IB ESS SL 3.3 Conservation & Regeneration Paper 1 & 2 Core idea ~12 min read

Competing Views on Conservation

Two people can agree completely that a species should be saved and still argue bitterly about how. That is not stubbornness — it is because they hold different environmental value systems, and those values point towards different strategies. This page is where 1.1 comes back and does real work.

📚 What you need to know

How value systems shape strategy

Two value systems, two shopping lists the same goal, reached in very different ways ECOCENTRIC nature has value in itself intrinsic value of nature low-intervention in situ wilderness reserves let ecosystems self-manageANTHROPOCENTRIC value comes from use to people economic and social value zoos and gene banks captive breeding ecotourism and researchTwo value systems, two very different lists of preferred strategies. Most real programmes sit somewhere between the two.
Neither column is the correct one. Where a person sits on this spectrum decides which strategy looks obvious to them, which is exactly why conservation arguments are so hard to settle.

Ecocentric perspectives

Anthropocentric and technocentric perspectives

A neat way to test which perspective an exam scenario reflects: ask what is being counted. If success is measured in visitor numbers, revenue or animals bred, the framing is anthropocentric. If it is measured in habitat left undisturbed, it is ecocentric. Then say so explicitly — naming the value system is usually worth a mark on its own.

What makes conservation succeed

Five things a project needs missing any one of them is usually why projects fail COMMUNITY local support and volunteersFUNDING money for projectsEDUCATION public awarenessLEGISLATION laws that protectRESEARCH evidence to guide choicesConservation fails on any one of these, not just on ecology. Add environmental justice: who gains and who bears the cost.
Only one of these five is a biological factor. The rest are social, political and financial — which is exactly why this is ESS and not just ecology.
FactorWhat it involvesExample
Community supportEngaging local communities and recruiting volunteers to help complete projectsSnowdonia National Park Authority partnering with local farmers in Wales to manage and conserve the upland landscapes of Eryri
Adequate fundingSecuring the financial resources a project needs, and keeping them over the long termThe National Lottery Heritage Fund supporting biodiversity conservation projects across the UK
Education and awarenessRaising public understanding of conservation issues so support and behaviour change followMillions watching the BBC’s Blue Planet II, which highlighted plastic pollution in marine ecosystems
Appropriate legislationLaws and regulations giving legal protection to species and habitats, plus the means to enforce themThe Wildlife and Countryside Act 1981 in the UK
Scientific researchEvidence to inform decisions and to check whether strategies are workingThe British Trust for Ornithology’s research on bird populations guiding conservation effort
Why community support usually decides it. A reserve can have funding, laws and excellent science and still fail if the people living around it see it as something imposed on them. Conversely, communities with a stake in a project will protect it long after the funding runs out. If a question asks which factor matters most, this is a defensible answer — provided you justify it.

Environmental justice in conservation

This is procedural justice from 1.3 again, and it explains a lot of conservation failure. Projects that excluded local and indigenous people, sometimes evicting them from land in order to protect it, produced resentment and poor outcomes. Involving stakeholders is not politeness; it is what makes the protection hold.
🧠

Easy way to remember the success factors

People, money, knowing, law, science. Community, funding, education, legislation, research. Then ask the justice question on top: who gains, and who pays?

Worked examples

WE 1

Link value systems to strategy

Explain how an ecocentric and a technocentric perspective would lead to different conservation strategies. (4 marks)

Point 1: the ecocentric view Focuses on the intrinsic value of biodiversity, valuing nature independently of its usefulness to people. Point 2: the strategies it prefers Low-intervention in situ approaches such as large wilderness reserves and national parks, where ecosystems are left largely to themselves. Point 3: the technocentric view Focuses on the economic and societal value of biodiversity and trusts scientific and technological intervention. Point 4: the strategies it prefers Zoos, gene banks, captive breeding programmes and ecotourism — mostly ex situ and heavily managed. Same goal, opposite instincts about how much humans should intervene tie each perspective to in situ or ex situ explicitly; that link is where the marks are
WE 2

Explain factors in success

Explain three factors that influence whether a conservation project succeeds. (3 marks)

Factor 1: community support Engaging local communities and volunteers means the project is supported rather than resisted, as with the partnership between the Snowdonia National Park Authority and local farmers. Factor 2: adequate funding Projects need sustained financial resources; bodies such as the National Lottery Heritage Fund support UK biodiversity work. Factor 3: appropriate legislation Laws such as the Wildlife and Countryside Act 1981 give legal protection to species and habitats, and allow enforcement. Success is mostly social, financial and legal, not only ecological give a named example with each factor; unsupported factors score much lower
WE 3

Apply environmental justice

A marine protected area is proposed in a region where many people fish for a living. Discuss how environmental justice should be considered. (4 marks)

Point 1: the burden Fishing restrictions fall mainly on local fishing communities, so one group carries most of the cost of protection. Point 2: the benefits Benefits such as recovered fish stocks, healthier ecosystems and tourism income may go to a much wider group, or to people elsewhere. Point 3: procedure Stakeholders including fishermen, conservationists and residents should be part of the decision-making, as with the UK’s Marine Conservation Zones. Point 4: the practical case Fair distribution of benefits and burdens also improves compliance, because a community with a stake in the zone will help protect it. Fair outcomes and fair process — and the fair process is what makes it work the compliance argument connects justice to effectiveness, which is a strong way to finish

💡 Exam tips

⚠ Common mistakes

That completes 3.3 Conservation & Regeneration, and with it the whole of Topic 3. The six notes run as one argument: here is why biodiversity is worth keeping, here are the methods, here is how to design a protected area, here is how to rebuild a broken one, here is the global limit we have passed, and here is why people still disagree about all of it. Up next: 4.1 Water Systems.
