Summary: Agricultural policies can indirectly impact the natural environment through their influence on farmer input behavior. This study examines the specific effects of crop insurance participation on nitrogen and phosphorus concentrations in waterways. The results suggest that higher crop insurance participation is associated with lower nitrogen concentrations but does not have a consistent effect on phosphorus concentrations.

Summary: Global agriculture trade has significant impacts on the environmental sustainability of the world's food systems, but the exact nature of these impacts is still disputed. Trade can reduce the environmental impact of food production by moving production to places with more resources, but it can also limit the effectiveness of domestic environmental policy. Consumers are leveraging trade policy to induce exporters to improve environmental sustainability, but such measures may require support from decision makers in countries where environmental damages occur.

Summary: This article points out that many of the barriers to progress in addressing environmental problems, such as climate change, are political. The article argues that politics should be seen as a target of intervention to advance environmental solutions, rather than just a constraint. Using the example of climate change, the article illustrates how insight into politics can help policymakers craft strategies to address the ambition gap, the implementation gap, and the international action gap.

Summary: The agricultural-economic model proposed in the article explores subjective yield probability distributions that are better suited to subjective crop yields, allowing for analysis of the impact of changes in fertilizer price and expected yield variance. The model results suggest that the rule of fertilizing for good years is rational and consistent with expected profit maximization under yield uncertainty.

Summary: Reducing ammonia (NH3) volatilization from intensive cropping systems is essential for preventing pollution and ensuring sustainable agriculture. This study calibrated and evaluated the DNDC model using a two-year field experiment to simulate NH3 volatilization and crop production in a rice-wheat rotation system under different fertilizer treatments. The results showed that the calibrated DNDC model effectively simulated NH3 volatilization and grain yields for both crops. The sensitivity analysis revealed that N application rate greatly influenced NH3 volatilization, and the mixed application of inorganic and organic fertilizer significantly mitigated NH3 volatilization and improved crop yields.

Summary: Local governments in China face challenges in achieving environmental control amidst economic policy uncertainty, particularly in the mining, non-fuel minerals, energy minerals, fossil fuels, or metals industries. A positive correlation is found between economic policy uncertainty (EPU) and pollution, with each unit increase in EPU associated with a decrease in wastewater and exhaust emissions. Furthermore, EPU reduces investment but encourages innovation, particularly in green technologies, in these industries.

Summary: Currently, the inadequate supply of land resources is seriously impeding the sustainable development of the regional economy. Improving urban green land use efficiency has become a key issue for sustainable development. This study measures the urban green land use efficiency of 107 cities in the Yangtze River Economic Belt using the Global Malmquist-Luenberger Index, and empirically analyzes the effects of industrial specialization agglomeration and diversification agglomeration on this efficiency using a dynamic panel model. The results show that the efficiency is generally decreasing, and different modes of industrial agglomeration have varying impacts on the efficiency.

Summary: Nitrogen is a crucial input for food production, but a significant amount of nitrogen fertilizer is wasted and contributes to environmental pollution. By 2050, nitrogen pollution levels are expected to rise significantly, with agriculture playing a major role in this increase. Addressing nitrogen pollution requires collaborative efforts from policymakers, farmers, and researchers.

Summary: With climate change worsening, policymakers should enforce environmental regulations to encourage firms to adopt sustainable corporate models. The study shows that the EU Emission Trading Scheme can activate the Porter hypothesis and promote the implementation of sustainable corporate models by firms. However, the economic crisis can neutralize the effects of environmental regulations on firm performance, preventing the triggering of the Porter hypothesis in severely affected firms.

Summary: This study compared dynamic and static nitrogen fertilizer recommendation tools, finding that increasing accuracy in EONR predictions with dynamic tools does not necessarily lead to higher profits. Both tools have the potential to reduce nitrogen leaching, with dynamic tools being more accurate overall and static tools achieving similar results by recommending slightly higher N rates.

Summary: Transparent, consistent, and statistically reliable land use/land cover area estimates are crucial for assessing land use change and greenhouse gas emissions. This paper reviews six commonly used data sources and two remote sensing-based data products to investigate land use/land cover and change in the contiguous U.S. The study identifies research gaps and challenges in current land use studies and suggests opportunities and emerging techniques for improving reliability. Blended approaches that combine high-quality ground truth data with multitemporal imagery are needed to track non-agricultural lands vulnerable to agricultural expansion.

Summary: This study investigates the potential relationships between nitrogen management and soil health indicators (SHI) in an on-farm experiment in central Illinois. The results show that maize yield and nitrogen losses are related to different SHI and vary by sampling time. Total soil carbon and permanganate oxidizable carbon (POXC) are key factors explaining yield variation, while POXC and sand content explain variation in nitrate-N loss. Nematode indices also have the potential to serve as soil health indicators. This study provides a foundation for further research on the linkages between SHI, nutrient losses, and crop productivity.
