La agricultura campesina sigue siendo una práctica muy importante en México, sin embargo no se presenta de manera homogénea, existe una diversidad de manejos que repercuten en los rendimientos de la cosecha y en el mantenimiento de la biodiversidad. En tiempos recientes, dada la excesiva utilización de pesticidas y al aumento de los monocultivos, l...

Title: Sustainability assessment of subsistence agriculture in San José de Cusmapa, Nicaragua Sustainability evaluation of peasant agricultural systems is becoming a global challenge due to the fact that family farms produce over 70% of food supply. In rural areas of Nicaragua family farm involve about 49% population and the subsistence agricultur...

Smallholder agricultural systems have an important role in world food production. Agricultural smallholders in highland areas of the Mesoamerican dry-corridor are central to improve farming systems. The key issue is that the subsistence smallholders are joint producer-consumers, with insufficient food production due to extreme environmental and wea...

The Americas have a long history of managing fermentation to produce food and beverages. Because maize is such a widespread and culturally important food resource, it has historically been a basic substrate for fermentation by the cultures that inhabit these areas. Fermented maize beverages (FMB)are components of food systems, are present in ritual...

La adaptación a la sequía es objeto de debate e interés desde diversos enfoques y ámbitos geográficos. En este contexto es importante que, en las áreas naturales protegidas, se promuevan acciones que, sin descuidar la conservación, busquen mejorar la adaptación de sus habitantes frente a los cambios en el patrón de las lluvias y degradación de los...

The milpa agroecosystem is an intercropping of maize, beans, squash and other crops, developed in Mesoamerica, and its adoption is widely variable across climates and regions. An example of particular interest is the Yucatan Peninsula in Mexico, which holds highly diverse milpas, drawing on ancestral Mayan knowledge. Traditional milpas have been de...

What people eat affects public health and human wellbeing, agricultural production, and environmental sustainability. This paper explores the heterogeneity of food consumption patterns in an ecologically and culturally diverse country. Using a latent class approach (which creates clusters of individuals with homogeneous characteristics), we analyse...

La pérdida y degradación de suelos debe ser estudiada mediante prácticas transdisciplinarias que integren diferentes saberes y conocimientos, esto requiere de nuevos enfoques y de la combinación de métodos diversos. En este capítulo presentamos un estudio de caso sobre coevaluación de la pérdida de suelos en cuatro municipios de la Costa Grande de...

Tackling the environmental impacts of food systems can play a crucial role in achieving urban sustainability. Robust accounts of urban food supply must inform policymaking. Current research on urban food supply often relies on extrapolating national data sets to the urban scale, obscuring the diversity of food consumption patterns across regions an...

BACKGROUND Maize tortillas are the staple food of Mexico and their consumption contributes to preserving the gastronomic patrimony and food security of the population. The aim of the present study was to generate a reference sensory profile for different types of tortillas and to evaluate the effect that these sensory characteristics have on consum...

Certain components of global food security continue to be threatened. Globalization has impacted food patterns, leading to greater homogenization of diets and the standardization of processes of food transformation, both in the countryside and in the cities. In Mexico, this has led to a drop in the use of native corn landraces and in the value asso...

En el antropoceno es imperativo que cada acción humana esté armonizada con el cuidado del ambiente. En los países andinos, el manejo de los recursos naturales en los territorios rurales y las áreas protegidas, recae mayoritariamente sobre campesinos e indígenas, poblaciones que a su vez, registran altos índices de pobreza y marginalidad. Para evalu...

Food and Nutritional Security (FNS) is still an outstanding problem, and rural areas of Guatemala demonstrate this by an increase in the undernourished population from 1.4 million in 1991 to 2.5 million in 2014. Some FNS programs were developed in the past, and our research evaluates the following: (1) the critical points perceived by farmers relat...

Farmer field schools (FFSs) emerged in response to the gap left by the worldwide decline in agricultural extension services. With time, this methodology has been adapted to specific rural contexts to solve problems related to the sustainability of peasant-farming systems. In this study we draw upon empirical data regarding the peasant-farming syste...

En el marco del avance cualitativo que traza la Agenda 2030 para el Desarrollo Sostenible en la comprensión y las aspiraciones globales, uno de los grandes retos de la humanidad es dar respuesta a la creciente necesidad de armonizar las acciones humanas con el cuidado del ambiente y asegurar su sostenibilidad. Estos grandes retos demandan nuevos cu...

Durante las últimas décadas, la agricultura sostenible ha sido objeto de estudio y de debate académico, no sólo en términos conceptuales, sino también en términos metodológicos. La persistencia de la inseguridad alimentaria y el deterioro de los recursos naturales en muchas regiones del mundo, ha provocado el surgimiento de numerosas iniciativas ce...

The concept of sustainability implies a long-term relationship between human been and nature. Sustainable production systems are those systems capable of remaining in the time since they promote the conservation of natural resources, social capital and generate enough economic rents to support themselves. Growing vine and wine activities in Mendoza...
