Overview:
This is the 2008 draft synopsis of global challenges. You will get the newest version of the synopsis here.
This survey gives an overview of the most urgent global challenges for human needs and life. All these challenges are of existential importance for human life, since these challenges are concerned with overcoming or reducing to the extent possible the large-scale damages and/or risks that affect many people. The addressed challenges mainly originate in man-made influences, but to the lesser extent in the individual behaviour of the affected people, instead the challenges are more due to larger-scale human activities.
The global challenges have been weighed and prioritized as far as available data and risk assessments allow. They are considered with regard to the questions: Are they paid enough attention? Are efforts taken that are needed to overcome them? For selecting and weighing the challenges indicators are used which relate to damages and risks to life and health, to economic and social development, and to natural foundations of human life. Data, risk assessments, goals, targets and recommended measures are all taken from trusted sources such as scientific institutions,
In order to avoid misconceptions, it should be pointed out that the survey does not aspire to give a complete description of all global challenges or the state of the world. Instead only the most urgent challenges shall be identified. By no means does this claim that further challenges are irrelevant or negligible. Furthermore, this survey on most urgent challenges does not rate different countries or groups of countries as high or low, but rather takes a global perspective.
Within this synopsis the various connections between, and overlapping of, the global challenges can only be indicated. They are described more precisely in the separate pages on the specific global challenges.
Although many of these challenges seem to be too burdensome for people to become involved in, progress can be seen and some other severe problems have already been solved. Every progress in terms of saving human lives, improving health and other bases of our existence is worth the effort.

Although there is enough food to feed every person on the planet, 963 million people suffer from chronic hunger (increasing). Roughly almost five million per year die, among them 3.5 million children under 5 (decreasing). The highest death toll of the worst famines in human history were claimed between 20 and 40 million lives. Extreme poverty is one of the main causes, affecting the 1.4 billion people living below 1.25 dollar per day (rising). The members of the United Nations have agreed upon the targets of halving the proportions of undernourished and of extreme poor people from 1990 to 2015. In order to reach the nutrition target 30 billion

About 33 million people suffer from / (increasing). Circa 14.4 million people are sick from tuberculosis (rising), 247 million from malaria. Together, these diseases kill around 4.3 million people per year. There are also global risks of resistant germs and new diseases, characterized by a very large damage potential as well as uncertain probabilities of occurrence. In our time, an event similar to the 1918 Spanish flu pandemic could result in over 100 million deaths. The UN targets to halt the spread of HIV/AIDS, malaria, and other major infectious diseases by 2015. Information and antiretroviral therapy against HIV/AIDS need at least 20 billion $ in 2009. Further measures consist of anti-malaria bed nets, insecticide use and new treatments.

About 39% of deliveries in countries of the South take place without assistance by skilled attendants (decreasing). Furthermore, 300 million women are suffering from illness brought about by pregnancy or childbirth. Every year there are between 3.7 and 4.5 million infant and maternal deaths. The UN members have set the targets of reducing the mortality rate of children under the age of 5 by two thirds and the maternal mortality rate by three quarters from 1990 to 2015. Furthermore universal access to reproductive health and family planning shall be achieved. Comprehensive measures to reduce child mortality would require 52.4 billion $.

Each year, 1.5 million people – primarily women and children – die due to respiratory diseases resulting from indoor air pollution (decreasing). This is due to cooking inside with an open fire; the underlying cause can be seen as predominantly a lack of access to modern energy. Three billion people live in such households. The WHO air quality guideline for respirable particulate matter with a diameter less than 10 µm (PM10) applies also to indoor air pollution. Interventions are more efficiently vented stoves or rooms, and cleaner fuels. Appropriate stoves for all affected households would cost about 30 billion $. 112 governmental and non-governmental actors have joined in the Partnership for Clean Indoor Air.
(WHO 2007 and 2002, 69, 226; WHO 2002, 70; WHO 2006, 10; 2003.)
About 24.3 million people are injured or disabled, and 1.28 million people die in road traffic per year. The global economic costs of road crashes have been estimated at $ 518 billion annually. There is no international target. Measures: safe road design, traffic management, seat belts, helmets, day-time running lights, speed limits, and restrictions on drinking and driving.
(WHO 2008a, 28, 58 and 117; WHO 2003, 96; WHO 2002, 72.)
About 879 million people do not have access to hygienic water and 2.5 billion are missing basic water sanitation (both decreasing). As a result this leads to 4.6 billion cases of disease as well as to 1.63 million deaths annually, most of them children. The UN members agreed to halve, from 1990 to 2015, the proportion of people lacking access to safe drinking water, as well as the proportion of those having no access to basic sanitation. To achieve the targets, 10 billion $ per year are needed. Measures range from disinfection at the point of consumption up to rainwater collection and household connections to water.

