Resource development explained
A resource is any aspect of the environment that can be used to meet human needs.
Read the full explanation
Resources are classified as stock (non-renewable, finite) or flow (renewable, continuous). Evaluating stock resources involves categorising them by geological certainty: measured reserves (highly certain), indicated reserves, inferred resources, and possible resources (least certain). Resource development progresses through exploration, exploitation, and development. As accessible resources deplete, extraction moves to the resource frontier—remote or challenging areas like the Arctic. Finally, resource peak refers to the point in time when the maximum rate of extraction is reached, after which production enters terminal decline, as seen in Peak Oil theories.
Sustainable resource development. Environmental Impact Assessment (EIA) in relation to resource development projects.
Sustainable resource development balances current economic and social needs for resources with the preservation of the environment for future generations. This requires careful management of extraction and processing to minimise ecological degradation. An Environmental Impact Assessment (EIA) is a crucial statutory tool used to evaluate the potential positive and negative environmental consequences of a proposed resource development project before it begins. For example, before opening a new copper mine, an EIA would assess potential water contamination, habitat destruction, and air pollution, proposing mitigation strategies such as water recycling systems or post-extraction land rehabilitation to ensure the project aligns with sustainability goals.
Your focus
- Classify resources into stock and flow categories with appropriate examples.
- Evaluate stock resources using the continuum of measured, indicated, inferred, and possible categories.
- Explain the concepts of resource frontiers and resource peak in the context of global resource development.

- Evaluate the role and effectiveness of EIAs in managing the impacts of resource development projects.
Resource development exam tips
Marking Points
- Define stock resources as finite and non-renewable, and flow resources as renewable and continuous.
- Distinguish between the four levels of stock resource evaluation based on geological certainty and economic viability.
- Explain the chronological stages of resource development: exploration, exploitation, and development.
- Apply the concepts of the resource frontier and resource peak to specific examples, such as deep-water oil drilling or global coal production.
- Define sustainable resource development as meeting present needs without compromising future generations' ability to meet theirs.
- Explain the purpose of an EIA in identifying and evaluating the environmental, social, and economic impacts of a project prior to decision-making.
- Describe the stages of an EIA, including screening, scoping, baseline studies, impact prediction, and mitigation planning.
- Evaluate the effectiveness of EIAs, noting that while they mandate mitigation, they can sometimes be influenced by economic pressures or lack strict enforcement.
Examiner Tips
- 💡Use a specific example, such as oil or coal, to illustrate the transition from measured reserves to possible resources.
- 💡When discussing the resource frontier, include the environmental and economic costs associated with operating in extreme environments.
- 💡Be prepared to draw or interpret a Hubbert curve to illustrate the concept of resource peak in an exam.
- 💡Use a specific case study of a resource development project to illustrate how an EIA influenced its planning or mitigation strategies.
- 💡When evaluating EIAs, discuss both their strengths in preventing ecological damage and their limitations, such as cost and potential bias.
- 💡Link the concept of sustainable resource development to broader geographical themes like the circular economy or planetary boundaries.
Common Mistakes
- Confusing 'reserves' with 'resources' in stock evaluation. Correction: Remember that reserves (measured, indicated) are economically and technically viable to extract, whereas resources (inferred, possible) may not be.
- Using 'resource peak' to mean the point when a resource runs out completely. Correction: Define resource peak as the point of maximum production rate, not the point of total depletion.
- Failing to distinguish between the stages of exploration and exploitation. Correction: Clearly separate exploration (searching and assessing) from exploitation (the actual extraction and use).
- Confusing an EIA with an environmental audit; an EIA is conducted before a project begins, whereas an audit evaluates ongoing or completed operations.
- Assuming EIAs only consider environmental factors; they must also evaluate social and economic impacts on local communities.
- Believing an EIA guarantees a project will be sustainable; an EIA only informs decision-makers and proposes mitigation, but a project may still proceed with significant impacts.
