Climate change and ecological intensification of agriculture in sub-Saharan Africa – A systems approach to predict maize yield under push-pull technology por Alexandridis, Nikolaos, Feit, Benjamin, Kihara, Job, Luttermoser, Tim, May, Wilhelm, Midega, Charles, Öborn, Ingrid, Poveda, Katja, Sileshi, Gudeta W., Zewdie, Beyene, Clough, Yann, Jonsson, Mattias

“…Assessing effects of climate change on agricultural systems and the potential for ecological intensification to increase food security in developing countries is essential to guide management, policy-making and future research. 'Push-pull' technology (PPT) is a poly-cropping design developed in eastern Africa that utilizes plant chemicals to mediate plant-insect interactions.PPT application yields significant increases in crop productivity, by reducing pest load and damage caused by arthropods and parasitic weeds, while also bolstering soil fertility. …”
