Coffee Boom, Coffee Bust and Smallholder Response in Vietnam’s Central Highlands Dang Thanh Ha and Gerald Shively* Abstract This paper studies the recent boom and bust in Vietnam’s coffee economy. Data from smallholder coffee farms in the Central Highlands are used to examine responses to a drop in producer coffee prices. A multi- nomial logistic regression model is used to identify several factors associated with four specific patterns observed among coffee farmers: no response to price change, reductions in use of purchased inputs, changes in crop mix, and responses aimed at enhancing liquidity through off-farm work or borrowing. Patterns of response are shown to have differed systematically across sub-groups of smallholders. Policy implications raised by the findings are discussed. 1. Introduction Introduced by the French in the 1850s, coffee remained relatively unimportant in Vietnam until the 1980s (de Fontenay and Leung, 2001). In the decade between 1990 and 2000 Vietnamese farmers, approximately 80% of them smallholders (Greenfield, 2002), planted more than a million hectares of Robusta coffee, enabling Vietnam to surpass Colombia as the world’s second-largest coffee producer (ICO, 2002). In the 1990s coffee production increased at an annual average rate of 30% and by the end of the decade coffee was providing as much as 10% of Vietnam’s annual export earn- ings. A number of factors help to explain the rapid growth of the coffee sector in Vietnam, among them a policy of privatization and economic liberalization (Doi Moi), state-sponsored migration, and price spikes generated by frosts in Brazil. During the mid-1990s the economic benefits of Vietnam’s coffee boom spread rapidly and were far reaching. By mid-decade more than one million Vietnamese were participating directly or indirectly in the country’s coffee economy (Nhan, 2002). Vietnam’s entry into the world coffee market, combined with rising stocks, inelastic demand and a shift toward low-cost Robusta for processing (Ponte, 2002) helped con- tribute to a precipitous decline in international coffee prices, to below 40 cents a pound in late 2001—a three-decade low in constant dollar terms (Brown et al., 2001). 1 Figure 1 presents producer coffee prices and harvested coffee area in Vietnam over the period 1990–2002. The figure clearly illustrates Vietnam’s basic coffee story: a steady expan- sion of coffee area in the latter half of the 1990s and simultaneous erosion in producer prices. Of course, fluctuating fortunes for smallholders is a phenomenon unique to neither coffee nor Vietnam.

Coefficients of variation for these com- modities typically range between 30 and 70% when calculated using annual average prices and more than 100% when based on monthly data. Price fluctuations such as those in Figure 2 are important for several reasons. On the supply side, many countries rely heavily on just a few primary commodities, including agro-industrial crops for export earnings, so that fluctuations in prices lead directly to fluctuations in incomes and account balances. On the demand side, price cycles have been shown to affect trade flows as well as inflation rates in importing and exporting countries (Cashin et al., 2000; Barichello, 2000).

The focus here is the collapse in coffee prices, which has attracted much attention. Pérez-Grovas et al. (2001), Varangis et al. (2003), and Maluccio (2005), provide analyses of the “coffee crisis” from Latin American perspectives. Charveriat (2001) and Mehta and Chavas (2004) offer global perspectives. In the case of Vietnam, de Fontenay and Leung (2001), the World Bank (2004), and Lindskog et al. (2005) con- clude that the collapse in coffee prices had important effects throughout the country, and reversed the fortunes of many smallholders. For example, for three consecutive years beginning in late 1999, producer prices in Vietnam were insufficient for most farmers to cover the variable costs of coffee production (USDA FAS, 2002, 2003). Not surprisingly, one of the most acutely affected areas has been the largest coffee- producing area in Vietnam, Dak Lak province (Table 1). In Dak Lak, overproduction and subsequent price dampening had “a serious negative impact on the livelihoods of Vietnamese coffee producers” (ICARD and Oxfam, 2002, p. 1).Although coffee prices recovered modestly in the 2002–03 production year, many smallholders in Dak Lak and elsewhere continue to struggle with low producer prices.Vietnam’s on-going coffee crisis is widely acknowledged within and outside the country, and finding ways to improve outcomes for coffee farmers remains a key component of Vietnam’s agricul- tural strategy. 2 In this paper data from 1999 and 2003 surveys of smallholder coffee farmers in Vietnam’s Central Highlands are used to study how farmers coped with declining coffee prices. Data from the 2003 survey are employed to estimate a multinomial logis- tic model to measure the factors associated with four specific patterns observed among smallholders: no response, changes in input use, changes in land use, and cash enhance- ment. The role of ethnicity in conditioning these responses is studied, as well as the importance of irrigation access and farmers’ subjective outlooks regarding coffee prices. We find farmers’ responses were fairly mixed, and that lowland Kinh migrants were more likely to change crops, borrow, or engage in off-farm employment than Table 1.

