Muhammad and the Pillars of Islam

Muhammad is the prophet of Islam, born in the city of Mecca around 570 CE. The precepts of Islam are the obligations of a Muslim believer, contained in the holy book, the Quran. These are five core obligations:

1. To believe in one God, Allah, and His prophet Muhammad, and to profess one's faith (the Shahada).
2. To perform ritual prayer (Salat) at least five times a day, facing towards Mecca.
3. To give alms to the needy (Zakat).
4. To fast (Sawm) from dawn to dusk during the month of Ramadan.
5. To make the pilgrimage (Hajj) to Mecca, the holy city, at least once in a lifetime.

Islamic Economic Principles

The Islamic economy was primarily based on agriculture, which developed significantly in Arabia, and nomadic pastoralism, adapted... Continue reading "Foundations of Islam and Al-Andalus Civilization" »

Globalizing Cities and Population Shifts

The Transformation of Urban Economies

The late twentieth century witnessed a significant transformation in the urban economy, leading to the emergence of global cities. These cities, such as New York and Tokyo, are privileged sites due to their focus on international exchanges and production centers.

Urban Transformations

Global cities adapt to new global functions through the construction of new infrastructures, including transport and telecommunications networks. This often leads to strong price rises. Megacities are simple territorial agglomerations of human beings, characterized by social and regional differences.

• Privileged Areas: Inhabited by people with higher incomes.
• Marginalized Areas: Often found

Climate Change and Global Warming

13) Climate Change/Global Warming: Yes, it is the result of the increasing greenhouse effect, caused by rising emissions of greenhouse gases. These, in turn, result from the combustion of hydrocarbons. This leads to thawing that could raise sea levels, causing the disappearance of islands and coastal areas.

Energy Sources and Environmental Concerns

International Agreements

14) Kyoto Protocol: A commitment where signatory countries pledge to reduce or not increase their CO₂ emissions.

Energy Types

16) Traditional Sources: Wood, Coal, and later Oil and Natural Gas.

17) Nuclear Energy: Based on enriched uranium used as fuel. It generates hazardous radioactive waste that is difficult to treat. Radioactive waste can alter... Continue reading "Climate Impacts, Energy Choices, and Sustainable Futures" »

US Military Interventions in Middle East

The Gulf War marked a turning point in US foreign policy. In 1990, Saddam Hussein invaded Kuwait, a US ally. The US, backed by the UN Security Council, led an international coalition to liberate Kuwait. Iraq was ordered to pay compensation, destroy its chemical and nuclear weapons, and faced an oil embargo. The September 11, 2001 terrorist attacks, led by Al-Qaeda's Osama bin Laden, triggered a strong US military response. The US attacked Afghanistan's Taliban regime, which sheltered Al-Qaeda training camps. In March 2003, the US invaded Iraq, citing the existence of nuclear weapons and ties to terrorist groups, despite lacking UN support. Saddam Hussein was deposed and executed, but the US intervention... Continue reading "US Middle East Policy, Women's Rights, and Globalization" »

Geographic Location: Understanding "Where?"

Geography is primarily identified as the science of where?, followed by how? and why?. To find a location, we use geographic coordinates:

• Latitude: The arc of a meridian measured between the Equator and any point on a land area.
• Longitude: The parallel arc measured between the Prime Meridian (Greenwich or 0°) and any point on Earth's surface.

Other methods for location include the cardinal points and relative location.

Spatial Interaction: Principles and Factors

The geographical pattern of interaction potential is analogous to the classical physical model (the interaction between two bodies is a direct function of the product of their masses and inversely proportional to the distance between them). In... Continue reading "Understanding Geographic Location and Chile's Diverse Territory" »

Russia's Economy and Natural Resources

Russia is a leading global power in energy and possesses the largest reserves of iron (40% worldwide) and manganese (30% of the world's total). The dispersed location of its mines, oil, and natural gas deposits contributes to its decentralized industrial structure. Russian agriculture is constrained by climatic conditions. The Russian North is predominantly covered by forests, and the northern parts of Siberia are characterized by permafrost. Cereal crops are primarily cultivated in the central and southwestern regions with intensive agriculture.

Spain's Tertiary Sector in 2007: Regional Analysis

Choropleth thematic maps, where color intensity represents quantity, illustrate the state of Spain's tertiary sector in 2007. This analysis focuses on the sector's contribution to the working population and Gross Domestic Product (GDP) across different autonomous communities (regions).

National Overview and Regional Disparities

In Spain, the average contribution of the tertiary sector to national wealth was high at 66.8% in 2007, typical for a developed country. However, significant differences existed in the degree of economic tertiarization among regions.

Regional Groupings by Tertiary Sector Contribution

Based on the map legend, Spain's autonomous communities can be categorized into four groups... Continue reading "Spain's Tertiary Sector: 2007 Regional GDP Contributions" »
