ACKNOWLEDGEMENTS
There were many people along the way who in one way or another contributed to this dissertation.
I owe them my
heart-felt thanks for their help and support, especially during the times when the task seemed unsurmountable. I would like to thank those individuals at the State University of New York who contributed to my development as a researcher, teacher, and as a person concerned with the human condition.
First and foremost, I want to thank Dr.
A.T. Steegmann, Jr., my advisor, mentor, and friend,
who
provided intensive guidance and training in human biology, but at the same time gave me enough latitude to explore those anthropological questions that most stimulated me.
I
would like to thank my committee members Drs. Christine Duggleby, Richard V. Lee, Ann P. McElroy, Elizabeth Randall, and Rebecca Huss-Ashmmore who contributed in a variety of ways to my intellectual and professional development.
My sincere thanks to Jean Grela who with her
expert knowledge guided me through the ins-and-outs of the anthropology program.
To Bobby Benedito, Debi Crooks, Kiko
Datar, Tim Sullivan, and David Turkon my sincere thanks for their friendship, humor, and intellectual stimulation. Ultimately the success of this dissertation is due to the help I received from many people in Lesotho.
First I
want to thank my dear friend Michael Matsumunyane who first introduced me to Lesotho and to the kindness of the Basotho i

people while he was a graduate student at SUNY Buffalo. Without Mike's encouragement this project would have never gotten off the ground.
Thanks to Douglas Ebner (former
director) and his staff at the United States Information Service (USIS) for all their help while I was in Lesotho and for their administration of my Fulbright Grant.
My thanks
to David Gittleman from the CDC for his expert knowledge on Lesotho and his extended hand of friendship.
My sincere
thanks to the many people within the Lesotho Government and various NGO's who graciously permitted me to conduct this research , offered invaluable criticism, and provided assistance.
These people include M.M. Mpeta (director of
FNCO), M.M. Ntsike (deputy director of FNCO), N. Kolane (nutritionist at FHP in the Ministry of Health),
M. Thato
(from the nutrition section of MOA), M. Pakose (nutritionist at FHP), Dr. M. Metsing (former head, FHP), and T. Khumalo (project officer at UNICEF). My sincere thanks to the following people from Mokhotlong:
Paramount Chief Mathealira Seeiso (Thabang),
Military District Officer Joseph Tsela, District Secretary Khoasi Letsisa, District Agricultural Officer Masheane Alotsi, Farmer Training Centre Coordinator Mamoswati Thobothobo, Chiefs Nkhasi Matete (Nthlolohetsane), Mojakisane Tsita
(Ha Mojakisane), Steven Molefi Phakisi
(Bfali), and Esau Majara Majara (Salang). Thanks also to Drs. Evert Kamphorst and Anton Wohlfart

at the Government Hospital in Mokhotlong for their help, insights, and their friendship. I also want to thank our field assistants Ntsepeng Monese and Mohlolo Lertholi for their fantastic work and their friendship; without their skills this research could not have be done. My greatest thanks and love to my wife Nancy RomeroDaza who, as a colleague and friend, provided me with the support and insight to make this research successful beyond my expectations; additionally, I thank her for her invaluable help in editing this manuscript.
My sincere
thanks and love to my parents Arnold and Barbara and my sisters Carolyn and Laura for encouraging me to do what I loved most. Finally, I want to thank the women and children of Mokhotlong who enlightened me and taught me about a world I only read about.
There love of life in the face of
adversity is certainly a triumph of the human spirit.
To all of you, my sincere gratitude.
David

This represents a 15% drop in a ten year period (Bureau of Statistics 1988). This decreasing agricultural base suggests serious problems for household incomes in the not too distant future. The negative agricultural situation is also reflected in the declining yields of main crops such as maize, sorghum, wheat, and beans (Ministry of Planning 1991: 21). In a 10 year period from 1977/78 to 1986/87
total yield for
all crops combined dropped by 20% (Bureau of Statistics 1990), with only maize production increasing during this period (Ministry of Planning 1991: 21).
Table 3.6. shows
the production of main crops during this ten year period.
D. Economic Infrastructure. For most of Lesotho/s history, there has been little or no industrial development.
In 1967, a year after
independence, the Lesotho National Development Corporation was established with the goal of building economic and physical infrastructure so as to create employment opportunities within the country (Ministry of Planning 1991: 23).
Today there are several large enterprises including
the Maluti Mountain Brewery (a subsidiary of South African Breweries), the flour mill in Maseru, and the multinational Highlands Water Project.
There is also a flourishing
textile industry with many small manufacturing companies, a majority of them foreign-owned.
However, in many of these
91

