OVERVIEW
EE&CC approch

   Making environment and development hand in hand by taking the confidence of the society is a looming problem of the 21st century. Population explosion, depletion of fossil fuel reserves, global warming, under-performing ecosystems, extinction of species etc needs urgent attention. International summits and conferences are ending up without substantial results. Workable solutions are the need of the hour to protect ourselves and our generations.

As per the UN statistics by the year 2030, nearly 60% of the world population are going to be accommodated in cities. Cities are the centres of order if managed efficiently or it can be centres of chaos otherwise. Hence effective environment management solutions at city/metropolitan area level has substantial contribution for the sustainability of the ecologically overshooting earth.

Two strong indicators of sustainability have been formulated based on UN sustainability research. These indicators are ENVIRONMENTAL EFFICIENCY (EE) & CARRYING CAPACITY(CC) which are evolved from three important terms from UN sustainability research literature. They are as follows.
1. Human Development Index of UNDP (HDI)
2.Biocapacity (Bc) and
3.Ecological Footprint (EFp) of WWF


Environmental Efficiency(EE) is evolved based on an output/input approach while carrying capacity is evolved based on capacity/consumption which should not be less than one on sustainability considerations. World Countries analysis has been carried out based on UN data to demonstrate its effectiveness and based on which some international environment management tips are proposed vide the conference paper at GLOBAL SUBMIT LONDON 2012. EE and CC monitoring can be done between states and between metropolitan regions within the nations by adopting the methodology formulated by UNDP and WWF and it can be taken up alongwith the Global Urban Observatory programme of UN Habitat.

Using the possibilities of Geographical Information System (GIS) and Remote Sensing it is possible to prepare the EE and CC map of the city/metropolitan region based on proxy indicators which can effectively be used for environmental decision making and for infrastructure prioritisation.
