Read the passage below carefully and match each excerpted statement (1–4) with its correct structural role in summarizing the text.

For decades, the promotion of full-sun cocoa monoculture across West Africa promised immediate high yields but led to rapid soil degradation and heightened vulnerability to climatic shocks. Recent agricultural interventions in Southwestern Nigeria have pivoted toward traditional agroforestry, reintroducing native shade trees such as Milicia excelsa alongside cacao plants. Microclimate measurements reveal that these canopy trees effectively regulate ambient temperatures, retain soil moisture during prolonged droughts, and suppress invasive weed species. Furthermore, fallen leaf litter naturally replenishes organic soil nitrogen, significantly diminishing farmers' reliance on expensive synthetic fertilizers. Although initial canopy establishment slightly delays maximum cocoa pod production by two seasons, the long-term ecological balance ensures sustained yield stability. Critics often argue that shade canopy maintenance demands excessive manual labor, yet field assessments confirm that reduced chemical purchases offset management costs. Ultimately, integrating native trees into cocoa cultivation provides a resilient agricultural framework that preserves biodiversity while safeguarding rural livelihoods against erratic weather patterns.
