Possible Solutions to Food Insecurity
Possible solutions to food insecurity, including waste reduction, evaluated through contrasting strategies and a named case study.
The original AdornGeo sequence begins by asking why food insecurity persists when the world produces enough food. Students compare supply-side strategies with approaches that improve access, distribution and resilience, then test them against the Rwanda case study. Food waste belongs inside this enquiry: reducing losses can increase effective supply without bringing more land into production.
- Separate food availability from access, utilization and long-term stability before proposing a solution.
- Supply-side responses include irrigation, improved seed, storage, transport, mechanization and agricultural extension.
- Access-side responses include income support, school meals, social protection, land rights, market access and emergency food assistance.
- Food is lost between farm and market where harvesting, refrigeration, storage or transport are weak; it is often wasted at retail and household stages in wealthier food systems.
- A strong evaluation identifies who benefits, the scale and time frame of the strategy, environmental costs and whether vulnerability is actually reduced.
Build a solution ladder
- Watch the original IB lesson and complete the original Possible Solutions activity embedded below.
- Sort each response into production, distribution, access, consumption or governance.
- For each response, identify its operating scale, likely time frame, stakeholders and one possible unintended consequence.
- Rank the strategies from short-term relief to long-term resilience and explain why a strategy may move position in a different place.
Follow one plate backwards
- Use the food-waste notes and FAO material to trace one meal from farm to household.
- Mark every stage where edible food may be lost or wasted and identify the reason.
- Design one intervention for producers, one for retailers and one for consumers.
- Write a judgement explaining how far waste reduction can improve food security without addressing poverty or conflict.

Rwanda: tackling food insecurity
Rwanda provides a located evaluation of agricultural intensification, nutrition programmes and international support in a densely populated, landlocked country where small farms, soil pressure and climate variability continue to shape food security.
- Locate Rwanda in East Africa and establish its landlocked position and high rural population density.
- Connect small landholdings, erosion, rainfall variability and market access to the four dimensions of food security.
- Distinguish emergency support from programmes that raise productivity, nutrition and resilience.
- Evaluate the role of the Rwandan government, FAO, farmers and communities rather than attributing change to one actor.
- Use evidence of progress alongside continuing vulnerability to reach a balanced judgement.
Contemporary Approaches to Food Production
Advantages and disadvantages of contemporary approaches to food production, including genetically modified organisms (GMOs), vertical farming and in vitro meat.
The original lesson moves from explanation to debate. Students become specialists in GMOs, vertical farming and in vitro meat, compare the claims made for each, and then respond to the proposition that contemporary agriculture will ensure future global food security. The geographical test is whether an innovation is accessible, appropriate and sustainable in contrasting places—not simply whether it can increase output.
- GM crops may raise yields, nutritional value, shelf life or resistance to pests, disease and drought, but ownership, seed cost, ecological uncertainty and public acceptance matter.
- Vertical farms can reduce land use, water use, pesticide use and food miles, while their capital and energy requirements limit where and what they can produce.
- In vitro meat may reduce land demand, slaughter and some environmental pressures, but energy use, production cost, regulation and cultural acceptance remain contested.
- Innovation diffuses unevenly because finance, infrastructure, skills, regulation, markets and attitudes vary between places.
- No technology addresses conflict, poverty, gender inequality or insecure entitlement by itself.
Three innovations, one evaluation framework
- Use the original debate resources below to create a fact file for GMOs, vertical farming and in vitro meat.
- For each, assess yield, water, land, energy, emissions, cost, accessibility, risk and public acceptance.
- Choose two contrasting places and predict which innovation would diffuse fastest in each; justify the geographic barriers and opportunities.
- Complete the original debate planner for the motion: Contemporary approaches to agriculture will ensure future global food security.

Prevention & Treatment of Disease
The merits of prevention and treatment in managing disease, including social marginalization, government priorities, means of infection and scientific intervention.
The surviving AdornGeo page uses HIV/AIDS to make prevention-versus-treatment a geographical argument. Scientific interventions matter, but their reach is shaped by stigma, income, gender, sexuality, migration, public policy and health-service access. Students should compare the two approaches while recognising that effective management normally combines them.
- Prevention can interrupt transmission through education, testing, condoms, harm reduction, PrEP and prevention of mother-to-child transmission.
- Treatment with antiretroviral therapy improves health and life expectancy and can suppress viral load so that sexual transmission does not occur.
- Stigma and criminalisation may discourage testing or care, making marginalization part of the disease geography.
- Government priorities determine funding, availability, confidentiality, sex education and support for affected groups.
- Evaluate cost, speed, equity, cultural acceptability, individual agency and long-term effectiveness rather than choosing a false either/or answer.
Map the barriers to effective management
- Watch the original IB lesson and use the Thailand, UNAIDS and Our World in Data evidence.
- Build a prevention–treatment continuum rather than two disconnected lists.
- Add barriers at individual, community and government scales, then show which groups may be excluded by each barrier.
- Use the original Prevention & Treatment activity to prepare an answer evaluating the merits of both approaches.
Media, language and stigma
- Compare an older media portrayal of HIV/AIDS with a current public-health message.
- Identify language or imagery that could intensify stigma and explain the geographical consequence for testing, reporting or treatment access.
- Rewrite the message so that it is accurate, inclusive and useful for a named audience.

Managing Pandemics
Managing pandemics, including the epidemiology of the disease, prior local and global awareness, international action and the role of media. One named pandemic case study.
Pandemics are spatial processes: a pathogen moves through networks, but exposure, vulnerability and capacity to respond are uneven. The original AdornGeo IB video provides the syllabus framework. Students then apply it to COVID-19, examining epidemiology, preparedness, international coordination and the contradictory power of media to inform, mobilize, stigmatize and mislead.
- Epidemiology asks where and when cases occur, who is affected, how transmission happens and which interventions alter the pattern.
- Prior awareness includes surveillance, research, preparedness plans, stockpiles and lessons from earlier outbreaks.
- Local action may include testing, tracing, isolation, vaccination, public communication and support for people unable to work or isolate.
- International action includes data sharing, WHO coordination, research collaboration, finance and vaccine or equipment distribution.
- Media accelerates public-health communication but also spreads misinformation and can intensify xenophobia or mistrust.
Read a pandemic as a changing map
- Watch the original IB lesson, then use the WHO dashboard and Our World in Data explorer to build a dated spatial narrative of COVID-19.
- Choose three dates and describe how the distribution, rate of change and apparent core areas differed.
- Annotate the narrative with changes in surveillance, variants, mobility, vaccination or reporting that affect interpretation.
- Explain why a map of confirmed cases is not a complete map of disease burden.
Pandemic management audit
- Create four evidence panels: prior awareness, local action, international action and media.
- For each panel, include one success, one limitation, one affected stakeholder and one located example.
- Add vaccine equity and unequal ability to isolate as geographical dimensions of the response.
- Write a final judgement identifying which factor most strongly shaped the uneven outcomes of the pandemic.

COVID-19: a global pandemic with unequal outcomes
COVID-19 demonstrates how rapid movement through global networks interacted with uneven preparedness, age structures, health systems, livelihoods, public trust and vaccine access. It is most useful as a comparative case study rather than a single global total.
- Initial outbreak recognition and international notification in late 2019 and early 2020
- Diffusion through air-travel and urban networks followed by community transmission
- Contrasting national and local interventions, including testing, mobility controls, masking and vaccination
- WHO coordination, research collaboration and unequal access to vaccines and equipment
- Media communication, misinformation, stigma and public trust
- Uneven health, social and economic impacts within and between countries
