Meaning that without drastic action, the world food crisis will continue to persist and many people around the world will continue to live in abject poverty. To avert this ongoing phenomenon, this paper examines how the global food system and human health can be improved and poverty alleviated through small ruminant production; and how Nigeria will benefit from it. To properly articulate the theme of this paper, the discussion will focus on what small ruminant animals are; their benefits and constrain; the global food system, small ruminant production and its relation to human health and poverty eradication, efforts at improving small ruminant production and how this will have an impact on the Nigerian economy.

Specifically, the study examined the; fish farming systems; cost and returns, socio-economic determinants of net-farm income and challenges of fish farming in the area. The study adopted a two-stage sampling procedure to select 120 table-size fish farmers. Data were collected with questionnaires that were administered through face-to-face interview and analyzed using descriptive statistics, budgetary technique and multiple regression analysis. The results showed that 35.00 % of the fish farmers were within the age bracket of 31-40 years, 53.34 % were men, 91.67 % were married, 55.83 % had between 1-5 years of experience in fish farming and 75.83 % had tertiary educational qualification. Majority (92 %) of the fish farmers practiced the monoculture of catfish using earthen ponds system. The estimated total expenses were N 14,953,330.74 while the total revenue generated from 9 fish ponds, each stocked with an average of 3883.986 fingerlings in 2 cycles per year was N 20,188,142.00. The estimated net-farm income after tax was N 5,234,811.26 while the net profit margin and return on investment was 25.93 % and 35% respectively.

The specific objectives were to; identify the types of ICTs available to yam farmers, ascertain the level of awareness of ICTs among yam farmers and ascertain the effects of ICTs on yam production in the study area. Questionnaires were used to obtain data from respondents for the study. Data were analyzed using descriptive statistics such as frequency, percentage, mean and ranks. Result of types of ICTs available among the yam farmers showed that radio was ̅=3.70, Mobile phones were ̅=3.50 while television had ̅=3.11 and were the most available ICTs accessed by yam farmers in the study area. Findings on the level of awareness indicated that Radio ( ̅=1.78) ranked 1st, television ( ̅=1.70) ranked 2nd while, mobile phone ( ̅=1.66) ranked 3rd and were the ICTs that the farmers had greater awareness. Results on the perceived effects of ICTs on yam production revealed that ICTs reduce cost of interaction among yam farmers, enhanced decision-making among farmers and also strengthen partnership with research and extension. However, serious constraints to the use of ICT facilities by farmers were identified such as; poor finance, erratic power supply and cost of use of ICT tools. The result of this study showed that yam farmers in Ikom Agricultural Zone utilized conventional ICTs tools more than contemporary tools in yam production.

A three stage multi sampling technique was adopted in the selection of 180 respondents. Data collected were analysed using descriptive statistics such as frequency, mean, ranking and percentages, as well as budgeting techniques tools such as net farm income (NFI), return to naira invested (RNI), gross and operating ratios (GR and OR) respectively. Result of analysis showed that socio-economic attributes of broiler farmers - age, sex, marital status, education, experience, business size and training studied influenced on broiler production in the area. Furthermore, the study revealed that broiler production is a profitable venture in the area. This is arising from the difference between a total revenue of N704, 000 and total cost of N419, 153 respectively, representing a net profit of N284, 646.6 or 67.90% of the total amount of money invested, within a production season of eight weeks. The return per naira invested ratio was 1.64, this meant that for every naira invested, N1.64 profit was made by the broiler farmer, this further indicated that the business is profitable. The gross ratio, which measured the overall financial success of the business recorded 0.61. However, cost of feeds, lack of extension services, financial constraints, cost of day old chick’s medication among others are the constraints affecting effective broiler production in the area. Based on the findings of this study, the following are recommended: regular extension training on broiler production should be carried out by the relevant government agencies, feeds should be subsidized and made easily available by government, production of day old chicks should be subsidized by government to cushion the effect of their high cost and livestock farmers should be encouraged to invest on the poultry subsector for it profitability.","PeriodicalId":250072,"journal":{"name":"Global Journal of Agricultural Sciences","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114345990","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}

The result showed that all the variables were integrated of order one. The results revealed that credit rationed for fishery has a short-run significant impact on agricultural output while credit rationed for cash crops, food crops, and livestock do not have a significant short-run impact on agricultural output. The findings further revealed that credit rationed for cash crops and livestock farming significantly decline agricultural output to the tune of 26.48% and 75.87% in the long run while credit rationed for food crops and fishery significantly result in 43.52% and 41.89% rise in agricultural output in the long run. Therefore, the study recommends the establishment of special financial institutional to give unconditional loans to farmers, raise credit rationing for food crop production above the current ceiling, and emphasis should be on exchange rate liberalization policy that will shift consumption from imported agricultural produce to local agricultural produce. These measures will promote farmers’ access to funding which will invariably translate to a rise in agricultural output.","PeriodicalId":250072,"journal":{"name":"Global Journal of Agricultural Sciences","volume":"135 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":"133131753","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}

Length frequency data were analyzed using FiSAT software to estimate population parameters. The asymptotic length, L was 105 cm, growth constant (K) was 0.68 year -1 , total mortality (Z) was 2.48 year -1 , Natural mortality (M) was 0.99 year -1 and fishing mortality (F) was 1.49 year -1 . The exploitation rate was 0.60 year -1 , indicating overfishing. Natural mortality accounted 40% of the total mortality, presenting a worrisome trend in the fishery. There was a correlation between rainfall and catch rate, which increased at the onset of rains but decreased at the peak of the rains due to increased depth of the river. For management purposes, it is recommended that the fishing effort should be reduced by the regulation of the number of boat-days; for conservation, domestication of the species should be adopted as an adaptation to climatic influence.","PeriodicalId":250072,"journal":{"name":"Global Journal of Agricultural Sciences","volume":"35 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":"115171555","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}
