Will farmers in the tropical world be among the foresters of the 21st century through agroforestry systems?

Today it is certainly easier and more efficient to ask 1 million farmers with various agroforestry systems (AFS) based on coffee, cocoa, rubber, coconut or cloves to include 10 trees in their AFS than to plant and monitor over 20 to 40 years forest plantations of timber or energy in the tropics to achieve the same number of trees planted.

Introduction

The main tropical AFS are often referred to as complex: multi-stage and multi-species.

They most often include :

  • Fruit growers, for self-consumption or sale if the market permits),
  • Energy wood trees (Eucalyptus spp, Acacia mangium etc)
  • Timber trees for self-consumption (house manufacturing among others) or local sale, or even export (teak…)

It can be based on i) coffee or cocoa, with shade trees for shade around 30%, ii) rubber trees or also specific trees such as damar (Shorea javanica or durian/surian in Indonesia with fruit trees or timber trees, iii) idem with cloves in AFS or in parks in Madagascar and iv) with coconut including possibly also livestock and v) home gardens.

After a strong deforestation linked to the establishment of all perennial crops, AFS allows to consider a kind of reforestation with an important biodiversity. In the plains of Sumatra and Kalimantan in Indonesia, part of the plant biodiversity is now in the AFS following the disappearance of forests.

1- The main AFSs that include timber and energy wood are today :

  • the old jungle rubber, with seedling rubber trees in Indonesia, or clonal rubber AFS in Thailand, Indonesia and Sri Lanka;
  • shade trees for coffee and cocoa, or producers have realized that planting mahogany (Mahogany) is more profitable at the end of the life cycle than planting the classic shade trees that are worthless when cut;
  • coconut-based fruit and miscellaneous systems in natural palm groves in West Africa;
  • fruit-based systems such as Acai, Copoadzu etc. in the Amazon.

2-Examples of ASF with timber

Energy wood is very present (i) in the Sahel for household energy needs, (ii) in Madagascar on the east coast in the ASF a clove for feeding stills for distillation (iii) in the Comoros for Ylang-Ylang: old local trees, old fruit trees, eucalyptus, pine, Acacia mangium and the others are all used and valued for this purpose.

For lumber, production often depends on the national policy on “tree tenure”, either the tree belongs to the farmer and he can sell it, or it does not belong to him and the interest in promoting its cultivation is questioned (the case of Ivory Coast in particular):

  • in Thailand: teak, mahogany for the local market in high demand;
  • in Indonesia: Acacia mangium, Albizzia falcataria and A. lebbeck, teak, Nyatoh and to a lesser extent Meranti, Surian etc…
  • in the Amazon, mahogany and cocoa, acai and mahogany…
  • in Nicaragua: coffee and cedrella, Coyote and Mahogany…

Another form of valuation concerns fruit trees with valuable wood: durian, for instance.

One of the major issues concerns the balance between native vs. introduced species.

3- Effectiveness of quality reforestation programs for forestry companies

Sustainable cultivated forests are a success in Europe.

In comparison, few logging companies have made investments in sustainable plantations in Sumatra or Kalimantan except Java Teak plantation – a notable exception, which have been remarkably managed since 1815. This failure in Indonesia and globally throughout South East Asia is due to low interest due to too a long return on investment (35/50 years) etc.

In tropical areas, if there is no effective reforestation at the level of forestry companies, who is able to produce quality timber trees, at a lower cost, without significant investment and with the possibility of waiting for many years ?

4- The peasant : the future forester?

Who is best placed to integrate trees into complex AFS or even simple AFS (coffee or cocoa shade…)? The answer is probably on the side of the farmers who insert the trees in current agroforestry systems without major problems at marginal cost, or even possibly in “woodlot” (mini forest plot) as in Kenya. The sine qua non condition is that the farmer benefits from his investment: that the “tree tenure” policy gives full ownership of the rights and uses of the tree to the person who grows it.

Of course, there are still problems of access to quality plant material (pine, teak, Mahogany…).

Markets play a major role in creating production opportunities:

  • Mainly local markets such as in Thailand or in all tropical countries where the need for timber is increasing due to a galloping demography;
  • Some niche markets: guitar woods (mahogany, ebony, all woods comparable to Mahogany: Pau ferro, faux mahogany, Senegalese mahogany (Kaya senegalensis), burr wood for high quality furniture, various woods for marquetry etc ….
  • the “export” markets seem less interesting compare to the past due to the European and American production and a disaffection for tropical wood;

Access to markets and the specific type of market are therefore the keys to the development of decentralised, atomised, non-specialised forestry, and with the concomitant development of local intermediaries capable of processing trees from field felling to timber transformation (sawmill).

It is necessary to promote access to services for the collection and processing of trees by third parties with an equitable distribution of the margin by the different actors.

Farmers will thus have a better cost-effectiveness ratio for this type of plantation and a great flexibility of integration and maintenance of the trees in existing systems: in SAFs, woodlots, hedgerow systems, etc.

The national policy must integrate a “tree tenue policy and right favourable” to the production of wood by farmers and recognize their rights, thus securing the rights of farmers over their trees.

It would be better to involve ALL stakeholders, perhaps in systems such as “innovation platforms” including producers, private tree cutting and processing services, transport, forestry companies, raw wood processing companies (sawmills, artisans, etc.), etc.

The possible role of certification remains to be explored because none of certification is currently in place for wood produced by farmers.
