Cheyenne River Sioux Traditions and Resistance to the Dakota Access Pipeline

The No Dakota Access Pipeline resistance movement provides a poignant example of the way in which cultural, spiritual, and oral traditions remain authoritative in the lives of American Indian peoples, specifically the Lakota people. Confronted with restrictions of their religious freedoms and of access to clean drinking water due to construction of the Dakota Access Pipeline (DAPL), members of Lakota communities engaged with traditions specific to their communities to inform and structure the No DAPL resistance movement. A series of interviews conducted on the Cheyenne River Sioux Nation with tribal members reveal that Lakota spiritual traditions have been integral to every aspect of the movement, including the motivations for, organization of, and understanding of the future of the movement.

The Women of the Cheyenne River Sioux Tribe Reservation

This chapter describes the impact of colonialism on indigenous women with a focus on the experience of the Lakota women on the Cheyenne River Sioux Tribe Reservation in South Dakota. It explores the experiences of indigenous women as related to history, culture, intrapersonal violence, and internalized oppression. A case study of a Lakota woman is provided as an example of strength and triumph in overcoming adversity and being empowered despite the challenges of marginalization faced by many Native Americans in the United States and indigenous women throughout the world. The chapter discusses how readers can be advocates and actively engage in decolonizing and dismantling systems of oppression to protect future generations and to allow indigenous communities to heal and revitalize.

Active smoking, secondhand smoke exposure and serum cotinine levels among Cheyenne River Sioux communities in context of a Tribal Public Health Policy

IntroductionAmerican Indians and Alaska Natives face disproportionately high rates of smoking and secondhand smoke (SHS) exposure. The Cheyenne River Sioux Tribe (CRST) is among the few Tribal Nations controlling commercial tobacco exposures in public and work places. We had an opportunity to explore effects of the new commercial tobacco-free policy (implemented in 2015) in an environmental health study (2014–2016) that collected information about commercial tobacco use and SHS prevalence and examined predictor variables of serum cotinine concentrations.MethodsSelf-reported survey data were used in quantile regression statistical modelling to explore changes in cotinine levels, based on smoking status, smokeless tobacco consumption and SHS exposure.ResultsFrom enrolled 225 adults, 51% (N=114) were current smokers. Among 88 non-tobacco users, 35 (40%) reported current SHS exposure. Significant differences in cotinine median concentrations were found among participants with and without current SHS exposure. Extremely high cotinine concentrations (~100 times larger than the median) were detected in some non-tobacco users. After implementing the new smoke-free air Tribal policy, cotinine decreased in participants with intermediate (3–15 ng/mL, non-tobacco users with SHS exposure) and high (>15 ng/mL, mainly tobacco users) cotinine levels showing association with an abatement of opportunities for SHS exposure. Significant predictors of cotinine levels were sampling year, current smoking and tobacco chewing. No gender differences were observed in cotinine.ConclusionsOur results show decrease in cotinine concentrations in CRST participants since implementation of their ‘Smoke-Free Clean Air Act’ in 2015.

Effect of bicarbonate and phosphate on arsenic release from mining-impacted sediments in the Cheyenne River watershed, South Dakota, USA

We investigated the effect of competing environmentally relevant anions (PO43−,HCO3−) on the release of As from solids (WW, DR) collected from the Cheyenne River watershed exposed to surface oxidizing conditions.
