Production marginal land

Land-based biomass has a potential of providing from 7 to 1-1 quads/year of SNG if all available marginal land suitable for the growing of crops could be utilized. However, the doubtful availability of land and water for growing land-based biomass specifically for SNG production gives this supply option a lower priority than water-based biomass. The initial stage of the project concentrates on identifying natural species that will produce a maximum quantity of gas. 

As land price decreases, variable costs are unaffected but several fixed costs are reduced (e.g., management, interest and taxes on land). For tuber production, total annual costs fell from 3,798.95 (land price of 2,500-ha1) to 3,676.70, 3,570.75, and 3,501.48 for land prices of 1,750 ha-1, 1,100-ha-1, and 675-ha, respectively. For the production of tops in large bales, annual costs fell from 1,492.14 (land price of 2,500-ha-1) to 1,369.89, 1,276.14, and 1,194.67 for land prices of 1,750 ha-1, 1,100-ha-1, and 675-ha, respectively. Fand prices tend to be cheaper in western Canada and other areas of eastern Canada. For instance, at 1990 prices, land in the less fertile eastern townships was around 1,000-ha, while marginal land in the eastern townships was around 675 ha-1. Total annual costs for the production of tuber and tops in large bales in western Canada, where Jerusalem artichoke is likely to be grown in rotation with cereals, were 3,879.03 and 1,577.66, respectively, for a land price of 1,000-ha In eastern Canada, the total annual... 

How do EU agri-environment policies need to be framed in order for productive farmland to be converted in addition to marginal land ... 

In addition to enhanced unit productivity there may be some opportunities for expanded area contributions. ile expanding highly productive land area is unlikely due to competitive anthropogenic uses, there could be more development of marginal land areas for renewable resources. For example, the...
