abstract = {The term agroecology has undergone broad diversification since it was first conceived as the study of the ecology of agricultural systems. In addition to the “tripartite” definition, which includes science, practice, and social movement, political and “emancipatory” agroecologies, among others, are included. There is no consensus on the meaning of “agroecology” and “agroecological,” nor the objectives and uses associated with those concepts. Thus, despite the concept of “agroecology” not being consolidated nor unisemic, its meaning and application continue to diversify according to the interests and perspectives of the users. That diversification encompasses different ways of looking at agriculture’s role in human societies and the environment in which they are based and function. Agroecology, too, has been seen as an activity whose objectives include issues as diverse as mythical, ceremonial, dogmatic, political, or religious. Moreover, this unrestricted diversification also devalues and trivializes the term and hinders the mutual understanding among academics, practitioners, promoters, decision-makers, the public, and government agencies. We begin a series of reflections on the various agroecologies in Mexico that we hope will promote the formation of clear, well-defined, and documented concepts to contribute to synergies among agroecologies and the advancement of their objectives.},

abstract = {Maize is one of the most important crops in the world, particularly in Mexico where it was domesticated and is central to traditional cultures. The fall armyworm (Spodoptera frugiperda [J.E. Smith]), is a major pest that can greatly reduce production of this crop. Climate change also threatens maize production, as projections estimate an increase of fall armyworm outbreaks. For these reasons, (1) we assessed the changes in the S. frugiperda life cycle along a temperature gradient ranging from 23 °C to 31 °C, and (2) assessed the development of larvae feeding on two Mexican landraces and the responses of each landrace to herbivory under current and predicted climatic conditions; both assessments were conducted under laboratory conditions. Development was faster and each life cycle stage was shorter at higher temperatures. The effect of herbivory differed between the landraces; herbivory was more harmful for White Ranchero than for Yellow. As warmer and drier conditions are expected during this century, sowing appropriate maize landraces that can cope with herbivores under climate change could mitigate potential economic losses.},

abstract = {Human impact on the planet is such that geologists have acknowledged the start of a new geological epoch, the Anthropocene, which is characterized by an environmental emergency with multiple open fronts such as climate change, biodiversity loss, decreased fresh water availability, alterations to the nitrogen cycle, and chemical pollution. Activities such as food production and the increasing aggregation of people in urban areas are simultaneously major drivers and vulnerable points of such environmental change. For example, climate change represents a major threat to food production, considering that a reduction of annual precipitation, in addition to temperature increases, is likely to occur especially in tropical agricultural regions. The use of CAM crops has been recognized as a useful strategy for climate change adaptation, owing to their tolerance of high temperatures and their inherently high water use efficiency. The potential performance of Opuntia ficus-indica and Agave tequilana is modeled as an application of the Environmental Productivity Index for identifying potential areas for cultivation under climate change. Regarding alterations to the nitrogen biogeochemical cycle, CAM epiphytes can be useful to characterize environmental pollution in tropical environments, especially when electrochemical monitoring networks are lacking. Indeed, CAM epiphytes are particularly promising to characterize the prevalent levels of heavy metals, persistent organic pollutants and, especially, nitrogen deposition. This is illustrated with the use of the orchid Laelia speciosa and the bromeliad Tillandsia recurvata as biomonitors of atmospheric nitrogen deposition. From fundamental research on the mechanisms behind plant responses to environmental change to applications in agriculture and biomonitoring, CAM ecophysiology will be essential in the Anthropocene.},

abstract = {Phosphorus is an essential element for agricultural production, and for life in general, whose availability as a mineral is geographically restricted. Considering that Mexico is a major contributor to the global flow of water embedded in agricultural commodities, it is likely that this country is also a major exporter of embedded phosphorus. Thus, we quantified the embedded phosphorus for the 38 major crops produced in Mexico from 1980 to 2015, which were grouped into forages, fruits and vegetables, cereals, legumes, and cash crops. The total phosphorus extracted was 4.4 × 106 tonnes for an agricultural production of 5,844 × 106 tonnes, which respectively increased by 86% and 145% over 35 years. Food crops, i.e., cereals, fruits and vegetables, and legumes, accounted for 44% of the total phosphorus extracted, forages for 38%, and cash crops for 18%. Forage production exhibited a substantial increase since 1995, becoming the largest phosphorus extractor by 2000. Our estimation of embedded phosphorus is susceptible of utilization in other countries and is a first step to estimate a country's phosphorus balance, which is necessary to understand the magnitude of the anthropogenic alteration of a biogeochemical cycle that is essential for the maintenance of life on earth.},

