The Green Belt Zone has broadly three main categories of uses, viz. agriculture and farming, forest and land regeneration and recreation. Their development is designed to promote biodiversity enhancement, environmental management, land regeneration and water management, with technology transfer of the above activities for wider application. This will make the Green Belt not only an asset for Auroville and the surrounding villages, but also a National Resource Centre (NRC) for sustainable development.
Agriculture and farming
The western part of the Green Belt, consisting of eris, natural drainage channels and village settlements, is reserved for intensive agricultural development. The area involved covers approximately 486 Ha. At present these lands are vacant or marginally used. They will be utilised to set up prototype farms for raising appropriate crop categories that can be efficiently produced in differing geographic conditions in Tamil Nadu in order to replicate them for the benefit of farmers in those areas.
Auroville's ongoing work in water management, soil conservation, organic farming and seed collection, which is being carried out in collaboration with State, national and international research institutions and agencies, will promote the policies of food security and optimisation of agro-economic potential both locally and nationally.
Forest and land regeneration
The eastern part of the Green Belt, which has already been developed with dense plantations of trees, acts as a barrier against cyclone-strong winds coming from the coast, which were till recently the main cause for soil erosion, gully formation and degradation of land.
These lands occupy 544 Ha. They will be utilised to strengthen the ongoing work of land regeneration, re-establishing indigenous forest vegetation, propagation of biodiversity through gene pools and seed banks, and instituting zero runoff parameters and practices. This part of the Green Belt will also provide the Auroville township with opportunities to carry out waste water treatment and recycling, solid waste management and experiments for producing alternate energy through use of biomass and wastes. In this regard Auroville is collaborating with State and central government agencies.
One of the several purposes of a Green Belt is also to provide open-air recreational facilities for the inhabitants of Auroville and its visitors. An area of 260 Ha has been designated for this purpose, which will also include a modern crematorium park as well as agro- and social forestry for the benefit of neighbouring villages.
