UNESCO organized the Hangzhou International Congress, “Culture: Key to Sustainable Development” Hangzhou, China, 15 - 17 May 2013), with the financial support of the Government of the People’s Republic of China. The Congress’ 500 participants from 82 countries -- including high-level government representatives, United Nations entities, development banks and institutions, academia, the private sector and civil society as well as prominent experts -- addressed culture’s contribution to the social, environmental and economic development dimensions of sustainable development, to peace and security, and its crucial role in forging sustainable cities and building resilient societies, through heritage and creativity, as well as the potential of public-private partnerships in achieving these goals, thus providing an in depth contribution to several recommendations by the Rio+20 Conference. The participants adopted the Hangzhou Declaration “Placing Culture at the Heart of Sustainable Development Policies” , which recommends concrete actions to place culture at the heart of development policies.

In support of Rio+20 outcome paragraph 134 - We recognize that, if they are well planned and developed, including through integrated planning and management approaches, cities can promote economically, socially and environmentally sustainable societies. In this regard, we recognize the need for a holistic approach to urban development and human settlements that provides for affordable housing and infrastructure and prioritizes slum upgrading and urban regeneration. We commit to work towards improving the quality of human settlements, including the living and working conditions of both urban and rural dwellers in the context of poverty eradication so that all people have access to basic services, housing and mobility. We also recognize the need for conservation, as appropriate, of the natural and cultural heritage of human settlements, the revitalization of historic districts and the rehabilitation of city centres.

In support of Rio+20 outcome paragraph 136 - We emphasize the importance of increasing the number of metropolitan regions, cities and towns that are implementing policies for sustainable urban planning and design in order to respond effectively to the expected growth of urban populations in the coming decades. We note that sustainable urban planning benefits from the involvement of multiple stakeholders as well as from full use of information and sex-disaggregated data, including on demographic trends, income distribution and informal settlements. We recognize the important role of municipal governments in setting a vision for sustainable cities, from the initiation of city planning through to revitalization of older cities and neighbourhoods, including by adopting energy efficiency programmes in building management and developing sustainable, locally appropriate transport systems. We further recognize the importance of mixed-use planning and of encouraging non-motorized mobility, including by promoting pedestrian and cycling infrastructures.

In support of Rio+20 outcome paragraph 137 - Strengthen existing cooperation mechanisms and platforms, partnership arrangements and other implementation tools to advance the coordinated implementation of the Habitat Agenda with the active involvement of all relevant United Nations entities and with the overall aim of achieving, sustainable urban development.

In support of Rio+20 outcome paragraph 148 - We are concerned about labour market conditions and widespread deficits of available decent work opportunities, especially for young women and men. We urge all governments to address the global challenge of youth employment by developing and implementing strategies and policies that provide young people everywhere access to decent and productive work, as over the coming decades decent jobs will need to be created to be able to ensure sustainable and inclusive development and reduce poverty.

In support of Rio+20 outcome paragraph 149 - We recognize the importance of job creation by investing in and developing sound, effective and efficient economic and social infrastructure and productive capacities for sustainable development and sustained, inclusive and equitable economic growth. We call on countries to enhance infrastructure investment for sustainable development and we agree to support United Nations funds, programmes and agencies to help assist and promote the efforts of developing countries, particularly the least developed countries, in this regard.

Megacities are areas of intensive human activity, both economic and social, with corresponding tremendous energy consumption. Due mostly to the burning of fossil fuels to provide energy, megacities have concentrated emissions of air pollutants, greenhouse gases and waste heat, which impact terrestrial and aquatic ecosystems as well as air quality and climate. The negative impact of megacity emissions on local air quality has long been recognized, but it is only in recent years that their impacts on regional and global climate have received greater attention.
