Physical functionality of coral reefs in the mexican Pacific (Bahía de Los Ángeles, Bahía de La Paz, Bahía de Banderas y Bahías de Huatulco)

CLAUDIA REBECA NAVARRETE TORICES (2023, [Tesis de maestría])

Los corales son la base en la estructura y funcionamiento de los arrecifes. Sin embargo, en las últimas décadas, estos ecosistemas han sufrido un deterioro debido a presiones naturales, antrópicas y factores de gran escala como el cambio climático. En general, la cobertura de corales ha disminuido y aunque en algunos casos se ha observado su recuperación, la caracterización de la funcionalidad de la estructura física de los sistemas ha sido escasamente explorada. El presente trabajo evalúa la funcionalidad física de los arrecifes de coral en cuatro áreas a lo largo del Pacífico mexicano, empleando el Índice Funcional Arrecifal (IFA). El IFA considera la tasa de calcificación, la complejidad estructural y la abundancia de las especies de coral de en cada sitio; los valores que el índice puede adquirir varían de cero a uno, son valores cercanos a cero refieren a un arrecife con baja funcionalidad, mientras que los valores cercanos a uno indican un arrecife con alta funcionalidad. La cobertura coralina promedio de las cuatro áreas fue 35.62 ± 15.01%, siendo Bahías de Huatulco (BH) quien presentó la mayor cobertura coralina con 55.61 ± 21.94 %, mientras que Bahía de Los Ángeles (BLA) tuvo la menor cobertura coralina (17.16 ± 0.08 %). El IFA promedio de las áreas fue de 0.54 ± 0.12, y con base en el indicador, BH tuvo una mayor funcionalidad con un IFA de 0.68 ± 0.09, mientras que BLA tuvo una menor funcionalidad (0.34 ± 0.08). Los corales del género Pocillopora fueron los que mayor IFA aportaron en la mayoría de los sitios excepto en BLA que es representada por Porites panamensis. El coral con mayor coeficiente funcional (CF) fue Pocillopora grandis con 0.81, perteneciente a Bahía de Banderas (BB) y por ende fue el coral que mayor contribuyó al IFA en el área. El valor del IFA de 0.68 a lo largo del Pacífico mexicano, nos indica que tiene una alta complejidad estructural, debido a la forma de los corales Pocillopora que son clave para la permanencia de los arrecifes del área.

Corals are the basis for the structure and functioning of reefs. However, in recent decades, these ecosystems have suffered deterioration due to natural and anthropogenic pressures and large-scale factors such as climate change. In general, coral cover has decreased and although in some cases their recovery has been observed, the characterization of the functionality of the physical structure of the systems has been barely explored. This study evaluates the physical functionality of coral reefs in four areas along the Mexican Pacific, using the Reef Functional Index (IFA). The IFA considers the calcification rate, structural complexity, and abundance of coral species at each site; The values that the index can acquire vary from zero to one, values close to zero refer to a reef with low functionality, while values close to one indicate a reef with high functionality. The average coral cover of the four areas was 35.62 ± 15.01%, with Bahías de Huatulco (BH) having the highest coral cover with 55.61 ± 21.94%, while Bahía de Los Ángeles (BLA) had the lowest coral cover (17.16 ± 0.08%). The average IFA of the areas was 0.54 ± 0.12, and based on the indicator, BH had higher functionality with an IFA of 0.68 ± 0.09, while BLA had lower functionality (0.34 ± 0.08). Corals of the genus Pocillopora were the ones that contributed the highest IFA in most of the sites except in BLA, which is represented by Porites panamensis. The coral with the highest functional coefficient (CF) was Pocillopora grandis with 0.81, belonging to Bahía de Banderas (BB) and therefore was the coral that contributed the greatest to the IFA in the area. The IFA value of 0.68 along the Mexican Pacific indicates that it has a high structural complexity, due to the shape of the Pocillopora corals that are key to the permanence of the reefs in the area.

