<p>The Copernicus User Uptake Initiative is part of the European Union’s strategy for increasing the level of awareness of the Copernicus Program at European and worldwide level, fostering the adoption of Copernicus-based data/solution in the everyday life of each kind of potential stakeholder, from Local Regional Authorities (LRA) to Big and/or Small Enterprises to normal citizens. The CoRdiNet (Copernicus Relays for digitalization spanning a Network) projects was funded in the frame of Horizon 2020 Space Hubs call (grant agreement n. 821911), to implement and reinforce the user uptake actions among the network of the so called Copernicus Relays. The latter, as part of the Space strategy for Europe of the European Commission, act as Copernicus Ambassadors, providing their contribution for a better dissemination and promotion of Copernicus-based solution at local/regional scale. Among the goals of the Cordinet project there are: i) Supporting, promoting and stimulating digitalization and new business solutions based on Earth observation data from the Copernicus project; ii) bundling the local expertise in the civil use of Earth observation close to the needs and offers of citizens, administration and businesses.</p><p>Earth Observation data from space, in fact, can provide products and services to citizens and can be profitably integrated with non-conventional data, e.g the ones coming from citizen observatories and sciences. However, presently Copernicus data and information are still under-exploited and further efforts are needed to engage stakeholders (including normal citizens), investigating the causes that have prevented from a more systematic and diffuse use of Copernicus/EO data so far. In fact, an increased awareness about the Copernicus program, its data, products and services, will allow for a better integration of non-conventional (e.g. citizen-based) observations, enabling new services and solutions, more close to the citizen needs and requirements for a better quality of life.</p><p>With this aim, one of the tasks of the project was specifically devoted to the identification and engagement of the stakeholders within the CoRdiNet partner geographic regions, including also the external ones involved by a specific call for expression of interest, and it was carried out by TeRN in collaboration with CNR-IMAA. In particular, after their engagement, stakeholders were asked to answer to a questionnaire aimed at analyzing their needs and capabilities and evaluating which barriers have prevented for a more systematic use of Copernicus solutions so far in their own activities. Results achieved analyzing collected feedback will be presented and discussed in this work, providing also a few preliminary recommendations about how to cope with the identified gaps.</p>

The COVID-19 pandemic has infected almost 73 million people and is responsible for over 1.63 million fatalities worldwide since early December 2019, when it was first reported in Wuhan, China. In the early stages of the pandemic, social distancing measures, such as lockdown restrictions, were applied in a non-uniform way across the world to reduce the spread of the virus. While such restrictions contributed to flattening the curve in places like Italy, Germany, and South Korea, it plunged the economy in the United States to a level of recession not seen since WWII, while also improving air quality due to the reduced mobility. Using daily Earth observation data (Day/Night Band (DNB) from the National Oceanic and Atmospheric Administration Suomi-NPP and NO2 measurements from the TROPOspheric Monitoring Instrument TROPOMI) along with monthly averaged cell phone derived mobility data, we examined the economic and environmental impacts of lockdowns in Los Angeles, California; Chicago, Illinois; Washington DC from February to April 2020—encompassing the most profound shutdown measures taken in the U.S. The preliminary analysis revealed that the reduction in mobility involved two major observable impacts: (i) improved air quality (a reduction in NO2 and PM2.5 concentration), but (ii) reduced economic activity (a decrease in energy consumption as measured by the radiance from the DNB data) that impacted on gross domestic product, poverty levels, and the unemployment rate. With the continuing rise of COVID-19 cases and declining economic conditions, such knowledge can be combined with unemployment and demographic data to develop policies and strategies for the safe reopening of the economy while preserving our environment and protecting vulnerable populations susceptible to COVID-19 infection.

Urban forests contribute significantly to the ecological integrity of urban areas and the quality of life of urban dwellers through air quality control, energy conservation, improving urban hydrology, and regulation of land surface temperatures (LST). However, urban forests are under threat due to human activities, natural calamities, and bioinvasion continually decimating forest cover. Few studies have used fine-scaled Earth observation data to understand the dynamics of tree cover loss in urban forests and the sustainability of such forests in the face of increasing urban population. The aim of this work was to quantify the spatial and temporal changes in urban forest characteristics and to assess the potential drivers of such changes. We used data on tree cover, normalized difference vegetation index (NDVI), and land cover change to quantify tree cover loss and changes in vegetation health in urban forests within the Nairobi metropolitan area in Kenya. We also used land cover data to visualize the potential link between tree cover loss and changes in land use characteristics. From approximately 6600 hectares (ha) of forest land, 720 ha have been lost between 2000 and 2019, representing about 11% loss in 20 years. In six of the urban forests, the trend of loss was positive, indicating a continuing disturbance of urban forests around Nairobi. Conversely, there was a negative trend in the annual mean NDVI values for each of the forests, indicating a potential deterioration of the vegetation health in the forests. A preliminary, visual inspection of high-resolution imagery in sample areas of tree cover loss showed that the main drivers of loss are the conversion of forest lands to residential areas and farmlands, implementation of big infrastructure projects that pass through the forests, and extraction of timber and other resources to support urban developments. The outcome of this study reveals the value of Earth observation data in monitoring urban forest resources.
