Effectiveness of Billion Trees Tsunami Afforestation Projects in restoration of forests in Pakistan
The history of forest cover dynamics in Pakistan reveals an unsatisfactory environmental situation. In the past 5 decades, particularly during the period between 1990 and 2010, the country lost an average of 41,100 hectares of green cover with a deforestation rate of 1.6% per year. The factors behind that this high deforestation rate is numerous including socio-economic transformation after the major political change during the 1970s in the mount…
A lake sediment–based paleoecological reconstruction of late Holocene fire history and vegetation change in Great Basin National Park, Nevada, USA
Analyses of macroscopic charcoal, sediment geochemistry (%C, %N, C/N, δ 13 C, δ 15 N), and fossil pollen were conducted on a sediment core recovered from Stella Lake, Nevada, establishing a 2000 year record of fire history and vegetation change for the Great Basin. Charcoal accumulation rates (CHAR) indicate that fire activity, which was minimal from the beginning of the first millennium to AD 750, increased slightly at the onset of the Medieval …
Making Connections for Our Changing Mountains: Future Directions for the Mountain Research Initiative (MRI)
The Mountain Research Initiative (MRI) promotes basic and applied research to understand how drivers and processes of global change present challenges and opportunities in mountain social-ecological systems. It convenes a global network that collectively generates and synthesizes knowledge on global change in mountains that also supports decisions and actions to enable sustainable development. Building on the considerable social and intellectual …
"Co-producing research in the "Red Zone: Adaptation to fieldwork constraints with a transdisciplinary approach
Fieldwork rarely goes to plan. In geography, anthropology, earth sciences and other research activities that rely on field data, trade-offs are required between planning and execution. This article addresses the adaptation of research projects to changing fieldwork conditions. It is based on a case study of interdisciplinary and international "Coupled Human and Natural Systems" research situated in the Far North of Cameroon. The research project …
Mountain Climatology
Mountain climatology is the study of processes and atmospheric phenomena caused by protrusions of the lithosphere into the atmosphere. The nature and scale of these processes varies, as do the effects, depending on the type of mountains involved and location relative to prevailing winds. Fundamentally, mountains have vertically heterogeneous climatic zones, often capped by snow and ice. The diversity of mountain climates preside over Earth's most…
The significance of mountain glaciers as sentinels of climate and environmental change
Mountain glaciers are transient hydrologic reservoirs persisting at the habitable extremes of Earth that both document and respond to climate change. They withhold water in solid phase from other reservoirs and ultimately impact sea levels. Moreover, they are valued resources with economic and cultural significance for human societies living below them. They also preserve histories of past climates. Yet, when climate change forces glaciers to los…
Impacts of Glacier Recession and Declining Meltwater on Mountain Societies
Glacierized mountains are often referred to as our world's water towers because glaciers both store water over time and regulate seasonal stream flow, releasing runoff during dry seasons when societies most need water. Ice loss thus has the potential to affect human societies in diverse ways, including irrigation, agriculture, hydropower, potable water, livelihoods, recreation, spirituality, and demography. Unfortunately, research focusing on the…
Incorporating Autonomous Sensors and Climate Modeling to Gain Insight into Seasonal Hydrometeorological Processes within a Tropical Glacierized Valley
Peru is facing imminent water resource issues as glaciers retreat and demand for water increases, yet limited observations and model resolution hamper understanding of hydrometerological processes on local to regional scales. Much of current global and regional climate studies neglect the meteorological forcing of lapse rates (LRs) and valley and slope wind dynamics on critical components of the Peruvian Andes' water cycle, and herein we emphasiz…
Social-ecological feedbacks lead to unsustainable lock-in in an inland fishery
A 2000-yr reconstruction of air temperature in the Great Basin of the United States with specific reference to the Medieval Climatic Anomaly
A sediment core representing the past two millennia was recovered from Stella Lake in the Snake Range of the central Great Basin in Nevada. The core was analyzed for sub-fossil chironomids and sediment organic content. A quantitative reconstruction of mean July air temperature (MJAT) was developed using a regional training set and a chironomid-based WA-PLS inference model (r 2 jack = 0.55, RMSEP = 0.9°C). The chironomid-based MJAT reconstruction …
