**Spanish Urban Hierarchy**

The Metropolis

Cities at the top of the urban hierarchy are considered metropolises. Their population exceeds 250,000. They perform specialized functions related to the tertiary sector and industry. Within the metropolis, there is a hierarchy of functions based on size and scope of its area of influence.

National Metropolis

Madrid and Barcelona are considered national metropolises. Their population exceeds 4 million. Their area of influence extends throughout the country, acting as a liaison between the European urban system on a global scale and the local Spanish system.

Regional Metropolises

These are the metropolitan areas of Malaga, Bilbao, Seville, Valencia, and Zaragoza. They have a population between 500,000 and... Continue reading "Urban Hierarchy in Spain & European Integration" »

Urban Structure

Urban structure refers to the division of a city into areas with distinct characteristics in terms of morphology and function.

Old Town

The old town represents the legacy of the pre-industrial era. It is the part of the city that existed before industrialization. Pre-industrial cities often share common characteristics:

• Irregular Layout: The street layout was often irregular, although some examples of flat, linear, or grid patterns also exist.
• Walled Enclosures: Most were surrounded by walls for defense, taxation, and health purposes.
• Closed Plots: Buildings were predominantly low-rise.
• Mixed Land Use: Different activities were intermingled, although some neighborhoods specialized in certain activities.
• Social Stratification: Various

The Plateau

The Plateau is a high-altitude morphostructural unit that constitutes half of the peninsular relief units. Extensive plains alternate with hilly areas. The Alpine Orogeny caused the slope of the plateau towards the Atlantic Ocean. The Central System divides the plateau into two: the Northern Sub-Plateau and the Southern Sub-Plateau. These subunits were formed during downhill movement.

The Northern Sub-Plateau

It is situated within the northern half of the peninsula. Bordered to the northwest by the Galician-Leonese Massif, on the north by the Cantabrian Mountains, east by the Iberian System, and west by the gorges of the Douro and its tributaries. Its average altitude is 750m and it is crossed by a network of rivers, primarily the... Continue reading "Spain's Central Plateau: Formation and Features" »

The 1920s: International Landscape

The early postwar years were characterized by:

• A lack of international cooperation.
• Protectionist policies.

The Dawes Plan, implemented in 1924, aimed to improve the European economy, specifically by normalizing the German economy through:

• Stabilizing the German currency.
• Regulating the payment of war reparations.
• Having Americans help revive the German economy.

Germany created a new currency.

U.S. Economic Growth: Features

• Increased production and lower prices.
• Promotion of new industrial sectors.

The Situation in Europe

• France: Industrial growth.
• United Kingdom: Economic stagnation.
• Germany: Crisis until 1925, followed by subsequent recovery.

The Crisis of 1929

Causes

• Crisis in the industrial and construction sectors.
• Increased

Road Transport in Spain

Road networks in Spain have different characteristics. Historically, radio network design was present radially, maintaining a centralist state that favored the connection of the capital and principal towns. The skills enable ECN. The road network is divided between the State, the autonomous communities, and councils.

• The state network includes general-interest itineraries.
• Autonomous communities handle intraregional mobility and links.

The technical nature of state roads is varied. State roads often receive assistance from local councils and provincial governments. A weakness of road transport is that it receives most traffic of passengers and goods, and is less price competitive because there is a direct relation between...

Cultural Change 13.3: Shifting Mindsets

Education and the Press

From the late 19th to early 20th centuries, Spain experienced significant economic, social, political, demographic, and cultural advancements. Between 1874 and 1914, Spain's per capita income grew by 60%, with notable industrial and railway expansion.

Politically, the recognition of universal suffrage expanded voting rights, consolidating individual freedoms. Socially, the rise of the middle class and urban growth were evident. Madrid's population surpassed 500,000, and Bilbao's grew from 30,000 to 85,000. Citizens increasingly mobilized through labor unions, employers' associations, feminist groups, farmers' leagues, chambers of retailers, sports clubs, and cultural organizations....

Climate and Landscapes: An Introduction

This document explores various climate zones and their associated landscapes.

1. Climate Seasons

• Winter: Areas influenced by polar air masses.
• Summer: Areas affected by hot air masses.
• Intermediate Seasons: Spring and Autumn.

2. Temperate Zone Landscapes

These include:

• Oceanic or Atlantic
• Mediterranean
• Continental

3. Cold Weather Landscapes

Found in polar regions and high mountains. Shrubs and higher vegetation grow in these areas. Polar regions are sparsely populated.

4. Landscape Types

Oceanic Landscape

Characteristic of the west coast of Europe. The oceanic climate features mild winter and summer temperatures. Rainfall is abundant throughout the year. Forests and meadows thrive in this environment.

Mediterranean Landscape

Found... Continue reading "Temperate, Cold, and Mediterranean Landscapes: Climate and Vegetation" »

Sustainability and Water Use

If we use water faster than it can be replenished, its use is not sustainable. We need to store and distribute it efficiently, which can be expensive.

Large-Scale Water Management Projects

Large-scale projects to increase water supply often involve big dams. They are usually complex, multi-purpose projects. Up to the 1980s, the rate of building increased until most of the best sites in North America and Europe had been developed, in the so-called 'Blue Revolution'.

Currently, dams supply:

• 40% of the world's irrigated water.
• 20% of the world's electricity.
• 15% of all blue water.

Dams may bring benefits in terms of increased water supply, but they can have negative impacts too. Their construction can disrupt fragile aquatic... Continue reading "Water Management: Sustainability, Pollution, and Solutions" »

Castile: Medieval Political Structure

Castile's political structure centered on three institutions. The monarchy was authoritarian, with farmers dependent on it. Castile and Leon unified administration, focusing on establishing a general law, the Code of the Party, and centralizing power. Alfonso X strengthened the royal case against former privileges. The monarchy could legislate without the Cortes, which arose from the bourgeoisie's desire to participate in government. The Cortes, an assembly of nobles, clergy, and bourgeoisie, had a consultative role and approved subsidies. Municipalities enjoyed autonomy and their own jurisdiction, subject to open meetings. The figure of the mayor, the royal representative in municipalities, emerged.

Economic Activity

Economic activity is the means by which we obtain the products and services to cover our needs. It involves several phases:

• Production: The generation of goods and services.
• Distribution: The allocation of goods and services.
• Consumption: The acquisition of products to meet needs.

Economic Sectors

• Primary Sector: Agriculture, livestock, fishing, and forestry.
• Secondary Sector: Economic activities that transform raw materials into manufactured products.
• Tertiary Sector: A variety of activities that do not produce tangible goods.
• Quaternary Sector: Research, design, management, and development.

Economic Agents

• Families: Involved in production, providing labor and consuming goods and services.
• Enterprises: Produce goods and services for
