Visiting my village's rice fields
Data collection for water and sanitation projects
My village has a number of wells, in various stages of decomposition. Some have enclosures around them, most do not. These wells are vulnerable to contaminants of all kinds, ranging from organic (bacteria, animal droppings) to inorganic (dust, sand, acid rain maybe). There's a good chance that some of the more common village illnesses, such as diarrhea, are due to unclean water.
My work partner and I spent my first couple of months in village sending out letters to different NGO's specializing in water and sanitation, in the hopes of receiving funding for a project. We're not sure yet what exactly the project will consist of. Depending on the level of contamination, it might be a simple matter of installing metal covers on the wells. Other more complex options include building robinets and waterpumps. Everyone wants a robinet, with good reason: pulling water is hard! But people also want the robinets because it's a status symbol: look how modern we are! Thing is, robinets and pumps require a substantial amount of maintenance and financial investment over a long period of time. I'm not convinced that my villagers have that level of investment at this point. In any case, these projects will involve causeries and trainings on how to treat drinking water for safe consumption. These behavior change activities are the most difficult, but they often have the greatest impact on overall health once they are adopted.
Some of the NGO's asked for data and pictures of available water structures. On September 15th and 16th, my work partner and I visited all the wells in all three villages. We measured the depth of each well and the depth of the water, took pictures, and took notes pertaining to overall cleanliness. We visited 15 wells in all!
| A well in Dassilami |
Here's a disturbing case study. Unfortunately, this is well I draw water from every morning. Early that week, I'd been told that the inside of the well had "fallen", or "collapsed"(translating from Mandinka is hard). I'm not sure what happened, but it does look like the bottom half of the well has lost its outer layer. For a while, we all had to go to another well to fetch water, which was way too far away--if you're lugging two 20 litter buckets full of water. So while the well was in disuse, here's what my work partner and I found:
| Terrifying. |
To be continued...
Training on Malnutrition Screenings
For three days in September, I participated in a "formation" facilitated by the ICP in Karang and a USAID agent.
The target audience of malnutrition screenings, broadly speaking, is children under the age of 5; they are most likely to die of malnutrition-related complications, and to suffer from developmental delays later on in their lives.
The Senegalese government promotes two kinds of activities designed to identify signs of malnutrition in the field.
The first, "peusées", targets children between 0 and 23 months. Health relays use a Salter scale to weigh babies once a month to make sure that they are gaining enough weight as they grow older. In the field, health relays have a table showing age correlated to healthy target weights, so that they can see if a child is within a healthy range.
The second kind of activity is called "dépistage", and should take place once every 3 months. It targets children between 6 and 59 months. Health relays use a "centrisouple" to measure a child's left MUAC (Mid-Upper Arm Circumference). The resulting number, in centimeters, corresponds to a color on the band: green indicates a normal circumference, yellow suggests moderate malnutrition, and red severe malnutrition.
You probably realize that neither of these methods are particularly precise. The point is to monitor children over time, identify problems, offer dietary advice, and refer the most severe cases to the health post.
Most kids in Same were healthy, but one little girl named Awa turned out to be severely malnourished. Especially when compared to her twin, a perfectly normal chubby 2 year old. Awa looked like an emaciated 6 month old, not yet walking and refusing her mother's breast. This little girl was promptly referred to the health post in Karang.
At the health post, children with moderate and severe malnutrition are given calorie-rich nutritional supplements, PlumpySup and PlumpyNut, respectively. Each child gets a certain quantity of packets depending on the amount of weight they have to gain, over a number of weeks. They are asked to return periodically to the health post so that the ICP can monitor weight gain. These methods don't always work out so well, by the way. I often so my 7 year old sister sucking on a PlumpySup not her own, because kids share the packets between themselves. And most patients don't return to the health post after their initial visit, so we end up loosing track of them.
Back in the field: dépistage and/or pesées. If a child doesn't seem to gaining enough weight, the health relays make enquiries about his or her diet, and make suggestions on how to improve it.
In Senegal, we run against some cultural obstacles to proper child nutrition. First, people eat family-style around a large metal bowl; the most nutrient-dense food items are placed in the center of the bowl. It is generally considered rude for children to reach for these foods themselves. Instead, a well-behaved child should wait for his or her mother to parcel out these items to him. Second, nutrient-dense foods--like meat--are usually only affordable in small quantities, so there's not much to go around. Finally, adults alway eat the best foods first.
(Short anecdote: soon after I arrived in village, I was gifted with a live chicken. It was so fat that everyone in my family ate his fill, "even the children" said my mother. Unfortunately, it is a rare thing for a child to fill up on chicken. Instead, they tend to eat very carb heavy meals, largely lacking in any kind of nutrient.)
