    Climate Change Impacts on Crop Insurance

    Excerpt from the Executive Summary: In this report, we provide an assessment of the potential long-term implications of climate change on the U.S. crop insurance portfolio. Agricultural producers have always faced numerous production and price risks, but forecasts of more rapid changes in climatic conditions in the future have raised concerns that these risks will increase in the future relative to historical conditions. In addition to implications for landowner decisions regarding land use, crop mix, and production practices, changing agricultural risks could potentially affect the performance of the crop insurance program. Thus, we assess the potential implications of climate change on the financial returns to both the public Federal Crop Insurance Corporation (FCIC) and the private approved insurance providers (AIPs) under the current Standard Reinsurance Agreement (SRA) and identify potential considerations for the specification of the SRA and other aspects of the crop insurance program that may help to mitigate financial impacts

    Carbon sequestration and water management in Texas—One size does not fit all

    Abstract Climate‐smart agriculture (CSA) is an integrated approach to sustainably meeting food, fiber, and feed production needs. The technical and socioeconomic feasibility of different CSA strategies depends on local conditions, and there is no one‐size‐fits‐all approach. Here, we review two key aspects of CSA with a focus on Texas: soil C sequestration and water management. Carbon sequestration potential is highly variable across Texas as it depends on local biophysical conditions and soil management practices in place, for example, tillage and cover crops. Grasslands also have an important role to play in C sequestration. Important co‐benefits of effective soil management for C sequestration, such as reduced CO2 emissions, enhanced soil structure, and increased microbial activity, can positively impact soil fertility and productivity. The economic and political realities of C sequestration will have a strong influence on the implementation of technically feasible strategies. The major challenge for water management is the sustainable allocation of increasingly scarce resources. Expanded irrigation is a short‐term solution, but in many cases, the existing water supply is insufficient to meet future demand. A drying Texas, and aquifer depletion, portends lower future supplies. The Panhandle, Llano Estacado, and Rio Grande regions have the greatest projected gaps between future supply and demand. Increasing water‐use efficiency and using drought‐tolerant crops are important management goals and precision agriculture with site‐specific management measures could help improve drought resiliency. Texas’ geographic diversity is reflected in the variety of agricultural commodities produced by the state, and CSA activities are likely to be equally diverse

    Operating pesticide use reduction within the boundary of food security in peri-urban settings

    Pesticide use in peri-urban areas affects the urban environment and public health, and reducing the use may present food security issues for urban dwellers. In this study, we explore how a municipality-adopted goal of a 20% reduction in pesticide use could be achieved, along with local food security and environmental implications, for Shanghai located in the densely populated East China. A regional Shanghai Agricultural Sector Model incorporating district- and technology-varying crop budgets, was developed to simulate the effects of pesticide reduction policy. Here we find that achieving the reduction goal had the largest implications in districts with high pesticide use totals and intensities, potentially reducing pesticide non-point source pollution in the Yangtze River Estuary and Dianshan Lake; the production levels of rice and leafy vegetables would be most affected; and adopting machinery that allows more precise pesticide application modulates these results. Moreover, imposing the requirements at the district-level caused more severe local food security concerns, and less environmental benefits. Furthermore, a closed Shanghai's agricultural economy would substantially enlarge the regional heterogeneity in the above-mentioned outcomes. Exploring the effects of a quantity control policy on current-use pesticides at different aggregation levels has important implications for regulating the use of agrochemicals

    Impacts of Climate Change on Livestock Location in the US: A Statistical Analysis

    No full text
    Livestock production is a valuable part of US agriculture as it contributes 50% of total agricultural value. Climate change is likely a threat to livestock production, but research regarding the impact of climate change on livestock sectors is limited. This paper examines how climate change affects livestock mix and location. Specifically, we examine climate effects on grazing animals and, in particular, on beef cattle, dairy cattle, goats, and sheep. We examine this in the US based on county-level data by using fractional multinomial logit econometrics. Our results show that climate is an influential determinant of where livestock herds are located and species mix. The impacts of climate vary by species and region. We also find significant influences from geographic characteristics and animal product prices. Subsequently, we project how climate change would influence future livestock mix and location. It reveals a likely growth in beef cow land shares across most of the US with the largest gains in the northwest. We also find substitutions between species as climate change progresses with dairy cows exhibiting the largest reduction
