Climate change represents significant challenges to Mediterranean agricultural systems, particularly in dryland contexts, due to the increasing frequency of drought, water scarcity, and soil degradation risks. In this setting, conservation agriculture practices, particularly direct seeding systems, have received growing attention for their potential to influence both environmental performance and farm-level cost structures. This study develops and applies an integrated economic and environmental assessment framework for agricultural production systems implemented under the +Solo +Vida Territorial Program in the Guadiana Valley Natural Park (southern Portugal), based on TRACE methodology to incorporate environmental dimensions into conventional crop and investment accounts. The analysis evaluates implementation and operational costs, fuel consumption, partial greenhouse gas (GHG) emissions associated with agricultural operations, and potential biomass-based carbon retention and operational GHG emissions. Application of the proposed framework indicates that direct seeding systems are associated with lower operational intensity and reduced fuel consumption, which translates into differences in both cost structures and estimated GHG emissions. However, the relationship between economic and environmental performance is not uniform across all dimensions, and trade-offs may arise depending on production conditions and system configurations. Crops and pasture systems also show potential relevance as carbon sinks through biomass accumulation, although this contribution varies across systems. Rather than establishing statistically generalizable relationships, it is demonstrated how integrating crop accounts with environmental indicators can support farmers and decision-makers in jointly assessing economic and environmental performance while accounting for system-specific variability. This approach contributes to ongoing discussions on sustainability assessment, climate change adaptation, and the development of farm-level carbon accounting frameworks.
