2.1 Descrição curta da tecnologia

Definição da tecnologia:

For centuries, the population of the highlands of central and south-western Madagascar has sustainably managed and conserved the local tapia woodlands.

2.2 Descrição detalhada da tecnologia

Descrição:

These woodlands play an important economic role as a source of non-timber forest products (NTFP) such as wild silk, fruit, mushrooms, edible insects, and herbal medicines. Tapia trees (Uapaca bojeri) comprise up to 90% of all trees in these woodlands, bear an edible fruit, and their leaves nourish an endemic silkworm (landibe). Landibe silk is used to produce ritual burial shrouds throughout the highlands. Trading silk products and tapia fruits is a crucial source of cash income for the local communities. The tapia woodlands are maintained by the local villagers through burning and selective cutting. Burning favours the dominance of pyrophytic (fire-tolerant) tapia trees and protects silkworms from parasites. Selective cutting of non-tapia species and pruning of dead branches also favours tapia dominance and perhaps growth. Other common species include the endemic Sarcolaena eriophora and the invasive Pinus patula/khasya. The Tapia woodland is clearly an anthropogenically shaped forest. However, the creation and maintenance of the woodlands should be seen as positive transformation rather than a form of degradation.
Local and state-imposed regulations protect the woodlands from overexploitation. The Forest Service has placed restrictions on forest cutting and burning while allowing for traditional use rights. The collection of forest products is regulated through a type of common-property regime. For example, fuelwood collection is limited to dead trees or fallen branches. It is forbidden to break off large branches to access cocoons. Thanks to these protective regulations, forest boundaries are mostly stable, and woodland density has increased in several cases.

Comentários:

Traditional method; no establishment phase and costs.

4.8 Fatores mais importantes que afetam os custos

Descreva os fatores mais determinantes que afetam os custos:

The estimation of costs is difficult - fruit are gathered over a two month period by school children going out for an hour in the early morning each day; the silkworms are collected by individuals (usually experienced collectors) on free days. In some areas, projects exist that run silkworm nurseries, establish firebreaks in the woodlands, grow and plant tapia seedlings, and finance the purchase of silk looms. These projects obviously require much larger budgets.

Comentários:

The larger rainy season silk harvest provides crucial cash income during the meagre months before the rice harvest. In 1998 the price of 200 cocoons was between US$ 0.10-0.15. For a basket of Tapia fruits villagers earned between 0.02-0.06 US$/ kg. During

6.8 Pontos fracos, desvantagens/riscos da tecnologia e formas de superá-los

Pontos fracos/vantagens/riscos na visão do/a compilador/a ou de outra pessoa capacitada	Como eles podem ser superados?
Partly individual indiscriminate cutting and/or strong use of fires leads to overuse of the forest resources	needs clear regulations, guidelines and observation of the rules by the local authorities as well as awareness raising about the multiple benefits of the forests. As long as the communities continue to be interested in the forests and its products, they will protect it from destructive cutting.
Invasion of exotic tree species such as pine and eucalyptus from private and village woodlots	the forest service has rightly been encouraging communities to cut these trees from the tapia forests without the need for complicated permits.
Insecure land use rights	in 1996 a new legislation opened the way to officially decentralize management of state-owned renewable natural resources to adjacent communities, which would aid woodland protection by increasing stakeholder involvement.
In some areas, silkworm populations have been very low for decades	recent projects seek to establish silk nurseries and reintroduce the worm
