IB Geography F.5.2 Contrasts in the Scale of Causes and Solutions Notes

A Local Health Hazard Can Depend on National and Global Support

1. A cholera outbreak may begin at a contaminated well, pipe or drainage channel within one settlement.
2. Tracing the source, repairing infrastructure and distributing safe water require local knowledge and access.
3. National government may control laboratory capacity, emergency finance, water standards and public-health staff.
4. International agencies may supply funding, vaccines, technical guidance or logistics when national capacity is exceeded.
5. Media coverage can influence donor attention even though the physical source remains local.
6. The cause, evidence, authority and finance therefore operate at different scales.

Global Grain Shocks Become Household Food Crises Through Prices

1. Poor harvests, energy costs, conflict or export restrictions in major producing countries can reduce traded supply.
2. Import-dependent states then face higher costs even when their own harvest has not changed.
3. Governments may reduce tariffs, subsidise staples, release reserves or ration foreign exchange.
4. Traders pass some costs to consumers, while poor households switch foods, reduce portions or borrow.
5. Selling livestock or tools protects consumption briefly but weakens future earning capacity.
6. A global price shock can therefore create a local poverty trap through household coping decisions.

Global Marketing Meets National Regulation and Local Diets

1. A transnational food company can distribute the same brand and advertising strategy across many countries.
2. National governments set taxes, labelling rules, advertising restrictions and school-food standards.
3. Retail location, household income and cultural preference determine who encounters and buys the product locally.
4. A child-advertising restriction can reduce one route of influence without changing the wider supply of cheap processed food.
5. The outcome reflects interaction among global corporate reach, national regulation and local access.

Somalia in 2011 Shows Why Famine Cannot Be Explained at One Scale

1. Regional drought damaged crops and livestock across the Horn of Africa.
2. Armed conflict and restrictions on humanitarian access concentrated extreme outcomes in southern Somalia.
3. Household poverty and displacement reduced access to remaining food and safe water.
4. International funding and logistics influenced how much assistance could arrive and how quickly.
5. A drought-only explanation misses political access, while a conflict-only explanation misses the environmental shock.
6. The famine emerged from regional hazard, national and local governance, household vulnerability and global response.

Brazil Shows When a National Government Can Integrate Solutions

1. Brazilian hunger reflected unequal income and access within a country that produced large amounts of food.
2. National cash transfers, school meals and support for family farming could operate through one legal and fiscal system.
3. Municipal delivery translated national policy into payments, meals and services.
4. The strategy produced gains because the central state could coordinate several sectors at national scale.
5. Later reversal showed that national scale also concentrates vulnerability when budgets and political priorities change.
6. International learning may spread the model, but another country needs comparable administrative and fiscal capacity to reproduce it.

Scale Determines the Reach and Constraint of a Solution

1. Local action can fit community conditions but may lack finance or authority over wider causes.
2. National action can tax, regulate and redistribute but may ignore local exclusion or cross-border drivers.
3. Regional cooperation suits shared rivers, airsheds, disease surveillance and food markets that cross state boundaries.
4. Global action coordinates standards, research and finance but depends on states for implementation.
5. A multi-scalar solution is useful only when responsibility is clear and information moves between levels.
6. A strong judgement identifies the scale at which the dominant mechanism can actually be changed.
