Mesopotamia: Cradle of Civilization and Empires
History
Mesopotamia is considered one of the birthplaces of civilization, as it was in Lower Mesopotamia where the first civilizations emerged around the sixth millennium BC. The first cities were the culmination of a sedentary population and an agricultural revolution, which originated during the Neolithic Revolution. Humans were no longer collectors who depended on hunting; natural resources offered a new form of environmental matters, a possible cause of the outbreak of urban Mesopotamia.
Iberian Peninsula: Relief, Climate, and Rivers
Relief
The rocky Iberian Peninsula can be divided into three areas: siliceous, limestone, and clay.
The siliceous area consists of ancient Precambrian rocks, primarily located in the western peninsula (Galicia, Leon, Extremadura, and most of Portugal). Granite is the predominant rock. This area also includes remains of ancient massifs, such as in the Pyrenees, Iberian and Catalan Coastal Range, and the Penibetic system.
The limestone area consists of secondary sediments folded during the Tertiary.

1. Urban Population Dynamics
1.1. The Rise of Urban Populations
Traditional societies were primarily rural, while modern society is fundamentally urban. In 1900, only 10% of the global population resided in cities. By 2003, this figure reached 48%, and it is projected to hit 61% by 2030. Megacities like Tokyo, Mexico City, New York, São Paulo, and Mumbai continue to expand, with urban populations, particularly in Asia and Africa, expected to increase significantly.

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.
