### African forest elephants and their conservation status
- Historically about 1.1 million African forest elephants once roamed the central African rainforests.
- Deforestation and poaching have diminished their population to less than one-tenth their former number.
- Forest elephants likely face extinction unless action is taken.
- African forest elephants are little known outside central Africa; there is virtually no ecotourism in the central African rainforests for geographic and political reasons.

### Ecological role: elephants as environmental engineers
- As they forage and move through rainforests, elephants thin out young trees by stepping on some and consuming others, dramatically reducing vegetation density.
- The remaining unbroken trees gain much better access to water and light, enabling them to grow taller and larger.
- Wherever forest elephants roam, they promote the growth of larger, taller trees, enhancing the forest’s carbon storage capacity.

### Quantitative impacts on carbon capture
- Biologists estimate that a recovery of African forest elephants to former population size and range would increase carbon capture by 13 metric tons (1 metric ton = 1,000 kg) per hectare (10,000 square meters).
- The former range of African forest elephants was 2.2 million square kilometers.
- Each square kilometer comprises 100 hectares.
- Forest elephants are now at about 9 percent of their pre-poaching population.
- Carbon capture from a recovery of these elephants could be equivalent to more than 6,000 metric tons of carbon dioxide per square kilometer.
- That amount of carbon dioxide captured equals the carbon captured by over a quarter of a million trees, or 14 times what is captured by trees in New York City’s Central Park.
- Using the average market price of a metric ton of carbon dioxide—just under $25 in 2019—the total present value of the carbon-capture services of African forest elephants is over $150 billion.
- Dividing the total value of the service by the current population implies each elephant is responsible for service worth more than $1.75 million.
- The ivory of an elephant killed by poachers fetches only about $40,000.

### Valuation framework and investment incentives
- The authors developed a framework for natural resource valuation that directly addresses the collective action problem in environmental protection.
- Key rationale:
  - Market-value measurements of services (recreation, tourism, carbon sequestration) allow dollar-to-dollar cost-benefit comparisons analogous to other assets.
  - Present-monetary-value estimates of ecosystem services can motivate investment when they exceed the cost of preservation.
  - Monetary valuations make the benefits concrete and can inspire behavioral responses that lead to investment and ownership.
- Valuations that are actionable are based on believable stories about how assets generate cash or income and credible projections summarized in present monetary value.

### Policy instruments, institutional arrangements, and economic opportunities
- Valuing natural resources and establishing a legal framework that appoints stewards and defines rights and obligations enables win-win opportunities among government, the private sector, local communities, and global partners.
- Economic benefits from natural resources can be claimed and distributed to create incentives for public-private partnerships supported by nongovernmental organizations and global institutions.
- Example instrument: debt-for-nature swaps (United Nations Development Programme Financing Solutions for Sustainable Development initiative)
  - Under such contracts, lenders agree to reduce a developing economy’s debt or debt payments in exchange for a commitment to protect specific natural resources.
  - Many countries that host forest elephants are highly indebted and could benefit from debt-for-nature swaps.
  - The amount of debt relief is determined by the value of the elephants’ services, using market prices.
  - Savings from debt relief would be devoted to elephant conservation and could facilitate public-private partnerships to build markets (tourism, insurance) around investing in and protecting elephants.
- Nongovernmental organizations and international financial institutions could provide capacity development for public-private partnerships and insurance markets centered around natural resources.
- Valuing nature for its benefits can support a virtuous cycle directing investment and enterprise toward regenerative and sustainable outcomes.

### Broader context and policy implications
- Population context noted in the article:
  - It took more than 50,000 years for world population to reach 1 billion people.
  - Since 1960, successive billions have been added every one to two decades.
  - World population was 3 billion in 1960; it reached 6 billion around 2000.
  - The United Nations projects the world population will surpass 9 billion by 2037.
  - The population growth rate has been slowing from peak annual rates in excess of 2 percent in the late 1960s, to about 1 percent currently, to half that by 2050.
- The COVID-19 pandemic demonstrates that destruction of nature can have macrocritical global impacts, underscoring the need for a course correction.
- Vibrant, intact ecosystems (including healthy populations of forest elephants, great whales, mangroves, and sea grass) illustrate how valuing and investing in nature can:
  - Generate a more sustainable blue-green economy,
  - Help mitigate climate change,
  - Realign economies toward inclusive and nature-friendly economic growth.
