There is definitely a strong relation between osmosis pressure and water activity. Osmosis is the movement of water from high pressure to low pressure.
Water or liquid move naturally from lower concentration to higher concentration. The drive force is called osmotic pressure. No additional pressure need to drive osmosis process. Reverse osmosis, is apply pressure to fight against osmotic pressure. It do need additional pressure to reverse the osmosis process. It is comparing a zero additional pressure with any positive additional pressure thus of cause reverse osmosis require more pressure.
concentration gradients, osmosis, and hydrostatic pressure
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.

Water enters into plants by Osmosis and water causes turgor pressure Tugor definition= the state of turgidity and resulting rigidity of cells (or tissues), typically due to the absorption of fluid.
Tonicity is measure of the effective of osmotic pressure. Osmosis is the minimum pressure which needs to be applied to a solution.
The movement of water and electrolytes is primarily regulated between fluid compartments by hydrostatic pressure and osmotic pressure.
Diffusion, Osmosis
a pressure greater than the osmotic pressure is applied in the opposite direction osmosis is occurring.
