Un réfugié – au sens de la Convention du 28 juillet 1951 relative au statut des réfugiés – est une personne qui se trouve hors du pays dont elle a la nationalité ou dans lequel elle a sa résidence habituelle ; qui craint avec raison d’être persécutée du fait de son appartenance communautaire, de sa religion, de sa nationalité, de son appartenance à un certain groupe social ou de ses opinions politiques ; et qui ne peut ou ne veut se réclamer de la protection de ce pays ou y retourner en raison de ladite crainte. Les personnes essayant d'obtenir le statut de réfugié sont appelées demandeurs d'asile. Les demandes d'asile faites dans les pays industrialisés se fondent le plus souvent sur des critères et des motifs politiques et religieux. Le Haut Commissariat des Nations unies pour les réfugiés (UNHCR ou HCR dans l'espace francophone) a pour but de défendre les droits et la sécurité des réfugiés et des demandeurs d'asile. Cette organisation onusienne estime que, en 2015, il y avait 16,1 millions réfugiés dans le monde, soit 60 % de plus que la décennie présente. De son côté, l'UNRWA, une organisation qui seulement aide Palestiniens dans le Proche-Orient estime, il y avait en outre 5,2 millions réfugiés palestiniens (car l'UNRWA considère également les descendants de réfugiés comme eux-mêmes réfugiés, à la différence du HCR). Selon l'UNICEF, environ 31 millions d'enfants étaient réfugiés fin 2015, et 17 millions étaient déplacés à l'intérieur de leur pays. (fr)  +, A refugee, conventionally speaking, is a displaced person who has crossed national borders and who cannot or is unwilling to return home due to well-founded fear of persecution. Such a person may be called an asylum seeker until granted by the contracting state or the United Nations High Commissioner for Refugees (UNHCR) if they formally make a claim for asylum.The lead international agency coordinating refugee protection is the United Nations Office of the UNHCR. The United Nations has a second office for refugees, the United Nations Relief and Works Agency (UNRWA), which is solely responsible for supporting the large majority of Palestinian refugees. (en)  +
Regulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context. For example: * in biology, gene regulation and metabolic regulation allow living organisms to adapt to their environment and maintain homeostasis; * in government, typically regulation means stipulations of the delegated legislation which is drafted by subject-matter experts to enforce primary legislation; * in business, industry self-regulation occurs through self-regulatory organizations and trade associations which allow industries to set and enforce rules with less government involvement; and, * in psychology, self-regulation theory is the study of how individuals regulate their thoughts and behaviors to reach goals.

Remunicipalisation commonly refers to the return of previously privatised water supply and sanitation services to municipal authorities. It also encompasses regional or national initiatives. (en)  +
La résilience communautaire (ou résilience collective) est la capacité d'une communauté de continuer à vivre, fonctionner, se développer et s'épanouir après un traumatisme ou une catastrophe. Une communauté résiliente est un groupement de personnes structuré et organisé pour s'adapter rapidement au changement, surmonter un traumatisme, tout en maintenant sa cohésion et des relations ouvertes avec le reste du monde. Elle s'efforce d'améliorer son quotidien en tissant à nouveau du lien social, en misant davantage sur la solidarité. La résilience communautaire se veut l'application concrète du concept de résilience à l'échelle d'une communauté. L'homme est un être social, étroitement lié à son entourage, qui s'épanouit et s'organise en groupe. L'homme peut être exposé à des traumatismes d'ordre personnel (comme la perte d'un proche, la maladie), mais aussi à des événements extérieurs, qui peuvent affecter sa communauté (catastrophe naturelle, choc économique, rupture dans les réseaux d'approvisionnement, etc.). De ce fait, son autonomie au sein de la société est relative et surtout fragile. L'homme moderne est généralement dépendant des chaînes logistiques qui permettent l'approvisionnement des énergies, des biens et des services. Développer la résilience collective passe donc inévitablement par le développement de l'autonomie du groupe et par un travail de dépassement du traumatisme, au niveau personnel et collectif. La résilience individuelle est étroitement liée à une faculté de résilience collective. Un parallèle peut être fait avec le domaine de la santé : la résilience du corps ne concerne qu'un seul individu, mais dans d'autres domaines comme la