A good footpath is not a decorative strip beside a road. Width, surface, crossings, driveways, vegetation and construction detours determine whether people can complete an ordinary trip.

Salt is quietly taking productive soil out of circulation

Soil salinisation grows through irrigation, poor drainage, groundwater rise and sea-level intrusion. Recovery requires measurement, water management and farm economics, not a single salt-tolerant seed.
