8 pages, via Online journal, The use of tomato (Solanum lycopersicum) grafting is gaining traction across the United States, but small-scale growers face the challenge of creating optimum postgrafting healing conditions. The practice of blocking light for a period of 2 to 4 days while maintaining high humidity is commonly recommended for healing grafted tomato transplants; however, research is exploring alternatives to this practice. The present study investigated a low-input healing method for grafted tomato transplants with a specific focus on light and the use of propagation heat mats to regulate substrate and healing chamber air temperatures during the 7-day healing process. We hypothesized that 4 days of light exclusion and the use of propagation heat mats would improve grafted tomato transplant survival and growth. ‘Cherokee Purple’ was used as the scion and ‘RST-04-106-T’ was used as the rootstock. The whole plot factor was heat [propagation mats set at 80 °F (heat) or no propagation mat (no heat)] and the subplot factor was light exclusion (0, 4, or 6 days of dark). The highest survival rate among treatments was 97% in 0 days of dark with no heat treatment; survival decreased to 84% in 4 and 6 days of dark with no heat treatments. The plant survival rate was 96% with 0 days of dark and heat treatment; however, the survival rates were 63% and 45% for the 4- and 6-day dark treatments, respectively. The scion stem diameter was largest for transplants grown in 0 days of dark, but there was no difference in stem diameter due to heat treatments. There were no differences among scion or rootstock biomasses due to heat or light treatments. These results demonstrate that propagation mats set at 80 °F to regulate the substrate temperature were detrimental to grafted transplant survival under extended periods of light exclusion. However, this finding creates the basis to explore lower levels of substrate temperature modification. Our work also indicates that light exclusion may not be necessary for healing grafted tomato plants regardless of root-zone temperature treatments. Future work should examine the interactions of various substrate and air temperatures under full light conditions and their effects on grafted tomato transplant survival and growth. This work contributes to the ongoing research of how to optimize low-input healing methods that may be readily adopted by small-scale tomato growers.
19 pages., To harness the potential of Information and Communication Technologies (ICTs), developing countries need to develop national ICT policies that will serve as a framework for integrating ICTs at all levels of society. In the absence of that, different actors often engage in various actions for the same beneficiaries and in pursuit of the same objectives. That raises the need to define a national framework for the promotion and application of ICTs in the various production areas, particularly agricultural ones. It is for that reason that this study examined through qualitative methods (policy documents and semi-structured interviews) the national policy of Mali on the use of ICTs in agriculture. Data was analysed using the Qualitative Content Analysis (QCA) method with the aid of NVIVO 12 software. The results showed that the country has two policy documents that articulate the country’s strategy towards the use of ICTs in the agricultural sector, that is, the Agricultural Orientation Law and the National Strategy for the Development of the Digital Economy. Further examination revealed that that these two policy documents are neither appropriate nor coherent in today's Malian landscape. This has resulted in an underutilisation of digital tools by agricultural extension officers which led to the low agricultural productivity in the country. This study recommended therefore the recasting of both documents to take into account the reported observations
4pgs, Online from publication., Describes the U.S. Census Bureau's decision to pull the agency's enumerators out of the field due to COVID-19 with about one-half of the state's remote villages uncounted. A legislator representing that area described this as "a politically motivated effort to undermine our political clout and to strip us of resources." The Native Voice Network, a nationwide coalition of 40 Native-led organizations was among those pushing Congress to complete the census for an accurate count.
17 pages, California is severely exposed to drought and damage due to the climate change and drought belt, which has a major impact on agriculture. So, after the drought crisis, there are various reactions from farmers. The extent of the damage caused by the socioeconomic, environment and the extent of the resistance of farmers to this crisis is manifested in a variety of ways. Recognizing the population’s resilience and the involved human groups is a tool for preventing a catastrophe-based increase in life-threatening areas in high-risk areas. Sometimes the inability to manage this phenomenon (especially under the climate change) leads to farmers’ desertification and agricultural land release, which itself indicates a low level of resilience and resilience to the crisis. The recent drought under the climate change condition in California and the severity of the damage sustained by farmers continue to be vulnerable. The present study seeks to prioritize and prioritize resilience of farmers to the crisis under the climate change. This study simulated drought condition with using PDSI value for current and future time period. In order to calculate PDSI values, the climatic parameters extracted from CMIP5 models and downscaled under the scenario of RCP 8.5. Also in order to understand the resilience of the agriculture activities under the climate change, this study was performed using statistical tests and data from the questionnaire completed in the statistical population of 320 farmers in the Tulare region in California. The findings of the research by t test showed that the average level of effective factors in increasing the resilience of farmers in the region is low. This is particularly significant in relation to the factors affecting government policies and support. So that only the mean of five variables is higher than the numerical desirability of the test and the other 15 variables do not have a suitable status for increasing the resilience of the farmers. Also, the results of the Vikor model showed that most of the impact on their resilience to drought and climate change was the development of agricultural insurance, the second important impact belongs to drought monitoring system, climate change and damage assessment, and variable of attention to knowledge is in third place of the important factor.

