Lydora’s cities dispose of most household waste in landfills. Residents living nearby experience unpleasant odours and polluted groundwater. The government proposes a circular economy strategy based on reducing waste, repairing products, reusing materials and recycling.
Households will receive separate collection bins, while manufacturers will pay a charge related to the packaging they produce. Recycling firms will receive temporary subsidies for new equipment.
The strategy could create formal employment and reduce imports of raw materials. However, higher packaging costs may increase consumer prices. Informal waste collectors fear losing their livelihoods unless they receive training and access to formal jobs.
The government argues that equity requires the costs and benefits of environmental policy to be distributed fairly. It is considering free bins for low-income households.

Costa Verde is a middle-income economy whose coastal wetlands support fishing, flood protection and wildlife. The government wants to promote sustainable development by expanding nature-based tourism while conserving these ecosystems.
A new boardwalk and visitor centre have increased tourist demand. Hotels and restaurants have created employment, but untreated wastewater and disturbance from boat tours impose costs on fishing communities. The government is considering a pollution tax and limits on visitor numbers.
The visitor centre was partly financed by foreign borrowing. Supporters argue that tourism revenue can fund education, sanitation and wetland restoration, contributing to several Sustainable Development Goals (SDGs).
Critics argue that the project has an opportunity cost and that many tourism jobs are seasonal. They also fear that current residents will receive the income while future generations inherit damaged wetlands.

Many rural communities in Aridia have no reliable electricity. The government subsidizes solar mini-grids to improve refrigeration, evening study and access to digital markets. It describes electricity access as an important part of economic well-being.
Solar installation creates skilled employment and reduces the use of diesel generators. However, imported batteries are expensive and their disposal may contaminate soil and water.
The programme may support SDGs concerning clean energy, education, health and decent work. These complementarities illustrate interdependence, since progress in one area can affect several other economic, social and environmental outcomes.
The subsidy has a fiscal opportunity cost. Some urban taxpayers question why rural users receive support, while rural households argue that high connection charges would exclude low-income families.
Rural household electricity access in Aridia before and after the solar mini-grid programme.
| Measure | Before programme (households) | After programme (households) |
|---|---|---|
| Rural households | 360 000 | 360 000 |

Pelagos has experienced more frequent coastal flooding. The government plans to restore dunes and seagrass beds that protect homes, provide fish habitats and absorb carbon. These benefits contribute to environmental protection and social progress.
Restoration will temporarily restrict access to part of the beach. Tourism businesses expect lower revenue during construction, while fishers expect larger catches once habitats recover.
The project is financed by a coastal levy and international grants. Supporters argue that intergenerational equity requires current users to help preserve ecosystem services for future residents.
Opponents prefer a concrete sea wall, which would be completed faster. Scientists warn that it could transfer erosion to neighbouring beaches and provide fewer benefits for biodiversity.
Expected annual flood losses in Pelagos under two coastal-protection scenarios.
| Scenario | Expected annual flood losses / million pelars |
|---|---|
| Without restoration | 96 |
| After restoration | 60 |
Project finance for coastal restoration in Pelagos.

Norvia will require new homes to meet strict energy-efficiency standards. Better insulation lowers household energy consumption and urban emissions. The regulation is intended to promote sustainability, a condition in which economic, social and environmental systems can support well-being over time.
Construction firms expect higher initial costs. The government will subsidize training for builders and offer targeted grants to low-income homebuyers.
Energy-efficient homes have lower running costs and may improve health by reducing dampness. However, higher construction prices could reduce housing affordability and employment during the transition.
The government faces scarcity because funds used for housing grants cannot also finance every proposed school and hospital project. Officials argue that future energy savings justify the present cost.
Annual household energy use by type of new home.
| Type of new home | Annual energy use / kWh |

Rainfall in Sanjara has become less predictable. The government proposes reservoirs and drip-irrigation networks to stabilize food production, conserve water and increase rural incomes. This illustrates the three connected dimensions of economic development, social progress and environmental protection.
Reservoir construction will create jobs and electricity but flood some habitats and require 900 households to relocate. Farmers receiving irrigation will pay a usage charge.
Environmental groups prefer smaller rainwater-harvesting systems. They argue that large reservoirs encourage water-intensive crops and may not be suitable in every region.
Officials state that the programme supports several SDGs, but accept that its opportunity cost includes other health and education projects. Compensation and community participation may reduce social costs.
Water used to produce one tonne of agricultural output in Sanjara.

