"UNDP is the UN's global development network, an organization advocating for change and connecting countries to knowledge, experience and resources to help people build a better life. We are on the ground in 166 countries, working with them on their own solutions to global and national development challenges. As they develop local capacity, they draw on the people of UNDP and our wide range of partners."
Mission
"The Division for
Sustainable Development provides leadership and is an authoritative
source of expertise within the United Nations system on sustainable
development. It promotes sustainable development as the substantive
secretariat to the UN Commission on Sustainable Development (CSD) and
through technical cooperation and capacity building at international,
regional and national levels. The context for the Division's work is
the implementation of Agenda 21, the Johannesburg Plan of
Implementation and the Barbados Programme of Action for Sustainable
Development of Small Island Developing States."

"Secretary-General Kofi Annan has identified five themes for particular
attention at the Summit: water, energy, health, agriculture and
biodiversity. These are critical areas for long-term development,
involving complex interactions among economic, social and environmental
factors and involving different sectors, organizations and disciplines.
Those issues, together with population and poverty, and the
relationships among them, are the focus of the material collected here."
Population and Carrying Capacity

Natural Capital Depletion

The Population Division is responsible for monitoring and appraisal of the broad range of areas in the field of population. To carry out this responsibility it:
• provides support and servicing of such intergovernmental bodies as the Commission on Population and Development, as well as related work of the General Assembly and the Economic and Social Council, through the preparation of high-quality documentation, analytical work and facilitation of consensus-building and policy development. It supports the implementation of the recommendations in the Programme of Action adopted by the International Conference on Population and Development, including monitoring progress towards the achievement of the goals set out in the Programme of Action, as well as identifying, analyzing and investigating policy issues and salient global trends in the field of population and development.
• facilitates access by Governments to information on population trends and their interrelationships with social and economic development as an input to government policy and programme formulation. The official United Nations demographic estimates and projections are prepared for all countries and areas of the world, as well as urban and rural areas and major cities, and serve as the standard and consistent set of population figures for use throughout the United Nations system. International migration, infant, child and maternal mortality and increased adult mortality in some regions, as well as the demographic impact of AIDS, are critical emerging issues that are also addressed. Other priority areas for analysis are fertility levels, trends and their determinants, including contraceptive use as well as national population policies and the relationships among population dynamics and development issues.
• contributes to the capacity building of Member States to formulate national population and related policies and programmes for the effective implementation of the recommendations of the Programme of Action; and improves the institutional capabilities of Governments for the collection, analysis and distribution of national population information.
• enhances coordination and cooperation among the organizations of the United Nations system through the Administrative Consultative Committee Subcommittee on Demographic Estimates and Projections and between the United Nations system and other international, regional and national organizations active in the field of population.
• distributes electronic population information in response to requests and to support coordination among the United Nations entities in the field of population.
United Nations System-wide Earthwatch (new window, website):: Exceeding carrying capacity (new
window, webpage)
Some of the worst humanitarian crises
since Rio, in countries like Haiti, Rwanda and Somalia, share as
underlying causes, behind obvious political and ethnic divisions, a
high and rapidly increasing density of population, extreme poverty, and
a shortage of essential environmental resources, in particular a drop
in per capita food production. These may be some of the first
illustrations of the consequences of exceeding the environmental
capacity of a country or region (Mathews, 1994; Atwood, 1994). The
increase in environmental
refugees who leave their homes because local resources can no longer
support them is another symptom of this problem. The International
Conference on Population and Development in Cairo in 1994 recognized
the need to integrate population, environmental and poverty eradication
factors in sustainable development policies, plans and programmes (UN,
1994b).

discussed in the section Models (above) under World3 subsection. The
readers are invited to obtain a copy of the model and run it for
themselves - instructions are provided in that subsection.

Overshoot
The following are characteristics of a society that has grown beyond
its limits—a society that is drawing upon the earth's resources
faster than they can be restored, and that is releasing wastes and
pollutants faster than the earth can absorb them or render them
harmless.

The International Institute for Sustainable Development contributes to sustainable development by advancing policy recommendations on international trade and investment, economic policy, climate change, measurement and assessment, and natural resources management. By using Internet communications, we report on international negotiations and broker knowledge gained through collaborative projects with global partners, resulting in more rigorous research, capacity building in developing countries and better dialogue between North and South.
Carrying
Capacity (new window,
website)
Concept
Human life depends on healthy ecosystems which supply life-sustaining resources and absorb wastes. However, current growth and consumption patterns are placing increasing stress on ecosystems. Environmental degradation, biodiversity loss, deforestation, and the breakdown of social and economic systems are a few of the signs which indicate that ecosystems are stressed.
Ecosystems threatened by overharvesting and/or overwhelmed by more
wastes than can be absorbed lose resilience (ie. the ability to absorb
shocks and disturbances) and may suddenly break down and/or settle into
a different system with less reilience. This implies there are
thresholds at which the levels of stress will lead to the disruption of
the system. One concept used to understand these critical limits and
thresholds is carrying capacity which assumes that there are a finite
number of people who can be supported without degrading the natural
environment and social, economic and cultural systems and, as such, "is
an indirect measure of the maximum level of stress that the ecosystem
can maintain". ( Barbier, Burgess and Folke 1994).

There are many signs of
climate change
• Global average surface temperatures have increased
by about 0.6°C since 1900.
• Sea levels are rising by about 1 cm per decade.
• Arctic sea ice thickness has declined 40 per cent in
the past 40 years.
• Major glaciers throughout the world are retreating.
• Lake ice is forming later in the autumn and melting earlier in the
spring.
• Precipitation in the Northern Hemisphere has increased, particularly
as intense rainfall.
• El Niño events have become more common and more intense.
• In parts of Asia and Africa, droughts have increased in frequency and
intensity.
• Insurance payments for damage from floods and storms increased from
about $2 billion annually in the 1980s
to $30 billion annually in the early 1990s.

