World Water Day: Let’s Unite for Clean Water

Written in collaboration by Brooke Edwards and Maegan Clark

In 1992, the UN designated March 22 of each year as World Water Day. Although Heifer International’s focus is on ending hunger and poverty, clean water (for people and livestock) is absolutely essential for our project families and communities to thrive. In observance of this year’s World Water Day, we thought we would shine a light on how water plays an important part of our work all over the world and give you a few ways you can help bring safe drinking water to the world’s poor.

In many of our project communities, the lack of access to clean potable water is one of the most critical challenges. Many communities depend on unsafe water from unprotected shallow wells or rivers. Lack of access to water is a threat to the livelihood of a community in many ways. Inadequate access to water negatively affects the productivity of livestock and crops, and unsafe drinking water is a health hazard to both communities and animals. It is primarily the responsibility of women and girls to fetch water for household and animal use, often walking long distances in harsh conditions. Water scarcity is believed, for this reason, to affect the enrollment rates as well as educational performance of girls.

In this video you’ll see Fatou Dione walking in oven-hot wind churning with dust to fetch water for her husband and four children. It’s the dry season in her village of Diarrere in Senegal, and both water and food are running low. At the time this video was shot, they were eagerly anticipating the rains the following month.


To address water scarcity in our project communities when needed, Heifer partners with organizations specializing in water projects to bring deep-water wells and pumps to the area. Consistent with our methodology of helping families and communities become more self-reliant, local people are trained to maintain the wells with locally available resources. And to ensure the sustainability of the boreholes, water management committees are established and trained.
Improved sanitation is also crucial for our projects. In Uganda, Heifer participants are using a clever hand-washing station called a Tippy Tap. It allows you to wash your hands without touching anything in the process.

These really make sense when running water isn’t available. Much better than a bucket, that’s for certain. We all know hand washing is a key way to stop the spread of many diseases. In a country like Uganda, which has a life expectancy of 52.98 years (yes, in large part a result of HIV/AIDS), avoiding disease like bacterial diarrhea is of the utmost importance.



The Tippy Tap is a cheap device made of locally available materials. It was initiated by Heifer Uganda at this farm and others as one way of ensuring that family members and their visitors wash their hands with soap each time they use the pit latrine. In so doing, the possibility of spreading disease is minimized.


So what can you do to help?

  1. Help fund our Building a Sustainable Way of Life Project in Peru, which will improve community wells to ensure the availability and quality of water in wet years and dry.
  2. Team up with US-based groups who are calling for increased commitments by the US government to help increase access to safe drinking water and improved sanitation for millions around the world.
  3. Find and attend an event near you.
  4. Visit a local restaurant participating this week in UNICEF’s Tap Project, and pay a $1 (or more!) donation for otherwise free tap water.

Biogas is Important for Rural Children

Posted on by

From my trip to Uganda, I was able to see firsthand why biogas is so important in poor rural communities. So far, I’ve shown you why it’s important for women and for the environment. Now, I’d like to show you why it’s important for rural children.

The very first farm we visited was that of Miriam and Wilberforce Muwonge in the Ntaawo Ward, Mukono District. Miriam and Wilberforce live with their three children and six grandchildren on about one acre of land. The family had already participated in a Heifer project, from which they received one dairy cow. They had little money for fuel for cooking and lighting, but they had plenty of cow manure. Since Heifer Uganda installed their biogas unit, they have been saving the equivalent of U.S. $10 a month on fuel costs. The children are not only able to attend school, but they are also able to study at night in their home.
In contrast, while driving to another field visit the next day, we passed three boys carrying loads of firewood on their heads. These were not the children or grandchildren of Heifer participants. They most likely do not get to attend school, because they are busy gathering firewood and probably water.
As a mother, I was understandably drawn to the children I saw on this trip. To see the difference Heifer makes in the lives of children was amazing. They look healthy, their clothes are cleaner, they go to school, they read books. The gifts of a dairy cow and a biogas unit, and the accompanying training, sure go a long way.

Appropriate Technology Keeps Your Hands Clean

I know I seem to keep harping on about biogas (and there’s more to come!), but that’s not the only form of appropriate technology we saw in Uganda. Here’s a clever hand-washing station on a farm we visited. It’s called a Tippy Tap, and it allows you to wash your hands without touching anything in the process.

We saw a couple of these on our trip, and they really make sense when running water isn’t available. Much better than a bucket, that’s for certain. We all know hand washing is a key way to stop the spread of many diseases. In a country like Uganda, which has a life expectancy of 52.98 years (yes, in large part a result of HIV/AIDS), avoiding disease like bacterial diarrhea is of the utmost importance.
Under Heifer Uganda’s holistic farmer training curriculum, families participate in a course on home hygiene. Farmers are trained to keep their homesteads clean and tidy and to ensure reasonable hygiene and sanitation. This practice goes on in many of Heifer’s projects worldwide.
The Tippy Tap is a local, cheap device that is affordable by all families. It was initiated by Heifer Uganda at this farm and others as one way of ensuring that family members and their visitors wash their hands with soap each time they use the pit latrine. In so doing, the possibility of spreading disease is minimized. The training and demonstration on how to make and use the Tippy Tap is done at one participant farmer’s home, and thereafter each participant goes back home and makes one for the family.
The water used is clean and safe, drawn from individual roof water tanks–simple water harvesting techniques introduced to families by Heifer Uganda. When available, community protected wells, communal boreholes, natural springs and sometimes piped water may be the family’s water source. The water sources, in most cases, are within walkable distances, and families ensure that the container has water in it at all times.

