Farm input marketing in western Kenya : Challenges and opportunities

Widespread and increasing rural poverty in sub-Saharan Africa has been of great concern to development community. Low use of inputs by farmers, due to market constraints that reduce profitability of input use, is one of the factors responsible for the gap between potential and actual yields. Using questionnaire, this study interviewed 130 agro-input dealers in Kenya to analyze challenges and opportunities in input delivery. Results indicate that there has been a steady annual growth (2 – 22%, with mean of 16%) in their number. Di-ammonium phosphate fertilizer (stocked by 92% respondents) was most commonly stocked, followed by Calcium Ammonium Nitrate fertilizer (84%), Urea (78%), and NPK (40%). Other services provided by agro-dealers are input information (75% respondents), credit (13%), bulk breaking (8%), and spraying (4%). Inputs selling price increased with distance to markets; long distances to market disconnect villages from input supply chain. High transport cost (53%), low demand (30%), lack of market information (21%), lack of storage facilities (13%), and limited business knowledge (12%) were the most important constraints faced by agro-dealers. Policies and institutional frameworks suggested by dealers to streamline input trade were associated. The study concludes with suggestions on how to enhance efficiency of agro-dealers in input delivery

Assessment of professional training programmes in international agricultural research institutions: The case of ICRAF

The following survey was undertaken in 2005 to assess the effectiveness of professional training activities in international agricultural research organizations that were undertaken between 1999 and 2002 at ICRAF (International Centre for Research in Agroforestry), now World Agroforestry Centre, Nairobi. Trainees were randomly selected from various professional fields in the agroforestry domain. Survey questionnaires and telephone interviews were adopted. Descriptive statistics, logit regression, cross-tabulations and bi-plot analysis were used to analyze the data. The Kirkpatrick's training evaluation theory provided the methodological framework for the study. Male participants were more educated and had longer average professional experience than females. Trainees had good recollection and learning of various aspects of the training. There was high potential for skill transfer and practical implementation of training skills among all trainees, but lack of resources was a major limitation. Female workers faced more constraints during workplace implementation of skills than male workers. The study has practical implications for current and future design and evaluation of training in agricultural domains. The work also contributes to knowledge building in training evaluation within agricultural institutions in Africa, which is poorly documented or lacking in certain specific settings. The paper is original because scientific evaluation of training activities in agricultural practice in Africa is rarely or poorly documented, thus adding value to agricultural research

Rainfall variability, drought characterization, and efficacy of rainfall data reconstruction: case of eastern Kenya

This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Analyses of rainfall variability utilized rainfall anomaly index, coefficients of variance, and probability analyses. Spline, Kriging, and inverse distance weighting interpolation techniques were assessed using daily rainfall data and digital elevation model using ArcGIS. Validation of these interpolation methods was evaluated by comparing the modelled/generated rainfall values and the observed daily rainfall data using root mean square errors and mean absolute errors statistics. Results showed 90% chance of below cropping threshold rainfall (500 mm) exceeding 258.1 mm during short rains in Embu for one year return period. Rainfall variability was found to be high in seasonal amounts (CV = 0.56, 0.47, and 0.59) and in number of rainy days (CV = 0.88, 0.49, and 0.53) in Machang’a, Kiritiri, and Kindaruma, respectively. Monthly rainfall variability was found to be equally high during April and November (CV = 0.48, 0.49, and 0.76) with high probabilities (0.67) of droughts exceeding 15 days in Machang’a and Kindaruma. Dry-spell probabilities within growing months were high, (91%, 93%, 81%, and 60%) in Kiambere, Kindaruma, Machang’a, and Embu, respectively. Kriging interpolation method emerged as the most appropriate geostatistical interpolation technique suitable for spatial rainfall maps generation for the study region

Smallholders' coping strategies in response to climate variability in semi-arid agro-ecozones of Upper Eastern Kenya

Rainfed agriculture dominates food production systems in arid and semi-arid agro-ecozones. Water is a key limiting factor to crop growth in the small-scale farming systems of the Sub-Saharan Africa (SSA) region. Climate adaptation is a fundamental and necessary response to the threat posed by the current and future climatic changes in semi-arid farming systems of the SSA region. This study was implemented to identify the socioeconomic drivers and determinants of adaptation to rainfall variability at the farm level in contrasting agro-ecological zones of Kenya. Two hundred and seventy (270) farmers were selected. The survey was implemented in Mbeere South, Meru South, and Maara Sub-Counties in Kenya to determine farmers' perceptions of climate variation during the decade that preceded the survey and climate adaptation strategies that farmers implemented. The most common climate adaptation strategies included the use of terraces (89%), early maturity crop varieties (82%), and intercropping (79%). In comparison, the least common strategies included water-harvesting strategies (29%), trenches (35%), and staggering planting dates (46%). Farmers in low potential agro-ecological zones recorded lower education levels, less secure land tenure systems, and poor access to training, extension, and credit facilities necessary for successful climatic adaptation strategies. The study findings indicated that farmers in low potential zones, including Mbeere South Sub-County, faced more risks due to the nature of climatic variation in this agro-ecozone. Farm socioeconomic characteristics were important factors that influenced farmer adaptation, including gender and age differentials, education attainments and agricultural training, farm labor availability, household food security status, and preceding annual occurrences of crop failure. There is a need to develop holistic approaches that incorporate scientific findings from the researchers and the local household-based strategies that can enhance risk assessment and management, coping and adaption strategies, and decision-making by multiple stakeholders

Enhancing sustainable agri-food systems using multi-nutrient fertilizers in Kenyan smallholder farming systems

Persistent food insecurity in the global south has triggered calls for sustainable development worldwide. Moreover, more than a quarter of the world's population suffers from micronutrient deficiencies or hidden hunger. The population bulge, declining soil fertility and inadequate/inappropriate use of farm inputs in Sub-Saharan Africa place it in a precarious position. Multi-nutrient fertilizer blends have been mooted as a key innovation in closing yield gaps and boosting food and nutrition security. This study assessed the extent of multi-nutrient fertilizer blends utilization and yield response across agroecological zones and their on-farm profitability under Kenyan smallholder farmer conditions. We collected data through a detailed household survey conducted in eight counties in Kenya representative of high, medium, and low productivity zones using a sample of 1094 smallholder farmers. Multi-nutrient fertilizers increased maize yields significantly (P < 0.05), eliciting a 400% yield increase compared to the control and 108% greater maize yield than conventional fertilizers in the high potential zone. Conversely, at 3.7 t/ha conventional fertilizers elicited a significant (P < 0.05) yield response in Irish potatoes in the high potential areas. Multi-nutrient fertilizers increased on-farm profitability of crops, specifically for potato production systems where a benefit: cost ratio (BCR) of more than 2 was observed. Farmers may break even when they use multi-nutrient fertilizers on maize particularly in the low potential areas. Therefore, there is considerable potential for multi-nutrient fertilizers to increase crop productivity while being economically viable across agroecological zones and cropping systems. However, the uptake of multi-nutrient fertilizers among farmers is quite low across the country, except for small pockets where limited interventions have been carried out. This calls for sustained efforts to scale multi-nutrient fertilizers with a focus on clear messaging that stresses the need to apply appropriate rates of various nutrients including the secondary nutrients and micro-nutrients
