World heritage and the agrarian trilogy

leave a comment »

WHR_agri_landscapes_3Agricultural 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.”

Stari Grad plain - ancient Greek farming in the Adriatic. The farming land is divided into regular sized parcels known as chora (Greek for landscape or countryside), bounded by drystone walls. All this, together with the cisterns and the little beehive-shaped toolsheds was first measured and marked out some 2,400 years ago and they have remained unaltered in their layout and in continuous use since the ancient Greeks created them.

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.

The area of the Konso, in Ethiopia, is characterised by extensive drystone agricultural terraces contouring the hills and giving the landscape its unique characteristics. After harvesting in September, the parallel lines of the terraces and their engineering and artistic workmanship can best be appreciated.

“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.

In a short and insightful commentary in the latest issue of the Unesco Courier, Vanderlan da Silva Bolzani has discussed ‘chemodiversity’ as being “one component of biodiversity”. It’s a truth we often miss or overlook. The latest issue of the Unesco Courier, 2001 January-March, celebrates 2011 as the International Year of Chemistry.

Since the Earth Summit (Rio de Janeiro, Brazil, 1992), da Silva Bolzani has written, the exploitation of natural resources and the socio-economic benefits of bioprospecting have become increasingly poignant issues. One of the principal goals of the Convention on biological diversity, which was adopted at the Summit, is “the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of the benefits arising from the utilization of genetic resources.” But bioprospecting, which consists of making an inventory of the components of biodiversity with a view to ensuring their conservation and sustainable use, has, on the contrary, not ceased to be misused to further the interests of industry, which often patents the substances as they are found.

The tenth Conference of Parties to the Convention, held in Nagoya (Japan) in October this year, will change the picture, though, as it reached a legally binding agreement on the fair and equitable use of genetic resources. As from 2012, this Protocol will regulate commercial and scientific relations between countries which possess not only most of the organic substances, but also the knowledge – often non-scientific – surrounding these resources, and those countries wishing to use them for industrial purposes. A new page has turned in the history of the exploitation of the extraordinary chemodiversity of so-called ‘megadiverse’ countries.

Chemodiversity is one component of biodiversity. Secondary metabolites – alkaloids, lignans, terpenes, phenylpropanoids, tanins, latex, resins and the thousands of other substances identified so far – which have a whole host of functions in the life of plants, are also playing a crucial role in the development of new drugs. And, although we are living in the era of combinatory chemistry, with high-speed screening and molecular engineering, we still continue to turn to nature for the raw materials behind many medically and economically successful new treatments. Nature has provided over half of the chemical substances that have been approved by regulatory bodies across the world over the past 40 years.

The man who (almost) sold his mother for fertiliser

Five recent news features from the IPS (Inter Press Service) network describe problems of agriculture and livelihood in Africa and South America. The report from Malawi is shocking – of how a young man attempted to sell his mother so as to buy fertiliser!

Thou Market, southern Sudan. Across the Sahel, women generate income from balanites seeds, which are about half oil and a third protein. After processing at home, they can be turned into many tasty items, including roasted snacks and a spread not unlike peanut butter. They also supply a vegetable oil that is a prized ingredient in foods as well as in local cosmetics. (From 'Lost Crops of Africa: Volume III: Fruits', The National Academies Press.

Climate Change Means New Crop Health ConcernsIn Brazil, the Climapest project has brought together 134 researchers from 37 institutions to evaluate the potential effects of climate change on crop health, and to guide policies and provide options so that this South American and global agricultural leader can adapt. The changes in climate “will not necessarily aggravate the crop diseases” in all cases, because warmer temperatures or increased carbon gases could impede the proliferation of certain microorganisms, but it is important to be ready for future scenarios because “generating solutions takes time,” explained Raquel Ghini, project leader.

Funguses, viruses and other agents that are harmful to agriculture are among the organisms that react fastest to changes in the climate, because of their short life cycles and their ability to reproduce quickly. Climapest began in January 2009 and has a four-year mandate to study 85 problems of plant health affecting 16 crops, including major exports like coffee, soybeans and fruit (banana, apple and grape), as well as African palm and castor oils, both of which are gaining ground as raw material for biodiesel.

Small Scale Farmers Face Uphill Battle – “Small farmers need substantial infrastructure to be competitive. If not, we can’t deliver according to our clients’ needs,” said Alan Simons, an emerging small-scale farmer in South Africa. “Big farmers kill you, they flood the market,” he added.

“Bigger farmers have an advantage over smaller farmers because smaller farmers face bigger obstacles to getting into the market,” said Chair of the Department of Agricultural Economics at the University of Stellenbosch, Professor Nick Vink. “Geographically they are mostly further away from the market, infrastructure is often geared to working with large quantities of produce, the transaction costs of working with small amounts of product are higher, and last but not least they get no support from the state.”

