    Slide 1 : Title

The previous papers on Brazil at this conference have dealt with the oils derived from cultivated

    plants. In this presentation, I shall focus on three products of the so-called ‘extractivism’ industry in Amazonia.

    ‘Extractivism’ is a term used to describe the harvesting of indigenous, wild forest resources.

My specific subjects are the products of wild growing trees; namely, namely rosewood oil, copaiba

    balsam and tonka beans. These three commodities have been exported by Brazil to the international

    fragrance and flavour industry for around a century.

For those of you unfamiliar with the geography of Brazil, allow me first to show the location of the

    Amazonian region.

    Slide 2 : Greater Amazonia

     Greater Amazonia is the world’s largest rainforest area and covers parts of Brazil, the Guianas, Venezuela, Colombia, Ecuador, Peru and Bolivia. The Brazilian Amazon region is highlighted in

    green on the map.

In Brazil, the natural forest area of Amazonia has reduced in the past few decades as a result of

    ranching, slash-and-burn agriculture, logging and mining. These developments have impacted to

    varying degrees on the availability and accessibility of all three of my subject commodities. For most

    of my discussion on operations today, I shall be referring to a more restricted area that is accessed

    from the free port city of Manaus in the state of Amazonas. This area is illustrated in slide 3.

    Slide 3 : Manaus region

The natural occurrence of rosewood, copaiba and tonka lies in the more remote, wild forest areas.

    Since road systems are restricted to the developed areas, access to the raw materials is by the

    traditional method of navigation of the tributaries of the river Amazon. Therefore, you may regard

    my story as an excursion by boat into the rainforest.

    Slide 4 : River photo

My intention is to review and to explain the causes of the changes in production over the past few

    decades and to indicate possible future trends.

    ROSEWOOD (also known as bois-de-rose and pau rosa)

The oil of rosewood is obtained from the trunk and branch wood of Aniba rosaeodora Ducke and

    closely related species. These trees are slow growing evergreens of the Lauracaea family which are

    indigenous over a wide range of the Greater Amazon Region from the Caribbean coast (the Guianas

    and Venezuela), through the northern and central areas of the Brazilian Amazon and across into

    neighbouring Colombia and Peru.

    The steam distilled wood oil is obtained in a yield ranging around 1% and up to 90% of the oil consists of optically active linalol.

    Production of one drum (180 kg) of oil requires 15 tonnes of wood, equivalent to 5 or 6 trees, depending on their diameter. Harvesting of the trunk of mature trees results in their destruction.

    Several countries in the region produced rosewood oil up until the 1950s but, thereafter, Brazil has been the sole supplier to the market.

Production and Marketing Systems

Harvesting and distillation

    The general methods of harvesting and distillation have not changed for over 50 years. At the commencement of the dry season in May, an experienced ‘scout’ seeks out natural stands of rosewood trees close to the riverbanks of the Amazon tributaries. When an economically worthwhile stand is found, a team of about 30 harvesters arrives and fells the trees. Traditionally, the cut wood is manually carried in 1 metre lengths to the riverbank. Some companies, however, introduced mini-tractors to make transportation easier in the late 1980s. The cutting season spans May to October.

Distillation of the wood is carried out in one of three locations :

    ? at the riverbank in the collection area, using mobile distilleries that have been shipped

    upstream;

    or, after shipment of the logs downriver,

    ? at fixed distilleries in towns in the interior; and

    ? at fixed distilleries in Manaus.

    Shipment downriver of wood and of the oil produced by mobile distilleries occurs only in the wet season (December to April) when there is a sufficient depth of water for boats in the upper reaches of the rivers.

    Virtually all of the distillery equipment today is very old. Prior to distillation, the wood is reduced to a small size, using a mechanical wood chipper. Distillation pots range in chip holding capacity from 200 to 1,000 kg and the distillation time varies from 2.5 to 5 hours per batch.

The oil marketing system

Oil produced at distilleries finds its way to market by one of three routes :

    Distiller ? direct export by a few distillers (via Manaus); } 70%

    ? sale to Manaus traders who export from Manaus; }

    ? sale to a branch of a multinational in Sao Paulo or Rio (and 30%

    this may be under a rolling, fixed price contract arrangement).

