The survey conducted on the importance of mangroves by developing a questionnaire which includes it the respondent who agree to increase from KES 300 to,500) and those who agree to decrease by 200 Using Contingent valuation Model (CVM) (table ) to analyse the data Please explain how you use the physical forest survey in the final analysis? The forest survey data will help to show how much carbon is sequestered as mangrove forest act as carbon sinks This will help in calculating the total carbon benefit tCO2 and sold in Us dolars How did you carry out the social survey and how was the respondent selection random? A social survey was conducted on September 2017 in the two villages of Gazi Bay Using village heads two enumerators were used to translate the questionnaires into Swahili language Data collection was through questionnaires and interviews where by 205 households were randomly selected from the two villages Key informants were chosen because they engage in Gazi activities daily These were; Gazi women, BMU chairman, village heads Major sections included demographics, projects impacts, participation in project activities and importance of the mangroves (II) QUESTIONS Why you choose the year for ranking but not the solutions to improve the carbon trading? I have changed from using years to better management options, Business As Usual (BAU), Management, Alternative livelihood and Empowerment I chose the years because of evaluating the four years of replanting and conserving mangroves …(III) QUESTION Could you please explain clearly how you collect samples for forest structure study ? 10 belts run perpendicular t the show and on each transect set data of tree height, Diameter at breast height tree species was determine …What is the important research that you can use for promethee in Kenya? Promethee in Kenya has not been used but have introduced it and I think it will be applied as from my experience Usually used to rank management Options …………………… …(IV) QUESTION How does the CC important on mangrove forest? Mangrove forest act as carbon sinks, this means that they absorb accumulated Carbon dioxide in the atmosphere and in the process reduces global warming which is a major cause of climate change Usually this is through the process of photosynthesis How to assess the blue carbon and the result of blue carbon content estimation in your studies ………………… The blue carbon was estimated by measuring the Diameter at Breast Height, the species type and other and after getting the this data I use formulas to get the results ……… (V)… QUESTIONS Explain the Willingness to Pay (WTP) in section 17, Page 28? Basing the set rate that tourists pay when they visit the women board walk; normally international visitors pay 300 while local pay 200, a Bid was developed of increasing by as follows (100, 200, 300, 400 to 500) Explain how specific research objectives were solved? The first objective was solved by conducting a social survey on socioeconomic households characteristics by Using village heads two enumerators were used to translate the questionnaires into Swahili language Data collection was through questionnaires and interviews where by 205 households were randomly selected from the two villages The second specific objective was met by performing a Systematic random sampling, rectangular and square plots were established and 10 plots of 10m by 10m plot size were sampled each in conserved forest and reforested area depending on the tree size and density 10 belts were run perpendicular towards the shore and 10 plots measuring 10m by 10m were developed along these belts Within each plot, tree height, stem diameter at breast height (DBH), species of all trees with DBH of greater or equal to 2.5cm were recorded The tree height was measured using a graduated pole and DBH was measured using a forester Calliper Data obtained included; basal area, absolute density and frequency, also relative derivatives were calculated The important (IV) of each species and the complexity index (CI) of the stand were calculated The third objective I was to find out how carbon stocks can be converted to tradable credit credits and how much of the total carbon benefit and how much Us dollars Below table shows the calculations Carbon Benefits Calculation Activity Forest Type Area ( Ha) Carbon Total project Annual Income $ * benefit (tCO2 initiative ha-1 yr-1) activities( tCO2 yr-1 Avoided Natural Mixed 100 Deforestation 18 ( based on 100 1800 * 18= 1800*6= 1800 10800 sequestration in mature forest ( recovering forest) Reforestation Rhizophora plantation 29 (based on 7* 29= 203 203*6 = 1218 12 year 203 old plantation Reforestation New plantation after ( Sonneratia) increasing but 5*4= 20 20*6= 120 to 20 ( 10 after 10 years) Total 2023 benefit annum tCO2 $12138 per potential annual income for credits Objective I used Promethee model to determine the impact of carbon trading to the Gazi community The data was collected from Women Board walk, Beach Management Unity, and Mikoko pamoja project, see the table below: Options Revenue fish Income Tourists Board walk Employment cash BAU 9708 114065 100 459 202050 Management 13640 134243 150 458 188605 Alternative 12000 175896 300 198 110750 10027 206456 600 98 93175 livelihood Empowerment MINISTRY OF EDUCATION & TRAINING SOCIALIST REPUBLIC OF VIETNAM NHA TRANG UNIVERSITY Independence - Freedom - Happiness REPORT OF THESIS CORRECTION At the request of the thesis evaluation Committee Full name:Beatrice Njeri Obegi ………………… St.code: …58CH161…… Thesis title: “ ASSESSMENT OF BLUE CARBON AND CARBON TRADING; A CASE STUDY OF GAZI BAY MANGROVE FOREST, KENYA ” Supervisor(s): Prof Curtis Jolly …………… ………………………………………………………………… Study Program: … Marine Ecosystem Based Management and Climate Change ……………………… Thesis defense date: …8th June 2018……………………… ……………………………………… Based on the requirements of thesis evaluation committee I would like submit the revised thesis statement as follows: Request 1: state the Committee's amendment request…According to the committee’s advice that the a table consisting data for promethee must be included in the thesis, this has been done and can be accessed in page 34 of my thesis Content has been modified: For example: …Upon Committees request table on page 38 was added.… ……………………………… ………………………………………………………………………………………………………… ………………………………………………………………………………………………………… Request 2: state the Committee's amendment request The committee advised me to state the method used to collect data on Willingness to pay (WTP) I developed a bid on my questionnaire basing on what price they charge each tourist who come to visit the women board walk And a questionnaire I asked them can we increase this charges from 300 to 400 or 500 or 600 or 700 or 800 or 900 or 1000 Content has been modified: For example: Upon the committee’s request a Bid for what people are willing to pay and using Contingent Valuation Method the mean Wtp was calculated using excel model page28………………………………………………………… ………………………………………………………………………………………………………… ………………………………………………………………………………………………………… Request 3: state the Committee's amendment request The committee advised me to use options instead of using years Following that request the best options to suit the model were chosen; BAU, Management, Alternative livelihood and Empowerment Content has been modified: For example: Changed from; 2013 to BAU, 2014 Management, 2015 to Alternative Livelihood and 2016 to Empowerment …………………………………………………………… ………………………………………………………………………………………………………… … Request 3: state the Committee's amendment request : The committee requested me to format my thesis according to NTU regulations Content has been modified: The citations were done using Harvard Style and formatting using Mendeley software Nha Trang, date13, month 06, year 2018 ...
