Topics

The Heath Nexus Wiki organises its content around a set of recurring scientific and policy domains. These topics reflect the areas where technical complexity and public debate most frequently intersect — and where factual, well-sourced reference material adds the most value.

Nitrogen & Ammonia

Ammonia emissions, atmospheric deposition, and their effects on nature and agriculture form one of the central themes. The wiki covers the chemistry of the nitrogen cycle, Dutch and European nitrogen policy, the AERIUS dispersion model, critical deposition values, and the gap between model outcomes and field measurements.

Climate & Energy

This domain covers the physics and economics of the energy transition: greenhouse gases, climate modelling and its uncertainties, levelised costs of energy (LCOE and VALCOE), wind and solar capacity factors, nuclear energy, hydrogen, and biomass. The emphasis is on quantitative analysis rather than advocacy.

Food & Agriculture

Food systems sit at the intersection of chemistry, biology, logistics, and policy. Topics include food processing and preservation technologies, alternative proteins, manure and phosphate policy, and the environmental footprint of agriculture.

Health & Environment

This cluster addresses the effects of environmental pressures on human and ecosystem health, including air quality, fine particulate matter, and the health implications of ammonia and nitrogen deposition.

Water Management

Water quantity, quality, and governance — from groundwater and surface water to European water framework directives and the interaction between agriculture and water systems.

Policy & Governance

Across all domains, the wiki documents the regulatory frameworks, court rulings, position papers, and governance structures that shape how scientific knowledge is translated into law and permit decisions.

Further topics

Additional entries cover biodiversity, circular economy, innovation and technology, and AI-assisted research methods. These are typically cross-cutting and appear in relation to the primary domains above.
