| vii EVALUATING SUSTAINABILITY AND FOOD SECURITY OF PEASANT FARMING SYSTEMS IN MESOAMERICAN HIGHLANDS Summary During the last decades, sustainable agriculture has been the subject of considerable academic interest and debate, not only in conceptual terms, but also in methodological ones. The persistence of high levels of environmental degradation and food insecurity in many regions has led to new initiatives focused on revitalizing peasant agriculture and renewed discussions of the role of sustainable agriculture as an engine for development, environmental conservation and poverty alleviation. Therefore, to assess mountain farming systems, we must consider food dimension and taking into account the specificities of the mountain systems as the foundation of sustainability. When evaluating contribution of technological and management alternative proposals in achieving sustainability and food security for peasant farming systems in Mesoamerican highlands, three research questions arise: ? Is sustainability of peasant-farming systems being evaluated taking into account climate variability, participation of farmers and temporal dynamics? ? Can we rescue common trends in these systems and extrapolate the results to other areas? ? What alternative proposals that have been conducted are unequivocally positives? | |
