Throughout history water has confronted humanity with some of its greatest challenges. Water is a source of life and a natural resource that sustains our environments and supports livelihoods – but it is also a source of risk and vulnerability. In the early 21st Century;; prospects for human development are threatened by a deepening global water crisis. Debunking the myth that the crisis is the result of scarcity;; this report argues poverty;; power and inequality are at the heart of the problem.The 2006 Human Development Report continues to frame debates on some of the most pressing challenges facing humanity.

his 2005 Human Development Report takes stock of human development;; including progress towards the MDGs. Looking beyond statistics;; it highlights the human costs of missed targets and broken promises. Extreme inequality between countries and within countries is identified as one of the main barriers to human development—and as a powerful brake on accelerated progress towards the MDGs. The report suggests that the world's governments are faced with a choice. They can start a decade for development with the financial resources;; technology and capacity to end poverty or we could have a human development failure. “Business as usual” will not allow fulfilling the promises and the commitments made in 2000. The cost of this failure will be measured in human lives;; increased inequalities;; violations of human rights and threats to peace.

Migration;; both within and beyond borders;; has become an increasingly prominent theme in domestic and international debates;; and is the topic of the 2009 Human Development Report (HDR09). The starting point is that the global distribution of capabilities is extraordinarily unequal;; and that this is a major driver for movement of people. Migration can expand their choices —in terms of incomes;; accessing services and participation;; for example— but the opportunities open to people vary from those who are best endowed to those with limited skills and assets. These underlying inequalities;; which can be compounded by policy distortions;; is a theme of the report. The report investigates migration in the context of demographic changes and trends in both growth and inequality. It also presents more detailed and nuanced individual;; family and village experiences;; and explores less visible movements typically pursued by disadvantaged groups such as short term and seasonal migration.

The 2010 Report continues the tradition of pushing the frontiers of development thinking. For the first time since 1990;; the Report looks back rigorously at the past several decades and identifies often surprising trends and patterns with important lessons for the future. These varied pathways to human development show that there is no single formula for sustainable progress—and that impressive long-term gains can and have been achieved even without consistent economic growth. Looking beyond 2010;; this Report surveys critical aspects of human development;; from political freedoms and empowerment to sustainability and human security;; and outlines a broader agenda for research and policies to respond to these challenges.

The 2011 Human Development Report argues that the urgent global challenges of sustainability and equity must be addressed together – and identifies policies on the national and global level that could spur mutually reinforcing progress towards these interlinked goals. Past Reports have shown that living standards in most countries have been rising - and converging - for several decades now. Yet the 2011 Report projects a disturbing reversal of those trends if environmental deterioration and social inequalities continue to intensify;; with the least developed countries diverging downwards from global patterns of progress by 2050. The Report shows further how the world's most disadvantaged people suffer the most from environmental degradation;; including in their immediate personal environment;; and disproportionately lack political power;; making it all the harder for the world community to reach agreement on needed global policy changes. The Report also outlines great potential for positive synergies in the quest for greater equality and sustainability;; especially at the national level. The Report further emphasizes the human right to a healthy environment;; the importance of integrating social equity into environmental policies;; and the critical importance of public participation and official accountability. The 2011 Report concludes with a call for bold new approaches to global development financing and environmental controls;; arguing that these measures are both essential and feasible.

The 21st century is witnessing a profound shift in global dynamics;; driven by the fast-rising new powers of the developing world. China has overtaken Japan as the world's second biggest economy;; lifting hundreds of millions of people out of poverty in the process. India is reshaping its future with new entrepreneurial creativity and social policy innovation. Brazil is raising its living standards by expanding international relationships and antipoverty programmes that are emulated worldwide. But the “Rise of the South” is a much larger phenomenon. Indonesia;; Mexico;; South Africa;; Thailand;; Turkey and other developing countries are becoming leading actors on the world stage. The 2013 Human Development Report identifies more than 40 developing countries that have done better than expected in human development in recent decades;; with their progress accelerating markedly over the past 10 years.

An estimated 3 % of the global population;; or 185 million people consume illicit drugs annually. Among this population are people from almost every country on earth and from every walk of life. Countless more people;; around the world;; are involved in the production and trafficking of illicit drugs;; and still more are touched by the devastating social and economic costs of this trade. These people live in both developed and developing countries;; are rich and poor;; healthy and unhealthy;; citizens and refugees. Illicit drugs are a truly global phenomenon. Partially a consequence of this pervasiveness;; and partially a consequence of the illicit and hidden nature of this trade;; reliable analysis and statistics on the production;; trafficking and consumption of illicit drugs are rare. In cooperation with Member States;; the United Nations Office on Drugs and Crime (UNODC) has endeavoured to fill the gaps. In this first edition of the new two volume World Drug Report;; UNODC presents more quantitative data than ever before in an effort to increase the amount of factual evidence available in a field which is so notoriously difficult to quantify. This year;; the analysis of trends;; some going back ten years or more;; is presented in Volume 1. Detailed statistics are presented in Volume 2. Taken together these volumes will provide the most complete picture yet on today's illicit drug situation.

The negative impacts of the illicit drug trade touch every society in the world. This year's World Drug Report estimates that 200 million people;; or 5% of the global population age 15-64;; have consumed illicit drugs at least once in the last 12 months. The drug trade is pernicious and large. UNODC estimates its retail value at US$ 321bn. It impacts almost every level of human security from individual health;; to safety and social welfare. Its consequences are especially devastating for countries with limited resources available to fight against it. The World Drug Report 2005 provides one of the most comprehensive overviews of illicit drug trends at the international level. In addition;; this year it presents the work of UNODC in two new areas of research. Both aim to provide tools to enrich our understanding of an immensely complex situation: an estimate of the financial value of the world drug market;; and the preliminary steps towards the creation of an illicit drug index. The analysis of trends;; some going back 10 years or more;; is presented in Volume 1. Detailed statistics are presented in Volume 2. Taken together these volumes provide the most up to date view of today's illicit drug situation.
