Timor-Leste

Why this origin matters

Timor-Leste matters to anyone who grows or drinks arabica, whether or not they have tasted its coffee. A plant found on the island of Timor in 1927, resistant to leaf rust among crops of Typica, turned out to be a natural cross between arabica and robusta, and it gave breeders the rust resistance now carried by the Catimor and Sarchimor groups and their descendants. The second reason is the country itself: coffee was about a quarter of everything it exported by value in 2024 and most of what was not oil, it brings cash income to more than a quarter of its households on the 2015 census, and the Asian Development Bank describes its yields as among the lowest in the world.

Where coffee grows

The Asian Development Bank's project paper of 2018 says production is concentrated in the mountainous parts of five municipalities: Aileu, Ainaro, Ermera, Liquiçá and Manufahi. In the 2015 census, as the bank reprints it, 82 per cent of households in Aileu and in Ermera grew coffee, 66 per cent in Ainaro, 56 per cent in Liquiçá and 55 per cent in Manufahi. The 2019 agriculture census counted about 31,900 hectares of coffee on household farms, 6.3 per cent of the gross area those farms cultivated, which made coffee the fourth crop by area after maize, rice and cassava. The bank describes the way it is grown: coffee bushes planted under larger shade trees that form continuous forest, with food crops such as banana and taro, and spices, grown in the same system. None of these documents gives production by municipality.

About two hundred kilograms a hectare

Two independent sources arrive at nearly the same low figure by different routes, and in different units. The bank's staff estimated the yield of arabica at about 200 kilograms of green bean equivalent a hectare in 2018, against a world average it put at 743. The university survey of 825 households in Ermera measured an average of 204 kilograms of parchment-equivalent a hectare for the 2011 harvest, and found that about 60 per cent of households were below 100. Parchment weighs more than the green coffee inside it, so the survey's figure is the lower of the two; the study also notes that 2011 was a poor year, 25 to 40 per cent below the harvests on either side.

Both explain it the same way: old trees that are rarely pruned or replaced, little weeding or composting, and almost no purchased inputs. The census gives a sense of scale. In 2019 it recorded 52 household farms in the whole country using any fertiliser on coffee.

Training has not obviously changed this. In the survey only 14 per cent of households had received any training on coffee in the previous four years, and those that had reported yields about 6 per cent higher, a difference the authors call strikingly low and probably overstated. The bank adds a reason growers hesitate to prune or replant: pruning or replanting means an initial loss of income while the trees return to production, which the paper says is likely to deter poor households.

Species and varieties

The documents CoffeeHQ read speak of arabica, and say little else. The bank's yield estimate is for arabica; no document read gives a share for robusta or for any variety, and none says how much of the Timor Hybrid is planted in the country that shares its name. What the scientific record does give is the starting point: the review of coffee leaf rust that CoffeeHQ uses says the hybrid was found on Timor among crops of Typica, which suggests that Typica was being grown there in the 1920s; no document read describes what was planted in Portuguese Timor at the time. The household survey and the bank agree on the condition of the trees today: old, overgrown, often too tall to pick, and under shade that has not been pruned.

The plant found among the Typica in 1927

The classic arabica lines, Typica and Bourbon, are susceptible to coffee leaf rust. The resistance breeders went on to use came from Timor. A 2017 review of the disease says the Híbrido de Timor populations derive from a single plant discovered on the island in 1927 that showed resistance to rust among crops of Typica, and that in the 1950s these populations were shown to be natural hybrids between arabica and Coffea canephora, the species robusta belongs to. A genome study published in 2024 gives the same year and calls the plant spontaneous: nobody made the cross.

A cytogenetic study of 2013 looked at what is held to be that first plant, kept alive by cuttings and catalogued by the Portuguese rust centre as CIFC 4106. Its abstract reports that the plant has three sets of chromosomes where arabica has four, formed from one reproductive cell of each parent species, and calls it the supposedly first plant: the word is the authors' own caution. Five other Timor Hybrid accessions the study measured differ from it in their DNA content. Because CIFC 4106 has been considered the first of them, the authors suggest that the others arose from reproductive cells of that plant carrying an irregular number of chromosomes: a suggestion, in an abstract, and the only part of the paper CoffeeHQ could read.

The World Coffee Research catalogue takes up the story a generation later. In 1958 or 1959 the Centro de Investigação das Ferrugens do Cafeeiro, the rust research centre that the review says was created in Portugal in 1955 with American and Portuguese government money, received two shipments of Timor Hybrid seed from the island and selected two plants from them for their resistance. Crossed with the compact Caturra they produced the Catimor group; crossed with Villa Sarchi, the Sarchimor group. The two sources give different years for the breeding. The review says the centre began a programme to transfer the hybrid's resistance to the main arabica cultivars in 1960; the catalogue says breeders in Portugal began work on resistant varieties of compact stature in 1967. They may be describing different stages of the same work, and neither says so.

Three cautions belong here. The sources CoffeeHQ read name the island, not the estate or district where the plant stood, so this entry does not repeat the more detailed accounts that circulate. The catalogue itself says only that the hybrid appeared in the 1920s. And both the review and the catalogue report that resistance derived from the Timor Hybrid is breaking down in several of its descendants.

Harvest

No document read gives a national harvest calendar. The one dated observation is from Ermera in 2011: a household survey charted coffee income arriving from April to September, and timed its second visit for August and September because the harvest had just ended. The export tables show what follows. In 2024 the months from August to December carried more than half of the year's exported tonnage, and February was the largest single month. The tables do not say which harvest a shipment came from.

