Summary: The agricultural systems in northwest China are highly vulnerable to the impacts of climate change, with extreme climate disasters and increased pests and weeds posing significant challenges. In order to adapt and mitigate these impacts, key strategies include optimizing agricultural geographic distribution, cultivating new crop varieties, adjusting cropping practices, developing water-saving irrigation systems, enhancing disaster prevention and mitigation capabilities, and strengthening scientific and human resources.

Summary: By domesticating edible wild plants and utilizing advances in genomics and gene editing technologies, we can increase the stability of our food systems against environmental variability and climate change. Neodomestication allows for the rapid generation of new crops by selecting candidates based on climatic parameters, thus increasing food security. Conservation and characterization of edible species play a key role in this process, and the utilization of genetic resources should be carried out ethically and with benefit-sharing in mind.

Summary: Irrigated agriculture is crucial for global food production and adapting to climate change. Sustainable irrigation expansion provides opportunities to increase agricultural productivity, but also comes with external costs. Further research is needed to understand the implications and challenges of sustainable irrigation expansion.

Summary: Drought in the Pacific Island Countries and Territories (PICTs) is considered a creeping disaster as its impacts are usually not noticed until months or years after its onset. Monitoring, forecasting, and managing drought in the PICTs is complex due to the diverse ways in which droughts occur, as well as the varied direct and indirect causes and consequences of drought across the region.

Summary: Climate change has a significant impact on rice productivity in China, with varying effects among different cultivars. Replacing existing cultivars can only partly mitigate the yield loss caused by climate change in the future. Around 67% of single rice cultivation areas and 46% of double rice cultivation areas will require new cultivars before 2050. The mid-lower reaches of the Yangtze River have only two decades left for adaptation. The ideal traits for breeding cultivars to adapt to climate change include medium growth cycle, long grain-filling period, high photosynthetic capacity, and fewer spikelets.

Summary: Scientific evidence suggests that agriculture will be adversely affected by global climate change, particularly in South Asia. This study examines the economic impacts of climate change-induced agricultural productivity changes on Sri Lanka, using a computable general equilibrium model. The results show reductions in crop output, increased consumer prices, and a decline in household consumption, highlighting the need for research on climate change adaptation strategies and policy responses to mitigate adverse effects on agriculture and food security.

Summary: The study found a positive association between family type and adoption of climate-smart agricultural practices. Most rural households derive more than 50% of their daily per capita calorie and iron consumption from cereal crops. The Simpson food diversity index indicates that households adopting more practices consume more diversified food compared to those adopting fewer practices.

Summary: The study demonstrates that most farmers perceive adverse impacts of climate change on agricultural production, but their adaptation measures substantially increase rice yields, benefiting both adapters and non-adapters. Farmers' access to climate related information, education, membership in farmer organizations, and size of plots are found to play a key role in the adaptation process.

Summary: Climate change poses a challenge to global food supply chain security and long-term viability. This study focuses on the vulnerable food system of Saudi Arabia, which already faces stress due to climate unpredictability and extreme weather events. The findings highlight the positive causal relationship between GDP and food demand, indicating that an increase in GDP will lead to increased food demand in the long run. Additionally, the study shows that Saudi Arabia's GDP and population growth contribute to an increase in greenhouse gas emissions, emphasizing the need for appropriate policy approaches to ensure food security.

Summary: Record-breaking high temperatures in the summer of 2022 had significant impacts on the food system in the United Kingdom, including increased energy costs for cold storage, failures in refrigeration systems, and heat stress on livestock. Future climate projections suggest that such extreme high temperatures are likely to occur more frequently. Studying the effects of the 2022 heatwave can help identify adaptation strategies for building resilience in the face of climate change. Case studies focusing on the poultry and wheat sectors in the UK reveal potential adaptation measures such as transitioning to heat-tolerant chicken breeds and cultivating heat/drought tolerant varieties of wheat.

Summary: The rising salinity of land and water is a significant issue impacting food security, especially in coastal regions like the Ganges River Delta. Despite efforts by households to adapt their food production methods, effective strategies are still lacking. Community-level interventions such as improved irrigation and regulation of saltwater aquaculture show promise, but face challenges in terms of resources and regulation from NGOs and government sectors.

Summary: Based on a review of 57 global food security projection and quantitative scenario studies published in the past two decades, it is projected that the total global food demand will increase by 35% to 56% by 2050, while the population at risk of hunger is expected to change by -91% to +8%. Both ranges are significantly lower than previous projections.

Summary: Existing research on agricultural insurance is mostly concentrated in high-income countries with crops as the main insured products. Research on crop insurance is correlated with regions where historical extreme weather disasters are frequent, but there is a surprisingly low correlation between future climate change induced temperature increases and current research on crop insurance.

Summary: Food system innovations are crucial in achieving multiple Sustainable Development Goals, but they can lead to profound changes that impact different parts of the global food system simultaneously. It is important to embed innovations as part of systemic changes to avoid unintended negative consequences and address emerging trade-offs involving social aspects like inequality and social justice. Well-planned transition pathways, careful monitoring of key indicators, and transparent science targets at the local level are essential in managing trade-offs with undesirable outcomes.
