The Brazilian project Carne Carbono Neutro (CCN) assumes that a more sustainable beef will increase its value for the consumers. The paper aims to verify this assumption and to suggest a communication strategy supporting the CCN valorization. An online survey involving 506 Brazilian consumers showed three different classes of consumers with significantly different attitudes towards environmental issues. Price and quality always strongly influence their demand for beef. A communication campaign should focus on the CCN lower beef environmental impact and beef price/quality issues. Social media on internet and education programs in schools and different institutions should be used. International Journal on Food System Dynamics, Vol 11, No 4 (2020)

The INTENSSS PA project, funded by Horizon 2020, the Framework Programme for Research and Innovation of the European Union, aims to support the local authorities involved and their stakeholders to develop an innovative integrated sustainable energy planning concept through a participatory, interdisciplinary and multilevel process. By building individual and institutional capacity of the actors involved, using the Regional Living Lab approach, the concept will be applied in order to develop seven sustainable integrated energy plans. In this first article the project activities and the results achieved so far are preliminary described, anticipating a more extensive and detailed publication on the project planned for the December edition of UPLand – Journal of Urban Planning Landscape & Environmental Design.

Perennial rhizomatous grasses (PRGs) are seen as a feasible opportunity to produce second generation biofuels. Among PRGs, giant reed (Arundo donax L.) is a promising energy crop, particularly for the Mediterranean environment characterized by low precipitation and high evapotranspiration rates during the summer period. The species is in fact robust and able to thrive in a wide range of soil types and under drought conditions. However, it remains a major challenge to better understand the yield potential and the crop responses to marginal soils, such as those where water and nutrients may represent limiting factors. In this work we evaluated giant reed aboveground and belowground biomass partitioning, from the establishment to the third year, in a marginal soil. Giant reed showed a significant increment of the rhizome biomass, reaching values of about 16 t ha-1 in the third year. Maximum total aboveground biomass increased steeply from the first to the second year, while a slight increase was highlighted from the second to the third one (20 t ha-1). Furthermore, our data suggest that, in a limiting environment, after three years the crop was not fully established yet. In conclusion, giant reed shows quite a good adaptability to marginal land, in particular those characterized by a low water retention capacity.

Climate change is a current phenomenon: the temperatures rise, rainfall patterns are changing, glaciers melt and the average global sea level is rising. It is expected that these changes will continue and that the extreme weather events, such as floods and droughts, will become more frequent and intense. The impact and vulnerability factors for nature, for the economy and for our health are different, depending on the territorial, social and economic aspects. The current scientific debate is focused on the need to formulate effective policies for adaptation and mitigation to climate change. The city plays an important role in this issue: it emits the most greenhouse gas emissions (more than 60% of the world population currently lives in urban areas) and the city is more exposed and vulnerable to the impacts of climate change. Urban planning and territorial governance play a crucial role in this context: the international debate on the sustainability of urban areas is increasing. It’s necessary to adapt the tools of building regulations to increase the quality of energy - environment of the cities. Tema.

The solar radiation is a critical input parameter when working with solar energy and radiation dependent surface processes. In this study, we present preliminary results from an inter-comparison between hourly values from a pyranometer, MSG-SEVIRI sensor and two meso-scale models, WRF and RAMS, in clear and cloudy sky conditions. Cloudy sky condition is the most important because the attenuation of solar radiation in the atmosphere is strongly dependent on the cloud variability. Bias and RMSE errors are evaluated at a coastal site in the Mediterranean area. These statistics show the tendency of both models to overestimate short-wave radiation.

The relationship between cities and energy consumption has been of great interest for the scientific community for over twenty years. Most of the energy consumption, indeed, occurs in cities because of the high concentration of human activities. Thus, cities are responsible for a big share of carbon dioxide emissions (CO2). However, the debate on this topic is still open, mainly because of the heterogeneity of published studies in the selection, definition and measurement of the urban features influencing energy consumption and CO2 emissions, as well as in the choice of the energy sectors to be considered, in the territorial scale of analysis, and in the geographical distribution of the sample. Therefore, the goal of this research is to systematize and compare the approach, methodology and results of the relevant literature on the relationship between cities and energy consumption over the last twenty years. Furthermore, this critical review identifies the knowledge gap between what is known and what is still under debate and, based on that, it proposes a conceptual framework that will help to outline a new direction for future research and support local policy makers in the definition of strategies and actions that can effectively reduce urban energy use and CO2 emissions.

The functioning of food value chains entails a complex organisation from farm to fork which is characterised by various governance forms and externalities which have shaped the overall food system. VALUMICS food value chain case studies: wheat to bread, dairy cows to milk, beef cattle to steak, farmed salmon to fillets and tomato to processed tomato were selected to enable explorative and empirical analysis to better understand the functioning of the food system and, to identify the main challenges that need to be addressed to improve sustainability, integrity, resilience, and fairness of European food chains. The VALUMICS system analysis was executed through four operational phases starting with Groundwork & analysis including mapping specific attributes and impacts of food value chains and their externalities. This was followed by Case study baseline analysis, which provided input to the third phase on Modelling and exploration of future scenarios and finally Policy and synthesis of the overall work. This report is an overall synthesis of the VALUMICS results as follows: • Key findings from the VALUMICS project on the functioning of European food value chains and their impacts on more sustainable, resilient, fairer, and transparent food system are summarised through a compilation of 25 Research Findings and Policy Briefs. • By highlighting the major contributions from the research activities throughout the four phases of the VALUMICS project, this report delivers an assessment of various factors influencing sustainability, resilience, efficiency and fairness and effective chain relationships of different food value chains, and their determinants. • The synthesis of the outcome allows the identification of opportunities and challenges characterising the functioning of food supply chains, and thus, the prospects and potentials for strengthening the EU food sector.

Urbanization is an onerous human activity: it affects municipal budget and foremost it costs the environment. Nevertheless, an ever-growing number of people (more than 75% of the European population) is living in cities and towns, so that identifying sustainable urban development solutions is a dramatically urgent need. Already in the 70s, some researches proposed parameters to evaluate urbanization costs in Italy, but they mainly focused on the economic and financial sustainability of real estate development. The land value capturing approaches proved to be inadequate when municipal budgets are facing growing social unbalances and critical environmental threats. The question being not just “where the money for urban infrastructures could come from”, but also “what could be a more sustainable development model”. In any case, now we are forced to rethink the whole organization of our urban life to defend ourselves from largely unknown threats, pandemics, COVID-19 being probably one among others that we could face in the near future. It is not yet clear if a link exists between the spread of the virus, the health consequences and the environmental conditions, but what probably will need to be assessed is the effect of population density on the spread of contamination. Even the traditional provision of services and public spaces will need to be defined again in order to protect and serve urban population. New evidences will force planners to redefine their thoughts and schemes. TeMA - Journal of Land Use, Mobility and Environment, 2020: Special Issue. Covid-19 vs City-20
