Agricultural Practices
Transgenic Crops
Genetically modified plants with altered genes, often to enhance properties like pest resistance and yield.
Sharecropping
Indirect land ownership where the landlord receives a portion of the harvest in exchange for land use. Primarily practiced in Menorca (Balearic Islands), sharecropping is declining in favor of leasing to improve farmers’ economic solvency.
Monoculture
Cultivation of a single dominant plant species in a region. This system enables high mechanization

European Regional Policy
European regions have varying population and production levels, leading to inequalities. To address this, the EU established a regional policy, utilizing Structural and Cohesion Funds from its annual budget. Initially, Spain and Portugal’s regions were less developed and received substantial funding. However, post-2004, with Eastern European countries joining, funds were redirected to their less developed regions.

New Forms of Capitalism: Industrial Expansion
Great Britain dominated the global economy until 1870, with London as the financial capital. Its population tripled, mostly living in large cities. Britain maintained its hegemony until 1914. Other nations like Italy, Russia, Spain, Germany, Sweden, Belgium, and Holland followed. By 1871, Germany’s political unification led to rapid industrial growth, fueled by advanced technology and state-supported banking. This made Germany a leading European power,

Egypt, the Nile, and the Desert
Egypt’s geographical location offers two advantages:
- The desert separates it from enemies.
- The Nile provides flood irrigation and fertilization, enabling farmland.
In the 5th and 4th millennia BC, climate changes and water shortages led tribes to the Nile’s banks.
The Flooding of the Nile
From June to September, the Nile rises due to spring rains at its source, flooding the riverbanks. The water recedes in September, leaving behind fertile black silt. The flooding posed

Energy Sources in Chile
Chile possesses diverse energy sources, categorized by renewability and origin.
Primary Energy
Primary energy refers to natural resources used directly or indirectly for energy, including:
- Renewable: Hydropower (rivers, waves), solar, wind.
- Non-renewable: Oil, coal, geothermal, nuclear.
Primary energy is extracted or captured without transformation.
Secondary Energy
Secondary energy results from transforming primary sources, such as:
- Electricity
- Petroleum products (gasoline, diesel)
