MARISOL ALCOCER PERULERO (2021, [Capítulo de libro])
Este livro analisa as raízes histórico-coloniais do racismo no Brasil, na Bolívia, na Colômbia e no México, aprofundando em suas origens desde a colonização, a escravização de indígenas e africanos durante séculos, a biopolítica de extermínio, submissão, superexploração e negação de suas identidades e culturas; a reprodução da biopolítica de eliminação desses povos até os dias atuais com a renovação de conceitos e discursos eugenistas e discriminatórios, de sua repetição cotidiana em diferentes espaços privados e públicos, nas instituições, nas comunidades, nas famílias, nas relações sociais, no Estado, legitimando e aprofundando as desigualdades estruturais baseadas nos preconceitos de gênero, geracionais, étnico-raciais e de classe social.

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.

This study determined the most effective plating density (PD) and nitrogen (N) fertilizer rate for well-adapted BH540 medium-maturing maize cultivars for current climate condition in north west Ethiopia midlands. The Decision Support System for Agrotechnology Transfer (DSSAT)-Crop Environment Resource Synthesis (CERES)-Maize model has been utilized to determine the appropriate PD and N-fertilizer rate. An experimental study of PD (55,555, 62500, and 76,900 plants ha−1) and N (138, 207, and 276 kg N ha−1) levels was conducted for 3 years at 4 distinct sites. The DSSAT-CERES-Maize model was calibrated using climate data from 1987 to 2018, physicochemical soil profiling data (wilting point, field capacity, saturation, saturated hydraulic conductivity, root growth factor, bulk density, soil texture, organic carbon, total nitrogen; and soil pH), and agronomic management data from the experiment. After calibration, the DSSAT-CERES-Maize model was able to simulate the phenology and growth parameters of maize in the evaluation data set. The results from analysis of variance revealed that the maximum observed and simulated grain yield, biomass, and leaf area index were recorded from 276 kg N ha−1 and 76,900 plants ha−1 for the BH540 maize variety under the current climate condition. The application of 76,900 plants ha−1 combined with 276 kg N ha−1 significantly increased observed and simulated yield by 25% and 15%, respectively, compared with recommendation. Finally, future research on different N and PD levels in various agroecological zones with different varieties of mature maize types could be conducted for the current and future climate periods.

Addressing agricultural labour issues is key to biodiversity-smart farming
Thomas Daum Frédéric Baudron Matin Qaim Ingo Grass (2023, [Artículo])
There is an urgent need for agricultural development strategies that reconcile agricultural production and biodiversity conservation. This is especially true in the Global South where population growth is rapid and much of the world's remaining biodiversity is located. Combining conceptual thoughts with empirical insights from case studies in Indonesia and Ethiopia, we argue that such strategies will have to pay more attention to agricultural labour dynamics. Farmers have a strong motivation to reduce the heavy toil associated with farming by adopting technologies that save labour but can negatively affect biodiversity. Labour constraints can also prevent farmers from adopting technologies that improve biodiversity but increase labour intensity. Without explicitly accounting for labour issues, conservation efforts can hardly be successful. We hence highlight the need for biodiversity-smart agriculture, that is farming practices or systems that reconcile biodiversity with land and labour productivity. Our empirical insights suggest that technological and institutional options to reconcile farmers' socio-economic goals and biodiversity conservation exist but that more needs to be done to implement such options at scale.

Local markets and food security. The case of the Milpera and Puuc regions in Yucatan
Ana Laura Bojórquez Carrillo Monserrat Vargas Jiménez Mireya Noemi Hernández Islas (2023, [Artículo, Artículo])
Food insecurity is a complex problem worldwide. A major part of this problem is the food supply. Local markets can represent a strategy for building social capital, as well as strategies for subsistence and sustainability of food value chains, contributing to food security and its effects. The objective of this research is to determine if the existence of a municipal market in the Milpera and Puuc regions of Yucatán favors the existence of food security, the consumption or the expense of natural foods. The population is located in 18 municipalities of Yucatán, Mexico. To carry out this study, a cross-sectional, non-experimental study, with a quantitative approach and correlational scope. The main techniques that were applied were descriptive statistics and contingency tables with respect to 6 hypotheses. This work shows that the existence of markets in the communities makes a significant difference because it positively impacts the food security of the inhabitants, since it allows them to have access to a wider variety of products and at the same time, favors the active dynamics of the economy of the community.

Impacto del cambio climático en el desarrollo y requerimientos hídricos de los cultivos
Climate change impact on crop development and water requirements
WALDO OJEDA BUSTAMANTE WALDO OJEDA BUSTAMANTE MAURO IÑIGUEZ COVARRUBIAS MARTIN JOSE MONTERO MARTINEZ (2010, [Artículo])
Debido al impacto del cambio climático la modificación de los componentes del ciclo hidrológico, principalmente la evapotranspiración y la precipitación, tendrá un efecto radical en las demandas de riego y en la gestión de los sistemas de riego. Las proyecciones del cambio climático indican un
incremento de la temperatura ambiental, con variabilidad en el espacio y en el tiempo. En este trabajo se analizó el impacto esperado del cambio climático en las demandas hídricas y en el desarrollo de los cultivos usando proyecciones de cambio climático para el escenario de emisiones medio moderado (A1B), para las condiciones del Distrito de Riego 075, Río Fuerte, Sinaloa, México.
Due to the impact of climate change, the modification of water cycle processes, mainly evapotranspiration and precipitation, will have a radical effect on irrigation water demands and management of irrigation systems. Climate change projections indicate an increase in air temperature, with spatial and temporal variability. In this study, we analyzed the expected impact of climate change on water demands and crop development, by using climate change projections for the moderate-medium emissions scenario (A1B), for the conditions of Irrigation District 075, Río Fuerte, Sinaloa, México.