So for example, a health relay might encourage a mother to feed her child more protein and fat rich meals. Some locally available foods include eggs, cow peas, moringa leaf, palm oil (usually enriched in Vitamin A). They might also suggest women let children select their own foods from the bowl.
More on this later.

Baseline Surveys and Barriers to Change Analysis
Behavior change is a fundamental part of our work as Peace Corps volunteers. It’s also the most difficult. Try changing your own habits, let alone those of an entire Mandinka village. Behavior change is also the least glamorous aspect of the job. Infrastructure projects, for instance, yield tangible and concrete results. Behavior change is harder to measure, and it’s always a work in progress.
My aim is to replicate the baseline survey that Venchele designed and conducted between November 2012 and January 2013. I’m hoping that doing so will allow me compare and contrast the results, so as to ascertain any progresses or setbacks. The survey is intended to yield data on a wide array of subjects, including current mosquito net usage, basic WASH knowledge, and recognition of common child illness’ symptoms among community members.
Many of these areas of intervention are associated with indicators in our community health project framework. Peace Corps Senegal is expected to help 880 health service providers increase their capacity to implement malaria prevention and treatment activities by 2018. One of the tools we have to measure our progress is indicator HE170, defined as the “Number of individuals who slept under an Insecticide Treated Net the previous night”.
The resulting data will have to be interpreted carefully. If I see that the number of people who slept under a mosquito net decreased between 2012 and 2014, then I’ll have to find out why. Is it because I conducted the study during the dry season instead, when people do not perceive mosquitoes to be prevalent enough to warrant sleeping under a net every night? Or could it be that the village population is growing and that no additional nets were distributed? This is when a barrier analysis questionnaire comes in handy. Identifying the barriers to behavior change will enable me to design activities and identify resources to effectively remove or undermine those barriers.
Our tools are based on the health belief model, which tries to predict and explain people’s health behaviors. It speculates that an individual will engage in a health-related behavior if he or she thinks that a specific illness can be avoided, believes that the behavior will help him avoid that illness, AND is confident that he/she can successfully carry out the behavior.
For example, a person will likely to repair the holes in his mosquito net if he believes that malaria can be avoided, thinks that repairing the holes in the net will help him avoid malaria, and is confident that he/she can repair the holes in the net.
The health belief model is predicated on the understanding that behaviors/actions follow from perceptions rather than objective truths. Formative research is a crucial aspect of the work, because it can help us understand why individuals are not engaging in certain health-related behaviors. We have to get a sense of what our communities believe to be true. For example: if they don’t think that repairing their mosquito net will help protect them from malaria, then they won’t repair their nets even if you teach them how.
The health-belief model is comprised of a series of determinants, each associated with a list of possible questions designed to assess barriers to behavior change. The following chart is intended to serve as a guide:

Technical Training: WASH (Water, Sanitation, and Hygiene) Infrastructure
Clean water is defined as
properly disinfected and stored waters that is free from E. coli bacteria.
Living in Senegal has made me realize just how precious clean water is,
especially when you have to carry gallons and gallons of it in a baignoire
precariously balanced on your head.
There are many types of
available water sources in Senegal; these primarily include forages, wells,
pumps, boreholes, rainwater, and robinets. Each has its own advantages and
disadvantages. For example, water pumps don’t require forage, they can be
sourced to a shallow water shelf, and they are covered—which decreases risk of
contamination. However, they can be expensive to built, expensive and
complicated to maintain, and require NGO involvement for design/construction. Many
volunteers build some kind of water source infrastructure during their service,
and it’s up to them to figure out which type is best suited to their community.
Quick step back: it’s
especially important to conduct surveys in the community to ascertain need
before starting such a big infrastructure project. Many people in my community
have asked me to install robinets in the village. While I have not yet
conducted surveys, I’m not convinced that they really “need” robinets, or that
it’s the best option for my community. Not only are they expensive to build and
maintain over time, they also require community members to pay for each gallon
of water used. I think it might be more of a status symbol.
According to Venchele’s base
line surveys, clean water access is an important issue in Dassilami Soce. A
full 40% of individuals do not have access to clean water, which may explain
the high rates of diarrhea and skin infections in village, especially among
children. I’m still not sure exactly why these water sources are unclean,
because the sources of contamination are unspecified. I have no doubt that well
covers would help protect the water from contamination. During VV, Venchele
mentioned that acid rain was a probably contaminant during the rainy season,
which also coincides with increased rates of diarrhea and skin infections. In
Saroudia and Boutilimite, I was told that some of the wells do not yield good
or “sweet” water. This water is used only for washing laundry, not for drinking
or cooking. I’m still not sure if this means it doesn't taste good, or if it’s
salty, or if it’s otherwise contaminated.
| My nearest well in village. |
So just because these are
many possible options available to the Senegalese people does not necessarily
mean that it’s good quality and healthful water.
