Postcard from Mesoamerica
As Geography research begins in the field and ends in the field, so does my Presidential Column. I had the good fortune to be able to compose most of my first column (July 2018) during my fieldwork in Belize and Guatemala in Central America. Now I am filing my final column as your AAG President from field camp in northwestern Belize, working with an international team of colleagues, students, and volunteers to study the resilience of ancient Maya society. While “Op-Ed” stands for Opinion/Editorial, it also represents both Opportunity and Education. I thank you, my readers and fellow AAG members, for the Opportunity to freely explore challenging and timely issues and to share thoughts and opinions on current events and research over the last year. I am also grateful for the platform of the AAG Newsletter on which to perform one of my primary duties as a Professional Geographer: to Educate, to enable understanding and discussing important issues from local to global scales, and, to inspire actions to solve the planet’s most critical human and environmental problems. It is a tall order, but we should set expectations for ourselves at the very highest level to ensure a better future for people, the environment, and the planet.
This is my 26th field year exploring the palimpsests of millennia of urban and agricultural landscapes of parts of modern Mexico, Belize, and Guatemala. Each year we discover more about how extensive and influential ancient humans have been in the Americas. We have increased our understanding of human influences on the earth, from William Denevan exploding the Pristine Myth in the 1992 Annals Special issue (82(3):369-85), to the 2013 dawning of the journal The Anthropocene, (Anne Chin, Editor-in-Chief), to the May 2019 binding vote of the Anthropocene Working Group approving that the Anthropocene shall be “treated as a formal chrono-stratigraphic unit” and its primary marker will be “one of the stratigraphic signals around the mid-twentieth century of the Common Era” (AWG, 5/21/19). It is still a complicated matter of agreeing when that marker occurs in time globally. While the swirling smog of the 19th C. Industrial Revolution was a leading, if not charismatic, candidate, not to mention the globally detectable nuclear testing fallout signal of the mid-20th C., evidence still builds for an Early Anthropocene. Denevan’s idea (1992) that 18th century human visibility on the landscape was less substantial than that which was visible before 1492 still stands the test of time, further supported by W. F. Ruddiman et al.’s 2016 work (Rev. Geophys. 54: 93-118) on early, increased releases of CO2 and Methane to the atmosphere associated with increased burning and farming like rice paddy (wetland) agriculture in Asia. Now with advanced geospatial technology such as Lidar guiding our field exploration and validation, we are fast on the trail of finding significant extents of ancient landesque capital, including cultivated landscapes, ranging far across the Western Hemisphere, including Mesoamerica. Much else has changed in field research infrastructure since the early 1990s: Quad maps in Belize were produced for us in 1993 as Ozalid blueprints in the Government Mapping Office in Belmopan. Now there is a Land Information Center providing geospatial data. In 1994, a colleague mounted a brick-shaped GPS unit on an extension pole in the jungle, trying to reach a satellite signal at just the right hour. For communications, there was a payphone and one fax machine in the general store in the village near our field camp, a lifeline for college students with final papers due who were here in the field to collect data before the rainy season hit. Now we despair that the local internet is not working today in camp. Yet, there are some regions here in Belize and beyond still too remote to access cell service, allowing us a moment to also rejoice that there are places untouched by clouds of 4G data smog to walk through and be interrogated by.
My last official duty as AAG President will take place at the end of June, when I travel on behalf of the AAG to Beijing and Harbin, China, where I will be hosted by the Geographical Society of China to present in a session on “Scientific Organization Governance” at the China Association of Science and Technology Meeting, and will present academic talks on my team’s Ancient Water Management research, at Chinese universities. It is a privilege to be able to collaborate internationally, and to thereby conduct science and science diplomacy. Getting back to my yearlong theme of Science, Geography, and Human Rights, we must strive to fulfil the ideals of making science accessible to the benefit of all people; of guaranteeing scientists their rights to practice and to preserve science; and to protect scientists’ rights to collaborate freely and internationally.
Although my title will change to Past President on 1 July, my service to AAG as a member of the leadership team will continue for one more year: on the AAG Executive Committee, the AAG Council, and the Disciplinary Matters Committee. My writing assignment will shift from a monthly column, to composing the content and form of the Past Presidential Address for the Denver meetings and for the Annals, as per tradition. I look forward to my new role, and continuing to serve our association. I congratulate the incoming President, David Kaplan, and thank him for his service this past year as Vice President, and ask that you all lend your support to his efforts and themes. I also thank Derek Alderman for his service as Past President, and congratulate him on completing his term on the AAG Council, concluding on 30 June. I also extend a warm welcome and best wishes to Vice-President elect Amy Lobben. Speaking of service, please do not forget to nominate deserving AAG members for awards! See the AAG website for complete details.
The AAG Council and AAG Committees and Task Forces deserve much of our thanks for keeping our association vibrant and dynamic through their volunteer efforts. I am most grateful for the lasting friendships and professional relationships that have been formed with the Officers, Council, Committees, and the AAG Staff, and thank them all for their support during my presidency and beyond. My final words of praise are for the AAG Staff, the Legal team, and retiring Executive Director Dr. Douglas Richardson, for their day in and day out dedication to this non-profit organization’s mission and members. I will not be able to name all of the AAG staff in this column but please know you are a terrific team! I will note that AAG’s Rebecca Pendergast and Emily Fekete are especially thanked for their good-natured patience with my stretching the concept of “column publication deadline.”
AAG Members, I thank all 12,000 of you for making the AAG a community. I look forward to seeing you at future meetings, especially in Denver for the 2020 AAG Annual Meetings. Make a Difference with Geography. Have a great summer, wherever your Geography takes you!
