"En los estados del sur de México, entre un 25% y un 55% de los hogares dependen de la leña para cocinar, lo cual trae consecuencias en el ambiente, el desarrollo y la salud. No obstante, el conocimiento de estas consecuencias y la migración hacia combustibles modernos ha permanecido relegada de las políticas de desarrollo. En este trabajo, partiendo de una descripción del panorama de uso de leña en el país y su importancia como fuente de energía, se presenta una aproximación para estimar ahorros en emisiones de CO2 logrables por la transición a gas licuado a presión (GLP), los cuales pueden alcanzar 3.14 Mt CO2e, 26% menos que el escenario base. Se finaliza con una discusión de la transición hacia combustibles modernos, las barreras que la impiden y los logros y fallos de la distribución de estufas ahorradoras de leña, la principal iniciativa gubernamental para aliviar el consumo de leña en el país."
"Between 25% and 55% of households in southern Mexico depend on biomass for cooking, which carries serious consequences on the environment, development and health. In spite of the knowledge of these consequences, transition from biomass to modern fuels has remained outside energy and development policies. In the present work, after describing the panorama of fuelwood use in the country and its importance as an energy source, an approach is presented for estimating CO2 savings achievable by transition to pressurized liquefied gas (LP). These savings can reach 3.14 Mt CO2e, 26% less than the baseline scenario. At the end we discuss on the transition to modern fuels in Mexico, the barriers that hinder it and the achievements and failures of the distribution of fuelwood saving cookstoves, as the only and most important governmental initiative to alleviate biomass use, comparing it with other priorities in the government's agenda."

Con la finalidad de impulsar el desarrollo de la región sureste de México, la actual administración del gobierno federal se ha propuesto la ampliación de la red nacional de gasoductos hacia esa zona del país, con el fin de suministrar energía a los megaproyectos de la región. No obstante, estas obras presentan actualmente retrasos, evidenciando la necesidad de metodologías de gestión que permitan solucionar este problema de raíz. Una de las metodologías más prometedoras en esta materia es la front-end loading (FEL), ampliamente aplicada en el sector extractivo y energético. El propósito del articulo estriba en evaluar la posibilidad de aplicar la metodología FEL a los proyectos de expansión del Sistema Nacional de Gasoductos en el sureste mexicano.
To boost the development of the southeast region of Mexico, the current federal government administration has proposed the expansion of the national gas pipeline network to this area of the country, to supply energy to the region's mega-projects. However, these projects are currently experiencing delays, demonstrating the need for management methodologies to solve this problem at its root. One of the most promising methodologies in this area is front-end loading (FEL), which has been widely applied in the extractive and energy sector. The aim of this paper is to evaluate the possibility of applying the FEL methodology to the expansion projects of the National Gas Pipeline System in the southeastern México.

The future of South Asia’s major production system (rice–wheat rotation) is at stake due to continuously aggravating pressure on groundwater aquifers and other natural resources which will further intensify with climate change. Traditional practices, conventional tillage (CT) residue burning, and indiscriminate use of groundwater with flood irrigation are the major drivers of the non-sustainability of rice–wheat (RW) system in northwest (NW) India. For designing sustainable practices in intensive cereal systems, we conducted a study on bundled practices (zero tillage, residue mulch, precise irrigation, and mung bean integration) based on multi-indicator (system productivity, profitability, and efficiency of water, nitrogen, and energy) analysis in RW system. The study showed that bundling conservation agriculture (CA) practices with subsurface drip irrigation (SDI) saved ~70 and 45% (3-year mean) of irrigation water in rice and wheat, respectively, compared to farmers’ practice/CT practice (pooled data of Sc1 and Sc2; 1,035 and 318 mm ha−1). On a 3-year system basis, CA with SDI scenarios (mean of Sc5–Sc8) saved 35.4% irrigation water under RW systems compared to their respective CA with flood irrigation (FI) scenarios (mean of Sc3 and Sc4) during the investigation irrespective of residue management. CA with FI system increased the water productivity (WPi) and its use efficiency (WUE) by ~52 and 12.3% (3-year mean), whereas SDI improved by 221.2 and 39.2% compared to farmers practice (Sc1; 0.69 kg grain m−3 and 21.39 kg grain ha−1 cm−1), respectively. Based on the 3-year mean, CA with SDI (mean of Sc5–Sc8) recorded −2.5% rice yield, whereas wheat yield was +25% compared to farmers practice (Sc1; 5.44 and 3.79 Mg ha−1) and rice and wheat yield under CA with flood irrigation were increased by +7 and + 11%, compared to their respective CT practices. Mung bean integration in Sc7 and Sc8 contributed to ~26% in crop productivity and profitability compared to farmers’ practice (Sc1) as SDI facilitated advancing the sowing time by 1 week. On a system basis, CA with SDI improved energy use efficiency (EUE) by ~70% and partial factor productivity of N by 18.4% compared to CT practices. In the RW system of NW India, CA with SDI for precise water and N management proved to be a profitable solution to address the problems of groundwater, residue burning, sustainable intensification, and input (water and energy) use with the potential for replication in large areas in NW India.

Women, economic resilience, gender norms in a time of climate change: what do we know?
Cathy Farnworth Anne Rietveld Rachel Voss Angela Meentzen (2023, [Artículo])
This literature delves into 82 research articles, published between 2016 and 2022, to develop a deep understanding of how women manage their lives and livelihoods within their agrifood systems when these systems are being affected, sometimes devastatingly, by climate change. The Findings show that four core gender norms affect the ability of women to achieve economic resilience in the face of climate change operate in agrifood production systems. Each of these gender norms speaks to male privilege: (i) Men are primary decision-makers, (ii) Men are breadwinners, (iii) Men control assets, and (iv) Men are food system actors. These gender norms are widely held and challenge women’s abilities to become economically resilient. These norms are made more powerful still because they fuse with each other and act on multiple levels, and they serve to support other norms which limit women’s scope to act. It is particularly noteworthy that many institutional actors, ranging from community decision-makers to development partners, tend to reinforce rather than challenge gender norms because they do not critically review their own assumptions.
However, the four gender norms cited are not hegemonic. First, there is limited and intriguing evidence that intersectional identities can influence women’s resilience in significant ways. Second, gender norms governing women’s roles and power in agrifood systems are changing in response to climate change and other forces, with implications for how women respond to future climate shocks. Third, paying attention to local realities is important – behaviours do not necessarily substantiate local norms. Fourth, women experience strong support from other women in savings groups, religious organisations, reciprocal labour, and others. Fifth, critical moments, such as climate disasters, offer potentially pivotal moments of change which could permit women unusually high levels of agency to overcome restrictive gender norms without being negatively sanctioned. The article concludes with recommendations for further research.
