The aim of the PNTH Ecorurable project is to promote the development of sustainable agriculture throughout the Hainaut Cross-Border Natural Park. It sets out to promote an agriculture on a human and family scale, respectful of the environment and nature. The project is designed to meet the expectations of stakeholders in terms of sustainable agriculture jobs, product quality and the dynamism of rural life. Cross-border added value is generated through networking, exchanges and transfers of good practices on both sides of the border, but also through joint production. The target is therefore to facilitate a network of exchanges between innovative farms who are project partners; to identify the problems present on the territory on the basis of farmers' meetings (GARA) and innovative farms; to test different diagnostic tools on various themes (grassland flora, fodder, soil, optimisation of farm manure, sustainability of the farm, conversion to organic farming, etc.) then to popularise these tools with farmers and give guidelines for “self-diagnosis”; to experiment with innovative techniques (implementation and monitoring of forage trials, experimentation of cropping systems and innovative cropping practices, dissemination of results); to enable, through networking, the development and structuring of organic microeconomic sectors.
