Building fog catchers and artificial waterways in Mexico

In recent years, farmers in the rural town of Santa Maria Yucuhiti in Mexico’s Oaxaca state, have struggled to cope with climate change.

“Santa María Yucuhiti has never been an easy place to live, however, the last seven years have been the hardest I can recall,” Eleuterio said during a Climate Crowd interview. “We have always dealt with frosts and droughts, but now they are harder and more unpredictable; we do not know when to sow in order to avoid losing crops”

--Eleutario, Farmer

To cope with the more frequent and intense frosts, in 2016, community land owners agreed to start sowing in areas bordering communal forests where crops would be less exposed to cold winds and thereby suffer less frost damage. However, the use of “slash and burn” farming in close proximity to forests resulted in two fires that went out of control, damaging about 15 hectares of native forest. To improve crop survival without adversely impacting forests, WWF funded an innovative project in partnership with Espacio de Encuentro de Culturas Orinarias (EECO), a local NGO, to install fog catchers combined with artificial water channels surrounding crops. Fog catchers collect water from the atmosphere during periods of drought and feed into the water channels which, in turn, create a micro-climate that reduces frost-related crop damage and maintains soil moisture. Despite a combination of frost and heat wave events in January 2018, crops in treatment plots experienced a 95% survival rate while the control plot had a 25% survival rate.

Introductory meeting held with local indigenous authorities to present the project and collect baseline information (land use maps, type of soils, agriculture techniques used, types of crops, production and productivity).

Treatment and control plots selected based on suitability of the land, willingness of owners to participate, and suggestions made by municipal authorities. 

Fog catchers and water channel systems designed based on consultations with experts in soil, agriculture and engineering.


Water channels designed to be 0.5 meters in depth and 0.75 meters in width, with 3 meters between each channel as shown in the above figure. Channels are protected by a geomembrane to avoid percolation of water into the highly permeable soils. Due to its dark color, the geomembrane absorbs sunlight during the day, which is then released as heat throughout the night. 

Workshop conducted in June 2017 with selected farmers to introduce the project, provide training on installation of fog catchers, and complete installation

Second workshop conducted in late summer on water channel construction, which was completed over the course of two days

Community sowed 10 treatment plots at the beginning of September 2017

All planting and construction activities completed prior to November 2017, when the first frosts of the season typically occur

Monitoring of crop survival and functioning of water channels and fog catchers


Important considerations

  • An unusual hail storm killed all crops in both the treatment and control plots, after which crops had to be replanted. Any adaptation project should take into account other potential hazards that may occur and take steps to avoid or reduce negative impacts. This project was designed to protect crops against frost and drought events but not hailstorms. Project participants and organizers are currently considering additional measures to take to address hail in the future.
  • Water collection potential of fog-catchers can be reduced significantly with north winds, which cause fog to move rapidly. The community should use alternative water sources to feed the channels on these occasions (ex: installation of rainwater harvest systems as a back-up)
  • Farmers interested in replicating the system should conduct a soil profile analysis of about 1m in depth to identify the right way to build the channels and proper use of materials. The length of the water channels can be adapted to plots characteristics.
  • During the hot season, water channels must be empty to avoid the proliferation of mosquitos.
  • Farmers found that water channels could be used as a water source for wildlife. Some foxes have been seen approaching the site to drink water. However, farmers discovered two had drowned after falling in. To avoid this unintended outcome, farmers placed net ladders within the channels. Since then, there have been no reported animal mortalities.
  • Due to the emergence of cyanobacteria colonies, use of channel water for human consumption or irrigation is not advised unless properly treated.



