  2. 2. Dynamics of net primary production and food availability in the aftermath of the 2004 and 2007 desert locust outbreaks in Niger and Yemen

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Emma Bylund; [2021]
    Nyckelord :geography; GIS; desert locust outbreak; NPP; food availability; livelihood zones; Earth and Environmental Sciences;

    Sammanfattning : The knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. LÄS MER

    Sammanfattning : There has recently been an increased interest in hydrogen, both as a solution for seasonal energy storage but also for implementations in various industries and as fuel for vehicles. The transition to a society less dependent on fossil fuels highlights the need for new solutions where hydrogen is predicted to play a key role. LÄS MER

  5. 5. Towards Regenerative (Agri)Cultures. An ethnographic case study of integrated socio-ecological restoration at the Hof Lebensberg community farm, Germany

    Master-uppsats, Lunds universitet/LUCSUS
