We analyse CO2 emissions reduction costs based on project data from the Climate Cent Foundation (CCF), a climate policy instrument in Switzerland. We draw four conclusions. First, for the projects investigated, the CCF on average pays € 63/t. Due to the Kyoto Protocol, the CCF buys reductions until 2012 only. This cutoff increases reported per ton reduction costs, as the additional lifetime pro...

In this paper we develop methods to investigate the efficiency of alternative contracts for Carbon (C) sequestration in cropland soils, taking into account the spatial heterogeneity of agricultural production systems and the costs of implementing more efficient contracts. We describe contracts being proposed for implementation in the United States and other countries that would pay farmers for ...

In crop insurance design, the yield guarantee and the premium are very important parameters, both of which depend upon the yield distribution. Accordingly, the accurate modeling of yield distribution is essential for designing crop insurance contracts. This study employs historical county-level yield data for irrigated and dry wheat in East Azarbaijan Province, Iran for 1975-2013 to evaluate th...

The biogas supply chain requires a correct combination of crops to maximize the methane yield per hectare. Field trials were carried out in North Italy over three growing seasons, according factorial four cropping systems (maize as sole-crop or after hybrid barley, triticale and wheat) two maize plant densities (standard, 7.5 plants m−2 high, 10 m−2) with harvested whole-crop silage. specific p...

In order to study the effect of natural zeolite superabsorbent on yield and yield components of linseed under different moisture regimes, a split plot experiment was conducted in a randomized complete block design with 3 replications at Research Farm of Shahrekord University, Shahrekord, Iran in 2017. The main factor in four moisture regimes included irrigation after 50 (control), 80, 130 and 1...

This study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, pH value of gastrointestinal (GI) tract and small intestinal morphology of laying hens. The experiment was a completely randomized design with 160 laying hens strain (W-36) from 32 to 42 weeks of age, with five treatments, four replicates an...

Plant nutrition management is an important factor in the success of cultivation of medicinal plants, which leads to the improvement of their quantitative and qualitative yield. Therefore an experiment was conducted as a randomized complete block design with three replications and 8 nutritional treatments during three growing seasons on Satureja. spicigera Jamzad.The treatments were different le...

Hand-applied dispensers are successfully used in mating disruption programs, but cost of labor to apply these dispensers limits their adoption. Creating hand-applied dispensers that release larger amounts of pheromone and that can be applied at lower densities per hectare could reduce the cost of mating disruption and increase its use. The effect of reducing the number of point sources per hect...