Direct Outputs 

- Four fog catchers installed 

- Ten waterways constructed 

Capacity Building 

20 volunteers from the local community trained on fog catcher and water channel construction


During January 2018, a combination of frost and heat wave events affected replanted crops. Nonetheless, in treatment plots, 380 plants out of 400 survived after these events (95% survival rate) while only 50 out of 200 survived in the control plots (25% survival rate)

Implementing conservation agriculture in Tanzania to reduce vulnerability of rural farmers to climate change

In the highlands of Karatu District, farmers have experienced declining yields due to frequent drought and soil degradation, which is exacerbated by increasingly erratic rainfall. To improve farm productivity in the face of climate change, the School for Fields studies  in collaboration with the local community of Kilimatembo constructed terraces and planted trees and grasses to reduce runoff and stabilize the soil. 


Pre-project consultation and village sensitization meetings held during which the following decisions were made:

  • Village government should formulate by-laws that will enforce implementation of soil and water conservation activities in the area as part of this project implementation.
  • Each sub-village would select 4 people to form a pegging team.
  • Each pegging team should prepare an action plan.
  • The village chairperson with assistance from village agricultural extension officer would supervise and monitor the pegging teams’ activities.
  • Each pegging team should have its own contour layout equipment.
  • Village agricultural extension officer appointed to be the project coordinator.
  • 100 farmers identified for participation in the project

Purchase and distribution of equipment

Training of sub-village pegging teams: Training of contour layout pegging team members was conducted for two days from 29 – 30 December 2016. The first day was in class for theoretical aspects of the technique and the second day was practical experience in the field.

Layout of contours/terraces: The sub-village pegging teams laid out contours on farms identified by sub-village leaders and each farm owner was responsible for construction of contour bunds and planting of vegetative materials.

Planting of vegetative materials: A total of 9700 seedlings of various tree species and 10 lorry trips of elephant grasses (Pennisetum purpureum) were distributed to and planted by farmers at Kilimatembo village. During this activity, SFS students participated in preparation of tree seedlings at the tree nursery and planting these vegetative materials in the farms as part of community services. Due to high demand of tree seedlings, additional 3700 seedlings were requested and supplied from the Ngorongoro Conservation Area nursery. The high demand for tree seedlings was due to an increase in the number of participating farmers not originally planned to participate in the pilot project.

Important Considerations

-Because trees planted along the contours have other benefits once they grow such as harvesting for timber, there is potential for contested ownership of the trees planted in farms owned by large families. To avoid potential family conflicts in the future, tree ownership and sharing of future benefits derived from the trees should be clearly discussed and agreed upon at the outset of the project.

-The agricultural extension officers must increase education with the farmers about the importance of trees for terrace success. Increased education and awareness will promote the planting of saplings in the correct locations along the terraces rather than around people’s homes.

-Distribution of trees to test farmers should be done with consideration of the timing of rains in order to ensure rainfall occurs shortly after the trees have been planted. 



  • 47,197 meters of ground contouring applied to a total of 65 farms, comprising 199 acres of land 
  • 9,700 seedlings of various tree species were planted over the course of the project. 

Capacity building


Statistical analysis of yield data collected from the treatment (project) farms, control farms and sub-control farms one year after project implementation produced mixed results. Yields in the treatment farms were not found to be higher than control farm yields. However, several factors may have contributed to this outcome:

  • the average slope of treatment farms was much greater than control farms, which can impact yield
  • it was discovered later that many participating farmers planted their trees near their homes rather than along the terraces where they were intended to stablize soil
  • planted tree seedlings only achieved a 30% survival rate, further detracting from the soil stabilization effect
  • the differences in average elevation between the treatment and control plots may effect precipitation, which could impact yield
  • the small sample size may have impacted results

In order to acheive desired outcomes, the above factors should be taken into consideration in the design and implementation of future projects of this kind. 


Overcoming deteriorating water resources in Hoima, Uganda

In Kihigwa, people have always depended on open springs to collect their water. During Climate Crowd interviews, community members explained that these sources have become more prone to drying up as droughts become more severe, and more susceptible to contamination from surface runoff generated by more intense storms. Local people have experienced an increase in prevalence of water-borne illnesses and an increase in the amount of time needed to fetch water during drought. In response to these challenges, the community of Kihigwa worked with a local Peace Corps volunteer to identify the most important water sources in the village. Using funds provided through Climate Crowd, four key open water springs in Kihigwa were transformed into protected shallow wells and springs. These actions have ensured that the water sources are protected from contamination at all times while also providing a stable flow of water all year round even during drought.

