Item The influence of trust in the Nicaraguan Learning Alliance on capacity development of members and other influenced groups(Conference Paper, 2015-06-15) Landmann, Dirk H.; Cadilhon, Joseph J.Item Value Chain Development Wiki(Wiki, 2015) United States Agency for International DevelopmentItem Identification and analysis of smallholder producers’ constraints: Applications to Tanzania and Uganda(Journal Article, 2015-02-17) Baker, Derek; Cadilhon, Joseph J.; Ochola, W.This article puts forward a method for the analysis of constraints faced by developing countries’ smallholder producers. It is consistent with theories of constraints, efficient in terms of cost and researchers’ time, and accessible to a non-technical audience. A hybrid of workshop discussion and individual data collection, it also draws on data and analyses available in most developing countries. The article presents an application to smallholder livestock systems in Tanzania and Uganda, reporting results and analysis relating constraints to households’ characteristics and conditions, and their stated goals. While limitations are identified, it is proposed for application in other development fields.Item A rapid, quantitative assessment of household level food security: description of the data collection tool and the analysis(Working Paper, 2014-12-12) Wijk, Mark T. van; Ritzema, Randall S.; Valbuena, Diego; Douxchamps, Sabine; Frelat, RomainItem Impact evaluation of innovation platforms to increase dairy production: A case from Uttarakhand, northern India(Thesis, 2014-07-15) Subedi, S.Item The influence of trust in the Nicaraguan Learning Alliance on capacity development of members and other influenced groups(Thesis, 2015-02) Landmann, Dirk H.Item Impact of Innovation Platforms on Marketing Relationships: The Case of Volta Basin Integrated Crop-Livestock Value Chains in Ghana(Conference Paper, 2013) Adane-Mariami, Z.; Cadilhon, Joseph J.; Werthmann, C.Item Impact of Volta2 innovation platforms on improvement and increase of crop and livestock production in four villages of Yatenga province, Northern Burkina Faso(Conference Paper, 2013) Teno, G.; Cadilhon, Joseph J.; Some, Hubert W.Item Field testing a conceptual framework for innovation platform impact assessment: the case of MilkIT dairy platforms in Tanga region, Tanzania(Presentation, 2014) Pham Ngoc Diep; Cadilhon, Joseph J.; Maass, Brigitte L.Item Impact evaluation of innovation platforms to increase dairy production: A case from Uttarakhand, northern India(Presentation, 2014-08-15) Subedi, S.; Cadilhon, Joseph J.; Thanammal, R.; Teufel, NilsItem Impact of innovation platforms on marketing relationships:the case of Volta basin integrated crop-livestock value chains in northern Ghana(Thesis, 2013) Adane-Mariami, Z.A recent trend in scientific and agricultural development approaches show a shift from linear transfer of technology models towards system thinking to improve livelihoods resilience of smallholder agriculturalists in developing countries, and thus to achieve sustainable food security. One manifestation of such shifts is the recognition of agricultural innovations as multi-dimensional and co-evolutionary processes which integrates technological, organizational, socio-economic and institutional innovations that can create synergies when applied jointly. This thesis attempts to test a new conceptual framework for evaluating innovation platforms (IPs) for agri-food value chains. The framework is based on the structure-conduct-performance hypothesis of industrial organization in combination with concepts from new institutional economics and marketing. Data to test the framework was collected through interviews of stakeholders of two IPs in the Volta Basin Development Challenge Program on integrated management of rainwater in crop-livestock agro-ecosystems in two northern regions of Ghana. The study used a mixed methods research methodology. A semi-logarithmic multiple regression analysis was employed to test relationships between the variables representing the structure, conduct and performance of the platforms following a principal components factor analysis to obtain reduced number of underlying factors from Likert-type statements on communication and information sharing (representing the conduct element) and improved market access (for performance). The qualitative information obtained through focus group discussions, interviews of platform facilitators and key respondents, and participant observation of an IP meeting also validates a possible link between the structure of the platforms, the conducts of their members, and the resulting market performance through reducing transaction costs of search and information. The econometric results also support this claim. Improvement in interaction or communication within IP, gender, the location of the IP, and household wealth were found to have a significant effect on members’ access to market. Due to the short life of the project and the small number of people involved in the IPs, it is difficult to come to a strong conclusion on whether the framework is most appropriate for conducting an impact evaluation, or if at all, the results so far achieved are significantly associated to the intervention. This suggests the need for further work to refine and test the framework extensively through impact evaluation of completed projects or projects with relatively longer life; and also assess the overall impact of the IPs including environmental, social, and project sustainability. However, given the theoretical support from well-founded theories, the new framework could be used side by side with conventional methods of project evaluation to support existing approaches by producing complementary or supplementary results and help judge its suitability.Item Impact evaluation of an innovation platform on improvement of crop and livestock productions in four villages of Yatenga province, Northern Burkina Faso(Thesis, 2013-09-15) Teno, G.This study is linked to Volta2 project, launched in December 2010 for 3 years. Volta2 project has used innovation platforms as its principal development tool to achieve integrated