The patterns suggest both farm- and farmer- specific constraints on smallholders’ ability to respond to declining agricultural prices. 2. Study Site and Data Coffee is grown in a variety of locations and by a variety of farmers in Vietnam. Given this diversity generating a survey sample that broadly represents coffee growers is difficult. Here, we focus on a sample drawn from one of the most important coffee districts of Vietnam, in the Central Highlands province of Dak Lak. In 2001 the total coffee area of Vietnam was 566,800 hectares, of which the Central Highlands accounted for 476,800 hectares. Within the Central Highlands, Dak Lak province accounted for 257,100 hectares and roughly 50% of total national coffee output. Of Dak Lak’s 16 districts, Cu M’gar has the largest coffee area, representing roughly 14% of the total coffee area of Dak Lak. Our data come from the Ea Tul catchment, in Dak Lak’s Cu M’gar district. 3 The study area has undergone tremendous economic and social change in recent decades. Following reunification in 1975, the government of Vietnam designated Dak Lak as a New Economic Zone (NEZ) and established hundreds of state farms and cooperatives in the area, most of them emphasizing industrial crops. As a result of the NEZ designation, population density increased more than five-fold in just four decades (from 17 people per square kilometer in 1975 to more than 90 people per square kilo- meter in 2002). Most of this migration consisted of an influx of ethnic Kinh farmers (Vietnam’s majority) from densely populated lowland areas. For example, although the Kinh originally represented a very small proportion of the population of Dak Lak, by 2000 their share in the provincial population had risen above 70%. Migration was ini- tially induced by government programs, but beginning in the late 1980s and early 1990s substantial migration into Dak Lak occurred spontaneously. By 2000, the province’s population stood at 1.8 million people, of which approximately 400,000 were members of ethnic minority groups. Smallholders control approximately 80% of the coffee area. The remainder is controlled by the Vietnam National Coffee Coporation (VINACAFE). The rise of Vietnam’s coffee economy nearly doubled GDP in Dak Lak within a decade—from $204 per capita in 1990 to $390 per capita in 2000. 4 But rapid agricultural growth has raised both environmental and social concerns. On the envi- ronmental front, many observers note that coffee production in Dak Lak has tended to follow an extensive, rather than intensive, path. For example, in the decade between 1990 and 2000 an estimated two-thirds of coffee output growth was due to area expan- sion (ICARD and Oxfam, 2002). This rapid area expansion led to substantial forest destruction. Although Dak Lak still contains some of the most extensive forests in Vietnam, forest clearing has been severe (De Koninck, 1999) leading to habitat and biodiversity loss (UNEP-WCMC, 2000). Total land for agricultural production in Dak Lak doubled in the 1990s, with an average increase of 46,000 hectares per year. A majority of newly claimed land has been used for cash crop production, notably coffee. Due to the rapid expansion of land for agriculture, the forest-covered area decreased from 90% in 1960 to 57% in 1995, and then to less than 50% in the late 1990s. Between 1980 and 2000 Dak Lak lost forest at an average rate of 20,000 hectares per year (ADB, 2003). In the Ea Tul catchment, forest area was reduced from 58% in 1980 to 20% in 2000 (Ha et al., 2001). From a social perspective, a massive influx of Kinh farmers into areas of ancestral importance to ethnic minorities led to a series of land conflicts between migrants and COFFEE BOOM AND BUST IN VIETNAM 315 © 2007 The Authors Journal compilation © Blackwell Publishing Ltd. 2007 316 Dang Thanh Ha and Gerald Shively © 2007 The Authors Journal compilation © Blackwell Publishing Ltd. 2007 local ethnic minority people, and between various migrant populations (ADB, 2003). Although many minority farmers have benefited from Vietnam’s coffee expansion, minority groups are widely perceived to be economically disadvantaged vis-à-vis their Kinh counterparts. This conjecture is partly supported by data from our sample indi- cating significantly higher per capita incomes among Kinh farmers (7.6 million VND on average in 2003, compared with 4.4 million VND for non-Kinh respondents). The inability of ethnic minorities to benefit from and respond to general economic incen- tives is an issue that remains high on the stated agenda of policymakers in Vietnam, and significant challenges to reducing poverty among these groups remain (ADB, 2000; Doutriaux et al., 2006). Below we address the extent to which Kinh farmers were able to respond in a different way from their non-Kinh counterparts to the collapse in coffee prices. Table 2 contains a summary of data from our smallholder surveys. 5 The stratified random surveys were conducted by a team from Nong Lam University as part of a larger study of rural livelihood in coffee-growing areas of the Central Highlands. The surveys cover agricultural production and household activities in 1999 and 2003. The observations do not represent a panel, but the sample households were drawn from the same area, namely the four communes of Ea Tul, Ea Kpal, Ea Pok and Quang Phu. The two samples are similar in most respects. The main exception is that rice Table 2.

