Demographic Transition Model and Population Structure Analysis
Demographic Transition Model
This model explains the evolution of a population through various phases based on demographic indicators:
Initial Phase (Late 18th Century)
Characterized by high birth rates and high mortality rates, resulting in low population growth.
Transition Phase (19th – Early 20th Century)
Currently seen in some underdeveloped countries. The mortality rate drops while the birth rate remains high. Subsequently, both indicators decrease, and natural growth is reduced.
Late Transition
Demographic Transition Stages and Global Population Dynamics
Phases of Demographic Transition
Phase 2: Early Expanding
The birth rate remains fairly high because children are still considered a necessity. This phase corresponds to when the United Kingdom industrialized. There is tremendous population growth during this stage.
Phase 3: Late Expanding (Containment, 1880 – Pre-World War I)
This marks the final step towards an urban, industrial society. The death rate continues downhill, reaching approximately current levels due to medical advances like penicillin,

Oceanic Agricultural Landscape
Located in the north and northwest of the Iberian Peninsula, this landscape is characterized by rugged terrain and a maritime climate. Plots are typically small and enclosed with hedges.
Land Uses
Land use is mainly livestock-focused, though many farms practice mixed land use, combining livestock with agricultural and forest areas.
Agriculture
- Specializes in garden crops for human consumption and fodder plants.
Livestock
- This is the most significant agricultural activity,
Economic Modernization and Industrial Change in Spain
Liberalism and Capitalist Economy Emergence
After Fernando VII’s death, a historical period began where Spain underwent significant economic changes, entailing the country’s progressive modernization. During these decades, the economic aspects of the Antiguo Régimen (Old Regime) – an archaic economy based on agriculture – disappeared, giving way to liberalism. A new capitalist economy emerged where industry, trade, and capital took center stage. This progress occurred during the Regencies of

Benefits of Biodiversity for Local Residents
The sustainable use of biodiversity offers an opportunity to improve the living conditions of inhabitants. To ensure success, countries must react quickly and implement effective policies and strategies. A clear principle should prevail: “First is the people,” meaning efforts should be directed to improve the economic and human well-being of settlers.
It is known that rural populations are great conservators of biodiversity, especially genetic resources.
