Translating Resilience to the Field: Developing Crops for Extreme Climates
摘要
The growing threats posed by climate change necessitate an urgent focus on developing crops that can withstand extreme environmental conditions, such as prolonged droughts, heat waves and soil salinity, while maintaining high yield potential. This chapter delves into the intricate challenges and strategies of translating resilience traits from laboratory settings to real-world agricultural fields. We explore the balance between yield and resilience, emphasizing the importance of multi-stress field trials that mimic the complex environmental conditions crops will face by 2050. Key regions currently vulnerable to climate change, such as Sub-Saharan Africa, South Asia and the Mediterranean Basin, are highlighted, along with the significant cash and subsistence crops vital to these areas. Through case studies, we examine the successes and challenges of integrating advanced breeding techniques, such as CRISPR/Cas9 gene editing, marker-assisted selection, and genomic selection, into traditional breeding programs to develop climate-resilient crops. Special attention is given to orphan crops and traditional agricultural knowledge, which offer naturally resilient traits that can be leveraged in modern breeding programs. The chapter also discusses the critical role of global collaboration and public-private partnerships in scaling these innovations, ensuring they are accessible to farmers worldwide, particularly in developing regions. Finally, we outline future directions for research and development in climate-resilient agriculture, calling for continued investment in technology, sustainable practices, and multi-disciplinary collaboration to secure global food systems in an increasingly unpredictable climate.