1) Community Action Planning: Immediately following a participatory rural appraisal, the community and project facilitators wrote a community action plan (CAP) to provide direction and structure to the project. This was also done to ensure that the community had a key role in the planning process in order to promote their ownership of the project.

2) Surveying of the water resources: Within the limits of Kihiwa Village there are ten springs and four shallow wells. Water resource engineers were brought to Kihigwa to survey each of the sources. This was necessary to determine (1) the usage rates of the sources, (2) the feasibility for improvement of various sources, and (3) to develop solutions for improving the sources. Surveying revealed that to fully improve all of the sources was not feasible with limited funding and resources. Consequently, a portion of the sources believed to benefit the community the most if improved were selected. All four shallow wells were selected for repairs and three key springs were selected to be protected. Partial protective measures were planned for the remaining seven springs.

3) Meetings with each water source committee and their users: Meetings were held for the committees and users of each source in order to establish management plans to ensure the physical integrity of the sources and the surrounding areas is maintained. During these meetings, fee collection systems were established or reestablished for each water source

4.) Improve water sources: 

Shallow well repairs - Repairs required the technical skills of an engineer to replace faulty or broken parts

Spring protection - Project facilitators worked with community members to discuss solutions for mitigating contamination including developing plans to move agricultural activities away from water sources, build protective barriers around the sources, plant native trees and shrubs to reduce sedimentation, physically remove silt, debris, and other contaminants from the sources, and ensure that water can flow freely to prevent stagnation.


Important Considerations:

For larger communities, deciding on a central location for the source (or sources) can be a sensitive topic. Some members of the community will inevitably benefit from the new source more than others based on where it is positioned. Consequently, it is important to reach a consensus with the entire community before the source is established.  

For a water infrastructure project such as this, a plan needs to be established to ensure each water point continues to function properly following  project completion. In Kihigwa, water source committees were established to develop fee collection and maintenance systems for each source. Key questions for consideration while establishing a fee-based system include: 1) who, when, and where will fees be collected?; 2) what will the fee amount be and what amount is feasible for community members with limited financial means?; and 3) how will the funds be protected (i.e. how will committees ensure fees go towards there intended use in full)?

Recycling plastic bottles to build rainwater harvesting tanks

The town of Mbale in Eastern Uganda faces worsening water scarcity as droughts become more severe and rainy seasons shorter in a changing climate. In response to these challenges, WWF funded the Ichupa Upcycle project. Designed and led by former Peace Corps volunteer Michal Matejczuk, the project uses discarded plastic bottles collected from around the community as raw material for constructing a rainwater harvesting system that can store water for use during dry spells. 


(for one 2000L-3000L Water Tank):

Plastic bottles: >600 (1.5L) or >2,100 (500mL)

Cement: 20-25

Sand: two 8ft flatbed truckloads

Chicken wire/wire mesh (three 8ft X 4 ft)

Foundation (Bricks/Cement/Aggregate/Sand – depends on ground type)

Tank lid (Plastic or Concrete – depends on preference)

Drainage pipes, taps, valves, etc. (depends on number of outlets)

Tools: spades, shovels, buckets, hoes


The following provides an overview of activities undertaken for the completion of this project. For a more detailed, step-by-step guidance on the construction process, click the download button located at the bottom of this page.

1. Identification of optimal locations: based on need, access, security, etc. (see manual for list of criteria)

2. Preparation of construction sites: cleared sites of weeds and debris, leveled off the land where necessary, and built bases to support the tanks

3. Procurement and preparation of plastic bottles: community clean-up day held to gather plastic bottles (with caps). Sorted bottles based on size. Children from local school helped pack bottles with dirt, small pebbles and even plastic debris.  