textile mills working conditions are quite poor and wages are very low, causing increasing discontent among workers (Ministry of Planning 1991: 24).
There are also locally
owned light industry and commercial business promoted by the Basotho Enterprises Development Corporation (BEDCO). There is an increasing demand for finished products because of the spending power of migrant laborers, civil servants, and employees of the many aid projects in the country.
This
demand has resulted in the expansion of retail and wholesale trade, especially in Maseru (Ministry of Planning 1991: 24). The growth of Maseru has also lent to the increase in service oriented business such as taxi services. Table 3.7 shows the main source of income by household type.
As expected, female-headed households (households
where there is no male contribution of economic resources) depend more on subsistence farming for income, while male headed households depend more on migrant remittances.
As
seen in Table 3.8., average income is similar between male headed and female-headed households where there is a household member with higher education (i.e., technical degree).
On the other hand, male-headed households with no
education earn higher incomes than female-managed households with no education.
These statistics support the notion of
limited access to resources in female-headed households where there is no male contribution at all.
Interestingly
enough, my data do not show significant differences in SES 92

between male- and female-headed households in Mokhotlong. This is probably due to the fact that the majority of female-headed households in my sample (called female-managed households) have males who are migrant laborers, and many of these males do contribute resources- in cash and kind- to the household. The Lesotho Highlands Water Project is an ongoing engineering scheme with the aim of exporting water to South Africa and generating hydroelectric power for Lesotho.
It
is the largest single project undertaken in Lesotho and is the largest engineering enterprise currently in Africa (Ministry of Planning: 1991: 24).
A series of dams and
tunnels are currently being constructed to channel water from the highlands to the Vaal catchment area.
The economic
impact will be great through the sale of water and from employment during the construction phase.
However, there
has been some concern that the initial estimates for employment were too high.
People have been flocking to the
project sites, located in Thaba Tseka and Katse in central Lesotho, in search of work.
Unfortunately, many have not
been able to gain employment. During my stay in Lesotho there was some unrest in the area while we were in Lesotho over the inability of the government to employ more Basotho.

E. Poverty in Lesotho. Recently Gay et al. (1991) conducted a nationwide study of absolute and relative poverty in Lesotho. Poverty was measured based on criteria defined by the Basotho themselves (Gay et al. 1991).
These criteria include the lack of the
following basic needs: 1) an adequate food supply; 2) clean and abundant water; 3) good roads and transport; 4) money to buy consumer goods; 5) wage employment; 6) medical facilities; 7) clean sanitation and toilets; 8) household furnishings and clothing; 9) fuel and firewood; 10) home and community goods; 11) secure and warm housing; 12) relevant and affordable schools; 13) livestock; and 14) fields. For purposes of analysis, the country was divided into 60 areas (with roughly equal population in each).
Poverty measures
were derived as a percentage deviation for each area and then compared to Central Maseru, the most prosperous area in Lesotho.
Figure 3.3 shows the distribution of relative
poverty in each area of Lesotho as compared to Central Maseru. While the results of this study suggest that poverty in Lesotho is in no way comparable to the situation in places like Somalia or the Sudan (there are few people in Lesotho who are starving or homeless), there is a fair degree of relative poverty which is increasing and which is unequally distributed.
Although there is relative poverty throughout
the country, the situation is worse in the mountains and 95

