Table 2.1 List of visual classes determined for the Nyando study region, Kenya

From: Targeting Landscapes to Identify Mitigation Options in Smallholder Agriculture

  Class Delimitation criteria Mitigation opportunities
A Cultivated land dominated by cash crops Presence of an agricultural matrix, i.e., extensive (>70 % of the area) and connected (few identifiable large patches) cover. Most plots (>75 %) are comparatively large and of similar size (~1 ha), regular-shaped (rectangular), and have a heterogeneous color and brightness. Heterogeneity in this class originates from plough or crop lines, pointing to a crop cover. Presence of infrastructure (e.g., houses, storage places, etc.). No degradation signs (e.g., surface salt accumulation, lack of vegetation, gullies) Agroforestry, fertilizer management
B Natural vegetation Presence of a matrix of any original vegetation type (forests, shrublands, savannahs). Trees or large shrubs are clearly distinguishable by their round shape or shadows in the images Halting land and tree cover degradation
C Mixed natural vegetation and agricultural land No single cover type reaches 70 % of the area, and patches of crop, pasture, and natural vegetation are intermingled Agroforestry, livestock management
D Cultivated land dominated by subsistence crops Same as A, but most plots are smaller, of variable area and shape (rounded, elongated, irregular). In this class, heterogeneity comes in addition from patches of herbaceous or shrubby vegetation within plots (a sign of land abandonment), and surface degradation Fertilizer and manure management, agroforestry
E Agricultural land dominated by grazing land Same as A, but most plots are comparatively larger, have irregular shape (no bilateral symmetry), and lack of plough or crop lines. Frequent isolated trees or shrubs inside plots. Signs of infrastructure are less common than in A Livestock management, manure management, agroforestry
F Mixed cultivated land Both elements of A and D are found intermingled within small areas Agroforestry, fertilizer, and manure management
