14 Pages, iZindaba Zokudla (IZ) is a multistakeholder engagement project that aims to create opportunities for urban agriculture in a sustainable food system in Johannesburg. IZ implements the Farmers’ Lab, a social lab used as a transitional mechanism in a larger transition to sustainability. To move the South African urban food system to an ecologically sound, economically productive, and socially equitable system, significant stakeholder integration is needed, and the iZindaba Zokudla Farmers’ Lab provides that. This reflective essay presents a history of the project (2013 until now) detailing the project’s creation of an ecosystem based on social labs that facilitate innovation in the food system. Emergent entrepreneurs and others use the social labs and their activities, as well as stakeholder engagement in their enterprise development, and these Labs have created opportunities for applied and other research in the university. This has brought innovation and change to agroecological practice in Johannesburg. This reflective essay article situates IZ within the broader evolutionary change in South Africa and considers how conversations about food lead to the creation of sustainable food systems.
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.

14 Pgs., Although climate information can aid farmers’ capacity to adapt to climate change, its accessibility and adoption by subsistence farmers hinge on the collaboration between farmers and climate information providers. This paper examines collaborations among actors in the process of climate information production and dissemination in the Namibian agricultural sector. The aim is to investigate the extent to which subsistence farmers are integrated into the collaboration process and the impact of the collaboration on the nature and accessibility of disseminated information. Key informant interviews and a questionnaire survey were used for data collection. Using network analysis, we estimated the networks’ density, clustering coefficient, and degree centrality. The study found that both the climate information production and dissemination networks have a high overall clustering coefficient (78% and 77%, respectively) suggesting a high rate of collaboration among the actors in the networks. However, the frequency of interactions between the actors in both the information production and dissemination networks and subsistence farmers remains very low. Nearly all surveyed farmers reported that they meet with information providers only once in a year. The effect of this poor interaction is reflected in the poor occurrence of feedback learning, which is needed to optimize channels of information dissemination to subsistence farmers and enhance the robustness of disseminated information. We recommend innovative communication means via mobile phone, promotion of peer-to-peer learning, flexible collaboration relations with more space for feedback from the users of climate information, and more attention to long-term forecasts and their implications for adaptive actions.
An analysis of secondary data from the National Panel Survey in Tanzania revealed physical, socioeconomic, and institutional factors influencing the adoption of soil conservation technologies among small-scale maize farmers. Findings revealed, for example, only 13.9 percent of those had adopted soil conservation technology. This was cited as small, compared with other countries.
12 pages., Online via Directory of Open Access Journals (DOAJ)., Findings showed that women smallholders' uptake was affected by limited access to credit, extension, restricted membership in cooperatives and water user associations, lack of access or user rights to land, skill training, information, and restricted mobility. Authors suggested that expanding off-farm diversification and rural employment opportunities through changing the land tenure system, which is currently state-owned, are essential to enhance women smallholders' access to land and other agricultural inputs.
11 pages., In 2016, a study was conducted in Tanzania to assess the impact of radio and SMS in scaling-up smallholder participation in legume-based sustainable agricultural intensification (SAI) practices and technologies. The study aimed to answer the following research questions: (i) does participation in the campaign enhance farmers’ knowledge of legume-based sustainable agricultural intensification practices and technologies? (ii) what is the impact of the campaign on the adoption of legume-based sustainable agricultural intensification practices and technologies?; (iii) does exposure to multiple ICT-enabled channels result in larger gains (in terms of knowledge and adoption) than exposure to only one channel? (iv) is it more cost-effective to use radio or SMS alone or use them in combination? The results show that both awareness and adoption are boosted if SMS supports radio campaigns. However, radio alone is the most cost-effective approach. Each dollar spent on the radio campaign results in 2.1 farmers that have adopted at least one new practice, compared with 0.5 farmers for SMS and 0.4 farmers for radio and SMS combined. Other factors were also important in facilitating uptake of legume-based SAI practices, such as gender, age, education and land size, but were not statistically significant when rated against the communication channels used.
Online via subscription. 5 pages., Article summarizes results of a survey among farmers and consumers conducted by Aimpoint Research for The Packer. Findings showed that growers believe they best understand sustainability while believing that very few if any food retailers and consumers completely understand it. Nearly two-thirds of surveyed consumers said they believed sustainability efforts from the food industry are a response to their demands rather than industry driven by industry while two-thirds of growers said they believe sustainability efforts are industry driven. Report also compared beliefs by growers and consumers about where they get sustainability information.
7 pages, Use of cover cropping systems has multiple benefits for agriculture. To convince vegetable growers to adopt such systems, we applied a field demonstration in which we grew selected cover crops during the off-season and then tomatoes. We focused on implementation of a science-based demonstration design and attended to the usefulness of the demonstration and audience timing preferences. As a result, growers grasped the advantages of growing cover crops and, consequently, have extensively adopted cover cropping systems, thereby applying a critically important practice for crop management and agricultural sustainability. Our method and findings can help Extension educators better implement programs to convince agricultural producers to adopt desirable farming practices that improve sustainable agriculture.
21 Pages, Agricultural advisory services generally rely on interpersonal knowledge transfers by agricultural extension agents who visit farmers to provide information. This approach is not always effective and has proved hard to scale sustainably, particularly in highly dispersed smallholder farming systems. Information and communication technologies (ICTs) have been advanced as a promising way to overcome many of the problems associated with conventional agricultural extension. We evaluate the effectiveness of an ICT‐mediated approach to deliver agricultural information in a field experiment conducted among small‐scale maize farmers in eastern Uganda. Three complementary technologies designed to address both informational and behavioral constraints to technical change are considered. First, we investigate the effectiveness of audiovisual messages (video) as a means of delivering information on input use and improved maize management practices to farmers. Second, we quantify the additional impact of complementing video with an interactive voice response (IVR) service. Third, we estimate the incremental effect of time‐sensitive short message services (SMS) messages designed to remind farmers about applying key practices at specific points during the season. We find that households that were shown a short video on how to become better maize farmers were performing significantly better on a knowledge test, more likely to apply recommended practices, and more likely to use fertilizer than households that did not view the video. These same households also reported maize yields about 10.5% higher than those that did not view the video. We find little evidence of an incremental effect of the IVR service or SMS reminders.