Biogas is Important for Rural Women

How many times have you prepared a meal today? On a typical day at home, I’d say I use my stove or microwave three or four times. I cook eggs for breakfast, microwave oatmeal. Steam veggies for my daughter a couple of times, and cook dinner for my husband and myself. Until my trip to Africa, I hadn’t thought much about the convenience of being able to fix a warm meal any time I felt like it.
For the vast majority of families–women, really–in rural Uganda (okay, lots of countries), cooking means something entirely different.

Through the photographer’s lens, this scene has a romantic feel to it. It reminds me of camping. But camping usually only lasts a weekend, not a lifetime.
Cut and collect firewood. Start and maintain the fire. Breathe the smoke and soot. Teach your daughter the same.
Compare this:
With this:
Which would you prefer, day in and day out? Biogas is an affordable, accessible alternative that frees a woman from the tedium that comes with cooking over an open fire. It is better for her health, and for that of her children. Stay tuned to see other reasons biogas is important.

Biogas in Uganda – Any Questions?

Hujambo from Uganda!


This afternoon, Dero and I got to visit the Heifer Uganda office. I had the chance to meet a handful of my colleagues and to see where they do their work. A particular treat was meeting Beinempaka Athanasius, who is the program coordinator for the Uganda Domestic Biogas Program. At the bottom of this post is the profile for this project, to give you a little context.

The other five countries under the larger umbrella project are Burkina Fasso, Ethiopia, Kenya, Senegal and Tanzania. In Uganda, a project participant must pay at least 70 percent of the cost of installation. That 70 percent can come from their own savings or through a microcredit loan from a grassroots cooperative. The remaining 30 percent comes from external funding. Currently, there are three different sizes of units available to participants: 6 cubic meters, 9 cubic meters or 12 cubic meters. There is talk of adding a model in 4 cubic meters. The cost of the smallest unit (6 meters) is approximately U.S. $700. To Dero and me, that sounded like nothing. But to Heifer Uganda staff, as well as the participants, that’s a mighty hefty sum.

A challenge that this project has faced is cultural acceptance of the biogas units. To combat this, Heifer Uganda has worked to sensitize communities to how the units can help them. They even have a mobile unit they take with them to make demonstrations. It is often easier to get a family to buy into the concept of using their livestock’s waste to make fuel for cooking and lighting; human waste (which produces a great deal of methane and acts as a catalyst to speed up the breakdown of livestock manure) is another story. Each time a biogas unit is installed, however, a pipe is connected to the composting toilet, but the valve is not turned on until the family agrees to it.

Heifer Uganda staff showed us a handful of biogas stovetops and lamps. Until recently, the project imported the stovetops from China. They soon realized, though, that they could teach people to make them locally and less expensively. Surprisingly, the lamps imported from China cost less and are more efficient than anything that can be made here in Uganda. There is such a high demand in Kenya for the lamps, in fact, that you can find them in markets across the country.

The bottom stovetop is the import from China.
The one on top was designed and made in Uganda.


This is the Lotus2. It is the newest biogas stovetop being made in Uganda.

Although biogas has been catching on in Uganda and the other countries participating in the project, it appears that because of the struggle to market the units, as well as the time it takes to train the technicians, promoters and service providers, Heifer Uganda will fall short of installing the target number of biogas units. With such an exciting and promising appropriate technology, it is easy to see how ambitious a project might become, planning to install too many in too short a time.

But there’s absolutely no doubt that these units are changing people’s lives. I look forward to visiting, and sharing with you, families who already have biogas units installed and in use.

What do you think? What would it take to convince you that biogas is the way to go? What questions do you have about biogas?

