A widely applied food safety management system is the Hazard Analysis and Critical Control Points (HACCP) system, which has become mandatory in many countries and is therefore of major relevance for food producers, processors and traders worldwide. However, mandatory HACCP implementation may act as a trade barrier for many developing and transition countries and pose particular difficulties for small food producers and processors. In this paper, we evaluate the current state of knowledge and implementation of HACCP-based management systems among small-scale honey producers in Brazil. The empirical analysis is based on original survey data collected from a random sample of 115 households involved in apiculture in the northeast of Brazil. In the interviews, beekeepers were asked about their knowledge of HACCP requirements and the implementation of these requirements. Based on a principal component analysis, we create knowledge and implementation indices and compare these indices to relevant household characteristics and honey production conditions. Both the knowledge of requirements and the implementation of these requirements are strongly linked to the households' connectedness along the value chain and their access to a suitable honey extraction facility. In order to enhance the competitiveness of the Brazilian small-scale honey sector, policy-makers should foster cooperation among producers and improve their connectedness to input and output markets. Furthermore, access to appropriate honey extraction facilities should be improved."],["dc.identifier.doi","10.3920/jcns2012.x003"],["dc.identifier.gro","3148890"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5527"],["dc.language.iso","en"],["dc.notes.intern","Wollni Crossref Import"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1569-1829"],["dc.title","Knowledge and implementation of HACCP-based management systems among small-scale honey producers in Brazil"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]Details DOI2020Journal Article Research Paper [["dc.bibliographiccitation.artnumber","jby049"],["dc.bibliographiccitation.firstpage","1"],["dc.bibliographiccitation.journal","European Review of Agricultural Economics"],["dc.bibliographiccitation.lastpage","24"],["dc.contributor.author","Ogutu, Sylvester Ochieng"],["dc.contributor.author","Fongar, Andrea"],["dc.contributor.author","Gödecke, Theda"],["dc.contributor.author","Jäckering, Lisa"],["dc.contributor.author","Mwololo, Henry"],["dc.contributor.author","Njuguna, Michael"],["dc.contributor.author","Wollni, Meike"],["dc.contributor.author","Qaim, Matin"],["dc.date.accessioned","2019-07-31T09:50:27Z"],["dc.date.available","2019-07-31T09:50:27Z"],["dc.date.issued","2020"],["dc.description.abstract","We analyse how agricultural extension can be made more effective in terms of increasing farmers’ adoption of pro-nutrition technologies, such as biofortified crops.

The first instrument is an information campaign on tree planting in oil palm. The second instrument combines the information campaign with a structural intervention that provides native tree seedlings for free. We implemented a randomized controlled trial in oil palm growing villages in Jambi, Indonesia. Our study addresses the underlying mechanisms of behavioral change, by investigating how the policy instruments shape farmers’ perceptions, intentions and actual adoption decisions. The results show that information campaigns and structural interventions can motivate tree planting among smallholder oil palm farmers in Indonesia. While both treatments have a positive and significant effect, the intervention combining information with seedling provision leads to significantly higher adoption rates, indicating that overcoming structural barriers is critical. While changes in perceptions and intentions fully mediate the effect of the information campaign on adoption, they can only partially explain the effect of the combined intervention. Thus, to promote a transition towards more sustainable development pathways, facilitating easy access to critical inputs may be key to motivate adoption among large numbers of potential users."],["dc.format.extent","28"],["dc.identifier.ppn","106777694X"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/108106"],["dc.language.iso","en"],["dc.publisher","SFB 990, University of Göttingen; GOEDOC, Dokumenten- und Publikationsserver der Georg-August-Universität Göttingen"],["dc.publisher.place","Göttingen"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | C | C08: Design effektiver Politikinstrumente zur Förderung nachhaltiger Landnutzung"],["dc.relation.crisseries","EFForTS Discussion Paper Series"],["dc.relation.orgunit","Johann-Friedrich-Blumenbach-Institut für Zoologie und Anthropologie"],["dc.rights","CC BY-NC-ND 4.0"],["dc.subject.gro","tree-planting; oil palm; intentions; mediation; Asia"],["dc.subject.gro","sfb990_discussionpaperseries"],["dc.title","Promoting sustainable land use choices in Indonesia"],["dc.title.subtitle","experimental evidence on the role of changing mindsets and structural barriers"],["dc.type","working_paper"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details2019Journal Article [["dc.bibliographiccitation.firstpage","657"],["dc.bibliographiccitation.issue","5"],["dc.bibliographiccitation.journal","Agricultural Economics"],["dc.bibliographiccitation.lastpage","672"],["dc.bibliographiccitation.volume","50"],["dc.contributor.author","Jäckering, Lisa"],["dc.contributor.author","Gödecke, Theda"],["dc.contributor.author","Wollni, Meike"],["dc.date.accessioned","2019-12-04T11:43:12Z"],["dc.date.accessioned","2021-10-27T13:20:10Z"],["dc.date.available","2019-12-04T11:43:12Z"],["dc.date.available","2021-10-27T13:20:10Z"],["dc.date.issued","2019"],["dc.description.abstract","To date, little is known about how information flows within farmer groups and how extension interventions could be designed to deliver combined information on agriculture and nutrition. This study uses unique network data from 815 farm households in Kenya to investigate the structure and characteristics of agricultural and nutrition information networks within farmer groups. Dyadic regressions are used to analyze the factors influencing link formation for the exchange of agricultural and nutrition information. In addition, we apply fixed‐effects models to identify the characteristics of central persons driving information exchange in the two networks, as well as potentially isolated persons, who are excluded from information networks within their farmer groups. Our results show that nutrition information is exchanged within farmer