Very little rosewood oil is used in products sold on the domestic consumer market. Purchases by

    local branches of the multinational fragrance companies are effectively for onward shipment to their

    overseas headquarters.

Some of these companies compound the oil prior to export and these shipments appear under a

    different classification to rosewood. The published official figures for total Brazilian exports of

    rosewood oil from Manaus and other cities, therefore, can be significantly less than the actual

    production level in most years.

Over 95% of exports are destined for Western Europe and the United States with the latter taking on

    average around 60% of Brazil’s exports.

Changes in Production and Exports

Slide 14 shows a 50 years series for recorded exports of rosewood oil by Brazil. It reveals that the

    scale of the trade has declined dramatically from the 300(+) tonnes level of the 1950s.

The decline history may be considered to have involved three phases :

Phase 1 (1960s/70s)

The initial and major loss of market commenced during the 1960s, following the introduction of

    comparatively inexpensive synthetic linool. Rosewood oil usage as a source of linalool isolates and

    for direct incorporation in low cost fragrances disappeared.

     6

    For a number of years, rosewood production exceeded demand and high unsold stocks were held in Manaus.

Phase 2 (the 1980s)

    During the 1980s, some further erosion of demand occurred with the reintroduction to the market of Ho wood and Ho leaf oils from China. On the basis of lower cost, the Ho oils displaced rosewood in middle-price range applications, such as extenders for lavender. During this phase, rosewood usage became restricted to incorporation in the higher priced range of fragrances.

    However, rosewood oil production had restructured and, during this phase, producers controlled output to fairly closely match demand at around an annual average of 100 tonnes.

Phase 3 (the 1990s)

    Another dramatic decline phase has been experienced in the more recent period. Annual output was erratic in the early 1990s and progressively reduced to an average of around 50 tonnes per in the past few years. Direct exports from Manaus have averaged 30 tonnes and purchases by the Rio and Sao Paulo based multinationals have been about 20 tonnes each year.

    This new phase has been marked, also, by an increase in sale price (as shown in slide 16).

During the recent period, the USA has frequently been forced to buy significant quantities via

    Europe (especially France). This is an indicator of a tight supply situation.

Indeed, the recent phase 3 period differs from former years in that the decline in trade has primarily

    arisen from supply problems, rather than from a major downturn in demand.

Causes of the downturn in production during the 1990s

The 1990s rundown in the scale of the industry have arisen from :

    ? rising production costs and unattractive profit margins, combined with

    ? increasing intervention by the Brazilian National Institute for the Environment and Natural

    Resources (IBAMA).

Tree availability and accessibility

In the early 1950s, rosewood trees were widely distributed and readily accessible along the banks of

    the rivers Curuauna, Tapajos, Parintins, Maues, Nhamunda, Uatumã Negro, Purus and Madeira.

    During the following two decades, the scale of extraction annually amounted to some 25,000 tonnes

    of wood (or 10,000 trees). This led to the virtual extinction of breeding populations along the river

    banks in many areas of the main producing states of Para and Amazonas.

By the 1980s, access to mature natural stands became progressively more difficult and effectively

    confined to a number of areas in central Amazonas. Even in these areas, trees with a desirable breast

    height diameter (dbh) of greater than 30 cm are today found only 2 km or more distant from

    riverbanks.

     8

    Nature has also added accessibility difficulties in that El Ninio effects in the early 1990s reduced rainfall in some years. This lowered river depth and the distance that boats could travel upstream.

IBAMA regulations

    A decree was published in the 1940s that required the replanting of 9 self-sown seedlings for every barrel of oil produced. This was observed to varying degrees within the industry.

However, major government interventions did not occur until the more recent period. The new

    regulations were stimulated by a United Nations (FAO) listing in the late 1980s of rosewood as ‘an endangered species’. The Brazilian government response is regarded by the industry and by the scientific community as a measure to protect and rationalize rosewood exploitation.

