The Netherlands faces a confluence of two critical and interconnected challenges: the nitrogen crisis and the protein transition.These issues are symptomatic of a broader societal debate about land use, sustainability, and the future of agriculture. Contentious aspects include balancing the expansion of urban areas with preserving natural habitats, managing agricultural emissions while ensuring food security, and addressing the economic impacts of transitioning to sustainable practices. As I argued in a recent interview, the question underpinning these challenges is simple yet profound: what do we want our country to be?

Part 1: The Nitrogen Crisis – A Spatial Planning Issue

At the heart of the nitrogen problem lies the excessive emission of ammonia (NH₃), primarily from livestock farming. This has led to stringent government policies that have strained farmers, businesses, and broader society. As a physicist and modeler by training, I see significant flaws in how nitrogen models are used to guide policy. These models, while valuable as tools for monitoring and scenario analysis, have often been applied in a reductive and rigid manner.

One of the key failures is the lack of integration between disciplines. Decisions about nitrogen are deeply tied to spatial planning—an area where the Netherlands once excelled. My father, as part of the team that designed and developed Southern Flevoland, worked in multidisciplinary teams of engineers, urban planners, and sociologists. Their approach balanced long-term visions with immediate practical decisions. Today, such integrated thinking seems lost, in part due to shifts in governance that prioritize sectoral policies over interdisciplinary collaboration. Changes such as increased bureaucratic fragmentation and a reliance on short-term managerial goals have replaced the long-term, multidisciplinary approaches that once defined Dutch spatial planning. We rely on fragmented decision-making processes where jurists and managers dominate, often paralyzing progress.

The nitrogen debate exemplifies this. Policies have been reduced to calculations of critical deposition values (critical loads), which in turn narrow the focus to ammonia emissions. While these are valid considerations, they fail to address the larger question: how should we organize our land to balance agriculture, nature, and urban development?

Part 2: The Protein Transition – An Opportunity for Change

Parallel to the nitrogen crisis is the ongoing protein transition—the shift from animal-based to plant-based proteins. This movement is not just about sustainability but also about recalibrating our agricultural systems. Livestock farming consumes vast resources, from land to feed crops, while generating significant environmental externalities, including ammonia emissions.

The transition to plant-based proteins presents an opportunity to mitigate these challenges. For example, reducing livestock numbers could lower nitrogen emissions, freeing up land for other uses or more sustainable farming practices. Yet, this transition is not without hurdles. Plant-based protein products, such as meat alternatives, are often priced higher than their animal-based counterparts due to inefficiencies in scaling production, higher costs of raw materials, and underdeveloped supply chains compared to the well-established meat industry. These barriers must be addressed to make sustainable diets more accessible.

One potential solution is to implement policies that incentivize sustainable practices while disincentivizing resource-intensive ones. This could include taxes on meat and dairy products or subsidies for plant-based alternatives. However, such measures must be balanced to ensure they are socially equitable and do not disproportionately burden lower-income households.

Part 3: The Need for a Broader Vision

What ties these issues together is the need for a cohesive national vision for land use. The Netherlands is a small, densely populated country. Balancing competing demands for housing, agriculture, industry, and nature conservation requires a return to integrated spatial planning. The nitrogen crisis and protein transition are not isolated problems; they are symptoms of a larger failure to define and pursue a shared vision for the future.

Modern tools, such as scenario modeling and gamification, can support this process. For example, in Germany, scenario modeling was used to assess land use changes for renewable energy projects, enabling policymakers to balance ecological preservation with energy goals. Similarly, gamification tools have been employed in urban planning to simulate the impacts of zoning changes, fostering more informed community discussions. Imagine using interactive models to explore different visions for the Netherlands—from rewilding large swathes of land to creating high-tech agricultural hubs. These tools could help policymakers and citizens visualize trade-offs and make informed decisions.

Part 4: Moving Forward – A Holistic Approach

To address the nitrogen crisis and accelerate the protein transition, we must adopt a holistic approach. This means:

1. Reintegrating Disciplines: Bring together scientists, policymakers, and practitioners to craft solutions that account for ecological, economic, and social dimensions.
2. Redefining Metrics: Move beyond critical loads and ammonia emission levels to broader indicators of sustainability, including biodiversity, soil health, and societal well-being.
3. Engaging Citizens: Foster public dialogue about land use and sustainability to build consensus around difficult trade-offs. Start a national discussion about the future of the Netherlands. What kind of country do we want to build?
4. Leveraging Technology: Use scenario modeling and gamification to make complex policy decisions more transparent and participatory.

The nitrogen crisis and protein transition challenge us to rethink how we live, farm, and consume. Addressing these issues requires adopting a holistic approach: reintegrating disciplines, redefining sustainability metrics, engaging citizens in public dialogue, and leveraging tools like scenario modeling to guide decision-making effectively. By reconnecting these debates to the larger question of what kind of country we want to be, the Netherlands can turn these challenges into opportunities for innovation and progress.