And even when it is good
water, it often needs to be treated for turbidity, parasites, and/or bacteria.
Common methods include prefiltering, chlorinating, or boiling. I can tell you
straight off the bat that my villagers do none of the above with their drinking
water.
Once it’s been treated, it
needs to be safely stored in a container with a tight-fitting lid. Even well
stored and treated water is only considered safe for a small length of time:
for instance, boiled water is considered safe for 24h. After that, it has to be
treated again.
Latrine projects are also a
popular project among Peace Corps volunteers. I have friends who have only one
latrine in their village—namely, their own personal latrine. Their villagers go
into the bush to relieve themselves.
| A typical village latrine: what I'm working with |
| The case de sante's latrine: what we might build in village.... |
![]() |
| ...with its next door douche |
There are many different
types of latrines, but Peace Corps promotes a few in particular. The simple
latrine has a square or circular pit, with a hole for defecation and some kind
of shelter. The VIP-ventilated improved pit is a simple latrine with a vent
pipe and fly screen to minimize pest and odor. Double vault/pit compost
latrines have two pits built side by side. When the first pit is full, another
shelter and hole is built over the second pit. The waste in the first pit is
slowly composed over the next 2 years, and can be used as fertilizer in the
fields. The offset privy’s pit is built at an angle from the actual latrine
shelter and defecation hole. A pipe with pour flush allows waste to travel from
the defecation hole to the pit. It allows for easier waste removal, and
minimizes pests/odors.
Choosing
a good location is pretty crucial. When building a latrine, you have to make
sure it’s at least 2m above the wet seasons water table, at least 15m away from
the nearest water source, and at least 6m away from the nearest house/compound.
If you build the latrines in the middle of a public space, people may not want
to use it. If you build it under trees, it might start to stink.
Here’s
how one would go about building latrines:
·
Contact the
nearest post de santé and its Hygiene and Sanitation Committee to tell them
about your project and include them as needed
·
Consider asking
an NGO or other organization for assistance
·
Identify the
best kind of latrine for your village
·
Determine the
kind of community participation involved. Many NGO’s and programs require
community members to contribute some funds or manual labor. You can also write
a grant, and get funded through Peace Corps
·
Insist that each
family receiving a latrine go through training for maintenance and hygienic use
of latrines. This should be a non-negotiable condition to receiving a latrine.
For instance, people should know to cover their latrine holes to avoid flies,
which can propagate many serious illnesses
·
Hire manual
labor and amass necessary material. Lists are always good. Disperse material
carefully
·
Plan during
rainy season, build during hot season. If you try building latrines—or many
water source infrastructures for that reason--during rainy season, you run the
risk of having the hole you’re digging collapse
Bottom line: WASH
infrastructure will probably take up plenty of my time over the next 2 years.
There’s a lot to be done…

Technical Training: framework, RME tools, and Malaria
![]() |
| Here we go |
1) Community health project framework
The tech team provided us with a review of the
project framework we were introduced to during PST1. This framework is intended
on helping us fulfill Peace Corps’ 3 main health sector goals by providing
concrete numerical objectives paired with carefully defined indicators. We are
told to “start with the end in mind” when planning projects; that is, we must
always design projects that will directly fulfill the objectives and overall
goals.
The three main goals of community health:
Goal 1-Communities will improve their ability to
prevent and treat malaria
Goal 2-Communities will adopt behaviors and practices
that contribute to overall maternal and infant health
Goal 3-Community members will adopt water and
sanitation hygiene practices and behaviors resulting in improved health
An
example of an objective for the 1st goal:
-By
the end of 2018, 97, 840 community members will increase their access to
malaria prevention goods and services and will adopt appropriate malaria
prevention and treatment seeking behaviors.
Each
objective is
·
accompanied by a
list of projects that will enable volunteers to collectively move towards
fulfilling that objective. For example: trainings, workshops, and distribution
of insecticide-treated bed nets…
·
accompanied by a
number of output indicators, which enable volunteers to measure the scope of
their impact. For example, a volunteer might record the number of
insecticide-treated bed nets purchased by or delivered to her community.
·
accompanied by a
number of outcome indicators; the data yielded will bring PCVs that much closer
to reaching the objective. For example, a volunteer might record the number of
people who slept under an insecticide-treated bed nets last night.
I think the project framework is exciting for several
reasons.
1) The indicators used are standard indicators, which
means that NGOs and governments the world over are using the same indicators to
measure progress. They give Peace Corps and its work credibility as an
international actor in improving community health.
2) The framework—its goals, objectives, and
indicators—hold Peace Corps Senegal and its volunteers accountable for the work
they do. We want to know whether we are effective, whether we are actually
making a SMART (Specific, Measurable, Attainable, Reachable, and Time-bound)
difference.