Nomadic households in Karumo share grazing land. Falling income and livestock disease have encouraged families to keep larger herds as insurance against future losses. The pasture is being used faster than it can regenerate.
Overgrazing reduces vegetation, increases erosion and lowers future livestock productivity. This threatens sustainability and may intensify rural poverty.
The government proposes community grazing permits, veterinary services and payments to households that restore vegetation. Secure community rights may improve incentives, but powerful herd owners could capture the permits.
Officials emphasize equity, arguing that households with few animals should not bear the same adjustment cost as wealthy commercial producers.

Shrimp exports have raised incomes in Talora’s coastal region. Low-income households clear mangroves to construct ponds because formal jobs and affordable credit are limited.
Mangrove loss reduces fish nurseries, carbon storage and storm protection. Development based on continued clearance may violate intergenerational equity.
The government proposes a per-unit tax on shrimp produced using newly cleared mangrove land, payments for ecosystem protection and loans for intensive shrimp ponds on already-cleared land. Its aim is to break the poverty-environment cycle rather than criminalize poor households.
The programme depends on international finance, illustrating interdependence because seafood consumption, climate effects and financial resources cross national borders.
Mangrove cover in Talora’s coastal region over five years.

Many low-income households in Endala earn income by producing charcoal from an open-access woodland. The woodland is a common-pool resource because excluding users is difficult and one person’s use leaves less timber for others.
Households know that deforestation lowers rainfall retention and soil quality, but they lack affordable electricity, credit and alternative employment. Immediate food needs therefore encourage continued tree cutting.
The government proposes clean-cooking subsidies, microcredit for rural enterprises and community forestry rights. These policies aim to weaken the relationship between poverty and environmental degradation.
Commercial charcoal traders oppose tighter quotas. Conservation groups support them but warn that restrictions without alternative incomes could deepen poverty and encourage illegal production.

Rising demand for rechargeable batteries has expanded artisanal cobalt mining in Belesia. Mining provides income in a poor region, but tunnel collapses, child labour and polluted streams reduce economic well-being.
Miners often lack credit and safer equipment. Because immediate income is needed for food, they continue mining despite declining land and water quality. Pollution is a negative externality of production.
The government proposes safety training, school-income grants, pollution charges and certification of responsibly produced cobalt. Foreign battery firms may pay a higher price for certified output.
Supporters link the proposal to the Sustainable Development Goals (SDGs) for poverty, education, decent work and responsible production. Critics fear that costly certification will exclude the poorest miners.
Cobalt prices and annual certified sales for a cooperative.

Poor tenant farmers in Oranta cultivate steep hillsides because fertile valley land is concentrated among a few owners. Short leases provide little incentive to construct terraces or plant trees.
Erosion lowers future yields and deposits sediment in a hydroelectric reservoir. These effects reduce economic well-being and impose costs on electricity users.
The government proposes longer, legally protected leases, subsidized conservation loans and agricultural training. It argues that secure rights could encourage investment while loans improve access to technology.
Critics argue that indebted farmers remain vulnerable to crop failure. They call for grants and land redistribution to improve equity, although these policies face political opposition.

Thousands of low-income workers in Varelia recover valuable metals from discarded electronic goods. Burning cables provides immediate income but releases toxic smoke and contaminates soil.
Workers lack protective equipment, credit and access to safer machinery. Poor health lowers productivity and reinforces poverty. The unregulated allocation therefore creates market failure.
The government proposes producer responsibility charges, licensed recycling centres, free safety training and guaranteed purchasing of materials collected by registered informal workers.
Officials describe this as sustainable development because it seeks to improve employment, health and environmental protection without transferring toxic damage to future generations. Some firms warn that the charge will raise electronics prices.
Annual electronic waste generated and safely recycled in Varelia.
| Measure | Electronic waste / tonnes per year |
|---|---|
| Generated annually | 300000 |
| Safely recycled currently | 54000 |
| Safely recycled under target | 135000 |
Worker transition programme in Varelia
| Eligible workers / workers | Training cost / varels per worker | Protective equipment / varels per worker |
|---|---|---|
| 30 000 | 140 | 60 |
Define the term market failure indicated in bold (Text A, paragraph 2).
Define the term sustainable development indicated in bold (Text B, paragraph 2).
Using Table 1, calculate the current safe-recycling rate and the target safe-recycling rate.
Using Table 2, calculate the total cost of training and protective equipment for all eligible workers.
Using a negative production externality diagram, explain why informal electronic-waste recycling may cause market failure (Text A).
Using a demand and supply diagram, explain how producer responsibility charges may affect the market for electronic goods (Text B).
Using a poverty-cycle diagram, explain how unsafe informal recycling may reinforce poverty (Text A).
Using a labour market diagram, explain how licensed recycling centres and training could affect formal employment (Text B and Table 2).
Using information from the texts/data and your knowledge of economics, evaluate Varelia’s proposed inclusive recycling system as a strategy for reducing poverty and improving sustainability.

