Summary: This study systematically reviewed the impact of climate change on major staple crop yields in West Africa and analyzed the potential of common agricultural adaptation strategies. The results showed that crop yields declined by a median of 6% due to climate change in all scenarios analyzed. However, by adopting adaptation strategies such as optimized planting dates and resilient crop varieties, crop yields affected by climate change could be increased by 13%. Increased fertilizer use did not mitigate the impact of climate change on crops but could substantially increase yields. The study suggests that a combination of increased fertilizer use and adopting cropping practices that take advantage of favorable climate conditions has great potential to protect and enhance future crop production in West Africa.

Summary: Coral reefs and associated fish populations are at risk of extinction by the end of the century without additional long-term strategic conservation efforts. This study examines public willingness to pay for global coral and reef fish conservation in 12 countries of varying income and tropical reef proximity. The findings suggest that public preferences are not aligned with effective conservation measures, with individuals being more willing to act when reefs are in serious decline and preferring hands-on restoration measures over other approaches. Conservation demand is highest in countries with lower income. These results have important implications for policymaking decisions.

Summary: Climate change has resulted in disruptions to food systems, with a particularly alarming impact on global nutrition due to decreased grain production and reduced protein content and quality. This study examines the effects of temperature on barley growth and yield at different stages in four different climate areas. The research findings highlight variations in growth parameters, yield levels, soil composition, and mineral content between the group areas. The study concludes that certain areas are still not suitable for barley cultivation despite climate change.

Summary: Maize and soy production in the US has increased rapidly, reducing crop-damaging high temperatures. Agricultural intensification has created a crop-climate feedback, where increased crop production cools the local climate and benefits crop yields. The increased production of maize and soy has reduced warming effects and boosted crop yields, but a stagnation in production could expose crops to more harmful heat extremes.

Summary: Simulations of crop yield under climate change show significant variations depending on models, locations, species, management strategies, and Representative Concentration Pathways. A meta-model based on site-level simulations was developed to understand the effects of climate and adaptation on yield change for maize, rice, wheat, and soybean. The study found that adaptation plays a crucial role in mitigating projected yield losses under the RCP4.5 scenario, with most influential factors being adaptation strategy and climate change. These results highlight the importance of implementing adequate adaptation strategies to mitigate the impact of climate change on crop yields.

Summary: Climate change can directly and indirectly affect plant reproductive success through disruptions in animal pollination. Plants have evolved reproductive strategies to overcome limitations in pollen and water availability, and climate change may cause plants to become more pollen limited in wetter seasons. In this study, two perennial species showed different reproductive responses to future climate conditions, with one species producing more seeds when given supplemental pollen. The findings highlight the potential for changes in pollinator services to impact plant reproduction in a changing climate.

Summary: This study analyzes the effects of warming and soil water conditions on interactions between the tropical plant species Stylosanthes capitata and its floral visitors. Results show that warming treatments cause earlier flower opening and shorter duration, as well as an increase in sugar concentration in the nectar. Additionally, the relationships between S. capitata and bees and butterflies were affected by the warming conditions, and the combined effects of warming and water deficiency decreased insect visiting frequency around noon.

Summary: The aim of the study is to analyze the expectations of crop insurance system participants and to reveal the reasons for encouraging/discouraging farms in insuring their crops in Lithuania. The manufacture of agriculture production products is the most sensitive to meteorological conditions, with risks such as winterkill, hail, storms, and droughts. While additional means (optimization of crop structure, changes in growing technologies) can reduce the reliable harm of extreme climate change, it is only technical, organizational means (crop insurance) that can mostly reduce the loss of production.

Summary: Climate change is expected to affect insect pests and pollinators in agricultural systems worldwide, causing shifts in geographic ranges, population abundance, and interactions with other species. These effects are complex and variable, sometimes increasing pest pressure or reducing pollination, depending on climatic conditions and other contributing factors. In addition, climate change is driving changes in cropping systems that can further affect pests and pollinators. Effective pest and pollinator management strategies must consider this uncertainty and be integrated into agricultural production under climate change.
