Appendix C
Crop-wise estimates of rainfed arable landand production potential in Kenya -
assumption set B

The calculation procedures outlined in Chapter 3 have been performed for all crop types, pastures and fuelwood species in all agro-ecological cells of Kenya, altogether more than 90000 land units. As a result, we determine the extent and quality of arable land and production potential of each crop type in all locations. The information is then aggregated to district level, province level and national total. The results are also aggregated over crop types to indicate production potential of crop species, i.e. arable land and production potential for maize rather than nine individual maize types considered in the study.

Three sets of results are presented in this report, in Appendix B to D. The second set, Assumption Set B included here, refers to crop productivity and production potential on all land that is not indicated as forest zone, game park, or belonging to an irrigation scheme. Whenever possible and appropriate, sequential mono-crop combinations of two or three consecutive crop types from a crop species have been constructed to ensure highest possible estimates in sub-humid and humid zones

Six suitability classes have been defined relating average single-crop suitability in a cell to maximum attainable yield. The classes C1 to C5 relate to average attainable yields of >80 %, 60–80%, 40–60%, 20–40%, and 5–20% compared to maximum agro-climatic yields. Note that extents in suitability class C5 are usually not considered among the viable crop options, but have been included here to indicate the scope of production in very marginal areas. A sixth suitability class accounts for areas that are entirely unsuitable or allow only for less than 5 percent of maximum yield. Data for this non suitable class are not explicitly included in the result tables.

Production potential is calculated from land extents in suitability classes C1 to C4 only. Average, minimum and maximum production potential and yields are determined according to the LGP-Pattern and associated probabilities. The columns are labeled AVG, MIN and MAX, respectively. Multiple land use in time, sequential multi-cropping, is indicated by means of a multi-cropping index (MCI).

Each table shows an estimate of arable land by productivity class. The alogrithm used to determine rainfed arable extents in an agro-ecological cell comprises of a two stage procedure. In a first step, the crop or (mono) crop combination that performs best under worst climatic (according to LGP-Pattern) conditions is determined. Then all crops combinations which meet the production stability constraint, i.e. fall within a tolerable neighborhood of the best performing crop, are considered in the final selection. Finally, among all qualifying crops, the crop combination that maximizes the weighted sum of extents in land suitability classes C1 to C4 is selected as describing the cell's arable land potential. Suitable extents of the primary crop type in the chosen crop combination, i.e. the first crop to be grown in the sequential cropping pattern, are recorded in the relevant totals of arable land resources.
