The Effect of Climate Smart Agricultural (CSA) Practices in Sustainability: A Case Study Focusing on Wheat Cultivation in Lithuania

Conventional agricultural production systems are increasingly challenged to balance environmental sustainability with economic performance, highlighting the need to systematically evaluate climate-smart agricultural practices as viable alternatives. The primary objective of the present work is to assess the environmental and economic benefits of implementing different Climate Smart Agricultural (CSA) practices in the agricultural sector. For this purpose, four different CSA practices, including intercropping, renewable energy, variable rate fertilizer and no-tillage system, were studied in wheat cultivation in Lithuania. Subsequently, their environmental and economic performance was compared to a conventional wheat producing farm. For the environmental performance, Life Cycle Assessment (LCA) analysis was performed following the respective ISO recommendations. Based on the results, the incorporation of CSA practices in the agricultural sector can lead not only to substantial improvements in environmental performance but also to notable economic benefits, depending on the selected practice. Regarding their environmental performance, the most prominent studied CSA was renewable energy that minimizes greenhouse gas emissions, followed by variable rate fertilization. The economic analysis showed intercropping to be the most profitable option, with the total profit being 792 €/ha, while no-tillage also showed competitive results, with subsidies in each studied system playing a major role in the economic performance. Conversely, variable rate fertilization and renewable energy integration highlighted trade-offs between environmental advantages and short-term economic feasibility. Overall, the adoption of CSA practices represents a promising pathway toward more sustainable and resilient agri-food systems.