Esta obra era necesaria y urgente en una época en la que son evidentes los efectos nocivos de las acciones humanas sobre el medio ambiente. Nuestro impacto ha sido
tal, que los científicos ya hablan de una nueva épocageológica, el Antropoceno, cuyo inicio se remonta a la mitaddel siglo 20 y se puede fechar tanto por los rastros de la detonación de bombas nucleares, como por los restos óseos de incontables pollos que yacen en los basureros de todo el planeta.
El conflicto entre la humanidad y la naturaleza surge de nuestra certeza de ser ajenos a ella. Pero eso es una percepción errónea. Los humanos somos parte integral de la naturaleza: de ella surgimos, con ella seguimos evolucionando y gracias a ella y a su biodiversidad, ha sido posible la existencia misma de nuestras diversas civilizaciones y culturas.
Una vía para restablecer el vínculo perdido con la naturaleza es la comida. Después de todo, la comida también es biodiversidad, desde el maíz de las tortillas y las verduras del caldo, hasta la carne asada del fin de semana. Además, todas las personas comemos tres veces al día, o deberíamos poder hacerlo.
Es así que, a través de distintas ensaladas, sopas, platos fuertes y postre, presentamos estas reflexiones sobre el estado del planeta. Y es que al considerar el origen, el uso y la sostenibilidad de ingredientes tan diversos como el nopal y las bellotas silvestres, pasando por verdolagas, zanahorias, papas, chapulines y otros artrópodos (considerados por muchos como el futuro de la alimentación humana), hasta el camarón, el pollo y la res, traemos a la mesa temas tan urgentes como el cambio de uso de suelo y el calentamiento global, ese que tiene al planeta «como agua para chocolate», pero no en el sentido recreativo.
Esperamos convencer a los lectores de que replanteando nuestra relación con la comida, podemos contribuir a mejorar al mundo y avanzar hacia un estado en el que la humanidad y la naturaleza vuelvan a ser indistinguibles.

abstract = {On his first day in office, on 1 December 2018, freshman President of Mexico, Andrés Manuel López Obrador (AMLO) delivered a speech outlining 100 policy priorities of his administration. The present study analyzed the contributions of this government’s program relating to food security and their environmental implications, and whether they contributed to strengthen the state or improved human security, considering that the poor and marginalized were at the center of AMLO's campaign. In total 45 policy priorities were geared to consolidate the state, while 55 contributed to improving human security. Only six were related to food security, including stipends to food producers and purchasing grains at guaranteed prices, a fertilizer distribution program and subsidies for cattle husbandry and fisheries/aquaculture. These programs contributed to advancing 10 of the 17 Sustainable Development Goals, especially those related to Zero Hunger and Reduced Inequalities. Various policy programs had explicit considerations towards climate change and land degradation, including the exclusion of natural protected areas from agricultural subsidies, and recognized that food production is vulnerable to climate change. The four agricultural programs analyzed may advance AMLO’s goal of avoiding food imports, while curbing rural poverty. However, available evidence is mixed regarding animal acquisition loans, which are likely to have adverse environmental outcomes. Finally, the program for developing agroforestry operations is already contributing to deforestation, and further ecosystem degradation is most likely to occur from the introduction of timber and fruit species to natural forests as this program does not preclude the inclusion of recently cleared plots. If human development goals are to be reached, along with fulfilling the international commitments on sustainable development and environmental conservation, policies need to be implemented that simultaneously tend to a booming transnational industry, while bringing forward the rural poor, who amount to nearly half of the country's population.

abstract = {The temperature and water potential requirements for seed germination were determined for five heirloom maizes from three different agroclimatological regions from the P'urhépecha community of San Francisco Pichátaro, Michoacán, Mexico. Germination experiments were conducted in environmental controlled chambers exposing seeds to day/night air temperatures (12 h photoperiod) of 15/5, 20/10, or 35/25ºC, and to water potentials of 0, –0.01, –0.05, –0.1, or –0.5 MPa, which were created with aqueous solutions of polyethylene glycol (molecular weight 20,000). Germination was maximal and occurred at a faster rate for seeds incubated at 35/25ºC. In turn, a high water potential of 0.0 or –0.01 MPa was necessary to achieve maximum germination, which decreased under more negative water potentials until germination was completely inhibited for seeds incubated under –0.5 MPa failed. Although an environmental specialization for germination was not observed among the heirloom maize evaluated, their ability to germinate maximally under high temperatures is indicative of their cultivation potential under the increasing air temperatures expected to occur during the present century. In contrast, germination sensitivity to relatively mild water potentials may be a conservative ecophysiological trait of drought-escape for this tropical annual plant.},

The most marginalized states had the highest number of landraces, 80% of which were found in predominantly or substantially indigenous municipalities. While only one third of 152 regions of high biodiversity had collection records, 47 landraces had at least one collection record in these regions. Eleven races can be cultivated in at least 10% of the Mexican territory, while 13 can occupy less than 1% under current environmental conditions. Given a projected temperature increase of 0.5 oC and a 5% reduction in annual precipitation, 66% of the landraces could disappear during the current decade. A normalized Vulnerability Index was constructed (can have values from 0.00 for non-threatened landraces to 1.00 for the most vulnerable) that averaged 0.76 ± 0.02 for the 59 landraces. The most vulnerable third of the landraces were threatened by being from a region of low marginalization combined with a limited potential distribution both under current conditions and under the climate change scenario considered.},
