23、 individual.The 2019 edition of the World Water Development Report focuses on the theme of“Leaving No One Behind”.It argues that fulfilling the human rights to safe drinking water and sanitation for all can also significantly contribute to the achievement of the broad set of goals of the 2030 Agenda
24、 for Sustainable Development:from food and energy security,to economic development and environmental sustainability.Based on the latest data,this reports findings clearly illustrate the need to make substantial progress towards delivering on the 2030 Agenda promise of reaching the most vulnerable.Th
25、e stakes are high:nearly a third of the global population do not use safely managed drinking water services and only two fifths have access to safely managed sanitation services.The intensification of environmental degradation,climate change,population growth and rapid urbanisation among other facto
26、rs also pose considerable challenges to water security.Furthermore,in an increasingly globalised world,the impact of water-related decisions cross borders and affect everyone.At the current pace of progress,billions of people will remain unable to enjoy their right to access to water and sanitation
27、and the multiple benefits that such access can provide.Yet,this report concludes these objectives are entirely achievable,so long as there is a collective will to do so,entailing new efforts to include those left behind in decision-making processes.This latest Report,coordinated by UNESCO,is the res
28、ult of a collaborative effort of the UN-Water Family and was made possible thanks to the long-standing support of the Government of Italy and the Umbria Region,to whom we are extremely grateful.I am convinced that the 2019 edition will spur action and help support Member States in making informed de

30、alls on us to transform our world and leave no one behind.The 2019 edition of the United Nations World Water Development Report demonstrates how improving the management of water resources,providing access to safe and affordable drinking water and sanitation for all contribute to the goals that unde
31、rpin the 2030 Agenda.Water for all is essential for eradicating poverty,building peaceful and prosperous societies and reducing inequality.The numbers speak for themselves.As the Report shows,if the degradation of the natural environment and the unsustainable pressure on global water resources conti
32、nue at current rates,45%of global Gross Domestic Product and 40%of global grain production will be at risk by 2050.Poor and marginalized populations will be disproportionately affected,further exacerbating already rising inequalities.The 2019 edition looks at different dimensions of inequality linke
33、d to food and nutrition,disasters and migration,drawing on data and information from the UN family and others.For example:if women had the same access as men to productive resources including land and water,they could increase yields on their farms by 20 to 30%,raising total agricultural output in t
34、hese countries by 2.5 to 4%.This could reduce the number of hungry people in the world by around 12 to 17%.Further,the overall risk of being displaced by disasters has doubled since the 1970s.The depletion of water and other natural resources is increasingly recognized as a driver of displacement th
35、at triggers internal and international migration.The 2019 Report provides evidence of the need to adapt approaches,in both policy and practice,to address the causes of exclusion and inequality.This is key to ensuring the availability and sustainable management of water and sanitation for all.To buil
36、d knowledge and inspire people to take action,UN-Water commissions UN-Water publications such as the UN World Water Development Report drawing on the experience and expertise of UN-Water Members and Partners.Thanks are due to all my colleagues,and especially to UNESCO for coordinating the production
37、 of this Report that will contribute to greater sustainability and resilience,and to creating a world where no one is left behind.Gilbert F.HoungboxThe United Nations World Water Development Report 2019PrefaceThe 2030 Agenda for Sustainable Development sets a series of ambitious challenges for the g
38、lobal community.These Sustainable Development Goals(SDGs)include targets for access to safe drinking water and sanitation and better water management,as well as goals for addressing inequality and discrimination,including the overarching aims of leaving no one behind and reaching the furthest behind
39、 first.These are challenges that,to date,have proven difficult to meet,partly because they are complex,but also due to political inertia.The global context for this agenda may be characterized as crisis is the new normal,with political insecurity,social,economic and environmental challenges on a dau
40、nting scale.This calls for redoubled efforts and carefully selected approaches towards achieving transformative change.The issues underlying both water-related goals and leaving no one behind intersect in several ways.Both water supply and sanitation,and issues of equality for all people and for spe
41、cific disadvantaged groups in particular,are recognized through international human rights instruments and agreements.However,these have not been enough to bring about the necessary changes.To some extent,the issues share both root causes and similar challenges.The same people who are being left beh
42、ind are those who could benefit most from improved access to water and sanitation.Improved access to water and sanitation,water management and governance,and the multiple benefits they bring,can contribute significantly to positive transformation for marginalized people.Benefits include better healt
43、h,savings in time and money,dignity,improved access to food and energy,and greater opportunities in terms of education,employment and livelihoods.These benefits,directly and indirectly,separately and in combination,contribute to improving the lives of all,but can be particularly transformative for p
44、eople in vulnerable situations.At the same time,engaging with marginalized groups can enhance the achievement and sustainability of water-related goals.This process of engagement can also be transformative in giving a voice to those rarely heard,in turn creating space for vital water-related knowled
45、ge and experience that might otherwise be lost.As the sixth in a series of annual,thematic reports,the 2019 edition of the United Nations World Water Development Report(WWDR)examines how improved water resource management and access to water supply and sanitation services can help address the causes
46、 and alleviate the impacts of poverty and social inequity.It provides insights and guidance in helping identify who is being left behind,and describes how existing frameworks and mandates,such as the 2030 Agenda and the SDGs and human rights-based approaches,can help reach the furthest first,through
47、 improved water management.The report assesses the issues and offers potential responses from technical,social,institutional and financial perspectives,while taking account of the many different challenges faced in rural and urban settings.With the world witnessing the highest levels of human displa
48、cement on record,an entire chapter has been dedicated to the exceptional challenges faced by refugees and forcibly displaced people with respect to water and sanitation.by Stefan Uhlenbrook,UNESCO WWAP Coordinatorand Richard Connor,Editor in Chiefxi We have endeavoured to produce a balanced,fact-bas
49、ed and neutral account of the current state of knowledge,covering the most recent developments,and highlighting the challenges and opportunities provided by improved water management in the context of human development.Although primarily targeted at national-level decision-makers and water resources
50、 managers,as well as academics and the broader development community,we hope this report will also be well received by those interested in poverty alleviation,humanitarian crises,human rights and the 2030 Agenda.This latest edition of the WWDR is the result of a concerted effort between the Chapter
