In this study, emergy evaluation was used to analyze the Peruvian ecological – economic system. The material and energy flows were evaluated in units of solar emergy. The performance of the Peruvian system was assessed through emergy-based indices. The main calculated indicators are the following: (a) Emergy/USD ratio = 1.01 E+13 sej/dollar; (b) Emergy Yield Ratio (EYR) = 9.69; and (c) Environm...

Protected area (PA) is an indicator linked to policies on ecological sustainability. We analyzed area, size, and categories of PAs in the European boreal forest biome in Norway, Sweden, Finland, and Russia from 1900 to 2010. The PA increased from 1.5 × 10(3) ha in 1909 to 2.3 × 10(7) ha in 2010. While the total PA in the boreal biome was 10.8 %, the figures ranged from 17.2 % in the northern, 7...

Large-lot exurban landscapes could incorporate ecological design in order to contribute ecosystem services. In our study, we use a survey of 126 Southeast Michigan homeowners to examine respondents’ stated preferences for residential yard images, and compare those with reported current use and management of their actual yards. We found that stated preferences are not necessarily related to actu...
