World heritage and the agrarian trilogy
Agricultural landscapes have been honoured in the quarterly journal published by Unesco, ‘World Heritage’, which has dwelt (issue number 69) on the agro-pastoral landscapes created by human activity and serves to explain the major sites of this type now inscribed on the World Heritage List. The number has said: “The most impressive of these sites are perhaps the terraced fields found around the world, in the Far East, Africa, the Andes and all around the Mediterranean basin, with rice paddies and various wine-growing areas, some of which are also listed as World Heritage cultural landscapes.”
The introductory note has said that human civilisation, throughout its history, “has applied certain principles of adaptation to the environment that are sufficiently resilient to drive nature’s inherent and inexhaustible dynamism by adding a cultural dimension that endows it with uniqueness”. Culture and cultivation has become a reality in the agricultural landscapes, for their age and their continuous evolutionary aspect.
In these sites, the territories are structured by agro-pastoral practices known as the ‘agrarian trilogy’: the cultivation of fields – agriculture (from the Latin ager, fields); the cultivation of forests – silviculture (silva, forest); and husbandry – with the use of so-called uncultivated lands
such as sustenance pastures together with their pastoral routes, all of which, taken together, was termed saltus in Roman times.
The journal has found that most impressive of all these landscapes are those devoted to a single operation, “because the structure they impose upon the territory in terms of a single variable results in large expanses of land that are spectacularly homogenous”. This is seen in the various rice fields, in the impressive landscapes of Tequila (Mexico) where the blue agave is cultivated, and uniquely apparent in such vineyard landscapes as the Upper Middle Rhine Valley (Germany), Wachau (Austria), Saint Emilion (France), Tokaj (Hungary), Pico Island and Alto Douro (Portugal), and Lavaux (Switzerland).
The journal number also includes an interview with Parviz Koohafkan, the coordinator of the Globally Important Agricultural Heritage Systems (GIAHS) of the Food and Agriculture Organisation (FAO). In response to a question about the global evolution of this heritage category and recognition of the intrinsic interaction between people and nature, Koohafkhan replied that this category of World Heritage is gaining ground because of the importance of the landscape approach and the nature-culture relationship.
“In addition, landscapes are evolving rapidly due to agricultural transformation and unless we plan and work with communities for the sustainability of their livelihoods, we will be unable to conserve this agriculture and landscape heritage. FAO, UNESCO and their partner organisations should set up further collaborative programmes to address issues of food and nutrition security within the context of the post-Rio sustainable development agenda and to recognise the important role of small-scale family farms and indigenous communities in providing multiple goods and services,” Koohafkhan has said.
The immense diversity of agricultural systems can be seen in the vegetable, animal and even mineral produce that they include, is a valuable point made in a short article from the International Scientific Committee on Cultural Landscapes (IFLA-ICOMOS). Discussing agricultural landscapes in a heritage context, the ingredients of the trilogy are well supplied: basic foods provided by cereals (wheat, rice, maize, etc.) or tubers (potatoes, manioc, taro, etc.), each of which forms the foundation of a major area of civilisation that subsequently spread around the world.
Then there are fruit-bearing plants (vines, olive and apple trees, citrus fruit, date and banana trees, etc.), the juice of which could be fermented (wine, cider, etc.); oleaginous plants (olives, sunflower, soya, colza, oil palms, coconut and argan trees, etc.), sugar-bearing plants (cane and beet); stimulant plants (coffee, tea, cocoa and tobacco, etc.), which produce alkaloids and undergo elaborate transformation (drying of leaves, roasting of grains, etc.); textile plants (flax, hemp, cotton, jute, etc.); ruminants, which provide milk, meat, wool and leather but are also used as beasts of burden in numerous agro-pastoral systems; equidae, camelids, pigs, poultry and so on.
