The book titled “New Dynamics in Agriculture” comprehensively examines the agriculture sector amid multidimensional transformations caused by climate change, population growth, food security challenges, resource constraints, and economic fluctuations. It evaluates agriculture beyond production focus, considering environmental sustainability, social equity, economic efficiency, and strategic management. The importance of circular economy and urban agriculture practices for resource efficiency and sustainable production models is emphasized, while the role of rural women in agricultural production and gender equality are analyzed. Food security issues in Turkey and strategic management approaches are explored in detail; challenges like rising input costs, dependency on imports, water scarcity, climate impacts, and market structure are discussed. The historical development, advantages, disadvantages, and greenhouse gas emissions impacts of pesticide use are assessed, alongside their regional distribution and increasing trends in Turkey. Moreover, the economic value of walnut production is analyzed holistically according to product components, quality criteria, marketing, and processing stages. Finally, the strategic role of the antioxidant product range in the food industry—extending shelf life, reducing costs, and enhancing brand value—is thoroughly discussed, considering their technological roles and economic benefits. Offering a multidisciplinary perspective on agricultural and food system sustainability and innovative solutions, the book serves as a significant resource for academia, policymakers, and industry stakeholders.
