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...

Xanthomonas Wilt of Banana (BXW) in Central Africa: Opportunities, challenges, and pathways for citizen science and ICT-based control and prevention strategies
Publication date: Available online 17 March 2018Source: NJAS - Wageningen Journal of Life SciencesAuthor(s): Mariette McCampbell, Marc Schut, Inge Van den Bergh, Boudy van Schagen, Bernard Vanlauwe, Guy Blomme, Svetlana Gaidashova, Emmanuel Njukwe, Cees LeeuwisAbstractXanthomonas Wilt of Banana (BXW) is a complex problem in the African Great Lakes Region that is affecting the livelihoods of millions of smallholder farmers. Since the first disease reports from Uganda and the Democratic Republic of Congo in 2001, BXW has been studied widely. The majority of these studies focus on the technological or biophysical dimensions, ...

Diagnosis of management of bacterial wilt and late blight in potato in Ethiopia: A systems thinking perspective
Publication date: Available online 29 March 2018Source: NJAS - Wageningen Journal of Life SciencesAuthor(s): E. Damtew, Shiferaw Tafesse, R. Lie, B. van Mierlo, B. Lemaga, K. Sharma, P.C. Struik, C. LeeuwisAbstractPotato is one of the most important food crops for smallholder farmers in the Ethiopian highlands. Diseases, particularly bacterial wilt (caused by Ralstonia solanacearum) and late blight (caused by Phytophthora infestans), are among the major constraints of potato production, despite continuous efforts to control them. Bacterial wilt and late blight are complex problems with multiple technical and institutional ...

Farmers’ knowledge and practices of potato disease management in Ethiopia
Publication date: Available online 30 March 2018Source: NJAS - Wageningen Journal of Life SciencesAuthor(s): Shiferaw Tafesse, E. Damtew, B. van Mierlo, R. Lie, B. Lemaga, K. Sharma, C. Leeuwis, P.C. StruikAbstractEffective management of potato diseases such as bacterial wilt and late blight depends to a large extent on farmers’ knowledge of the diseases as well as on the integration of recommended management methods in their daily practices. Late blight has continued to be a dominant potato disease for many decades in Ethiopia, whereas bacterial wilt has emerged more recently with a devastating impact on the country’s...

Farm diversity and resource use efficiency: Targeting agricultural policy interventions in East Africa farming systems
Publication date: April 2018Source: NJAS - Wageningen Journal of Life Sciences, Volume 85Author(s): Monica K. Kansiime, Piet van Asten, Koen SneyersAbstractThis 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) differen...

Scaling up of sweetpotato vine multiplication technologies in Phalombe and Chikwawa districts in Malawi: A gender analysis
Publication date: April 2018Source: NJAS - Wageningen Journal of Life Sciences, Volume 85Author(s): Netsayi N. Mudege, Robert O.M. Mwanga, Norita Mdege, Tafadzwa Chevo, Putri E. AbidinAbstractThis paper adopts a feminist approach to analyse how processes of scaling up of technologies to promote adoption can reinforce or reduce gender inequalities. It focuses on sweetpotato vine multiplication in Phalombe and Chikwawa districts in Malawi, and uses data from focus group discussions and individual interviews with men and women farmers and extension workers. Findings suggest that perception biases towards regarding the farmer ...

Recognizing farmers’ practices and constraints for intensifying rice production at Riparian Wetlands in Indonesia
Publication date: April 2018Source: NJAS - Wageningen Journal of Life Sciences, Volume 85Author(s): Benyamin Lakitan, Buyung Hadi, Siti Herlinda, Erna Siaga, Laily I. Widuri, Kartika Kartika, Lindi Lindiana, Yunin Yunindyawati, Mei MeihanaAbstractDespite 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. The techno...

Understanding the emergence of a hybrid knowledge production discourse: The case of the Generation Challenge Programme (GCP) drought tolerant rice research in India
Publication date: April 2018Source: NJAS - Wageningen Journal of Life Sciences, Volume 85Author(s): Soutrik Basu, Joost Jongerden, Guido RuivenkampAbstractThe Generation Challenge Programme (GCP) is an international platform for agrarian knowledge production for a complex scientific problem, namely, Drought. The GCP ushered in a new form of knowledge production that reconciles both the upstream laboratorial research and its downstream delivery at the farmer's field. This paper aims at understanding the knowledge production process of the GCP. More precisely, it explores the following three research questions: how three pro...

Understanding grower non-participation in the collective management of carob moth in pomegranate in Iran
Publication date: April 2018Source: NJAS - Wageningen Journal of Life Sciences, Volume 85Author(s): Naser Zamani, Khadijeh Bazrafkan, Kambiz MinaeiAbstractThe 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 collective act...

Currently, the region is experiencing a new-ICT revolution and there are high expectations of new-ICTs to enhance interaction and information exchange in extension service delivery. Using an innovation systems perspective, w...
