Baseline Gender Analysis

Tomorrow the Baseline Participatory Gender Analysis of Fish on Farms will begin. The purpose of this is to gain a better understanding of the role gender plays in mixed-farm livelihood systems. This process involves a number of Participatory Rural Appraisal (PRA) tools to collect the data. A participatory process is particularly important as it involves the community participants, who will be the agents of change,  to be engaged as co-investigators. The information gained here will be used to inform a “Gender Aware” behaviour change for the project.

More specifically the tools we will be looking at are:

1) Historical timeline of gender changes – to understand how gender roles have changed in recent years, what factors have made them change, and what community members think about these changes.

2) Bodymap (image of ideal husband/wife) – to illustrate behavioral expectations and images for men/women, and to identify the consequences for people who do not follow it.

3) Market and extension access – to understand different agriculture and aquaculture institutions and services in the community to which men and women have access.

4) Gender division of labour – to view how household management tasks are divided among household members, to understand men’s and women’s views about what constitutes “work’’ and to demonstrate a tool that will help community members assess their situation.

5) Fish preference ranking – to better understand categories and species of fish that men and women prefer for consumption and marketing. And to identify any food taboos associated with different fish species and to explore decisions to sell or to consume fish products.

6) Asset control and management – to understand how men, women, and elders have ownership and decision-making control over critical livelihood assets, and to understand how men and women define “control” over asset-related decisions.

7) Seasonal calendar matrix – to understand seasonal and gender patterns related to the production, sale and consumption of agriculture and horticulture products, and how decisions about sales and consumption are made.

8) Financial management and meanings of income controlto understand the diversity of sources of income from men, women, and other family members, and how different family members are involved in managing, saving, and making decisions about income.

9) Nutrition and coping strategies – to understand the relationship between food and health/well-being; how people try to maintain good health for the family; and how they cope when food supplies are low.

10) Key informant interview – to better understand community leadership opinions on gender issues, opportunities, and priorities in the community.

The implementing staff, comprising of the HKI and NGO field staff officers, were trained over the past week to administer the research exercises. The training was focused on conveying the concept and purpose behind each tool and questionnaire guide. Each tool was reviewed and practiced separately, through team work and participatory learning.

Since the quality of the research is dependent on the responses given, special emphasis was put on asking “probing questions”.  This style of questioning is of particular importance, since oftentimes there is a lot that we can learn by simply questioning the responses given, such as “why is that important?” Or “What happened as a result?”

With these skills at hand, the implementing staff are now equipped to facilitate an open dialogue to gain insight into the role gender plays in these communities. Over the next seven days the research will be paced to allow for a full day of data analysis in between each data collection day. This method allows for critical reflection of the findings and minimizes loss of detail.

Stay tuned for more on the Baseline Gender Analysis from our new students in the field (and authors of this post), Pardis Lakzadeh and Hellene Sarin!

Pond Construction

Pond construction has begun!

After many weeks spent in conference rooms and on field visits with the Fish on Farms aquaculture experts, the innovative fishpond design has been finalized and the first fishponds have been dug.

At the heart of the Fish on Farms project, is the novel approach to increase micronutrient intake by increasing household access to large and small fish species. Fish is one of the most commonly consumed animal source foods in Cambodia so the ability to increase access to fish and fish products should have a direct impact on family nutrition.

Currently, fishpond construction is underway throughout the four “Operational Districts” encompassing the FoF study area. Due to the difficult terrain, approximately 20% of the ponds are being dug by hand. Four excavation teams – locally hired construction companies with access to the necessary machinery – will dig the remaining 260 ponds over the coming weeks. Specially trained aquaculture experts from Helen Keller International and the local NGO are supervising the construction.

The design of the fishpond is key to the success of the project: the walls of the pond are sloped to ensure structural stability while maximizing the surface area of the water; the ponds are to be dug at least 10 meters from the household water source in order to prevent contamination of drinking water; and the site for the ponds must not be obstructed by large trees, so that the pond is exposed to sunlight and can maintain the correct nutrient balance.

