This study identifies and describes 1) the benefits of collective action and 2) how smallholder rice farmers act collectively within a group and why. This paper presents a case study involving smallholder rice farmers in Yogyakarta, Indonesia, who have worked collectively and benefited from the valuechain transformation. Data were sourced from semi-structured interviews involving relevant actors. This interview data is complemented with document studies. The finding shows that collective action helps build competitive advantage by facilitating smallholder farmers to develop their capabilities, improve their bargaining power, and bypass intermediaries. Nevertheless, this only works for smallholder farmers with a production capacity above their household needs. The findings also show that the drivers of collective action are motivation, trust, shared visions, social cohesion, good leadership, active engagement, and external support. This study contributes to knowledge about the interaction between actors within a collective group and how to develop smallholder organizations, particularly for rice commodities.</p></div>","PeriodicalId":43876,"journal":{"name":"Journal of Co-operative Organization and Management","volume":"12 1","pages":"Article 100236"},"PeriodicalIF":2.1,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140621999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, there is a lack of understanding how an entrepreneurial orientation (EO) helps them to perform in competition. This study theoretically and empirically examines whether cooperatives benefit from EO in their multi-dimensional goal system. Additionally, the study asks how cooperative-specific collective characteristics relate to EO and performance. Using cross-sectoral data of 368 cooperatives in Switzerland and applying structural equation modelling (PLS), the results show that EO is significantly and positively linked to economic performance. Inter- and intraorganizational cooperation is associated with higher levels of EO and indirectly affects performance through EO.

Using a systematic literature review approach, the article relied on desk research from relevant secondary sources. Past and current data on the GAPAs’ development were analyzed to present trends. While various forms of traditional cooperation in the agriculture sector exist in Sudan, the first formal attempt to establish cooperatives was undertaken in the 1920s. The development of the cooperative movement was strongly influenced by changing governmental policies during the different governmental eras. Political intervention, lack of finance, poor infrastructure and limited capacity of cooperative members and managers were major constraints that hindered the cooperative movement. GAPAs were first established in 1992 in North Kordofan State, and the model was scaled up in 2005 to the whole country. The main objective of GAPAs is to increase the production of gum Arabic, for example by reducing the members’ dependency on the traditional finance (<em>Shail</em>) system. However, GAPAs have faced the same constraints that also hindered other types of agricultural cooperatives. The government’s focus on primarily increasing the number of GAPAs and size of membership rather than improving their organizational capacity and quality of services to members has largely rendered the GAPAs ineffective. Therefore, the study recommends raising awareness among policymakers in Sudan for the problems GAPAs and other agricultural cooperatives currently face, as well as of local communities working in agriculture for the antecedents and benefits of collective action, which remains an urgent priority.</p></div>","PeriodicalId":43876,"journal":{"name":"Journal of Co-operative Organization and Management","volume":"12 1","pages":"Article 100217"},"PeriodicalIF":2.1,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139028953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Perceived openness is examined from two distinct perspectives, that is, awareness of right of involvement as owners (which in this paper we equated with co-operative member ownership structure) and possibility of involvement or perception of organisation openness (which in this paper we equated with co-operative process). It was found in the multivariate Logistic model that possibility rather than right of involvement is related to member openness. This suggests that the process of co-operation in a co-operative plays a greater role than the organisational structure of that co-operative in facilitating member input. This is a significant finding and suggests that greater attention needs to be given to process and openness in co-operative research and practice. It also suggests that co-operatives cannot just draw on their member ownership structure, in building member engagement at time of crisis.</p></div>","PeriodicalId":43876,"journal":{"name":"Journal of Co-operative Organization and Management","volume":"11 2","pages":"Article 100218"},"PeriodicalIF":2.1,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49722928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
