Major sources of Flemish N emission are agriculture (59% of total emission) and transport (21%); 95 percent of the ammonia emission is reported to come from agriculture. In this government's view, it looks like Flanders is unpopulated. In Flanders, 6,800,000 inhabitants show an average urea production of 20 g/day, or 3.65 kg N/year. This urea production eventually ends up in wastewaters as ammonia. Human urea production represents the grand total of 24.8 kl N/year. However, this contribution is made invisible in the statistics. Flemish reports mention a grand total of 33 kt/year, so Flemish numbers appear to be incomplete. Human production has not been taken into account. When calculating human N excretion in Flanders, 24.8 kt N/12.322 km2 is obtained, corresponding to an additional N load of ± 20 kg/ha. Implementing human N excretion into the calculation thoroughly changes the situation: adding human N production results in peak loads of 40 kg N/ha.

In parallel, the aims and structure of these ERNs were translated at the federal and regional levels, resulting in the creation of the Flemish Network of Rare Diseases. In line with the mission of the ERNs and to ensure equal access to care, we describe as first patient pathways for systemic sclerosis (SSc), as a pilot model for other rare connective and musculoskeletal diseases. Consensus was reached on following key messages: 1. Patients with SSc should have multidisciplinary clinical and investigational evaluations in a tertiary reference expert centre at baseline, and subsequently every three to 5 years. Intermediately, a yearly clinical evaluation should be provided in the reference centre, whilst SSc technical evaluations are permissionably executed in a centre that follows SSc-specific clinical practice guidelines. In between, monitoring can take place in secondary care units, under the condition that qualitative examinations and care including interactive multidisciplinary consultations can be provided. 2. Patients with early diffuse cutaneous SSc, (progressive) interstitial lung disease and/or pulmonary arterial hypertension should undergo regular evaluations in specialised tertiary care reference institutions. 3.
