Thanks to the advent of the Atacama Large Millimeter/submillimeter Array (ALMA), large surveys of protoplanetary disks in different star forming regions have been carried out to study the gas and dust components simultaneously. Carbon monoxide (CO) and its less abundant isotopologues have been observed to trace the bulk of the gas, while the dust was traced by the (sub-)mm continuum. A result that is common to these surveys is that CO emission from disks is fainter than expected. As a consequence, the overall CO-based gas-masses are very low, often smaller than one Jupiter mass and global gas/dust mass ratios are much lower than the expected interstellar-medium value of 100. This may be interpreted as lack of gas due to fast disk dispersal, or as lack of volatile carbon that leads to faint CO lines. After summarizing the results from different ALMA disk surveys and their implications, I will present alternative observational strategies which may help us to disentangle between the gas dispersal scenario and the chemical evolution hypothesis. More specifically I will show ALMA C2H observations that allow us to constrain the C/O ratio and to confirm that chemical evolution is at play in disks with faint CO lines.

\r\n\r\nThe Atacama Large Millimeter/Submillimeter Array (ALMA) is the world’s most sensitive facility for millimeter/submillimeter astronomical observations, and will soon be fully operational in all of the originally planned bands. Since its first observations, ALMA has routinely delivered groundbreaking scientific results that span nearly all areas of astrophysics.
\r\n\r\nFollowing conferencences in Puerto Varas (Chile, 2012), Tokyo (Japan, 2014), and Indian Wells (USA, 2016), the ALMA partnership is organizing the ALMA Science Conference in Cagliari (Sardinia, Italy) on Oct 14-18, 2019.
\r\n\r\nAt the conference we expect to discuss the full breadth of ALMA science, with special emphasis on results from the first rounds of ALMA Large Programmes, the long baselines and high frequency capabilities, the new Solar and VLBI modes, as well as the synergy between ALMA and other observatories.
\r\n\r\nScience topics will include all fields of astronomy, from cosmology and galaxies in the distant Universe, nearby galaxies and the Galactic Center, interstellar medium and star formation in our Galaxy, astrochemistry, circumstellar disks, exoplanets, solar system, stellar evolution, and the Sun.
\r\n\r\nAs in previous editions of the conference series, we expect to discuss the scientific priorities for the implementation of the ALMA Development Roadmap.
