The gathering features leading scientists and policymakers reviewing the current state of knowledge and presenting significant new developments in policy, measurement, modelling, mitigation and adaptation efforts associated with greenhouse gases from animal agriculture. The Conference takes place every 3 years, moving from continent to continent at each edition. The first conference, GGAA2003, was held in Japan with 200 delegates from 20 countries. Five subsequent GGAA conferences have been convened: GGAA2005, Switzerland; GGAA2007, New Zealand; GGAA2010, Canada, with the biggest in Ireland, GGAA2013, attracting 460 delegates from 41 countries. The GGAA2016 in Australia received more than 300 delegates from 36 countries. GGAA2019 The GGAA2019 focused on the theme “Science supporting Practices” and happened for the first time in Latin America. Following on from the six previous GGAA conferences, presented the latest research on the measurement, modelling, mitigation of greenhouse gases, while also seeking to discuss adaptation efforts and the impact of these advances for farmers, managers and policy makers. At the GGAA2019 conference, held in Iguassu Falls, Brazil, almost 200 delegates from 39 countries gathered to participate in a program featuring 11 invited keynote speakers, 47 offered presentations and 111 poster presentations. The conference was organised into four sessions covering: Technical advances: from genomics to precision agriculture, that addressed aspects related to Measuring and Modelling GHG; Farm level low carbon initiatives, which addressed Mitigation and Adaptation strategies to provide more Resilient production systems; Regional low carbon initiatives, which considered the Landscape, Regional management and National Commitments; International low carbon initiatives, that presented examples from IPCC, NDCs, FAO, World Bank. Delegates were offered the opportunity to publish their research in this peer-reviewed Special Edition of Animal, Cambridge University Press, with all abstracts published in conference proceedings. Volume One of the GGAA2019 Special Edition will include 20 peer-reviewed papers and will be available within the last quarter of 2019. The ‘virtual’ Volume Two will present the Proceedings… in a digital way, available in the web site. Taken together, these special editions provide the latest summary of the current state of knowledge on policy developments, measurement, modelling, mitigation and adaptation efforts associated with greenhouse gases from animal agriculture. VENUE The city of Iguassu Falls was selected to host the event for the first time in Latin America thanks to its excellent geographical location within the triborder region of Brazil, Argentina and Paraguay. The city boasts an international airport that connects to the leading international airports in South America and can easily be reached by Latin American participants via bus or car. Besides the facilitated access, Iguassu Falls is further complemented by technical and scientific attractions part of the context of the conference, such as waterfalls, a national park, bioenergy and hydroelectric complex which were included as technical visits.