5. Tank construction: For each tank, bottles were arranged in a circle with the caps facing outward. Cement was applied between bottles and between each layer.  

To prevent the structure from buckling or cement from seeping out, no more than 3-4 layers were completed at a time, followed by 6-8 hours of wait time.

6. Finishing touches: Once desired height was reached, spaces were made near the bottom to accommodate a drainage pipe and spigot. Structures were allowed to dry for several days followed by application of chicken wire and additional layers of cement around the inner walls.

Spigots and drainage pipes affixed, and lids placed on top.

7. Attachment to gutters: Once tanks were completed, gutters were added to nearby buildings and attached to the tanks.


Key considerations:

Water must be treated by filtration, heating it to 212F/100C for three minutes, or by adding a chemical solvent. Post a sign with this information in the local language if system is publicly accessible.

Rainwater harvesting in Njombe, Tanzania

In the village of Idunda in Tanzania people are experiencing increasingly unpredictable rainfall, making it all the more important for the community to manage their water resources strategically.Through a grant from WWF’s Climate Crowd program, a local volunteer teamed up with teachers, students and families from the community to construct a new hand washing station and rain capture and storage system at Idunda's primary school. 

The rain catchment system diverts roof runoff to a water storage tank and any overflow to an infiltration pond to minimize soil erosion and replenish groundwater.  The stored water is piped to the hand washing station located between the bathrooms and classrooms such that students can conveniently wash their hands before returning to class. Following construction and installation, teachers led a School Water Day, during which students participated in hands-on activities to learn about climate change, water conservation, and appropriate use of water for personal health and hygiene.

Total completion time: 2.5 months

  • Initial project planning and design
  • Digging of waterline trenches and preparation of infiltration pond
  • Purchase and transport of construction materials
  • Rainwater gutter installation


  • Hand washing station construction and plumbing installation
  • Training of trainers for Itanana School "Water Day"
  • Implementation of Itanana School "Water Day"


Important considerations

  • Since villagers provided much of the work that went into the project at the school, it’s recommended that constructions schedules be planned jointly with the school and village committee
  • Attend local plumbing/hardware store with community counterpart with draft budget in hand to ensure expected costs are accurate
  • Ensure a plan is in place for project maintenance. Idunda Village collects an annual tax to maintain the community’s water infrastructure, which now includes any necessary improvements made to this project. School teachers have agreed to maintain the supply of soap for the handwashing station
  • Note: water is not suitable for consumption unless additional filtration and treatment is installed. Ensure proper signage is posted to alert users of this. 


Direct outputs

  • Installation of 80 meters of rain harvesting gutters
  • Construction of an efficient 6-faucet hand washing station
  • Construction of an infiltration pond for water overflow during the rainy-season in order to prevent erosion

Capacity Building

Students trained on proper hand washing, rainwater harvesting, water sanitation, water conservation, and climate change. These skills and lessons will help keep themselves healthy and hopefully will help inform them later in life about how to conserve water and their environment. During the gutter installation many of the older students learned some basic carpentry skills as well.

  • Girls, age 14 and under: 36
  • Boys, age 14 and under: 46


Quizzes administered before and after the School Water Day indicate that the majority of students who participated demonstrated an improved understanding of key concepts related to climate change, water management and hygiene following the event. Children now have access to improved water access for sanitation:

  • Girls, age 14 and under: 36
  • Boys, age 14 and under: 46



Installation of weather stations around the world

We are installing a global network of weather stations and automating upload of data collected to the cloud. So far, we have installed weather stations in Tanzania, Zambia, Cambodia, Australia and the USA. Data from these stations can be viewed on the Climate Crowd homepage.

Constructing an irrigation system in Uganda to address unpredictable rainfall

Residents in and around Mayuge district have noticed especially dramatic changes in climate in recent years, including long periods of drought and excessive heat, punctuated by extreme rainfall and accompanying soil erosion. Additionally, the timing of the seasons have become much less predictable. These changes have had devastating effects in a society where nearly 90% of people make a living primarily through rain-fed agriculture.

