  2. 1. Wild bees in agricultural landscapes: Modelling land use and climate effects across space and time

    Author : Maria Blasi Romero; Centrum för miljö- och klimatvetenskap (CEC); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wild bees; Agricultural landscapes; climate change and agriculture; Phenology; Land-use; Model transferability; Ecological models; Pollination;

    Abstract : Wild bees are declining in many parts of the world, which poses a risk for crop pollination and ecosystem health. Land use and climate change are two of the main drivers of the decline, and understanding the interactive effects of these two drivers and wild bees is very important to be able to develop proper responses and mitigate future negative effects.

    Abstract : A city is considered as a complex system. It consists of numerous interactivesub-systems and is affected by diverse factors including governmental landpolicies, population growth, transportation infrastructure, and market behavior. READ MORE

  5. 3. Land-use and land-cover dynamics and rural livelihood perspectives, in the semi-arid areas of Central Rift Valley of Ethiopia

    Author : Efrem Garedew; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Global environmental changes in climate, land-use and bio-diversity are increasingly on top of scientific and political agenda. The impacts of climate change are manifested on all dimensions of food security: availability, accessibility, utilization and stability. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; urbanization; planning support system; spatial dynamic model; urban land use change; spatial analysis; human-land interaction; socioeconomics; ecological systems; urban amenities; environmental impact assessment; what-if; decision-making; urbanisering; planeringsstödsystem; rumslig dynamisk modell; förändring av stadsmarkanvändning; rumslig analys; mänsklig-land interaktion; socioekonomi; ekologiska system; urbana bekvämligheter; miljökonsekvensbeskrivning; vad-om; beslutsfattande; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : As global urbanization progresses, cities worldwide are growing in size, which leads to many economic, environmental, and management challenges. Recent advancements in spatial data analysis and algorithmic geography have also led to the development of various urban model-based planning support systems (PSS) for urban planning. READ MORE

  7. 5. Environmental Assessment of Emerging Routes to Biomass Based Chemicals The Case of Ethylene

    Author : Christin Liptow; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; sugarcane; time lags; gasification; biomass based chemicals; wood; land use; life cycle assessment; ethylene; LCA;

    Abstract : The production of bulk chemicals from biomass instead of fossil resources is perceived as one promising option to decrease society's environmental impact. However, though considerable research and development efforts aim at such production, it might take several more years before biomass based bulk chemicals are fully commercialized. READ MORE
