Summary: Multi-hybrid planting has the potential to reduce yield variation caused by soil, disease, and environmental factors. A research trial conducted in eastern Nebraska examined the placement of offensive and defensive maize hybrids based on soil type and water availability. Results showed that planting a single hybrid optimized economic return, although planting a defensive hybrid had no negative consequence in some fields and provided yield protection in dry years. Zone scenarios were created for each field to determine the optimal hybrid placement for each growing season.

Summary: Drought is a common abiotic stress that affects the growth and productivity of maize. In this study, 27 elite maize inbred lines were evaluated for their drought tolerance. The results showed that a large proportion of inbred lines selected from specific breeding populations demonstrated higher drought resistance and could be categorized as high-yield drought-resistant types. This study provides valuable insights for improving drought resistance and breeding new varieties of maize.

Summary: Agricultural producers relying on rangelands are vulnerable to weather-related risks. Index-based insurance products can help mitigate these risks, but residual risk remains. This study assesses basis risk and insurance contract quality for California rangelands.

Summary: This paper assesses the feasibility and robustness of an index-based insurance scheme against hydrological droughts under climate change. The study develops a grand ensemble that combines multiple models and scenarios to estimate the insurance risk premium, aiming to identify potential challenges and minimize regret in the design of the proposed scheme. The results indicate that the proposed insurance scheme is actuarially feasible and affordable under stationary climate scenarios, and mostly feasible under climate change scenarios, with some outliers suggesting potential challenges.

Summary: This study surveyed and analyzed the intention of German farmers to adopt drought insurance, finding that factors such as gender, risk attitude, land tenure, previous weather risk impacts, and trust in index insurance products have a significant impact on farmers' intention. The results are important for policymakers, insurers, and researchers focusing on farmer adaptation to climate change.

Summary: This study evaluates the impact of risk management tools on the agricultural performance of rural producers in Senegal, who benefit from the joint support of the Senegalese state and the International Fund for Agricultural Development (IFAD) through the co-financed project PADAER. Using data from two regions in Senegal, the study found that subscribing to index-based insurance facilitated by PADAER had a positive effect on the farmers' income by covering potential losses and generating additional gains. This study contributes to the understanding of the effects of agricultural index-based insurance in Africa using real-world statistical data.

Summary: This study contributes to a proof-of-concept comprehensive drought risk assessment for Vietnam by incorporating drought exposure and vulnerability based on specific socio-economic conditions of the regions, and using satellite data for drought hazard assessment. The highest at-risk provinces were identified in the Mekong River Delta, while the South East regions were less impacted by drought. The proposed approach has the potential to improve drought preparedness and resilience of communities at-risk.

Summary: The dynamic interplay between climate change and socioeconomic development has led to significant changes in drought hazard, vulnerability, and risk in the global socioeconomic system. However, there is a lack of understanding about how these changes will manifest in an increasingly globalized economy under global warming. A comprehensive study has utilized various data to map and assess changes in global drought vulnerability and risk in the future, finding that the future population at risk of drought is projected to increase driven by rapid population growth and substantial changes in drought hazard and vulnerability. The study highlights the need for targeted strategies and measures of adaptation and mitigation in the face of global warming.

Summary: Plant drought tolerance is determined by how the photosynthetic apparatus adapts to water deficit. This study analyzed the OJIP kinetics of seedlings from three Brassica crops under drought conditions to find parameters for distinguishing drought-tolerant and drought-sensitive varieties. The increase in PItotal, SFI, positive L and K bands, Delta DF, and DRI indicate drought tolerance, while negative L and K bands, PItotal, SFI, and RC/CS0 density can distinguish susceptible varieties. Kale was the most tolerant, Chinese cabbage was moderately susceptible, and white cabbage was highly sensitive to drought stress. The genetic variation among these crops could be utilized in breeding programs and crop management.

Summary: Droughts are causing severe damages to tropical countries worldwide. Little knowledge about tropical drought characteristics exists, calling for reliable methodologies to evaluate drought risk in data scarce tropical regions. This study combined drought hazard and vulnerability related data to assess drought risk in four rural tropical study regions, providing relevant information for regional planners and water managers dealing with future drought disasters.

Summary: Index insurance has been introduced as a solution to tackle challenges in agricultural insurance in developing countries. This study analyzes the accuracy of globally available satellite data in Uzbekistan, finding that while these sources may provide necessary data, there is a risk of overestimation and underestimation in precipitation data in Central Asia. Among the tested datasets, GSMaP shows relatively better performance in precipitation estimation for drought and flood detection.

Summary: This study investigates the feasibility of using satellite images and machine learning models to classify agricultural field parcels into those with and without crop loss. Despite the poor quality of data, the random forest model shows promising results in identifying new crop-loss fields based on reference fields of the same year. There is potential for various applications in efficient agricultural monitoring and verifying crop-loss claims.

Summary: Farmers value crop insurance under certain conditions and are willing to pay premiums higher than government-subsidised rates. They prioritize timely payouts and may not have a strong preference for the method of loss assessment. Farmers are sensitive to coverage periods.

Summary: Consumers are more accepting of gene-edited foods than transgenic modified foods, and the impact of information provision on consumer preferences differs between pork and rice products as well as on preferences for product provenance. Reducing consumers' fear of novel food technologies can substantially increase consumer valuation and market acceptance of bioengineered food products.

Summary: The study demonstrates that providing calibrated financial incentives can significantly increase the adoption rate and intensity of conservation agriculture (CA). Furthermore, leveraging social networks to consolidate fragmented land may be more effective in bringing more land under conservation objectives, even if some additional land is not officially under the PES program. The research also shows that perceived weaknesses hindering the adoption of CA may not be obstacles in specific study areas, suggesting that subsidies may only be needed to overcome short-term transition costs.

Summary: The growing prevalence of livestock in rural China poses a growing threat to wildlife and forest ecosystems. Achieving the goals of biodiversity conservation and rural development requires cooperation and coordination from local communities. However, little is known about the prevalence of social attitudes and the impact of cooperation and coordination in natural resource management.
