EXAM TIP: When discussing climate change, always link the environmental impact to specific health and human development outcomes.

3. Conflict

3.1. Definition and Causes

• Conflict refers to armed struggles and disputes between countries or within countries.
• Causes can include political instability, economic inequality, ethnic tensions, and competition for resources.

3.2. Implications for Health and Human Development

• Direct injuries and death: Resulting from violence and warfare.
• Displacement: Forced migration due to conflict, leading to refugee crises.
• Destruction of infrastructure: Healthcare facilities, schools, and water systems are often targeted.
• Disruption of essential services: Reduced access to healthcare, education, and sanitation.
• Food insecurity: Disruption of agricultural production and supply chains.
• Increased risk of infectious diseases: Overcrowding, poor sanitation, and lack of access to healthcare.
• Mental health issues: Trauma, PTSD, and depression among affected populations.
• Human rights violations: Including sexual violence, forced labor, and recruitment of child soldiers.

APPLICATION: The Syrian civil war has led to a massive refugee crisis and a significant decline in health indicators within the country.

4. Mass Migration

4.1. Definition and Causes

• Mass migration refers to the movement of large groups of people from one place to another.
• Causes can include conflict, environmental disasters, economic hardship, and persecution.
• Refugees are people who have been forced to leave their country due to a well-founded fear of persecution.
• Asylum seekers are people who have applied for protection in another country but have not yet been granted refugee status.
• Internally displaced persons (IDPs) are people who have been forced to leave their homes but remain within their country’s borders.

4.2. Implications for Health and Human Development

• Overcrowding and poor sanitation in refugee camps and urban slums.
• Increased risk of infectious diseases: Due to poor living conditions and limited access to healthcare.
• Mental health issues: Trauma, stress, and depression related to displacement and loss.
• Discrimination and social exclusion: Migrants may face prejudice and barriers to accessing healthcare, education, and employment.
• Strain on healthcare systems in host countries.
• Food insecurity: Difficulty accessing adequate nutrition, especially for vulnerable groups like children and pregnant women.
• Loss of skilled workers in countries of origin, impacting economic development.

STUDY HINT: Create a table comparing the definitions of refugees, asylum seekers, and internally displaced persons.

5. Increased World Trade

5.1. Definition and Causes

• Increased world trade refers to the growing exchange of goods and services between countries.
• Driven by factors such as reduced trade barriers, technological advancements, and globalization.

5.2. Implications for Health and Human Development

• Global distribution and marketing of tobacco products and e-cigarette products:
  • Increased rates of smoking-related diseases (cancer, heart disease, respiratory illnesses).
  • Exposure to harmful chemicals and nicotine addiction, particularly among young people.
• Global distribution and marketing of processed foods:
  • Increased consumption of unhealthy foods high in sugar, salt, and fats.
  • Rising rates of obesity, diabetes, and cardiovascular disease.
  • Displacement of traditional diets and food systems.
• Economic growth and poverty reduction: Trade can create jobs and increase incomes, improving overall living standards.
• Access to medicines and healthcare technologies: Trade can facilitate the distribution of essential medicines and medical equipment.
• Environmental degradation: Increased production and transportation can lead to pollution and resource depletion.

COMMON MISTAKE: Don’t only focus on the negative impacts of increased world trade; remember to include the potential benefits for health and human development.

6. Tourism

6.1. Definition and Causes

• Tourism refers to the activity of people traveling to and staying in places outside their usual environment for leisure, business, or other purposes.
• Driven by factors such as increased disposable income, improved transportation, and greater awareness of different cultures.

6.2. Implications for Health and Human Development

• Spread of infectious diseases: Increased international travel can facilitate the spread of diseases like influenza, measles, and COVID-19.