B. Agriculture, Fuel Foraging, and Livestock. In sub-Saharan Africa, women are the main producers of food with 70% sharing in production, 50% in storage, 100% in processing, 60% in marketing, and 100% in cooking (Saenz de Tejada 1989; Blumberg 1981).
The role of women in agriculture
in Lesotho is that much greater because of male migrant labor (Saenz de Tejada 1989).
This places an increased burden on
women who are already looking after the children and managing the household.
Moreover, while women have a great role in
agricultural production, they do not have the same access to agricultural land, training, and credit as men do (Ministry of Planning (1991: 51). Women participate in all different aspects of agriculture 179

including planting, plowing, cultivation, weeding, harvesting, and processing.
At village meetings flipitso). where
agricultural matters are discussed, it is usually women who are in the majority; they are the ones who obtain the seeds, decide who will plow, and determine whether sharecropping will take place (Ministry of Planning 1991: 151; Gay 1982). Plowing is generally done in October after the coming of the rains (for the summer crops) and in March (for the winter crops).
This work is usually done by men and boys using ox-
drawn plows; however, during this time women prepare food which they then bring out to the fields for the workers.
This
activity is time consuming since the fields that are allocated to a household are often located at a considerable distance from the house compound.
In our sample, we did come across a
very small group of women who did the plowing themselves (N=3); they told us that there were no male members in their household to do this work or that they did not have enough money to hire men to plow their fields.
After plowing, the
seeds are planted, usually by men; once again women bring food and drink to the men during this time.
After the first
sprouts appear, women spend more and more time (from October through March for maize) weeding and protecting the crops from attack by grazing livestock, birds, rodents, and from theft.
Weeding is especially laborious and time consuming and
is done mostly by women.
On several occasions I had the
chance to observe women weeding between the rows of maize; 180

they would be bending over for long periods of time, and used either hoes or their bare hands.
During the months when these
activities were going on, we had some difficulty in conducting our interviews as many caretakers were out working in the fields. After the crops are ready (around March or April), harvesting begins; there are two types of harvesting in Lesotho: green cutting, which is done throughout the ripening period, and mature harvest done when the crops are mature and dry.
Harvesting involves several activities including
"cutting, pulling, threshing, winnowing, bagging, and transporting the crop to the place of storage" (Ministry of Planning, 1991: 151). activities.
Women participate in all of these
For example they may thresh the wheat or sorghum
themselves, sort or stack them for men to thresh, or prepare food for men who are threshing; women also shell the maize and legumes, and winnow and class/sort them (Gay 1982).
After the
harvest women return to the fields to gather the dry stalks to use for winter fodder and fuel (Gay 1982).
We observed many
of these activities while collecting data, and in all cases we saw only women doing this work.
In a study of lowlanders, Gay
(1982) found that women spend nearly 15% of their time involved in agricultural activities.
No doubt, the time
devoted to agriculture increases or decreases depending on the time of year. In addition to agriculture, women spend a lot of time 181

foraging for wild vegetables (see chapter 8) and fuel.
Since
fuels such as kerosine and propane are too expensive for many rural Basotho to buy, they depend upon gathered fuels such as dung, wood, crop residue, and dried maize cobs.
The preferred
fuel in Mokhotlong is lisu which is dried and compacted cattle dung.
This fuel is slow burning and provides an even heat
(Huss-Ashmore 1982).
Lisu is easily collected from Kraals,
which are usually located in the resident compound; therefore it does not require too much time investment.
Unfortunately,
households that lack cattle usually do not have access to lisu.
The availability of this type of fuel is seasonal as
cattle are kept far-away in the cattle-posts during the summer months and in the Kraals during the winter months.
Other
types of fuel include khaoane (uncompacted cattle dung) and kholuba
(horse dung), both of which require more time to
gather as women must search for them by bridle-paths, roads, and open fields.
All of these fuels require kindling, which
is a scarce resource in Lesotho.
Women often have to walk
for hours to collect patsi (wood and dried bushes) to use as kindling or as fuel itself.
Those who have fields can collect
dried stalks and maize cobs to burn; while this is time consuming, there is some guarantee of fuel after the harvest. Finally, for those who can afford it, there is a plentiful supply of kerosine and propane in the Camp, as well as kerosine in some of the villages. We asked caretakers what types of agricultural (i.e., 182

plowing, planting, cultivation and weeding, and harvesting) and fuel foraging (i.e., the number of types of fuels they gathered) activities they participated in. Table 5.11. shows these data for the entire sample.