It has been a particularly dry monsoon season in Prey Veng this year, which has allowed us to begin construction so late in the season. We’re hoping for a few more dry weeks until all 330 ponds are dug, followed by a few months of heavy rain to fill the ponds with water.

The aquaculture team is now working to determine the best ways to stock the ponds, and is sourcing fish fry and fingerlings. Striking a balance between the small nutrient-dense fish, which are most commonly eaten in poor, rural areas like those in Prey Veng province, and the large, valuable fish that can be sold in the market is an important consideration. More on that soon!

Blood Analysis: Part 1

 As promised, I wrote about the “5Ws” of our blood collection: who, what, when, where, and why. I even threw in the “how”. Today’s post focuses on what happened in the field.

One of the most important (and expensive!) components of FoF is the blood collection and subsequent analysis. This process provides us with concrete evidence that there are more (or less) nutrients in a person’s body by looking at biochemical indicators of nutritional status. Obtaining this information is what sets FoF apart from previous homestead food production interventions.

During baseline blood was collected from 450 women. We will collect samples from the same 450 women during endline for a paired analysis. While we considered collecting blood from children as well, it was decided this would be too traumatic. Plus, we had other less-invasive methods available to assess whether or not children were anemic (finger-pricking to measure hemoglobin).

When we arrived in each village, a random lottery was held. Each house was assigned a number (1-10) and slips of paper with those numbers were randomly selected. In the end, we selected 5 women from each village. Women were given an ID number and asked to report to their local Health Center the day after our visit to their village.

The morning of collection, the local Village Health Volunteer (VHV) came with the women and their children to the Health Center. The VHV was responsible for making sure everyone who agreed to provide samples was present. Most mornings everyone was at the Health Center by 7:30 am, as they had to fast for a minimum of 3 hours before providing samples. When all the women assembled, they were briefed by Mr. Tee from HKI.

One at a time, the women entered a room where a technician was working. The technician drew 3 vials of blood. After, the women were given a sarong as a thank you for their participation.

Two of the vials collected were 4.5 mL test tubes containing Ethylenediaminetetraacetic acid(EDTA), which is an anticoagulant, that prevents blood from clotting. They were then packed on ice and transported via a car we dubbed the “Blood Taxi” to the National Institute of Public Health Laboratories (NIPHL) in Phnom Penh for further processing.

The third tube collected was a 7 mL trace element free tube. It was centrifuged in the field. This separated the blood into 3 components: the serum plasma, the buffy coat (most of the white blood cells and platelets), and the erythrocytes (red blood cells). The serum was packed on ice and sent to the NIPHL, where samples were stored at -70 degrees Celcius until the end of baseline.

Check back tomorrow to find out what happened once the blood arrived at the NIPHL.

Baseline: Day 14 (VMF)

This afternoon our anthropometry and hemoglobin analysis stations were set up at the home of a Village Model Farm (VMF). I was really excited because I hadn’t seen a VMF yet, AND because our VMF concept just received press as of yesterday! (Click here to read an article about FoF in the New Agriculturalist) I had the chance to speak with the VMF representative in the village of Svay Trai, and thought I would share what I learned on the blog.

The backstory: Sophal Eab used to be a wedding stylist, but when her children were old enough to attend school, she needed a job that required less travel. When the opportunity to have the VMF in her village arose, she took it. Until her farm is up and running, she sells corn for income. She purchases 500 ears of corn for $40 USD from her local market (160,000 Riel at 320 Riel/ear). She then boils all of the corn and sells it from a stand in front of her house for 500 Riel per ear (sometimes she has to sell it for less if it’s not good quality corn). Taking the cost of fuel into account, she makes roughly 100 Riel per ear, leaving her with a profit margin of anywhere from  50,000 Riel ($12.5 USD) per day to 100,000 Riel ($25 USD) per day depending on the quality of the corn available at the market.

A happy customer!

Making the most of leftovers.

