Methane from livestock manure accounts for 6.6% of total greenhouse gas (GHG) emissions in the United States, and 1.1% of total emissions in Canada. Methane is 25 times more potent than CO2 as a GHG and is emitted into the atmosphere from enteric emissions and manure. Livestock operators can reduce CH4 emissions and may qualify for credits for its capture by utilizing manure management practices such as anaerobic digesters. Thus, livestock producers can play a role in reducing GHG emissions while also earning C offset credits. This paper has two related objectives. First, using data from Canada, we explore the …

With the potential expansion of forest conservation programs spurred by climate-change agreements, there is a need to measure the extent to which such programs achieve their intended results. Conventional methods for evaluating conservation impact tend to be biased because they do not compare like areas nor do they account for spatial relations. We assess the effect of a conservation initiative that combined designation of protected areas with payments for environmental services to conserve overwintering habitat for the monarch butterfly (Danaus plexippus) in Mexico us a spatial-matching estimator which matches covariates among polygons and their neighbors, to. We measured avoided forest …
