Read the following passage carefully:
"To reverse land degradation and combat declining groundwater tables in semi-arid agricultural zones, several regional development authorities have introduced financial subsidies for smallholder farmers adopting agro-forestry practices. Under this scheme, farmers receive direct annual cash transfers for integrating native nitrogen-fixing tree species alongside seasonal millet crops. Proponents contend that establishing multi-tiered canopy cover reduces evaporative moisture loss from the soil and restores organic carbon levels over a five-year cycle. However, field evaluations indicate that adoption rates remain sub-optimal among tenant farmers, who rent land on short-term annual leases. Because tree species require three to four years to mature and yield tangible micro-climatic and soil-enrichment benefits, tenant farmers hesitate to invest labour and land capital into long-term ecological improvements that primarily accrue to non-resident landowners. Consequently, policymakers are considering extending minimum lease duration mandates to align tenant security with the gestation period of agro-forestry interventions."
Statement: The author's suggestion to extend minimum lease duration mandates rests on the implicit assumption that tenure insecurity is a primary bottleneck preventing tenant farmers from investing in agro-forestry initiatives.
