Mozambique´s abundant natural resources and geography create both opportunities and risks.  The exploitation of oil, gas and minerals as well as biodiversity, such as wildlife, fisheries and forests,  help to promote economic growth but when conducted unsustainably, fuel corruption and often lead to resource conflict.  The long coastline and extensive borders serve as a commercial gateway to six countries and transcontinental trade routes. Gorongosa National Park and the vast Niassa National Reserve are fragile refuge areas for lions, elephants and other endangered species threatened by rampant poaching  for bush meat and wildlife trafficking. Low-lying coastal plains cover nearly half of the land mass leaving large parts of the country vulnerable to cyclones and extreme flooding, including important population, commerce and trade centers.
