Muchunguzi, P.Asten, Piet J.A. vanVanlauwe, BernardBlomme, Guy[Overcoming challenges for crops, people and policies in Central Africa. The story of CIALCA stakeholder engagement.]Overcoming challenges for crops, people and policies in Central Africa. The story of CIALCA stakeholder engagement.

Trade-off analysis has become an increasingly important approach for evaluating system level outcomes of agricultural production and for prioritising and targeting management interventions in multi-functional agricultural landscapes. We review the strengths and weakness of different techniques av...


Wijk, Mark T. vanKlapwijk, C.J.Rosenstock, Todd S.Asten, Piet J.A. vanThornton, Philip K.Giller, Ken E.[Methods for environment: productivity trade-off analysis in agricultural systems]Methods for environment: productivity trade-off analysis in agricultural systems

Cassava production in Uganda and western Kenya has been hit hard by the cassava mosaic disease (CMD) epidemic. In response, CMD resistant cassava varieties are currently released on a wide scale. The new varieties yield up to 3 times more than the local varieties. These high yield levels will put...


Fermont, A.M.Obiero, H.M.Asten, Piet J.A. vanBaguma, Yona K.Okwuosa, E.[Improved cassava varieties increase the risk of soil nutrient mining: an exante analysis for western Kenya and Uganda]Improved cassava varieties increase the risk of soil nutrient mining: an exante analysis for western Kenya and Uganda

Although drought stress has been identified among the production constraints of East African highland bananas (Musa spp., AAA-EA genome), no quantitative data were available to support this assumption. This study uses data from three on-station fertilizer trials (5 6 cycles) in Central and Southw...


Asten, Piet J.A. vanFermont AMTaulya G[Drought is a major yield loss factor for rainfed East African highland banana]Drought is a major yield loss factor for rainfed East African highland banana

Reduced climatic suitability due to climate change in cocoa growing regions of Ghana is expected in the coming decades. This threatens farmers’ livelihood and the cocoa sector. Climate change adaptation requires an improved understanding of existing cocoa production systems and farmers’ coping st...


Abdulai, IssakaJassogne, Laurence T.P.Graefe, SophieAsare, RichardAsten, Piet J.A. vanLäderach, PeterVaast, Philippe[Characterization of cocoa production, income diversification and shade tree management along a climate gradient in Ghana]Characterization of cocoa production, income diversification and shade tree management along a climate gradient in Ghana

The ‘sustainable intensification’ (SI) approach and ‘climate-smart agriculture’ (CSA) are highly complementary. SI is an essential means of adapting to climate change, also resulting in lower emissions per unit of output. With its emphasis on improving risk management, information flows and local...

Key messages: Participants in policy processes require constant communication and networking among stakeholders to be able to exploit the available policy windows. The review process requires a dynamic and engaging tool. The robustness of a review tool is one step toward having a good and fruitfu...


Muchunguzi, PerezAmpaire, Edidah L.Acosta, MariolaRutting, LucasTumuhereze, MartinMwongera, CarolineOkiror, John FrancisAsten, Piet J.A. van[Scenario guided policy planning: processes, comparisons, and lessons from East Africa]Scenario guided policy planning: processes, comparisons, and lessons from East Africa

As a result of declining farm/plot size and increasing food security needs, intercropping is practised by the majority of small-scale farmers in eastern Democratic Republic of Congo. A banana-1egume intercropping experiment was conducted at the Mulungu Research Station in South Kivu Province to e...


Ntamwira, J.Pypers, P.Asten, Piet J.A. vanVanlauwe, BernardRuhigwa, B.Lepoint, P.Blomme, Guy[Effect of banana leaf pruning on legume yield in bananalegume intercropping systems in Eastern Democratic Republic of Congo]Effect of banana leaf pruning on legume yield in bananalegume intercropping systems in Eastern Democratic Republic of Congo

Farmers, researchers, extension officers and policy makers need reliable yield data on banana (Musa spp.) to make informed decisions. There are no standard yield determination methods available for Musa research. Production patterns and types vary distinctly in time and space. This requires speci...


Hauser, S.Asten, Piet J.A. van[Methodological considerations on banana (Musa spp.) yield determinations]Methodological considerations on banana (Musa spp.) yield determinations

Low soil fertility is among the important factors limiting highland banana (Musa spp., AAA-EA genome) yields in Uganda. We monitored 179 on-farm demonstration and control plots in Central, South, Southwest and East Uganda to identify constraints and opportunities to fertilizer adoption in banana ...
