Cities and biodiversity

In 1950, only three of the world's most populous cities were in
developing countries. Currently, only three of the world's most populous cities are in rich
countries. Cities occupy two per cent of the planet’s surface but their residents use 75 per cent of
the Earth’s natural resources. The megacities of the world can today be included among the
richest countries with regard to biodiversity.
=== Impacts ===
The impact cities have on biodiversity is a major concern as the health of both populations and
ecosystems is affected by unsound urban management. However, urbanization also has the
potential to contribute positively to human development and to the protection of the environment.
=== Biodiversity challenges for cities ===
Biodiversity challenges that are specific to cities, such as the provision of appropriate urban
infrastructure, sustainable transportation, adequate waste management and minimized industrial
pollution, constitute some of the most urgent issues on the local, national, regional, and
international levels, and are, to a large extent, within the cities’ jurisdiction. Therefore, the
involvement of local authorities in the global effort to protect all forms of life on Earth is essential.
=== Curitiba March 2007 ===
At the initiative of the Mayor of Curitiba, Mr. Carlos Alberto Richa, a meeting on "Cities and
Biodiversity" was held from 26 to 28 March 2007. Over 70 participants, including 34 mayors and
city officials from around the world, attended.
During the meeting, participants exchanged experiences and best practices on biodiversity and
agreed on a set of actions for the conservation and sustainable use of biodiversity and for
achieving the 2010 biodiversity target, which aims to achieve a significant reduction in the rate of
biodiversity loss at the global, regional, and national levels as a contribution to poverty alleviation
and other Millennium Development Goals.
=== The Curitiba Declaration ===
The Curitiba Declaration, adopted by this first-ever meeting on cities and biodiversity within the
framework of the Convention on Biological Diversity, reaffirms the urgency to achieve its
objectives in the urban world and to engage local authorities for the battle of life on Earth.
Particular emphasis was placed on raising public awareness and educating new generations, as
well as disseminating best practices and lessons learned through cooperation between cities. 
=== Curitiba’s Biocities Initiative ===
In response to the unprecedented challenges of global biodiversity loss, Mayor Richa of Curitiba
called for "the active engagement of local authorities," and added that he was "very pleased to
announce Curitiba’s groundbreaking Biocities Initiative." The initiative, a US$ 175 million project,
uses an enhanced participatory approach to create parkways and linear parks, and to protect
watersheds.

*Montreal Mayor Tremblay: "Biodiversity is the future of humanity. The rapid loss of biodiversity poses an environmental challenge of a global nature as serious as limate change. This message needs to be convened to stakeholders, United Nations agencies, national Governments, local authorities, development agencies, private sector partners, non-governmental organizations, knowledge and research institutions, and multilateral organizations, through one united voice. All citizens of the world must be empowered to translate this responsibility and obligation in their daily life as the priority of priorities."
*Ahmed Djoghlaf, the Executive Secretary of the Convention on Biological Diversity: "The year 2007 marks a paradigm shift in human history. For the first time, urban population exceeds rural population. Cities are growing mainly in developing countries, countries that are poor in terms of finances, but very rich in terms of biodiversity. As a result, the battle for life on Earth will be won or lost in cities. The Curitiba city and biodiversity initiative is a major contribution to ensuring that cities are part of the solution in response to biodiversity challenges facing the world."
