Agroecology can promote climate change adaptation outcomes without compromising yield in smallholder systems

Sieglinde Snapp Yodit Kebede Eva Wollenberg (2023, [Artículo])

A critical question is whether agroecology can promote climate change mitigation and adaptation outcomes without compromising food security. We assessed the outcomes of smallholder agricultural systems and practices in low- and middle-income countries (LMICs) against 35 mitigation, adaptation, and yield indicators by reviewing 50 articles with 77 cases of agroecological treatments relative to a baseline of conventional practices. Crop yields were higher for 63% of cases reporting yields. Crop diversity, income diversity, net income, reduced income variability, nutrient regulation, and reduced pest infestation, indicators of adaptative capacity, were associated with 70% or more of cases. Limited information on climate change mitigation, such as greenhouse gas emissions and carbon sequestration impacts, was available. Overall, the evidence indicates that use of organic nutrient sources, diversifying systems with legumes and integrated pest management lead to climate change adaptation in multiple contexts. Landscape mosaics, biological control (e.g., enhancement of beneficial organisms) and field sanitation measures do not yet have sufficient evidence based on this review. Widespread adoption of agroecological practices and system transformations shows promise to contribute to climate change services and food security in LMICs. Gaps in adaptation and mitigation strategies and areas for policy and research interventions are finally discussed.

Militancia partidaria y toma de decisiones en el Movimiento Regeneración Nacional.

Mariela Díaz Sandoval Alberto Espejel Espinoza (2018, [Artículo])

The purpose of the article is to show a qualitative approach to the opinion of the militancy on decision¿making inside the National Regeneration Movement (Morena). Hence, the paper accounts for an actor, of whom little evidence has been provided, in the studies on intra¿democracy: the militant. In that sense, the questions that guided the research were: Who makes the major decisions with in Morena? What role do the militants have when it comes to selecting leaders and candidates? What does the militant think about the way in which are made with in the party? By conducting in¿depth interviews and document analysis, the main findings show the concentration of power in Morena, both statutory level and in the partisan reality. Coupled with an active and dissatisfied militancy, but at the same time justifies the concentration of power in Andrés Manuel López Obrador.

Diseño y evaluación bioclimática para Museo del Agua en el municipio de Tecámac, Estado de México

Luis Roberto Gómez Luna (2023, [Otro, Trabajo terminal, especialidad])

155 páginas. Especialización en Diseño Ambiental.

El propósito de ésta idónea comunicación de resultados (ICR) es compartir la metodología aplicada para la aplicación de diseño bioclimático desde el diseño de un proyecto nuevo además de aplicarla en un museo para el organismo público descentralizado para la prestación de los servicios de agua potable, alcantarillado y saneamiento (ODAPAS) con la temática del agua desde su tratamiento, usos, historia, y la parte que conforman en la cultura de Tecámac. Se explica a detalle las estrategias aplicadas para lograr el confort acústico, lumínico, térmico, y de ventilación, especificando la metodología del diseño bioclimático aplicada, así como los resultados de estas.
