Design protected nature as a connected network that wildlife can travel through, not as isolated dots
Steps to make it happen
- Scientists study the routes that animals and plants take as the seasons change and the weather gets hotter.
- People draw a map of the "pathways" that join protected places in forests and seas.
- Farms and fishing grounds on these pathways stay in use, with small changes such as keeping hedgerows.
- Before building a road or a dam, builders check whether it would cut a pathway.
- When a pathway must be cut, builders make a bridge for animals or a fish ladder instead.
- Neighboring countries make a promise to protect pathways that cross their borders together.
- Local people and fishers who help protect the pathways get paid.
- It becomes normal for living things to move freely through nature.

The proposal in detail
This proposal makes one question a central test in conservation rules: not only how large protected areas are or how many there are, but whether they are connected to each other for wildlife. It covers forests, grasslands, rivers, and wetlands on land, as well as sea routes used by migratory fish, whales, and sea turtles, and the resting stops where migratory birds take a break. Countries and regions use studies of animal movement to make a "map of nature's connections" and to name the pathways that must be protected, which are called corridors. A corridor does not have to be a closed-off reserve. Even farmland, private land, or fishing grounds can be named as corridors, with gentle conditions on how they are used, such as keeping riverside woods and hedgerows or holding back fishing in certain seasons. Companies that plan roads, dams, railways, long fences, or large developments must assess beforehand whether the plan would cut a corridor. If it would, they are required to build a substitute, such as a bridge for animals to cross or a fish ladder, or to choose a different route. For corridors that cross borders, the countries involved make joint management agreements, and an international framework supports them with research and funding. Landowners, Indigenous peoples, and local fishers take part in the talks from the stage when a designation is being considered, and they receive compensation or payments according to how much they cooperate. As an exception, the proposal also allows a decision not to connect places where there is a large risk that invasive species or livestock diseases would spread along the pathway.
BenefitsProtected nature stays alive and handles climate change better
When protected areas are connected, animal groups can travel back and forth and mix their bloodlines. If one group is weakened by disease, wildfire, or drought, individuals from other places can move in and help it recover more easily. Because living things can move their homes as the climate changes, the chance of avoiding extinction rises even as the world warms. Even in crowded regions where it is hard to set aside new reserves, results can come from small changes to how existing land is used, such as keeping riverside woods and hedgerows or adjusting fishing seasons, so big gains can be expected for the cost. When a river running through a forest is reconnected, fish can travel between upstream and the sea and carry nutrients, which also supports fishing, so protecting forests and protecting seas help each other. Joint management across borders is a realistic way to protect creatures that no one country can protect, such as migratory birds and fish, and it can also build cooperation and trust between neighboring countries. If the important pathways are known before development begins, companies can adjust their plans early, and fewer projects will be stopped later by protests or lawsuits.
DrawbacksIt may restrict the freedom of people on the land and spread the burden unevenly
What opponents worry about most is that naming a pathway puts outside limits on how the people who live and work there can use their land. Not being able to expand a field, limits on grazing livestock, and shorter fishing seasons are likely to fall hardest on poor farming and fishing villages, and there is no guarantee that the promised compensation will keep being paid. In the past, people were driven off their land in the name of nature protection, and distrust of such systems runs deep. If roads and dams must go through a prior assessment and have substitute pathways built, construction costs rise and finishing is delayed, and critics say this holds back the development of regions that still lack enough electricity and transportation. Joint management across borders means having to consult other countries about how to use one's own land, which will be hard to accept for those who value national sovereignty. Also, pathways can let invasive species, diseases, and wild animals that damage crops through too, so some areas will see more conflict between people and wildlife. Finding out which places are the important pathways takes money and time, and there is a risk that designations will go ahead while the science is still uncertain.
Learn the background
Until now, nature conservation has mostly meant drawing a line around a specific place and protecting it, as with national parks and marine protected areas. The total area enclosed has grown around the world, but much of it is surrounded by roads, farms, and cities, and it is cut off like islands in the sea. Yet living things do not stay in one place. They look for food, give birth, and travel over wide areas as the seasons change. A small, shut-in group can only have young with close relatives, becomes weak against disease and disasters, and tends to disappear over time. On top of that, as climate change raises temperatures, many creatures try to move up to cooler mountains or to colder regions, but without pathways they cannot move. In the sea too, the routes of fish and whales cross both the waters each country manages and the high seas, so no single country can protect them alone. Because aiming only for a certain amount of protected area cannot stop wildlife from continuing to decline in places that were supposedly protected, there is a growing need to make connection itself a pillar of the system.
