Sustento assists the public and private sectors in Latin America to make decisions based on natural resources security, particularly water and productive land.  The word “sustento” refers to “livelihood” or “sustenance” in Spanish, and underscores the fact that humanity´s livelihood is dependent on the limits of a single, finite Earth.

What we believe:

Sustainability needs to be quantitative and objective.

All sectors of society (governments, private sector, NGOs, and individuals) have a vested interest in living within
the physical limits of one Earth.

Scientifically based footprint accounting and assessments are intuitive and practical approaches to quantify
