الملخص EN

Egypt is located within the Arab region, which is one of the most regions in the world exposed to water scarcity due to the desert nature of the region.

This highlights the importance of measuring the efficiency and adequacy of the financial / economic and environmental investments in water sector as capital costs, and to what extent it achieves the desired goals in terms of developing water resources and protecting them from waste and pollution.

The research is proposing a logical methodology for linking environmental performance goals in the water resources sector and irrigation with economic performance goals in light of Egypt's Vision 2030 strategy and calculating the weighted sustainable rate of return on investments (WSROI) for the first time in this sector to measure the profitability of the investments in this vital sector.

The essential importance of this research come from the need - in the next years - to raise the sector’s ability to attract foreign investment and private sector to invest in its environmental projects to increase the efficiency of water productivity and rationalize its uses in irrigation.

The research reached several recommendations, the most important of which are: 1) The necessity of linking the economic and environmental performance indicators for each program in a systematic way that enables the decision-maker to track the impact of implementing these programs economically and environmentally to ensure the achievement of water resourcesand irrigation strategy goals 2030.

2) Although SROI or WSROI is likely to be used to measure the sustainable rate of return, the weighted sustainable rate of return (WSROI) shows clearer degrees of impact, indicating that it is more effective in presenting the contribution degree in achieving sustainable development.