To combat these changes, WWF partnered with a former Peace Corps volunteer, Sam Strimling, to support a community-wide effort to construct a much-needed irrigation system to support local farms.  This project provided local farmers with the materials and training needed to build storage tanks sufficient for irrigating two acres of farmland. 



  • Sand
  • Wood poles
  • Wire mesh nets
  • Iron bars
  • Cement
  • Softwood planks
  • Nails
  • Binding wire
  • Bricks
  • A pipe used to capture run-off from the existing borehole (also filtering into the large harvesting tank),
  • A gas-powered water pump
  • 150-meter hose to distribute water to the crops.



Construction began at the end of the dry season to ensure the system could begin collecting rainwater soon after completion. Approximately 60 members from the community came out each day over the course of one week to assist with procurement of materials, cement mixing and transporting of bricks. Additional labor was contracted to complete more technical work including brick laying and plaster application. Watch video


Key considerations:

  • With any water collection project, ensure storage tank is covered to prevent mosquitos from using it as a breeding site
  • Do not use harvested water for drinking unless properly treated


Direct outputs:

  • 1 large (12ft x 12ft x 13ft) water storage tank,
  • 1 smaller (4ft x 3ft x 2ft) attached tank to be used for purposes of capturing run-off and filtering out sediment before flowing into the larger tank
  • Pump and hose system to transport water from tanks to crops

Capacity building

Number of individuals who received training and participated in project completion:

  • Males, 15 and older: 117
  • Females, 15 and older: 32

Impact on farming

To date, farmers have expressed their satisfaction with the system, which they've already put to use. Currently they are using irrigation made possible by the project to grow pumpkins and passion fruit during the dry season, something that was only possible during the wet season in years past. Growing these crops at this time of year also means they can fetch a higher price at market, thereby boosting household income.

Since completing this Climate Crowd project, Sam has gone on to start her own non-profit to replicate this project model at other sites in Uganda. 

Restoring a watershed to help communities cope with drought

A series of Climate Crowd interviews conducted by our partners from the Institute for Ecological Research (IPE) revealed that changing rainfall patterns and drought have had serious impacts on people and wildlife living in Brazil’s Pontal do Paranapanema region. To combat these changes, WWF and IPE worked together on a project to improve the resilience of a local watershed and improve habitat connectivity through community-based reforestation.

Once mature, the newly planted hectare of tropical forest will provide direct benefits to people such as water provision services, decreased damage from wind storms and protection from soil degradation and erosion. The new forest will also contribute to important habitat corridors for local wildlife including the endangered black lion tamarin, as well as ocelots, jaguars, monkeys, armadillos, etc.  and create a buffers zone for the The Black Lion Tamarin Ecological Station.

Completion of 31 Climate Crowd surveys in communities living in the Pontal of Paranapanema region of Brazil’s state of Sao Paolo

Participatory planning of the area to be restored (a 1 hectare parcel of degraded land bordering the Black Lion Tamarin Ecological Station), including involvement of the manager of the protected area, the local communities, members of the watershed committees, local universities, schools and NGOs


Hiring of local contractors to conduct soil preparation using plowing, sorting and manual removal of grasses/other exotic species, soil pH monitoring and other measures in project site

Lectures and training workshops conducted in communities bordering the protected area


Sourcing of seeds from local nurseries


Planting of seedlings at the start of the rainy season through community mobilization:  Trees planted include native species and pioneers of rapid growth (50% pioneer and 50% non-pioneer species) and were spaced 2 meters apart, with 2.5 meters between each row


Participatory monitoring to monitor the healthy growth of planted trees, in additional to ongoing maintenance including site visits to perform ant (Atta spp.) control, prevent invasion of grasses, and replant more than 200 trees to replace those that did not survive



Important considerations

With any restoration project, continued maintenance post-planting is necessary to ensure seedlings reach maturity. A plan must be in place to manage encroachment of invasive plants and impacts from pests, for example.


