Book excerpt: Agricultural productivity and sustainability are of the most challenging cases facing the world today with water and land being the limiting factors and increased food demand being the urge. In order to meet the imposed challenges, a wise use of these scarce agricultural resources must be considered. The objective of this research is specially designed to serve the mentioned aim: increasing production by saving space, water, and environment. To meet the above goal, an experiment was designed to measure water and land productivity using a 3-D technique. This technique consisted of vertical columns filled with soil where evaporation was prevented by covering the pipe surface. Another treatment was to keep surface exposed and get the evapotranspiration from the whole pipe. Those two treatments with each containing different density of plantation/ pipe (1, 2, 3 and 4 plants) were compared with the conventional way of plantation. Two crops, strawberry and beans were used in this experiment and results showed a great difference in water and land use using the 3-D technique. In the strawberry experiment the highest water productivity was for the double with a density of three plants/pipe compared to the control and the values were 17.25 kg/m(to the power 3), and 3.62 kg/m(to the power 3), respectively. As for the beans the highest water productivity was for the double pipes with a density of one plant/pipe and the values were 9.93 kg/m(to the power 3), and 1.09 kg/m(to the power 3), respectively.
