Earth Observation in Support of the Sustainable Development Goals
The United Nations 2030 Agenda for Sustainable Development is a global development agenda for the progress on economic, social and environmental sustainability for all countries and stakeholders. Nowadays, most -if not all- Sustainable Development Goals (SDGs) maybe pursued with the robust potential of Earth Observation data and products guaranteeing their applicability both in space and time. This topic focusses on the use of Earth Observation to achieving SDGs and, more specifically, geophysical and climate-related SDGs related to agriculture, water, energy, terrestrial and marine ecosystems, climate change impacts and adaptation, carbon and water footprints, etc. It is desirable that solutions proposed to achieve the SDGs are nature-based solutions that are measures that protect, sustainably manage or restore nature, with the goal of maintaining or enhancing ecosystem services to address a variety of social, environmental and economic challenges (OECD).

Space-based Weather and Climate Extreme Events Monitoring and Forecasting
It is now recognized that there is a need to improve the monitoring of weather and climate from space, especially under severe situations (e.g. extreme rainfall and droughts in particular). Major efforts are being undertaken by WMO, both in improving the infrastructure and expanding surface observations, and in promoting the availability and use of satellite data for different applications (e.g. for weather, hydrological and climate monitoring). The current constellation of satellites and the emerging of new satellite missions carry with them products/algorithms, which are constantly evolving and require careful validation studies for successful applications. These products are becoming more and more robust, with physical-statistical approaches, considering also artificial intelligence (AI) techniques and expanding our spatio-temporal vision, for example, of precipitation and the physical/microphysical processes that involve it, supporting also short-term monitoring and forecasting (nowcasting), making possible the monitoring, also, in areas without in-situ observations. Thus, studies related to observation data from space and products for monitoring climate and weather extremes linked to the proposed themes are welcome

The Continental Water Cycle from Space
Climate, weather, and human life are profoundly affected by changes in Earth's continuous, interconnected "water cycle". Observing and monitoring the key variables governing the global water cycle is essential to our understanding of the Earth's climate, monitoring floods and droughts, and improving water management for human use. The progress of Earth Observation Satellite Technologies (EO) has made it possible since at least the last 40 years to survey several of these key water variables from space. In the coming years, an increasing number of EO missions, like SWOT, will offer an unprecedented capacity to observe the Earth's surface, its interior and the atmosphere, ushering in a new era in the science of the Earth environment and the water cycle. A special focus will be proposed on the application of these techniques in water scarce regions like Nordeste/Ceara and on the detection of the small hydrological entities (small reservoirs, for example) which are a challenge for remote sensing. We encourage presentations on the use of innovative data science methods and artificial intelligence for processing water related satellite data.

Land Use/Cover Changes (LUCC) and Fires
Land-use/cover changes (LUCC) are a paramount concern for the global change research community, with a particular emphasis on South American countries due to the rapid pace of economic development. LUCC encompasses a range of factors and activities that alter the composition and configuration of land and its associated cover, including deforestation, logging, agricultural expansion, and urbanization. The impacts of these activities are far-reaching, affecting ecological systems, biodiversity, climate regulation, and the well-being of local communities. To effectively address and mitigate the consequences of LUCC, it is crucial to comprehensively document these changes. This specific session will focus on mapping, monitoring, drivers, and impacts of LUCC in South American countries using multi-satellite datasets. In addition to several LUCC drivers such as agricultural expansion, forest clearing for plantations, and urbanization, vegetation fires are one of the most significant drivers of forest cover change in the Amazon and other South American countries. In the region, fires are driven by both anthropogenic and climate factors. Remote Sensing technology, due to its multi-spectral, multi-temporal, repetitive, and synoptic coverage, has significant potential to map and monitor fires, including quantifying impacts post-fires. The two-day sessions (August 16 and 17, morning till noon) will focus on LUCC and Fires.