The months before the harvest

The same survey visited each household twice in 2011 in order to compare the season after the harvest with the season before it. In February half of the households were eating one meal a day or fewer on average; in August, just over a fifth were. Forty-five per cent ate fewer or smaller meals in February than in August. The share of people kept from their daily activities by ill health was 6.6 per cent in February and 1.5 per cent in August.

Coffee made up 53 per cent of household income on average, and two-thirds of households earned 250 dollars or less from that year's crop. The authors' conclusion is that a single annual payment, with no means of saving it, turns a low income into months of hunger, and that higher yields alone would not end that. These are findings from one municipality in one poor harvest, fifteen years ago, and the entry gives them as that.

How the coffee is processed

What the sources describe is a choice between selling fruit and selling parchment. In the 2011 Ermera survey 68 per cent of households sold cherry, and most of those sold nothing else; the remainder pulped and dried their coffee and sold it as parchment or as dried bean. The 2019 census counted 9,298 households using a coffee pulping machine. The bank's paper lists pulping fresh coffee and drying it among the tasks households share. No document read names a processing method beyond this, and none gives the share of the crop that is washed or dried in the fruit.

Cherry today, or parchment later

The Ermera survey asked growers what they sold and why. Cherry fetched mostly about 50 US cents a kilogram in 2011 and parchment a little under two dollars. Since about five kilograms of cherry make one of parchment, the study points out, the household that pulped and dried its own coffee earned less for more work.

Fewer than one in a hundred growers gave price as the reason for their choice. Sixty-two per cent said they sold cherry because they needed the money quickly. Cherry has to be sold within a day of picking, and the survey's month-by-month chart shows cherry sales early in the season giving way to parchment later, which the authors read as fruit that could not reach a buyer in time. About 81 per cent of cherry sales went to one buyer, the cooperative; almost all parchment went to other large companies.

How it is graded and sold

Timor-Leste exported 4,191 tonnes of coffee in 2024, worth 17.7 million US dollars, on its statistics institute's tables, which count green, roasted and ground coffee together. The United States was the largest destination by value and Indonesia by weight, followed by Japan, Australia, Germany, Portugal and Belgium. Exports swing widely from year to year: 7,521 tonnes in 2021 and 3,739 in 2020. The bank's paper said in 2018 that most of the coffee left as a commodity-grade product with little differentiation, and that the country had no national standard for grading fresh or processed coffee; it proposed one. CoffeeHQ has not read whether a standard was adopted.

History

The bank's paper gives the outline, and credits a study by Shepherd and McWilliam that CoffeeHQ has not read. The first significant plantings were made in the 1860s, when the Portuguese colonial authorities required households in some areas to plant coffee. Between 1890 and 1920 large private and state-owned plantations were established with the colonial government's support. After that the sector grew through planting by smallholders, some on their own initiative and some under government programmes that the paper says encouraged or coerced them. A 1922 trade history, written from the other side of the island, lists Timor coffee as shipped through Kupang and credits it to both the Dutch and the Portuguese halves.

Planted by order, then sold through one company until 1994

The Asian Development Bank's account of the Indonesian period is brief and specific. From 1975 to 1994 one company held an exclusive licence to manage the plantation sector and the coffee trade. The Indonesian military played a substantial part in that trade, and the price paid to smallholders was as little as a sixth of the price paid elsewhere in Indonesia. The paper says this contributed to a loss of knowledge, and that under-investment brought a steady decline in what the plantations produced.

The state-backed monopoly ended in 1994. The paper says new business models and markets have been developed since, and that efforts to rehabilitate unproductive farms had begun by 2018 with a very large amount of work remaining. It does not name the company, and it does not describe the events of 1999 or what they did to the farms. Read with the compulsory planting of the 1860s, the outline, which is CoffeeHQ's reading of two short paragraphs and not the bank's own sentence, is of a crop that households in some areas were made to plant under one administration and that growers had to sell through one licensed channel, cheaply, under the next.

One consequence is still in the land records. The paper says about a quarter of the land planted with coffee is owned by the state and occupied by smallholders without clear title, and cites a 2016 survey in which 17 per cent of households in Ermera and 12 per cent in Ainaro saw some risk of being dispossessed within five years.

Pressures on the sector

• Yield. About 200 kilograms a hectare on two separate estimates, from trees that are old and seldom pruned.
• Land. About a quarter of coffee land is state-owned and farmed without clear title, on the Asian Development Bank's account.
• A single yearly payment. In the one survey that measured it, food ran short in the months before the harvest.
• Quality and price. In 2018 most coffee left as an undifferentiated commodity and there was no national grading standard.
• Dependence. Coffee was most of what the country exported other than oil in 2024, and export volumes halve and double between years.

Institutions worth knowing

• Ministry of Agriculture and Fisheries: the public body the Asian Development Bank names as responsible for coffee and other agroforestry crops, and joint publisher of the 2019 agriculture census
• Timor-Leste Coffee Association (ACTL): a voluntary trade association formed in 2016, whose founding members the bank says accounted for about 67 per cent of exports that year
• Café Cooperative Timor (CCT): the cooperative that bought about 81 per cent of the cherry sold by households in a 2011 survey of Ermera
• National Institute of Statistics of Timor-Leste (INETL): the statistics institute that publishes the coffee export tables
• Centro de Investigação das Ferrugens do Cafeeiro, Oeiras, Portugal: the coffee rust research centre that received Timor Hybrid seed and bred from it
