PhD PROPOSAL
The impact of classical biological control of coconut mite on income
and food security: A stakeholders and socioeconomic analysis of
coconut production in Africa and Sri Lanka
By
Oleke, Jofrey Masahi
1.0 Introduction
The coconut palm and its fruit are regarded as one of the most important crops of the
tropics (Child 1974). Among its most important uses coconut is a food source, which
provides supplements for body fluids and minerals, and acts as an antihelminthic. The
liquid endosperm is also a media for invitro storage of semen and a growth regulator of
plants (Woodroof 1970). Copra, the dehydrated endosperm of the nut, is a source of oil
for food. Coconut oil is also used in cosmetics and pharmaceuticals. The material that
remains after the oil is pressed from copra is called oilcake and is used as animal feed
(Woodroof 1970). The coconut shell is used directly as fuel, filler and extender in the
synthesis of plastic, to make activated charcoal, household articles, and to produce
various distillation products, such as tar, woodspirit and pitch. Coir, a course fiber from
the husk of the nut, has various domestic and industrial uses. Coconut root is brewed and
used in folk medicine, for example, as a cure for dysentery (Woodroof 1970). The
possibility of utilizing the coconut palm wood on a commercial scale has been recognized
only in the last decade or so, although usage of wood from palm species has been known
by people in the villages since time immemorial. In more recent times, coconut palm
wood has been successfully utilized in a number of coconut growing countries such as the
Philippines, Indonesia, Sri Lanka, Fiji, the Tonga Islands and many others (Arancon,
1996). In Kerala state (India) coconut is the major industry. In Africa and Tanzania in
particular, poles and leaves are used for building materials and making furniture.
Coconut trees are grown in tropical countries mainly for the high oil content of the
endosperm (copra), which is widely used in both food and non-food industries. However,
a negative campaign against saturated fats in general, and the tropical oils in particular,
led to most food manufacturers abandoning coconut oil in recent years in favour of
hydrogenated polyunsaturated oils that come from the main cash crops in the US,
particularly soy, and contain trans fatty acids. Studies done on native diets high in
coconut consumption show that these populations are generally in good health, and don't
suffer as much from many of the modern diseases of western nations
(http://www.coconutoil.com/litalee.htm). Large coconut production areas, in particular,
are found along the coastal regions in the wet tropical areas of Asia in the Philippines,
1
Indonesia, India, Sri Lanka, Malaysia and Africa (see figure 1). In these countries
millions of people make a living from the coconut palm and its many products (Dam,
2002).

Although good varieties of coconuts have been known to exist in the different coconut
growing countries of the world, no serious attempts were made to collect them and study
them in detail at a representative centre with a view to classify them systematically. The
commonly known varieties includes Tall Palm, which is the ordinary or the common tall
variety of palms most extensively grown on a plantation scale in all coconut tracts of the
world. The West Coast Variety otherwise known as the ordinary or common Tall variety
is commonly grown in India. Others include Laccadive Ordinary, Laccadive Small, New
Guinea, Cochin China, and Java grown mainly in India, Sri Lanka and Indonesia (Ikisan,
2009).The East African Tall and the other a dwarf (called Pemba Red Dwarf or simply
2
Pemba Dwarf) occur everywhere along the Tanzanian and Kenyan coastal coconut
growing area, probably also in Mozambique, Madagascar and the Philippines (Kullaya, et
al, 2002).
