May 29 – June 3, 2005 2 (12) A DESIGN FOR ECO-SUSTAINABILITY: LESSONS FROM A STRESSED ENVIRONMENT IN MUMBAI Introduction: The importance of environmental sustainability is now well recognized even by the developing countries. However, the economic compulsions that have become even stronger in the face of the globalization, the cities are facing intense competitions to attract international capital and corporate offices leading to policies where environmental well being gets a lower priority. The current focus of planning in the city of Mumbai on the proposals like creation of new Central Business Districts, Information Technology parks, luxury housing townships, flyovers and freeways, shopping malls, golf clubs, multiplexes and other high-end entertainment centers, all designed to project an up market and global image illustrates the point. In the process, the city environment is under strain as never before, but unfortunately that does not figure in any calculation. Assessment of the impact of development projects on the ecosystems is now absolutely critical besides the technical, economic and political factors.

  • Fauna of Sanjay Gandhi National Park, Bombay (Vertebrates)
    B'D_ 1001. Surv. India, 92 (1-4) : 225~251, 1992 FAUNA OF CONSERVATION AREAS: FAUNA OF SANJAY GANDHI NATIONAL PARK, BOMBAY (VERTEBRATES) G. M. YAZDANI, M. S. PRADHAN & D. F. SINGH Zoological Survey of India, Western Regional Station, Pune. INTRODUCTION Among the four National Parks in the State of Maharashtra, Sanjay Gandhi National Park is a beautifully preserved green oasis within the confines of Bombay metropolis. The park exhibits an amazing diversity of terrain-beginning at just 30 meters above sea level, to almost SOO m and displays coastal, dry and mixed deciduous, and typical western ghat plateau habitats. It boasts of two big lakes and 2000 years old Kanheri caves. Due to its proximity to Bombay city, a lot of people have visited, studied and written about this Park, but unfortunately this information is all scattered and most of it deals with the bird fauna, as indeed it is a bird watcher's paradise (Abdulali 1981, Naik 1986, Monga 1986, Singh & Yazdani 1988). In this paper we have tried to present as a consolidated work, the vertebrate fauna of this Park. after an intensive survey from 1987 to 1989 under the special conservation area survey programme of the Zoological Survey of India. The groups were worked out as per the following: Pisces (GMY & DFS); Amphibia, Reptilia (DFS & MSP); Aves (DFS) & Mammalia (MSP). Tbe Park (Fig. 1 & lA) Sanjay Gandhi National Park (previously known as Krishnagiri Upawan and l~ter as Borivli National Park) is situated about 25 kms north from the heart of ,Bombay city and is only 8 kms from the shores of the Arabian Sea.

E XECUT IV E S UMMARY Disaster Risk Management (DRM) is based on the principle that the impacts of disasters can be reduced through appropriate preparedness, planning and management actions. The range of measures utilized in DRM policies, strategies and actions are ultimately meant to contribute to the safety and well-being of communities, at the same time protecting assets and development gains and improving services to population. The Disaster Risk Management Master Plan (DRMMP) is an analytical model based on international standards which is being prepared for Mumbai that will guide Mumbai in efficiently mainstreaming Disaster Risk Reduction (DRR) at the local level through a coherent set of policies, strategies and actions. The collaborative and participatory planning process adopted in the development of the DRMMP ensures consensus and ownership among the stakeholders and enables long term institutional sustainability. By adopting the DRMMP as a management tool for disaster risk management, Mumbai will be able to mobilize institutional and community resources and provide a coherent and efficient approach of actions prior, during and after a disaster.
