Abeer S Jabaji asked in Environment 4th Feb '13:Green Roofs have a long standing history, yet modern green Roofs are a relatively new phenomenon which were developed in Germany and has since spread to many countries.Green Roofs have numerous Environmental, Building and Economic benefits.What is the criteria to be implemented in order to make Green Roofs more widely spread and an integral part of urban landscaping? What strategies should governments adopt to make Green Roofs a fundamental component in reducing the carbon foot print worldwide?

Urban farming as strategy for a new community
Large cities have been built without a sustainable plan, urban farming on rooftops tops could be an opportunity to improve the quality of life.
Urban jungles desperately need green features for a more livable habitat.
While most of the modern metropolises- above all in Asia- have been built following business criteria over sustainable values, city planners didn’t put in account the issue of the quality of life.
Nowadays these issues are important only in the large, mature, environment conscious, western cities but it is also felt as important also in the new economies’ large cities like China.
Because there is no room for public green areas in an already fully built urban suburb the intent to cultivate green on roof tops emerges as a logical choice.
In terms of town planning the most notable aspect of this spontaneous trend is that it has nothing to do with the design of the public spaces and town planning. Urban farming – or urban gardening – on roof tops is most of the time a spontaneous initiative entirely organized by privates citizens. It represents somehow the overtaking of the citizen ’intelligence and common sense over a lackluster town planning policy.
Quite a few social benefits that have emerged from urban agricultural practices :better health and nutrition because of the organic and genuine nature of this food, and if put in the market it would increased income, employment, food security within the household, as well as offering activities for retired people. Social benefits are also concerning the quality of the urban habitat helping absorbing carbon smokes pollutions and, purifying the air as well as creating microclimates to refresh the city during summer heats.
Municipal offices should then engage as much as possible in promoting these activities as they are the main responsible of the poor balance between concrete surfaces versus green features.
Taxes on property should be reduced if the dedication on a green project is consistently developed, community-based farming projects should be financed by public means since urban agriculture saves energy (e.g. energy consumed in transporting food from rural to urban areas) allows to cut transportation and storage costs.
A green revolution has silently started in the big cities. It is an opportunity governments shouldn't waste as the environment emergency doesn’t just happens in the heart of Amazonian forest, but it actually starts form the way we live our daily life.View all replies to this question