Sophal has already impressed FoF with her dedication. Within one month she has raised the height of the land on her property to better support the beds needed to grow fruit and vegetables. She purchased wire and sourced local bamboo to make a fence to keep animals off of her farm. She also bought mango seeds so she could start growing mangoes. Luckily, she already had a fishpond, but she is considering expanding it. FoF will provide her with other seeds for her farm and fingerlings (small fish) for her pond. For now, all she knows is that she has to grow a variety of fruit and vegetables and follow the guidelines given to her by HKI and FoF, but she is looking forward to her training. She hopes to grow enough of her own corn so that she can increase the profit margin of her corn stand by not having to purchase corn from the market.

The new fence is working out quite well!

The VMF will play a very important role in FoF. Each village will have a VMF, and the VMFs in the aquaculture villages will also have a fishpond. The VMF representative will be a woman who receives training and inputs as part of our intervention. She will learn about homestead food production (HFP), aquaculture, and sustainable agricultural practices. There will be a marketing component to her training that will include information on how to plan the planting and harvesting of crops according to the seasons (of which there are 2 here – wet and dry), how to price crops, how to pick a good market to sell her produce, and how to form a marketing group to share information with VMF representatives from other villages. For instance, the marketing group may discourage women from growing morning glory (a common leafy green vegetable here) because it can be grown anywhere and with little input, so it doesn’t fetch a good price at the market. There will also be gender-specific training, as one of our goals is to empower women by improving both their health and their opportunities for income. The VMF representative will teach the FoF households in her village how to use their new farms and fishponds. Her knowledge will be e a local resource for other households in the village. She will be monitored every 4 months by FoF to see how her farm, her fishpond, and her “students” (the other FoF households in her village) are doing.

There is also a nutrition education component of our project that is being carried out by Village Health Volunteers (VHVs). The details, however, are another story for another day.

Sampling Methodology

One of the issues that we have encountered during the first week of baseline is that some of the houses that were originally selected to be part of the study are no longer eligible.

In some instances, the mother went to Phnom Penh or the Thai border to seek work. The purpose of our study is to show the effects of HFP and aquaculture on household food security and the nutritional status of women and children. As such, the woman of the house must be present year-round to reap the benefits of these interventions. By migrating for work, a woman’s nutritional status at the end of the study would not reflect the addition of HFP and aquaculture in her life. Therefore, her household is now ineligible for participation in FoF.

In other instances, when we arrived at the house we found out that the children were over the cutoff age of 5 years old. This happened for a variety of reasons: some women couldn’t accurately remember the date of birth (the Khmer calendar is different from ours), the selection team didn’t check the proper documents to verify the child’s age, or the age on the village chief’s list was incorrect. It’s also possible that some women provided false ages for their children because they wanted to be part of a study that provides the expensive inputs needed for HFP and aquaculture.

In any event, our team has been scrambling to fill their spots so that we have the right sample size for the study. We’ve accounted for a possible 15% of houses lost due to follow up, but we want to start with the biggest sample possible to minimize that loss given how expensive and time-consuming the project is. 

This seems like a good opportunity to discuss the methodology behind household selection. In an earlier post (Household Selection), I briefly outlined the criteria that households needed to meet to be part of FoF. However, meeting the selection criteria does not mean a household is automatically enrolled in FoF. This is, after all, a scientific experiment; certain research principles must be upheld.

In order for this to be a valid and reliable scientific experiment, we need our sample to represent our target population as closely as possible while eliminating any potential biases or confounders. We achieve this by picking the proper sampling method. FoF is using a multi-stage sampling strategy. The first stage is cluster sampling, which is a form of probability sampling that examines naturally occurring groups such as villages. The second stage is systematic sampling, which is used to select the houses in the villages by picking a random point to start (eg the fourth house on the list) and continuing through the list in a systematic fashion (eg every fourth house on the list). A few key definitions are needed at this point:

  • Valid – we are measuring what we say we are going to measure
  • Reliable – our measurements are as accurate as possible
  • Probability sampling – the entire target population is known, and thus everyone in that population has an equal chance of being selected
  • Randomization – picking units (in our case, villages) at random to ensure the sample is representative of the target population
  • Target Population – the population we want to study, as defined by certain parameters (eg location, age, SES)

