Understanding global land use intensity is crucial for sustainable agriculture. This study reviews mapping approaches and datasets, highlighting challenges and future research needs for intensified food production.
Area of Science:
- Agricultural Science
- Environmental Science
- Geospatial Analysis
Background:
- Sustainable intensification of land-based production is vital for future food security.
- Current understanding of global land use intensity patterns is limited due to complexity and data gaps.
- Assessing land use intensity requires multidimensional approaches across diverse geographic scales.
Approach:
- This research reviews current methodologies for mapping land use intensity.
- It provides a comprehensive overview of existing global-scale datasets relevant to land use intensity.
- The study identifies challenges and opportunities in mapping land use intensity for various systems.
Key Points:
- Land use intensity is a complex, multidimensional concept.
- Global datasets for assessing land use intensity are scarce and varied.
- Mapping land use intensity is essential for sustainable agricultural intensification.
Conclusions:
- Improved mapping of land use intensity is critical for sustainable intensification of agricultural, grazing, and forestry systems.
- Addressing data limitations and methodological challenges is key for future research.
- This work identifies critical areas for advancing global land use intensity assessments.