3) It can serve as a guide and tool for volunteers
designing new projects.
Projects are designed as follows:
Inputs-->Activities-->Outputs-->Outcomes-->Impacts
Concrete example: by teaching mothers how to cook nutritious meals for their children, we will be working towards achieving objective 2.2: “By the end of 2018, 1440 women will adopt at least one infant and young child feeding practices resulting in improved nutritional status”.
| A well-fed pair in village |
Say we want to teach mothers how to make cereamine, a
nutritionally dense porridge, for their infants and young children.
·
Inputs include
time, people, materials
ex: counterpart, chairs, mats, ingredients for
nutritious meal cooking demonstration, mothers and their infants
·
Activities
ex: training on how to make cereamine, a nutritionally
dense porridge
·
Outputs
ex: number of women receiving the training on how to make the porridge
·
Outcomes
ex: number of women who can demonstrate the ability to make the porridge
It’s good to note the difference between outputs and outcomes; just because 20 women attended the training, doesn’t
necessarily mean that they will be making the porridge on a regular basis. I,
for one, used to conflate the two.
2) Recording, Monitoring, and Evaluation Tools
We had a couple of great session on the importance of
taking thorough surveys before initiating any project in order to assess
community need, strengths, and weaknesses. For instance, you don’t want to put
a great amount of time and resources into teaching your village women how to
make cereamine if there’s no malnutrition in your area.
Designing and conducting a survey:
·
Think about your
objectives
-what kind of
information do you want to gather
-remember data must
be relevant to the project framework
-quantitative or
qualitative data?
-practice/behavior is
best assessed through observation and qualitative data collection
·
Choose your
demographic characteristic
-employment status,
gender, ethnic/language group, age, sex…?
·
Plan, plan, plan
-how (interviews,
observation)?
-who (sample type, work
partners)?
Set a deadline and a schedule!
·
Write out your
survey questions and translate your survey questions
-get help from a
language instructor as needed
-test out your
questions on someone first, to make sure they are culturally appropriate and to
make sure they make sense
·
Record your data
-medium (excel
sheet, pre-drawn sheets)?
·
Control for
quality
-are participants’ answers
influenced by [your counterpart’s presence, for example]?
-do your
participants understand the questions?
-is the order of
the questions influencing answers?
-will people be
more responsive to indirect questions?
-observe and use
your judgment
·
Construct an
action plan based on answers
-what does my
community know/not know?
-where can I make an
impact?
Once I get back to village, I’d like to start designing
and conducting a series of surveys. I’m not sure where to start, though.
Malaria or WASH?
3) Malaria
Fun facts:
-Severe malaria can sometimes cause an infected
person’s eyes to turn yellow.
-Many people get malaria at the end of the rainy
season—in November or October—because they stop sleeping under their nets: “no
more rains, no more mosquitoes”. Wrong.
-People who don’t sleep under their nets every night
have many reasons for not doing so. One of those reasons: “nets don’t fit the
room well, or the shape isn’t good” (according to a survey by Networks).
-Pregnant women are more vulnerable to Malaria, due
to changes in their immune system. Apparently, the placenta is also a prime
hiding spot for parasites, since it’s so rich in nutrients and oxygen. This is
all bad new for both the woman and her fetus.
We had a particularly
interesting session with a 5th (!) year volunteer in the south, who
has been working on applied malaria projects. He is deeply involved in bridging
the gap between Senegalese health services and his sick community members. The
bottom line: the burden of illness is unequal in Senegal; opportunities for
seeking out and acquiring health services are not equal either.
“Invisible cases” often slip
through the system. Sometimes, people are too far away from their nearest
health structure, and don’t seek out treatment at all. They may get better on
their own, or not. Sometimes, their lack of confidence in the health system
discourages them from going: they doubt that the medication will be available,
or they have poor rapport with health care providers. In my own experience, I notice
that my ICP tends to take on a very patronizing and dismissive attitude when
interacting with his patients.
“Lost cases” are also
frequent. These are patients with malaria who do make it to a health structure,
but whose diagnosis cannot be confirmed. Senegal is often subject to medical
stock-outs or breaks. Sometimes, RDT (Rapid Diagnosis Tests) are unavailable.
Instead, they are diagnosed with diarrhea or respiratory illnesses, which have
overlapping symptoms with malaria.
So: can we actually know the
frequency and burden of malaria?
As this gap between
resources and people narrows, the recorded incidence of malaria may very well
increase. This is tricky: it does not necessarily mean we’re not making progress
in preventing new malaria cases; in fact, the actual prevalence of malaria
cases may very well stay the same or even decrease.
Numbers are always stickier
than we think.
More to come...