Can I speak to the manager? The gender dynamics of decision-making in Kenyan maize plots

Rachel Voss Zachary Gitonga Jason Donovan Mariana Garcia-Medina Pauline Muindi (2023, [Artículo])

Gender and social inclusion efforts in agricultural development are focused on making uptake of agricultural technologies more equitable. Yet research looking at how gender relations influence technology uptake often assumes that men and women within a household make farm management decisions as individuals. Relatively little is understood about the dynamics of agricultural decision-making within dual-adult households where individuals’ management choices are likely influenced by others in the household. This study used vignettes to examine decision-making related to maize plot management in 698 dual-adult households in rural Kenya. The results indicated a high degree of joint management of maize plots (55%), although some management decisions—notably those related to purchased inputs—were slightly more likely to be controlled by men, while other decisions—including those related to hiring of labor and maize end uses—were more likely to be made by women. The prevalence of joint decision-making underscores the importance of ensuring that both men’s and women’s priorities and needs are reflected in design and marketing of interventions to support maize production, including those related to seed systems, farmer capacity building, and input delivery.

Propaganda against Mexican women married to Chinese immigrants in Chihuahua 1920-1940

Vladimir Alejandro Armendáriz Romero Jesús Adolfo Trujillo Holguín (2023, [Artículo, Artículo])

At the turn of the 20th century and at the beginning of the new revolutionary government stage in Mexico, the press was an effective way to disseminate propaganda for the nationalist ideology of the State. An important part of this diffusion covered the question of the racial constitution of the mexicans, which led to the need to convince the public that it was important to determine controls over women and with whom they married since they were responsible for the reproduction of the Mexican race. Therefore, a mixture of races considered undesirable, such as the Chinese, was detestable. This propaganda occurred in the context of national anti-Chinese and anti-Jewish campaigns in which they wanted to expel these foreigners on the pretext that their presence and mixing with them would result in degeneration. In Chihuahua there are indications of this propaganda, but also that women married to Chinese resisted this campaign against their families.

Innovative approaches to integrating gender into conventional maize breeding: lessons from the Seed Production Technology for Africa project

Rachel Voss Jill Cairns Michael Olsen Esnath Tatenda Hamadziripi (2023, [Artículo])

The integration of gender concerns in crop breeding programs aims to improve the suitability and appeal of new varieties to both women and men, in response to concerns about unequal adoption of improved seed. However, few conventional breeding programs have sought to center social inclusion concerns. This community case study documents efforts to integrate gender into the maize-focused Seed Production Technology for Africa (SPTA) project using innovation history analysis drawing on project documents and the authors’ experiences. These efforts included deliberate exploration of potential gendered impacts of project technologies and innovations in the project’s approach to variety evaluation, culminating in the use of decentralized on-farm trials using the tricot approach. Through this case study, we illustrate the power of active and respectful collaborations between breeders and social scientists, spurred by donor mandates to address gender and social inclusion. Gender integration in this case was further facilitated by open-minded project leaders and allocation of funding for gender research. SPTA proved to be fertile ground for experimentation and interdisciplinary collaboration around gender and maize breeding, and has provided proof of concept for larger breeding projects seeking to integrate gender considerations.

Gender, rainfall endowment, and farmers’ heterogeneity in wheat trait preferences in Ethiopia

Hom Nath Gartaula Moti Jaleta (2024, [Artículo])

Wheat is a vital cereal crop for smallholders in Ethiopia. Despite over fifty years of research on wheat varietal development, consideration of gendered trait preferences in developing target product profiles for wheat breeding is limited. To address this gap, our study used sex-disaggregated survey data and historical rainfall trends from the major wheat-growing regions in Ethiopia. The findings indicated heterogeneity in trait preferences based on gender and rainfall endowment. Men respondents tended to prefer wheat traits with high straw yield and disease-resistance potential, while women showed a greater appreciation for wheat traits related to good taste and cooking quality. Farmers in high rainfall areas seemed to prioritize high straw yield and disease resistance traits, while those in low rainfall areas valued good adaptation traits more highly. Most of the correlation coefficients among the preferred traits were positive, indicating that farmers seek wheat varieties with traits that serve multiple purposes. Understanding men's and women's preferences and incorporating them in breeding and seed systems could contribute to the development of more targeted and effective wheat varieties that meet the diverse needs of men and women farmers in Ethiopia.