COFFEE BOOM AND BUST IN VIETNAM 317 © 2007 The Authors Journal compilation © Blackwell Publishing Ltd. 2007 production was far less prominent in the 1999 survey (66% of households vs 25% in 2003) and off-farm employment was far more widespread in the 2003 survey (43% vs 13% in 1999). All farmers in both rounds of the survey planted and sold coffee. The economic rewards of producing coffee in Dak Lak have been very substantial for coffee-growing smallholders, on average. For example, a disaggregated poverty map for Vietnam indicates that poverty rates in southern, coffee-growing districts of the Central Highlands are markedly lower than those in northern districts, where less coffee development has occurred (Minot, 2000). Our survey data indicate average annual household nominal incomes in the study areas of approximately 25 million VND (US$1828) in 1999 and 46 million VND (US$2560) in 2003. 6 Translated into per capita terms, these incomes are roughly equivalent to GDP per capita in Vietnam (US$430 in 2002), a remarkable pattern insofar as poverty in Vietnam tends to be highest in rural areas. While this underscores the importance of coffee as an income- generating mechanism in the Central Highlands, our data also suggest that the crop has nevertheless diminished in importance in recent years. Households derived 87% of total income from coffee in 1999 and 77% in 2003. Thus while total household income rose slightly, on average, between the 1999 and 2003 surveys, the total share of income derived from coffee production fell. This reflects lower prices and an ongoing process of crop and income diversification that began following the coffee price col- lapse in the mid-1990s. Table 3 contains data illustrating the broad patterns of activity diversification in the samples. These data suggest widespread diversification of activities among the sample farms and a rising proportion over time of households reporting either planting multiple crops or engaging in off-farm employment. For example, the proportion of households that reported planting two or more crops increased between 1999 and 2003, and the proportion that reported planting three or more crops nearly doubled. 7 Simi- larly, the proportion of households reporting off-farm employment increased from 13% in 1999 to 43% in 2003. Only the proportion of sample households that reported engaging in livestock sales was lower in the later round of the survey (53% compared with 39% in 1999). The remainder of the paper focuses on the extent to which these patterns and more specific reactions to the collapse in coffee prices can be explained by features of the sample respondents. Table 3.

Household Responses to the Price Collapse We begin the analysis of household response to the collapse in coffee prices by exam- ining data on broad indicators of behavioral response, as reported retrospectively by households when interviewed in 2003. Table 4 contains data for the entire sample of farms, and separately for those below 1.5 hectares (small farms) and above 1.5 hectares (large farms). Note that 1.5 hectares corresponds to the average farm size in the sample. This split places 66% of the sample in the small farm category. The median farm size in the 2003 sample was 1.2 hectares. During the 2003 survey respondents were asked to report how they responded to the collapse in coffee prices. We should note that we made no attempt to tie the drop in the producer price of coffee to a specific reference year because not all farmers perceived the downward trend in price the same way (in part due to some modest but short-lived price recovery in 1998). Instead, the survey simply aimed to record self-reported responses to falling prices. As a result, some farmers in the sample may have reported how they responded to the price drop following the 1995 growing season, whilst others may have reported how they responded in the 1998–2002 period. In all instances, we allowed farmers to report multiple responses. We included specific categories of response and also allowed open-ended descriptions of changes in household activities and practices. As a result, column sums in Table 4 exceed 100%. Most households, however, reported only a single major category of response to the collapse in price. Nearly a third of the sample reported no change in strategy or activity. In the case of an annual crop, the theory of a profit-maximizing farmer would suggest that the primary response to a price reduction should be a reduction in planted area (Askari and Cummings, 1976). In the case of a perennial crop, however, optimal short- run responses to a price decline need not follow this pattern, since long-run consider- ations regarding investment and disinvestments in trees may come into play. 8 As indicated in Table 4, in our sample the most common reaction to the drop in price, Table 4.

