With the support of global capital, big corporates have entered into developing countries. They have impacted world polity and the political economy of our countries in South Asia. So called development has become the political dictate. This is exclusive development and hence we may call it as "Developmentalism " which is largely against the wellbeing of the societies.  This kind of phenomenal development has strengthened the divide between rural and urban areas in SA. This is also not sustainable as it ruins the environmental resources. Finally, it has fractured democracy as visible in South Asian countries like India, Pakistan and Sri Lanka. Geographers must be sensitized to such issues. Interdisciplinary research may reveal these facts and also emerge with solid policy instruments to reestablish democracy, environmental protection and inclusive development.
