Special Issue Information

Dear Colleagues,

Over the past 15 years, many papers have studied the economic and environmental impacts of biofuel production and policy. In this area of research, a large number of papers have studied the extent to which biofuel production and policy may Induce Land Use Changes (ILUC) around the world. These papers considered a wide range of topics from theory to applied modeling practices and identified those factors that may significantly affect land use changes due to biofuels and their corresponding greenhouse gas (GHG) emissions. While from a theoretical point of view, several papers have shown that various market-mediated responses and biophysical conditions are the main factors that affect land use emissions due to biofuels, the numerical assessments of these effects vary significantly across the literature. These numerical assessments have been mainly obtained from modeling practices that follow different approaches, use diverse economic and biophysical data, and rely on various assumptions. While the validation of these estimates is a challenging task, one could develop analyses to indirectly evaluate the extent to which the estimated ILUC emissions are realistic. This could be accomplished via various testing and verification methods.

This Special Issue aims at developing these testing and verification methods. Validating technological progress in agricultural activities and changes in crop yields, observing land use changes and associated carbon implications in countries that produce biofuels and elsewhere, studying changes in crop prices and their drivers over time, examining changes in trade pattern of crops and food products, and assessing changes in the consumption of food products around the world are important verification approaches. These approaches could also capture sustainability of biofuel production. Examining the implemented data, assumptions, and approaches that were used in estimating ILUC emissions are additional items that can be used in assessing the estimated IULC values. 

This Special Issue welcomes original research articles and reviews that address the above topics.

We look forward to receiving your contributions.

Understanding changes to soil organic carbon storage (SOC) requires knowledge of detailed land use history. Many satellite-based analyses of land use change have been conducted over short periods (typically 5 to 10 years) to investigate causality to a demand increase in an agricultural commodity. However, statistically significant changes in SOC are not readily observable during this time and typically require decades for meaningful differences to accrue. This study aimed to determine land use and soil organic carbon stocks on land parcels over 36 years (1985–2021) located in areas where historical land use transitions between cropland and non-cropland are prevalent. Aerial and satellite imagery were analyzed across 25,992 hectares in ten counties across the Corn Belt. Grower interviews were conducted to solicit feedback on the drivers of land use change. Finally, SOC analyses associated with land use changes were determined using two process-based models. Analysis showed that 371 of the parcels had remained in cropland, 611 parcels transitioned into non-cropland, and 18 parcels were identified as non-cropland. The grower surveys indicated that the most common reasons for returning land to crop was the difficulty getting land re-enrolled in the CRP and reduced cattle prices. Both the SALUS and GREET-CCLUB models were parameterized to assess soil carbon changes for the respective land use history, and both models returned consistent SOC increases at the county level over time.