traumatologie, les séquelles non organiques (psychologiques ou sociopsychologiques) se considèrent dans un contexte de relation avec l'autre. La résilience d'un couple, d'une famille, concerne bien sûr ses membres, mais aussi leur entourage et les générations à venir : les parents cherchent généralement à offrir à leurs enfants une situation qu'ils considèrent comme « meilleure » que celle qu'ils ont connue, avec des effets collectifs souvent imprévus. (fr)  , Community resilience is the sustained ability of a community to use available resources (energy, communication, transportation, food, etc.) to respond to, withstand, and recover from adverse situations (e.g. economic collapse to global catastrophic risks). This allows for the adaptation and growth of a community after disaster strikes. Communities that are resilient are able to minimize any disaster, making the return to normal life as effortless as possible. By implementing a community resilience plan, a community can come together and overcome any disaster, while rebuilding physically and economically. Due to its high complexity the discussion on resilient societies has increasingly been considered from an inter- and transdisciplinary scope. Around 2010 the French-speaking discourse coined the notion of collapsology (collapse science), discussing the resilience of societal systems and possible scenarios for societal transformations in the face of a variety of factors, such as dependence on fossil fuels, overpopulation, loss of biodiversity, and instability of the financial system. The controversial term was created by Pablo Servigne (an agricultural engineer) who, with Raphaël Stevens, wrote the book Comment tout peut s'effondrer (literally, "How everything can collapse"). Another, decidedly transdisciplinary approach which has been coined in late 2010s by German researcher Karim Fathi is the concept of "multiresilience" taking into account the fact that crises in the 21st century are interconnected, multi-dimensional and occurring on multiple system levels. Challenges such as the COVID-19 pandemic (individuals, organisations, societies alike) occur simultaneously, often even in interconnected and clustered forms. From a cross-disciplinary perspective, Karim Fathi outlines five systemic principles contributing to increased collective intelligence, responsiveness and creativity of societies in the face of multiple crises occurring simultaneously. Multiresilience is regarded as complementary to already established concepts for assessing and promoting societal resilience potentials. At the same time it criticises the fact that societal resilience has so far always been discussed from a mono-crisis persperctive. According to Karim Fathi, this onesided perspective" proves to be inadequate in terms of complexity, as societies in the 21st century have to deal with many global challenges - so-called „crisis-bundles“ - in the same time. Multiresilience aims to build up "basic robustness" in the sense of higher collective intelligence, which makes societies more capable of anticipating, reacting and solving problems in different crisis contexts.

Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife. Natural resources is a part of humanity's natural heritage or protected in nature reserves. Particular areas (such as the rainforest in Fatu-Hiva) often feature biodiversity and geodiversity in their ecosystems. Natural resources may be classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, air, as well as any living organism such as a fish, or it may be transformed by extractivist industries into an economically useful form that must be processed to obtain the resource such as metal ores, rare-earth elements, petroleum, timber and most forms of energy. Some resources are renewable resource, which means that they can be used at a certain rate and natural processes will restore them, whereas many extractive industries rely heavily on non-renewable resources that can only be extracted once. Natural-resource allocations can be at the center of many economic and political confrontations both within and between countries. This is particularly true during periods of increasing scarcity and shortages (depletion and overconsumption of resources). Resource extraction is also a major source of human rights violations and environmental damage. The Sustainable Development Goals and other international development agendas frequently focus on creating more sustainable resource extraction, with some scholars and researchers focused on creating economic models, such as circular economy, that rely less on resource extraction, and more on reuse, recycling and renewable resources that can be sustainably managed.