There are about 268 million occupational accidents and 160 million victims of work-related illnesses per year. Annually, 2.2 million people die by work-related diseases or accidents. There is no international target. Occupational cancers are entirely preventable through hygiene measures, substitution of safer materials, enclosure of processes, and ventilation.
( 2005, 3, 7 and 1; WHO 2002, 75.)
Between 172 000 and 310 000 people per year are killed by violence in recent armed conflicts (decreasing). Within the 20th century, there were about 191 million deaths in armed conflicts. Since armament started to include weapons of mass destruction we are confronted with the danger of man-made devastation on mankind. Production and storage of

Soils deliver more than nine tenths of all food. More than 1.2 billion people and about one third of all land usable for agriculture in more than 110 countries are affected by soil degradation. Moreover large areas are threatened with being turned into steppe or deserts. Major causes are overgrazing, intensive or inappropriate methods of agriculture, and deforestation. Suitable plantings can improve the quality of soils. The UN has agreed on the goal to combat desertification and mitigate the effects of drought.
(MA 2005a; UNCCD 1994; unccd.int.)
Annually, 521 million people are exposed to floods, 344 million to tropical cyclones, 130 million to meteorological drought and 118 million to major earthquakes. From 1998 to 2007, 113 000 died on average per year by disasters with a natural or technological trigger. In 2008 more than 220 000 people died as a result of natural disasters. The deadliest natural disaster in recorded history, the flood of the Huang He (Yellow river), has caused 850 000 to 4 million casualties. Economic losses by natural catastrophes totalled some 200 billion $ in 2007. Since the fifties annual losses from natural catastrophes have increased tenfold. While there is no international target, the UN has started the International Strategy for Disaster Reduction with the goal of reducing human, social, economic and environmental losses due to natural hazards and related technological and environmental disasters. A framework for action from 2005 to 2015 has been developed, which is concerned

More than 1.2 billion people live in areas of physical water scarcity, lacking enough water for food production, health, and development (increasing). Between 5% and 25% of global freshwater use likely exceeds long-term accessible supply. Water quality, on global average, is declining, too. This issue raises the risk of conflicts. The UN members have agreed to stop the unsustainable exploitation of water resources by developing water management strategies. The Global Water Partnership supports their implementation.

Since 1970 financial crises have increased and caused fiscal costs in the 1980s and 1990s of more than 1 trillion $. In 2007/08 the worst crisis since 1929 has occured. Losses are 2.8 trillion $ (5% of global

Between 501 000 and 1.3 million deaths are caused by unsafe injection practices in medical settings per year. Reuse of injection equipment without sterilization leads annually to 8 to 20.6 million cases of new hepatitis B infections, 2.0 to 4.7 million cases of hepatitis C infections and 80 000 to 260 000 cases of HIV infections. This may cost more than 535 million $ per year in direct medical expenditures. There is currently no international target. Measures include the communication of risks associated with unsafe injections to patients and health care workers as well as ensuring access to sufficient quantities and quality of injection equipment in health care facilities.
(WHO 2008, 44, 2004, 1831, and 2002, 78; Miller/Pisani 1999, 808f.; WHO 2004a, 1831; Kane et al. 1999, 803; WHO 2008, 44, Miller/Pisani 1999, 808f.; WHO 2004a, 1840, and 2002, 130f.)
Twelve of the fourteen indicators for biodiversity, which is important for ecosystem stability, show a negative trend. The Living Planet Index points out a decline of species abundance of about 28% since 1970. The worth of benefits from biodiversity, for example a successful pharmacological product, can amount to 50-100 billion $. The global risks of ecosystem destabilization and anthropogenic affects on mass developments of species have a high potential for damage, with high resp. unknown probabilities of occurrence. The UN members target to reduce the rate of loss of biodiversity significantly by 2010. Measures include: establishing more, as well as improving, protected areas; using more environmentally sound methods in agriculture; storing seeds and genes; and protecting species threatened by extinction.