Coconut is a tropical crop that supports the livelihoods of many people. Coconut
contributes significantly to the economy of Sri Lanka and cultivation spans about 402649
ha which accounts for 21% of agricultural lands in the country. It contributes 2% to Sri
Lanka’s GDP, 2. 2.5% to export earnings and 5% to employment. Although these
numbers are modest, coconut is an important food crop in Sri Lanka in that it provides
about 22% of the per capita calorie intake in the diet, being second only to rice paddy, the
staple food of Sri Lankas. Coconut is almost exclusively grown as a rain fed crop in Sri
Lanka. Rainfall and temperature are the important climatic factor influencing the coconut
yield (Peiris, et al 1995), and by extension on the national coconut production, on, upon
which domestic culinary consumption and processing industry depend. In the Philippines,
coconut is mainly a smallholder crop and it occupies 23% of the country's total land
devoted to agricultural use while in Indonesia coconut area represents around 26% of the
entire plantations. In Indonesia, around 95% of the country's coconut area is situated in
the islands of Sumatra, Java, Sulawesi, Kalimantan, Nusa Tenggara, and Maluku. In
India, coconuts are grown mainly along the coastal belts and some interior tracts and
more than 90% of the area under coconut is concentrated in the Southern States of
Kerala, Karnataka, Tamil Nadu and Andhra Pradesh. Kerala accounts for 55% of India's
total coconut area (Dam, 2002). While the coconut industry in Vietnam contributes to the
economic welfare of some 10 million Vietnamese, and provides direct employment to
some one million people, in Malaysia the industry plays an important role in the country's
economy providing livelihood to some 100,000 farm families or almost 10% of the
nation's farming community. In West African coast including Benin, coconut is one of
the major crops that support the livelihoods of many communities. It contributes
significantly to the income of the people depending on it. The coconut producing
countries continue to produce due to the importance of the crop as a social crop. These
countries realize the potential coconut holds in economic development and poverty
alleviation (Bashar, 2002). Along the coastal belt of Tanzania, coconut is one of the
3
important crops (Mwinjaka, 1999). It is produced in Dar es Salaam, Coast, Tanga, Lindi,
Mtwara, Zanzibar, Pemba, Mafia and inland region of Morogoro and on the shores of
Lake Nyasa, Tanganyika and Victoria. In Tanzania the population of palms was
estimated at about 25 million. About 95 percent of the coconuts are grown by small-scale
farmers while the rest are under medium and large-scale plantations (Kullaya, 1999).
Coconut is important as; the main source of income for farmers in the coastal belt of
Tanzania where 15 percent of the country’s population live (Mwinjaka, 1999). The palm
products in Tanzania are mainly fresh coconuts, copra and coconut oil. It is estimated that
of the total coconut production 40 percent is marketed as fresh coconuts and 20 percent is
processed into copra and coconut oil (Debus and Zills, 1981). Fresh coconuts are mainly
used as a source of coconut milk (“tui”) that is used for cooking purposes in most of the
households in the coconut growing areas (Magitta, 1989). Copra is processed into
coconut oil which is used for both cooking and industrial purposes – notably in soap
making (Magitta, 1989). In Zanzibar (Tanzania), coconut production constitutes a lager
part of economic activities. It became the second most important foreign exchange earner
in Zanzibar, after cloves, and it held this position for a long time (Kullaya, et al, 2002).
The coconut, like many plants is subject to attack by various pests and diseases. Often,
plants develop some defence mechanisms to local pests and diseases (Peiris, 2005). The
coreid bug, Pseudotheraptus wayi Brown (Heteroptera: Coreidae), the rhinoceros beetle,
Oryctes monoceros Oliv (Coleoptera:Scarabaeidae) and the coconut mite, Aceria
guerreronis Keifer have been identified as the major coconut pests of economic
importance. The major disease of coconut is the lethal disease (LD), which is caused by
phytoplasma. The symptoms of LD are very similar to those of Lethal Yellowing-type
disease in the Caribbean area and West Africa. They include premature nut fall, typical
blackening of the inflorescences, bronzing of progressively younger leaves, necrosis and
rot of the spear leaves and decay of the root system, in that order (Mwinjaka, 2009).
Increase in trade, tourism, transport and travel over the past century has dramatically
enhanced the spread of organisms (e.g. Wittenberg & Cock, 2001). As a result, biological
invasions by non-indigenous species constitute a leading threat to natural ecosystems and
4
biodiversity (Pimentel, 2002). Bioinvasions involving exotic pests are also an undesirable
element of the globalization of agriculture. Aceria guerreronis Keifer (Coconut mite) is
one of the exotic pests that pose a threat to the coconut industry. Accordingly, substantial
efforts to eradicate or control invasive mite have resulted in high economic costs
(Pimentel, 2000). A number of control measures mostly involving aerial application and
root feeding of chemical pesticides have been recommended, but a solution to eradicate
the mite menace is yet to be evolved. In India and Sri Lanka adoption of phytosanitary
measures in coconut gardens such as cleaning the crown of the palm, keeping the
plantation clean and burning of all immature nuts fallen due to mite infestation, spraying
biopesticides on the bunches and following palm health care practices have been the
traditional ways to control the mites (http://coconutboard.nic.in/protect1.htm).
Intercropping with the multipurpose leguminous tree, Gliricidia sepium
has been recommended by the Coconut Research Institute (CRI) in Sri
Lanka to control the mites and is well practiced by the farmers.