11 pages, Diversifying a farm's production operations or marketing channels can boost income and raise farm survival rates. But are beginning and small-scale farmers inclined toward a strategy of diversification? We analyzed 578 attendee surveys from 10 years of an Extension workshop for new and small-scale farmers in Ohio. We investigated the farming profile of beginning and small-scale farmers, the degree to which they are interested in pursuing diversified farming, and whether these interests vary by gender. We found evidence that new and small-scale farmers are interested in alternatives to commodity grain farming, that these alternatives are associated with diversified farming systems, and that some specific diversification interests vary by gender.
12 pages., Digitalization is a key enabler of sustainable development of cities’ socio-economic dynamics with the potential to foster climate-friendly urban environments and societies. The advent of the 4th industrial revolution has seen the increased application of digitalization in several fields and at different levels. High-tech digital devices, platforms and environments are increasingly being deployed to enhance productivity, efficiency and sustainability, and improve overall well-being of urban dwellers. Digitalization is projected to further impact cities in future, transform jobs and trigger life-style changes with far-reaching impacts that will ultimately affect cities’ resilience and adaptation capacities. While a growing body of research has highlighted the significance of digitalization to climate change mitigation such as reducing GHG and CO2 emissions, comprehensive evaluations of the potentials of digitalization as an enabler of climate change adaptation remain scarce. This paper addresses this gap by analysing the current trend in digital revolution in relation to climate change adaptation and examines the likely challenges of digitalization. A desk research method was adopted, focusing on core digitalization concepts driving the Fourth Industrial Revolution (IR 4.0). Nine case studies in cities across various continents were selected to assess the potentials of digitalization in addressing climatic hazards and to highlight benefits from implementing digitalization, while considering the social-ecological-technological challenges and tensions around IR 4.0. Our findings reveal the capabilities of digitalization in supporting more effective early warning and emergency response systems, enhancing food and water security, improving power infrastructure performance, enabling citizen engagement and participatory adaptation measures and minimizing the impacts of climatic hazards. Finally, we recommend feasible pathways to overcome present risks and challenges in order to optimize the numerous opportunities offered by digitalization in support of climate change adaptation initiatives.
7 pages, To assess small rural retailers' use of social media and the role of social media in their business sustainability, we conducted focus group interviews with small business owners/managers from rural communities in a midwestern state. Participants revealed strong interest in social media, especially for use in sales and marketing. However, their engagement in social media was limited due to lack of knowledge and resources (i.e., time, human resources, financial resources, effectiveness measurement) related to developing and updating content. On the basis of these findings, we examine implications for Extension professionals and outreach educators regarding social media needs and programming for small rural businesses.
3 pages, Big data represent a new productive factor (the "new oil" for advocates) that generates new realities in agriculture. By adding an extra "cyber" dimension to current farming systems, big data lead to the emergence of new, complex cyber-physical-social systems. However, our understanding of the sustainability of such systems is still at a rudimental stage. In this critical review we attempt to shed some light on this topic, by identifying and presenting some issues that put in doubt the sustainability of big data agriculture. By using a punctuated equilibria lens, we argue that despite their contribution to the economic and environmental performance of farming, big data act as a speciation mechanism. Hence, they lead to new forms of intraspecific, interspecific and intergeneric competition, thus putting at risk the most vulnerable players of the game. We conclude by pointing out that to holistically address the interrelation between big data and agricultural sustainability we need a hybrid research line, which will combine the qualities of both technology-oriented research and critical social science.
21 pages, via Online Journal, This paper explores the role of regulation and legislation on influencing the development and diffusion of technologies and methods of crop production. To do this, the change in pesticide registration under European Regulation 1107/2009 ‘Placing Plant Protection Products on the Market’ was followed through the UK’s agricultural system of innovation. Fieldwork included: a series of interviews conducted with scientists, agronomists and industry organisations; a programme of visiting agricultural events; as well as sending an electronic survey to British potato growers. The innovation system is noted to have made the legislation less restrictive than originally proposed. The most notable system response to the legislation is the adjustment of agrochemical company pesticide discovery strategy and their expansion into biologically derived treatments. There have also been other innovation responses: agricultural seed companies have been breeding in pathogen resistance in their cultivars; agricultural consultancies are prepared to recommend pathogen-resistant seeds; scientists are using the change as justification for adopting their solutions; the agricultural levy boards funded research into off-label pesticide uses; and producers, potato growers in particular, have been seeking advice, but not changing their growing practices.
