    1. Collaborative and Integrated Watershed Management (CIWM): Evaluation of Critical Success Factors in Beysehir Lake Basin

    2. 2

    3. Aim: To investigate the critical success factors of CIWM in Beysehir Lake Basin (BLB). 3

    4. Case Study: Beysehir Lake Basin (BLB) 4

    5. Beysehir Lake has international importance according to Ramsar Convention criteria also Important Bird Area (IBA) and Important Plant Area (IPA) statuses. Various zones of the lake and its basin are protected as 1st, 2nd and 3rd Degreed Natural Sit statuses and declared as National Parks called Lake Beysehir and Kizildag. Also there are archeological sits in the basin. BL has drinking and potable water conservation area character. Beysehir Lake Basin (BLB) suffers from lots of environmental and socio-economic problems. Variations in water level due to inappropriate water policy and non-point source pollution in the lake have become striking environmental issues at the basin. 5

    6. The Main Research Questions: What is the crucial problem of the BLB? What is the most appropriate watershed management strategy that enables ecological and socio-cultural sustainability of the basin? How much important to take most advantage of the basin’s Strengths and Opportunities or to reinforce most the Weaknesses and develop the best defense to the Threats? 6

    7. Focus: to explore the most appropriate watershed management strategy for BLB from the perspective of experts such as scientists, engineers, urban planners, hydrologists etc. 7

    8. Methodology: SWOT AND AHP SWOT Technique: The ultimate success of a watershed management is largely dependent on the accuracy of an effective situational assessment. SWOT technique is one of the best and the simplest in situational assessment. The Analytical Hierarchy Process (AHP): AHP is thought to be a method and planning framework with potential for implementation of CIWM. AHP provides a systematic method for comparison and weighting of multiple criteria and alternatives by decision-makers. 8

    9. Our proposal is to structure a hierarchy for the CIWM process based on a SWOT study, and to use AHP to estimate a global value for each one of proposed strategies. SWOT analysis supports the decision situation while AHP measures the relative importance of the SWOT factors. The paper offers a systematic approach and analytical means with a combination of SWOT matrix and Analytic Hierarchy Process (AHP) and evaluates the most appropriate watershed management strategy. 9 Methodology: SWOT AND AHP

    10. Implementation of the methodology 10

    16. Step 2. Hierarchical Structure: 16 Figure shows the hierarchy used in the study. The AHP begins with the development of a decision hierarchy with a main goal, sub- objectives and alternatives (strategic objectives). Top level is the Main Goal: develop the best watershed management strategy enables environmental and socio-economic sustainability together. How much important are the internal Strengths & Weaknesses and the Opportunities & Threats, arising from external environment, or what degree should be overrated to achieve the purposes specified. Which are the most important problems of the basin? Which is the safest course leads to improve the lake's environmental conditions and living conditions of the basin residents? SWOT and AHP integration has been exploited to reach the answers of these questions at the level of experts. Figure shows the hierarchy used in the study.

    17. Step 3. Pairwise Comparison: 17 Figures show the priority of SWOT factors. Participants extremely overrate to develop the best defense to the Threats (43 %). Hereafter they overrate to take most advantage of the Strengths (22 %) and Opportunities (18 %), as well as to reinforce most the Weaknesses (17%). It is explicitly pointed out that most interventions to basin’s water system from outside the basin [T 8] is the most overrated SWOT factor by the experts. All the same overhunting [T 5] and decline in the amount of lake water [T 3] threat factors are overrated mostly. Figures show the priority of SWOT factors.

    18. Step 4. Strategy formulation using TOWS Matrix: 18 The TOWS matrix contains six proposal strategic objectives (SO) and their sub-strategies take most advantage of the Strengths and Opportunities, as well as to reinforce most the Weaknesses and develop the best defense to the ThreatsThe TOWS matrix contains six proposal strategic objectives (SO) and their sub-strategies take most advantage of the Strengths and Opportunities, as well as to reinforce most the Weaknesses and develop the best defense to the Threats

    19. Step 5. Evaluation of Proposed Strategies: Weights of proposed strategies are calculated. 19

    20. Strategy Development and Evaluation Matrix 20 The results for global evaluation made by the experts for the six proposal strategies is shown in this table: The results for global evaluation made by the experts for the six proposal strategies is shown in this table:

    23. Empirical results: 23 Our findings suggested that amongst 6 strategic objectives, [SO 1] (19 %) has been perceived as the most important, while [SO3] (17, 6 %), also considered to be significant respectively. [SO 2] and [SO 6] (17 %) were ranked highly important by participants while [SO 5] (15, 7 %) and [SO 4] (13, 6 %) were listed as less significant. Experts thought Agricultural Development Strategy [SO 1, Maxi- Maxi] uses strengths to maximize the opportunities as the most important approach to solve basin’s problems in this way reach to successful CIWM.

    24. Efficiency of the Most Desirable Strategy [SO 1] on SWOT Factors: Agricultural Development Strategy [SO 1] takes most advantage of Strength-4 and Opportunity-3, reinforces the Weakness- 4 and develops the best defense to the Threat- 3. 24

    25. Concluding remarks This study evaluated and identified the crucial CIWM success strategies for BLB. SWOT-AHP integration model used in this study presents a simplified, transparent and fast decision-making process; thus, ideal to be used in situations with limited data availability or on the contrary intensive data existence. The final outcome from this approach is, henceforth, helps in selecting the best watershed management strategy for the goal- to sustain socio-cultural and environmental sustainability-in the basin. The results are reasonable and useful for the practical work of water conservancy. The main findings are as follows: 25

    26. Global Evaluation for the six Proposal Strategies: 26

    27. Global Evaluation for the six Proposal Strategies: 27

    28. Global Evaluation for the six Proposal Strategies: 28

    29. Global Evaluation for the six Proposal Strategies: 29

    30. As a second step/future work of this research, it is aimed to test SWOT-AHP based model with the local authorities and the local people of the basin to be able to compare the best management strategy preference differences. It is believed that the outcomes of the research and the further studies will contribute to the build CIWM and also will raise basin residents’ awareness on importance of Beysehir Lake. 30