Intercropping of pineapple has also been successful in the western part
of the Jaffna peninsula. Mixed cropping systems, as well as those with
good ground sanitation, showed low mite infestations, except for
mixed coconut gardens with banana, which recorded the highest mite
infestation. Banana uses large amounts of potassium, the lack of which
in coconut may affect its water retention capacity. Mixing banana with
coconut is therefore not advised (CRI, 2008).
Effective control strategies generally require knowledge of the pest in their introduced
and native ranges (Roderick & Navajas, 2003) as is illustrated by the invasive spread of
the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), which
attacks coconut. For this species, a series of studies have used molecular data to
document the spread of the insect in its home range in sub-Saharan Africa (White &
Elson-Harris, 1992) to reach a nearly global distribution in less than 200 years (Fimiani,
1989). Besides describing the invasion pathways of the species, knowledge of the genetic
structure of fruit fly populations has helped to design control strategies including
5
quarantine and sterile insect release (Bohonak et al., 2001; Bonizzoni et al., 2001;
Gasperi et al., 2002; Baliraine et al., 2003). Similar knowledge has been used to study
coconut mite and design strategy to control it
The coconut mite, attacks young fruits of the coconut palm, to which it is almost
exclusively confined. The mites are small, with the largest stage around 250 µm in
length, but they often build up extremely large and dense populations, in which case their
feeding causes scarring and distortion of the fruits, and may cause premature fruit drop
(Moore & Howard, 1996). In fact, it is one of the worst arthropod pests of coconut palm
mostly spread by wind, whether grown as a crop tree or as an ornamental, and is the only
eriophyid mite that is a serious pest of coconut palm. It is distributed in many tropical
countries where coconuts grow. It is controversial whether it is native to the Eastern or
Western Hemisphere (UFIFAS, 2009).
1.1 Problem Statement and Justification
Aceria guerreronis has been reported to cause great losses to farmers and the coconut in-
dustry as whole as it kills coconut seedlings by feeding on growing tips (Aquino & Ar-
ruda, 1967). The survey carried out by the CRI in Sri Lanka revealed that the percentages
of mite infested nuts in the Anuradhapura, Pollonnaruwa, Rajangane, Puttalam and Kur-
unegala are 94.4%, 94.5%,90.5%, 81.1% and 69.8% respectively with a mean of 77.9 in
2001. In this study harvested nuts were monitored for one year at monthly intervals and
grouped into ‘mite free (undamaged)’ and ‘mite infested (damaged)’ nuts (Peiris, 2002).
Reductions in copra yield have been variable from 15–40% (Herna´ndez Roque, 1977;
Julia & Mariau, 1979; Muthiah & Bhaskaran, 2000; Nair & Koshy, 2000; Seguni, 2002).
Losses due to extensive premature dropping of fruits have been reported from 60% in
Colombia (Zuluaga & Sa´ nchez, 1971); 70% in Venezuela (Doreste, 1968), and 10–
100% (average 21%) in Tanzania (Seguni, 2002).
For communities whose livelihoods depend on coconut, a mite infestation poses a threat
to their life. Coconut grower is affected if the nuts are small or rejected due to mite
damaged. In some serious cases of mite infestation, all nuts may drop causing losses to
6
farmers income. Generally due to damage on coconut caused by mites; farmers usually
harvest small sized nuts. Small sized nuts fetch a lower price or are rejected causing loss
to growers. Peiris (2002) estimated loss of income for coconut growers in Sri Lanka to be
7% and 43% caused by rejected nuts and small sized nuts respectively. The study also
estimated the impacts of mites on the milling industries. It was found that de-husk weight
of a mite free large normal nut and mite infested large normal nut is 0.764 and 0.665 kg
resulting 13% loss while the percentage of loss in de-husk weight of small size normal
nut is 10.6%. In Tanzania, losses of growers income due to coconut mite is estimated to
be about 30-50% (Seguni, 2008). Despite its effects to the income, coconut mite also
poses a threat of food insecurity to the households growing coconut since coconut
contributes significantly to the their livelihoods.
Strategies to control coconut mite involving both biological control and quarantine
require knowledge of the ancestral localities and plant hosts of the mite. However, the
origin of the coconut mite is unknown. Almost simultaneously with its original
description in the 1960s, the mite was reported in Africa beginning with Gulf of Guinea
Islands in 1966, Benin in 1967, and in Tanzania during the 1980s. Several studies on
coconut mites have been conducted in the areas affected by the arthropod. In Brazil,
Benin and Tanzania a study was conducted to assess coconut mite abundance and
damage to coconut – and the associated predator fauna - in (Lawson et al. manuscript
submitted; Negloh et al. manuscript in prep.). In all of these localities, however, coconut
mite infestations were heavy, implying that the effects of these pests were huge.
