Nutrient losses in eroded soil material from some Kenyan soils

Nutrient loss is one of the factors which causes productivity decline in soils when erosion occurs. This paper gives preliminary results on nutrient losses in eroded soil material in relation to original soil material of some commonly occurring soils in Kenya. Results showed that nutrient losses in eroded soil materials are quite high as indicated by the enrichment ratios of 1.0 for all the nine Kenyan soils studied. Soil conservation measures are recommended

Gender vulnerability to climate variability and household food insecurity

Climate variability presents different challenges for men and for women in their efforts to ensure household food security. However, despite their central role, gender issues have received only cursory attention in adaptation studies. This article looks at causes of gender vulnerability to climate variability and household food insecurity in one sub-Saharan African country: Malawi.

Challenges facing the implementation of differentiation strategy in the operations of the Mumias Sugar Company Limited

Many organizations today are focusing on becoming more competitive, by launching competitive strategies that give them an edge over others. To do this, they need to craft differentiation strategies (Micheal, E. Porter 1985). However, most sugar firms have not been able to formulate strategies required to gain competitive advantage. This calls for a strategic fit of an organization’s core competence levels, technology, leadership styles, markets, culture, people, and environmental influences, which is an emerging paradigm in the study of strategic thinking.

Water and salt movement in salt affected soils in Kimorigo/Kamleza irrigation scheme Taveta, Kenya

Water and salt movement in a recharge- discharge area was studied. Njukini formed the recharge area while the discharge area was located in the Kimorigo/ Kamleza irrigation scheme. Relatioships were drawn between infiltration rates density, moisture. texture, organic KaRt, bulk antecedent and selected physical parameters namely; Vertical Kast, first and third horizons' horizontal KaRt, silt and antecedent moisture correlated positively with infiltration rates. Clay and sand fractions displayed a significant to very highly significant negative correlation with infiltration rates.
