SofoNic – Environmental problems (part 2)

Oxana Delgadillo & Livio Gonzalez   

"Remember, we have not inherited the world from our ancestors,
rather, we have received it on loan from our children.”

Drought, exhausted or infertile soils, high costs of agricultural inputs (fertilizer and pesticides), along with low prices for farm products, intensified by the limited resources of the producers leads to inefficient use of these inputs or agricultural practices, resulting in low levels of productivity and profitability. Other difficulties are the high incidence of plagues and diseases, as well as the scarcity of feed for livestock during the dry periods.

CIDEM – Involving students in research

Guided by a competent and engaged team of professors they have been delving into various themes concerning alternative cement, solid fuel bricks, MCR, and adobe.

The chain of commercialization

It is difficult because of time and distance to meet directly, so the EcoSouth Network in Ecuador permanently keeps up individual contact with most MCR producers. These producers are located in disperse places, although in populated areas, so the main via of communication is the telephone, as e-mail access is quite limited.

Filmed in Nicaragua and Salvador, it shows production and application and gives a summary overview of those two materials that have a relatively small ecological footprint and have widely proven to be sustainable in the three classical dimensions ecology, economy and social acceptance.
