Human development (economics)

Sustainable development is an approach to growth and human development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. The aim is to have a society where living conditions and resources meet human needs without undermining planetary integrity. Sustainable development aims to balance the needs of the economy, environment, and society. The Brundtland Report in 1987 helped to make the concept of sustainable development better known.

Sustainable development overlaps with the idea of sustainability which is a normative concept. UNESCO formulated a distinction between the two concepts as follows: "Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it."

Human population projections are attempts to extrapolate how human populations will change in the future. These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. Models of population growth take trends in human development and apply projections into the future. These models use trend-based-assumptions about how populations will respond to economic, social and technological forces to understand how they will affect fertility and mortality, and thus population growth.

The 2022 projections from the United Nations Population Division (chart #1) show that annual world population growth peaked at 2.3% per year in 1963, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and could drop even further to minus 0.1% by 2100. Based on this, the UN projected that the world population, 8 billion as of 2023, would peak around the year 2084 at about 10.3 billion, and then start a slow decline, assuming a continuing decrease in the global average fertility rate from 2.5 births per woman during the 2015–2020 period to 1.8 by the year 2100 (the medium-variant projection).

International development or global development is a broad concept denoting the idea that societies and countries have differing levels of economic or human development on an international scale. It is the basis for international classifications such as developed country, developing country and least developed country, and for a field of practice and research that in various ways engages with international development processes. There are, however, many schools of thought and conventions regarding which are the exact features constituting the "development" of a country.

Historically, development was largely synonymous with economic development, and especially its convenient but flawed quantification (see parable of the broken window) through readily gathered (for developed countries) or estimated monetary proxies (estimated for severely undeveloped or isolationist countries) such as gross domestic product (GDP), often viewed alongside actuarial measures such as life expectancy. More recently, writers and practitioners have begun to discuss development in the more holistic and multi-disciplinary sense of human development. Other related concepts are, for instance, competitiveness, quality of life or subjective well-being.

The United Nations Development Programme (UNDP) is a United Nations agency tasked with helping countries eliminate poverty and achieve sustainable economic growth and human development. The UNDP emphasizes on developing local capacity towards long-term self-sufficiency and prosperity.

Based at the headquarters of the United Nations in New York City, it is the largest UN development aid agency, with offices in 177 countries. The UNDP is funded entirely by voluntary contributions from UN member states.

The politics of climate change results from different perspectives on how to respond to climate change. Global warming is driven largely by the emissions of greenhouse gases due to human activity, especially the burning of fossil fuels, certain industries like cement and steel production, and land use for agriculture and forestry. Since the Industrial Revolution, fossil fuels have provided the main source of energy for economic and technological development. The centrality of fossil fuels and other carbon-intensive industries has resulted in much resistance to climate policy, despite widespread scientific consensus that such policy is necessary.

Climate change first emerged as a political issue in the 1970s. Efforts to mitigate climate change have been prominent on the international political agenda since the 1990s, and are also increasingly addressed at national and local level. Climate change is a complex global problem. Greenhouse gas (GHG) emissions contribute to global warming across the world, regardless of where the emissions originate. Yet the impact of global warming varies widely depending on how vulnerable a location or economy is to its effects. Global warming is on the whole having negative impact, which is predicted to worsen as heating increases. Ability to benefit from both fossil fuels and renewable energy vary substantially from nation to nation.

The United Nations Development Programme (UNDP) compiles the Human Development Index (HDI) of 193 nations in the annual Human Development Report. The index considers the health, education, income and living conditions in a given country to provide a measure of human development which is comparable between countries and over time.

The HDI is the most widely used indicator of human development and has changed how people view the concept. However, several aspects of the index have received criticism. Some scholars have criticized how the factors are weighed, in particular how an additional year of life expectancy is valued differently between countries; and the limited factors it considers, noting the omission of factors such as the levels of distributional and gender inequality. In response to the former, the UNDP introduced the inequality-adjusted Human Development Index (IHDI) in its 2010 report, and in response to the latter the Gender Development Index (GDI) was introduced in the 1995 report. Others have criticized the perceived oversimplification of using a single number per country.

Degrowth is an academic and social movement aimed at the planned and democratic reduction of production and consumption as a solution to social-ecological crises. Commonly cited policy goals of degrowth include reducing the environmental impact of human activities, redistributing income and wealth within and between countries, and encouraging a shift from materialistic values to a convivial and participatory society. According to degrowth theorists, degrowth is a multi-layered concept that combines critiques of capitalism, colonialism, patriarchy, productivism, and utilitarianism, while envisioning more caring, just, convivial, happy, and democratic societies.

Degrowth is critical of the concept of growth in gross domestic product as a measure of human and economic development. It argues that modern capitalism's unitary focus on growth causes widespread ecological damage and is unnecessary for the further increase of human living standards.
