Abstract
CONTEXT
Agriculture-driven land conversion poses a significant threat to global biodiversity conservation. Balancing agricultural expansion with conservation is a critical challenge for governments and development partners. Sustainability-oriented agriculture programs such as conservation agriculture and land intensification aim to reduce land conversion and deforestation; however, evidence of their effectiveness remains complex and elusive, especially regarding the role of smallholders.
OBJECTIVE
This study addresses this knowledge gap by systematically mapping the drivers of smallholder land conversion and their interconnections across three focal biodiverse contexts including sub-Saharan Africa, Latin America, and Southeast Asia as well as from a global scale.
METHODS
Using literature that focuses on the nexus of smallholder farmers and agricultural intensification, this study systematically identified the potential of distinct factors and dynamic processes to serve as system leverage points toward improved outcomes for biodiversity, food security, and smallholder livelihoods, using a combination of structural factor analysis, centrality analysis, and feedback loop analysis.
RESULTS AND CONCLUSIONS
The results highlight the importance of strengthening land tenure systems, providing technical support to farmers, improving market access, and prioritizing smallholder livelihoods in mitigating land conversion.
SIGNIFICANCE
Contextual differences emphasize the need for context-specific interventions and further research to explore factors driving land conversion more deeply within specific contextual boundaries. Future studies should map proposed policy interventions onto local systems driving land conversion and incorporate the diverse perspectives of local stakeholders to guide effective and sustainable agriculture interventions.
期刊介绍:
Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments.
The scope includes the development and application of systems analysis methodologies in the following areas:
Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making;
The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment;
Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems;
Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
