What The Worldwide Expansion Of Protected Areas Means For Shared Stewardship

The numbers are worth sitting with.

According to the World Database on Protected Areas (managed by UNEP-WCMC and IUCN), there are now over 295,000 protected areas worldwide, covering approximately 16.6% of terrestrial and inland water areas and 8.2% of coastal and marine areas. This represents a dramatic expansion from the roughly 3.5% land coverage in 1990.

The rate of growth has accelerated. Between 2010 and 2020, protected areas expanded faster than in any previous decade. And the 2022 Kunming-Montreal agreement — sometimes called the "Paris Agreement for nature" — committed 196 nations to the 30x30 target: 30% of land and ocean protected by 2030.

This expansion is happening across political systems, economic conditions, and cultural contexts. Bhutan has protected over 51% of its land. Seychelles protects about 30% of its marine territory. Brazil's protected areas cover over 29% of its territory (though enforcement is another matter). Germany, Japan, Australia, Costa Rica, Tanzania — the list spans every continent and every income level.

The IUCN classifies protected areas into categories ranging from strict nature reserves (Category Ia, no human activity) to protected landscapes where traditional human use continues (Category V and VI). This range matters because it complicates the simple narrative.

Strict protection — wilderness areas where human access is minimal — covers a relatively small percentage of the total. Most protected areas allow some human activity: sustainable harvesting, traditional livelihoods, recreation, tourism.

This is both a strength and a weakness. The strength is that it makes protection politically feasible. You can protect 30% of the planet if protection includes spaces where people still live and work. The weakness is that "protected" sometimes means very little in practice. A national park with illegal logging, a marine reserve with no enforcement against overfishing, a wildlife corridor bisected by a highway — these exist in large numbers.

The gap between "protected on paper" and "protected in practice" is one of the central challenges of the global conservation movement. Estimates suggest that only about 20-25% of protected areas are effectively managed.

Here is where protected areas connect directly to Law 1.

The establishment of a protected area is an assertion that a piece of land or ocean transcends the interests of whoever currently controls it. This is a unity claim, whether or not anyone uses that language.

When Costa Rica protects 25% of its land, it is saying: these forests are not just Costa Rican. They are part of the planetary life-support system. When the international community designates a UNESCO World Heritage Site, it is saying: this place belongs to humanity. When the Antarctic Treaty System keeps an entire continent free from national sovereignty and resource extraction, it is saying: some things are bigger than nations.

These claims are radical. In a world organized around national sovereignty and property rights, the assertion that land "belongs to everyone" challenges the foundational logic of political and economic power. Every protected area is a small rebellion against the idea that the highest and best use of land is whatever generates the most economic return.

Any honest discussion of protected areas must reckon with the fact that many of them were created by displacing indigenous peoples from their ancestral lands.

Yellowstone, the model for the entire national park movement, was established after the forced removal of the Shoshone, Crow, Blackfeet, Bannock, and other tribes who had lived in the area for thousands of years. The "wilderness" that American conservationists sought to preserve was not wilderness at all — it was a landscape shaped by millennia of indigenous management, including controlled burns, selective harvesting, and wildlife management.

This pattern — expelling indigenous communities in the name of conservation — has been replicated across Africa, Asia, and Latin America. An estimated 20 million people have been displaced by conservation projects worldwide. The term "fortress conservation" describes the model: protect the land by keeping people out.

The irony is brutal. The people with the longest track record of sustainable land management were removed so that the people with the worst track record could "protect" the land.

The good news: this is changing. Indigenous and community-conserved territories (ICCAs) are increasingly recognized as legitimate protected areas. Research consistently shows that indigenous-managed lands have biodiversity outcomes equal to or better than government-managed protected areas. The 30x30 framework explicitly references the role of indigenous peoples and local communities. Nations like Australia, Canada, and Colombia are creating co-managed protected areas that share governance between indigenous communities and national authorities.

This shift is itself a unity practice. It requires colonial-era conservation institutions to admit they got it wrong and share power with the people they displaced. That is reconciliation in real time.

Some of the most powerful examples of shared stewardship are transboundary protected areas — parks that span national borders.

The Kavango-Zambezi Transfrontier Conservation Area covers 520,000 square kilometers across Angola, Botswana, Namibia, Zambia, and Zimbabwe. It is one of the largest conservation areas on Earth, and it requires five nations with different political systems, economic conditions, and historical tensions to coordinate wildlife management, anti-poaching efforts, and community development.

The European Green Belt follows the line of the former Iron Curtain from the Barents Sea to the Black Sea. The no-man's-land between NATO and Warsaw Pact nations, abandoned by humans during the Cold War, became an unintentional wildlife corridor. After the fall of the Berlin Wall, conservation organizations worked to preserve this corridor — turning a symbol of division into a symbol of ecological connection.

Peace Parks — protected areas established between former adversaries — exist between Ecuador and Peru, between North and South Korea (the DMZ), and between several countries in the Great Lakes region of Africa. The logic is explicit: shared stewardship of nature can build trust between nations that have no other basis for cooperation.

The expansion of marine protected areas represents a particularly interesting unity challenge because the ocean is fundamentally shared. Fish don't respect national boundaries. Currents carry nutrients, pollutants, and larvae across entire ocean basins. Protecting a patch of ocean in one country while the adjacent country overfishes is futile.

This is why the 2023 High Seas Treaty (the BBNJ Agreement) was significant. For the first time, it created a framework for establishing protected areas in the high seas — the roughly 64% of the ocean that lies beyond any nation's jurisdiction. These waters belong to no one and everyone. Protecting them requires a level of international cooperation that has no precedent.

Early proposals include protecting the Sargasso Sea (a critical habitat in the mid-Atlantic that no nation borders), regions around deep-sea hydrothermal vents, and migration corridors for whales and tuna.

Can we actually protect 30% of the planet by 2030?

The honest answer is: probably not at the quality level needed, but the attempt will still move the needle significantly.

The biggest obstacles are not ecological. They are political and economic. Protecting 30% of land means restricting development on land that someone wants to use. Protecting 30% of ocean means restricting fishing in waters that fishing industries depend on. Every square kilometer of protection represents a negotiation between present economic interests and future ecological necessity.

The unity framework helps here. If you see protected areas as "someone else's sacrifice," you resist them. If you see them as "our shared investment in a livable planet," the calculus changes. The framing determines the politics.

Mapping. Look up the protected areas within 100 kilometers of where you live (protectedplanet.net is a good resource). Visit one. Sit in it for an hour without a phone. Notice what it feels like to be in a place that a society decided to leave alone.

Historical. Research who lived on the land that is now your nearest national park or nature reserve before it was protected. Were indigenous or local communities displaced? Has any reconciliation process occurred?

Systems. Identify one resource conflict in your region — developers vs. conservation, fishing vs. marine reserves, logging vs. forest protection. Map the stakeholders and their interests. Where is the overlap? What would stewardship look like that serves all parties?

Philosophical. Write for ten minutes on this question: If the land could speak, what would it say about how we've treated it? Not as an environmental guilt exercise. As a genuine attempt to shift perspective from owner to steward.
