Polycrises
Polycrises cannot be understood in a linear way or through descriptive interpretive dominance, but rather through exploratory cause-and-effect modeling. I have created an as-yet-unpublished model on this topic, which reveals a remarkable number of interconnections.
Transformation, Welfare, Economy
For the German Environment Agency (UBA), we first used an Integrated Assessment Model to qualitatively explore how emotionally impactful actions and spillover effects could facilitate exponential transformation. Afterwards, in a quantitative simulation model with over 4,000 factors, we divided Germany into social milieus and ran scenarios for transformation, assessing the effects on the environment, climate, economy, welfare (NWI), and satisfaction.
Energy
For the energy transition, I have developed several simulation models, including one for Germany which showed that, hypothetically, we could become completely self-sufficient, and one for the world (using WEO data), which turned most regions into economic winners. It would be feasible in any case, though with enormous implications for the supply of raw materials and the necessity of maximum electrification with underutilized electrolyzers (ToC).
Mobility
Among other things, I created a model for global battery-electric mobility for cars, trucks, buses, and short-haul airplanes and ships. The energy demand would be minimal, and current known lithium reserves would suffice. Hydrogen does not belong in the fuel tank.
Building Sector
In several projects, the focus was on energy demand in the building sector, as well as understanding the significance of reducing temperatures in hot water systems enabled by ultrafiltration techniques.
Raw Materials
The availability of critical raw materials was part of the energy transition models. These are fundamentally available, but in decreasing concentrations. This makes them more expensive, with implications for the circular economy and for countries that will only later enter the transformation. Of course, total human energy consumption also plays a decisive role, as do the geopolitical implications (see polycrises).
Artificial Intelligence
Again for the German Environment Agency, I collaborated with others on several projects addressing digitization and, through it, AI. The logical conclusions from the models—which also include softer factors—tend toward dystopian scenarios in the absence of societal restructuring. I have been working with AI in the narrower sense for over 30 years, ever since my university studies, and see potentials that do not necessarily need to be realized by me. I addressed this dissonance in my novels "The WHY of Life."
Nutrition, Agriculture, Forestry
Initially, the focus was on the potential to substitute steel and concrete with biotic raw materials, but FAO data on the development of forest and arable land, and on feeding the still-growing global population with its changing diet—taking into account intensive agriculture, organic agriculture, legumes, and much more—lead to rather pessimistic prospects. Several behaviors will need to change if we want to continue feeding the world.
Biomass Economy in Africa
Together with African stakeholders, we explored the potentials of a bioeconomy in Sub-Saharan Africa. Among the findings was the perhaps surprising realization that capital-intensive agriculture will not be of net benefit to the population. A more labor-intensive, locally organized cooperative bioeconomy that also improves soils could, however, be an alternative—from which, however, actors in industrial agriculture would benefit little.
Regime Change in an Authoritarian State
Together with experts from within Germany and abroad, we developed a scenario space for the overthrow of a government. One of several scenarios was a form of vision-driven, peaceful movement with secret support from the population, initiating change through guerrilla gardening and medical care that bypasses the corrupt structures of the country, serving as a starting point for a sweeping revolution.
SDGs
Possibly, I was one of the first scientist to to point to the fact that the SDGs are not only reinforcing in their interconnections but also balancing, in particular if we look at them from different country's perspectives. The model on know-why.net is only one example from a project in Ghana. It is worth to have a closer look not just on the international level but also on rather regional levels. Exploring this goes beyond the iSDG and other tools.