Deforestation has heightened the risk of malaria in Africa and South America by increasing the habitable environments for mosquitoes that transmit malaria. Each year 18% to 25% of greenhouse gas emissions are due to deforestation. The net loss of forests has decreased in the last years to 7.3 million hectares annually. Deforestation contributes to biodiversity loss. Each year illegal logging causes losses in assets, revenue and royalties of more than 15 billion $. The UN strives to reverse the loss of forest cover worldwide by sustainable forest management. Trading of illegally harvested timber has to be supervised and restricted. Poverty reduction, soil protection, and access to modern energy can open up alternatives to depletion.

Global resource extraction is 55 billion tonnes (increasing). Maintaining resource supply depends on whether the success in exploration for and extraction of deposits that are currently uneconomic or unknown will be continued or increased beyond next decades. The material flow, energy use and pollution caused by resource extraction will likely rise. In the early 2010s production of oil will not meet the demand. The assumed onset of a maximum in oil extraction ranges from 2005 to 2020 (or, including non-conventional oil, not before 2030). Subsequent oil supply disruptions could cost the US economy alone about 4 trillion $.

Safe technologies are, for example, renewable energies, recycling-based economy, bionics, etc. High risk technologies include: (1) nuclear power, large chemical facilities, and dams (potential for very extensive damage with a very low probability of occurrence), (2) certain genetic engineering applications (potential for very extensive damage but unknown probability), and last but not least, (3) any climate damaging technology. The three most severe accidents by such risk technologies have caused about 32 500 to 442 500 deaths in total. Nanotechnologies need ongoing assessment. The UN has addressed technological risks. Measures consist of: support of research, development and market launch of safe technologies, research on risks, regulation and reduction of technological risks, including the option of prohibition.

Damage to the ozone layer by fluorinated hydrocarbons has already been considerably reduced by measures undertaken even before the damaging effect could be clearly proved by science. This is a success story for the application of the precautionary principle. Nevertheless, there are still risks of heightened ultraviolet radiation and the associated increase of skin cancer. The recovery of the ozone layer is not expected until the mid-21st century. Stopping production and use of ozone depleting substances (CFCs and FCs) has been achieved to more than 90%. There are still problems with regard to some substitutes, CFCs produced and traded illegally, and the management of stockpiles.

Challenges on capacity building:
In order to overcome the global challenges several capacities for action can be used or built up, which can contribute to practical progress: (1) cooperation in partnerships by persons and/or institutions, enterprises or organizations; (2) civic commitments of people or the "corporate citizenship" of enterprises or institutions; (3) options for democratic participation in public affairs, including transparency and good governance. The Agenda 21 and the Millennium Declaration of the United Nations rely on the principle of cooperation. Partnerships are on the rise, and the number of parliamentary democracies is increasing as are the institutional, social and technical possibilities for participation.

Getting involved with improving conditions of life is made easier by rules and guarantees that are stipulated in universal, civic, political, economic, social, and cultural human rights. This kind of empowerment can strengthen activities, too. Gender equality, rooted in human rights, is a key to many global challenges. The UN members target to end disparities between boys and girls in all levels of education. Of the children in the less developed countries, 11% of the boys and 14% of the girls are not enrolled in primary school. The share of women in parliaments has increased from 13% to 18% globally. The share of world population assessed to be participating in a high level of political and civic rights has increased as well.

Capacity building also includes access to information and education. This enables people in understanding problems and influencing politics and markets on the base of solid information as well as choosing options concerning lifestyles. Furthermore, it assists in creating and accelerating new solutions in research and development and thereby shaping our paths to the future. Agenda 21 and the Millennium Declaration emphasize strengthening education and science along with the role of private business and information technology. The target for 2015 is that all children shall be able to complete primary schooling – to date 88% of the children in the South are enrolled in primary school (increasing). Additionally, the UN has maintained that information and communication technologies shall be available to all. Today, in the North 53% have Internet access, in the South it is only 9% (increasing). Patent activity is rising, too.

The base year of all target data is 1990, unless other stated.
Trends specified by +, 0 or − refer to the current direction of development, but not to whether the development is on track to meet a given target.
For numeric names the short scale is used:
1 billion = one thousand million = 109 = 1 000 000 000
1 trillion = one thousand billion = 1012 = 1 000 000 000 000
1 µm = 1 micrometre (micron) = 0.001 mm = 10-6 m
Almost all available data on global conditions is of low precision. Most data on the largest problems of mankind only partially relies on actual measurements of specific cases, but often on estimates based on modelling and extrapolation. So the data base is far from meeting the motto of the WHO Report 2005: Make every mother and every child count.
