Global Land and Biodiversity Data: Mapping Ecosystem Changes

This dataset examines the relationship between land use changes and biodiversity trends over time, covering the years 2005, 2010, 2021, and 2024. The primary source of raw data is the UN Data for Environment: Land Estimates, last updated in November 2024. It helps researchers, policymakers, and environmentalists analyze how human activities impact ecosystems and biodiversity conservation efforts.

Research Hypothesis:
We hypothesize that increased agricultural land use and deforestation correlate with a decline in biodiversity protection. Specifically:

Higher arable land percentages lead to lower forest cover and fewer protected biodiversity sites.
Countries with stronger conservation policies will show higher biodiversity protection values despite land use changes.
Regional differences will depend on policy interventions, climate conditions, and economic development.

Key Findings:
Deforestation is increasing in several regions due to agricultural expansion.
Biodiversity protection efforts are uneven, with some countries improving and others stagnating.
Some nations successfully balance agriculture and conservation, while others struggle with sustainability.

Dataset Structure
The dataset has two key components:

🌍 Land Use Data (final_filtered_countries_cleaned.csv)
Country & Year – Tracks changes over time
Arable Land % – Land used for crops
Forests % – Land covered by forests
Crops % – Land for permanent crops
Use – Helps monitor deforestation and land degradation trends
🦋 Biodiversity Data (bio_countries_cleaned.csv)
Country & Year – Tracks biodiversity indicators
Series – Description of the indicator measured
Value – % of key biodiversity sites under protection
Use – Helps track conservation and biodiversity protection
How to Interpret the Data
High arable land percentages & declining forest cover → Rapid agricultural expansion.
Increasing protected biodiversity sites → Effective conservation policies.
Year-to-year comparisons → Identify trends and policy effectiveness.
Cross-country comparisons → Understand sustainable land-use practices.
Applications & Importance
✔ Tracking Environmental Changes – Helps monitor deforestation and biodiversity loss.
✔ Policy Decision-Making – Supports sustainable land-use planning.
✔ Sustainable Development Goals (SDG 15) – Provides insights into forest and biodiversity conservation.
✔ Scientific Research & Climate Studies – Helps study climate change impacts.
✔ Educational Use – Real-world data for students and educators.

This dataset is a valuable resource for understanding land use, conservation policies, and biodiversity protection worldwide.
