Description

The PhD aims to assess intensified intercropping systems among smallholder farmers' farmers in southern Mozambique. The objective is to answer the following question: how will intercropping intensification affect productivity, its variability, environmental attributes, and ecosystem services such as nutrient cycling if farmers migrate from their currently practiced low-input intercropping systems to high-input intensified systems?

The study hypothesizes that the performances of intercropping systems are greater and lower than those of sole crops in low and high input contexts, respectively. Indeed, we hypothesize that in high-input systems, plant-plant competitions in intercropping are greater than in low-input systems.