Similar work had been conducted independently in Sri Lanka (Fernando et al. 2003).
Evaluation of the data collected to date indicates that coconut mite abundance and
damage to coconut are far less in Brazil than in Africa and Sri Lanka, and that the
predator fauna associated with coconut mite in Brazil is richer than what is found
elsewhere. In Tanzania the coconut mite has only recently been recognised as a serious
pest of coconut (Varela, 1992; Meena, 1996). During extensive surveys in Tanzania in
1992 and 1996 (Varela, 1992; Meena, 1996) the coconut mite was observed in all
coconut growing regions of Tanzania affecting all or most coconut varieties, but there
7
were site differences in severity of infestation. The southern regions of Mtwara and Lindi
appeared to be more seriously affected and were thought to be due to the unimodal
rainfall pattern (Varela, 1992). However, these findings have not been proved by
subsequent surveys.
In attempt to control coconut mite, predatory mites found beneath the coconut perianth in
Florida and observed to prey on coconut mites include Amblyseius largoensis Muma,
Neoseiulus mumai Denmark, and N. paspalivorus DeLeon. In Puerto Rico, Bdella
distincta Baker and Bablock preyed on coconut mite and on Steneotarsonemus furcatus
(DeLeon) in the same habitat. In both of these localities, however, coconut mite
infestations were heavy, implying that the effects of these predators were insignificant.
The fungus, Hirsutella thomsonii (Fisher), which is widely distributed and known to
attack various species of mites, has been isolated from coconut mites in various countries,
as has H. nodulosa Petch in Cuba. Control of several species of mites with fungus has
been developed and applied, but success has often depended greatly on environmental
conditions. In general, these efforts have been most successful under humid conditions
favouring the development of the fungi (UFIFAS, 2009).
While previous efforts have identified the natural enemy fauna associated with coconut in
northern and northeastern Brazil, very little has been done to explore for natural enemies
of coconut mite in other countries in South and Central America (e.g., Mexico,
Venezuela, and Colombia). These are countries where the coconut mite is present but
there are no reports of serious damage to coconut, making them potential candidate for
foreign exploration. The identification and introduction of potential natural enemies of
coconut mite, and understanding their diversity and the ecological factors that affect
plant-pest-predator, and predator-predator interactions and their effects on coconut mite
control are of tremendous scientific interest. This study therefore becomes a part of a big
program, that will search for and characterize the biology and ecology of natural enemies
of coconut mite in regions in the Americas that have not been explored, and conduct
experimental releases in Africa and Sri Lanka of one known or newly identified natural
enemy and simultaneously determining with molecular tools and cross-breeding
8
experiments whether Brazilian populations of predator species associated with coconut
mite are biologically similar to conspecifics found in Africa and Sri Lanka. The searches
will be to understand interspecific interactions among co-occurring natural enemy species
and their impact on coconut mite. Experiments will also help in understanding plant
factors that affect the susceptibility of coconut mite to predation and predator dispersal,
with the aim of designing interventions that could enhance biological control. This study
will include stakeholder surveys while production and marketing data will be used in
socioeconomic analyses to determine the effect of biological control interventions on
peoples’ livelihoods. The stakeholders include producers, consumers, suppliers,
vendors/marketers and policy makers in each target country. The baseline survey will set
the benchmark for assessing the effects of biological control. The program is likely to
contribute substantially to our fundamental understanding of the factors that affect the
success of biological control – of one of the most challenging pests - while simultane-
ously improving livelihoods of people who depend on coconut
The present study is therefore an attempt to conduct stakeholder analysis to determine
their perceptions on the performance of coconut sub-sector and constraints facing the
industry, particularly focusing on the impact of attacks by mites on the coconut yields
and survival. Informal and formal interviews with stakeholders will help understand their
perception on the effects of the mite attacks in their livelihoods. The data on income
distribution will be used to assess the impacts of the biological control on gender equity.
