Agricultural Land Evaluation Framework

الإطار الوطني لتقييم صلاحية الأراضي الزراعية

A national assessment establishing where agriculture is physically possible, adequately watered, legally permitted and suited to specific crops — assessed hectare by hectare across the Kingdom and delivered as a zoned map of developable land. Select a module below to explore.

Overview
The Method
How the study reaches an answer before any module is opened — the four questions, the depth of what is evaluated, and the descent from national screening to hectare assessment to developable zone.

Land Capability
C1–CN Framework
19 land qualities across 5 groups — soil physical and chemical, water and drainage, topography and erosion, and climate. What the physical ground can support, independent of what is grown on it.

Water Assessment
W-State Framework
15 parameters across source and availability, sustainability, quality, access and delivery, and basin allocation. Assessed separately from the land so irrigated regions are not wrongly disqualified.

Land Rights & Constraints
E-State Screening
Six checks against six separate registers held by different authorities — protection, rangeland, tenure, zoning, competing designations and hazard. An unknown is never read as a permission.

Land Suitability
S1–N2 by Crop
26 diagnostic factors read against each crop’s own tolerances rather than a general threshold. Includes the 63-crop requirement library, 1,268 validated thresholds, and the production-system routing matrix.

Zoning
Hectare to Decision
Grouping assessed hectares into blocks large enough to allocate and develop. Sets boundary rules, the minimum viable area per production system, and the area ledger that reports what is ready and what is held back.
