Estimated closeness index and ranking of technologies in semi-arid west and central Africa.

<p>Tech: 1: Early-maturing varieties and hybrids with tolerance to drought; 2: Genetically diverse dual-purpose hybrid parents/cultivars with high and stable yields with disease resistance (downy mildew and blast); 3: Early-maturing, drought-tolerant hybrids which can give stable yields under severe drought conditions; 4: Insect- (aphid, thrips, pod sucking bug, maruca) resistant lines and integrated pest management including biological control; 5: Drought-tolerant varieties and integrated crop management; 6: Drought-tolerant/resistant variety and short-duration (early-maturing) variety; 7: Low P-tolerant varieties and integrated crop management; 8: Biological control of millet head miner and resistant hybrid parents; 9: Striga-resistant varieties and hybrids; 10: Pre and postharvest aflatoxin management practices including Good Agricultural Practices (GAP); 11: Striga-resistant varieties and integrated crop management; 12: Disease-resistant varieties and integrated crop management; 13: Integrated soil fertility management and identifying genotypes for low P tolerance; 14: Stem borer/midge-tolerant cultivars; 15: Cultivars adapted to low soil fertility/and with nutrient-use efficiency; 16: Rosette-resistant variety; 17: Moderately-resistant variety (for short-duration variety) and highly- resistant variety (for medium- and long-duration varieties) to early and late leaf spot; 18: OPVs with host plant resistance to Striga hermonthica; 19: Soil fertility management for P and other nutrients (N, Ca) including chemical/organic fertilizers application; 20: Low P-tolerant/efficient variety. For semi-arid west and central Africa, in the case of the first technology, the normalized index for the benefit-cost ratio criterion is 0.4532; it’s 0.6027 and -0.4722 for the poverty and child malnutrition criteria, respectively. The weighted normalized index for the benefit-cost ratio, poverty and child malnutrition criteria become 0.1763, 0.1664, and -0.1582, respectively. The matrix for the positive-ideal solution is [0.1763; 0.1664; -0.1581] whereas the matrix for the negative -ideal solution is [0.0153; 0.0048; 0.0000]. The Euclidean distances to the positive- and negative-ideal solutions for the first technology are computed as follow: ; The closeness index for the first technology is then computed as: .</p> <p>(DOCX)</p>