In the baseline survey, fresh coconut value chain analysis will be carried out. The
farmers, merchants and consumers will be surveyed to get their views on the production
and marketing of the coconut. The study will further undertake a benefit/cost analysis of
controlling the mites in order to improve the performance of the sub-sector and its
contribution to poverty reduction. The livelihoods of more than 15 million people in
Benin, Siri Lanka and Tanzania are at stake if the mite is not controlled. Hence seeking
to understand the mite’s fauna and migratory pattern is an important step towards finding
cost effective control mechanism. The study will also determine consumer willingness to
pay for products produced under biological control of coconut mites. The consumer
preference study is important due to increased concern on environmental and health
9
issues related to food products. Thus the study will pursue the following specific
objectives;
1.2 Objectives
(i) To assess the perception of the stakeholders (farmers, customers, merchants)
regarding the performance (constraints and opportunities) for coconut value
chain.
(ii) To establish indicators and benchmark for assessing the impacts of biological
control method
(iii) To take inventory of various coconut based cropping systems and characterize
and rank them according to economic performance.
(iv) To compare cost and benefit of biological control of coconut mite to those of
other pest control methods.
(v) To determine the contribution of biological control of coconut mites (other
pests) to food security, gender equity and income.
(vi) To determine consumers’ relative preference for coconut products produced
under biological control of coconut mite and those produced with pesticide.
1.3 Research Questions/ Hypotheses
On the basis of the specific objectives one and three, the following research questions
will have to be answered;
i) What are the constraints and opportunities in the coconut value chain?
ii) What are existing coconut cropping systems?
iii) What are the characteristics of each coconut cropping systems?
On the basis of the specific objectives four, five and six hypotheses will be tested as
follows
(i) The first null hypothesis specifies that biological control of coconut mite is
less profitable than other pest control methods
10
-The alternative hypothesis specifies that biological control of coconut mite is
more profitable than pest control methods
(ii) There second null hypothesis specifies that there is no significant contribution
of biological control of coconut mite to food security, gender equity and
income of the coconut producers.
-The alternative hypothesis specifies that the biological control of coconut
mite method has a significant contribution to food security, gender equity and
income.
(iii) The null hypothesis specifies that consumers prefer coconut products produced
through biological control of coconut mite to those products produced using
pesticides.
-Alternate hypothesis specifies that consumers prefer coconut products
produced using pesticides to those produced through biological control of
coconut mite
2.0. Research Methodology
2.1. Study Areas
The study will cover different geographic regions where the mite is currently reported,
including several of the main coconut production regions in the Asia (Sri Lanka) and
Africa (Tanzania and Benin Republic in West Africa).
2.2. Sampling Strategy
In this study, first, baseline study will carried out in the three selected countries. The sur-
vey will be carried to obtain the baseline information that will be used to assess the im-
pacts of the introduction of biological control of coconut mites in the livelihood of grow-
ing farmers. The importance of coconut production in the areas is the basis for considera-
tion for sampling approach in this survey. Discussions will be held with the research in-
stitutes in the respective countries to purposively obtain the sub-countries and villages
where coconut is important. With the help of local extension staff, a list of wards/sub-
11
countries and villages will be developed for all of the villages highly producing coconut.
All the villages will be put together and 15 will randomly be selected. The list of house-
holds will be obtained from village register books and 450 households will comprise a
sample for all three countries. A survey will also include 90 randomly selected coconut
wholesalers and 90 retailers from purposively selected buying points (Local market/Mar-
ket centers). The list of both wholesalers and retailers will be obtained from market cen-
ter authorities. Coconut consumer intercept survey will be carried out in the market cen-
ters. A systematic sampling will be employed to get 150 coconut consumers in the three
countries. Information regarding coconut processor will be obtained from records main-
tained by coconut research institutes in the targeted countries. From a list prepared,
90 coconut processors will be involved in this study.
Secondly, the consumer intercept survey will be carried out in the third
year of the study to determine the consumer willingness to pay for co-
conut products produced under biological control of coconut mite. Fol-
lowing field tests of the survey instrument, consumers will be ap-
proached at direct-sale outlets such as farmers’ markets, roadside pro-
duce stands and malls. A systematic sampling will be employed in
which 210 from randomly selected respondents will constitute a sam-
ple in all the selected countries.
In the third and fourth year of the study, cost and benefit analysis of
the biological control of coconut mite and the impact studies will be
done respectively. The sampling approach described above for base-
line survey will be adopted.
