| | '''Important''': Ignoring the various limiting framework conditions and restrictions may lead to an over- or under-dimensioned system capacity and an unsustainable operation. As far as an over-dimensioned system is concerned, water abstraction above the safe yield will negatively impact the environment and may result in a violation of the allotted water license/permit. A too small water abstraction may result in a low system utilization rate, or under-irrigation, thus having an impact on financial viability. Sustainability in environmental and financial terms can only be achieved if water availability, system design/outlay, crop production and irrigation management and operation are harmonized from the design stage. | | '''Important''': Ignoring the various limiting framework conditions and restrictions may lead to an over- or under-dimensioned system capacity and an unsustainable operation.

The tool supports the user in identifying suitable areas for solar based irrigation depending on the water sources and pump characteristics.

The final process step of this module is based on the results of the preceding steps 2 – 5 in which important factors related to a sustainable utilization of the water resources designated for the irrigation system have been evaluated. None of these process steps should be skipped and it is very important that the underlying analysis along the logic of these process steps is carried out before the envisaged SPIS is finally designed and planned.
The results of the process steps 2 – 5 almost certainly result in limitations and restrictions with regard to the design and outlay of all system components and also the options for the agricultural production. As water resources are limited and increasingly constrained, sustainability criteria with regard to the exploitation of water resources must always prevail. The determining factor for the irrigation system development is therefore the sustainable water availability – system and production are designed and planned according to the safe yield of the targeted water source!
Substantial need for adaptation and adjustment in predesigned or blue print model systems based on the above principle may arise from the following:
Changes in water availability may also occur when the irrigation has been installed according to the given licenses. Given the global increase in climate variability, it is recommended to design a flexible irrigation system that is resilient towards water scarcity. Steps towards drought resilient irrigation may include e.g. selection of crops with low water demand, high water use efficiency and coping mechanisms such as water buffering or insurances. In this context, the role of collective action and risk sharing among water user should be taken into account.
