Heslin, A., Puma, M.J., Marchand, P., Carr, J.A., Dell'Angelo, J., D'Odorico, P., Gephart, J.A., Kummu, M., Porkka, M., Rulli, M.C. and Seekell, D.A., 2020. Simulating the cascading effects of an extreme agricultural production shock: global implications of a contemporary US Dust Bowl event. Frontiers in Sustainable Food Systems, 4, p.26.

Higher temperatures expected by midcentury increase the risk of shocks to crop production, while the interconnected nature of the current global food system functions to spread the impact of localized production shocks throughout the world. In this study, we analyze the global potential impact of a present-day event of equivalent magnitude to the US Dust Bowl, modeling the ways in which a sudden decline in US wheat production ...

Zipper, S.C., Jaramillo, F., Erlandsson, L-W., Cornell, S.E., Gleeson, T., Poorka. M. 2020. Integrating the water planetary boundary with water management from local to global scales. Earth's Future, DOI: 10.1029/2019EF001377

The planetary boundaries framework defines the “safe operating space for humanity” represented by nine global processes that can destabilize the Earth System if perturbed. The water planetary boundary attempts to provide a global limit to anthropogenic water cycle modifications, but it has been challenging to translate and apply it to the regional and local scales at which water problems and management typically occur. We dev...

Kummu, M., Kinnunen, P., Lehikoinen, E., Porkka, M., Queiroz, C., Röös, E., Troell, M., Weil. C. 2020. Interplay of trade and food system resilience: Gains on supply diversity over time at the cost of trade independency. Global Food Security, Volume 24, March 2020, 100360

Rapidly increasing international food trade has drastically altered the global food system over the past decades. Using national scale indicators, we assess two of the resilience principles that directly reflect the effects of global trade on food systems – namely, maintaining diversity and redundancy, and managing connectivity. We perform our analysis for four nutritional components: dietary energy, proteins, fat, and quanti...

Keys, P.W., Porkka, M., Wang-Erlandsson, L., Fetzer, I., et.al. 2019. Invisible water security: Moisture recycling and water resilience. Water Security Volume 8, December 2019, 100046

Water security is key to planetary resilience for human society to flourish in the face of global change. Atmospheric moisture recycling – the process of water evaporating from land, flowing through the atmosphere, and falling out again as precipitation over land – is the invisible mechanism by which water influences resilience, that is the capacity to persist, adapt, and transform. Through land-use change, mainly by agricultu...
