Publication date: Available online 24 May 2018 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Benyamin Lakitan, Buyung Hadi, Siti Herlinda, Erna Siaga, Laily I. Widuri, Kartika Kartika, Lindi Lindiana, Yunin Yunindyawati, Mei Meihana Despite its large acreage, riparian wetland has been underutilized in Indonesia. Intensity of agricultural activities on this wetland was very low mainly due to two unfavorable extremes, i.e. unpredictable occurrence of flooding during rainy season and drought during dry season. Relevant, affordable, and acceptable technologies are required as solution to this problems...

Understanding grower non-participation in the collective management of carob moth in pomegranate in Iran
Publication date: Available online 15 December 2017 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Naser Zamani, Khadijeh Bazrafkan, Kambiz Minaei The management of carob moth is a complex and multidimensional process that is only possible when collective action takes place in the pest-affected areas. The non-participation in carob moth management has led to increasing pest problems which unless managed collectively, they impose a serious limitation on pomegranate production and endanger the future of pomegranate orchards in Arsanjan county, Fars province, Iran. The current study aimed to explore why col...

Farm diversity and resource use efficiency: Targeting agricultural policy interventions in East Africa farming systems
Publication date: Available online 11 December 2017 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Monica K. Kansiime, Piet van Asten, Koen Sneyers This paper aimed to provide empirical evidence on the links between farm diversity and resource use efficiency. Using farm typology and stochastic production frontier approaches, we grouped households into those pursuing similar livelihood strategies and assessed their resource use efficiency. At 60% coefficient of similarity, we identified three distinct farm types – Farm-specialised, Diversified and Off-farm specialised. Significant (p<0.01) differ...

Institutional diagnostics for African food security: Approaches, methods and implications
This article introduces a special issue that investigates approaches and methods, anchored in different institutionalisms, diagnosing how institutions influence food security levels in diverse African contexts. We draw two main lessons from this special issue. Firstly, there is a clear need for localized ex-ante institutional diagnostics to understand developments in food security in Africa. This can inform and guide decision-makers in designing locally appropriate interventions. Secondly, developing institutional diagnostics in view of sustainable food security requires theoretical triangulation; food insecurity is typica...

An institutional diagnostics of agricultural innovation; public-private partnerships and smallholder production in Uganda
Publication date: Available online 1 November 2017 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Diana Akullo, Harro Maat, Arjen E.J. Wals This paper presents and discusses a diagnostic framework to identify institutional processes in the creation of public-private partnerships (PPPs) for agricultural innovation. The diagnostic framework proposed here combines a conceptualisation of institutions with a conceptualisation of technology. We argue that a performative notion of institutions provides a better tool for institutional diagnostics than the common understanding of institutions as ‘rules of the g...

Diagnosing institutional logics in partnerships and how they evolve through institutional bricolage: Insights from soybean and cassava value chains in Ghana
This article proposes institutional logics as a theory and methodology for institutional diagnosis to gain insight into context-embedded negotiation and change processes created by project-based partnership interventions. We analyse the institutional logics of organisations active in the development of two value chains in Ghana to subsequently show how, in partnerships, these logics are negotiated in light of the objectives and interests of the intervention. The main findings are that donors, with their market and professionalisation logics, are quite influential, but many other development actors still adhere to principle...

Diagnostics and field experiments
Publication date: Available online 6 November 2017 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Maarten Voors Field experiments have been embraced in development economics and political science as a core method to learn what development interventions work and why. Scientists across the globe actively engage with development practitioners to evaluate projects and programmes. However, even though field experiments have raised the bar on causality, they are often too narrowly defined and lack focus on structural development problems. Researchers and development practitioners should do more to improve the di...

Identifying ripple effects from new market institutions to household rules -Malawi ’s Agricultural Commodity Exchange
Publication date: Available online 11 November 2017 Source:NJAS - Wageningen Journal of Life Sciences Author(s): Georgina Gomez, Saskia Vossenberg The introduction of new rules in an institutional field provides agents with a new set of opportunities and constraints on which they can leverage to change the rules in other institutional fields. Inspired by Elinor Ostrom, we term this causality a ripple effect, born out of the initial institutional changes. In this article we enquired in what ways women farmers could transfer genderblind changes in the market to the household. We developed a diagnostic tool to capture thi...
