Current and Emerging Protocols for Carbon Measurement in Agricultural Soils

Suraj Melkani, Noel Manirakiza, Shirley M. Baker, and Jehangir H. Bhadha

Soils have the capacity to function as a sink of atmospheric carbon dioxide and are crucial for climate regulation. Soil have the potential to store around 1.5 to 2.4 trillion metric tons of C in the soil globally. They contain large C pools that can store three times more C than the atmosphere and four times more than plants. These massive C sinks have the potential to reverse soil degradation, mitigate climate change, and enhance food security. It is therefore essential to monitor the C cycle by accurately measuring the amount of soil C in agricultural fields. This can help in developing sustainable management practices that can minimize C emissions and sequester C into the soil from the atmosphere. This publication describes the various current and emerging protocols that can be used to measure soil C.

Living Shoreline Ecosystem Service Valuation Tool

Ashley R. Smyth, Laura K. Reynolds, Savanna C. Barry, Natalie C. Stephens, Joshua T. Patterson, and Edward V. Camp

Living shorelines are an increasingly popular way to protect and stabilize waterfronts for coastal property owners. Living shorelines provide valuable benefits to humans, including water quality improvement, habitat, fisheries, and carbon sequestration. Estimating the economic value of the ecosystem services living shorelines offer is an integral part of management decisions. The living shoreline valuation tool can help quantify the costs and benefits of living shorelines projects. This publication briefly describes the ecosystem services associated with living shorelines. The purpose of this publication is to introduce the ecosystem service valuation tool. Our target audience for the living shoreline evaluation tool includes natural resource extension agents, community organizations, and coastal homeowners who want to calculate the value of ecosystem services provided by coastal restoration projects, including living shorelines.