Table 5.12. shows agricultural and fuel foraging activities by household types.
There are significant
differences with caretakers from FMHs participating in fewer agricultural activities and collecting fewer types of fuel than their MPH counterparts.
These differences are related to
the fact that FMHs have less access to agriculture (not statistically significant) and that they tend to buy fuel (e.g., kerosine) from the market instead of foraging.

Table 5.13. shows these same data by village grouping. Again there are significant differences, with caretakers from DHHs foraging for more fuel types and participating in more agricultural activities than caretakers from CHHs.
Distant
households (DHH) have greater access to fields (p= 0.000) than CHHs.
They tend not to purchase fuel from the markets.

Table 5.15. shows the types of access to fields that households have for agricultural production.
As can be seen
44.1% of the households have their own land, while 12.8% of the households work the land for non-family members usually in return for a portion of the harvest.
Another 7.8% work on the
land of extended kin for food, while 4.1% share fields with other households, and 1.5% work on cooperative fields. 30% of the sample have no access to land.
Nearly
The majority of
these landless are located within or nearby the Camp. Table 5.16. shows the average number of fields, gardens, and crops, as well as the types of animals owned by households.
Some of the different types of crops that
households grow in Mokhotlong include maize, sorghum, peas, potatoes, beans, and pumpkin.
Garden crops include cabbage,
turnip, carrot, spinach, beet root, and pumpkin. Households may also have fruit trees such as peach and apricot trees. Finally, depending upon their affluence, households may own cattle, horses, donkeys, sheep, goats, chickens, and to a lesser extent pigs.

FMHs have
significantly fewer fields, gardens, and types of animals than MPHs.
The same is true for CHHs as compared to DHHs.
So,
it appears that both MPHs and DHHs tend to more involved in agriculture and animal husbandry than FMHs and CHHs. Our ethnographic observations support these data. 186
Reproduced with permission of the copyright owner. Further reproduction prohibited without permission.
We
found clear distinctions between households that center their activities around agriculture as opposed to those whose labor is focused on earning an income.
More often than not these
differences were based on whether or not the household was close or far from the Camp.
For example, when a caretaker
from a CHH was not home, she was often in Camp selling goods at the market or taking a child to the clinic.
On the other
hand, caretakers from DHHs were always out either collecting fuel or working in the fields.
People from DHHs spoke more
about the land and the crops; their concerns about the persistent drought was revealed to us more often, and with more urgency, than for example, by someone who lived in Camp and worked for the government.
This is not to say that there
were not CHHs that participated in subsistence agriculture or DHHs where household members worked as policeman, bank clerks, or nurses, who had little interest in agriculture. The data and our ethnographic observations only suggest a trend in decreasing dependence upon the land as we get closer to the Camp.

In Table 5.19. correlations between household economic indicators, agriculture, and fuel foraging activities are presented.
House index is negatively correlated with the
number of buildings in the resident compound, number of fuel foraging activities, number of fields, and number of crops. All of these latter variables tend to be positively associated with DHHs.
On the other hand, house index is positively
correlated (r= .42) with the number of household possessions; higher scores for house index and household possessions have 188

been shown previously to be associated with CHHs. The relationship between agricultural and livestock indicators is shown in Table 5.20.
There are moderately
high correlations between of the number of fields with the number of crops (r= .5012) and with the number of animal types (r= .5444).
Interestingly, there were no significant
correlations between the number of gardens and other agricultural or livestock variables.
We found that gardens
(individual and communal) tended to be found in households in and close to the Camp. Moreover, many of the gardens in CHHs were constantly being weeded and watered; in addition, all the space in these gardens was utilized.
Conversely, we saw a
fair number of gardens in DHHs that were dry and under utilized.

In order to examine the contribution of several economic and agricultural independent variables to the differences that appeared to be correlated with village grouping (i.e., CHH and DHH), multiple regression analysis was performed using dummy variables (CHH= 0 and DHH= l).
The use of dummy variables is
justifiable since each of the categories for the dependent variable (village grouping) contained more than 20% of the cases for the total sample (CHH= 57.4% and DHH= 42.6) (Hedderson 1991: 120).
Table 5.21. shows the results of the
regression analysis. The variables in the equation below (based on an exclusion set at p= 0.05). account for nearly 24% of the variance.

