29 pages, Agent-based models are important tools for simulating farmers’ behaviour in response to changing environmental, economic or institutional conditions and policies. This article introduces an agent-based modelling approach that combines behavioural factors with standard bio-economic modelling of agricultural production. More specifically, our framework integrates the cumulative prospect theory and social interactions with constrained optimisation decisions in agricultural production. We apply our modelling approach to an exemplary bio-economic model on the assessment of weed control decisions. Results show the effects of heterogeneous farm decision-making and social networks on mechanical weed control and herbicide use. This framework provides a generic and conceptually sound approach to improve the scope for representing farmers’ decision-making and allows the simulation of their decisions and recent advances in behavioural economics to be aligned with existing bio-economic models of agricultural systems.
11pgs, Taylor and Francis Online, The field of research on agricultural and rural extension and education, also referred to as advisory services and intermediaries, has always engaged with different aspects of the spaces in which agricultural producers (farmers, growers, ranchers) are situated and operate. In this editorial, I will reflect on the elements and environments which jointly constitute and shape the farm (Darnhofer 2020) and their connection with extension and advisory services in the digital age, opening up new digital and virtual spaces. Extension and advisory services receive ample consideration in current debates on digitalization and digital transformation of the agrifood sector, and are an important focus of attention for agriculture and food systems research, practice and policy (Ehlers, Huber, and Finger 2021; Ingram and Maye 2020; Klerkx 2020). In what follows, I will elaborate on some digital and virtual spaces as sites of extension and advisory services research, to progress the field of study for which The Journal of Agricultural Education and Extension serves as a publication outlet.
21 pages, Multiple dynamics jointly determine who we befriend, however, researchers have failed to systematically assess which processes matter most under different circumstances. Here I draw on observations around how the demands of paddy rice cultivation shape social interaction to demonstrate that the relative importance of reciprocity, transitivity and generalised exchange to who rice producers choose as friends varies with the amount of agricultural land under their control. In doing so, I use unique data on farm size and friendship amongst 4713 rice-growing smallholders in 162 rural villages in Jiangxi, China along with a new technique for measuring the relative importance of effects in Stochastic Actor-Oriented Models. In line with the micro-level component of the recently advanced “theory of network ecology”, results suggest that features of an individual’s proximal environment can powerfully moderate the relative expression of network-formation mechanisms such that for some individuals, a dynamic may be expected to hold substantial sway over the process of choosing social contacts and, for others, no sway at all.
17 pages., via online journal article, The Sustainable Forestry and African American Land Retention
Program (SFLR) was launched in 2012 to increase adoption of sustainable forestry practices among African American landowners in
the southeastern United States to prevent land loss, increase forest
health, and build economic assets. One of its main goals was to
build communication networks through which African American
landowners could obtain and share information about forestry practices and landowner assistance programs independent of public agencies. To measure and examine the growth of these communication
networks over a three-year period (2014-2017), we conducted 87
interviews with landowners (24 of whom were interviewed multiple
times), SFLR personnel, and Federal and State staff members in
North Carolina. We used complementary methods of data gathering
and analysis, including social network analysis and qualitative analysis. Our results showed expanding communication networks will be
sustained independently of the program over time, although there is
still a heavy reliance on program personnel.
13 pages., Via online journal., Access to food is a basic pillar of human development. It is therefore unsurprising that it features so centrally on global development agendas and that a robust, interdisciplinary literature seeks to examine its determinants. This study focuses on the relationship between mobile technology and food access. Specifically, we ask whether mobile technology can strengthen the relationship between food access and certain social and political factors such as remittance flows and political participation. We use Afrobarometer surveys and highly disaggregated data on 2G network coverage to estimate a multilevel model testing how increased connectivity measured by mobile technology influences food access. We show that mobile phone use and higher frequency of use are significantly and positively correlated with food access, but we do not find evidence that remittances and political participation levels can explain the mechanisms linking mobile technology and food access. The study highlights that connectivity can play a powerful role in shaping food outcomes even when controlling for commonly identified impediments such as income constraints or physical isolation. These findings suggest that policies aimed at improving food access should devote attention to strengthening both communication and physical infrastructure.

19 pages., via online journal., Agricultural e‐commerce clusters are new phenomena that have emerged in rural China. In examining the case of Shuyang County in Jiangsu Province, this paper puts forward an integrated model revealing the formation mechanism of agricultural e‐commerce clusters. The paper shows that the formation of agricultural e‐commerce clusters involves four processes of technology introduction, technology diffusion, quality crisis, and industrial agglomeration based on elements such as industry bases, e‐commerce platforms, network facilities, logistics services, entrepreneurial talent, local government, and market demand. Rural social networks and imitation behaviors promote technology diffusion by reducing the cost of technology introduction, and industrial agglomeration is found in the economies showing a deepening of labor divisions and geographic agglomeration. Throughout the formation process, a quality crisis may occur due to a race to the bottom and the opportunistic behaviors of local farmers. This work suggests that regional e‐commerce development is a systematic project. Governments of developing countries should not only realize the positive impacts of e‐commerce for the development of the agricultural industry but also recognize the premise and logic of how e‐commerce can play a prominent role.
