We think we understand environmental damage: pollution, water scarcity, a warming world. But these problems are just the tip of the iceberg. Food insecurity, financial assets drained of value, and a rapid rise in diseases of animal origin are among the underreported consequences of an unsustainable global system. In this volume, experts explore these hidden threats along with the central question of how we can develop resilience to these and other shocks.

Cities are perhaps one of humanity's most complex creations, never finished, never definitive. They are like a journey that never ends. Their evolution is determined by their ascent into greatness or their descent into decline. They are the past, the present and the future. Cities contain both order and chaos. In them reside beauty and ugliness, virtue and vice. They can bring out the best or the worst in humankind. They are the physical manifestation of history and culture and incubators of innovation, industry, technology, entrepreneurship and creativity. Cities are the materialization of humanity's noblest ideas, ambitions and aspirations but when not planned or governed properly, can be the repository of society's ills. Cities drive national economies by creating wealth, enhancing social development and providing employment but they can also be the breeding grounds for poverty, exclusion and environmental degradation. The 21st Century is the Century of the City. Half of humanity now lives in cities, and within the next two decades, 60 per cent of the world's people will reside in urban areas. How can city planners and policymakers harmonize the various interests, diversity and inherent contradictions within cities? What ingredients are needed to create harmony between the physical, social, environmental and cultural aspects of a city and the human beings that inhabit it? This report adopts the concept of Harmonious Cities as a theoretical framework in order to understand today's urban world, and also as an operational tool to confront the most important challenges facing urban areas and their development processes. It recognizes that tolerance, diversity, social justice and good governance, all of which are inter-related, are as important to sustainable urban development as physical planning. It addresses national concerns by searching for solutions at the city level. For that purpose, it focuses on three key areas: spatial or regional harmony, which examines the main drivers of urban growth in the developing world and explores the spatial nuances of economic and social policies; social harmony, which presents and analyzes new data on urban inequalities worldwide and describes the types of shelter deprivations experienced by slum dwellers in developing world regions; and environmental harmony, which examines the role of cities in the climate change debate, and the impact of global warming on the most vulnerable cities. The report also assesses the various intangible assets within cities that contribute to harmony, such as cultural heritage, sense of place and memory and the complex set of social and symbolic relationships that give cities meaning. It argues that these intangible assets represent the soul of the city and are as important for harmonious urban development as tangible assets. Harmony within cities, argues the report, is both a journey and a destination. Published with UN-HABITAT

The State of the World's Children 2011: Adolescence - An Age of Opportunity examines the global state of adolescents; outlines the challenges they face in health, education, protection and participation; and explores the risks and vulnerabilities of this pivotal stage. The report highlights the singular opportunities that adolescence offers, both for adolescents themselves and for the societies they live in. The accumulated evidence demonstrates that investing in adolescents' second decade is our best hope of breaking the intergenerational cycle of poverty and inequity and of laying the foundation for a more peaceful, tolerant and equitable world.

This is the 7th edition of the FAO's biennial report on the state of global forest resources, recent developments and emerging issues in the forest sector. This edition focuses on progress towards sustainable forest management at the regional and global levels, with each regional report structured according to seven thematic elements: the extent of forest resources; biological diversity; forest health and vitality; productive functions of forest resources; protective functions of forest resources; socio-economic functions; and legal, policy and institutional frameworks. These summaries are based on the most current information available, including new data from the Global Forest Resources Assessment 2005 (FRA 2005). The report goes on to consider 18 key issues in the forest sector, including: climate change, forest landscape restoration, forest tenure, invasive species, wildlife management and wood energy. The overall conclusion is that whilst progress is being made, it is very uneven with those regions with developing economies and tropical ecosystems continuing to lose forest area whilst lacking adequate institutions to reverse this trend. The biggest limitation for evaluating progress is weak data, with many countries lacking the financial resources to undertake national forest assessments.

This is the sixth edition of the biennial report on the current state of global forest resources and recent developments and emerging issues in the forest sector. It includes contributions from key non-governmental organisations and from individuals, as well as articles written by FAO staff. This edition focuses on options for sustainable forestry management to maximise the sector's economic viability, and issues discussed include forest resources, conservation aspects, institutional issues and legal frameworks, international policy developments, the economic benefits of agroforestry, wood energy production, import tariffs and non-tariff measures, and the impact of violent conflicts on forest resources.
