Raw materials for animal feeding are highly deficient in Europe, which results in massive imports of soya beans from North and South America. These imports are connected with a number of environmental problems. Increasing the grain legume production in Europe could be a promising alternative. The impacts of introducing grain legumes into existing European crop rotations are investigated in this article. The environmental impacts are evaluated by using the SALCA (Swiss Agricultural Life Cycle Assessment) life cycle assessment method and the ecoinvent life cycle inventory database.
Environmental and visual impact analysis of viticulture and olive tree cultivation in the province of Siena (Italy)
This study aimed at setting up a comprehensive approach on viticultural and olive tree cultivation environmental impact, through soil and landscape change analysis at the years 1965, 1990, 1994 and 2000, both at the catchment and province scales. The study area was the province of Siena, in central Italy. Following a DPSIR approach, the State indicators checked the Impact of agricultural policies (Drivers), which have increased the Pressure of specialized crops, and suggested Response actions.
What does it take to get family forest owners to enroll in a forest stewardship-type program
We estimated the probability of enrollment and factors influencing participation in a forest stewardship-type program, Minnesota's Sustainable Forest Incentives Act, using data from a mail survey of over 1000 randomly-selected Minnesota family forest owners. Of the 15 variables tested, only five were significant predictors of a landowner's interest in enrolling in the program: compensation amount, intention to obtain a forest management plan, opposition to the program's land covenant, prior awareness of the program, and total acres of forest land owned.
Molecular and functional responses of soil microbial communities under grassland restoration
The influence of ageing grassland on microbial community structure in different long-term grassland regimes compared to tillage in neighbouring fields was investigated to evaluate whether grassland restoration can be considered as a specific type of management for soil conservation in northern France. Microbial community structure was examined by analyzing the distribution of total and labile organic matter, the size of bacterial and fungal populations, and bacterial metabolic fingerprints and fungal genetic fingerprints.
Human behavioral impact on nitrogen flow--A case study of the rural areas of the middle and lower reaches of the Changjiang River, China
To assess sustainability of rural management in the Changjiang River basin, human behavioral (food consumption, lifestyle pattern, and human waste disposal) impact on nitrogen flow was quantitatively evaluated. A survey of day-to-day activities was conducted in two representative counties: Taoyuan and Taihe. Daily nitrogen intake from food per capita and potential nitrogen load from human waste on the environment were calculated. The former in Taoyuan and Taihe was 17.0 and 16.0gN, respectively.
