California’s Central Valley is arguably the most productive agricultural region in the world. Despite making up only 1% of all farmland in the United States, it produces 250 different crops that make up a quarter of all food consumed in the U.S., including close to half of all fruit, nuts, and table foods. The map included below shows the variety and intensity of this kind of cultivation. This level of agricultural production has been made possible by the dominance of industrial agriculture interests at all levels of government, resulting in one of the most physically altered landscapes in the world. These alterations focused in large part on water, the biggest limiting factor for industrial agriculture in a region technically classified as a desert. Over the course of the 20th century, the largest body of freshwater west of the Mississippi–Tulare Lake–was drained to make more land available, the Central Valley Project and State Water Project built thousands of miles of canals and tens of dams to control the supply of water for irrigation, and massive groundwater aquifers were pumped nearly dry during drought years. These transformations were accomplished through the utilization of rhetoric that emphasizes the centrality of the farmer identity to the American political imaginary (despite the massive distance between Californian industrial agriculture and the Jeffersonian agrarian ideal) and the unique importance of providing the nation’s food. This kind of exceptionalism has characterized agriculture across the United States since its inception and has repeatedly produced other forms of social injustice (e.g., the exclusion of agricultural laborers from U.S. labor protections) that compound the hazardous effects of its environmental injustices.

Studie provides visual representations of lead concentration in Santa Ana cross matching it with vulnerability risk.

“Also of note when interpreting our results is that this study did not take into consideration the ingestion of heavy metals through the dietary route. Had we considered this additional exposure pathway, our calculated chronic daily intake levels of heavy metals would have been greater, resulting in higher estimated risk (particularly for metals such as Pb, As, and Cd which have been widely documented in various foods)” (Marsi et al. 2021)

“Both cancer and non-cancer risk at the Census tract level exhibited positive correlations with indicators of social as well as physiological vulnerability” (Marsi et al. 2021)

Exposure to heavy metals has been associated with adverse health effects and disproportionately impacts communities of a lower socio-economic status.  

This study used a community-based participatory research approach to collect and analyze a large number of randomly sampled soil measurements to yield a high spatially resolved understanding of the distribution of heavy metals in the Santa Ana soil, in an effort to exposure misclassification. This study looks into average metal  concentrations at the Census tract level and by land use type, which helps map potential sources of heavy metals in the soil and better understand the association between socioeconomic status and soil contamination (Marsi et al. 2021). 

In 2018, soil samples of eight heavy metals including lead (Pb), arsenic (As), manganese (Mn), chromium (Cr), nickel (Ni), copper (Cu), cadmium (Cd), and zinc (Zn) were collected across Santa Ana. These were analyzed at a high resolution using XRF analysis. Then, metal concentrations were mapped out and American Community Survey data was used to assess the metals throughout Census tracts in terms of social and economic variables. Risk assessment was conducted to evaluate carcinogenic risk. The results of the concentrations of soil metals were categorized according to land-use type and socioeconomic factors. “Census tracts where the median household income was under $50 000 had 90%, 92.9%, 56.6%, and 54.3% higher Pb, Zn, Cd, and As concentrations compared to high-income counterparts” (Marsi et al. 2021). All Census tracts in Santa were above hazard inder >1, which implies non-carcinogenic effects, and almost all Census tracts showed a cancer risk above 104, which implies greater than acceptable risk. Risk was found to be driven by childhood exposure.

It was concluded that the issue of elevated soil contamination relates back to environmental justice due to overlap between contaminated areas and neighborhoods of lower socioeconomic status. Marsi et al. (2021) found there needs to be more community-driven recommendations for policies and other actions to address disproportionate solid contamination and prevent adverse health outcomes.

The educational program in Haiti organized by Handicap International aims to train citizens of Haiti for careers as rehabilitation technicians and orthopedic technicians. The program is designed to provide a recognized degree allowing graduates to work as technicians under the supervision of physical therapists and orthopedic doctors. 

Handicap International brings aid to places dealing with the aftermath of natural disasters. In this case the Rehabilitiation Technicians pogram was created in response to the 2010 earthquake in Haiti, during which thousands of Hatians needed orthopedic rehabilitation or prosthetics and there was a significant shortange of specialized medical professionals. The program was created to respond to the need for rehabilitation professionals to deal with the immediate aftermath of the earthquake and the continuing care of those permanently disabled.

This program is one of many run by Handicap International, and supported by the United States Agency for International Development. The program was run at Healing Hands for Haiti (http://www.haitilibre.com/en/news-14990-haiti-health-first-in-haiti-tra…), with instructors from the Universidad de Don Bosco in El Salvador.
