The World Portal
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of parts.
In scientific cosmology, the world or universe is commonly defined as "[t]he totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, as identical to God or as the two being interdependent. In religions, there is a tendency to downgrade the material or sensory world in favor of a spiritual world to be sought through religious practice. A comprehensive representation of the world and our place in it, as is found in religions, is known as a worldview. Cosmogony is the field that studies the origin or creation of the world while eschatology refers to the science or doctrine of the last things or of the end of the world.
In various contexts, the term "world" takes a more restricted meaning associated, for example, with the Earth and all life on it, with humanity as a whole or with an international or intercontinental scope. In this sense, world history refers to the history of humanity as a whole and world politics is the discipline of political science studying issues that transcend nations and continents. Other examples include terms such as "world religion", "world language", "world government", "world war", "world population", "world economy", or "world championship". (Full article...)

The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention colloquially denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone.
The Geneva Conventions define the rights and protections afforded to non-combatants who fulfill the criteria of being protected persons. The treaties of 1949 were ratified, in their entirety or with reservations, by 196 countries. The Geneva Conventions concern only protected non-combatants in war. The use of wartime conventional weapons is addressed by the Hague Conventions of 1899 and 1907 and the 1980 Convention on Certain Conventional Weapons, while the biological and chemical warfare in international armed conflicts is addressed by the 1925 Geneva Protocol.

Culture (/ˈkʌltʃər/ KUL-chər) is a concept that encompasses the social behavior, institutions, and norms found in human societies, as well as the knowledge, beliefs, arts, laws, customs, capabilities, and habits of the individuals in these groups. Culture is often originated from or attributed to a specific region or location.
Humans acquire culture through the learning processes of enculturation and socialization, which is shown by the diversity of cultures across societies. (Full article...) -
Image 4World Englishes is a term for emerging localised or indigenised varieties of English, especially varieties that have developed in territories influenced by the United Kingdom or the United States. The study of World Englishes consists of identifying varieties of English used in diverse sociolinguistic contexts globally and analyzing how sociolinguistic histories, multicultural backgrounds and contexts of function influence the use of English in different regions of the world.
The issue of World Englishes was first raised in 1978 to examine concepts of regional Englishes globally. Pragmatic factors such as appropriateness, comprehensibility and interpretability justified the use of English as an international and intra-national language. In 1988, at a Teachers of English to Speakers of Other Languages (TESOL) conference in Honolulu, Hawaii, the International Committee of the Study of World Englishes (ICWE) was formed. In 1992, the ICWE formally launched the International Association for World Englishes (IAWE) at a conference of "World Englishes Today", at the University of Illinois, USA. There are two academic journals devoted to the study of this topic, titled English World-Wide (since 1980) and World Englishes (since 1982). There are a number of published handbooks and textbooks on the subject. (Full article...) -

The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity.
The concept of the natural environment can be distinguished as components:- Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, the atmosphere, and natural phenomena that occur within their boundaries and their nature.
- Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from civilized human actions.
In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, and the works of mound-building termites, are thought of as natural.

The International Development Association (IDA) (French: Association internationale de développement) is a development finance institution which offers concessional loans and grants to the world's poorest developing countries. The IDA is a member of the World Bank Group and is headquartered in Washington, D.C. in the United States. It was established in 1960 to complement the existing International Bank for Reconstruction and Development by lending to developing countries which suffer from the lowest gross national income, from troubled creditworthiness, or from the lowest per capita income. Together, the International Development Association and International Bank for Reconstruction and Development are collectively generally known as the World Bank, as they follow the same executive leadership and operate with the same staff.
The association shares the World Bank's mission of reducing poverty and aims to provide affordable development financing to countries whose credit risk is so prohibitive that they cannot afford to borrow commercially or from the Bank's other programs. The IDA's stated aim is to assist the poorest nations in growing more quickly, equitably, and sustainably to reduce poverty. The IDA is the single largest provider of funds to economic and human development projects in the world's poorest nations. From 2000 to 2010, it financed projects which recruited and trained 3 million teachers, immunized 310 million children, funded $792 million in loans to 120,000 small and medium enterprises, built or restored 118,000 kilometers of paved roads, built or restored 1,600 bridges, and expanded access to improved water to 113 million people and improved sanitation facilities to 5.8 million people. The IDA has issued a total US$238 billion in loans and grants since its launch in 1960. Thirty-six of the association's borrowing countries have graduated from their eligibility for its concessional lending. However, nine of these countries have relapsed and have not re-graduated.

Cyprus (/ˈsaɪprəs/ ⓘ), officially the Republic of Cyprus, is an island country in the eastern Mediterranean Sea, north of the Sinai Peninsula, south of the Anatolian Peninsula, and west of the Levant. It is geographically a part of West Asia, but its cultural ties and geopolitics are overwhelmingly Southeast European. Cyprus is the third-largest and third-most populous island in the Mediterranean. It is east of Greece, north of Egypt, south of Turkey, and west of Lebanon and Syria. Its capital and largest city is Nicosia. The northeast portion of the island is de facto governed by the self-declared Turkish Republic of Northern Cyprus.
Cyprus is home to some of the oldest water wells in the world. Cyprus was settled by Mycenaean Greeks in two waves in the 2nd millennium BC. As a strategic location in the Eastern Mediterranean, it was subsequently occupied by several major powers, including the empires of the Assyrians, Egyptians and Persians, from whom the island was seized in 333 BC by Alexander the Great. Subsequent rule by Ptolemaic Egypt, the Classical and Eastern Roman Empire, Arab caliphates for a short period, the French Lusignan dynasty and the Venetians was followed by over three centuries of Ottoman rule between 1571 and 1878 (de jure until 1914).

Many parts of Scotland are protected in accordance with a number of national and international designations because of their environmental, historical or cultural value. Protected areas can be divided according to the type of resource which each seeks to protect. NatureScot has various roles in the delivery of many environmental designations in Scotland, i.e. those aimed at protecting flora and fauna, scenic qualities and geological features. Historic Environment Scotland is responsible for designations that protect sites of historic and cultural importance. Some international designations, such as World Heritage Sites, can cover both categories of site.
The various designations overlap considerably with many protected areas being covered by multiple designations with different boundaries. (Full article...) -
