BOLIVIAN COUNTRYSIDE
• The shortage of water caused by droughts and climatic changes causes people in rural areas to consume non-potable water. This generates health issues causing serious consequences in the communities:
• Diseases linked to non-potable water, like acute diarrheal diseases (ADDs), endanger the life of children under 5.
• Diseases linked to non-potable water have heavy costs in terms of time and money for the families, reducing their capacities in adaptation to climate change.
• Good health is necessary for a worthy and productive life. Diseases prevent adults from attending work and prevent children from attending school and prospering.
• For these reasons and more, it is important for families to have a method of purifying water. Our analysis showed that the best way for these families to consume potable water is to boil it using solar cookers.

WHY SOLAR COOKERS? (IMAGE 1)
ADVANTAGES
With solar cookers, water can be boiled to be safe for human consumption. This method has many environmental advantages for the municipalities of Betanzos, Tarabuco and Ocuri, but it also improves the living conditions of families:
1. Solar cookers do not emit greenhouse gases, thus preserving the environment. Each solar cooker reduces CO2 emission by 0.69 tons per year.
2. Solar cookers use the sun as their only fuel, therefore families do not need to invest efforts in felling trees and shrubs (which saves them about 15 hours per week in time and effort).
3. The security of women is increased since they do not have to leave their homes in search of firewood.
4. Air quality is improved within households since firewood is used less in enclosed spaces. In this way, the health of the whole family is improved and Acute Respiratory Infections (ARIs) are reduced.
5. Since the need of firewood is reduced, there are more trees to capture CO2 and purify the air. Also, with the help of trees, rainwater is better captured by the underground reservoirs. A solar cooker can save around 100 trees in 15 years.
6. Since there is more rainwater underground, families' resilience to climate change is increased as there is more water available during the year.
7. Solar cookers do not need to be supervised, therefore women (usually in charge of preparing the food) can devote their time to other productive interests and activities.
8. The economic costs of families in firewood or gas are reduced from 35% to 40%.
9. Solar cookers are safer than firewood since there are fewer fire risks.
10. Solar cookers are low cost and require little maintenance.
11. Solar cookers can go up to 200 degrees Celsius and water is safe to drink after 3 minutes at 65 degrees Celsius.
12. The proposed solar cookers have more than 20 years of useful life.
Other projects in the Department of Oruro have succeeded with solar cookers (https://asointiillimani.wordpress.com/).

ACTIVITIES AND BUDGET
To present this crucial and complementary component, Sumaj Punchay wants to run a pilot project to study the feasibility of solar cookers and to determine if the targeted communities approve of it. To do this, Sumaj Punchay must execute experiences to verify the technical and social acceptance of the solar cookers in the community. All details are included in the Excel document attached.

DETAILED BUDGET
In addition to the material for the construction of the kitchens, technicians are needed to instruct people in the construction of the kitchens, tools are needed, training so that people know how to use the kitchens and how to boil water, training in best practices safe water management in the home and hygiene, fences to protect the kitchens from animals, pots for the preparation of food and appropriate containers to store boiled water. When this component is integrated into a project, families assume 30% of the construction costs of solar cookers and build them themselves through training courses. (IMAGE 2)
