The Bronze Age in Spain

The Bronze Age in Spain, also known as the MegaLoad period, is characterized by the discovery of bronze, an alloy of copper and tin. This discovery allowed the manufacture of stronger utensils and weapons. The use of this new metal produced social differences, as shown by the funerary offerings found in tombs. The most representative cultures of this stage are Los Millares and El Argar.

At the end of the second millennium BC, the El Argar culture gradually disappeared, marking the beginning of the final period of the Bronze Age. The area received numerous influences from within. The chief influence would come from the kingdom of Tartessos at the mouth of the Guadalquivir River.

Spain's Migration Story: A Historical Overview

Since 1975, Spaniards, including young and old, skilled and unskilled workers, have traveled for various reasons, not necessarily from rural areas to cities. Currently, residents of Spanish autonomous communities move as tourists or for second homes, among other reasons.

Emigration from Spain: Historical Waves

Spain's history is marked by significant emigration patterns:

• Pre-1853: Bourbon political populism somewhat reduced emigration to America.
• 1853-1914: A significant shift occurred, leading to an increase in transoceanic emigration.
• 1914-1945: Transoceanic migration declined due to the paralysis caused by the World Wars.
• 1945-1960: Transoceanic migration recovered, largely thanks to the Franco regime'

Environmental Science: Understanding Ecosystems

The natural world is organized into interrelated units called ecosystems. An ecosystem is formed by a physical environment, characterized by environmental factors such as temperature, humidity, and salinity, along with living organisms that form a community, and the relationships established between them. Humanity obtains resources from ecosystems, and as a result, produces alterations or impacts on the environment. In turn, human beings are subject to risks arising from natural processes, such as a hurricane, or those resulting from human activities, such as traffic accidents or pollution.

Cultural Evolution of Indigenous Peoples in Venezuela

While the indigenous peoples located in what is now the territory of Venezuela may not have attained the same degree of development as other American cultures like the Mayas, Aztecs, or Incas, their evolution is still evident. Aboriginal communities in Venezuela experienced a gradual development through the exchange of techniques between different groups.

Stages of Cultural Development

Agricultural Training

This stage, between 1500 and 1000 BC, consisted of small communities of hunters, fishermen, and gatherers of wild fruit and seashells.

Beginning of Agricultural Activity

Around 1000 BC, communities began combining hunting, fishing, and gathering with the rudimentary cultivation of wild fruits,... Continue reading "Cultural Evolution and Indigenous Areas of Venezuela" »

Essential Historical Terms and Institutions

Manor Court Functions and Rights

The Manor Court refers to the prerogatives of the lord, a fundamental collection of manorial rights that encompassed political and judicial functions. Owners of manor courts often assumed the functions of the king within their domain.

Social Strata: Feudalism and Old Regime

An Establishment was a stratum of society defined by a common lifestyle or similar social function. Social division responded to the specific criteria of Feudalism and the Old Regime, with each establishment having a distinct role in society.

Crown Lands: Royal Judicial Authority

Lands of the Crown referred to judicial qualifications, meaning places directly under the king's authority. These were courts... Continue reading "Key Historical Terms: Medieval & Feudal Institutions Defined" »

Population Dynamics

Vegetative Growth

The difference between birth and mortality rates. Various metrics measure factors related to the natural movement of a population.

Population Density

The relationship between the number of inhabitants and the surface area (in square kilometers) they occupy.

Labor Force

The group of people aged 16 and over who are available to supply labor for the production of goods and services and are actively seeking employment.

Unemployment Rate

The percentage of the workforce that is unemployed relative to the total active population.

Migration

The movement of a population in space; the departure of people from their place of origin.

Immigration

A movement of population; the arrival of people at their destination.

Internal Migration

Developed... Continue reading "Population Dynamics and Urbanism: Key Concepts" »

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" »
