Toward a feminist political ecology of household food and water security during drought in northern Nicaragua النص الكامل

Few studies assess the relationship between food and water access, despite global concerns about people's inability to maintain access to both food and water. We conducted a mixed-methods comparative case study in northern Nicaragua, with smallholders from two neighboring communities that differed in water availability and institutional strength, using a feminist political ecology framework and food and water security definitions that focus on access, availability, use, and stability. We adopted a participatory approach that included: a sex-disaggregated survey in 2016; interviews, participant observation, and community-based water quality testing from 2014 to 2019; and analysis of a severe drought that occurred from 2014 to 2017. Our results suggest that uneven power relations, biophysical conditions, gender, and institutions shape food and water access, and indicate that households across both communities average 2 months of drinking water insecurity during the dry season followed by an average of 2.5 months of food insecurity early in the growing season. The average duration of lean food months was similar across communities and sex, but water insecurity lasted longer in the community that had weaker local institutions and less surface water availability. Ethnographic research helped to document uneven and gendered experiences of water access and to illustrate how they were also shaped by conflicts over water for irrigation vs. domestic uses and cross-scalar limitations in water and land governance. Although we found that gender and institutions were not strong predictors of several food and water insecurity indicators on their own, both factors influenced the terms of access, conflict, and cooperative governance needed to secure resources and well-being. Our study highlights the need for theory, methods, and field research that integrate the analysis of food and water security, and it contributes to developing a feminist political ecology approach that unifies this analysis with a focus on gender.

World hunger, according to the 2012 Global Hunger Index (GHI), has declined somewhat since 1990 but remains “serious.” The global average masks dramatic differences among regions and countries. Regionally, the highest GHI scores are in South Asia and Sub-Saharan Africa. South Asia reduced its GHI score significantly between 1990 and 1996—mainly by reducing the share of underweight children— but could not maintain this rapid progress. Though Sub-Saharan Africa made less progress than South Asia in the 1990s, it has caught up since the turn of the millennium, with its 2012 GHI score falling below that of South Asia. From the 1990 GHI to the 2012 GHI, 15 countries reduced their scores by 50 percent or more. In terms of absolute progress, between the 1990 GHI and the 2012 GHI, Angola, Bangladesh, Ethiopia, Malawi, Nicaragua, Niger, and Vietnam saw the largest improvements in their scores. Twenty countries still have levels of hunger that are “extremely alarming” or “alarming.” Most of the countries with alarming GHI scores are in Sub-Saharan Africa and South Asia (the 2012 GHI does not, however, reflect the recent crisis in the Horn of Africa, which intensified in 2011, or the uncertain food situation in the Sahel). Two of the three countries with extremely alarming 2012 GHI scores—Burundi and Eritrea—are in Sub-Saharan Africa; the third country with an extremely alarming score is Haiti. Its GHI score fell by about one quarter from 1990 to 2001, but most of this improvement was reversed in subsequent years. The devastating January 2010 earthquake, although not yet fully captured by the 2012 GHI because of insufficient availability of recent data, pushed Haiti back into the category of “extremely alarming.” In contrast to recent years, the Democratic Republic of Congo is not listed as “extremely alarming,” because insufficient data are available to calculate the country’s GHI score. Current and reliable data are urgently needed to appraise the situation in the country. | Non-PR | IFPRI2; GRP24 | COM; MTID; DGO; EPTD; PHND; WCAO
اظهر المزيد [+] اقل [-]Cadmium pollution of water, soil, and food: a review of the current conditions and future research considerations in Latin America النص الكامل
2022
Alves Peixoto, Rafaella Regina | Jadán-Piedra, Carlos
The presence of cadmium (Cd) in food produced in Latin America has been highlighted in recent years. Cadmium can be toxic to humans at low levels, and therefore monitoring its presence in food is relevant for public health. Cadmium concentrations from different sources, such as water, soil, sediment, food, and beverages were examined and discussed to address the non-occupational exposure of the Latin American population to Cd. A literature review was conducted examining publications from 2015 to 2020 and data available in the ScienceDirect and PubMed databases. Twenty-eight papers reported on Cd in water, 49 reported Cd in soil and sediments, and 86 reported on Cd in food. We have identified and discussed the factors affecting the environmental behavior and bioaccumulation of Cd, the main species used in monitoring studies, and the necessity for future research. Brazil and Mexico are the countries that provided the most available information, whereas for some countries in Central America, no information was found. The Cd levels in food examined in these studies (mostly fish and cacao) were generally below the established maximum levels, indicating a low risk. When considering the presence of Cd in food, water, and soil, Cd fractionation and chemical speciation studies are fundamental to understanding which forms of Cd are the most toxic. In turn, studies on bioaccessibility and bioavailability of Cd in food are also needed for more adequate risk assessment, but they are currently scarce within Latin America.

De acuerdo con el Índice Global del Hambre (GHI, por sus siglas en inglés) de 2012, el hambre a nivel mundial ha disminuido algo desde 1990 pero continúa siendo “serio”. El promedio global enmascara diferencias dramáticas entre regiones y países. A nivel regional, los mayores puntajes del GHI se encuentran en Asia meridional y en el África Subsahariana. Asia meridional redujo sus puntajes de GHI de forma significativa entre 1990 y 1996 —principalmente a través de una reducción en la proporción de niños con bajo peso— pero no pudo mantener este rápido progreso. Y aunque el África Subsahariana progresó menos que Asia meridional en la década de 1990, ha logrado reducir la brecha a partir del nuevo milenio, con un puntaje del GHI en 2012 apenas por debajo del obtenido por Asia meridional. | Non-PR | IFPRI2; GRP24 | COM; MTID; DGO; EPTD; PHND; WCAO