THE WORK BEGINS From the start we established good relations with the medical officers at the Government Hospital (in Mokhotlong) and among the traditional healers in the region. Mokhotlong is the only district in Lesotho where healers and hospitrl staff meet every three months to exchange information; where traditional healers are encouraged to use their skills and to direct their patients to the hospital. The first village we worked in was Thabang, a relatively large and bustling place with three distinct settlements built alongside the mountains at different altitudes. In Thabang, as in all the villages, we had to get permission to work from the village chief, who sent along one of his assistants to make the proper introductions. Six days a week we would drive out to Thabang and along the way, pile in up to 10 people looking for lifts. We would spend all day collecting data, visiting different households and getting a feel for how the people lived. As time went on we learned more and our data became richer as people got to know us and our interviewing improved. We began to learn about illnesses caused by the breaking of taboos, witchcraft and Tokolosi- an evil spirit who comes in many different forms. We saw how medicinal herbs are used for treating ailments ranging from headaches to problems with the womb. We heard about the rare practice of ritual murder for medicine and the problem of wife beating. We obtained firsthand information on the unpredictable food supply, how diet is dictated by beliefs and life stages, and how seasons and the closeness to the land affect the lives of the people. Of course, we looked at the children's seasonal growth and recorded changes in the women's weight and body composition associated with vigorous agricultural work.

CHAPTER S IX
NUTRITIONAL STATUS In this chapter I first examine the biological impact of seasonality on caretaker body weight and body composition by describing the patterns of anthropometric change across seasons for the total population and within seasons by household type and village grouping. Particular attention will be given to the relationship among fluctuating nutritional status, seasonal work, and SES. Seasonal changes in adult nutritional status can be interpreted as evidence of stress or as an appropriate response to an uncertain environment Goodman 1988; Richards 1983).
(Huss-Ashmore and
According to this latter
interpretation, it is advantageous to put on weight when food is available so as to prepare for those times when it becomes scarce; Richards (1983) suggests that this response is a reasonable alternative to storing food in the granary. Changes in weight as well as body composition may be adaptive in environments where work is highly seasonal (Dugdale and Payne 1977).
As Huss-Ashmore and Goodman
(1989) state: Seasonal storage of fat may provide energy reserves necessary to survive the "hungry season" without significant loss of muscle and working capacity. The degree and timing of fluctuation in fat and muscle mass may therefore be seen as evidence of adjustment to the seasonality of work requirements, (pg. 30).

In the second part of this chapter, I present the data on growth and nutritional status for children; again the total sample will be examined across seasons, while differences by household type and village grouping will be examined within seasons.
The children will also be compared
with their U.S. counterparts by sex and age-groups using Ztransformations and reporting data as a percentage of the median.
The focus here is not so much to make comparisons
between the U.S and Lesotho sample, but rather to look at relative change in nutritional status through time for different groups of Lesotho children. The patterns of growth for Lesotho children are similar to children throughout the developing world where mild-tomoderate undernutrition is common.
Generally, low stature-
for-age is found with adequate weight-for-stature;
this
pattern reflects the cumulative effects of undernutrition through critical periods of growth (Martorell and Habicht 1986).
In Lesotho however, this pattern of stunting may be
amplified because of the strong
seasonality
which maynot
permit adequate catch-up growth
between the
"good" andubad"
seasons.

The end result may be

After the data for caretakers and children have
been described, they will be compared with other data on rural producers from Lesotho and other countries.
I. SEASONAL BODY WEIGHT AND COMPOSITION FOR CARETAKERS. A. Descriptive statistics for body weight and composition. Descriptive statistics for body weight and composition for the caretakers by age-group are found in Tables 6.1. through 6.5.
Table 6.1. shows that body weight for the
total sample is lowest during Season 1, from late-winter through early-spring, followed by Season 3, covering a period from mid-summer through early-to-mid fall.
These
seasons coincide with the end of the post-harvest period when food becomes more scarce and the time-period when agricultural labor is most intensive, respectively.
Body
weight, body mass index (BMI), triceps and subscapular skinfolds were all highest during Season 2, a period covering from mid-spring through early summer. One-way ANOVAS were used for the entire sample in order to determine whether or not there were significant differences in seasonal weight by age group. A posteriori tests (Student-Newman-Kuels? SNK) were then employed to determine which age groups, if any, showed significant differences (at p= 0.05).
Significant weight differences by
age group were found in Season 1 (p= 0.02) and Season 3 (p= 0.05), and a marginally significant difference was found in 197

