Knowledge for a sustainable world

BSc, MSc, PhD

Jonne Rodenburg joined the University of Greenwich in January 2018, after a 13-years tenure at the CGIAR Africa Rice Center (AfricaRice).

Jonne obtained an MSc-degree from Wageningen University (WU) in 1999. His MSc research project focused on the effects of slash-and-burn agriculture on spatial variation in soil fertility in rubber-rice agroforests in Indonesia, in collaboration with the World Agroforestry Centre (ICRAF). In 2005 he obtained a PhD-degree from the same university. His PhD research was on defense mechanisms (resistance and tolerance) in sorghum against the parasitic weed Striga hermonthica. Fieldwork for this study was conducted in Mali, at the experimental farm of ICRISAT. Prior to obtaining his PhD-degree, Jonne started as agronomist at AfricaRice. He was first based in Mali (2004-2005) and then moved to Benin (2005-2007), Senegal (2007-2009) and Tanzania (2009-2016). His last home base was in Côte d’Ivoire (2016-2017). At AfricaRice his work focused mainly on weed problems, with a special interest in parasitic weeds (Striga asiatica, S. hermonthica, Rhamphicarpa fistulosa) in rain-fed rice systems. Together with his co-workers and students he identified suitable rice varieties and agronomic management practices for the control of these pests. He also worked on bird - weed interactions, mechanical weed control, Good Agricultural Practices and the System of Rice Intensification in irrigated rice systems and Conservation Agriculture practices in rain-fed uplands. The prime aim of all of his research was to develop feasible and effective practices for smallholder rice farmers to raise their productivity and input-use efficiency in a sustainable and cost-effective manner.

Jonne Rodenburg’s main focus is on understanding the ecology and biology of the parasitic weeds Striga (S. asiatica and S. hermonthica) and Rhamphicarpa fistulosa in rain-fed cropping systems and to use these insights to develop sustainable management practices that are feasible for smallholder farmers. This includes the identification of genetic resistance and tolerance in cereal germplasm and studying specificity of these defense mechanisms across ecotypes differing in virulence levels.

Jonne is also keen on elucidating the principles and mechanisms behind effective control strategies. Recently he identified, with co-workers, combinations of leguminous cover crops, zero-tillage and crop-residue mulching that effectively reduced Striga asiatica infections and seed bank increments in a rice-maize rotation system. His work now continues to unravel what components contribute to this control and how. Another example concerns the relation between soil fertility and parasitic weeds. Striga and low soil fertility are frequently mentioned as associated crop production constraints in Africa. Despite numerous studies, the universality and causality of this association lacks conclusive evidence and the translation into reliably effective and feasible control practices for smallholder farmers has so far attained little tangible success. Jonne is keen on deepening the understanding and practical implications of this relation.

A second key interest of Jonne concerns the sustainable intensification and diversification strategies for smallholder farmers in inland valleys in Africa. He is keen on understanding how crop production in these environments can be optimized by improved planning in space and time as well as in terms of crop species choices and combinations thereof. Indicators for such optimization would not be restricted to crop performance in terms of productivity alone, but also to resource-use efficiency, pest (including weeds) and disease management, and natural resources/ecosystem services provided by the inland valley environment.

At the University of Greenwich he will coordinate the MSc course Sustainable Agriculture and teach on Weeds and Weed Management. Jonne currently supervises three PhD students:
