Goats have developed in harmony with local conditions of climate, terrain, vegetation, and even pathogens over centuries in many areas, while they have been blamed of causing environment degradation in other ones. The paper summarizes the situation of goat's population worldwide, the status of the breeds and the multiple implications of their conservation, the interactions of goats with other animal species (wild or domestic) and the main issues regarding the consequences of goat grazing from the environmental point of view. It underlines that most of the environmentally harmful effects of goat grazing arise from improper management practices at very high grazing pressures whereas goat grazing can be a useful tool for conservation if managed adequately. Moderate grazing pressures can be compatible with high levels of biodiversity and provide externalities, whereas high intensity at short term can be a valuable tool for weed control. Goat genetic heritage is seriously threatened and requires more studies and greater support from national and international institutions, in parallel with other efforts in rural development, especially for remote areas which hold an outstanding reservoir of livestock diversity adapted to the local conditions and managed by impoverished communities. A multidisciplinary approach of scientists, policy makers, rangeland managers and local communities is required for the design of future sustainable management plans.
