GIS-based Grid Approach

Overview and Objective

Using a grid-based approach in GIS for ecological restoration ensures comprehensive coverage of the target area. By overlaying a 1-hectare grid (100m x 100m), planners can precisely coordinate afforestation alongside soil and moisture conservation (SMC) activities. This method facilitates organized pre-planting surveys, guides planting efforts, and simplifies post-planting monitoring by breaking the site into manageable sections. Ultimately, the grid offers a spatial framework for assigning tasks, tracking progress, and maintaining consistency throughout the project.

The Grid Approach using GIS offers a systematic, scientific, and efficient method for planning ecological restoration. The 1-hectare grid system enhances clarity from planning to implementation and long-term maintenance, ensuring precise plantation efforts and SMC works. It connects spatial data directly with on-ground actions, with each hectare managed and monitored as a distinct unit contributing to broader restoration aims. Implementing this approach helps prevent oversight of any landscape part and allows restoration efforts to be customized to specific site conditions, ultimately boosting project success and sustainability.

Key Benefits of the Grid Approach

  • Uniform Planning Units: Each 1 ha cell is a consistent unit for planning tree planting densities, SMC structures, and maintenance routines.
  • Data Integration: Environmental data (satellite imagery, DEM, land use) should be analyzed per grid cell to tailor interventions to local conditions.
  • Task Allocation: Field teams and community members should be assigned specific grid cells, ensuring full coverage and accountability.
  • Monitoring & Evaluation: The grid provides fixed reference zones for repeated monitoring of survival rates, biodiversity recovery, and SMC effectiveness over time.