Uganda Domestic Biogas Program
The growing demand for fuel has resulted in pressure being exerted on the environment. Trees are cut to provide wood and charcoal for cooking, and burning of fossil fuels has had damaging effects on the environment. Smoke from burning of fuel wood is a hazard to human health. In addition, the cost of domestic fuel is much higher than most households in Uganda can afford. Biogas provides a cheap alternative source of energy for cooking and lighting. The Uganda Domestic Biogas Program therefore aims at addressing this gap by developing and disseminating domestic biogas in rural and semi-urban areas offering the Ugandan population the benefits derived from the use of clean biogas for cooking and lighting and using the bio-slurry to increase agricultural yields with the ultimate goal to establish a sustainable and commercial biogas sector in Uganda.
The program will target 12,160 biogas households in the five-year project cycle. Biogas technology as local knowledge has not been institutionally operational in many parts of Uganda, and the introduction will be a considerate and phased approach. During the first six months, at least 120 biogas plants will be constructed – 90 demonstration and 30 regular plants. The program will start in more densely populated areas, particularly where dairy activities are common (e.g., where Heifer Uganda, Send A Cow and other NGOs have placed cows). Outreach will be improved by making use of partnerships particularly with NGOs, local councils and religious communities active in remote areas.
A multi-stakeholders sector development approach will be used and is based on the establishment, over time, of a market for domestic biogas installations and accessories, in which a well-informed demand side (i.e., in which clients who know what they want and recognize quality and value for money links up with an equally capable supply side that provides the market with quality products at competitive prices and with adequate after-sales services). Such a market is expected to reach a volume that allows a significant number of constructors and credit providers to maintain an economically-sound and profitable level of turnover. In the process toward market development, the government, civil society organizations, and other players in the public and private domain have a role to play, in addition to the main actors in the market.
Particular attention will be paid to vocational training and business development. In Uganda, there are few contractors and skilled masons. No hard data is available on the presence of appropriate construction companies willing and able to build, maintain and repair bio-digesters. Most of the registered construction companies are located in the urban centers. In the past, numerous artisans have been trained in all kinds of masonry and have now established their own micro-enterprises, often not registered as a company. These artisans have the basic knowledge to qualify for the bio-digester mason training and are ideally situated in the villages. If there are not enough registered construction companies available to satisfy the demand, self-employed artisans will be approached to form bio-digester construction teams. The perspective is that these teams will transform into small but full-fledged companies in the long run.

A Small Farm Perspective on the UN Climate Change Summit

This year’s international round of discussion on climate change is taking place in Cancun, Mexico. Officially known as the United Nations Framework Convention on Climate Change, this summit is focusing on numerous topics – not the least of which is greenhouse gasses. Indeed, one of the important themes around climate change has to do with mitigation of the effects of greenhouse gasses – in other words, “What can we do to make these changes less severe or hostile?”

Here at Heifer, we’ve been answering this question for years through our innovative yet simple agroecology programs. All over the developing world we’re fighting the environmental effects of greenhouse gasses by training smallholder farmers to use sustainable methods of rearing animals and raising crops.

Here are just a few of our programs that improve local ecosystems while helping families lift themselves out of poverty:

· Improving soil water retention through planting trees and wise grazing management

· Controlling soil erosion

· Rotational grazing practices for small and large ruminants like goats, cattle, llamas alpacas, and water buffalo

· Periodic or sustained use of zero-grazing pens

· Improved animal feeding with local resources, using an educated understanding of animal nutrient requirements

· Better manure management through composting, covering wet and dry manure storage and incorporation of this animal by-product in crop grounds.

While animals and animal by-products do emit greenhouse gasses, an educated understanding of where these gasses come from and means to reduce their impact are mitigation practices that can be accomplished by all smallholder farmers.

Let me offer a real-world example: In the Conco community in Copan Ruinas, Honduras, the family of Jesus Esquivel and other partners of the local Heifer Honduras project have transformed the fragile surrounding hillsides from erosion and excessive tree harvesting to a sloping landscape that now holds water for irrigation, productive livestock for community markets and a school for local children. This has been accomplished through wise management of livestock grazing and zero-grazing pens, tree planting, contour land management for farming, manure composting and application to soils, along with improved kitchens using biogas from the animal pens and improved stoves.

The issues surrounding greenhouse gasses and climate change are many and complex. Heifer International can speak with authority on ways to mitigate the effects of climate change as we’ve seen our model yield real, life-changing results in some of the world’s most vulnerable communities.

Cooking Up Something Better

Poverty can be dangerous in all kinds of ways we don’t normally think about. Take cooking dinner, for instance. The job falls to woman in most parts of the world, and that job is often a smoky, choking chore conducted over open flames. It’s estimated that 2 million women die each year from exposure to all that smoke and the toxins that come with it. And smoke from cooking fires contributes to the deadly pneumonia that so often strikes children in developing countries.

On Tuesday, Hillary Clinton announced that a collection of governments, NGOs and private companies is coming together to distribute cookstoves that are better for both the environment and the people using them. The best part of the plan is that there will be no one-size-fits-all stove going out to Ecuador, Indonesia and all points in between. Instead, participants will choose the stove that suits them best.

“If local tastes are not consulted, [the stoves] will stack up and not be used,” Secretary Clinton said at the annual meeting of the Clinton Global Initiative, where she announced the Global Alliance for Clean Cookstoves. Read the Christian Science Monitor article here. The plan is to have 100 million new cookstoves in place by 2020.

Providing improved cookstoves has long been a tenet of many Heifer projects around the world. The stoves cook food more quickly and cleanly, preserving human health and saving trees that might otherwise get chopped for fuel.