Source: survey data. regardless of farm size, was a reduction in the amount of fertilizer applied to coffee. A slightly larger proportion of small farms than large farms reported a reduction in fertilizer use (45% vs 35%), although this difference is not statistically significant. While this reaction clearly reflects a desire on the part of households to reduce cash expenditures, it also reflects the tendency of households to shift resources out of coffee and into other crops, without abandoning coffee completely.In fact, a number of house- holds reported that while they reduced fertilizer use in coffee, they simultaneously increased fertilizer use on other crops, especially corn and black pepper. This basic pattern is further underscored by the complete elimination of fertilizer by 17% of households in the sample, and the reduction or elimination of irrigation (typically requiring the use of electric or gasoline pumps) in 19% of households. 9 Somewhat sur- prisingly, a statistically higher proportion of large farms reported a complete cessation of irrigation or fertilization. This may reflect a greater capacity to withstand a loss in income on larger farms and a tendency to maintain production on small farms, even in the face of falling prices. Nevertheless, a significantly larger proportion of small farms reported removing coffee trees (8.0% vs 2.8%) and a larger proportion of small farms reported planting new crops in response to falling coffee prices. Roughly similar (and small) proportions of households reported borrowing as a direct result of falling prices. Small farms were slightly more likely to seek off-farm employment or to sell livestock. No household reported selling land. Taken together, the data in Table 4 suggest that small farms were somewhat less responsive to falling coffee prices than large farms, and that a disproportionate share of large farms were sufficiently buffered from their reliance on coffee that they could treat their investment in trees with a certain degree of benign neglect (foregoing both irrigation and fertilizer) while waiting for coffee prices to recover. Questions that naturally emerge from Table 4 are whether patterns of response sys- tematically differed, and whether differences can be explained by household features. To answer these questions a more detailed analysis is undertaken using a multinomial logistic regression. This approach requires collapsing the categories appearing in Table 4, so as to maintain the opportunity for econometric estimation of coefficients of interest. Accordingly, we create four broad categories of response, q = {1, 2, 3, 4}. Into category 1 we place those households that reported no response to the price collapse. Into category 2 we place households that reported input reductions, i.e. reductions in fertilizer or irrigation rates. This includes households that eliminated fertilizer or irrigation entirely. Category 3 contains households that changed crops, either by removing coffee trees or by planting new crops in combination with existing coffee. The final category includes households that directly enhanced liquidity, either by borrowing money (formally or informally), seeking off-farm employment, or selling livestock. When households reported multiple responses, a unique category was assigned, with changes in crops at the top of the hierarchy, followed by liquidity enhancements and reductions in inputs. Table 5 contains results for our four equation multinomial logistic regression where no response is the omitted response category.

Overall, several statistically meaningful patterns emerge from the data, with nine statistically significant coefficient estimates.

Some evidence points to village differentials, especially in the case of reduced input levels, but no evidence suggests responses were conditioned by education. 10 Several patterns emerge with respect to four fixed factors: irrigation source, farm size, number of workers, and security of tenure. In each case, one would expect these factors to influence the range of possible response, and in each case statistical evidence supports this conjecture. In the case of the irrigation source, which here is coded as a binary indicator of whether the household used a well as a source of irrigation water, households with an established well (a relatively reliable source of irrigation water compared with the alternatives, such as a stream or pond) were more likely to seek enhanced liquidity through non-agricultural means. Within the study site, the water demands of coffee are quite high, and competition for water is frequently reported by farmers. The regression results suggest farmers without a secure source of irrigation water were more likely to shift land or inputs away from coffee. Results also suggest large farms were more likely than small farms to reduce or eliminate inputs (i.e. fer- tilizer and irrigation). That the correlation between farm size and borrowing is weak in this sample is somewhat surprising given Duong and Izumida’s (2002) evidence of a link between land ownership and access to credit in Vietnam.The pattern found here likely reflects the uniformly low rates of borrowing as a response to price reductions in the sample. Household labor capacity emerges as an important explanatory factor in the regres- sions. Not surprisingly, households with a larger number of workers per hectare were more likely to seek off-farm employment. They were also more likely to reduce input levels, probably as a reflection of higher immediate requirements for cash and food in larger households.To gauge the importance of tenure security in conditioning response, we include in the regression a measure of farm ownership. During the survey, respon- dents were asked to identify tenure status for all of their plots based on three main categories: (1) area owned and documented by a government-issued land use certifi- cate (n = 200), (2) area under tribal control but not documented by a government- issued land use certificate (n = 14), and (3) area recently cleared and not documented by a government-issued land use certificate (n = 43). As indicated by the sum across categories, several households held land under more than one category. A variable “percentage of land owned” was constructed using total farm size, net of area rented in or out, as denominator and total area documented by government-issued land use certificates as numerator. Land ownership was positively correlated with the likelihood of reducing input levels. The weak correlation of land ownership with other categories of response indicates in part the small degree of variation in the land ownership vari- able, and in part the fact that households with high rates of ownership were the least likely to change their behavior in response to the price fall. The final variable included in the regressions is the respondent’s expectation regarding coffee prices. During the survey each respondent was asked to forecast the minimum, expected, and maximum coffee price for the next growing season. The expected price, expressed as a ratio of the respondent’s price to the sample mean response, is included as a conditioning variable in the regressions. Other things equal, households that had above average expectations regarding the future coffee price, vis-à-vis their sample cohorts, were less likely to change crops compared with the reference group. Within the context of this sample, crop changes seem to be largely driven by price expectations. Changes in input use, in contrast, are conditioned by external factors and household characteristics.
