Impacts of dams on lowland agriculture in the Mekong River catchment

På den Indokinesiska halvön ligger Mekongflodens avrinningsområde. De senaste årtiondena har Kina, som innehar den nordligaste delen av flodbassängen, startat ett omfattande vattenkraftsprojekt på flodens huvudfåra. Åtta mycket stora dammar är planerade varav tre redan är byggda. Länderna som ligger nedströms från Kina, nämligen Laos, Kambodja och Vietnam har på senare tid också beslutat att bygga

Optimization of water intake systems : Based on water-carbon relationships and sustainable development goals

Achieving sustainable development goals requires strategically balancing the trade-off between water resource utilization and carbon emissions. It is of particular importance to systematically study the relationships between water conservation and emission reduction (water-carbon relationship) in a water intake system, and to optimize the water intake structure accordingly. This study proposes a m

A new implementation of FLEXPART with Enviro-HIRLAM meteorological input, and a case study during a heavy air pollution event

We integrated Enviro-HIRLAM (Environment-High Resolution Limited Area Model) meteorological output into FLEXPART (FLEXible PARTicle dispersion model). A FLEXPART simulation requires meteorological input from a numerical weather prediction (NWP) model. The publicly available version of FLEXPART can utilize either ECMWF (European Centre for Medium-range Weather Forecasts) Integrated Forecast System

Mapping soil cadmium content using multi-spectral satellite images and multiple-residual-stacking model : Incorporating information from homologous pollution and spectrally active materials

Soil cadmium (Cd) contamination significantly threatens ecosystems and human health. Traditional geochemical investigation, although accurate, is impractical for wide-area and frequent monitoring applications. Multi-spectral satellite images combined with the homologous pollution information (HPI) and the spectral and content information of soil organic matter (SOMSCI) is an unconventional and pro

Wetland types and soil properties shape microbial communities in permafrost-degraded swamps

Global warming has accelerated permafrost degradation, destabilizing soil organic carbon (SOC) in wetlands. Soil microorganisms play a crucial role in SOC decomposition. Despite increasing studies on soil microorganisms and their associated impacts on SOC decomposition in wetlands, few studies have simultaneously investigated the impacts of soil physical properties and nutrient stoichiometry on so

SRPNet : stroke risk prediction based on two-level feature selection and deep fusion network

Background: Stroke is one of the major chronic non-communicable diseases (NCDs) with high morbidity, disability and mortality. The key to preventing stroke lies in controlling risk factors. However, screening risk factors and quantifying stroke risk levels remain challenging. Methods: A novel prediction model for stroke risk based on two-level feature selection and deep fusion network (SRPNet) is

Isolation, Behavioral Identification, and Pathogenicity Assessment of Entomopathogenic Fungi from a Forest Wood Borer

Forest wood borers (FWB) cause severe tree damage and economic losses worldwide. The release of entomopathogenic fungi (EPF) during the FWB emergence period is considered an acceptable alternative to chemical control. However, EPF resources have been significantly less explored for FWBs, in contrast to agricultural insect pests. This paper presents a protocol for exploring EPF resources from FWBs

Urban Ecosystem Vulnerability Assessment of Support Climate-Resilient City Development

Climate change poses a threat to cities. Geospatial information and communication technology (Geo-ICT) assisted planning is increasingly being utilised to foster urban sustainability and adaptability to climate change. To fill the theoretical and practical gaps of urban adaptive planning and Geo-ICT implementation, this article presents an urban ecosystem vulnerability assessment approach using in

Accurate quantification of soil organic matter content using VNIR-SWIR spectra : The role of straw and spectrally active materials

Soil organic matter (SOM) is crucial for carbon sequestration and sustainable agriculture, yet traditional quantification methods are challenging to apply at large scales. Hyperspectral technology combined with machine-learning offers promising prospects for rapid quantification. This study explores the impact of using VNIR-SWIR spectra on SOM quantification in regions characterized by distinctive

The Top Runner policy concept: Pass it down?

In the 1990s, Japanese energy regulators were concerned by the fact that new generations of energy using appliances and products no longer displayed successive use-phase energy efficiency improvements, such as those that characterised product development in Japan after the 1970s oil crises. Therefore, in 1999, Japan incepted its Top Runner programme, designed to rejuvenate the lost momentum. Sever

Contrasting phenology responses to climate warming across the northern extra-tropics

Climate warming has substantially advanced the timing of spring leaf-out of woody species at middle and high latitudes, albeit with large differences. Insights in the spatial variation of this climate warming response may therefore help to constrain future trends in leaf-out and its impact on energy, water and carbon balances at global scales. In this study, we used in situ phenology observations

Global growth and stagnation of nuclear power - A case of diffusion of a new energy technology in a heterogenous system

Reaching the targets of the Paris Agreement requires acceleration of low-carbon energy transitions. At the same time, it is not fully understood why some technologies spread more rapidly and widely than others. This thesis advances our understanding of the diffusion of large-scale low-carbon technologies by bridging technology diffusion studies and political economy of transitions. Through combini

Gaseous mercury distribution in the upper troposphere and lower stratosphere observed onboard the CARIBIC passenger aircraft

Total gaseous mercury (TGM) was measured onboard a passenger aircraft during monthly CARIBIC flights (Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrumented Container) made between May 2005 and March 2007 on the routes Frankfurt-Sao Paulo-Santiago de Chile and back and Frankfurt-Guangzhou-Manila and back. The data provide for the first time an insight into the seasonal

A deep genealogy of Japanese green nationalism from the long 19th century to the present

Employing the term “green nationalism” in the broad sense of nationalist ideologies that concern themselves with the natural environment, we trace a genealogy of green nationalist thought in Japan back to the start of the long 19th century. The changing contours of this discourse are mapped through five representative writers: Moto'ori Norinaga (1730–1801), Shigetaka Shiga (1863–1927). Testurō Wat
