six pages, The sustainability of organic agriculture is associated with the farmers’ experience, quality of information provided, management of risks, and compliance with legislation. The objectives of this study were to identify the sources used by the organic farmers to gain information related to organic production, and to assess organic farmers’ perceived attitudes towards extension services. To address the research objectives, in-depth semi-structured interviews were conducted with 10 organic farmers in central Pennsylvania. The interviews were digitally recorded and transcribed verbatim, categorized and coded, then thematically analyzed using an interpretive description methodology. The results showed that the extension services were not identified as a primary source of information that was frequently used by the organic farmers. Other organic farmers and organizationa for organic agriculture were the two primary sources of informaiton. The organic farmers were very adept at building social capital in seeking informaiton to address their issues and problems. The primary challenges faced by the organic farmers were the control of insects and weeds, and weather-related issues. The results highlighted that in addition to identifying viable information sources, factors such as adaptive capacities to climate change and certification were key to successful production in organic systems. The present study provides rich and deep information on how farmers perceive organic agriculture and extension services. The outcome of the research undertaken will enable planners, policy makers and the related Cooperative Extension personnel to better understand perceptions of the farmers to devise viable and workable policies and plans that address the concerns and challenges of the farmers.
2 pages, For years agroecologists have warned that industrial agri-culture became too narrow ecologically, highly dependent on outside inputs, and extremely vulnerable to insect pests, diseases, climate change and now as demonstrated by the COVID19 pandemic prone to a complete shut down by unforeseen crisis.Like never before, COVID19 has revealed how closely linked human, animal and ecological health are. As a power-ful systemic approach, agroecology reveals that the way we practice agriculture can provide opportunities for improv-ing environmental and human health, but if done wrongly, agriculture can cause major risks to health.
24 pages, In this work, an exhaustive revision is given of the literature associated with advanced information and communication technologies in agriculture within a window of 25 years using bibliometric tools enabled to detect of the main actors, structure, and dynamics in the scientific papers. The main findings are a trend of growth in the dynamics of publications associated with advanced information and communication technologies in agriculture productivity. Another assertion is that countries, like the USA, China, and Brazil, stand out in many publications due to allocating more resources to research, development, and agricultural productivity. In addition, the collaboration networks between countries are frequently in regions with closer cultural and idiomatic ties; additionally, terms’ occurrence are obtained with Louvain algorithm predominating four clusters: precision agriculture, smart agriculture, remote sensing, and climate smart agriculture. Finally, the thematic-map characterization with Callon’s density and centrality is applied in three periods. The first period of thematic analysis shows a transition in detecting the variability of a nutrient, such as nitrogen, through the help of immature georeferenced techniques, towards greater remote sensing involvement. In the transition from the second to the third stage, the maturation of technologies, such as unmanned aerial vehicles, wireless sensor networks, and the machine learning area, is observed
