  • The Study Team will make and define a series of assumptions about future land use, urban development, climate, geomorphic processes, the agricultural drainage system, and watershed management in the MRB. These assumptions will be used as input variables in the model system to simulate future (some specified year, e.g., 2025) conditions. The small watershed, large watershed, and river water quality model systems will be used to simulate future (without projects or change in management) conditions of system hydrology, loading rates, and Minnesota River water quality conditions.

  • In his History of the World Roberts (1990:908), commenting on a world population exceeding 5 billion persons, writes: ‘Though it had taken at least 50000 years for Homo sapiens to increase to 1000 millions (a figure reached in 1840 or so) the last 1000 million of his species took only 15 years to be added to a total growing more and more rapidly’. More recently it is estimated that the world population reached 6 billion in October 1999 and that the increase from 5 to 6 billion, huge army of the world’s desires, took place in a mere 12 years (Schoon 1999)....

  • In many settings nitrogen enrichment of surface water bodies has increased following the increased use of N fertilizers. The precise contribution of nitrogen fertilizers to surface water nitrogen has been difficult to quantify because there are multiple sources of nitrogen contributing to most water bodies, and, depending on environmental conditions, a certain portion of soil nitrogen may be converted to gaseous or immobile forms.

  • On schemes involving different types of engineering, design may be let out in separate ‘packages’ to different specialist consultants. For instance the design of an industrial estate may be packaged into – roads and drainage; water supply and sewerage; power supplies, and landscaping. For large schemes the promoter may appoint an overall consultant with wide experience to co-ordinate the inputs of the specialist design consultants.

  • Human health can be affected by acute or chronic exposure to toxicants, through the media of water, wet land sediments, or even air when sediments becom dessicated and airborne or burnt. The nature of thes exposures is exacerbated by human behaviours and activities and they can result whenever ecosystem services have been eroded – especially when the hydrological services that maintain biological, geo logical and chemical processes have been distorted by human activities of over extraction of water.

  • Indicators reveal children are somewhat better off in urban areas than their rural counterparts. However, analysis of data show a growing “urban penalty” related to numbers of the urban poor and deteriorating conditions. Malnutrition is also becoming more of an urban problem, related to higher food costs, reliance on a cash economy and unsanitary conditions.116 The urban poor live in informal settlements without the secure tenure that protects them from eviction. The lack of a legal address can also mean disenfranchisement and difficulty to access services (e.g.
