Common Good (economics)
Common goods (also called common-pool resources) are defined in economics as goods that are rivalrous and non-excludable. Thus, they constitute one of the four main types based on the criteria: * whether the consumption of a good by one person precludes its consumption by another person ( rivalrousness) * whether it is possible to prevent people (consumers) who have not paid for it from having access to it (excludability) As common goods are accessible by everybody, they are at risk of being subject to overexploitation which leads to diminished availability if people act to serve their own self-interests. Characteristics of common goods Common-pool resources are sufficiently large that it is difficult, but not impossible, to define recognized users and exclude other users altogether. Based on the criteria, common goods are: * rivalrous: When one person consumes a good, another person is unable to subsequently consume that good and the overall stock of the good decreases. For ...

Man Fishing From The Banks Of A Lake In Burkina Faso, 2009
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional gender roles have often defined ...

The Social Contract
''The Social Contract'', originally published as ''On the Social Contract; or, Principles of Political Right'' (french: Du contrat social; ou, Principes du droit politique), is a 1762 French-language book by the Genevan philosopher Jean-Jacques Rousseau. The book theorizes about the best way to establish a political community in the face of the problems of commercial society, which Rousseau had already identified in his ''Discourse on Inequality'' (1755). ''The Social Contract'' helped inspire political reforms or revolutions in Europe, especially in France. ''The Social Contract'' argued against the idea that monarchs were divinely empowered to legislate. Rousseau asserts that only the people, who are sovereign, have that all-powerful right. Overview The epigraph of the work is "foederis aequas / dicamus leges" Let us set equal terms for the truce. (Virgil, ''Aeneid'' XI.321–22). The stated aim of ''The Social Contract'' is to determine whether there can be a legitimate p ...

Property Rights
The right to property, or the right to own property (cf. ownership) is often classified as a human right for natural persons regarding their possessions. A general recognition of a right to private property is found more rarely and is typically heavily constrained insofar as property is owned by legal persons (i.e. corporations) and where it is used for production rather than consumption. A right to property is recognised in Article 17 of the Universal Declaration of Human Rights, but it is not recognised in the International Covenant on Civil and Political Rights or the International Covenant on Economic, Social and Cultural Rights. The European Convention on Human Rights, in Protocol 1, article 1, acknowledges a right for natural and legal persons to "peaceful enjoyment of his possessions", subject to the "general interest or to secure the payment of taxes." Definition The right to property is one of the most controversial human rights, both in terms of its existence and inte ...

Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ...

Shepherd
A shepherd or sheepherder is a person who tends, herds, feeds, or guards flocks of sheep. ''Shepherd'' derives from Old English ''sceaphierde (''sceap'' 'sheep' + ''hierde'' 'herder'). ''Shepherding is one of the world's oldest occupations, it exists in all parts of the globe, and it is an important part of Pastoralism, pastoralist animal husbandry. Because of the ubiquity of the profession, many religions and cultures have symbolic or metaphorical references to the shepherd profession. For example, Jesus called himself the Good Shepherd, and ancient Greek mythologies highlighted shepherds such as Endymion (mythology), Endymion and Daphnis. This symbolism and shepherds as characters are at the center of pastoral literature and art. Origins Shepherding is among the oldest occupations, beginning some 5,000 years ago in Asia Minor. Sheep were kept for their milk, sheep meat, meat and especially their wool. Over the next thousand years, sheep and shepherding spread throughout ...

Tragedy Of The Commons
Tragedy (from the grc-gre, τραγῳδία, ''tragōidia'', ''tragōidia'') is a genre of drama based on human suffering and, mainly, the terrible or sorrowful events that befall a main character. Traditionally, the intention of tragedy is to invoke an accompanying catharsis, or a "pain hatawakens pleasure", for the audience. While many cultures have developed forms that provoke this paradoxical response, the term ''tragedy'' often refers to a specific tradition of drama that has played a unique and important role historically in the self-definition of Western civilization. That tradition has been multiple and discontinuous, yet the term has often been used to invoke a powerful effect of cultural identity and historical continuity—"the Greeks and the Elizabethans, in one cultural form; Hellenes and Christians, in a common activity," as Raymond Williams puts it. From its origins in the theatre of ancient Greece 2500 years ago, from which there survives only a fraction ...

Common-pool Resource
In economics, a common-pool resource (CPR) is a type of good consisting of a natural or human-made resource system (e.g. an irrigation system or fishing grounds), whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. Unlike pure public goods, common pool resources face problems of congestion or overuse, because they are subtractable. A common-pool resource typically consists of a core resource (e.g. water or fish), which defines the ''stock variable'', while providing a limited quantity of extractable fringe units, which defines the ''flow variable''. While the core resource is to be protected or nurtured in order to allow for its continuous exploitation, the fringe units can be harvested or consumed. Examples of a Common-Pool Resource Common-pool goods are typically regulated and nurtured in order to prevent demand from overwhelming supply and allow for their continued exploitation. Examples of ...

Renewable Resource
A renewable resource, also known as a flow resource, is a natural resource which will replenish to replace the portion resource depletion, depleted by usage and consumption, either through natural reproduction or other recurring processes in a finite amount of time in a human time scale. When the recovery rate of resources is unlikely to ever exceed a human time scale, these are called perpetual resources. Renewable resources are a part of Earth's natural environment and the largest components of its Ecosphere (ecology), ecosphere. A positive life-cycle assessment is a key indicator of a resource's sustainability. Definitions of renewable resources may also include agricultural production, as in sustainable agriculture, agricultural products and to an extent water resources.What are “Renewa ...

Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include: growth overfishing, recruitment overfishing, ecosystem overfishing. The ability of a fishery to recover from overfishing depends on whether its overall carrying capacity and the variety of ecological conditions are suitable for t ...

Sustainability
Specific definitions of sustainability are difficult to agree on and have varied in the literature and over time. The concept of sustainability can be used to guide decisions at the global, national, and individual levels (e.g. sustainable living). Sustainability is commonly described as having three dimensions (also called pillars): environmental, economic, and social. Many publications state that the environmental dimension (also called "planetary integrity" or "ecological integrity") is the most important, and, in everyday usage, "sustainability" is often focused on countering major environmental problems, such as climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. Humanity is now exceeding several "planetary boundaries". A closely related concept is that of sustainable development, and the terms are often used synonymously. However, UNESCO distinguishes the two thus: "''Sustainability'' is often thought of as a lon ...

Externality
In economics, an externality or external cost is an indirect cost or benefit to an uninvolved third party that arises as an effect of another party's (or parties') activity. Externalities can be considered as unpriced goods involved in either consumer or producer market transactions. Air pollution from motor vehicles is one example. The cost of air pollution to society is not paid by either the producers or users of motorized transport to the rest of society. Water pollution from mills and factories is another example. All consumers are all made worse off by pollution but are not compensated by the market for this damage. A positive externality is when an individual's consumption in a market increases the well-being of others, but the individual does not charge the third party for the benefit. The third party is essentially getting a free product. An example of this might be the apartment above a bakery receiving the benefit of enjoyment from smelling fresh pastries every mornin ...