Season 2 (p= 0.06).
In Season 1, caretakers between the
ages of 30 and 39 and those older than 50 years are significantly heavier than caretakers less than 30 years old (p= 0.05)
This pattern is also found in Season 2 and
Season 3 when the SNK test is employed.
The differences may
be related to age-specific patterns of nutrient utilization and to differences in work patters.
Gay (1982) has shown
differential work tasks for Basotho women, with younger women doing more of the heavy work, while older women perform less demanding work. When compared with the NCHS sample (Frisancho 1988), caretakers less than 20 years old (N= 10) have weights between the 5th and 50th percentiles in all three seasons, while all other age groups are between the 50th and 75th percentiles for weight. In Table 6.2., BMI (weight/height2) is presented in each season for the total sample and by age group.
The
highest BMI is found in Season 2, while the lowest BMI is found in Season 3.
Again One-way ANOVAS show highly
significant differences between age groups within each season (p= 0.001, 0.002, 0.001; for Seasons 1-3, respectively).
The SNK test reveals that caretakers over 50
years old (N=14) have higher BMI's than all other age groups throughout all three seasons (p= 0.05); also caretakers between 30 and 39.99 years have significantly higher BMI's than those less than 30 years old (p= 0.05). 198
Reproduced with permission of the copyright owner. Further reproduction prohibited without permission.
In Seasons 1 and 3, caretakers have BMI's between the 50th and 75th percentiles when compared with the NCHS sample; these indices increase to the 75th percentile in Season 2.
Caretakers between 30 and 39.99 and over 50 years
maintain BMI's over the 75th percentile in all three seasons.

Table 6.8. shows the results of regression analysis of various independent variables on dependent anthropometric measures in Season 3 (the most seasonally stressful period). Variables such as the number of household fields, number of illness episodes, number of household members, number of children less than 10 years old, and the number of agricultural activities that caretakers perform are included in the various regression equations.
Their negative
association suggests that as each one of these independent variables increases, anthropometric measures decrease (see Beta values).
These regression equations however, only
explain between 5.4 and 8.8% of the total variance, depending upon the anthropometric measure; thus their explanatory power is limited. TABLE 6.7. Correlations between seasonal caretaker nutritional status (reported as Z-scores) and socioeconomic and agricultural indicators # possess.

data by age (i.e., Fels Research Institute and NCHS growth curves).
In general, for the majority of boys and girls (45
to 55% of the total sample), absolute measures of weight (Figs. 6.10- 6.15.) fall between the 5th and 50th percentiles when compared with the NCHS sample in each of the three seasons.
Between 30 and 35% of both sexes have
weights lower than the 5th percentile, while the remainder have weights higher than the 50th percentile when compared with the U.S. sample.
This same pattern is shown when
examining absolute measures of stature (Figs. 6.16-6.21.); however, the percentage of girls falling below the NCHS 5th percentile is somewhat lower than that of boys in all three seasons.
Although there appears to be some catch-up growth
for stature between Season 1 and Season 2 for both boys and girls, by the time Season 3 comes around, more children of both sexes, are below the 5th percentile as compared to Season 2. This finding supports the pattern of stunting for children described in other populations from developing countries (Martorell and Habicht 1986).
In addition, it
reaffirms the notion that highly seasonal ecologies, which are intense and frequently dispersed, do not allow for adequate catch-up growth during the "good season(s)11 when food is in relative abundance.
These findings will be
discussed in the last section of this chapter.

While the mean number of illness episodes shows a weak inverse correlation with child nutritional status (Z-scores for weight-for-age, stature-for-age, and weight-for-stature ) in Season 3, the correlations are stronger when examining variables such as the mean number of diarrhea symptoms (e.g., fever, stomach pain, and vomiting) and the mean number of stool symptoms during diarrhea (e.g., loose stool, blood in stool, mucus in stool, large volume, very bad odor, green color) in all three seasons.
