1. 21. Environmental issues from sugarcane plantations in Brazil and how to handle them with market-based instruments

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Freja Milton; [2019]
   Keywords : Market-based instruments; environmental offsets; Payments for ecosystem services; PES; Brazil; bioplastic; biopolymer; sugarcane; certification; environmental impacts from sugarcane cultivations.; Earth and Environmental Sciences;

   Abstract : This study is a literature review of three market-based instruments used for land management; environmental offsets, payments for ecosystem services (PES) and certification, and how they could be used to mitigate environmental impacts from sugarcane cultivation in Brazil when purchasing biopolymers. The study showed that certification is the most common market-based instrument in Brazil. READ MORE

3. 22. An IoT Solution for Urban Noise Identification in Smart Cities : Noise Measurement and Classification

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Yasser Alsouda; [2019]
   Keywords : urban noise; sound pressure level SPL ; internet of things IoT ; machine learning; support vector machine SVM ; k-nearest neighbors KNN ; bootstrap aggregating Bagging ; random forest; mel-frequency cepstral coeffi-cients MFCC ;

   Abstract : Noise is defined as any undesired sound. Urban noise and its effect on citizens area significant environmental problem, and the increasing level of noise has become a critical problem in some cities. Fortunately, noise pollution can be mitigated by better planning of urban areas or controlled by administrative regulations. READ MORE

4. 23. Mobility-as-a-Service (MaaS) from a Transport Operator’s Perspective : Opportunities and challenges

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Magnus Sellstedt; Andreas Sjöling; [2019]
   Keywords : Integrated mobility services; Mobility as a service; MaaS; transportation operators; business models; networked business models.; Integrerade mobilitetstjänster; Mobilitet som tjänst; MaaS; transportoperatörer; affärsmodell; nätverksbaserad affärsmodell.;

   Abstract : Congestion and pollution are challenges that have started to build pressure on urban cities to introduce more environmental-friendly transportation alternatives. One transport solution that has gained attention in the light of digitalization is a concept called mobility as a service (MaaS) that has the potential to change how people travel today. READ MORE
