A data science and historical global political ecology perspective on the financial system, agriculture and climate: from the trans-Atlantic slave trade to agroecology

We show that narrative visualisation can contribute to identifying financial, legal, political, trade and other mechanisms capable of serving the diverse needs of practitioners of agroecology (primarily small scale farmers) and advocates of food sovereignty. Using financial and non-financial public information (re)sources such as historical macroeconomic data from the Bank of England and open source software tools, we paint portraits of (a) the trans-Atlantic slave trade and European Empires, (b) 21st century large-scale land acquisitions, and (c) traditional farming systems, agricultural biodiversity, and climate change. This triptych of background notes plus autonomous yet complementary cartograms and timelines overlaid with events provides long historical and large geographical lenses for understanding how the web of institutional and social structures of the United Kingdom, Europe, and the United States of America were and remain central to the international political ecology of agriculture, particularly food and fibre. We propose that policies that support, strengthen and scale agroecology can increase financial stability by reducing climate change-related physical, liability and transition risks thereby making macroeconomies more resilient to crises and prepared for adverse shocks. This exploration of human and natural systems affords also a window on the emerging fields of structural one health and planetary health Keywords: Economic policy; agricultural policy; alternative data; Bank of England; trans-Atlantic slave trade; British Empire; Large-scale land acquisitions; Traditional farming systems; agricultural biodiversity; agroecology; Community-led London Plan; Visualisatio