Copper mining on Isle Royale 6500–5400 years ago identified using sediment geochemistry from McCargoe Cove, Lake Superior
Isle Royale, in Lake Superior, contains evidence of indigenous copper mining; however, the timing and geographical extent of mining activity is poorly known. We analyzed metal, carbon, nitrogen, and organic matter concentrations to document past mining pollution in sediment cores recovered from McCargoe Cove; a long, narrow inlet of Lake Superior on Isle Royale that receives drainage from a watershed that contains numerous ancient copper mines. A…
Migration Amidst Climate Rigidity Traps: Resource Politics and Social–Ecological Possibilism in Honduras and Peru
According to dominant narratives about adaptation to climate change, those facing worst-case scenarios, without means at their disposal to adapt in situ, face an ineluctable set of adaptation strategies that ultimately includes the permanent abandonment of geographic spaces rendered uninhabitable and unproductive for human use. Yet environmental stress and adaptive capacity are distributed unevenly, and power structures play a role in fashioning …
New Geographies of Water and Climate Change in Peru: Coupled Natural and Social Transformations in the Santa River Watershed
Projections of future water shortages in the world's glaciated mountain ranges have grown increasingly dire. Although water modeling research has begun to examine changing environmental parameters, the inclusion of social scenarios has been very limited. Yet human water use and demand are vital for long-term adaptation, risk reduction, and resource allocation. Concerns about future water supplies are particularly pronounced on Peru's arid Pacific…
The Nurse's Medication Day
The medication administration stage of the medication-use process is especially vulnerable to error because errors are least likely to be caught before reaching the patient. Medication administration, however, remains poorly understood. In this article we describe medication administration as observed in an ethnographic study conducted on one medical unit and one surgical unit. A central finding was that medication administration entailed a compl…
Climate Change and Tropical Andean Glacier Recession: Evaluating Hydrologic Changes and Livelihood Vulnerability in the Cordillera Blanca, Peru
Climate change is forcing dramatic glacier mass loss in the Cordillera Blanca, Peru, resulting in hydrologic transformations across the Rio Santa watershed and increasing human vulnerability. This article presents results from two years of transdisciplinary collaborative research evaluating the complex relationships between coupled environmental and social change in the region. First, hydrologic results suggest there has been an average increase …
A multi-proxy paleolimnological reconstruction of Holocene climate conditions in the Great Basin, United States
A sediment core spanning ∼ 7000 cal yr BP recovered from Stella Lake, a small sub-alpine lake located in Great Basin National Park, Nevada, was analyzed for subfossil chironomids (non-biting midges), diatoms, and organic content (estimated by loss-on-ignition (LOI)). Subfossil chironomid analysis indicates that Stella Lake was characterized by a warm, middle Holocene, followed by a cool “Neoglacial” period, with the last two millennia characteriz…

Reconstruction of equilibrium-line altitudes for tropical and sub-tropical glaciers
Palaeohydrology of the Southwest Yukon Territory, Canada, based on multiproxy analyses of lake sediment cores from a depth transect
Lake-level variations at Marcella Lake, a small, hydrologically closed lake in the southwestern Yukon Territory, document changes in effective moisture since the early Holocene. Former water levels, driven by regional palaeohydrology, were reconstructed by multiproxy analyses of sediment cores from four sites spanning shallow to deep water. Marcella Lake today is thermally stratified, being protected from wind by its position in a depression. It …
Rates of Deglaciation during the Last Glaciation and Holocene in the Cordillera Vilcanota-Quelccaya Ice Cap Region, Southeastern Perú
Moraine chronology is combined with digital topography to model deglacial rates of paleoglacier volumes in both the Huancané Valley on the west side of the Quelccaya Ice Cap and the Upismayo Valley on the northwest side of the Cordillera Vilcanota. The fastest rates of deglaciation (39×10 −5 to 114×10 −5 km 3 yr −1 and 112×10 −5 to 247×10 −5 km 3 yr −1 for each valley, respectively) were calculated for the most recent paleoglaciers, corresponding…
Subdivision of Glacial Deposits in Southeastern Peru Based on Pedogenic Development and Radiometric Ages
The Cordillera Vilcanota and Quelccaya Ice Cap region of southern Peru (13°30′–14°00′S; 70°40′–71°25′W) contains a detailed record of late Quaternary glaciation in the tropical Andes. Quantification of soil development on 19 moraine crests and radiocarbon ages are used to reconstruct the glacial history. Secondary iron and clay increase linearly in Quelccaya soils and clay accumulates at a linear rate in Vilcanota soils, which may reflect the sem…
