Technical assistance is considered crucial for improving local livelihoods and increasing production potential. However, rural development interventions suffer from a lack of financial and human resources and have undesirable social and environmental impacts. Targeted changes in critical contextual factors can be an effective and low-cost option to facilitate sustainable farmer responses. Empirical studies analyzing these dynamics are scarce. To better understand contextual changes and local responses leading to tangible landscape-level outcomes, we conducted an in-depth case study in the districts of Soritor and Jepelacio, in the northwestern part of the San Martin region of Peru, a typical forest frontier area where smallholder farmers have settled over the last 40 years. The study shows that villages followed a standard development trajectory characterized by quantitative and qualitative improvements in infrastructure and services, leading to market integration and better quality of life. These improvements correlate with the specialization and intensification of farmers' production systems, along with increased pressure on forests due to the influx of new settlers. Consolidation was observed three to four decades after settlement began. While the study sheds light on the relationships between contextual changes, farmer responses, and impacts over space and time, it also makes clear the difficulties to influence the observed development pathway. The results support the promotion of extension, financial, logistical, and legal instruments tailored to local realities, to facilitate local action for sustainable development and avoid the negative social and environmental consequences of economic growth.
