Buddhism is a vast and heterogeneous set of traditions embedded in many different environments over more than two millennia. Still, there have been some similar practices across Buddhist cultures that contributed to the construction of local Buddhist environments. These practices included innumerable stories placing prominent Buddhist figures, including the historical Buddha, in particular places. Many of these stories concerned the conversion of local serpent spirits, dragons, and other beings associated with a local place who then themselves became Buddhist and were said to protect Buddhism in their locales. Events in the stories as well as relics and landscape features were marked by pillars, reliquary shrines (stupas), caves, temples, or monasteries that often became the focus of pilgrimage or considered particularly auspicious places for Buddhist practice, where one could encounter buddhas and bodhisattvas. Through ritual practices such as pilgrimage, circumambulation, and offerings, Buddhists engaged environments and their local spirits. Landscapes were transformed into Buddhist sites that were mapped and made meaningful according to Buddhist stories and cosmology. Farmers, herders, traders, and others in Buddhist cultures whose livelihood depended on their environments engaged the spirits of the land, whose blessings they needed for their own good.
Just as they transformed the meaning of local environments, Buddhists also transformed the material environment. In addition to building monasteries, stupas, and other religious structures, Buddhist monastics developed administrative and engineering expertise that enabled large-scale irrigation systems. As Buddhism spread through Asia, it brought agricultural technologies that created the watery landscapes enabling rice production and increasing the agricultural surplus that made possible large monasteries and urbanization.
In the last decades of the 20th century and the first decades of the 21st, eco-Buddhist scholars and practitioners have found resources in Buddhist traditions to construct a Buddhist environmental ethic. Some have argued that concepts such as dependent origination, the ethics of loving-kindness and compassion, and other ideas from classical Buddhist traditions suggest that Buddhism has always been particularly attuned to the environment. Critics have charged that eco-Buddhists are distorting Buddhist traditions by claiming that premodern traditions were responding to contemporary environmental concerns. Moreover, they argue, Buddhist ideas such as dependent origination, or its more environmentally resonant interpretation as “interdependence,” do not in fact provide a satisfying grounding for an environmental ethic. Partly in response to such critics, much scholarly work on Buddhism and the environment became more focused on concrete phenomena, informed by a variety of disciplines, including anthropology, archaeology, place studies, art history, pilgrimage studies, and the study of activism. Instead of focusing primarily on universal concepts found in ancient texts, scholars are just as likely to look at how local communities have drawn on Buddhist ontology, ethics, cosmology, symbolism, and rituals to develop Buddhist responses to local environmental needs, developing contemporary Buddhist environmentalisms.
