В данном исследовании представлен всесторонний анализ воздействия изменения климата на региональную экономику стран БРИКС — Бразилии, России, Индии, Китая и Южной Африки — с помощью компьютерных статистических методов и многомерного анализа экономических параметров. В исследовании использовались методы программирования, сравнительные методы, методы анализа и синтеза, методы индукции и дедукции, а также методы кабинетного исследования. В исследовательской программе использовался обширный код, написанный автором на языке программирования R, для анализа взаимосвязи климата и экономики стран БРИКС. Значение БРИКС заключается в том, что он представляет собой новое экономическое, глобальное, торговое и финансовое содружество, объединяющее страны с быстрым экономическим и демографическим ростом в синергии с высокими инвестициями, либерализацией рынка, взаимным сотрудничеством и передачей знаний и технологий. Проанализированные показатели демонстрируют критическую взаимосвязь между изменением климата, глобальным потеплением и ситуации в сельском хозяйстве. Исследование приходит к выводу о необходимости скоординированных действий между странами БРИКС, подчеркивая важность развития механизмов передачи технологий для адаптации сельского хозяйства к изменению климата, внедрения новых технологий, финансовых инструментов, способствующих повышению устойчивости сельского хозяйства, координации цепочек поставок внутри блока и комплексных стратегий развития сельских районов для защиты продовольственной безопасности и экономической стабильности в регионах. </p></abstract><trans-abstract xml:lang="en"><p>Climate change has emerged as one of the most significant systemic shocks to regional and global economies in the 21st century, with particularly severe implications for agricultural production, food security, and economic stability. This study presents a comprehensive analysis of climate change impacts on the regional economies of BRICS nations—Brazil, Russia, India, China, and South Africa—and their neighboring countries through computer integrated statistical techniques and multidimensional economic parameter analysis. The research employed programming methods, comparative methods, analysis and synthesis methods, induction and deduction methods, as well as desk research methods. The research program utilized extensive code written by the author in the R programming language for the analysis of the BRICS Climate-Economy relations. The significance of BRICS lies in the fact that it represents a new economic, global, trade, and financial power, uniting countries with rapid economic and demographic growth in synergy with high investments, market liberalization, mutual cooperation, and the transfer of knowledge and technology. The analyzed indicators show a critical correlation between climate change and global warming and agriculture. The study concludes that coordinated action among BRICS nations is essential, emphasizing the development of technological transfer mechanisms for climate-adaptive agriculture, implementation of new technologies, financial instruments promoting agricultural resilience, supply chain coordination within the bloc, and comprehensive rural development strategies to protect food security and economic stability across regions. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>БРИКС</kwd><kwd>изменение климата</kwd><kwd>глобальное потепление</kwd><kwd>сельское хозяйство</kwd><kwd>экономические показатели</kwd><kwd>взаимосвязь климата и экономики</kwd><kwd>устойчивость сельского хозяйства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>BRICS</kwd><kwd>climate change</kwd><kwd>global warming</kwd><kwd>agriculture</kwd><kwd>economic indicators</kwd><kwd>climate-economy relation</kwd><kwd>agricultural resilience</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pejanović R.
