Write a speech on "concrete forest and how to make them sustainable
Answers
Answer:
The federal environment and acting cities minister, Greg Hunt, on Tuesday pledged to increase the number of trees in Australian cities. In a bid to fight higher urban temperatures, the plan will set targets for tree cover.
This is part of a green revolution spreading through the world’s cities. From New York to Singapore, urban areas are undertaking bold “greenspace” initiatives – removing concrete and allowing trees and vegetation back in.
Some of the benefits include replacing the ugly infrastructural trappings of vehicles and motorways as well as cooling cities, absorbing air pollution and minimising runoff. These greenings further have mental health benefits, by bringing residents and visitors alike back in
Sustainable forest management is the management of forests according to the principles of sustainable development. Sustainable forest management has to keep the balance between three main pillars: ecological, economic and socio-cultural. Successfully achieving sustainable forest management will provide integrated benefits to all, ranging from safeguarding local livelihoods to protecting the biodiversity and ecosystems provided by forests, reducing rural poverty and mitigating some of the effects of climate change.[1]
The "Forest Principles" adopted at The United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 captured the general international understanding of sustainable forest management at that time. A number of sets of criteria and indicators have since been developed to evaluate the achievement of SFM at the global, regional, country and management unit level. These were all attempts to codify and provide for independent assessment of the degree to which the broader objectives of sustainable forest management are being achieved in practice. In 2007, the United Nations General Assembly adopted the Non-Legally Binding Instrument on All Types of Forests. The instrument was the first of its kind, and reflected the strong international commitment to promote implementation of sustainable forest management through a new approach that brings all stakeholders together.

Concrete jungle? We’ll have to do more than plant trees to bring wildlife back to our cities

These greenings further have mental health benefits, by bringing residents and visitors alike back into contact with the land.
But what about wildlife? Trees alone aren’t enough to bring back nature. In the rush to create greenspace, we have to make sure we build it in a way to help wildlife thrive. That will take careful thought and planning.
Nature paved over
Many of the world’s cities don’t have anything special to offer in terms of nature – either because they never had all that much in the first place, or they’ve long since been lost to urban development.
Melbourne is a case of the latter. James Boyce (in his book 1835) records:
By the time Anthony Trollope visited, then a city of 206,000 “souls” in the early 1870s, the city had already largely turned its back on the Yarra [River], drained the swamps, filled in the lakes and flattened the hills, so that Trollope knew “of no great town in the neighbourhood of which there is less to see in the way of landscape beauty”.
That sounds like many a world city.
London, New York, Hamburg, Madrid, Detroit, Chicago, Seoul and Singapore are among cities that have undertaken bold greenspace initiatives. These cities have recognised the distinct benefits that flow from connecting people back to the natural world.
Detroit and Singapore have strong biodiversity themes and that’s needed too given the global decline in wildlife. Such initiatives help us to view
