| This paper uses an economic catchment model to assess changes in land use, enterprise distribution, greenhouse gas emissions and nutrient loading levels from a series of policies that introduce carbon prices or nutrient reduction caps on land-based production in the Hurunui Catchment in Canterbury, New Zealand. At $20/tCO2e, net revenue for the catchment is reduced by 7% from baseline levels while GHGs are reduced by 3%. At $40/ tCO2e, net revenue is reduced by 15% while GHGs are reduced by 21%. Nitrogen and phosphorous loading levels within the catchment were also reduced when landowners face a carbon price, thus providing other benefits to the environment. Additional scenarios in this paper assess the impacts from developing a large-scale irrigation... |

| This paper uses responses from a regional farmer survey that identify farmers’ perceptions of environmental policies to calibrate a catchment-level environmental economic model (NZ-FARM) to estimate the impacts of a nutrient reduction policy in North Canterbury, New Zealand. The model maximizes farm income across a catchment, accounting for changes in land use, farm output, nutrient leaching, and GHG emissions. Simulations estimate that reducing nutrient loads by 15–30% can be achieved with economic impacts ranging between 1 and 10%, based on how willing landowners are to change how they manage their farm. Farmers are often hesitant to implement certain mitigation options, however, which results in higher economic costs than the ‘optimal’ estimates.... |

| Nutrient pollution, now the leading cause of water quality impairment in the United States, has had significant impact on the nation's waterways. Excessive nutrient pollution has been linked to habitat loss, fish kills, blooms of toxic algae, and hypoxia (oxygen depleted water). The hypoxic 'dead zone' in the Gulf of Mexico is one of the most striking illustrations of what can happen when too many nutrients from inland watersheds reach coastal areas. Despite the efforts of municipal building programs, industrial wastewater requirements and agricultural programs designed to reduce sediment loads in waterways, water quality and nutrient pollution continues to be a problem. We undertook a policy analysis to assess how the agricultural community could... |

| Bundled ecosystem markets may be the next big buzz in environmental policy and ecosystem conservation and restoration. But what does it mean? And what is the feasibility of these markets? While single service ecosystem markets are proliferating, bundled ecosystem markets are not. Using some ‘enabling’ and ‘operating’ conditions identified for various single ecosystem markets, I will see how these conditions hold as you move to bundled ecosystem markets. I also outline some of the hurdles that confront the development of bundled ecosystem markets and what may need to be reconciled to move these markets forward. This article is aimed at stimulating greater thinking and promoting more exploration by the policy and research community into the development of... |
