Ylva has mostly worked with research in small-scale agroforestry and cropping systems in the tropics, mainly in East Africa but also in Southeast Asia. She has tried to find connections between different parts of the agricultural systems in order to be able to find and weigh the necessary trade-offs and identify potential synergies through the farmer's eyes.
Ylva has worked with both qualitative and quantitative methods to better understand climate adaptation, farm management practices, economy and labour, gender roles, the role of advisory services and the role of trees and livestock in more or less complex agricultural systems for different functions / ecosystem services on small-scale farms in western Kenya.
Nowadays, Ylva works more with the role of extension services in small-scale agriculture in the project AgriFoSe2030 and with research that links land, vegetation and livestock with human livelihood and health in a project in arid areas in Kenya and Uganda (Drylands Transform).
Ylva has taught within a few courses on topics like agroforestry, participatory field methods, soil chemistry etc and has supervised BSc and MSc students in writing their thesis and carrying out their field work.
Ylva is currently working in two projects with collaboration and research in sub-Saharan Africa and southern and southeast Asia.
She has a MSc in Agronomy (finished in 2004) with international focus.
Her dissertation in crop production science was about smallholder farm management and priorities and how they are balancing productivity, livelihood, climate adaptation and ecosystem services. It was completed in 2020.
