  1. 1. Increasing crop yields under climate change scenarios in Nigeria

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Imogen O'Keefe; [2020]
    Keywords : Physical Geography; Agriculture; Climate Change; Crop Yields and Management Strategies; Earth and Environmental Sciences;

    Abstract : Climate change is projected to cause unprecedented levels of global change and it will alter the ways in which humans currently rely on getting essential resources such as food. Africa is considered to be the most vulnerable continent to this change, with many countries that have low economic stability and insecure food sources a change to the way resources can be accessed could be detrimental to the population.

  2. 2. Wild Seaweed Harvesting: "The Next Big Industry in Iceland”? Ways to encourage sustainable harvesting and improve the regulatory framework on seaweed

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Ásta Maack; [2019]
    Keywords : Wild Seaweed; Seaweed Havresting; Natural Resource Management; Regulatory framework; Seaweed Regulation; Iceland; Social Sciences;

    Abstract : Brown seaweed or macro-algae are multicellular plant-like organisms that inhabit various shores surrounding West-America and Northern Europe. Seaweed deliver highly important ecosystem services and provide habitats and shelter for other species, serving as a food source and take part in the nutrient recycling of Silica, Phosphorus and Nitrogen on land and in the sea.

  3. 3. Agricultural Agglomeration Infrastructure and Agricultural market integration for emergent farmers

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Nikolaj Tetzlaff; [2019]
    Keywords : Spatial Economics; Infrastructure; Economic Development; Agricultural Transformation; Business and Economics;

    Abstract : This thesis seeks to explain constraining effects of distance to markets on agricultural smallholder’s ability to commercialise, using Zambia as a case. Despite a growing consensus that inaccessible markets constrain the development of broad-based agricultural growth, creating socio-economic regional disparities, the exact nature by which distance and market access interact with agricultural producers remains under-examined.

  4. 4. Dissolution rates of mineral nitrogen fertilisers : effects of moisture and precipitation

    University essay from SLU/Dept. of Soil and Environment

    Author : Christian Sigtryggsson; [2018]
    Keywords : hygroscopicity; deliquescence; fertilisers; calcium nitrate; ammonium nitrate; dissolution rates; rain simulation; enthalpy; precision fertilisation;

    Abstract : Hygroscopicity and deliquescence refer to the ability of a solid to absorb air moisture in which it dissolves and have long been recognised as properties having negative impacts on the product quality of explosives, pharmaceuticals, and fertilisers. Contrastingly, this thesis reconsiders and reappraises the hygroscopic effects of common mineral fertilisers, proposing hygroscopicity to beneficially enable quick dissolution under humid air conditions in absence of precipitation.

  5. 5. Environmental Impact Analysis of Flax Fibre Cultivation for Composite Reinforcement

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : Elin Jacobsson; [2018]
    Keywords : flax fibre; life cycle assessment; reinforcement; environmental impact assessment;

    Abstract : Searching for environmentally sustainable alternatives for reinforcement of composite materials, flax fibre has one of the most promising potentials due to its desired mechanical properties. The fact that flax is a bio-material, in contrast to conventional synthetic fibres, does not ensure a less environmental impact. READ MORE