2.3. Data Collection Methods
Informal group interviews and key informant surveys will be organized for producers,
consumers, suppliers, vendors/marketers and policy makers in each target country. Using
structured questionnaires, information collected will include socio-demographic and
economic characteristics of farms and communities involved; coconut production
12
technologies and practices available and used by producers; current and potential impact
of coconut on income; and trends in coconut production and income distribution. Other
information will include new crop protection practices and mainly data relative to
biological control and related yield and improved quality (oil, copra, etc) and coconut
cropping system. Fresh coconut value chain analysis will be carried out for producers,
wholesalers, retailers and processors. The study will assess the cost and benefit of the
biological control and other new techniques and return on investment in biological
control through increased production and improved quality of coconut as a result of
biological control of coconut mite. Assessment of consumer preferences will be carried-
out for consumers’ willingness to pay for coconut products produced under biological
control of coconut mite and those produced with chemical pesticide.
2.4. Questionnaire Pre-testing
For a baseline survey, the pre-testing of questionnaires will involve coconut farmers,
coconut wholesalers and retailers, consumers and processors. The pre-testing of
questionnaire will be done by interviewing 20 coconut farmers in Mkuranga, District,
Tanzania while pre-testing of questionnaires for coconut wholesalers and retailers,
consumers and processors will be done by interviewing 10 respondents each. The pre-
testing will be done in Dar es Salaam, Tanzania. Necessary corrections will be made to
the questionnaires before data collection. The pre-testing of questionnaire for cost-
benefit, consumers’ preference and impacts studies will be planned after the baseline
study is complete in the second third and fourth years of the study.
2.5. Data analysis
Responses from the interview will be coded and summarized using excel. The descriptive
analyses will involve computation of statistical means, standard deviations, graphs and
frequency distribution. Quantitative analyses will be performed using Statistical Package
for Social Sciences (SPSS for Window, 12.5). Cross-tabulations involving Chi-Square
tests will also be employed in testing association between variables. A logit regression
model will be estimated to assess the effects of socio-economic variables on the
13
dependent variables. Estimation of parameter in the models (MLE) will be performed
using econometric soft ware LIMDEP (Green, 2002).
2.5.1. Analysis of Coconut Value Chain
Estimates of marketing margins and marketing efficiency will be obtained using the
formula given by Kohls, (1985). According to Kohls (1985), marketing margin equals the
difference between what the consumer pays and the farm gate price per unit of the
coconut produce. Based on this formula and on the assumption that wholesalers buy
directly from the farmers, while the retailers buy directly from the wholesalers, it then
follows that wholesalers’ margin equals wholesalers’ selling price per unit minus
farmers’ selling price per unit. Also, retailers’ margin equals retailers’ selling price per
unit minus wholesalers’ selling price per unit. The net margin accruing to the wholesaler
or the retailer is the difference between the market margin and the marketing costs.
Marketing cost is the sum of transport cost, storage cost, labour cost and other costs.
Marketing efficiency is then calculated using the formula given by Olukosi and Isitor
(1990). The formula is as specified below;
In other words,
To calculate market margin and market efficiency, the average prices of coconut is used
as given by the respondents in the various markets. Marketing Margin analysis can be
represented as
Where;MM = Marketing Margin between market level i and market level i – 1.Pi = Price at market level i Pi -1 = Price at market level i -1 Margin percentage is expressed on the basis of buying price. That is
2.5.2. Gross Margin Analysis
14
Gross margin is the difference between total revenue of coconut and the variable cost
attributed to it as shown in equation (5) below.
Where;
GM = Average Gross margin (US$/ha)
TR = Average total Revenue (US$/ha)
TVC = Average Total Variable costs (US$/ha).Thus we can estimate producer share as described in the next section
2.5.3. Producer Share
This the ratio of producer price to consumer price (retail price) depending on the level of
marketing chain. It will be calculated by;
Where:
Ps =Producers’ share
Px =Producers Price
Pr =Retail Price
MM=Market Margin
2.5. 4. Cost and Benefit Analysis
In this study of potential cost and benefit of biological control of coconut mite control,
primary data will be gathered through structured questionnaire while secondary data will
be extracted from project reports. This analysis will focus on valuing crop damage in
terms of quantity and quality resulting from varying levels of pest infestation (yield
responses to insect damage), the efficacy of biological control agents at different levels of
infestation, the resource requirements of the biological control method such as labor and
equipment for application (egg cards, distribution boxes, etc.), the quantity of biological
control agents, and the labor required to determine the need for field monitoring, the
effects in subsequent time periods on infestation, yield and other pest controls needed, the
interactive relationships among biological control agents and factors such as soil fertility,
crop varieties and weather.
