However, national food production still doesn't meet the requirements of the population. The decrease in food production caused by crop-failures, significant seasonal fluctuations, lack of appropriate and affordable preservation and storage systems can be resolved by way of drying. Locally, crop drying has been accomplished by burning wood and fossil fuels in ovens or outdoors drying under screened sunlight. These methods, however, have their shortcomings. The previous is expensive and not environmental friendly and the latter is vulnerable to the variability and unpredictability of the weather. This paper discusses the development of a hybrid solar food dehydrator using locally available materials like plywood, wire mesh, and a glass, to supply an honest method for food preservation that maintains a high level of flavor and nutrients, at the same time providing a convenient, compact, easy-to-store supply of Agricultural produce at a far lesser cost.","PeriodicalId":138819,"journal":{"name":"AFRICAN JOURNAL OF SUSTAINABLE AGRICULTURAL DEVELOPMENT","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134066723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"ASSESSMENT OF ROLES OF TREES TO RURAL LIVELIHOOD IN BUNZA LOCAL GOVERNMENT, KEBBI STATE","authors":"I. Umar, FU Zogirma, DP Gwimmi, A. Ambursa, A. Abdulrahman, M. Mustapha","doi":"10.46654/2714.14126","DOIUrl":"https://doi.org/10.46654/2714.14126","url":null,"abstract":"The importance of tree to people and the environment was the aim of this paper. The Research was carried out at Bakura Local Area of Kebbi State. Questionnaire was used to get feedback from the farmers. The results that show the socio-economic status reveal that most of the dwellers in the local government use trees for shelter, food, medicinal, fodder, and fuel wood. Majority of the respondents (57.1%) in the area reported that they were married, (24.3%) were single, divorce (16.8%) while widows have (1.5%). This indicated that majority of the respondents have family responsibilities to cater for which affecttheir farming activities. Majority of students were male and only few were female, adults dominate the study area. On the education level, it was reported that primary education recorded (30%) of the respondents in the study followed by tertiary education (27.1%), secondary education had (11.5%) while quranic education had (15.9%). It is recommended that farmers should practice agro-forestry services, because of its dual benefits that people got from it and it also leads to successful recycling of nutrients and soil protection as well as improving their livelihood and agricultural production. Government should provide alternative source of living in the area so as to reduce the pressure on forest trees.","PeriodicalId":138819,"journal":{"name":"AFRICAN JOURNAL OF SUSTAINABLE AGRICULTURAL DEVELOPMENT","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130311713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"ASSESSMENT OF ANTHROPOMETRIC AND IRON STATUS OF SCHOOL CHILDREN IN SOMOLU LOCAL GOVERNMENT AREA OF LAGOS STATE, NIGERIA","authors":"A. Ifebajo, W. Afolabi, S. Sanni, O. Onabanjo, A. Ariyo","doi":"10.46654/ij.24889849.a61015","DOIUrl":"https://doi.org/10.46654/ij.24889849.a61015","url":null,"abstract":"Iron is essential for children's cognition because it enhances behavioural and intellectual performance and promotes the body's resistance to infections. However, the risk of iron deficiency increases during period of rapid growth notably among school aged children in developing countries. This study assessed the anthropometric and iron status of school children in Somolu Local Government Area of Lagos State. Somolu Local Government was selected using purposive sampling. One hundred and forty school children (8-12 years) were selected from 3 primary schools using multistage sampling technique. Socio economic data were collected using structured questionnaire. Nutritional status of pupils were assessed using anthropometric measurements while iron status was determined using biochemical analyses of serum ferritin (SF), packed cell volume (PCV) and haemoglobin (H-B). Socio economic data were analysed with descriptive statistic (frequency, mean and percentages). While Chi-square and Pearson product moment correlation were used to establish relationship between variables. Pattern of dietary iron sources intake of the respondents were determined using food frequency questionnaire. Result showed that mean values of weight, height, haemoglobin, packed cell volume and ferritin were 43.82kg, 141.67cm, 11.50g/dl, 33.91% and 49.10ng/l respectively. Results of Anthropometric assessment indicated that 18.2% of female and 12.7% male were stunted; 15.6% of female and 14.30% of male were wasted, while 27.3% of the female and 23.0% of the male were underweight. 67% of the subjects had normal ferritin (15-100ng/l), 19.0% had low ferritin (<15ng/l) while 14.3% had abnormal high ferritin (>100ng/l). The respondents (14.3%) whose ferritin level were exceedingly high (>100ng/l) belong to AC (4.7%), SC (3.5%), and SS (6.1%) genotype blood groups. Findings also revealed that 24.2% of the male and 33.0% of female respondents were anaemic (Hb <11g/dl). 81.43% of the respondents consume less of iron rich food. The haemoglobin levels of the male respondents were found to be positively correlated with their BMI. (r = 0.289, P > 0.05). There was a positive correlation between PCV and BMI of male respondents (r = 0.209., P < 0.05). Furthermore, there was a relationship between blood Ferriftin and genotype of both male and female respondents respectively (r = 0.276, P < 0.05), (r = 0.341, P < 0.05). A positive correlation existed between ferritin and food intake pattern of female respondents (r = 0.288, P < 0.05). There was a negative correlation between iron status and income of the respondents' parents, (r = 0.276, P < 0.05). In conclusion, this study has ascertained that there is stunting, wasting, underweight and iron deficiency among school children in Somolu Local Government Area of Lagos State. It is recommended that appropriate intervention should be introduced to reduce the prevalence of iron deficiency among school aged children in Somolu Local Government Area.","PeriodicalId":138819,"journal":{"name":"AFRICAN JOURNAL OF SUSTAINABLE AGRICULTURAL DEVELOPMENT","volume":"358 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134292403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
