages and extant mammals from museum collections show that surface texture can provide a valuable proxy for reconstructing diets of past peoples and extinct species. However, no study to date has focused on occlusal surface microwear textures of living hunter-gatherers. Here we present the first such study of the Hadza foragers of Tanzania. Methods:We took high-resolution dental impressions of occlusal surfaces for a total of 43 molds representing 25 men and women, 1-3 samples each, at different times during the rainy and dry seasons. Dental replicas were prepared and scanned by confocal profilometry and standard microwear texture parameters were calculated. Central tendencies and dispersions of variable scores were compared by season and by sex.Results: We found no differences between sexes or seasons in texture attribute central tendency, but some for dispersion. Females had notably low microwear texture dispersion in the dry season while males had higher dispersion in some attributes, particularly in the dry season. These differences seem to be driven primarily by low variance among females in the dry season.Conclusions: This study demonstrates microwear texture data can be generated for living foragers. Given caveats of small samples available and consideration of foraging groups in transition, this study hints at variation in microwear texture dispersion between sexes and seasons for the Hadza, suggesting that such analyses might be of value for assessing hunter-gatherer diet.

“…Another factor may be the sharp debate [15][16][17][18] and the adverse publicity [19] that a proposed road through the Serengeti National Park has generated where there are serious concerns about severing the wildebeest (Connochaetes taurinus) and zebra migrations. No one wants international pressure or political and polarized arguments arising in another part of the country.…”

Roads through protected areas are generally believed to have many adverse environmental effects but there are few examples of road building being halted for environmental reasons. In Katavi National Park, western Tanzania, plans to upgrade a murram road connecting regional capitals have been stopped in favour of retaining the sanctity of the protected area. Despite empirical evidence suggesting upgrading would damage trees, increase traffic, adversely affect large mammals, and result in more litter, the decision not to upgrade was likely made for general environmental and sociopolitical reasons rather than on consideration of ecological data per se. This suggests that conservation scientists, while remaining independent, need to work with politicians to achieve environmentally friendly outcomes regarding tropical highways.

“…New problems such as road building are always arising (e.g., Hopcraft et al. ). Erosion of wildlife populations aside, TANAPA has largely prevented habitat encroachment because it is relatively well funded through photographic tourist income; tourism in Tanzania amounted to US$1.95 billion in 2014.…”

“…Some of these declines are attributed to poaching within PAs (e.g., Metzger et al 2010) and altered hydrology from water demand outside PAs (e.g., Manase et al 2010) or both (Caro et al 2013), as well as many other factors, including habitat modification, wildlife diseases, illegal fishing, and competition with illegal cattle grazing. New problems such as road building are always arising (e.g., Hopcraft et al 2015).

Tanzania, arguably mainland Africa's most important nation for conservation, is losing habitat and natural resources rapidly. Moving away from a charcoal energy base and developing sustainable finance mechanisms for natural forests are critical to slowing persistent deforestation. Addressing governance and capacity deficits, including law enforcement, technical skills, and funding, across parts of the wildlife sector are key to effective wildlife protection. These changes could occur in tandem with bringing new models of natural resource management into play that include capacity building, corporate payment for ecosystem services, empowering nongovernmental organizations in law enforcement, greater private-sector involvement, and novel community conservation strategies. The future of Tanzania's wildlife looks uncertain-as epitomized by the current elephant crisis-unless the country confronts issues of governance, embraces innovation, and fosters greater collaboration with the international community.
