Objective: Identify the action that does not enhance agricultural productivity. Agricultural productivity is defined as increasing output relative to input (e.g., land, labor).
Analysis:
\[\begin{array}{rl} \bullet & \text{(A) Expedited land reform implementation: Reforms like assigning land to tillers or consolidating holdings can incentivize farmers to invest, boosting productivity.} \\ \bullet & \text{(B) Focused dryland farming initiatives: Developing and promoting farming techniques for arid/semi-arid zones will enhance output in these historically low-yield regions.} \\ \bullet & \text{(C) Dissemination of scientific farming methods: Utilizing improved seeds, irrigation, and management techniques directly increases productivity.} \\ \bullet & \text{(D) Reduction in cropping intensity: Cropping intensity signifies the number of crops cultivated on a land parcel annually. Lowering this (e.g., from two crops to one) reduces total annual yield from that land, thus decreasing overall productivity. Increasing cropping intensity is a method to boost productivity.} \\ \end{array}\]
Conclusion:
Reducing cropping intensity negatively impacts agricultural productivity, rather than improving it.
