Description of the project: The project benefits 2,454 women
(and their families) of the indigenous Mayan communities in
Yucatan, Mexico. Energy security, food sovereignty and agricultural
sustainability are achieved through an anaerobic digester, treating
animal waste, that produces biogas and biofertilizer. Women
get training on the use, management and maintenance of the
biodigester. The digester reduces soil and water contamination,
airborne pathogens causing diseases, and provides energy security.
The biofertilizer, combining the functions of fertilizer, pesticide
and soil regenerator, aids food sovereignty. The project promotes
women’s capacities for inclusion in decision-making at all levels.
Climate impact: Project achieves over 99% pathogen reduction.
Biogas displaces liquid petroleum gas and woodfuel.
Organic fertilizer displaces synthetic fertilizers, eliminating environmental
impact (775 MT CO2/year). The system, designed with
local materials, requires low maintenance. No need for external
technical assistance, repairs, fossil fuels, fertilizers; pesticides are
eliminated. Children and youths learn to promote sustainability
while adults are trained in forest management.
Gender impact: Women are healthier and are able to take up
more income generating activities, such as embroidery. They
have extra time for family and for themselves, or participating in
community activities. Other impacts include: reduction of burden
of cleaning pig waste; significant health impacts from substitution
of woodfuel and plastic; more spare time (previously
used to collect wood); more varied, nutritious and organic diet
with own produce; women are able to participate in decisionmaking
Scalability / replicability: The project is easy to replicate and
upscale. Trained users handle and teach others how to install,
manage and repair the system. It uses easily available material.
The educational component includes a children’s tale to make
the technology more understandable and easily transmitted.
The project works closely with community members; the technology
is specially designed for harsh rural conditions. The smallscale
biodigester is a high quality durable good, easy to package,
distribute and install.
