L’ouest du Rio Grande do Sul est dominé par la culture du soja, du riz et par l’élevage bovin. Dans la partie sableuse, le milieu est affecté par des phénomènes d’érosion produisant des modelés éoliens spectaculaires (arenização) rappelant dans l’imaginaire ceux des déserts. La production agricole est importante ce qui engendre des prélèvements d’eau pour l’irrigation du riz, mais aussi l’utilisation de pesticides pour l’ensemble des cultures. La gestion durable des ressources en eau et en sol de cette région nécessite la mise en place d’action de conservation.
La consommation de produits certifiés n’est plus l’apanage des pays développés. Au Kenya, les premiers marchés biologiques sont apparus à Nairobi en 2006. Ils sont approvisionnés par des maraîchers, confrontés à une diversité de défis : construire une certification biologique crédible, garantir la fraîcheur des produits et composer avec l’hétérogénéité des attentes des consommateurs. À partir de données d’enquête et du cadre analytique des coûts de transaction, nous analysons l’organisation des marchés de 2006 à 2013.
L’information agricole est l’élément instrumentant le quotidien de l’agriculteur. Mais, les nombreuses politiques agricoles mises en place au Cameroun n’ont pas toujours facilitées la diffusion et l’accès à l’information agricole. Les agriculteurs ruraux n’ont accès qu’à une infime quantité d’informations sur l’agriculture, malgré l’énorme corpus de connaissances existant dans les instituts de recherche, les universités, les offices et les bibliothèques. Fort de cela, il serait judicieux dans la présente étude, de faire un examen des besoins en information des agriculteurs de la Menoua.
This article examines differences in the research approaches of farmers and scientists and analyzes how these differences are related to the conditions under which both groups engage in experimental work. Theoretical considerations as well as practical experiences are presented to emphasize the great potential of farmer–researcher collaboration for rural innovation.
The main purpose of this study was to institutionally map nanotechnological innovation system of Iranian agriculture by investigating current state of hard and soft institutions regarding functions of the system. This study consisted of qualitative and quantitative phases. In the qualitative part, a thematic content analysis was used to compare the current and desired states of high level laws and documents. The quantitative phase was a descriptive survey.
Recently, innovation has become a very important issue, as it provides a strategic advantage for organizations to outperform competition and remain agile in the environment. Additionally, knowledge management is considered to be a strong support for innovation. However, few studies examine the role of human resource management in fostering knowledge capability which leads more innovation in the organizations. The purpose of this study was to examine the role of knowledge management components in organizational innovation among agricultural extension experts in Khuzestan Province.
Agricultural professionals play an important role in informing and educating farmers about biofuel through teaching or extension work. One of the questions commonly asked is if they are knowledgeable and possess positive attitude towards renewable energy sources. The aim of this article is to investigate Agricultural professionals' attitude and willingness towards biofuel using a random sample of professionals (n = 180) in a survey conducted in Zanjan province in Iran
Iran faces environmental challenges such as erosion and extreme events, namely droughts and floods. These phenomena have frequently affected the country over the past decades and temperature rise has led to a more challenging situation. Iran started to implement national and provincial policies in the 1950s to cope with these phenomena. To provide an overview of Iran’s efforts to tackle land degradation and climate change, this paper examined through literature since 2000 the stakeholders’ policies, their interventions and obstacles to the mitigation of these environmental challenges.
Agricultural extension, as an informal educational system, is one of agricultural development tools that lean on human capitals. Inefficiency of public bureaucracy on the one hand, and managerial problems on the other hand, as well as neglecting real needs of beneficiaries in planning, have determined responsible to transfer administrative tasks to the private sector and reduce government's tenure. This survey was conducted in Kerman as the first ranked province of pistachio production in Iran to investigate attitudes about extension private services among pistachio farmers.
Integrated Pest Management (IPM) is considered as an ecological conservation technology for crop pests' management; however, the technology adoption is intensely affected by surrounding socio-psychological environment, which is poorly studied, particularly in developing nations. The present study therefore aimed at addressing this gap through application of an extended form of Technology Acceptance Model (TAM) in order to examine the determinants of Iranian farmers' ecological conservation behavior regarding the use of IPM practices.
