Urban water-treatment costs depend on the water quality at the city’s source, which in turn depends on the land use in the source watersheds. Here, we show that globally urban source watershed degradation is widespread, with 9 in 10 cities losing significant amounts of natural land cover in their source watersheds to agriculture and development.
Cropland maintains a premium over pastureland due to mostly higher per-acre returns to crop production. The difference between cropland and pastureland values also vary by region.
The actual 2018 usda estimates of value per acre for nebraska irrigated cropland is $6,150/acre while non-irrigated cropland is $3,550/acre. Over the near term, it is likely that the most significant structural variable affecting cap rates and ultimately farmland values is the risk-free rate as measured by 10-year treasury yields.
In addition to the state-wide averages, the map below shows the estimated cropland prices for most townships across wisconsin. Those values are based on a statistical hierarchical spatial model 4 which analyzed 8931 transactions between 2009 and 2019 to estimate agricultural land values in wisconsin across space and time.
The most comprehensive product currently available to estimate management parameters is the census of agriculture (statistics canada 2004).

Urban sprawl (also known as suburban sprawl or urban encroachment) is the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning.
The cropland practices of fertilizer substitution, crop straw and conservation tillage are beneficial and help to rebuild local soil carbon stocks and reduce soil carbon emissions, in addition to reducing the consumption of fertilizers and fossil fuels. These improved cropland practices can directly and indirectly mitigate carbon emissions.

Estimates of cropland, urban area, rural transportation and rural parks/wilderness areas, which are based largely on census data and administrative data, are developed first. The estimates of forest-use land and pasture/range are then developed, followed by ‘other’ land uses.

Nations’ food consumption patterns are increasingly globalized and trade dependent. Water, pollinators) are hence being virtually exchanged across countries. Inspired by the virtual water concept, we, herein, propose the concept of virtual biotic pollination flow as an indicator of countries’ mutual dependence on biodiversity-based ecosystem.

When estimating c stocks and emissions, we assumed that the pre-conversion landcover of a converted pixel was that reported by the cdl in the year prior to conversion and we omitted pixels where the pre-conversion landcover was identified as surface water, ice/snow, development or barren due to the ambiguity of their pre-conversion c stock.
Cropland expansion occurred across most of northeast china, while cropland shrinking occurred only in the northern and eastern sections of northeast china and around the capital cities, in the flat areas. Also, changes in land use away from cropland mainly occurred in areas with low elevation (50–200 m) and a gentle slope (less than 1 degree).
Some of the most important factors that go into determining the right site are: property size; visibility; traffic flow; demographics; zoning restrictions; surrounding.
Global cropland net primary production has tripled over the last 50 years. However, long-term comparisons across global croplands are scarce due to the lack of detailed management data. Here, we conducted a simulation study of global cropland production from 1961 to 2010 using the vegas model.
Dec 28, 2015 on the basis of 495 site-years of measurements at 78 sites across chinese croplands, we developed a nonlinear bayesian tree regression.
Development on farmland can have negative effects, removing land that animals use as a habitat. Well-operated farms care for the soil, air, and water, and produce viable ecosystems. Economically, the agricultural industry employs millions in all sorts of fields, from machinery to inputs to researchers to retailers to packagers.
