This paper presents the marketing performance and efficiency of evaporative-preservation cooling

system for fresh tomato as an update of the performance evaluation of the evaporative cooling system

developed at the Federal University of Technology Akure, Nigeria. A total of one hundred and five (105)

fresh tomato marketers were sampled. Marketing margin analysis was performed to determine the

performance of the preserved tomato vegetable during dry season based on their mode of preservation.

Shepherd’s efficiency formula result analysis shows that fresh tomato market was efficient with

average marketing efficiency of 17.65%. The two-independent samples t-test results (t-value = 74.014)

further reveal that profit margin for users of evaporative cooling system is significantly different from

users of traditional mode of preservation, at 5% level of significance. However, disaggregated

wholesaler’s profit margin of N6,261.6 per month for users of traditional preservation method implies

that they are not efficient compared with users of evaporative cooling system averaging N12,381.4 per

month. Given the wide tropical variability in temperatures and relative humidity, evaporative cooling

system is of economic importance towards commodity marketing development in Ondo State, Nigeria.

The study analysed the determinants of farmers’ decision capacity on climate risks adaptation in Ekiti State, Nigeria. Multinomial logit model was fitted to data collected from a cross-sectional data obtained from selected food crop farmers. Primary data were collected using a well-structured questionnaire administered on eighty farmers who were randomly selected from the two agro-ecological zones of the State. A multi-stage sampling technique was used to select the respondents from the tropical forest and guinea savanna zones in the study area. The results from the perception mean scores indicate that the magnitudes of drought, heavy, storm, fire incidence, heavy rainfall, thunderstorm, and soil erosion were perceived as moderate, while loss of soil moisture, flood, incidence of pests and diseases, desertification and loss of forest resources were perceived as high climate risks. Increase or reduce the size of their cropland, active farming activities, protective measures and some household livelihood adaptations were various adaptation strategies adopted to cope with climatic stresses associated with seasonal fluctuations of weather factors and/or  extreme events. While, access to basic infrastructure and productive assets will enhance farmers’ adaptive capacity to adjust, inadequate availability of storage facilities will deter their capacities to adjust to risks from extreme climate events. The chi-square value of 61.10 associated with the log likelihood ratio of 207.60 was significant (p<0.05) in the multinomial logit result which indicate a strong explanatory power of the model.  The significant factors that affect farmers’ adaptive capacity to climate risks were household head level of education, farming experience, extension services, and access to credit opportunities were statistically significant (p<0.05) and exert positive influence on choice of adaptation options to cope with stresses from impacts of climate risks.
