  1. 1. Assessing water balance and yields in Malawian cropping systems : maize soybean and maize Gliricidia systems resilience against climate change

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Danila Valeriano; [2024]
    Nyckelord :crop modelling; APSIM; Malawi; maize; soybean; Gliricidia; agroforestry; legume intercropping; climate predictions; climate adaptation; SDSM;

    Sammanfattning : In Malawi, maize monocultures are increasingly susceptible to extreme weather patterns, causing considerable yield reduction and heightened food insecurity for smallholder farmers dependent on rainfed subsistence agriculture. Diversifying cropping systems is crucial for ensuring yield resilience. LÄS MER

  3. 2. Can precommercial thinning be used to create more diversity after planting spruce?

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Astrid Bygge; [2024]
    Nyckelord :Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Sammanfattning : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. LÄS MER

  4. 3. Kan samodling av höstraps och utvintrande baljväxter minska angreppen av rapsjordloppa?

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Elin Tegelid; [2023]
    Nyckelord :samodling; rapsjordloppa; utvintrande baljväxter; oljeväxter; raps;

    Sammanfattning : Höstraps (Brassica napus) är en av världens och Sveriges viktigaste grödor. Det är en viktig avbrottsgröda i växtföljder dominerade av spannmål. Tyvärr har den omfattande odlingen gjort att rapsen drabbats av patogener och skadegörare, vilket försvårar ekologisk odling. LÄS MER

  5. 4. Attitudes, existing support and required incentives to increase Continuous Cover Forestry in Sweden

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Victoria Lejon; [2023]
    Nyckelord :Continuous Cover Forestry; Conventional forestry; forest management; Sweden;

    Sammanfattning : An increasing wave of critique against conventional forestry favouring even-aged monoculture plantations and intense ground preparation in Sweden is arising, where some researchers are warning about the negative consequences of the long history of intense forestry and increasing extraction due to the growing demand for bioenergy has caused devastating consequences on ecosystems in forests such as loss of biodiversity. Additionally, reports are revealing that Sweden will not meet its own national environmental goals. LÄS MER

  7. 5. Sweet and Salty: Colonial and Modern Corporate Commodity Exploitation in Northeastern Brazil

    Master-uppsats, Lunds universitet/Mänskliga rättigheter

    Författare :Flavia Copia Sperandio; [2022]
    Nyckelord :modern corporation; sugar cane monoculture; coloniality; rock salt mines; extractivism; Brazil; decolonial theory; business human rights.; History and Archaeology;

    Sammanfattning : This thesis is a historical comparative analysis of the social and environmental impacts of past colonial exploitation and the modern corporate extraction and exploitation of natural resources and commodities. The thesis examines these issues through the case studies of sugar monoculture in the Northeast region of colonial Brazil (16th and 17th Century) and the sinking of Maceió (also in Northeastern Brazil) due to the corporate exploitation of rock salt mines (1976-2019).
