“…Extensions of binary variable models, such as multivariable probit/logit and multinomial logit, are used to capture the adoption complementarities between multiple technologies (Kassie et al 2015;Wainaina et al 2016). Duration models are used, although rarely, to capture the temporal dimension of adoption (Matuschke and Qaim 2008;Ofori et al 2020). Irrespective of the model selection, when an adoption study frames its research questions in order to fit the available econometric framework, most of the contextual information is lost in the process, and the study fails to contribute effectively toward policy development.…”

This paper reviews the empirical literature on the determinants of farmer adoption of sustainable intensification technologies in maize agri-food systems of the Global South. The attributes of the technology and the dissemination institutions interact with farm/farmer-specific variables, leading to heterogeneous impacts, making the prediction of technology adoption challenging. However, most empirical studies oversimplify the adoption process and examine only the farm/farmer-specific variables as the determinants of adoption, thereby limiting the scope of learning on how the attributes of the technology and the dissemination system could have been altered to realize a more efficient and more inclusive technological change. We argue for a realignment of empirical adoption analysis for better implications through a conscious rejection of the assumption that the onus of technology performance rests solely with the farmer. Here we review the studies published between 2007 and 2018 on the adoption of sustainable intensification technologies in maize systems of the Global South to examine how the adoption models are currently dependent on the farm/farmer attributes vis-à-vis the attributes of technologies and disseminating institutions. The main findings from a synthesis of 137 adoption studies are threefold. (1) Limited information access and technologies not suitable for the small landholdings were the major constraints of farmer adoption of technologies. (2) The criticisms on the conventional adoption analysis concerning oversimplification and decontextualization of the decision-making process are reaffirmed. (3) The empirical adoption research needs to incorporate the attributes of technologies and the socio-institutional context to develop better research strategies toward inclusive agrarian development. We examine how the framework of the socioeconomic analysis can be reconstructed to facilitate the research and development (R&D) institutions to overcome the major hurdles of rapid and inclusive dissemination. Evaluation of the degree to which the attributes of technology favor its adoption requires increased research attention.

“…A broad literature review investigated the barriers to adoption, including farm(er) characteristics, such as a lack of knowledge and/or financial means, incompatible equipment or small plot sizes that reduce the financial attractiveness of the technology for the farmers [13,14]. Nonetheless, apart from studies on precision farming in the United States of America [15][16][17][18][19][20][21][22][23][24], there is only little evidence for the barriers and drivers of the adoption of precision farming technologies in Europe. The few studies that are available are using observations from Germany and Denmark [11,12,[25][26][27], the Netherlands, France, Switzerland, Italy [28,29] and Hungary [30].…”

Drivers and Barriers Influencing the Willingness to Adopt Technologies for Variable Rate Application of Fertiliser in Lower Austria

et al. 2021

Even though a broad range of technologies for variable rate application of nitrogen fertiliser is available, there are hardly any documented cases of their use in Austria. In this study, the drivers and barriers of adoption have been investigated. A survey of 242 farmers in Lower Austria was conducted. The survey covered the farmers’ economic situation, concerns, and expectations regarding the future of their farms and their interest in precision farming technologies. A choice experiment was included in the survey to elicit farmers’ preferences for different features of variable rate application technologies. A series of multinomial logit, mixed logit and latent class logit models were run to analyze the choice experiment. Most farmers were interested in variable rate application, whereas technology costs, yield and environmental improvements were found to be important drivers of adoption. Also, farm size, farming system, technological level and network activities seem to play an important role in the uptake of variable rate application technologies.

“…We employed survival or duration models, which originated in the field of medicine for analyzing the survival of patients after specific diseases and treatments (Kaplan and Meier 1958 ) and were later used in other disciplines, such as agricultural economics, to study the adoption of agricultural innovations, such as improved varieties (Fuglie and Kascak 2001 ; Burton et al 2003 ; Dadi et al 2004 ; Matuschke and Qaim 2009 ; Alcon et al 2011 ; Oostendorp and Zaal 2012 ; Beyene and Kassie 2015 ; Nazli and Smale 2016 ; Ray and Maredia 2016 ; Lemessa et al 2019 ; Ofori et al 2020 ).…”

Dynamic guardianship of potato landraces by Andean communities and the genebank of the International Potato Center

et al. 2021

Background Potato landraces (Solanum spp.) are not only crucial for food security and sustenance in Andean communities but are also deeply rooted in the local culture. The crop originated in the Andes, and while a great diversity of potato persists, some landraces have been lost. Local communities and the genebank of the International Potato Center (CIP) partnered to re-establish some of these landraces in situ by supplying clean seed potatoes to farmers. Over time, the genebank formalized a repatriation program of potato landraces. Repatriation is the process of returning native germplasm back to its place of origin, allowing a dynamic exchange between ex situ and in situ conditions. So far, no comprehensive description of CIP’s repatriation program, the changes it induced, nor its benefits, has been carried out. Methods We addressed this research gap by analyzing CIP genebank distribution data for repatriated accessions, conducting structured interviews with experts of the repatriation program, and applying duration and benefit analyses to a survey dataset of 301 households. Results Between 1997 and 2020, 14,950 samples, representing 1519 accessions, were distributed to 135 communities in Peru. While most households (56%) abandoned the repatriated material by the fourth year after receiving it, the in situ survival probability of the remaining material stabilized between 36% in year 5 and 18% in year 15. Households where the plot manager was over 60 years old were more likely to grow the repatriated landraces for longer periods of times. While male plot management decreased survival times compared to female plot management, higher levels of education, labor force, wealth, food insecurity, and geographic location in the southern part of Peru were associated with greater survival times. Most farmers reported nutritional and cultural benefits as reasons for maintaining landrace material. Repatriated potatoes enabled farmers to conserve potato diversity, and hence, re-establish and broaden culinary diversity and traditions. Conclusions Our study is the first to apply an economic model to analyze the duration of in situ landrace cultivation by custodian farmers. We provide an evidence base that describes the vast scope of the program and its benefits.