management of rainwater for crop-livestock agroecosystems in 2 West African countries (Burkina Faso and Ghana). The aim of our study is to assess the impact of structure of innovation platform members, their conduct, and the consequence on the improvement of performance of crop and livestock production in four focal villages of Yatenga province, northern Burkina Faso (Ziga, Koura Bagre, Pogoro Silmimosse and Bogoya). The study was conducted from April to September 2013 with 2 months of field surveys between mid-May and mid-July 2013 in the four villages. This study was conducted through one approach borrowed from socio-economic theory: the model of “Structure – Conduct – Performance (SCP)”. The improvement in crop and livestock production was measured by asking farmers for their perception of this improvement. For data collection, focus group discussions and individual surveys with different stakeholders were used. Data analysis was carried through SPSS software, firstly for factor analysis to identify the dominant constructs of what makes innovation platform successful. And then, for regression analysis to determine the relationships between structure of innovation platform, the conduct of its members and whether they are achieving the objectives they set themselves in terms of improvement of crop and livestock production. Qualitative data was also interpreted to complete and interpret the results obtained through the analysis of quantitative data. Our study shows a positive impact of innovation platform, set up by Volta2 project, on IP member’s practices in Yatenga province. Innovation platform have contributed to the change of mentalities and conduct of its members in their activities. Indeed, through IP, its members have benefited from different support in their activities that have contributed to their capacity development, mainly by the reinforcement of their human and social capacity. The human capacity was improved through different trainings and advice received by IP members from different facilitators of innovation platform, such as training in animal and crop production, training in access to market, training in management of rainwater for crop and livestock production, etc. The social capacity of IP members was improved through new contacts and new partners that IP members have got in their activities. Indeed, through innovation platform, IP members of one village have entered in contact with IP members of other villages. Innovation platform have contributed to closer working relationships among IP members within the same village and to villagers gaining easier access to some organisations such as micro-credit organisations, animal husbandry and phytosanitary services of agricultural ministry, etc., which can help them to improve their activities. This improvement of human and social capacity of IP members has resulted in the improvement of crop and livestock production through a better exchange of information and knowledge between different stakeholders and a better access to different support services. Thus, our study shows a positive impact of innovation platform set up by Volta2 project for improvement of crop and livestock production in Yatenga province. These findings justify the necessity to support this kind of project in the perspective of reinforcing food security and reducing poverty in rural areas around the world.Item VAIMS methodological package(Report, 2009) Baker, Derek; Rich, Karl M.; Spies, D.; Taljaard, P.; Jooste, A.; Hoffman, L.; Laubscher, K.Item Questionnaires et données pour la validation empirique d'une approche conceptuelle pour évaluer l'impact des plateformes d'innovation sur le développement de chaînes de valeur agro-alimentaires au Ghana et au Burkina Faso(Dataset, 2013-09-11) Cadilhon, Joseph J.; Teno, G.; Adane-Mariami, Z.Item Questionnaires and data for the empirical testing of a conceptual framework to evaluate the impact of innovation platforms on agrifood value chains development in Ghana and Burkina Faso(Dataset, 2013-09-11) Cadilhon, Joseph J.; Adane-Mariami, Z.; Teno, G.Item ODK - A premier sampling support tool(Poster, 2013-06-28) Kihara, Absolomon; Kemp, Stephen J.Item Typical patterns of smallholder vulnerability to weather extremes with regard to food security in the Peruvian Altiplano(Journal Article, 2012-09) Sietz, D.; Mamani Choque, S.E.; Ludeke, M.K.B.Smallholder livelihoods in the Peruvian Altiplano are frequently threatened by weather extremes, including droughts, frosts and heavy rainfall. Given the persistence of significant undernourishment despite regional development efforts, we propose a cluster approach to evaluate smallholders’ vulnerability to weather extremes with regard to food security. We applied this approach to 268 smallholder households using information from two existing regional assessments and from our own household survey. The cluster analysis revealed four vulnerability patterns that depict typical combinations of household attributes, including their harvest failure risk, agricultural resources, education level and non-agricultural income. We validated the identified vulnerability patterns by demonstrating the correlation between them and an independently reported damage: the purchase of food and fodder resulting from exposure to weather extremes. The vulnerability patterns were then ranked according to the different amounts of purchase. A second validation aspect accounted for independently reported mechanisms explaining smallholders’ sensitivity and adaptive capacity. Based on the similarities among the households, our study contributes to the understanding of vulnerability beyond individual cases. In particular, the validation strengthens the credibility and suitability of our findings for decision-making pertaining to the reduction of vulnerability.Item Circles of association: The connections of community-based food systems(Journal Article, 2007-06-25) Conner, D.S.; Levine, R.Item Survey instruments tool(2012) International Institute for Environment and Development; OxfamItem Livestock data innovation project: Constraint analysis workshops wiki(2012) Livestock Data Innovation in Africa Project