First, we looked at all of the villages in the province of Prey Veng on a list from the most recent census conducted by the Ministry of Planning in 2008. We excluded the villages that had already been part of a HFP program by HKI that was funded by the EU, the villages that are part of the ongoing ODOV (Organization for Development of Our Villages – one of our partner NGOs) food security project, and the villages that are taking part in other Cambodian NGO projects. This left us with 164 villages in 4 districts: Ba Phnum, Kamchay Mear, Me Sung, and Svay Antor. Then the villages were randomized, resulting in 120 villages with 40 villages per group (HFP, HFP + aquaculture, or comparison) being selected.  Finally, 30 out of 40 villages were selected after further randomization.

Workers from the ODOV went into the field and met with the village chiefs (and in some instances, a village council) to divide the households with children under the age of five into 3 categories: poorest, poor, and medium wealth. They wrote their wealth ranking assessment for each household on a slip of paper that was placed into a box to maintain anonymity. This was done because it was our intention to try to help those most in need.

The ODOV and the village chiefs met with the households categorized as poorest or poor to explain the project to them and to ask if they were interested in joining. If they responded “yes”, field staff went to the house to make sure it met the selection criteria. They made sure that each house had enough land to support HFP farms and fish ponds, and they assessed whether or not the house would be able to maintain these projects during the course of our study. They also inquired about the ages of the children, most often by looking at the village chief’s list of villagers, but as we’ve discovered this list isn’t always correct.

A list of all eligible households was sent back to HKI. The houses categorized as poor or poorest were listed, and from that list we began with the 4th house and picked every 4th house after that. We were able to find 10 eligible houses in each village by using this method. The ODOV received a list of selected households and went to the village chief to inform him of the date and time of the survey.

In the field, each supervisor brings his or her list of 10 households per village that have been selected for the study. Sometimes, something goes amiss and the household is no longer eligible (for all of the reasons I listed above). Then we have 2 options: 1, we pick another house categorized as poor on the ODOV list that wasn’t originally selected during the systematic sampling; or 2, we go back to the very first list that the ODOV produced (the one that listed all the households in the village before the wealth ranking) and we discuss with the chief whether or not picking a new house from that list is a good idea. This means that sometimes we will get houses that vary in socioeconomic status (SES). Ideally, we’d like to control for SES before we collect data, but our survey includes a module about household income and wealth that will allow us to control for SES after the data has been collected.

Once we have our 10 houses picked in the village, we hold a lottery to randomly select 5 houses to participate in the 24-hour recall and blood analysis components of our study. Slips of paper with the numbers 1 through 10 are placed faced down, and 5 slips are drawn. Those houses are highlighted on the list. If, for some reason, we have to replace a house that has been highlighted, the replacement house is automatically assigned to be part of the 24-hour recall and blood draw. The enumerator goes to the house to conduct the 24-hour recall and to obtain consent (very important) for the blood draw. The woman is given a slip of paper that has her unique identifier and the time and location of the blood draw. We are only conducting recalls and collecting samples from 450 women (half of the women in the study) because the recalls are time-consuming and the blood collection is invasive and expensive.

Households selected by lottery for the 24-hour recall and blood draw

And that is the method we used to recruit 900 households for FoF while adhering to the principles of sound research as best as we possibly can.

I’d like to give a special thank you to Sokhoing Ly from HKI for explaining all of this to me with great patience.

Test Survey

Preparations are underway as the countdown to the baseline survey continues. Yesterday morning we checked off one of the most important “to-do”s on our pre-baseline checklist: the test survey. After a week of training, our enumerators had the opportunity to put their new skills to use. This also gave us a chance to work out any “bugs” in the survey.

The day began bright and early, as two vans carrying 20+ people departed from HKI’s office in Phnom Penh to head to the province of Kampong Chhnang. Although FoF is taking place in the province of Prey Veng, Kampong Chhnang is closer to Phnom Penh, and was thus better suited for a day trip.

