  1. 1. Urban foodprint - Exploring a design that merges urban landscape and local food production

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : David Einarsson; [2021]
    Keywords : urban design; urban farming; urban agriculture; self-sufficiency; local food production; sustainable development; urbanisation; soil quality; Arts and Architecture;

    Abstract : Globally, there is an intensification of agriculture that puts high pressure on local eco-systems. Soil degradation and deforestation are some effects that in the long-term perspectives cause agricultural degradation. Still, UN projects that we would need to increase our food production by 70 per cent to supply our growing population with food. READ MORE

  2. 2. Farming for food security : a critical study on the transition to post-fossil agriculture in Sweden

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Ebba Ulfbecker; [2018]
    Keywords : agricultural politics; food security; resilience; transition; climate mitigation; agroecology; sustainable intensification; the Rural Development program; contingency; rural development; discourse analysis; policy analysis;

    Abstract : This thesis addresses the preconditions to achieve a transition to fossil free agriculture in Sweden, to increase farm-level resilience and food security. Swedish agriculture is today highly dependent on imported fossil-based inputs, such as diesel, agrochemicals and protein feed. READ MORE

  3. 3. SUSTAINABILITY ASSESSMENT OF DECENTRALISED SOLAR PROJECTS: INTRODUCING A MULTI-CRITERIA APPROACH

    University essay from KTH/Energiteknik

    Author : Ninad Mukul Mutatkar; [2017]
    Keywords : solar energy; rural energy; electrification; sustainability; indicators; multi-criteria;

    Abstract : Lack of energy access in developing countries remains a major barrier in the economic development of rural communities. Worldwide, about 1.3 billion people lack access to modern energy services, and there is a need to pursue ways other than grid extension due to the remoteness of most of these communities from national grids.

  4. 4. Natural migration barriers for fish by hydropower plants : methods to assess historic passability. Case studies of migration barriers

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Johansson Anders; [2016]
    Keywords : natural migration barriers; historic passablility; reference connectivity; connectivity; fish; brown trout; eel; hydropower;

    Abstract : Is it necessary to build fishways at all artificial migration barriers to restore and sustain bio-diversity? Hydropower plants have often been built at places where a difference in height has been used to gain more power, leading to the hypothesis that many hydropower dams have been built at natural migration barriers. How are Swedish running waters (not large rivers) assessed with respect to historical passability for fish at natural migration barriers and dams? How does one study a specific location with respect to the historical passability for different fish species? The methodologies that are evaluated in this thesis are relevant and specific information from a habitat mapping from Värmland County, where 2 903 km waterways already have been surveyed. READ MORE
