Global Distribution of Economic Activities

Europe accounts for 8%, North America for 2%, Asia for 45%, and Africa for 58%.

Agricultural Activities

Agricultural activities occupy an important place because our food depends on this sector. These activities are developed in the agricultural landscape, characterized by:

1. Plot

• Shape, size, limit: Open field, closed field

2. Tillage Systems

• Harnessing the sun: Intensive, extensive
• Product range: Polyculture, monoculture
• Water management: Irrigated, dry

3. Settlement

• Sparse, centered

Types of Agriculture

• Subsistence: Itinerant cremation, extensive dry, irrigated rice
• Market: Opens in developed countries
• Objectives: Revenue + cost through field machining, production specialization, rapid commercialization of agricultural

Fishing in Spain

The Spanish Fishing Regions

The Spanish fishing space is organized into eight regions: Northwest, Cantabrian, Tramontana, Levant, South-Mediterranean, South Atlantic, Balearic, and Canary Islands. The most important region for its catch is the Northwest.

Fisheries Production Features

• The species caught: Fish constitute 3/4 of the catch, with the remaining being shellfish. White fish, such as hake and whiting, are particularly valuable.
• By tonnage: Sardines and anchovies are primarily caught for canning, followed by tuna and bonito.
• The main destination for fishing: Human consumption. Most of the catch is sold fresh, although salting, preserves, and freezing are increasing.
• Fishing landed: Experienced high growth until 1976, followed

Self-Regulation of Renewable Natural Resources

The regulatory mechanisms of renewable resources dictate the future of an ecosystem. Some individuals die, while others are born. Predation, a key component of food chains, helps maintain this balance. All living beings are interconnected and depend on each other. A food chain illustrates the nature of these food dependency relationships.

Understanding Food Chains

During photosynthesis, plants produce their own food and store reserve substances in parts like fruits, stems, roots, or seeds. Organisms that do not engage in photosynthesis require these supplies of food energy, either directly from plants or transferred through a series of organisms.

The relationship in a food chain is simple: one organism... Continue reading "Renewable Resources & Ecological Reserves: Conservation" »

Item 10: Agriculture

Agriculture is the cultivation of land to obtain food for human and animal consumption and raw materials for industry.

Agricultural Continuous Evolution: Very fast change of ownership patterns and land work.

Agricultural Development: In underdeveloped countries, agriculture represents a high percentage of production (80%) due to low-tech and traditional farming, resulting in low productivity. Only 5% of the population is dedicated to agriculture.

Physical Factors of Agriculture

• Weather: Each plant needs a certain humidity and temperature. Plants generally grow between -10ºC and +45ºC.
• Relief: Altitude and slope of terrain condition agricultural activity. Temperature decreases with altitude.
• Soil: Each plant requires specific

Mixed livestock animals combine food and life outdoors and in the barn.

Forestry Practices and Forest Management

Forestry farming is dedicated to harnessing the forest. The higher yields come from species in tropical hardwood forests and temperate regions. Forest types may be wooded or brush-covered. Forestry is the cultivation of forests or mountain areas in order to avoid degradation.

Shifting Cultivation in Tropical Africa

This agricultural practice is located in the equatorial zone and humid tropical climate of Africa. The agricultural landscape is made up of irregular parcels, located around towns, worked with quite primitive techniques and tools. The soil is cultivated continuously for two or three years until exhausted. When this happens,... Continue reading "Primary Economic Activities: Agriculture, Forestry, and Fishing" »

Geography of Population

Geography of Population studies the relationships established between people and space. It is the branch of Human Geography that studies the patterns or spatial structures of demographic phenomena in the human population and the processes of change in the same over time.

Structure

Analyzes the characteristics of a particular population, including the split:

• Sex / Age: We present average age pyramids, horizontal bar graphs representing: the x-axis (absolute figures or percentages of the total population, men and women) and the vertical axis (the different age groups, generally 5 to 5 years).
• Economic Activity: Distinction by economic sectors with the most basic division:
  • Primary: Livestock, agriculture, and fisheries, produce

Key Features of Islamic Architecture

Islamic architecture can be distinguished by several key characteristics:

• Buildings are often regularly sized.
• Brick and wood were the most commonly used building materials.
• Vaults and domes are frequently used, including ribbed vaults, honeycomb (muqarnas), and fluted domes.
• Pillars and columns serve as supporting elements.
• Various arch types are employed, such as the horseshoe, semicircular (half-point), pointed, and polylobed arches.
• Interiors typically feature rich decoration, often contrasting with simpler exteriors.

Islamic architecture can be broadly divided into religious and civil categories.

Islamic Religious Architecture

In religious architecture, the most important building is the mosque, a place created... Continue reading "Distinctive Elements of Islamic Architecture" »

Early Spanish Industrialization

The exploitation and trade of iron and coal from Biscay and Asturias eventually led to the development of the steel and mechanical industries. Concurrently, the cotton textile industry developed in Barcelona, alongside the wool industry in Sabadell, Terrassa, and Béjar.

Autarky and INI (1939-1959)

This period saw the imposition of a policy of autarky, which emphasized self-sufficiency and minimizing trade with foreign countries. The Instituto Nacional de Industria (INI) was created during this time.

Key Export Sectors During Autarky:

• Consumer Goods: Footwear, leather, cork, furniture, paper, and publishing.
• Basic Industries: Rubber, machinery, mining, and shipbuilding.

Regional Industry in 1975

Different regions developed... Continue reading "Spanish Industrial History and Regional Development" »

T14 5.1 Workforce

The workforce consists of the active population, including employed adults and those unemployed or seeking their first job. In Spain, this represents the active population, but only about 58% of the total population.

Employed active population accounts for over 58% of the total population.

Three Main Sectors:

1. Primary Sector: Employs a small percentage of the workforce (4.8%) and continues to decline.
2. Secondary Sector: While it created jobs, the workforce has decreased (29.6%). Some administrative roles have moved to other countries.
3. Tertiary Sector: Employs a large portion of the Spanish population and has diversified in recent years.

Unemployment rates in Spain are high due to a greater demand for work than job creation. In 1994,... Continue reading "Understanding Spain's Workforce, Immigration, and Murcia's Population" »

Columbus's Atlantic Crossing Proposal

Genoese sailor Christopher Columbus proposed a westward voyage across the Atlantic to reach the Spice Islands, aiming to bypass the traditional eastern routes around Africa.

Columbus's Voyages to the Americas

First Voyage: Reaching the New World (1492)

The first expedition, consisting of the flagship Santa Maria and two caravels, the Pinta and the La Niña, departed from the port of Palos de la Frontera. After a stopover in the Canary Islands, the ships crossed the Atlantic, sighting land on October 12, 1492. This was the small island of Guanahani in the Bahamas, which Columbus named San Salvador.

Later Expeditions by Columbus

The success of the first voyage led to the swift preparation of subsequent expeditions:... Continue reading "Columbus's Voyages: Dawn of a New World Era" »
