A Systematic Review on the Role of Distributed Ledger Technology for Agricultural Traceability

Authors: Rey A. Castillo, Gilbert M. Gord, Vera Kim S. Tequin, Rizamae S. Palen, Hazel Mae Limbago-Villa, Justine Johannes P. Doot and Ronmar S. Sabado

Abstract: Several industries, among them agriculture, have shown interest in distributed ledger technology (DLT). The researchers explore how DLT can be used in agriculture, with a focus on its potential to disrupt supply chain management and enhance transparency. Furthermore, DLT has the possibility of greatly improving agriculture through addressing issues such as traceability, origin, and information sharing. The implementation of DLT will allow every player along the entire agricultural supply chain, such as farmers, producers, distributors, retailers, and consumers, to possess clear, immutable records about each transaction while promoting accountability and confidence in the market. The study used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. The results of the systematic review shown in this paper suggest that DLT has the potential to revolutionize the agricultural sector by providing a secure and transparent system of data storage and sharing.

A Comparative Analysis of the Profitability of Artisanal Fishing Affected by Oil Spill and Non-Oil Spillage in Bayelsa State

Authors: Wilcox GI and Chiedozie-Ejezie NS

Abstract: This study compared the profitability of artisanal fishing households in Bayelsa State's oil spill-affected areas and non-oil spill-affected areas. The study's objectives were to determine the respondents' sociodemographic status and to compare the profitability of both oil-spill and non-oil-spill artisanal fishing activities. A multistage sampling method was used to select 200 respondents (100 each from the crude oil spilled and non-crude oil spilled areas). A structured questionnaire was used to collect primary data for the study. The collected data was analysed using descriptive statistics and budgetary analysis. The principal findings of the study were that men made up the majority of respondents (77%) in both areas.

Effects of Lime, Inorganic Fertilizer and Compost as Amendment on Soil Chemical Properties: Field Experimental Approach to Reclaim Acidic Nitisoils, South Western Ethiopia

Authors: Tadie Girma Dadi and Alemayehu Regassa Tolossa

Abstract: Soil acidity is a series problem in south western part of Ethiopia due to high rainfall that aggravates the concentration of toxic elements like Al and Fe. This study was conducted to evaluate the effects of lime with different fertilizer sources on soil chemical properties at Seka chekorsa area. Seven different treatments were applied with randomized complete block design along three replications. The study pointed out the response of soil pH, H + , Al 3+ , Exchangeable Acidity, Available and CEC were attained significant difference at (p < 0.05) in ½ Compost plus lime treated plot.
