Biodiversity Conservation in Agricultural Landscapes: A Review of Ecological Functions and Sustainable Management Practices

Abstract

Biodiversity in agricultural landscapes plays a vital role in sustaining ecosystem functions, enhancing productivity, and ensuring long-term environmental stability. However, rapid agricultural intensification, land-use change, habitat fragmentation, pesticide application, and climate change have significantly contributed to biodiversity loss worldwide. This review article aims to synthesize current knowledge on the ecological functions of biodiversity in agricultural systems and evaluate sustainable management practices that support biodiversity conservation. The review highlights the importance of pollination services, natural pest regulation, and soil health maintenance as key ecosystem functions provided by diverse biological communities in agricultural environments. It further examines the negative impacts of conventional agricultural practices, particularly monoculture farming and excessive chemical input use, which disrupt ecological balance and reduce ecosystem resilience. In addition, the study discusses sustainable approaches such as agroecology, organic farming, agroforestry, crop diversification, and integrated pest management as effective strategies for enhancing biodiversity and ecosystem services. Emerging technologies, including remote sensing, GIS-based monitoring, and precision agriculture, are also identified as important tools for supporting sustainable agricultural landscapes. The findings emphasize the need to balance agricultural productivity with biodiversity conservation through integrated landscape management and supportive policy frameworks. Strengthening farmer education, stakeholder participation, and policy incentives is essential for promoting biodiversity-friendly practices.