Our first stop was at the Longvek Health Center, where we picked up iron and folic acid tablets to distribute to the households we were going to visit.

Outside the Longvek Health Center, our first stop in Kampong Chhnang.

Our next stop was at the home of the village chief. We informed him of our plans to meet with different households and ask them questions about nutrition and health. He directed us to the house of the village health volunteer, who would be able to assist us in identifying suitable households to visit.

The final stop for our van was at the house of the village health volunteer. The second van went to the next village to find more households to survey. Outside of the volunteer’s house, the enumerators set up stations to conduct anthropometric measurements and blood analyses. Then the volunteer took us to different houses to meet with women and their families. As an incentive, every woman who agreed to speak with us received a bag of detergent.

Bags of the detergent we distributed as an incentive to participate in the test survey.

The first house we visited was the home of a husband and wife whose three daughters were present. Two of the daughters lived in adjacent houses, while one still lived at home. We interviewed the two daughters who had young children.

As the enumerator worked his way through the survey, I had time to observe the family’s home. Houses in Kampong Chhnang are very different from houses in Vancouver! The houses are all raised so that the “house” part is actually the second story. Underneath the house is the area where most family activity occurs. There are cots, tables, and chairs underneath, taking advantage of the shade the raised portion of the house provides. The cooking is done in a separate area nearby on the property. The kitchen I observed consisted of a cupboard and a heat source. Most families eat from the same pot. This particular family also raised chickens who roamed the yard freely.

The question portion of the test survey went fairly smoothly. One of the challenges was that the infant wanted breast milk before his nap. However, women aren’t comfortable breastfeeding in front of strange men. Unfortunately, it was hard to find enough female enumerators who are able to leave their homes for the 2+ weeks of baseline, so the majority of our enumerators are men.

The final portion of the test survey involved bringing the women and their children to the village health volunteer’s house to get measurements and blood. First the women were weighed, their height was measured, and their mid-upper arm circumference (MUAC) was recorded.

Then their children went through the same process. Most of the small children cried when they were placed on the length board! It must have looked like a scary contraption to them.

Finally, the women and children had their fingers pricked. A drop of blood was placed on a slide that was fed to a machine to analyze the hemoglobin content of the sample. Based on the results, many women were given iron and folic acid tablets.

The day concluded back at the HKI office in Phnom Penh. Everyone gathered to discuss their experiences and raise any questions or concerns. A few questions were further clarified on the survey, but overall the results of the test survey were encouraging. Our enumerators are now confident and prepared to head to Prey Veng for baseline next Wednesday!

Getting Started

Welcome to the Fish on Farms blog! This blog will be chronicling the very exciting Fish on Farms (FoF) project, which is being jointly conducted by the University of British Columbia (UBC) and Helen Keller International (HKI) in the Prey Veng province of Cambodia.

First, a brief introduction to your blogger over the next few months. My name is Carly Isman, and I am a 4th year student in the Faculty of Land and Food Systems at UBC, studying  Food, Nutrition, and Health. I’m in Cambodia from June through August to cover everything FoF-related, from press coverage to our baseline survey, which is coming up very soon! For those of you with shorter attention spans, I will also be tweeting.

In the short week that I’ve been here, a lot has happened. Most importantly, I met Dr. Christopher Charles and Ms. Kyly Whitfield, two people from UBC who will be here in Cambodia to work on the project and who have already been hard at work to get FoF organized. I attended my first Nutrition Working Group meeting, where I got to hear about several projects relating to nutrition that are currently underway in the country. I’ve been to HKI’s offices twice to meet the people who are working on FoF and to hammer out the details for the baseline survey. On top of all of that, I’ve been exploring Phnom Penh and learning about the city’s charming idiosyncrasies.

FoF has been in the press twice in the past week, which we’re very excited about! The International Development Research Center announced our project in a press release, while The Vancouver Sun wrote an article about our project. I’ll be discussing these in more detail later, but right now it’s dinner time (both for me, and for the mosquitoes who will inevitably eat me while I’m eating).
