Climate Change Impacts, Adaptive Resilience, and Regenerative Livestock Adoption: A Resilience Trap in High-Andean Camelid Agroecosystems
(MDPI, 2026-08-28) Larios-Francia, Rosa Patricia; Cárdenas Minaya, Oscar Efraín; Condori Ticona, Andrés
Andean livestock agroecosystems depend on grassland and soil functionality to sustain productivity, threatened by climate-driven glacial retreat, pasture degradation, and increasingly frequent frosts, hailstorms, and droughts. Grounded in the Resilience Thinking framework for socio-ecological systems, this study proposes and validates an explanatory model examining how perceived climate change impacts (IMP) drive the adoption of regenerative livestock farming (ADOP) and impact the deterioration of livestock performance (DES), with adaptive capacity and resilience (RES) as a mediating construct. Regenerative livestock farming is operationalized through soil, forage, water, and biodiversity management, animal welfare, and climate adaptation strategies. Survey data from 91 South American camelid producers in the Puno region, Peru, were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with second-order constructs. Climate impacts emerge as the strongest antecedent of adaptive resilience (β = 0.718) and regenerative adoption (β = 0.604) and have a significant direct effect on performance deterioration (β = 0.292; p = 0.041). However, resilience does not significantly predict adoption (β = 0.075; p = 0.619), revealing institutional, technological, and knowledge-related barriers that disconnect adaptive capacity from ecological transformation. Both adoption (β = 0.327; p = 0.002) and resilience (β = 0.335; p = 0.003) are positively associated with performance deterioration, suggesting reactive containment rather than consolidated restoration. Findings indicate adaptive rather than transformative resilience in high-Andean livestock systems, indicating that an effective regenerative transition requires participatory, context-sensitive approaches supported by policies and technical assistance that strengthen long-term productive sustainability and food security in vulnerable communities.
I'll be dammed: Efficiency and cost-analysis of a rehabilitated prehispanic dam in the Andes
(Wiley, 2026-07-08) Lane, Kevin; Flores Marquez, Ricardo; Puga Calderón, Rodrigo Julio; Gonzales, Pedro; Advíncula, Mario; Herrera, Alexander
Within archaeology there is a growing shift away from the purely aesthetic towards making the past relevant to present and future needs and demands. The Past Water Futures project charts the impact of ancient dam rehabilitation on climate change‐induced water scarcity in the North Central Andes. The rehabilitation of late period (AD 750–1532) Prehispanic dams is a novel approach to assuage increasing water shortage among the rural communities of the Andean highlands. Nevertheless, until now, we lacked data on the real‐time impact of these modern conservation and rehabilitation projects. Here we present preliminary results, including volume capacity, potential demand, hydrological and hydraulic analysis and a reservoir filling log of the Prehispanic Weetacocha ‘Lake of Flowers’ Dam, which was rehabilitated in late 2024. Weetacocha belongs to the rural community of Racratumanka, District of Pamparomás, Province of Huaylas, Ancash Region, Peru. Importantly, we analyse the cost per m3 unit of water recovered through the rehabilitation of the Weetacocha Dam, proving that the restoration of water dams can provide a viable, cost‐effective, community‐led, sustainable alternative to modern micro‐dam construction in the Central Andes and potentially further afield.