15
Other data needed will include the prices of product and inputs used in the production of
the crop. Since coconut is in competition with other enterprises on the farm, costs and re-
turns associated with the competitive crops are also needed. The cost-benefit ratios are
based on a brief but comprehensive survey of data sources, but nevertheless are approxi-
mations within ranged values. Because of the permanent nature of biological control, the
net benefits () [i.e., benefit (B) - costs (C)] corrected for the present value of money us-
ing the discount rate (1+)-1 accrue over t years (i = 1... t) will be given as.
Where;
= Summation sign = Interest rate of price of money.
Gross revenue (B) to the coconut production is given as
Where; P= Price of output, Y= Maximum possible yield D =Damage rate per pest N and E are the efficacy of the biological control
In reality, D is a function of N (i.e., D (N (1-E))), but for simplicity we assume that D is
a constant. In fact, the benefit of biological control for the ith year is B i = PDNiE, and in
the extreme may equal PY.
In evaluating the effectiveness of chemical control or biological release of natural ene-
mies, the balance of revenues (B(X)) = the value of the increase in yield attributable to
using X units of the control measure (e.g., pesticide or biological control) minus the out-
of-pocket cost (C(X)) of causing X units of the control measure. Only infrequently are
the social costs (S(X)) associated with the control measure included. For and biological
control, S(X) is usually zero. The benefit function is usually assumed to be concave from
below and the cost per unit of X constant. The net benefit (II) function is thus given as.
16
Thus the optimal solution to this function occurs when
It is important to note that the social or external costs of pesticides in terms of pollution,
health and environmental effects are seldom included in the grower's calculations because
there is no economic incentive to do so.
With naturally occurring biological control and economically viable classical biological
control (BC), the costs of other pest control tactics and social costs often become zero,
and the whole of society obtains the maximum benefits, the natural and biological con-
trols supplant other methods of control and are assumed to solve the problem perma-
nently. In such cases biological control should be favored as the equation for profit be-
comes;
2.5.5. Consumers’ Willingness to Pay (WTP)
The purpose of this analysis is to ascertain first consumers’ willingness to pay for se-
lected coconut products and how the demographics may influence willingness to pay for
coconut products produced under biological control of coconut mite. The specific prod-
ucts to be examined will include………………..
Respondents will be presented with label that would appear on or near the products. The
label indicates whether the product has been made of coconut produced under biological
control of coconut mite or pesticides. Then the respondents will be asked a question re-
garding their opinion of willingness to pay for products produced under biological control
of coconut mites. Respondents can answer that they “support biological control and
would pay a higher price for product under biological control”, “support biological con-
trol of coconut mites but not if it requires paying a higher price for derivative product ”,
or “do not support biological control products regardless of whether it costs me any-
17
thing”. Those responding that they would pay more for biological control products will
be then asked a series of questions regarding pricing of specific products. Prior to this se-
ries of questions, the respondents will be presented with a reminder that this is a hypo-
thetical situation and of their ability to pay for the products.
Two pictures of coconut products (to be determined) will then be presented to the respon-
dents. The respondents will be reminded that these are simply examples of coconut prod-
ucts, and they might wish to purchase a product of a different style, color, or type of co-
conut. In the case of each product, two identical pictures will be shown so that the two
products are identical in all attributes except for sources. Dimensions for each product
will also be provided, as will the price for the coconut products produced under pesticide
control. These prices will be based on prices for representative products in the local mar-
ket area. Respondents are then asked how much more they would be willing to pay for a
product that was produced under biological control. Demographic questions will con-
clude the survey.
Willingness-to-pay measurements are grounded in utility theory. Hanemann (1991) out-
lines the theoretical underpinnings as a utility maximization problem subject to a budget
constraint. The consumer chooses the level of the good X that maximizes utility, produc-
ing the traditional Marshallian demand curve X (p, y, q), where p is market price, y is in-
come and q, is the quality of the good, fixed exogenously. The resulting indirect utility
function is V (p, y, q). Identifying a change in a good’s quality from q0 to q1, the mea-
surement of value is
Where WTP is the amount the consumer would be willing to pay for the improved qual-
ity, maintaining constant utility. The estimate is shown more directly using the dual prob-
lem: expenditure minimization constrained by a given utility level (Lusk 2004). The dual
produces the Hicksian demand curve X (p, U, q) and indirect expenditure function M (p,
U, q) so that
Where U is a constant utility level
18
The random utility model (RUM) is used to analyze choices and estimate WTP. When re-
spondents are asked to make a choice of whether or not to pay a given dollar amount, a
positive response is interpreted as their WTP. In order to find the central tendency of
WTP from a sample, the positive responses are fitted to a probability function. This is
modeled as the probability that the utility derived from the good associated with that
choice is greater than the alternative,
Where V is the indirect utility and is the error term.
