“Roads are generally perceived as infrastructure to deliver transport services, but they are more than that. They are major interventions in the hydrology of areas where they are constructed – concentrating runoff and altering subsurface flows. At present, water-related damage constitutes a major cost factor in road maintenance. Using ongoing research from Ethiopia, this article argues to reverse this and turn water from a foe into a friend and integrate water harvesting with road development.

Fluorine is an element abundant in nature. In the right quantities, it is essential for the development of teeth and bones. However, under specific conditions, the concentration of fluoride (F) in ground and surface water can exceed safety levels and becomes toxic for human health. This may lead to skeletal and/or dental fluorosis, two chronic biogeochemical diseases that occur in various countries around the world.

ABSTRACT This study compared the occurrence of skeletal fluorosis in chronic consumers of locally brewed alcoholic beverages and their matched controls in the Ethiopian Rift Valley. The study revealed that chronic alcohol consumers developed severe forms of crippling skeletal fluorosis quite early in life. The controls were either symptom-free or exhibited mild forms of the fluorosis. The study showed that crippling skeletal fluorosis was directly associated with the large volumes of the locally brewed beer and honey-mead consumption on a daily basis. Chemical analysis of the alcoholic beverages showed that high concentration of fluoride which was much higher than the fluoride in the water was used for the brewing process. From this study one would conclude that in communities residing in high fluoride areas, there should be awareness creation campaigns to point out the relationship of excessive consumption of locally brewed alcoholic drinks and skeletal fluorosis. Regulations should also be put in place to require producers of local alcoholic beverages to use low fluoride water for brewing.
