An agronomic-economic approach to connect manure nutrients back to grain-producing regions.

Stakeholders for nutrient-impaired watersheds have long discussed the causes and consequences of nutrient surpluses associated with intensive livestock production. Nonetheless, nutrient surpluses relative to crop requirement, particularly with phosphorus (P), persist and continue to contribute to water quality impairment. Nutrient life-cycle analysis shows that mineral P, from soil minerals or mined fertilizer P, flows to livestock regions from grain-producing regions.

Public preferences for ecosystem services on exurban landscapes: A case study from the Mid-Atlantic, USA.

This paper reports data from a residential landscape preference study conducted in Delaware, USA. The researchers constructed an ecologically designed exurban residential landscape, which delivered 20 new environmental and human-related impacts, including 7 that delivered ecosystem services. Ecosystem services included impacts such as improved flood control and enhanced plant diversity.

Capitalization and proximity to agricultural and natural lands: evidence from Delaware.

This paper offers an applied study assessing the price impacts of proximity to open space in a residential property market. Data are collected in an urban-influenced region of Delaware, USA, which has experienced rapid population growth--an 85 percent increase in number of households and 92 percent increase in population between Census 1990 and Census 2000--but also maintains substantial agricultural land use. In agreement with previous literature the results show the protection of agricultural and natural lands is capitalized into the value of neighboring properties.
