WORLD WATER DAY 2011
will be the United Nations Agency for Human Settlements (UN HABITAT) to coordinate the
March 22, 2011 initiatives to
World Water Day with the theme "Water for
the City ': how to respond to the challenges of urbanization. " World Water Day 2011, aims to be an opportunity to encourage governments, local governments, public and private organizations, banks, associations and communities around the world to take action on problems such as water resources and ; the waste urban environments.
Today the planet one person in two lives in an urban context and cities are growing at pace. 93% of the processes of urbanization takes place in poorer countries or in developing countries. In 50% of the cities are expanding as a result of an increase in population, 25% for migration from rural areas and in the remaining 25% due dell'inglobamento of rural land in urban areas.
The world's urban growth and 'represented largely by the expansion of slums that are growing at an extraordinary rate: it is estimated that over the period 2005-2020 these to increase their population with an average of 27 million people annually, worldwide.
Managing a city and 'very complicated: it is necessary to adopt a different approach depending on the type of urban environment with which we must confront. Among the challenges that a city faces, in addition to those strictly social and structural, are becoming increasingly important as environmental
One of the most critical of the administration of a city is the management of sanitation and water resources. Few local governments, particularly in developing countries, have found a sustainable solution to the issue of urban water services, too often beset by problems water pollution.
E 'is also increasingly evident that the water sector will suffer the effects of climate change, particularly due to the impact of floods, droughts and other extreme events of nature. It is expected that the availability of water resources will change both qualitatively and quantitatively with consequent complications in the implementation of distribution networks, service disruption and rising costs for water services and waste water collection.
In other respects, however, urbanization has increased opportunities for economies of scale and infrastructure development than achieved in rural areas.
The city of the future will benefit from an integrated urban management. With regard to the water this will mean the adoption of more efficient technologies for water treatment, an increase in water reuse, better management of demand and the minimization of environmental pollution.
In this context the objective of World Water Day 2011, and 'draw the international attention on the challenges and opportunities presented by water management in urban contexts. We want to raise awareness of the adverse conditions on world on global water management and to encourage those who are 'vested with decision-making power to seize the opportunity to address these challenges. Showing the success stories you try to encourage decision makers to initiate and support reforms and approaches that look to the future.
To understand what the real challenges of urban management of water resources, World Water Day 2011 will address five basic approaches:
- L ' Urbanization: the impact of rapid urban population growth and those in poorer areas.
- L ' pollution: the impact of industrialization, water pollution and environmental degradation.
- administrative and management issues: how to implement and support reforms aimed at managing urban utilities and improving governance. The
- economic investments: the need to increase investment in urban water, in sanitation, water management and waste. The
- Climate Change: the impact of climate change, conflict and natural disasters on urban water systems and waste management.
World Water Day 2011 will involve the leaders of the Maximum file levels and will provide an opportunity to launch a series of initiatives that seek to reach a huge audience for the current year and those to come. Of utmost importance are considered mass participation and exchange of experiences.
Not only that, World Water Day 2011 will involve the health sector, the economy, infrastructure as well as the school, energy and environment so that everyone has a role in the evolution of complex urban issues.
The city \u200b\u200bthat hosts major events worldwide this year is Cape Town, but wherever they are numerous initiatives awareness.