A street is a public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as tarmac, concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with rails, or otherwise prepared to accommodate non-pedestrian traffic. Originally, the word street simply meant a paved road (Latin: via strata). The word street is still sometimes used informally as a synonym for road, for example in connection with the ancient Watling Street, but city residents and urban planners draw a crucial modern distinction: a road's main function is transportation, while streets facilitate public interaction. Examples of streets include pedestrian streets, alleys, and city-centre streets too crowded for road vehicles to pass. Conversely, highways and motorways are types of roads, but few would refer to them as streets. (en)  +

Homelessness or houselessness – also known as a state of being unhoused or unsheltered – is the condition of lacking stable, safe, and adequate housing. People can be categorized as homeless if they are: * living on the streets, also known as rough sleeping (primary homelessness); * moving between temporary shelters, including houses of friends, family, and emergency accommodation (secondary homelessness); and * living in private boarding houses without a private bathroom or security of tenure (tertiary homelessness). * have no permanent house or place to live safely * Internally Displaced Persons, persons compelled to leave their places of domicile, who remain as refugees within their country's borders. The rights of people experiencing homelessness also varies from country to country. United States government homeless enumeration studies also include people who sleep in a public or private place, which is not designed for use as a regular sleeping accommodation for human beings. Homelessness and poverty are interrelated. There is no methodological consensus on counting homeless people and identifying their needs; therefore, in most cities, only estimated homeless populations are known. In 2005, an estimated 100 million people worldwide were homeless, and as many as one billion people (one in 6.5 at the time) live as squatters, refugees, or in temporary shelter, all lacking adequate housing. Scarce and expensive housing is the main cause of rising homelessness in the United States. (en)  +
La santé est « un état de complet bien-être physique, mental et social, et ne consiste pas seulement en une absence de maladie ou d'infirmité ». Dans cette définition par l'Organisation mondiale de la santé, OMS, depuis 1946, la santé représente « l’un des droits fondamentaux de tout être humain, quelles que soient sa race, sa religion, ses opinions politiques, sa condition économique ou sociale ». Elle implique la satisfaction de tous les besoins fondamentaux de la personne, qu'ils soient affectifs, sanitaires, nutritionnels, sociaux ou culturels.. Mais cette définition confond les notions de santé et de bien-être. Par ailleurs, « la santé résulte d’une interaction constante entre l’individu et son milieu » et représente donc « cette « capacité physique, psychique et sociale des personnes d’agir dans leur milieu et d’accomplir les rôles qu’elles entendent assumer d’une manière acceptable pour elles-mêmes et pour les groupes dont elles font partie ». René Dubos présente en 1973 la santé comme « la situation dans laquelle l'organisme réagit par une adaptation tout en préservant son intégrité individuelle. C'est l'état physique et mental relativement exempt de gênes et de souffrances qui permet à l'individu de fonctionner aussi longtemps que possible dans le milieu où le hasard ou le choix l'ont placé. » Pour René Leriche en 1936, « la santé c'est la vie dans le silence des organes. » (fr)  +, Health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity". A variety of definitions have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders. (en)  +, La salud (del latín salus, -utis) es un estado de bienestar o de equilibrio que puede ser visto a nivel subjetivo (un ser humano asume como aceptable el estado general en el que se encuentra) o a nivel objetivo (se constata la ausencia de enfermedades o de factores dañinos en el sujeto en cuestión). El término salud se contrapone al de enfermedad, y es objeto de especial atención por parte de la medicina y de las ciencias de la salud. (es)  +
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of health takes into account physical, psychological, and social well-being. Public health is an interdisciplinary field. For example, epidemiology, biostatistics, social sciences and management of health services are all relevant. Other important sub-fields include environmental health, community health, behavioral health, health economics, public policy, mental health, health education, health politics, occupational safety, disability, oral health, gender issues in health, and sexual and reproductive health. Public health, together with primary care, secondary care, and tertiary care, is part of a country's overall health care system. Public health is implemented through the surveillance of cases and health indicators, and through the promotion of healthy behaviors. Common public health initiatives include promotion of hand-washing and breastfeeding, delivery of vaccinations, promoting ventilation and improved air quality both indoors and outdoors, suicide prevention, smoking cessation, obesity education, increasing healthcare accessibility and distribution of condoms to control the spread of sexually transmitted diseases. There is a significant disparity in access to health care and public health initiatives between developed countries and developing countries, as well as within developing countries. In developing countries, public health infrastructures are still forming. There may not be enough trained healthcare workers, monetary resources, or, in some cases, sufficient knowledge to provide even a basic level of medical care and disease prevention. A major public health concern in developing countries is poor maternal and child health, exacerbated by malnutrition and poverty coupled with governments' reluctance in implementing public health policies. From the beginnings of human civilization, communities promoted health and fought disease at the population level. In complex, pre-industrialized societies, interventions designed to reduce health risks could be the initiative of different stakeholders, such as army generals, the clergy or rulers. Great Britain became a leader in the development of public health initiatives, beginning in the 19th century, due to the fact that it was the first modern urban nation worldwide. The public health initiatives that began to emerge initially focused on sanitation (for example, the Liverpool and London sewerage systems), control of infectious diseases (including vaccination and quarantine) and an evolving infrastructure of various sciences, e.g. statistics, microbiology, epidemiology, sciences of engineering.

Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek manuscripts from the dying Byzantine Empire to Western Europe in the Renaissance. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived "natural philosophy", which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape; along with the changing of "natural philosophy" to "natural science". Modern science is typically divided into three major branches: natural sciences (e.g., biology, chemistry, and physics), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules. There is disagreement whether the formal sciences are science disciplines, because they do not rely on empirical evidence. Applied sciences are disciplines that use scientific knowledge for practical purposes, such as in engineering and medicine. New knowledge in science is advanced by research from scientists who are motivated by curiosity about the world and a desire to solve problems. Contemporary scientific research is highly collaborative and is usually done by teams in academic and research institutions, government agencies, and companies. The practical impact of their work has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the ethical and moral development of commercial products, armaments, health care, public infrastructure, and environmental protection.

Open science is the movement to make scientific research (including publications, data, physical samples, and software) and its dissemination accessible to all levels of society, amateur or professional. Open science is transparent and accessible knowledge that is shared and developed through collaborative networks. It encompasses practices such as publishing open research, campaigning for open access, encouraging scientists to practice open-notebook science (such as openly sharing data and code), broader dissemination and engagement in science and generally making it easier to publish, access and communicate scientific knowledge. Usage of the term varies substantially across disciplines, with a notable prevalence in the STEM disciplines. Open research is often used quasi-synonymously to address the gap that the denotion of "science" might have regarding an inclusion of the Arts, Humanities and Social Sciences. The primary focus connecting all disciplines is the widespread uptake of new technologies and tools, and the underlying ecology of the production, dissemination and reception of knowledge from a research-based point-of-view. As Tennant et al. (2020) note, the term open science "implicitly seems only to regard ‘scientific’ disciplines, whereas open scholarship can be considered to include research from the Arts and Humanities, as well as the different roles and practices that researchers perform as educators and communicators, and an underlying open philosophy of sharing knowledge beyond research communities." Open science can be seen as a continuation of, rather than a revolution in, practices begun in the 17th century with the advent of the academic journal, when the societal demand for access to scientific knowledge reached a point at which it became necessary for groups of scientists to share resources with each other. In modern times there is debate about the extent to which scientific information should be shared. The conflict that led to the Open Science movement is between the desire of scientists to have access to shared resources versus the desire of individual entities to profit when other entities partake of their resources. Additionally, the status of open access and resources that are available for its promotion are likely to differ from one field of academic inquiry to another. (en)  
La sécheresse ou sècheresse \sɛʃ.ʁɛs\ définit l'état d'un environnement confronté à un manque d'eau significativement long et important pour qu'il ait des impacts sur la flore (naturelle ou cultivée), la faune (sauvage ou d'élevage) et les sociétés. Sécheresse ne doit pas être confondu avec aridité. Une région aride peut connaître des épisodes de sécheresse. Le déficit hydrique est une situation naturelle du point de vue de la variabilité climatique (par exemple, les périodes glaciaires/interglaciaires du Quaternaire, les cycles El Niño / La Niña, etc.) mais, selon certains climatologues certaines situations de déficit hydrique sont amplifiées (durée, extension spatiale, intensité) par l'émission humaine de gaz à effet de serre. Il fait suite à un déficit pluviométrique, sur de longues périodes durant lesquelles les précipitations sont anormalement faibles ou insuffisantes pour maintenir l'humidité du sol et l'hygrométrie normale de l'air. Il peut être aggravé ou expliqué par des pompages, une baisse du niveau de la nappe phréatique, l'érosion et la dégradation des sols (l'humus favorise la rétention de l'eau, la coupe à blanc de zones forestières dans la région de l'Amazonie, par exemple, entraîne rapidement la perte de cet humus essentiel à la rétention de l'eau et cause une désertification accélérée d'origine anthropique), une augmentation de l'évapotranspiration induite par des plantations consommatrices d'eau (peupliers, maïs). La sécheresse peut détruire les récoltes (partiellement ou totalement) et tuer les animaux d'élevage, et parfois sauvages. Elle devient alors un facteur de famine régionale et d'exode, souvent accompagnée de troubles sociaux voire de conflits armés en particulier dans les régions de peu de ressources économiques. La sécheresse n'est donc pas qu'un phénomène physique ou climatique objectif. C'est aussi une notion relative qui reflète l'écart entre la disponibilité de l'eau et la demande en eau de l'homme (savoir les applications agricoles – agriculture, du bétail – industrielles, domestiques de l'eau – hygiène, alimentation, lavage – dont certains usages d'une nécessité secondaire – piscine, arrosage des gazons, lavage de voiture – , etc.). Ceci rend toute définition de la sécheresse relative au contexte géopolitique et sociologique ; l'état « normal » de disponibilité de l'eau change selon les zones biogéographiques et les besoins réels ou ressentis des individus et des sociétés. La sécheresse s'initie par une sécheresse météorologique se produisent généralement lorsqu'un anticyclone s'installe durablement au-dessus d'une région à cause d'une situation de blocage. Les hautes pressions persistantes empêchent donc toute intrusion d'une perturbation atmosphérique et peuvent alors mener la région surplombée par celles-ci à une longue période de beau temps et donc avec un peu voire sans précipitations. (fr)  , A drought is defined as drier than normal conditions. This means that a drought is "a moisture deficit relative to the average water availability at a given location and season". A drought can last for days, months or years. Drought often exerts substantial impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy. Annual dry seasons in the tropics significantly increase the chances of a drought developing and subsequent wildfires. Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour. Drought is a recurring feature of the climate in most parts of the world, becoming more extreme and less predictable due to climate change, which dendrochronological studies date back to 1900. There are three kinds of drought effects, environmental, economic and social. Environmental effects include the drying of wetlands, more and larger wildfires, loss of biodiversity. Economic consequences include disruption of water supplies for municipal economies; lower agricultural, forest, game, and fishing outputs; higher food-production costs; and problems with water supply for the energy sector. Social and health costs include the negative effect on the health of people directly exposed to this phenomenon (excessive heat waves), high food costs, stress caused by failed harvests, water scarcity, etc. Prolonged droughts have caused mass migrations and humanitarian crisis. Many plant species, such as those in the family Cactaceae (or cacti), have drought tolerance adaptations like reduced leaf area and waxy cuticles to enhance their ability to tolerate drought. Some others survive dry periods as buried seeds. Semi-permanent drought produces arid biomes such as deserts and grasslands. Most arid ecosystems have inherently low productivity. The most prolonged drought ever in the world in recorded history continues in the Atacama Desert in Chile (400 years). Throughout history, humans have usually viewed droughts as "disasters" due to the impact on food availability and the rest of society. Humans have often tried to explain droughts as either a natural disaster, caused by humans, or the result of supernatural forces. (en)  
Security is protection from, or resilience against, potential harm (or other unwanted coercive change) caused by others, by restraining the freedom of others to act. Beneficiaries (technically referents) of security may be of persons and social groups, objects and institutions, ecosystems or any other entity or phenomenon vulnerable to unwanted change. Security mostly refers to protection from hostile forces, but it has a wide range of other senses: for example, as the absence of harm (e.g. freedom from want); as the presence of an essential good (e.g. food security); as resilience against potential damage or harm (e.g. secure foundations); as secrecy (e.g. a secure telephone line); as containment (e.g. a secure room or cell); and as a state of mind (e.g. emotional security). The term is also used to refer to acts and systems whose purpose may be to provide security (e.g.: security companies, security forces, security guard, cyber security systems, security cameras, remote guarding). Security is not only physical but it can also be virtual. (en)  +
Food security speaks to the availability of food in a country (or geography) and the ability of individuals within that country (geography) to access, afford, and source adequate foodstuffs. According to the United Nations' Committee on World Food Security, food security is defined as meaning that all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their food preferences and dietary needs for an active and healthy life. The availability of food irrespective of class, gender or region is another element of food security. There is evidence of food security being a concern many thousands of years ago, with central authorities in ancient China and ancient Egypt being known to release food from storage in times of famine. At the 1974 World Food Conference, the term "food security" was defined with an emphasis on supply; food security is defined as the "availability at all times of adequate, nourishing, diverse, balanced and moderate world food supplies of basic foodstuffs to sustain a steady expansion of food consumption and to offset fluctuations in production and prices". Later definitions added demand and access issues to the definition. The first World Food Summit, held in 1996, stated that food security "exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life." Similarly, household food security is considered to exist when all members, at all times, have access to enough food for an active, healthy life. Individuals who are food secure do not live in hunger or fear of starvation. Food insecurity, on the other hand, is defined by the United States Department of Agriculture (USDA) as a situation of "limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire acceptable foods in socially acceptable ways". Food security incorporates a measure of resilience to future disruption or unavailability of critical food supply due to various risk factors including droughts, shipping disruptions, fuel shortages, economic instability, and wars. The Food and Agriculture Organization of the United Nations, or FAO, identified the four pillars of food security as availability, access, utilization, and stability. The United Nations (UN) recognized the Right to Food in the Declaration of Human Rights in 1948, and has since said that it is vital for the enjoyment of all other rights. The 1996 World Summit on Food Security declared that "food should not be used as an instrument for political and economic pressure". Multiple different international agreements and mechanisms have been developed to address food security. The main global policy to reduce hunger and poverty is in the Sustainable Development Goals. In particular Goal 2: Zero Hunger sets globally agreed on targets to end hunger, achieve food security and improved nutrition, and promote sustainable agriculture by 2030. (en)  
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general meaning that antedates the above – anything that can be sown, e.g. "seed" potatoes, "seeds" of corn or sunflower "seeds". In the case of sunflower and corn "seeds", what is sown is the seed enclosed in a shell or husk, whereas the potato is a tuber. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate it. Many structures commonly referred to as "seeds" are actually dry fruits. Sunflower seeds are sometimes sold commercially while still enclosed within the hard wall of the fruit, which must be split open to reach the seed. Different groups of plants have other modifications, the so-called stone fruits (such as the peach) have a hardened fruit layer (the endocarp) fused to and surrounding the actual seed. Nuts are the one-seeded, hard-shelled fruit of some plants with an indehiscent seed, such as an acorn or hazelnut. (en)  +
A public service is any service intended to address specific needs pertaining to the aggregate members of a community. Public services are available to people within a government jurisdiction as provided directly through public sector agencies or via public financing to private businesses or voluntary organizations (or even as provided by family households, though terminology may differ depending on context). Other public services are undertaken on behalf of a government's residents or in the interest of its citizens. The term is associated with a social consensus (usually expressed through democratic elections) that certain services should be available to all, regardless of income, physical ability or mental acuity. Examples of such services include the fire brigade, police, air force, and paramedics (see also public service broadcasting). Even where public services are neither publicly provided nor publicly financed, they are usually subject to regulation going beyond that applying to most economic sectors for social and political reasons. Public policy, when made in the public's interest and with its motivations, is a type of public service. (en)  +
Solidarity is an awareness of shared interests, objectives, standards, and sympathies creating a psychological sense of unity of groups or classes. It is based on class collaboration. It refers to the ties in a society that bind people together as one. The term is generally employed in sociology and the other social sciences as well as in philosophy and bioethics. It is also a significant concept in Catholic social teaching; therefore it is a core concept in Christian democratic political ideology. What forms the basis of solidarity and how it is implemented vary between societies. In global south societies it may be mainly based on kinship and shared values while global north societies accumulate various theories as to what contributes to a sense of solidarity, or rather, social cohesion. Unlike collectivism, solidarism does not reject individuals and sees individuals as the basis of society. Solidarity is also one of six principles of the Charter of Fundamental Rights of the European Union and December 20 of each year is International Human Solidarity Day recognized as an international observance. Concepts of solidarity are mentioned in the Universal Declaration on Bioethics and Human Rights, but not defined clearly. As biotechnology and biomedical enhancement research and production increase, the need for distinct definition of solidarity within healthcare system frameworks is important. However, solidarity is not mentioned in the European Convention on Human Rights nor in the United Nations' Universal Declaration of Human Rights and has hence lesser legal meaning when compared to basic rights.

Sovereignty is the defining authority within individual consciousness, social construct, or territory. Sovereignty entails hierarchy within the state, as well as external autonomy for states. In any state, sovereignty is assigned to the person, body, or institution that has the ultimate authority over other people in order to establish a law or change an existing law. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. In international law, sovereignty is the exercise of power by a state. De jure sovereignty refers to the legal right to do so; de facto sovereignty refers to the factual ability to do so. This can become an issue of special concern upon the failure of the usual expectation that de jure and de facto sovereignty exist at the place and time of concern, and reside within the same organization.

