Urban Andes

Climate change in the Andes is affecting the relation between urban development and the landscape. Design-led explorations are reframing landscape logics and urbanisation patterns within the Cachi River Basin of Ayacucho, Peru. A co-production of students, researchers and designers, the book suggests alternative futures, crossing scales of landscape systems to new settlement typologies. Urban Andes marks the start of the new series LAP on innovative design research in architecture, urbanism, and landscape. It is the result of a two-year collaboration (2018–2020), initiated by the CCA in cooperation with KU Leuven and various partners, including local organisations and the VLIR-UOS.

New altitudinal records of Panthera onca (Carnivora: Felidae) in the Andean region of Ecuador

We report two records of jaguars (Panthera onca) registered with camera traps at 2300 and 2660 m a.s.l. in the Ecuadorian Andes, which represent the first verifiable records of the species above 2000 m in Ecuador. As the first records of jaguars from Río Negro-Sopladora National Park and Tapichalaca Reserve, these records raise important questions about the species’ ecology and conservation in Andean montane forests. From a regional perspective, these records may indicate connectivity between jaguar populations inhabiting both sides of the Andes. Sustained monitoring of wildlife populations is necessary to discern the significance of these records and help develop strategies to ensure the conservation of this highly mobile species across the increasingly fragmented Andean-Amazonian landscapes of southern Ecuador.

The complete genome sequences of Erythroxylum coca and Erythroxylum novogranatense

The flowering plant genus Erythroxylum contains approximately 300 species, including the economically and socially consequential crops called coca. We present the genome sequences of Erythroxylum coca and E. novogranatense, two cultigens produced for medicinal and quotidian use in the Andes and Amazon regions of South America, as well as the international cocaine industry. Sequencing was performed on an Illumina X-Ten platform, and reads were assembled by a de novo method followed by finishing via comparison with several species from the same genus. The BioProject, raw and assembled data can be accessed in GenBank for E. coca (PRJNA676123; JAJMLV000000000) and E. novogranatense (PRJNA675212; JAJKBF000000000)

Hematological Parameters and Iron Status in Adult Men and Women Using Altitude Adjusted and Unadjusted Hemoglobin Values for Anemia Diagnosis in Cusco, Peru (3400 MASL)

(1) Background: Current diagnosis of anemia in high altitude populations uses an adjustment of observed hemoglobin (Hb) values. Such an approach has been challenged by findings in different populations in Tibet, Ethiopia and the Andes as inappropriate, as it might incorrectly classify an individual with complete iron stores as anemic. We aimed to assess the suitability of this approach in adult men and women from Cusco, Peru (3400 m); (2) Methods: Complete blood count and iron status biomarkers were measured in 345 subjects (189 females and 156 males), iron status biomarkers were quantified with enzyme-linked immunoassays; (3) Results: Anemia prevalence was overestimated when the altitude-adjustment factor was applied. Hematological parameters were better correlated to iron status biomarkers in the non-adjusted anemia category. When stratified by sex, only women showed a significant association between Hb and other hematological parameters with iron storage and availability (Hepcidin and TFR-F); (4) Conclusion: The prevalence of anemia is overestimated with current guidelines. The rate of anemia using non-adjusted Hb values is more closely related to the rates of anemia or iron deficiency when used hematological parameters, markers of iron status, and measurements of hepcidin and erythropoietin. Sex differences related to iron status were observed, suggesting that men are at a higher risk of iron overload than women at high altitudes. It could be highlighted that a personalized approach is important when assessing a subject, taking in to account hematological parameters as well as origin (Southern Andean or other).

Extinction in transition: coca, coal, and the production of enmity in Colombia's post-peace accords environment

At the Paris Climate Summit in 2015, then Colombian president Juan Manuel Santos proposed constructing a multi-national biodiversity corridor that would extend from the Andes to the Brazilian Atlantic coast. Santos highlighted increased militarization of the territory as one advantage of the corridor. In this model, ecological conservation becomes a matter of national/natural security, in the form of counterinsurgency to counter illegal economies. Climate change and ecological disaster mean the forest needs the military power of the State to save it from destruction. We argue that such conservation entails a form of necropolitics lying in wait; because to conserve one part is to condemn the other – framed as the enemy – to certain destruction, as land is simultaneously designated for large-scale development projects. Conservation, in effect, becomes tied to a form of extinction. Our article examines two increasingly militarized frontiers that work through conservation in Colombia. The first is where the Andes meets the Amazon rainforest, an area that has seen an increase in deforestation following the 2016 Peace Agreement with the FARC. Deforestation is often attributed to the cultivation of coca (used to produce cocaine), and the solution posited by the government is to eradicate the plant. We argue that eradication of illicit crops is a form of enforced extinction that militarizes the forest, targeting both human and non-human inhabitants. The second frontier concerns coal mining on the Caribbean coast, where mass environmental devastation induced by the industry has led to a forced reorganization of life in the region. The military guards the sites of extraction and those who oppose coal mining become targets for elimination. We bring these two cases – coal and coca – into dialogue, to trace the extinction-driven expansion of extractive economies, a process intertwined with armed conflict, narcotrafficking, and now with transitional politics.
