RESUMO: O objetivo do presente estudo é avaliar as decisões dos agricultores de adotar a agricultura orgânica. Foi introduzido pela primeira vez por países desenvolvidos para minimizar os impactos ambientais originados pelo uso intensivo de fertilizantes sintéticos e pesticidas para aumentar o rendimento da produção. Embora a agricultura orgânica ofereça metodologias ambientalmente corretas para a produção agrícola, os agricultores asiáticos relutam em adotar a agricultura orgânica. Neste estudo, uma análise de sobrevivência (SA) foi empregada para determinar os motivos e o tempo que os agricultores levam para adotar a agricultura orgânica. Esta pesquisa estudou os objetivos dos agricultores, as políticas agrícolas e a atitude em relação ao risco, como covariáveis na análise de sobrevivência. Um método de tomada de decisão de múltiplos critérios com base no Processo de Hierarquia Analítica foi usado para avaliar os objetivos dos agricultores. Os dados foram coletados em fazendas agrícolas localizadas em três distritos de Punjab, Paquistão. Um questionário foi usado para coletar evidências empíricas. Este estudo descobriu que os objetivos dos agricultores eram cruciais para aceitação da agricultura orgânica; além disso, jovens agricultores e agricultores com atitudes inclinadas ao risco eram mais propensos a adotar a agricultura orgânica. O estudo também determinou que a mudança na política e a introdução de um pacote especial para a agricultura orgânica podem estimular a adoção de métodos orgânicos.

ABSTRACT: This research evaluated farmers’ decisions to adopt organic farming. It was first introduced by developed countries to minimize environmental impacts originated by intensive use of synthetic fertilizers and pesticides to enhance production yield. Although, organic farming offers environmentally sound methodologies for crop production, but Asian farmers are reluctant to adopt organic farming. In this study, a survival analysis (SA) was employed to determine the reasons for and the time is taken by farmers to adopt organic agriculture. This research studied the farmers’ goals, agricultural policies, and attitude towards risk, as covariates in the survival analysis. A multiple criteria decision-making method based on the Analytic Hierarchy Process was used to evaluate the farmers’ goals. Data were collected from agricultural farms located in three districts in Punjab, Pakistan. A questionnaire was used to collect empirical evidence. This study reported that the farmers’ goals were crucial to their acceptance of organic farming; furthermore, young farmers and farmers with risk-inclined attitudes were more prone to adopting organic farming. The study also determined that change in policy and introduce special package for organic agriculture can encouraged the adoption of organic methods.

Abstract Food is a basic human right since it is necessary for survival. Unsafe food threatens billions of people throughout the world. Every year, hundreds of thousands of people grow sick and die. Microbial, chemical, personal, and environmental hygiene are all issues that the food chain faces from farm to fork/plate. Human tragedies and economic disasters have been reported in the past as a result of purposeful or inadvertent personal behavior and government inability to ensure food safety and quality. The issue of food safety has gotten a lot of press. As a result, a Food Safety Information Platform (FSIP) based on machine learning and open data with a Chatbot based on cloud computing (MLODCCC) architecture was developed, which includes a nice Facebook hyperlink and chatbot interface for locating trustworthy food safety knowledge. Rumors about the safety of food goods instill fear in people, leading to a broad boycott and, as a result, significant economic loss. This study looked into the function of rumors among friends. The findings suggested that people choose to use news media information in interaction with friends because it is seen to be more reliable than other resources.

Abstract This pagination specifies the characteristics of Cattaneo-Christov heat diffusion model for the stagnation point flow of a Carreau nano-fluid. The momentum equation is manifested with magneto-hydrodynamic effect and the generalised Fourier’s law and Fick’s law are considered to manipulate the heat and mass flux with heat generation and chemical reaction. The fluid flow having infinite shear rate viscosity is caused by the stretched sheet. The admissible transformations are invoked to alter the flow narrating coupled partial differential system into the coupled ordinary differential system. Later on, these equations are sorted out numerically with the aid of Runge-Kutta Fehlberg method supported with shooting scheme. The graphs are plotted that portrays the impact of fluid velocity and temperature towards various engineering parameters which reveals that the fluid temperature increases when enlarging heat generation parameter. The validations for the numerical values of skin friction coefficient are delineated with the existing literature. Also, the numerical findings for the local Nusselt number are offered.
