People depend on biodiversity in their daily lives, in ways that are not always apparent or appreciated. Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and on occasion, may even cause political conflict. There is growing concern about the health consequences of biodiversity loss and change. Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services. Great Indian Bustard Sanctuary is a wildlife sanctuary for the great Indian bustard (Ardeotis nigriceps) at Solapur, Maharashtra, India. The land is drought-prone and semi-arid. Maharashtra is one of the six states of India where great Indian bustards are still seen. The great Indian bustard at Nannaj was first identified By Mr B.S.Kulkarni in 1972 and with his constant efforts to save the bird had resulted in Dr. Salim Ali visiting Nannaj and starting a research project.
