Social exclusion in the context of "Urban planning"

South Asia is the southern subregion of Asia that is defined in both geographical and ethnic-cultural terms. South Asia, with a population of 2.04 billion, contains a quarter (25%) of the world's population. As commonly conceptualised, the modern states of South Asia include Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka, with Afghanistan also often included, which may otherwise be classified as part of Central Asia. South Asia borders East Asia to the northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Apart from Southeast Asia, Maritime South Asia is the only subregion of Asia that lies partly within the Southern Hemisphere. The British Indian Ocean Territory and two out of 26 atolls of the Maldives in South Asia lie entirely within the Southern Hemisphere. Topographically, it is dominated by the Indian subcontinent and is bounded by the Indian Ocean in the south, and the Himalayas, Karakoram, and Pamir Mountains in the north.

Settled life emerged on the Indian subcontinent in the western margins of the Indus River Basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By 1200 BCE, an archaic form of Sanskrit, an Indo-European language, had diffused into India from the northwest, with the Dravidian languages being supplanted in the northern and western regions. By 400 BCE, stratification and exclusion by caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity.

A caste is a fixed social group into which an individual is born within a particular system of social stratification: a caste system. Within such a system, individuals are expected to marry exclusively within the same caste (endogamy), follow lifestyles often linked to a particular occupation, hold a ritual status observed within a hierarchy, and interact with others based on cultural notions of exclusion, with certain castes considered as either more pure or more polluted than others. The term "caste" is also applied to morphological groupings in eusocial insects such as ants, bees, and termites.

The paradigmatic ethnographic example of caste is the division of India's Hindu society into rigid social groups. Its roots lie in South Asia's ancient history and it still exists; however, the economic significance of the caste system in India seems to be declining as a result of urbanisation and affirmative action programs. A subject of much scholarship by sociologists and anthropologists, the Hindu caste system is sometimes used as an analogical basis for the study of caste-like social divisions existing outside Hinduism and India. In colonial Spanish America, mixed-race castas were a category within the Hispanic sector but the social order was otherwise fluid.

Climate change vulnerability is a concept that describes how strongly people or ecosystems are likely to be affected by climate change. Its formal definition is the "propensity or predisposition to be adversely affected" by climate change. It can apply to humans and also to natural systems (or ecosystems). Issues around the capacity to cope and adapt are also part of this concept. Vulnerability is a component of climate risk. It differs within communities and also across societies, regions, and countries. It can increase or decrease over time. Vulnerability is generally a bigger problem for people in low-income countries than for those in high-income countries.

Higher levels of vulnerability will be found in densely populated areas, in particular those affected by poverty, poor governance, and/or conflict. Also, some livelihoods are more sensitive to the effects of climate change than others. Smallholder farming, pastoralism, and fishing are livelihoods that may be especially vulnerable. Further drivers for vulnerability are unsustainable land and ocean use, marginalization, and historical and ongoing patterns of inequity and poor governance.

Environmental racism, ecological racism, or ecological apartheid is a form of racism leading to negative environmental outcomes such as landfills, incinerators, and hazardous waste disposal disproportionately impacting communities of color, violating substantive equality. Internationally, it is also associated with extractivism, which places the environmental burdens of mining, oil extraction, and industrial agriculture upon indigenous peoples and poorer nations largely inhabited by people of color.

Environmental racism is the disproportionate impact of environmental hazards, pollution, and ecological degradation experienced by marginalized communities, as well as those of people of color. Environmental racism is embedded in policy making- both domestically and internationally- and is a pertinent example of structural racism which consequently produces health hierarchies. It is imperative to also note the intersection of environmental racism with sexism: the vulnerabilities faced by marginalised women and gender minority groups as a result of existing health inequities are exacerbated by the consequences of environmental racism. In the United States, some communities are continuously polluted while the government gives little to no attention. According to Robert D. Bullard, father of environmental justice, environmental regulations are not equally benefiting all of society; people of color (African Americans, Latinos, Asians, Pacific Islanders, and Native Americans) are disproportionately harmed by industrial toxins in their jobs and their neighborhoods. Within this context, understanding the intersectionality of race, socio-economic status, and environmental injustice through its history and the disproportionate impact is a starting point for leaning towards equitable solutions for environmental justice for all segments of society. Exploring the historical roots, impacts of environmental racism, governmental actions, grassroots efforts, and possible remedies can serve as a foundation for addressing this issue effectively.

National security, or national defence (national defense in American English), is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, such as the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other states, action by violent non-state actors, by narcotic cartels, organized crime, by multinational corporations, and also the effects of natural disasters.

Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a state. They may also act to build the conditions of security regionally and internationally by reducing transnational causes of insecurity, such as climate change, economic inequality, political exclusion, and nuclear proliferation.

Political correctness (adjectivally "politically correct"; commonly abbreviated to P.C.) is a term used to describe language, policies, or measures that are intended to avoid perceived offense or disadvantage to members of particular groups in society. Since the late 1980s, the term has been used to describe a preference for inclusive language and avoidance of language or behavior that can be seen as excluding, marginalizing, or insulting to groups of people disadvantaged or discriminated against, particularly groups defined by ethnicity, sex, gender, sexual orientation, or disability. In public discourse and the media, the term’s use is generally pejorative, with an implication that these policies are excessive or unwarranted. It can also be humorous, or ironic in nature.

The phrase politically correct first appeared in the 1930s, when it was used to describe dogmatic adherence to ideology in totalitarian regimes, such as Nazi Germany and Soviet Russia. Early usage of the term politically correct by leftists in the 1970s and 1980s was as self-critical satire; usage was ironic, rather than a name for a serious political movement. It was considered an in-joke among leftists used to satirise those who were too rigid in their adherence to political orthodoxy. The modern pejorative usage of the term emerged from conservative criticism of the New Left in the late 20th century, with many describing it as a form of censorship.

Intellectual giftedness is an intellectual ability significantly higher than average and is also known as high potential. It is a characteristic of children, variously defined, that motivates differences in school programming. It is thought to persist as a trait into adult life, with various consequences studied in longitudinal studies of giftedness over the last century. These consequences sometimes include stigmatizing and social exclusion. There is no generally agreed definition of giftedness for either children or adults, but most school placement decisions and most longitudinal studies over the course of individual lives have followed people with IQs in the top 2.5 percent of the population—that is, IQs above 130. Definitions of giftedness also vary across cultures.

The various definitions of intellectual giftedness include either general high ability or specific abilities. For example, by some definitions, an intellectually gifted person may have a striking talent for mathematics without equally strong language skills. In particular, the relationship between artistic ability or musical ability and the high academic ability usually associated with high IQ scores is still being explored, with some authors referring to all of those forms of high ability as "giftedness", while other authors distinguish "giftedness" from "talent". There is still much controversy and much research on the topic of how adult performance unfolds from trait differences in childhood, and what educational and other supports best help the development of adult giftedness.

In its broadest sense, social vulnerability is one dimension of vulnerability to multiple stressors and shocks, including abuse, social exclusion and natural hazards. Social vulnerability refers to the inability of people, organizations, and societies to withstand adverse impacts from multiple stressors to which they are exposed. These impacts are due in part to characteristics inherent in social interactions, institutions, and systems of cultural values.

Social vulnerability is an interdisciplinary topic that connects social, health, and environmental fields of study. As it captures the susceptibility of a system or an individual to respond to external stressors like pandemics or natural disasters, many studies of social vulnerability are found in risk management literature.