Torland intends to replace part of its coal-generated electricity with solar electricity. The transition is expected to reduce greenhouse-gas emissions but will increase demand for minerals extracted in a low-income region of the country. Mining provides employment and government revenue, but it also pollutes water used by nearby communities.
Table 1 presents electricity-generation data.
Electricity-generation data for Torland's planned replacement of coal generation with solar generation.
| Measure | Coal | Solar | Unit |
|---|---|---|---|
| Annual generation replaced | 400 | 400 | GWh per year |
| Life-cycle emissions | 0.90 | 0.05 | tonnes per MWh |
| Generation cost | 60 | 85 | LCU per MWh |
| External benefit of avoided emissions | 50 | 50 | LCU per tonne |
| Conversion factor |
Table 2 presents information about the environmental costs of mineral extraction.
Mineral extraction and water-remediation information for the solar programme in Torland.
| Measure | Value |
|---|---|
| Ore required for solar programme | 200 000 tonnes |
| Estimated marginal external cost | 12 LCU per tonne of ore (assumed constant over the 200 000 tonnes required) |
| Water-remediation fund contribution | 1 500 000 LCU |
Define the term intergenerational equity.
Calculate the annual reduction in life-cycle emissions resulting from the replacement of coal generation with solar generation.
Calculate the annual net social benefit of the replacement, considering only the additional generation cost and the external benefit from avoided emissions.
Using Table 2, calculate the total external cost of mineral extraction and the amount by which this exceeds the remediation fund.
Draw a negative production externality diagram for mineral extraction, showing the market quantity, socially efficient quantity and welfare loss.
Explain two trade-offs between Sustainable Development Goals that may arise from Torland's energy transition.
Using the text/data provided and your knowledge of economics, recommend a policy that would enable Torland to expand renewable electricity while limiting the environmental and social costs of mineral extraction.
Small-scale farmers in Kambara cultivate land affected by erosion and declining soil fertility. Many farmers lack secure land rights and cannot obtain affordable credit for soil-conservation equipment. The government is considering credit guarantees and payments for ecosystem protection.
Table 1 presents information about the proposed credit programme.
Proposed credit-guarantee programme in Kambara.
| Programme feature | Value |
|---|---|
| Number of farmers receiving loans | 1 000 farmers |
| Loan per farmer | 600 LCU |
| Expected default rate | 10% of borrowers |
| Government guarantee | 80% of principal lost through default |
| Assumption for defaulting borrowers | Full principal is lost; interest ignored |
Table 2 compares crop yields and gives data for the proposed ecosystem-protection payments.
Crop-yield trends and proposed ecosystem-protection payment data in Kambara.
| Measure | Value | Unit / basis |
|---|---|---|
| Conventional farming yield (current) | 2.50 | tonnes per hectare |
| Conventional yield change | Decrease of 4% | each year |
| Sustainable farming yield | 2.40 | tonnes per hectare |
| Sustainable yield change | No change | each year |
| Ecosystem-protection payment | 35 | LCU per hectare per year |
| Land covered by payments | 2 000 | hectares |
| Downstream water-treatment savings | 90 000 | LCU per year |
Define the term equity.
Calculate the expected cost to the government of the credit guarantee.
Calculate the conventional farming yield after three years and the difference between this yield and the sustainable farming yield.
Calculate the annual cost of the proposed ecosystem-protection payments and the net annual benefit after accounting for downstream water-treatment savings.
Draw a poverty-environment cycle showing how low income can contribute to soil degradation and how soil degradation can reinforce poverty.
Explain how secure and equitable land rights could improve both poverty reduction and environmental sustainability in Kambara.
Using the text/data provided and your knowledge of economics, recommend a policy that the government of Kambara should use to promote sustainable agriculture while reducing rural poverty.