Estimates of WTP are based on the mid-point of this function, i.e. the point at which the
probability of a positive response is 0.5. The most basic version of this model includes
only the socioeconomic attributes of respondents as variables.
This is the model used in contingent valuation choice analysis. Lancaster (1966) builds
the conceptual framework for conjoint analysis by clarifying that utility is gained from
the characteristics of a good rather than the good itself. Characteristics are objective qual-
ities of a good while attributes, on the other hand, are what the characteristics represent,
and are the real source of an individual’s utility. Lancaster maintained that utility should
be a function of characteristics rather than attributes as the former are measurable, so that,
Where t represents the characteristics of a good X, based on the consumption technology
matrix B (i.e. the amounts of each characteristic which are predetermined in each good).
Louviere, Hensher and Swait (2000) further refine these distinctions, making utility a
function of consumption services. Each characteristic of a good is associated with a con-
sumption service which it provides. Moreover, they suggest that utility maximization is
19
based on expected services of a good because consumers do not have complete informa-
tion. In practice, the model forces a one-to-one correlation between services and charac-
teristics. However, these theoretical distinctions are helpful in conceptualizing character-
istics as signals that communicate value. Conjoint analysis proceeds with a good that is
decomposed according to the Lancastrian model and measures its part-worth values is
shown below.
Where Vij denotes the individual’s indirect utility from choosing product j and ij is an error term.
The part worth utility is represented in the following relationship
Where Vij denotes the individual’s indirect utility from choosing product j; xj is a vector
of product attributes level j’s; pj is price for product j; is a conformable vector of coef-
ficients and is a conformable coefficient to be estimated; and ij is an error term.
This simple additive linear function produces the main effects of our model. These effects
indicate how utility is affected by the level of the attribute when it is isolated from all
other attributes. Higher order effects indicate whether utility is also affected when two at-
tributes are presented in tandem (Louviere, et al 2000). We incorporate combinations of
attributes by interacting product attribute levels, so that,
Where cij is a vector of combination effects from product attribute level i's interacted
with product attribute level j's; and is a conformable vector of coefficients to be esti-
mated.
The final dimension to our model is that of preference variation among the population. In
order to account for different preferences among various sub-populations we incorporate
socioeconomic characteristics through interaction terms with the attribute level variables,
so that,
20
Where Sij is a vector of socioeconomic variables i’s interacted with product attribute level
j’s; and is a conformable vector of coefficients to be estimated. Now that we have the
utility function defined, we can model the choice as the relative differences in utility. The
difference between product A and product B for individual i is,
Where dViAB = the utility difference between product A product B. Thus the model above can be represented.
The signs on parameters indicate the hypothesized relationship. The parameters are esti-
mated with the maximum likelihood procedure for a binary probit model with the Limdep
statistical package.
2.5.6. Household Food Security
Food security indicators such food stock and number of meals eaten daily within a house-
hold will be summarized. The Pearson Correlation Coefficient will then be applied to de-
termine the relationship between coconut production indicators and food security indica-
tors.
Using the food balance sheet model, the total food available to the household for con-
sumption will be estimated as follows:
Total food available for household consumption =Total food produced + Total food
purchased and food donations-Total food sold, wasted and given out as food losses.
That is;
, at time t = a year…………………………………. (25)
Where; Fy is total food available for household consumption
21
Fo is total food output (Produced)Fp is total food purchaseFd is total food donationsFs is total food sold outFt is total depleted food (food wasted)
The household food available for consumption is commonly believed to be dependent of
the household factors of production such as land household food expenditure as well as
household characteristics and socio-economic characteristics, access to market, credit,
land, size, extension services, livestock diversity, education, household size and age. This
relationship will be shown as;
Where; Y represents household food availability for consumptions measured in calories Pf represents household factors of production such as land Hex represents household food expenditure.
Thus the equation for estimation will be as written below;
Where; X1-X5 = socio-economic factors while other variables are as previously defined
2.6. Budget and Source of Funds
The baseline survey is estimated to cost 26477 USD (see appendix 7 for detail). The
budget for cost-benefit, consumer preference and impact studies is estimate to be 26500
USD. A total of 52977 USD will be requested from the University of Amsterdam (the
Netherlands) in collaboration with IITA to finance the study.
