The Food and Agriculture Organization (FAO) of the United Nations released the latest State of the World’s Forests report on July 22, 2024. It presents a mixed picture of global forestry: encouraging signs of reduced deforestation, tempered by emerging threats from climate change-driven wildfires, pests, and sea-level rise.

Current Status of Global Forests

Forests remain one of Earth’s most crucial ecosystems, covering 31% of global land area (~4.1 billion hectares in 2020). They provide habitat, regulate climate, support livelihoods, and maintain biodiversity.

Global Forest Area Distribution:

• Top 5 forest-rich countries (54% of global forest area):
  1. Russian Federation
  2. Brazil
  3. Canada
  4. USA
  5. China
• Other significant contributors include: India, Indonesia, Australia, Peru, Democratic Republic of Congo.

From 1990–2020, approximately 420 million hectares of forests were converted to other land uses. However, the rate of deforestation has significantly slowed over recent decades — a clear indication of global conservation efforts and policy interventions.

Declining Deforestation Rates: A Positive Trend

Deforestation rates have declined considerably:

• 1990–2002: 15.8 million ha lost per year.
• 2015–2020: reduced to 10.2 million ha per year.
• Net forest loss (2010–2020): 4.7 million ha/year, compared to 7.8 mn ha/year (1990–2000).

Regional Trends:

• Africa: 4.41 mn ha/year lost.
• South America: 2.95 mn ha/year.
• Asia: 2.24 mn ha/year.

Success Stories:

• Indonesia: 8.4% decline in deforestation (2021–22 vs. 2020–21), lowest since 1990.
• Brazil: 50% drop in Amazon deforestation in 2023 compared to 2022.
• Africa: Decreasing rates across subregions.

Countries Achieving Forest Gains

10 countries recorded annual forest area gains in 2020, including: China, India, Australia, USA, Vietnam, Chile, Turkey, France, Italy, Romania.

These gains reflect national afforestation and reforestation programs, improved forest governance, and community-based conservation.

Mangroves: Resilience and Risks

• Global mangrove area: 14.8 mn ha, with 44% in South & Southeast Asia.
• Mangrove loss decreased by 23% over the last two decades.
• Gains have also slightly declined, with Asia showing highest rates of loss and gain, mainly due to:
  • Aquaculture
  • Palm oil plantations
  • Rice cultivation
  • Natural processes

However, sea-level rise and extreme weather events linked to climate change are threatening mangrove ecosystems and increasing the vulnerability of coastal communities.

Escalating Threats: Wildfires and Pests

Wildfires:

• Global fire-affected land: ~340–370 mn ha/year.
• 2023 alone: 383 mn ha burned, emitting 6,687 megatons of CO₂ — more than double the EU’s emissions from fossil fuels.
• Canada: ~14.6 mn ha burned in 2023, five times the 20-year average.

Wildfires are intensifying in frequency, scale, and emissions due to extended droughts, higher temperatures, and fuel build-up.

Pests and Diseases:

• Significant damage to pine forests in China, Japan, Republic of Korea due to pine wood nematode.
• Korea lost ~12 million pines between 1988–2022.
• USA estimates show >20% host tree basal area loss in ~25 mn ha by 2027.

These threats compound the ecological and economic costs of forest degradation, impacting timber, ecosystem services, and community livelihoods.

Key Implications

Positive outcomes:

• Progress in reducing deforestation.
• Successful afforestation and restoration in many regions.
• Mangroves showing resilience.

Emerging concerns:

• Wildfires becoming more destructive.
• Pests and diseases under-monitored.
• Climate change exacerbating forest vulnerability.
• Mangrove gains lag behind losses in certain areas.

The report highlights the urgent need for:

• Strengthened monitoring of degradation and pest outbreaks.
• Climate-resilient forestry practices.
• Greater international cooperation to sustain gains and address new threats.

The State of the World’s Forests 2024 demonstrates that concerted global efforts can curb deforestation and restore ecosystems. Yet, rising threats from climate change — particularly wildfires, pests, and sea-level rise — pose severe challenges. To secure the world’s forests for future generations, adaptive management, robust policy measures, and local community engagement are critical.
