Living in a world facing environmental crises like climate change, global warming etc. appears to be disastrous for humanity. However, the worst victims of these crises are the people living in urban cities. Though they may be economically better off than people living in rural areas, the ironic fact is that they have to face the negative implication of environmental crises more severely and fatally than people in backward areas of the nation. They have no option but to live in an environment with rising air, water and noise pollution as well as soaring temperatures. These all are making the lives of the urban people difficult, making them feel as if they are living in hell. The city dwellers belonging to almost every age group are facing health issues like asthma, T.B., irritation in the eyes, heart and lung ailments etc. Making the situation worse, deforestation has been carried out on a large scale to make residential spaces for the increasing human population in the city. The green belt as earmarked in and around certain urban settlements like the ridge area in Delhi and Array Forest in Mumbai has been reducing day after day to meet urban settlement needs. The adoption of the Miyawaki technique could give new life to the dying urban ecosystem and decaying environmental quality. The technique allows for afforestation to small but dense patches of areas within the city limits, which are filled with different native species of plants and trees. The paper discusses the environmental issues, primarily noxious air being inhaled by city dwellers in India and the usefulness of the Miyawaki Technique in dealing with such issues along with the pros and cons of using such techniques. It also studies certain existing laws which indirectly support and safeguard Miyawaki plantation. Further, the paper also throws light upon certain Judicial pronouncements which support this technique along with suggestions for effective implementation of the technique.
