According to the European Environment Agency, the three European archipelagos constitute a unique bioregion, known as the Macaronesian Biogeographic Region. Although, Macaronesian Region includes four Atlantic archipelagos, three of which Azores, Madeira, and Canary Islands, belong to Portugal and Spain, and one is an independent country, Cabo Verde. More however, Morocco’s coast border and some regions of Portugal (Serra da Arrábida and Algarve native forest) are sometimes included in Macaronesia Region, because of flora remains belonging or like native Laurel Forest (Laurisilva), that in Madeira is classified as a UNESCO Human Heritage. The combined population of Macaronesia reaches more than 3,200,000 people, 67% of it inhabiting Canary Islands.

The climate variate from maritime temperate in Azores to the subtropical and semiarid climate of Canary Islands. Madeira has a Mediterranean and subtropical climate. Average annual temperature ranges from 16oC to 26oC, average cumulative precipitation reaches 1,200 mm.

The Agrosus project will be realized in Madeira Archipelago, a Portuguese Outmost Region, that has been used as a genetic resources transfer and acclimation platform, characterized by rich agrodiversity, whereas coexisting European crops and cultures, with subtropical ones, introduced from the four continents. Agriculture is realized in traditional Madeiran agrosystems called Fazenda, small size farms, below one hectare, organized in one or more small terrace plots (poios), bounded by volcanic stonewalls, irrigated by water canals (levadas), that bring water from upper mountains. Madeiran fazendas historically are the first agrosystems created by Europeans in outmost territories, enriched by the traditional knowledge of mainland settlers and abroad native populations. Poios played an important function in the settlement, through the creation and organization of the territory and food security of populations.
