Application of mixed-effects modelling and rule-based models to explain copper variation in soil profiles of southern Germany
(2022-05-25)
Copper (Cu) is an essential element for plants and microorganisms and at larger concentrations a toxic pollutant. A number of factors controlling Cu dynamics have been reported, but information on quantitative relationships is scarce. We aimed to (i) quantitatively describe and predict soil Cu concentrations (CuAR) in aqua regia considering site-specific effects and effects of pH, soil organic carbon (SOC) and cation exchange capacity (CEC), and (ii) study the suitability of mixed-effects modelling and rule-based ...

Impact of Cropping Pattern and Climatic Parameters in Lower Chenab Canal System - Case Study from Punjab Pakistan
(2022-05-17)
In Pakistan, groundwater resources are depleting at an alarming rate due to intensive pumping, shifting of cropping patterns, and climate change vulnerability. The present study is aimed at investigating groundwater stress in the command area of Lower Chenab Canal (LCC) and associated branch canals. Groundwater stress is determined by considering the cropping patterns, surface water availability, groundwater levels, climatic variation, and crop water requirement (CWR) in the LCC command area. The climatic data is ...

Millimetre scale aeration of the rhizosphere and drilosphere
(2022-06-22)
Soil aeration is a critical factor for oxygen-limited subsoil processes, as transport by diffusion and advection is restricted by the long distance to the free atmosphere. Oxygen transport into the soil matrix is highly dependent on its connectivity to larger pore channels like earthworm and root colonised biopores. Here we hypothesize that the soil matrix around biopores represents different connectivity depending on biopore genesis and actual coloniser. We analysed the soil pore system of undisturbed soil core ...

Collaborative agroforestry to mitigate wildfires in Extremadura, Spain: land manager motivations and perceptions of outcomes, benefits, and policy needs
(2022-10-10)
Wildfires are increasing in severity, and magnitude in the Mediterranean Basin in recent years, reaching a yearly average of 450 000 ha over the last decade. Drivers include climate change, land-use change, and land abandonment. Wildfire mitigation requires landscape-level action as impact to each parcel is affected by the conditions of the others. We conducted a case study of a regional-level initiative that develops community efforts to mitigate wildfires through silvo-pastoral agroforestry systems, using an ...

Spatially explicit life cycle assessments reveal hotspots of environmental impacts from renewable electricity generation
(2022-08-30)
Renewable energy generation has great potential to reduce greenhouse gas emissions, however, it may exacerbate other environmental impacts, such as water scarcity, elsewhere in the supply chain. Here, we reveal a wide range of global environmental impacts of concentrated solar power, run-of-river hydropower, and biomass burning compared to classical coal-fired power: Spatially explicit life cycle impact assessment is used to evaluate their supply chains with respect to demand for energy, land, material, and water, ...

An interdisciplinary assessment of private conservation areas in the Western United States
(2020-02-20)
Conservation easements are the fastest growing private conservation strategy in the United States. However, mechanisms to assess private land conservation as well as their support by the general public are not well understood. This study uses the ecosystem services framework for assessing existing private lands in Idaho and identifies areas for future conservation easements. Using conservation targets of the land trust as a guide for selecting ecosystem services, we (a) mapped the spatial delivery of conservation ...

Extended life cycle assessment reveals the spatially-explicit water scarcity footprint of a lithium-ion battery storage
(2021-01-12)
The life cycle water scarcity footprint is a tool to evaluate anthropogenic contributions to regional water scarcity along global supply chains. Here, we complement it by a classification of the risk from human water use, a comprehensive conceptualisation of water use and a spatially-explicit impact assessment to a midpoint approach that assesses the risk of on-site and remote freshwater scarcity. For a 2 MWh Lithium-ion battery storage, the quantitative Water Scarcity Footprint, comprising physically used water, ...

Rurbanity: a concept for the interdisciplinary study of rural–urban transformation
(2023-05-20)
Along with climate change, population growth, and overexploitation of natural resources, urbanisation is among the major global challenges of our time. It is a nexus where many of the world’s grand challenges intersect, and thus key to sustainable development. The widespread understanding of urbanisation as a successive and unidirectional transformation of landscapes and societies from a rural to an urban state is increasingly questioned. Examples from around the globe show that ‘the rural’ and ‘the urban’ are not ...

Human‑elephant conflict in the Sri Lankan dry zone: investigating social and geographical drivers through field‑based methods
(2023-07-02)
Human-elephant conflict (HEC) in Sri Lanka has escalated over the recent years, with, on average, 300 elephant deaths annually and human casualties of around 90 per year. Employing field-based qualitative methods, this contribution identifies causes and contexts of human-elephant conflict in those parts of the Sri Lankan dry zone most severely affected. We have used field observations as well as semi-structured interviews with experts and affected villagers as primary data collection techniques. The findings show ...

Drought threatens agroforestry landscapes and dryland livelihoods in a North African hotspot of environmental change
(2024-02-08)
Dryland agroforestry is often hailed as a nature-based solution for rural people’s water- and climate-related struggles, yet appraisals of traditional agroforestry practices and interventions in Maghreb countries are scant. In this study, we appraise whether and how agroforestry delivers as a solution to Moroccan farmers’ plight with drought. Through an analysis of landscape observations, 75 qualitative interviews, and six group discussions, we show that the region’s mountain residents risk losing their livelihoods ...
