A long-term forecast analysis on worldwide land uses

Area of Science:

• Environmental Science
• Agricultural Science
• Global Land Use Analysis

Background:

• Increasing global land cultivation for food production coincides with unprecedented deforestation rates.
• Future land use trends are crucial for policymakers, researchers, and the public.

Purpose of the Study:

• To forecast global land use changes over the next 25 years.
• To provide a detailed outlook on future land use patterns worldwide.

Main Methods:

• Utilized historical land use data since 1961 to establish trends.
• Employed univariate linear regressions to fit land area trajectories.
• Generated forecasts for land use up to the year 2030.

Main Results:

• Agricultural, arable, and permanent pasture land areas are projected to increase by 6.6%, 7.2%, and 6.3% respectively by 2030.
• Forests and woodlands are expected to decrease by 2.4%, while other land areas will decline by 6.4%.
• Agricultural land expansion is concentrated in developing countries, driven by population growth and food security needs.

Conclusions:

• Agricultural land expansion in developing countries significantly contributes to global increases, exacerbating climate change and environmental degradation.
• Addressing population growth and promoting sustainable agriculture are critical for mitigating agricultural land expansion.
• Sustainable agriculture practices are essential for meeting food demands with minimal environmental impact.