Zinder, Niger Republic. Aizen occupies some of the hottest, driest locations ever faced by plant life in the modern era. Yet it not only survives, it yields enough useful products to sustain human life almost by itself. In at least a dozen countries, people virtually live off aizen fruits, seeds, roots, and leaves. The bushes typically give a lot of fruits, which mostly ripen at once. The fruits shown here are unripe, and would normally be collected only after they turn yellow. But because of the food shortage, people are often unable to wait that long. ((From 'Lost Crops of Africa: Volume III: Fruits', The National Academies Press. Photo: Eden Foundation)

So how do small farmers cope? “Marketing holds the key to making profits”, said Jeptha. “You need to have contracts and a proper market. Your produce should be sold before you plant them. You must know where you are going to deliver it before you plant that seed,” he said. Farming short cycle crops is also key. Simons farms green beans, baby marrows and gem squash – crops that can be harvested within eight weeks. Small farmers don’t venture into fruit farming. It can take up to three years for fruit trees to bear fruit, a major risk for the emerging small farmer who has little start up cash.

Desperation Over Subsidies – Many needy farmers are being left out of a government fertiliser and seed subsidy programme in Malawi, and are employing desperate measures in order to access these commodities. A 21-year-old man, Jolam Ganizani, from Malawi’s central district of Ntchisi, is in police custody after he attempted to sell his own mother to use the money to buy fertiliser and seed.

Police prosecutor Sub Inspector Peter Njiragoma told local journalists last month that Ganizani had confessed to the police that he was so poverty- stricken that he felt that selling his mother would be the solution to his problems. “He had wanted to use the money obtained from selling his mother to buy farm inputs which would assist him to grow a lot of crops and harvest more,” explained Njiragoma.

Few trees on earth engender respect like baobab. Millions believe it receives divine power through the branches that look like arms stretching toward heaven. The baobab is entrenched in the folklore of much of Africa. This is partly because of its singular appearance but also because of the cures and the foods it provides.

According to the police, Ganizani was working with a herbalist in Mozambique who advised him that his mother could be used as a slave by businesspeople. Malawi is highly susceptible to human trafficking because of high levels of poverty, low literacy levels and HIV/AIDS, according to a local NGO, the Malawi Network Against Child Trafficking, MNACT.

New Vegetables in Kenya’s Food Markets – Kale is also popularly known as “sakuma wiki”, a name that loosely translated means that it can sustain people throughout the week due to its extreme affordability, particularly for those who earn a dollar and below a day. It is thus the single most popular and available vegetable. “In spite of its popularity, varieties of kale available to farmers are generally of poor quality, yield easily to diseases and their production is also low,” explains Catherine Kuria.

Vegetables are grown by an estimated 90 percent of Kenyan households, with Kale accounting for the highest production. In a bid to improve food security and consequently alleviate hunger, new varieties of kale have been developed that are more productive and can cope better with the unpredictable climatic changes across the country. These new varieties are expeted to aid a government programme called ‘Njaa Marufuku Kenya’ which basically means eliminating hunger in Kenya. This programme supports agricultural development initiatives targeting the poor in rural areas, where an estimated 60% live below a dollar a day.

Dantokpa market, Cotonou, Benin. “Mustard” made from seeds of the savanna tree commonly called locust in English is essential for making nutritious soup. Across West Africa locust bean is a major item of commerce, as is its major processed form, dawadawa, a nutrient-dense, cheese-like food. These together constitute an important economic activity for women. Production of the pungent paste is a traditional family craft and although most is produced for home use, some ends up being sold in local markets.

Rain May Disappear from South American Breadbasket – South America still has vast extensions of land available for growing crops to help meet the global demand for food and biofuels. But the areas of greatest potential agricultural production – central-southern Brazil, northern Argentina, and Paraguay – could be left without the necessary rains. Every deforested hectare in the Amazon – a jungle biome extending across the northern half of South America – weakens the system that has been protecting the region. “We don’t know where the point of no return is,” when forest degradation will become irreversible, and lands that benefited from the rains generated in the Amazon turn to desert, said the scientist Antonio Nobre, of the Brazil’s national space research institute, INPE.

The Amazon forest and the barrier created by the Andes Mountains, which run north-to-south through South America, channel the humid winds, now known as “flying rivers.” Those winds ensure rainfall for a region that is the continental leader in meat, grain and fruit exports, and a world leader in sugar, soybeans and orange juice. The flying-river phenomenon, as established by climate researchers, led Nobre and other scientists around the globe to a new theory, the “biotic pump,” which explains climate phenomena, equilibrium and disequilibrium in the Earth’s natural systems and in which forest biomes play an essential role. A large tree in the Amazon can evaporate up to 300 litres of water in a day. One measure suggests that the Amazon generates 20 billion tonnes of water vapour daily. The Amazon River, in comparison, churns out 17 billion tonnes of water into the ocean.
