How Indigenous Knowledge Helps Manage Climate Change Effects On Human-Water Ecosystems

,

Outcomes of climate change on water include rising sea levels, warmer sea surface temperatures, and shifts in precipitation types, timing, and amounts. These outcomes have an impact on Indigenous Peoples’ relationship with water. Indigenous communities continue to draw from Traditional Ecological Knowledge (TEK) to maintain the overall vitality of human-water ecosystems in the context of climate change.

Sea surface temperatures have been increasing steadily throughout the 20th century and this trend continues. Changes in ocean temperature affect the ongoing presence of plants, fish life, and other animals. Increases in water temperature have also significantly altered the migration and breeding patterns of sea life, including shellfish. Another key impact is the presence and the frequency of the recurrence of “red tide,” a harmful algal bloom (HAB). Harmful algal blooms are toxic microscopic organisms (also known as cyanobacteria) that feed off the energy of light to grow; they are fatal to marine life, and can make humans sick.

The Southeast Alaska Tribal Ocean Research (SEATOR) network has been monitoring, sampling, and reporting on the levels of toxins among shellfish around the Alaskan Panhandle. SEATOR benefits from Indigenous Traditional Ecological Knowledge to help to predict harmful algal blooms (HAB), reduce poisoning, and harvest shellfish more effectively. Traditional harvesting practices of the Indigenous Peoples of Alaska help to keep Indigenous communities safe from the effects of HAB.

In another example of applying Indigenous Knowledge to manage human-water ecosystems, the Heiltsuk Nation (Bella Bella, British Columbia), on the West Coast of Canada, are applying traditional harvest practices, to facilitate the natural regeneration and resilience of kelp, at a small scale. With the assistance of researchers from the School of Resource and Environmental Management at Simon Fraser University, the Heiltsuk Nation are showing how their stewardship practices can help manage the growth of perennial kelp to make the kelp resilient to changes in the climate. University researchers were “motivated by the information needs” of the Heiltsuk Nation and together they co-designed a study to “measure the ecological resilience of feather boa kelp…and determine what environmental variables most affected its recovery.” The combination of Traditional Ecological Knowledge and Western scientific practices permitted the researchers to explore how the social relationship of the Heiltsuk Peoples to the ecological resilience of their environment are affected by increases in ocean temperatures.

Colonization compounds the effect of climate change (and vice-versa) on human-water ecosystem relationships. In Madagascar, for example, while rising sea levels have displaced Indigenous communities, conventionally, being nomadic, by choice, was also a way for Indigenous Peoples to deal with the unpredictability of the climate. However, a shift to sedentary lifestyles, further entrenched by modernization and colonization, have also affected human-water ecosystem relationships in Madagascar.

Drawing from a wide variety of Indigenous bodies of knowledge rooted in both Indigenous experiences and practices, shed light on different ways to manage climate change effects and to better understand the fine balance of human-water ecosystems in a changing climate.

Revitalizing Indigenous Oral Traditions to Enhance Climate Adaptation

,

Revitalizing all aspects of Indigenous oral cultures, including Indigenous languages, is necessary to enhance climate adaptation and to mitigate the loss of centuries of traditional Indigenous knowledge. Indigenous oral traditions are reflected in practices that transmit, receive, and protect Indigenous ideas, ways of knowing, art, and cultural materials, like songs and creation stories, from one generation to the next. Indigenous languages, as crucial contributors to Indigenous oral traditions, are constantly at risk of disappearing, due to ongoing colonization and climate-forced migration.

For example, South Pacific Islander oral traditions can “describe events that occurred as much as 400-700 years ago, less than one-third of the time that most western Pacific island groups have been occupied.” In turn, the Vanuatu government’s support for Indigenous language education in elementary schools could be viewed as an approach to both Indigenous language revitalization and climate change adaptation. Furthermore, to defend against language loss and to acknowledge modern environmental phenomena, Greenland’s government is legislating new words, such as ‘climate change’ (i.e., silap pissusiata allanngornera) among others, through Oqaasileriffik, their Language Secretariat, and is replacing dominant Danish place names for those in Greenlandic.

More than half of the 7,000 languages spoken in the world today will be lost within this century due to the ongoing effects of both colonization and climate change. Revitalizing Indigenous oral traditions and integrating Indigenous languages into local climate adaptation strategies are necessary to ensure the cultural and climate resilience of Indigenous peoples worldwide.