    It is broadly agreed that a high loss of biodiversity resulted over an extensive area from the ‘industrial mining’ phase during the 1950s to 1970s. However, there is no threat of species extinction since many populations remain in the interior, including those in areas that will be inaccessible to the industry for the foreseeable future (such as in Tapajos and Xingu). Moreover, the recent reduced scale of the industry has a minimal effect on the tree population and good natural regeneration can be observed today in many areas that were harvested decades ago.

    The first of the new IBAMA regulations were published in April 1992 and the most recent in May 1998. In summary, these regulations specify :

    ? the areas where rosewood extraction is not permissible;

    ? a prohibition on cutting trees of less than 20cm dbh;

    ? the volume of wood that may be extracted annually by the industry;

    ? the requirement for companies to prepare a sustainable management plan and obtain IBAMA

    for extraction;

    ? carrying out reforestation proportionate to the extraction; and

    ? the possession of an IBAMA certificate for export.

    The 1998 regulations specify that the annual limit of extraction by the industry is 2,000 trees. Current estimates by the industry are of extraction of around 1,700 trees annually (approximately 5,000 tonnes of wood), i.e. well within the limit.

The impact of costs plus regulations

The IBAMA regulations have caused general frustration within the industry over the 1990s,

    especially as those remaining in the industry at the beginning of the decade were highly committed to the objective of sustainability.

    Putting aside the frustration at remote civil servants, the key factor during the 1990s for many companies has been the costs of running an operation. Financing a tree harvesting crew must occur 6 months in advance of the possible sale of the oil product, because the seasons dictate the pattern of harvesting and produce transport on the rivers. The advance to harvesting crews is equal to 50% of the value of the wood, for which the price is around US$100/tonne. During the early 1990s, interest rates were running at in excess of 25% per month, so the advance financing placed an onerous

    burden on distillers and the profit margin after production of the oil was small.

     9

These combined factors are the reasons for half of the companies deciding ton exit industry during

    the 1990s. There has been a concomitant loss of skilled workers, who have moved into the goldfields

    or to other forms of employment.

The Future

Within the Brazilian industry, there is obvious concern about the effect on longer-term demand in

    response to reduced supply levels and increased prices. However, the core remaining players may be

    regarded as highly committed and see the industry as a ‘way of life’. All have engaged in substantial

    planting of self-sown seedlings in the harvested areas over the past few years.

It is possible that the long-term future of the industry lies with establishing formal cultivation of

    rosewood and of developing new products. This particular topic will be addressed on Thursday by

    Professor Barata of the University of Campinas.

COPAIBA BALSAM

Copaiba balsam is an oleoresin exudate that is obtained by manual tapping of the trunks of various

    wild growing Copaifera species (family Leguminosae) in the Greater Amazonian region. Copaiba oil

    is obtained by steam distillation of the balsam.

Brazil is the largest world producer of the balsam, and mainly obtains the product from C. reticulata

    Ducke, C. guianensis Desf. and C. multijuga Hayne.

Colombia, Venezuela and the Guianas are smaller-scale producers and principally exploit C. offcinalis

    Jacq.

Copaiba oil has been employed for over 100 years by the international fragrance industry as an

    aromatic fixative in perfumes and in other products, such as soaps.

A substantial domestic market exists in Brazil for the balsam for use as an antiseptic and anti-

    inflammatory product and in some other traditional applications, particularly in Amazonia.

Production and Trade of the Balsam

Copaiba trees are found around the Tapajos river in the southern part of Para state and, especially,

    along the rivers Purus, Madeira, Aripuana and Manucapuru in Amazonas state. The trees are up to 30

    metres tall and occur at about 1 to 2 per hectare.

Skilled collectors extract the balsam in the forest areas during February to July. Tapping is non-

    destructive and the same tree may be used year after year. Between 5 to 10 kg of balsam is obtained

    per season per tree, depending on its diameter. Sales are made by collectors to traders in rural towns.

    Production levels fluctuate annually since access to the forest areas is by boat and upstream sites

    cannot be visited in years of low river levels.

Manaus accounts for around 90% of direct overseas exports of the balsam. The principal export

    destinations are the USA, France and Germany. IBGE export statistics for the 1980-1992 are shown in

    slide 17. More recent export figures are not available but are estimated to be similar in magnitude with
