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

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" »

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" »

Franco's Spain: Economy and Social Change

In 1939, Spain was devastated. The Franco regime was modeled after Italy (Mussolini) and Germany (Hitler). These models emphasized state intervention and economic self-sufficiency (autorquía). The state controlled prices of agricultural products, compelling farmers to surrender their crops.

In 1941, the National Institute was established to control foreign commerce and industry.

Economic Failure in the 1940s

Agricultural production declined after the war, and the black market dominated the economy. The international isolation of the Franco regime worsened the situation.

The End of Autorquía (1950s)

Economic policy shifted in the 1950s. Prices were deregulated, and food rationing ended in 1952. Starting... Continue reading "Franco's Spain: Economy and Social Transformation" »

Toward the Contemporary World

At the end of the 18th century, certain movements in the economy overrode attempts at protectionism, which was based in most countries of old Europe. Industry was widely dispersed, operating in workshops, and the small textile industry was concentrated. After 1760, this process became known as the Industrial Revolution. This reform began in England, where the bourgeoisie controlled power, helping to transform agriculture. The Industrial Revolution marked the transition from a traditional agrarian economy to one marked by industry and machine production.

Demographic Revolution: Population Increases

Causes:

• Drop in mortality.
• Eradication of diseases (Black Death).
• Progress of personal and urban hygiene.
• Collection of garbage

Spain's Diverse Agricultural Landscapes

Agricultural landscapes represent the morphology of rural areas, a combination of the natural environment and agricultural activity. The diversity of these combinations explains the variety of existing agricultural landscapes.

The Agricultural Landscape of Wet Spain

This region comprises the north and northwest of the Iberian Peninsula, characterized by rugged terrain with few flat areas and wet oceanic climates throughout the year.

Agrarian Structure

Historically, a large population couldn't be supported by the land, leading to migration and an aging population today. Settlements are dispersed in villages and parishes.

Farmers own small plots (minifundismo) surrounded by hedges, decreasing profitability and... Continue reading "Spain's Agricultural Landscapes: A Regional Analysis" »
