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...)

In world history, post-classical history refers to the period from about 500 CE to 1500 CE, roughly corresponding to the European Middle Ages. The period is characterized by the expansion of civilizations geographically and the development of trade networks between civilizations. This period is also called the medieval era, post-antiquity era, post-ancient era, pre-modernity era, or pre-modern era.
In Asia, the spread of Islam created a series of caliphates and inaugurated the Islamic Golden Age, leading to advances in science in the medieval Islamic world and trade among the Asian, African, and European continents. East Asia experienced the full establishment of the power of Imperial China, which established several prosperous dynasties influencing Japan, Korea, and Vietnam. Religions such as Buddhism and neo-Confucianism spread in the region. Gunpowder was developed in China during the post-classical era. The Mongol Empire connected Europe and Asia, creating safe trade and stability between the two regions. In total, the population of the world doubled in the time period, from approximately 210 million in 500 CE to 461 million in 1500 CE. The population generally grew steadily throughout the period but endured some incidental declines due to events including the Plague of Justinian, the Mongol invasions, and the Black Death.

A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions.
While some nations are widely considered to be great powers, there is considerable debate on the exact criteria of great power status. Historically, the status of great powers has been formally recognized in organizations such as the Congress of Vienna of 1814–1815 or the United Nations Security Council, of which permanent members are: China, France, Russia, the United Kingdom, and the United States. The United Nations Security Council, NATO Quint, the G7, the BRICs and the Contact Group have all been described as great power concerts. (Full article...) -

The United Nations (UN) is a diplomatic and political international organization whose stated purposes are to maintain international peace and security, develop friendly relations among nations, achieve international cooperation, and serve as a centre for harmonizing the actions of nations. It is the world's largest international organization. The UN is headquartered in New York City (in the United States, but with certain extraterritorial privileges), and the UN has other offices in Geneva, Nairobi, Vienna, and The Hague, where the International Court of Justice is headquartered at the Peace Palace.
The UN was established after World War II with the aim of preventing future world wars, and succeeded the League of Nations, which was characterized as ineffective. On 25 April 1945, 50 nations met in San Francisco, California for a conference and started drafting the UN Charter, which was adopted on 25 June 1945. The charter took effect on 24 October 1945, when the UN began operations. The UN's objectives, as defined by its charter, include maintaining international peace and security, protecting human rights, delivering humanitarian aid, promoting sustainable development, and upholding international law. At its founding, the UN had 51 member states; , it has 193 – almost all of the world's sovereign states. (Full article...) -

The United Nations Climate Change Conferences are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC). They serve as the formal meeting of the UNFCCC parties – the Conference of the Parties (COP) – to assess progress in dealing with climate change, and beginning in the mid-1990s, to negotiate the Kyoto Protocol to establish legally binding obligations for developed countries to reduce their greenhouse gas emissions. Starting in 2005 the conferences have also served as the "Conference of the Parties Serving as the Meeting of Parties to the Kyoto Protocol" (CMP); also parties to the convention that are not parties to the protocol can participate in protocol-related meetings as observers. From 2011 to 2015 the meetings were used to negotiate the Paris Agreement as part of the Durban platform, which created a general path towards climate action. Any final text of a COP must be agreed by consensus.
The first UN Climate Change Conference was held in 1995 in Berlin. (Full article...) -

Image 6Global village describes the phenomenon of the entire world becoming more interconnected as the result of the propagation of media technologies throughout the world. The term was coined by Canadian media theorist Marshall McLuhan in his books The Gutenberg Galaxy: The Making of Typographic Man (1962) and Understanding Media (1964). Literary scholar Sue-Im Lee describes how the term global village has come to designate “the dominant term for expressing a global coexistence altered by transnational commerce, migration, and culture” (as cited in Poll, 2012). Economic journalist Thomas Friedman's definition of the global village as a world “tied together into a single globalized marketplace and village” is another contemporary understanding of the term (as cited in Poll, 2012).

Istanbul, is the largest city in Turkey, straddling the Bosporus Strait, the boundary between Europe and Asia. It is considered the country's economic, cultural and historic capital. The city has a population of over 15 million residents, comprising 19% of the population of Turkey, and is the most populous city in Europe and the world's fifteenth-largest city.
The city was founded as Byzantium in the 7th century BCE by Greek settlers from Megara. In 330 CE, the Roman emperor Constantine the Great made it his imperial capital, renaming it first as New Rome (Ancient Greek: Νέα Ῥώμη Nea Rhomē; Latin: Nova Roma) and then finally as Constantinople (Constantinopolis) after himself. In 1930, the city's name was officially changed to Istanbul, the Turkish rendering of εἰς τὴν Πόλιν eis tḕn Pólin 'to the City', the appellation Greek speakers used since the 11th century to colloquially refer to the city.

Morocco, officially the Kingdom of Morocco, is a country in the Maghreb region of North Africa. It overlooks the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria to the east, and the disputed territory of Western Sahara to the south. Morocco also claims the Spanish exclaves of Ceuta, Melilla and Peñón de Vélez de la Gomera, and several small Spanish-controlled islands off its coast. It has a population of roughly 37 million, the official and predominant religion is Islam, and the official languages are Arabic and Berber; French and the Moroccan dialect of Arabic are also widely spoken. Moroccan identity and culture is a mix of Arab, Berber, African and European cultures. Its capital is Rabat, while its largest city is Casablanca.
The region constituting Morocco has been inhabited since the Paleolithic era over 300,000 years ago. The Idrisid dynasty was established by Idris I in 788 and was subsequently ruled by a series of other independent dynasties, reaching its zenith as a regional power in the 11th and 12th centuries, under the Almoravid and Almohad dynasties, when it controlled most of the Iberian Peninsula and the Maghreb. Centuries of Arab migration to the Maghreb since the 7th century shifted the demographic scope of the region. In the 15th and 16th centuries, Morocco faced external threats to its sovereignty, with Portugal seizing some territory and the Ottoman Empire encroaching from the east. The Marinid and Saadi dynasties otherwise resisted foreign domination, and Morocco was the only North African nation to escape Ottoman dominion. The 'Alawi dynasty, which rules the country to this day, seized power in 1631, and over the next two centuries expanded diplomatic and commercial relations with the Western world. Morocco's strategic location near the mouth of the Mediterranean drew renewed European interest; in 1912, France and Spain divided the country into respective protectorates, reserving an international zone in Tangier. Following intermittent riots and revolts against colonial rule, in 1956, Morocco regained its independence and reunified. (Full article...)Related portals

Image 2The protected areas of Nepal cover mainly forested land and are located at various altitudes in the Terai, in the foothills of the Himalayas and in the mountains, thus encompassing a multitude of landscapes and preserving a vast biodiversity in the Palearctic and Indomalayan realms.
Nepal covers 147,181 km2 (56,827 sq mi) in the central part of the Himalayas. Altitudes range from 67 m (220 ft) in the south-eastern Terai to 8,848 m (29,029 ft) at Mount Everest within a short horizontal span. This extreme altitudinal gradient has resulted in 11 bio-climatic zones ranging from lower tropical below 500 m (1,600 ft) to nival above 5,000 m (16,000 ft) in the High Himalayas, encompassing nine terrestrial ecoregions with 36 vegetation types.
Additionally, nine Ramsar sites were declared between 1988 and 2008. Two wildlife reserves were declared as national parks in 2017. (Full article...) -