IGBP is an international scientific research programme built on
interdisciplinarity, networking and integration. It addresses
scientific questions where an international approach is the best or the
only way to provide an answer. We add value to a large number of
individual, national and regional research projects through integrating
activities to achieve enhanced scientific understanding.

Global Change and the Earth System: a
Planet Under Pressure
Editors: Will Steffen and Peter Tyson
The
Earth as a system
The fact that the Earth behaves as a single, interlinked,
self-regulating system was put into dramatic focus in 1999 with the
publication of the 420,000-year record from the Vostok ice core
(Fig.1). These data, arguably among the most important produced by the
scientific community in the 20th century, provide a powerful temporal
context and dramatic visual evidence for an integrated planetary
environmental system.
The Vostok ice core data give a
wealth of insights into the Earth System. Three striking
characteristics demonstrate beyond any doubt that the Earth is a
system, with properties and behaviour that are characteristic of the
System as a whole.
This systemic behaviour of Earth's
environment is due to a combination of external forcing – primarily
variations in solar radiation levels near the Earth's surface – and a
large and complex array of feedbacks and forcings within Earth's
environment itself. The internal dynamics of the System, rather than
external forcings, undoubtedly keep the planet habitable for life.
Mandate and Membership of the IPCC
Recognizing the problem of potential global climate change, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) established the Intergovernmental Panel on Climate Change (IPCC) in 1988. It is open to all members of the UN and WMO.
The role of the
IPCC is to assess on a comprehensive, objective, open and transparent
basis the scientific, technical and socio-economic information relevant
to understanding the scientific basis of risk of human-induced climate
change, its potential impacts and options for adaptation and
mitigation. The IPCC does not carry out research nor does it monitor
climate related data or other relevant parameters. It bases its
assessment mainly on peer reviewed and published scientific/technical
literature. Its role, organisation, participation and general
procedures are laid down in the "Principles
Governing IPCC Work"

"Natural, technical, and social
sciences can provide essential information and evidence needed for
decisions on what constitutes “dangerous anthropogenic interference
with the climate system.” At the same time, such decisions are value
judgments determined through socio-political processes, taking into
account considerations such as development, equity, and sustainability,
as well as uncertainties and risk.
The basis for determining what constitutes
“dangerous anthropogenic interference” will vary among
regions—depending both on the local nature and consequences of climate
change impacts, and also on the adaptive capacity available to cope
with climate change—and depends upon mitigative capacity, since the
magnitude and the rate of change are both important. There is no
universally applicable best set of policies; rather, it is important to
consider both the robustness of different policy measures against a
range of possible future worlds, and the degree to which such
climate-specific policies can be integrated with broader sustainable
development policies.
The Third Assessment
Report (TAR) provides an assessment of new scientific information and
evidence as an input for policymakers in their determination of what
constitutes “dangerous anthropogenic interference with the climate
system.” It provides, first, new projections of future concentrations
of greenhouse gases in the atmosphere, global and regional patterns of
changes and rates of change in temperature, precipitation, and sea
level, and changes in extreme climate events. It also examines
possibilities for abrupt and irreversible changes in ocean circulation
and the major ice sheets. Second, it provides an assessment of the
biophysical and socio-economic impacts of climate change, with regard
to risks to unique and threatened systems, risks associated with
extreme weather events, the distribution of impacts, aggregate impacts,
and risks of large-scale, high-impact events. Third, it provides an
assessment of the potential for achieving a broad range of levels of
greenhouse gas concentrations in the atmosphere through mitigation, and
information about how adaptation can reduce vulnerability."

Summary for Policymakers
1. Carbon dioxide (CO2) capture and storage (CCS) is a process
consisting of the separation of CO2 from industrial and energy-related
sources, transport to a storage location and long-term isolation from
the atmosphere. This report considers CCS as an option in the portfolio
of mitigation actions for stabilization of atmospheric greenhouse gas
concentrations.

Overview of
CO2 emission sources, potential, transport and geographical

Abstract
Capture and storage of CO2 has the potential, when used in combination
with other mitigation options, to make deep reductions in greenhouse
gas emissions. Geological storage is the preferred storage option
because the reservoirs potentially have sufficient storage capacity to
hold the required volumes of CO2. Any capture and storage project
involves three distinct phases; capture of the CO2 from the emission
source, dehydration followed by compression and transportation of CO2
and finally injection of CO2 into reservoirs at the storage site. To
develop an understanding of the real potential of CO2 capture and
storage for reducing CO2 emissions worldwide it is necessary to gain an
awareness of the geographical distribution of the CO2 emissions and the
storage reservoirs. Once the geographical relationship between sources
and storage reservoirs is clear then transportation networks for the
CO2 can be considered. This paper will review research activities
underway worldwide that are developing the understanding of the
geographical relationship between emission and storage site mapping,
appraise the status of the work and indicate where additional work is
needed to close any gaps in our understanding.

The European Topic Centre of Resource and Waste Management (ETC/RWM) understand natural resources to cover both renewable resources and non-renewable resources. These can be further split into four categories:
Three generic management principles for the sustainable use of natural resources were established by political institutions following Rio during the 1990s. These are:
Use of renewables as referred to by principle 3 above, is these days taken to include the full life-cycle of the resource use or material flow. That life cycle includes extraction from the environment, processing, transformation utilisation and disposal. Outputs of substances include the release of all resulting residuals (e.g. waste, emissions, heat) back to the environment during all these life cycle stages.
