The effects of climate change, whether they be via slow- or rapid-onset events such as extreme events, are inflicting devastating losses and damage on communities around the world, with most vulnerable affected most. Although negative impacts change concept loss included in international conventions, United Nations Warsaw International Mechanism for Loss Damage Article 8 Paris Agreement, these stop short providing clear compensation mechanisms. science has evolved development event...
Significance Freshwater appropriation can have vast impacts, depending on management and scale of water use. Since 2000, foreign investors contracted an area the size United Kingdom in Africa, leading to increased pressure resources. Here we couple site-specific demand for crops planted there efficiency different irrigation systems, while relating these estimates local availability. This approach enables us identify “hotspot” areas freshwater use where more from than be supplied by soil...
Global land acquisitions, often dubbed 'land grabbing' are increasingly becoming drivers of change. We use the tools network science to describe connectivity global acquisition system. find that 126 countries participate in this form trade. Importers concentrated North, emerging economies Asia, and Middle East, while exporters confined South Eastern Europe. A small handful account for majority acquisitions (particularly China, UK, US), cumulative distribution which is best described by a...
This study investigates annual water balance conditions and their spatiotemporal variability under a wide variety of atmospheric driving in the periglacial permafrost catchment Two Boat Lake Western Greenland. The uses combines comprehensive hydrological multi-parameter dataset measured at site with conceptualization numerical model development, application testing. result reproduces lake groundwater levels, as well observations made by time-lapse cameras. results highlights importance...
Abstract Aim To test if a phytoplankton bloom is panmictic, or whether geographical and environmental factors cause spatial temporal genetic structure. Location Baltic Sea. Method During four cruises, we isolated clonal strains of the diatom Skeletonema marinoi from 9 to 10 stations along 1132 km transect analysed structure using eight microsatellites. Using F ‐statistics Bayesian clustering analysis determined samples were significantly differentiated. A seascape approach was applied...

Groundwater and surface-water interactions are regulated by catchment characteristics complex inter- intra-annual variations in climatic conditions that not yet fully understood. Our objective was to investigate the influence of freeze-thaw processes on surface groundwater a boreal landscape, Krycklan Sweden. We used numerical modelling approach sub-catchment evaluation method identify evaluate fundamental processes. The model reproduced observed stream discharge patterns 14 sub-catchments...

Negative trends of climate change and biodiversity loss are closely linked with farming practices, it is therefore essential to re-think how agricultural systems can sequester more carbon, simultaneously create vital ecosystems. The overall aim this research imagine Swedish farms as carbon sinks rather than sources, re-design the current farm- food system also address other social, economic, environmental sustainability challenges. This paper outcome two visioning workshops together...
Agroecology is increasingly promoted as a way to create just and sustainable farm- food systems. Although there are multiple initiatives scale up agroecology, current socio-political structures often hinder its potential transform This study uses participatory approaches paintings that envision agroecological futures in the context of increased farmer-pastoralist collaborations Tanzania, how they would function, what political action needed support such futures. The visions based on focus...
Abstract. Few hydrological studies have been conducted in Greenland, other than on glacial hydrology associated with the ice sheet. Understanding permafrost and hydroclimatic change variability, however, provides key information for understanding climate effects feedbacks Arctic landscape. This paper presents a new, extensive, detailed meteorological open access data set, high temporal resolution from 1.56 km2 catchment, lake underlain by through-talik close to sheet Kangerlussuaq region,...
Abstract. Global warming is expected to be most pronounced in the Arctic where permafrost thaw and release of old carbon may provide an important feedback mechanism climate system. To better understand predict effects feedbacks on cycling elements within between ecosystems northern latitude landscapes, a thorough understanding processes related transport required. A fundamental requirement reach process have access high-quality empirical data chemical concentrations biotic properties for...
Large-scale land acquisitions are a critical driver of global socio-environmental change, in particular the Global South. This study aims to investigate drivers, impacts and feedbacks environmental change Kilombero Valley, Tanzania, region rapid societal transformation. We use cover classifications map quantify changes from 1990 2016, compare these with local perceptions fieldwork conducted 2015 2016. The detection clearly shows farmland expansion over wetlands, which is line perceptions,...
Changing rainfall patterns make farmers increasingly vulnerable to crop failure, income loss and food insecurity. Agroecology is proposed reduce climate vulnerabilities of farmers, as such practices social movement aim create more resilient farm systems. It however fairly unknown if, what extent, agroecological are better able cope with induced exposures compared conventional smallholders. We conducted 194 surveys smallholders explore the three components vulnerability: exposure, sensitivity...
Abstract Rapid deforestation is a major sustainability challenge, partly as the loss of carbon sinks exacerbates global climate change. In Cambodia, more than 13% total land area has been contracted out to foreign and domestic agribusinesses in form economic concessions, causing rapid large-scale use change deforestation. Additionally, distant drivers local environmental often remain invisible. Here, we identify hotspots between 1987–2017 using dynamic vegetation model LPJ-GUESS by comparing...
