This is a broad question, which I would tackle by looking at timescales. Flower strips and organic farming are interventions that usually lead to results that can be observed within a few seasons. Agroforestry depends on trees, which are slow growing organisms, so the variety of impacts (positive and negative) will play out over the lifetime of the added trees. That is typically measured in rotations, ranging from less than 10 years for energy coppices to over 40 for some high-value timber species.
So, if you are comfortable with longer-term planning, agroforestry is very much for you: depending on where you are (soils, climate, local markets...), and what you're comfortable with, you'll be looking at improvements in biomass productivity (the so-called land equivalency ratio) of anywhere between 10 and 50%.
