A new book features two chapters on reducing agricultural greenhouse gas emissions penned by researchers at the Nicholas Institute for Environmental Policy Solutions—Brian Murray and Lydia Olander. The 456-page book reviews the state of agricultural climate mitigation globally and focuses on the design and implementation of activities to reduce emissions and increase carbon storage.

Climate change could substantially alter the width of beaches in Southern California. Climate-driven sea level rise will have at least two important impacts on beaches: (1) higher sea level will cause all beaches to become more narrow, all things being held constant, and (2) sea level rise may affect patterns of beach erosion and accretion when severe storms combine with higher high tides. To understand the potential economic impacts of these two outcomes, this study examined the physical and economic effects of permanent beach loss caused by inundation due to sea level rise of one meter and of erosion and accretion caused by a single, extremely stormy year (using a model of beach change based on the wave climate conditions of the El Niño year of 1982/1983.)

Ecosystem services play a crucial role in sustaining human well-being and economic viability. People benefit substantially from the delivery of ecosystem services, for which substitutes usually are costly or unavailable. Climate change will substantially alter or eliminate certain ecosystem services in the future. To better understand the consequences of climate change and to develop effective means of adapting to them, it is critical that we improve our understanding of the links between climate, ecosystem service production, and the economy. This study examines the impact of climate change on the terrestrial distribution and the subsequent production and value of two key ecosystem services in California: (1) carbon sequestration and (2) natural (i.e. non-irrigated) forage production for livestock.

Summary of discussion themes and guide to additional resources from the 2011 West Coast Fisheries Forum.

This report was prepared for the 2011 West Coast Forum on coastal and marine spatial planning. The first part explores the originals and drivers of CMSP, and the potential role that the regional councils might play in a CMSP framework. The second part explores opportunities for Councils to utilize existing authorities and mechanisms to coordinate with other ocean users.

A number of on-farm management practices can help to reduce U.S. agricultural greenhouse gas emissions and generate significant increases in carbon sequestration. This brief summarizes the mitigation potential and the state of scientific knowledge for a wide range of agricultural practices in the United States and highlights key issues for implementing programs to incentivize GHG mitigation in agriculture.

When development pressures transform mangroves, seagrass, and coastal wetlands, carbon stored in their biomass and soil is released to the atmosphere as carbon dioxide. One way to counter these pressures and thereby conserve the carbon stored in these habitats (referred to as “blue carbon”) is to provide payments for the environmental services they provide. This paper analyzes current and potential options for carbon mitigation payments as a source of blue carbon finance. With other work that has focused on the payments needed to secure blue carbon, this paper can help stakeholders assess funding gaps and direct scarce resources to those activities that will provide the greatest blue carbon benefits.

Approximately 6% of greenhouse gas emissions in the United States come from agriculture. This number could be reduced through the use of on-farm management practices, such as switching to no-till, reducing fallow, managing species composition on grazing lands, and adjusting management of nitrogen fertilizer. Efforts are under way by government, industry, and others to incentivize such practices by creating new business opportunities or revenue for farmers and ranchers. This assessment reviews a wide range of agricultural practices and provides a roadmap and resource for programs and initiatives that are designing protocols, metrics, or incentives to engage farmers and ranchers in large-scale efforts to enhance GHG mitigation on working agricultural land in the United States.

Agriculture is among the world’s largest sources of greenhouse emissions and is the largest source of certain types of anthropogenic nitrogen pollution. But as a source of renewable fuels production and carbon sequestration, agriculture could also be part of the solution to energy security and climate change problems. Similarly, improved management of agricultural nitrogen use could be the key to managing nitrogen pollution in surface- and groundwater systems. If policy makers are to determine how best to develop and implement effective policy interventions to correct environmental problems in agriculture, the critical linkages among demand, supply, land use, nitrogen use, and greenhouse gas emissions must be captured. This paper projects greenhouse gas emissions and nitrogen use from agricultural and forestry practices under baseline and alternative biofuel scenarios in the United States, while accounting for land use competition, production heterogeneity, and a full suite of biofuel production possibilities.

Climate change is expected to pose a number of risks to communities, such as sea-level rise and an increase in storm surges. States are beginning to develop adaptation plans to reduce climate risks and vulnerabilities within the larger context of economic growth. While the process and structure of the planning efforts vary, the resulting recommendations reveal similarities. The plans include a mix of broad strategies that address the state’s objectives and goals and identify supporting policies. To ensure complementary and coordinated responses to climate change, many strategies are cross-sectoral and entail integration and collaboration among multiple government agencies and economic sectors.
