These include sea surface temperature increases, irregular precipitation patterns and reduction of glacier-covered areas. In addition, climate scenarios show amplification in rainfall variability related to the warmer conditions associated with El Niño events. Extreme weather can affect human health, increase shocks and stresses to the health systems, and cause large economic losses. In this article, we study the characteristics of El Niño events in Peru, its health and economic impacts and we discuss government preparedness for this kind of event, identify gaps in response, and provide evidence to inform adequate planning for future events and mitigating impacts on highly vulnerable regions and populations. This is the first case study to review the impact of a Coastal El Niño event on Peru’s economy, public health, and governance. The 2017 event was the third...

Yet few studies have examined the “double burden of malnutrition” (DBM) over time in indigenous communities. We investigated changes in the food systems and nutritional health of Awajún communities in the Peruvian Amazon in the 1970s and in 2013. Methods included ethnography, 24 hr food recalls, and biological measures. In 2013, the number of traditional foods consumed decreased to 10% of levels in the 1970s and the number of market foods consumed increased 40-fold. Rates of anemia and obesity were also substantially higher in 2013 compared to the 1970s (23% vs 6% for anemia and 30% vs. 0% for obesity) indicating a DBM has emerged. Examining the predictors of hemoglobin levels and body mass indices in the 2013 sample reveals that this DBM is differentially impacting women and that risk for obesity among the Awajún is associated with multiple proxies of market integration beyond just the consumption of market foods. These findings highlight the complex pathways by which rapid lifestyle changes are creating gendered health inequalities within indigenous communities over time.

Nonetheless, this is a complex concept, which can be operationalized in different ways and has no specific standardized measures. This research explores Peruvian scallop aquaculture in the Sechura Bay of Peru as a case study, focusing on the development of social capital among fishers, enterprises and authorities. We evaluated social capital through three of its conceptual building components: (i) trust, (ii) collaboration and reciprocity, and (iii) common norms and sanctions. Specific indicators for each component were developed for analytical purposes. We conducted 66 surveys and 12 interviews with fishers and other key stakeholders. Based on our results, there is weak social capital among aquaculture fishers, enterprises and authorities in the Sechura Bay. This is evident through the low levels of trust and collaboration, as well as the lack of respect for common norms. Weak social capital may explain the two critical problems the system is currently facing for achieving sustainability: reduced availability of seeds and unfair agreements between enterprises and fishermen associations. Strengthening social ties and collaboration can increase aquaculture's resilience at Sechura Bay.