groups, although to a limited extent, and mostly flows through the existing agricultural information links. Thus, diffusing nutrition information through agricultural extension systems may be a viable approach. Our findings further suggest that group leaders and persons living in central locations are important drivers in the diffusion of information in both networks and may thus serve as suitable entry points for nutrition‐sensitive extension programs. However, we also identify important heterogeneities in network characteristics. In particular, nutrition information is less often exchanged between men and women, and some group members are completely isolated from nutrition information exchange within their farmer groups. We derive recommendations on taking these differences in network structure and characteristics into account when designing nutrition‐sensitive extension programs."],["dc.identifier.doi","10.1111/agec.12516"],["dc.identifier.eissn","1574-0862"],["dc.identifier.issn","0169-5150"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16836"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/91944"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.relation.eissn","1574-0862"],["dc.relation.issn","1574-0862"],["dc.relation.issn","0169-5150"],["dc.relation.orgunit","Fakultät für Agrarwissenschaften"],["dc.rights","CC BY 4.0"],["dc.rights.access","openAccess"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject","Africa; communication networks; dyadic regressions; farmer groups; Kenya; nutrition-sensitive agriculture"],["dc.subject.ddc","630"],["dc.title","Agriculture–nutrition linkages in farmers’ communication networks"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI2021Journal Article [["dc.bibliographiccitation.firstpage","106524"],["dc.bibliographiccitation.journal","Agricultural Water Management"],["dc.bibliographiccitation.volume","243"],["dc.contributor.author","Castillo, Gracia Maria Lanza"],["dc.contributor.author","Engler, Alejandra"],["dc.contributor.author","Wollni, Meike"],["dc.date.accessioned","2021-04-14T08:30:35Z"],["dc.date.available","2021-04-14T08:30:35Z"],["dc.date.issued","2021"],["dc.identifier.doi","10.1016/j.agwat.2020.106524"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/83299"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.relation.issn","0378-3774"],["dc.title","Planned behavior and social capital: Understanding farmers’ behavior toward pressurized irrigation technologies"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]Details DOI2013-09Working Paper [["dc.bibliographiccitation.seriesnr","1"],["dc.contributor.author","Faust, H."],["dc.contributor.author","Schwarze, S."],["dc.contributor.author","Beckert, B."],["dc.contributor.author","Bruemmer, B."],["dc.contributor.author","Dittrich, C."],["dc.contributor.author","Euler, M."],["dc.contributor.author","Gatto, M."],["dc.contributor.author","Hauser-Schäublin, B."],["dc.contributor.author","Hein, J."],["dc.contributor.author","Holtkamp, A.

One possible reaction was moving to specialty markets, where price pressure was perceived to be lower. We use original survey data from 2002/2003 and 2003/2004 to analyze the factors influencing participation in specialty markets and to estimate separate production functions for specialty and conventional coffee farmers allowing for farm-specific inefficiencies. Applying a sample selection framework, we find significant selection bias in the sub-sample of specialty farmers and evidence for the overestimation of efficiency, if this bias is not adequately controlled for. Among the most important factors that influence farm-specific efficiency levels in the two sub-samples are the availability of additional income activities, experience in coffee cultivation, and membership in cooperatives. Based on the results, we derive policy recommendations to improve farmers’ production performance and ability to cope with the effects of the coffee crisis. These policy measures include the provision of extension services with respect to farm management skills, the creation of income opportunities in rural areas, and the support of farmer-owned cooperatives. Highlights: ► We estimate production frontiers for specialty and conventional coffee farmers. ► Models control for selection bias and analyze farm-specific inefficiency effects. ► Average efficiency is overestimated if selection bias is not adequately controlled. ► Farm-level efficiency determinants are consistent across models. ► Determinants include experience, cooperative membership and off-farm activities."],["dc.identifier.doi","10.1016/j.foodpol.2011.11.004"],["dc.identifier.gro","3148885"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5522"],["dc.language.iso","en"],["dc.notes.intern","Wollni Crossref Import"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","0306-9192"],["dc.title","Productive efficiency of specialty and conventional coffee farmers in Costa Rica: Accounting for technological heterogeneity and self-selection"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]Details DOI2020Journal Article Research Paper [["dc.bibliographiccitation.firstpage","10402"],["dc.bibliographiccitation.issue","24"],["dc.bibliographiccitation.journal","Sustainability"],["dc.bibliographiccitation.volume","12"],["dc.contributor.author","Bettin, Johannes"],["dc.contributor.author","Wollni, Meike"],["dc.date.accessioned","2021-04-14T08:32:33Z"],["dc.date.available","2021-04-14T08:32:33Z"],["dc.date.issued","2020"],["dc.identifier.doi","10.3390/su122410402"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/17705"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/83946"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.notes.intern","Merged from goescholar"],["dc.publisher","MDPI"],["dc.relation.eissn","2071-1050"],["dc.rights","CC BY 4.0"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0/"],["dc.title","Environmental Concern and Urbanization in India: Towards Psychological Complexity"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI2015-08Working Paper [["dc.bibliographiccitation.seriesnr","18"],["dc.contributor.author","Vorlaufer, Miriam"],["dc.contributor.author","Ibanez, Marcela"],["dc.contributor.author","Juanda, Bambang"],["dc.contributor.author","Wollni, Meike"],["dc.date.accessioned","2022-05-19T10:11:15Z"],["dc.date.available","2022-05-19T10:11:15Z"],["dc.date.issued","2015-08"],["dc.description.abstract","This paper investigates the trade-off between conservation and equity considerations in the use of payments for environmental services (PES) that implicitly incorporate different distributive justice principles.
