Moisture recycling is a hydrological process that captures the journey of water particles in the atmosphere - starting with terrestrial and oceanic evaporation, continuing with their windborne transport, and ending with precipitation back on land and ocean. Land cover affects the amount of recycled precipitation, and hence the ways we, as humans, use, manage, and govern land concern moisture recycling. Moisture recycling is scarcely managed and governed currently, despite being increasingly recognized as an important process in the biosphere, supporting our society. Moisture recycling is one of the many processes entangling forests and agriculture at various scales, as part of forest-agricultural social-ecological systems. Forests have the potential for securing precipitation for downwind agriculture, although the understanding of this process within the broader forest-agricultural systems remains limited and improving this understanding requires an interdisciplinary approach. As our biophysical understanding of moisture recycling progresses, a question arises: how can we use the knowledge of moisture recycling to guide our activities on land that safeguard forests and agriculture synergistically? The thesis attempts to answer this question by applying a social-ecological systems perspective and an interdisciplinary approach to investigate the interdependence between forests and agriculture through moisture recycling. By applying the forest-agricultural systems context and beyond, the thesis further assesses the need to govern moisture recycling as a mediating process in social-ecological systems. Five papers in this thesis cover different scales of social-ecological processes entangling forests and agriculture. Paper I analyzes moisture recycling at the national scale, to conceptualize its interconnection with forests, agricultural production, and crop trade across countries globally. Paper II focuses on the regional scale dynamics of moisture recycling and the role of forests as moisture sources during heatwaves in Europe. Paper III zooms in on the local scale to detect changes in local forests and shifting cultivation practices as a result of social-ecological pressures on land in the Democratic Republic of Congo. Paper IV complements Paper III with an investigation into the moisture recycling process connecting local forests with local agricultural practices. Finally, Paper V uses a futuring exercise to imagine the governance of moisture recycling as economic goods at diverse scales. Together, these papers suggest that forests support downwind agricultural production through the provision of precipitation within and across scales. This relationship is reciprocal, considering that forests are also influenced by the state of downwind agriculture through social dynamics. Accordingly, moisture recycling unravels a new way of interdependence between forests and agriculture. This thesis advances the moisture recycling knowledge beyond its biophysical aspects, and prompts us to reflect on what governing moisture recycling in the future would entail.
