Urbanization is ongoing process throughout the world. Hyper-urbanization with out environmental planning is destructive not constructive. Urbanization and urban greenery or urban forestry’s be a foil for quality of life. Urban tree foliages are not only beautiful in themselves but add beauty to their surroundings.
Trees add color to the urban scene, soften the harsh lines of buildings, screen unsightly views, and provide privacy and a sense of solitude and security, while contributing to the general character and sense of place in communities. Beyond aesthetics and emotional well-being, trees perform important functions that protect and enhance city dwellers’ health and property.
Trees literally clean the air by absorbing air pollutants and releasing oxygen. They reduce storm water runoff and erosion; they temper climate; they can save energy; they create wildlife habitat; they can improve health, serve as screens, and strengthen community. They can even help contribute to a community’s economy and way of life.
Good quality green space plays a vital role in enhancing the quality of urban life. Urban green spaces help to make the neighborhoods more attractive to live in and provide opportunities for city dwellers to relax, take exercise, play sport and meet friends and neighbors. The existences of high quality urban green space contributes to wider Government objectives such as improve health, more sustainable neighborhood renewable and better community cohesion, especially in more deprived communities.
In order to extend their usable territory, urban developers often reshaped natural landscapes, leveling hills, filling valleys and wetlands, and creating huge areas of made land. On this new land, they constructed a built environment of paved streets, houses, factories, office and buildings. In the process they altered urban biological ecosystems for their own purposes, killing off animal populations, eliminating native species of flora and fauna, and introducing new and foreign species.
Thus urbanites, as Ann Spirin has written, constructed a built environment that replaced the natural environment and created a local micro-climate, with different temperature gradients and rainfall and wind patterns than those of the surrounding countryside. City entrepreneurs and industrialists were actively involved in the commodification of natural systems, putting them to use for purposes of urban consumption. The exploitation of urban greenery to provide fuel for commercial, industrial and domestic uses is the prime cause.
The government has set targets to track and measures improvements in urban green space quality. With in a broader aim to enhance ‘liveability’-improving the quality and safety of public spaces and local environments and people’s enjoyment of them. There are wide variation in the level of satisfaction with urban parks and green spaces. Some local authorities would have to increase residents‘s satisfaction by considerable margins if the aggregate national target was applied locally.
The urban planning system has a key role in ensuring there is sufficient high quality urban green space. The pressure for additional housing and business in towns and cities makes existing urban green space attractive as potential developments sites. Planner not only need to ensure green space is protect and enhanced where appropriate but also to help to ensure suitable opportunities are taken to provide new space when development and regeneration schemes go head.
To help balance the needs of urban development and green space provision, planning authorities need to develop a vision of the value and role of green space which is shared by local key partners and citizens and is clear to developers. This in turn needs to be based on a rigorous assessment of the adequacy of existing green space provision and the way it might if necessary be improved.
Green space strategies play a key role in ensuring a local authority meets the expectations of national green space policy, in both its roles as community leader and planning authority. Strategies should help to articulate an authority’s vision for green space, the contribution that green space makes to other services ( Such as health, social care, safety, education) and the goals the authority wants to achieve, plus the resources, methods and time needed to meet these goals.
Local authorities need better guidance on the software tools (integration and development of Geographic Information System) available to map green space provision and access.
In the ultimate analysis, urban greenery management and economic development are mutually supportive aspects of the same agenda. The participatory community-based development programs appear to be most effective entry points for urban greenery management and sky scarping urbanization. The sustainability of urbanization is only possible with urban greenery.