Direct Outputs:

2000 tree seedlings (48 native species) planted, covering 1 hectare

Capacity Building:

Over 600 people from local community trained on local protected area and tree planting


Immediate project outcomes include:

  • Economic benefits for the local community through the contracting of labor for soil preparation, and acquisition of native tree seedlings from local nurseries
  • Increased awareness of socio-environmental issues of the region through involvement of various social segments of the local community.
  • Strengthening of partnerships with government institutions, residents, NGOs, universities, river basin committee, companies, conservation units and schools

Ongoing monitoring efforts will measure tree growth and provide further insights on project outcomes over the next several years.


Teaching students how to plan and implement small scale adaptation projects

Families in Santa Lucia, Mexico are struggling to cope with hotter summer temperatures, colder winter temperatures, erratic rainfall, and pests, all of which have affected crop production. To address these growing concerns, Peace Corps Mexico has teamed up with local teachers to instruct middle and high school students and the broader community on climate science and how to develop interventions that boost local resilience to the effects of climate change including through the construction of small-scale greenhouses and xeriscaped gardens. 


Plastic bottles

Non-recyclable/non-compostable refuse

Cob (mixture of soil, grass and sand)





Pick axe


Bag of cement



Bags of calcium

River rock

PCV tubing

Greenhouse film


Project leaders conducted workshops on the basics of climate science for three groups of middle school students (ages 12-14) and one group of high school students (ages 17-20). Topics included the greenhouse effect, general impacts of climate change globally, and what can be done locally to help mitigate and adapt to climate change.

Intervention-specific workshops were also conducted for each group explaining the environmental benefits of each intervention and why they are important in the context of climate change. Instruction will also be provided on the basic steps of project planning. Students were tasked with submitting a report on their respective intervention.

Middle school students will be involved with implementing each of the three interventions at the school. In addition to assisting with construction of a "hoop house" garden at the school, the high school students will also assist with constructing hoop houses at six households within the local community. 

Hoop houses are a small-scale and inexpensive type of greenhouse. They use PVC tubing or rods and greenhouse film to cover garden beds. They help protect plants from freezing temperatures, heavy rainfall, and insects.

Xeriscape gardening is a type of landscaping technique suitable for arid climates that uses rocks and plants that require minimal water to survive.  

Eco-benches will be built using ‘eco-bricks’ that reutilize plastic bottles filled with non-recyclable or non-compostable refuse from homes, schools and public spaces. Instead of using cement to hold the bricks together, a mixture called cob (a combination of soil, sand, and grass) is used. Cement will be applied on the outside to create a waterproof layer.

A  project planning workshop will be conducted at the end to review what the students have learned over the course of the project execution phase and how to evaluate what was accomplished. Workshops and project activities will be integrated into the school curriculum to ensure the project continues to build capacity for students in the coming years.




Direct outputs (anticipated):

  • The successful construction of 2 eco-benches, 2 hoop gardens and 1 xeriscape garden on school grounds
  • Construction of 6 hoop gardens at the homes of community members

Capacity Building (anticipated):

Number of youth with increased knowledge and appreciation of climate change adaptation:

  • 86 women and girls
  • 92 men and boys 

Impact (anticipated):

Improved survival of crops grown in hoop greenhouses

Rainwater Harvesting System for School Garden Irrigation in Guatemala

After attending a Climate Crowd training in the fall of 2018, a Peace Corps volunteer working in rural Guatemala conducted interviews in his host community of San Antonio Ilotenango to learn about the local impacts of climate change. Community members expressed that rainfall had weakened in recent years, and the dry season had become longer and more severe. To cope with the impacts on water availability and poor crops yields, the volunteer is working with local partners to establish a school garden and rainwater catchment system to support irrigation during prolonged dry periods.