Food sovereignty is a food system in which the people who produce, distribute, and consume food also control the mechanisms and policies of food production and distribution. This stands in contrast to the present corporate food regime, in which corporations and market institutions control the global food system. Food sovereignty emphasizes local food economies, sustainable food availability, and center culturally appropriate foods and practices. Changing climates and disrupted foodways disproportionately impact indigenous populations and their access to traditional food sources while contributing to higher rates of certain diseases; for this reason, food sovereignty centers indigenous peoples. These needs have been addressed in recent years by several international organizations, including the United Nations, with several countries adopting food sovereignty policies into law. Critics of food sovereignty activism believe that the system is founded on inaccurate baseline assumptions; disregards the origins of the targeted problems; and is plagued by a lack of consensus for proposed solutions. (en)  +, La souveraineté alimentaire est un concept développé et présenté pour la première fois par Via Campesina lors du Sommet de l'alimentation organisé par la FAO à Rome en 1996. Il a depuis été repris et précisé par divers courants altermondialistes lors de différents Forums Sociaux Mondiaux. La souveraineté alimentaire est présentée comme un droit international qui laisse la possibilité aux populations, aux États ou aux groupes d'États de mettre en place les politiques agricoles les mieux adaptées à leurs populations sans qu'elles puissent avoir un effet négatif sur les populations d'autres pays. Elle se construit à l'origine dans l'objectif de permettre le respect des droits des paysans. La souveraineté alimentaire est donc une rupture par rapport à l'organisation actuelle des marchés agricoles mise en œuvre par l'OMC. Complémentaire du concept de sécurité alimentaire qui concerne la quantité d'aliments disponibles, l'accès des populations à ceux-ci, l'utilisation biologique des aliments et le problème de la prévention et gestion des crises, la souveraineté alimentaire accorde en plus une importance aux conditions sociales et environnementales de production des aliments. Elle prône un accès plus équitable à la terre pour les paysans pauvres, au moyen si nécessaire d'une réforme agraire et de mécanismes de sécurisation des droits d'usage du foncier. Au niveau local, les défenseurs de la souveraineté alimentaire favorisent le maintien d'une agriculture de proximité destinée en priorité à alimenter les marchés régionaux et nationaux. Les cultures vivrières et l'agriculture familiale de petite échelle sont présentées par les défenseurs de la souveraineté alimentaire comme étant d'une grande efficacité économique[réf. nécessaire], sociale[réf. nécessaire] et environnementale[réf. nécessaire], comparée à l'agriculture industrielle et les plantations de grande échelle où travaillent de nombreux salariés. La place et le rôle des femmes sont privilégiés. La souveraineté alimentaire privilégie des techniques agricoles qui favorisent l'autonomie des paysans. Elle est donc favorable à l'agriculture biologique et à l'agriculture paysanne. Elle refuse l'utilisation des plantes transgéniques en agriculture. (fr)  
Sport pertains to any form of competitive physical activity or game that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a match) is between two sides, each attempting to exceed the other. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs. Sport is generally recognised as system of activities based in physical athleticism or physical dexterity, with major competitions such as the Olympic Games admitting only sports meeting this definition. Other organisations, such as the Council of Europe, preclude activities without a physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports. The International Olympic Committee (through ARISF) recognises both chess and bridge as bona fide sports, and SportAccord, the international sports federation association, recognises five non-physical sports: bridge, chess, draughts (checkers), Go and xiangqi, and limits the number of mind games which can be admitted as sports. Sport is usually governed by a set of rules or customs, which serve to ensure fair competition, and allow consistent adjudication of the winner. Winning can be determined by physical events such as scoring goals or crossing a line first. It can also be determined by judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression. Records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news. Sport is also a major source of entertainment for non-participants, with spectator sport drawing large crowds to sport venues, and reaching wider audiences through broadcasting. Sport betting is in some cases severely regulated, and in some cases is central to the sport. According to A.T. Kearney, a consultancy, the global sporting industry is worth up to $620 billion as of 2013. The world's most accessible and practised sport is running, while association football is the most popular spectator sport. (en)
