1. An approach to maintaining hydrological networks in the face of land use change

Author

Cuthbert, Andrew and Tyler, Mary-Ellen

Abstract

Ephemeral drainage patterns in the prairie pothole region of southern Alberta are not well understood at the landscape level. Municipal land use planning generally places very few constraints on development, which can leave the existing landscape topography and drainage patterns highly modified and engineered. Few if any features that exist within the pre-development landscape remain post-development. Part of the residential or industrial land development process is the creation of master drainage plans which focus on collecting and moving precipitation or snow melt away from roads and buildings through drainage ponds and piping systems. However, in prairie pothole landscapes, there is a landscape hydrology system that connects wetlands and sub-surface soil moisture flows and involves significant ephemeral components. These existing landscape flow systems provide ecosystem services in both flood and drought conditions. However, conventional land conversion processes do not generally recognize existing landscape processes like hydraulic connectivity in the development process. This creates a gap between the standard engineering approach and landscape structure and function which puts landscape processes and services at risk of being lost over time. The method demonstrated in this paper has been designed to bridge pre-development and post-development conditions for hydrologic flow systems. This method can be used as an additional cross-scalar information “layer” for use in the planning process to identify how utilities, roads and building sites can be spatially organized to complement rather than conflict with existing landscape flow systems in areas with minimal topographic relief and specifically in Prairie Pothole Region landscapes. This relatively simple technique can help reduce infrastructure costs and enables development to maintain natural flow systems and cross-scalar hydraulic connectivity.

2. Managing Biosocial Systems in 2010.

Author

Tyler, Mary-Ellen

Abstract

In this article the author discusses aspects related to projected goal of biosocial systems or environmental management by 2010. She cites that the goal of environmental management in 2010 is to manage the synthesis of resilience, social learning, and integrative research. She notes that the management of the above synthesis will need the cooperation between academics and non-academics for a resilient biosocial systems framework. Studies related to environmental management are also mentioned.

3. Spiritual stewardship in aboriginal resource management systems

Author

Tyler, Mary Ellen

Abstract

Gitksan and Wet'suwet'en tribal groups in northwestern British Columbia are an example of aboriginal peoples involved in the practice of sacred or spiritual stewardship in their ancestral homelands. All aspects of tribal organization and function are infused with spiritual expression including the use of dreams, visions, teachings from the myths of oral tradition, and the symbolic representation of their tribal worldview (including both earthly and supernatural elements) in language, material culture, social and geographic organization, art, dance, and song. The practice of spiritual stewardship involves the ritual taking and use of natural resources according to cultural protocols established in tribal mythology and validated within a cosmology that views human beings as part of an interacting life force continuum that includes animals and spirit beings. Animals and fish are viewed as intelligent societies having the power to influence events and, as such, they must be treated with respect using instructions encoded in the myths and teachings of the people's oral tradition. In the context of this cosmological framework and its associated sacred geography, sociocultural resource management practices are based on a body of heuristic and phenomenological aboriginal knowledge. Spiritual stewardship represents a cosmic sanctioning of ethics that ensures the continued future supply of strategic life-supporting resources and thereby ensures the future of the people who depend on them for cultural and physical survival.
