Authors:Amira Abdelhamid, Houcine Jeder, Ahmed Salah Pages: 1 - 8 Abstract: Climate change should have impacts on Tunisian arid regions oasis households are likely to bear the most significant negative impacts, the case of the oasis of "Metouia" in the governorate of "Gabes". This research is based on an econometric analysis through cross-sectional probit models involving 50 oasis households. The binary probit models showed that certain factors contribute significantly to the adaptation strategies identified, such as: the age of the agricultural household head, agriculture as a main activity, the agricultural production system adopted the mode of ownership of agricultural land, extension for farmers. All actions aimed at improving the resilience of Tunisian oasis agricultural households to climate change focus mainly on the strategies adopted by farmers in terms of water management, the technical choices and the production systems adopted combined with the experience and local know-how.

Multi-stage sampling technique was used select 60 respondents. Data collected were analyzed using descriptive statistics and the ordinary least square regression technique. Results showed that the area was dominated by female farmers 56.7%, and are married 66.7%. Most of the farming lands used was inherited, with more of hired laborers 76.7% used due to rural-urban drift. Results also showed that over 70% of the people migrated from rural to urban communities. Result further showed that age, gender, educational status, income level and poverty index were important and significant factors affecting population dynamics (expressed as index of rural–urban migration). The study recommended the crop farmers to join cooperative societies to raise funds to support large-scale production while the government is to provide basic rural infrastructures to checkmate rural-urban drift in the area.

Authors:Akele EO, Akinyosoye FA, Oyetayo VO Pages: 17 - 21 Abstract: The aim is to study the microorganisms involved in fermentation, their occurrence and the organoleptic properties of fermented watermelon (Citrullus lanatus) seeds. The watermelon seeds were dehulled, sorted, washed and boiled for 4 hours and fermented naturally for nine days. Microorganisms isolated from the fermenting watermelon seeds were Bacillus sp, Lactococcus sp, Pediococcus sp, Streptococcus sp, Micrococcus sp and Alcaligenes ps for bacterial, while the fungi obtained were Mucor sp, Rhizopus sp, Fusarium sp, Candida sp and Saccharomyces sp. The bacterial count increased from 4 x101 cfu/mL to 1.21 x 1010 cfu/mL while fungal count also increased from 8 x 101sfu/mL to 1.2 x 109sfu/mL during the period of fermentation. The pH and temperature increased from 6.3 to 8.7 and 29oC to 40oC respectively. The total titratable acidity decreased from 0.176% to 0.027%. The mean sensory characteristics value of fermented sample as scored by the panelist shows that the texture of the fermenting sample become softer as fermentation progressed. The aroma became more pungent with a strong ammonia odour responsible for the characteristic flavour and a darker colour of product. The overall acceptability of fermented sample was adjudged like very much while the sample bought from the market was adjudged like moderately.

Authors:Ouertani Emna, Dhraief Mohamed Zied Pages: 22 - 31 Abstract: The aim of this paper is to investigate the extent to which factors determining the purchase of olive oil within Tunisian consumers also determine their choice of its place of purchase. Based on an exploratory survey carried out with Tunisian household heads, an exploratory factor analysis was conducted to determine the principal dimensions of quality attributes and indicators. To evaluate factor determining olive oil purchase decision and its place of purchase choice, a binomial and a multinomial logistic regressions are respectively used. Consumer sensibility to brand and price have a negative impact on buying decision and on the choice of mills, relatives, and store retail, as suppliers of olive oil. Originating from a production area encourage consumers to buy olive oil from friends and relatives. Tunisian olive oil industry is therefore able to adopt product and distribution policies based on consumer expectations, to improve local market consumption.

Authors:Mohammad Ali, Kira M Villa Pages: 32 - 38 Abstract: The accurate conversion of household-level food availability into individual-level nutrient availability depends on which adult-equivalent scale is employed. The purpose of this paper is to come up with a set of adult-equivalent scales based on the specific daily intake requirement for macro- and micronutrients. Using t-tests on household-level data from Nepal, we also attempt to find whether on average there are differences between the individual-level nutrient availability estimates when they are calculated through nutrient-specific versus calorie-based, per capita, or Organization for Economic Cooperation and Development (OECD) adult-equivalent scales. The results suggest that on average there are significant differences between the individual-level nutrient availability estimates depending on which adult-equivalent scale is used. Finally, we find that nutrient-income elasticities calculated through different adult-equivalent scales are statistically different from each other. Thus, the nutrient-specific adult-equivalent scales derived in this paper have the potential to reduce measurement error in future studies.

Influence of packaging material and rates of potassium permanganate (KMnO4) on postharvest ripening of garden egg was evaluated to access the interactive effect of KMnO4 and packaging material in delaying ripening. Two packaging materials; polythene and jute bags, KMnO4 at 0g, 3g, 6g and 9g were used. The experiment was a 2 x 4 factorial laid in completely randomized design (CRD) with three replications. Eight treatment combinations were randomly distributed. Fruits were stored for seven days and were observed every 2 days. Result revealed that packaging material influenced postharvest ripening of garden egg with polythene bag reducing the intensity of ripening and significantly reduced shrinkage. Similarly, KMnO4 at (3g and 9g) significantly delayed ripening intensity at 4 and 6 days of storage. PubDate: 2022-04-21 DOI: 10.20448/aesr.v9i1.3865 Issue No:Vol. 9, No. 1 (2022)
