Abstract This study aims to determine the level of damage and estimation of rehabilitation value in the Lantebung Mangrove Ecotourism, Makassar City. The sampling technique was carried out using a survey technique with a purposive sampling method. The size of the plots made is 20 m x 50 m with a total of 8 plots. The level of mangrove damage is determined based on land cover and vegetation density. Estimating the value of ecotourism rehabilitation is based on the Regulation of the Director-General of Natural Resources and Ecosystem Conservation P.8/KSDAE/SET/REN.2/10/2017 concerning Standards for Activities and Costs for Conservation of Natural Resources and Ecosystems. The results showed that there were two types of mangrove species, namely Rhizophora mucronate and Avicennia alba. Lantebung Mangrove Ecotourism has a vegetation cover of 82% with a vegetation density of 1,760 individuals/ha, so that the level of damage to mangroves is in a good category. In general, damage to Lantebung Mangrove Ecotourism is caused by converting mangrove forests into fishponds and settlements. The total cost of mangrove forest rehabilitation is IDR. 350,220,000

The Civil Engineering course teaches different subjects in its academic program, which has in their educational task to offer knowledge to students, their intervention in the environmental space, within the framework of their actions as future civil engineers. The objective of the research is to reflect on the knowledge acquired in the environmental training of students of the civil engineering career. For this purpose, the standardized survey technique was used with structured questions that collected the work of the educational program of the race and was applied to 75 students of the different levels. The result obtained allowed to know to what extent the environmental training of students, has repercussions on the preparation of future civil engineers, in addition to the degree of concern for environmental problems and the predisposition to work in order to reduce the impacts derived from the professional practice of The Civil Engineering, taking into account the implication of the sustainable development in the academic formation. During the investigation it was verified that students are aware of the importance of preservation and respect for nature through the use of clean energies, where they have expressed concern about contamination and depletion of natural resources. The results obtained can have a positive influence on the constructive future of the province, depending on the implementation of an appropriate sustainable development policy.

Available Information

The effect of vegetation in hydraulic computations can be significant. This effect is important for flood computations. Today, the necessary terrain information for flood computations is obtained by airborne laser scanning techniques. The quality and density of the airborne laser scanning information allows for more extensive use of these data in flow computations. In this paper, known methods are improved and combined into a new simple and objective procedure to estimate the hydraulic resistance of vegetation on the flow in the field. State-of-the-art airborne laser scanner information is explored to estimate the vegetation density. The laser scanning information provides the base for the calculation of the vegetation density parameter ωp using the Beer–Lambert law. In a second step, the vegetation density is employed in a flow model to appropriately account for vegetation resistance. The use of this vegetation parameter is superior to the common method of accounting for the vegetation resistance in the bed resistance parameter for bed roughness. The proposed procedure utilizes newly available information and is demonstrated in an example. The obtained values fit very well with the values obtained in the literature. Moreover, the obtained information is very detailed. In the results, the effect of vegetation is estimated objectively without the assignment of typical values. Moreover, a more structured flow field is computed with the flood around denser vegetation, such as groups of bushes. A further thorough study based on observed flow resistance is needed.

Set Up

Coastal regions of India are prone to sea level rise, cyclones, storm surges, and human-induced activities, resulting in flood, erosion, and inundation, and some of these impacts could be attributed to climate change. Mangroves play a very protective role against some of these coastal hazards. The primary aim of the study was to estimate wave energy attenuation by mangrove vegetation using modeling, and to validate the model results with measurements conducted off Mumbai coast, where a mangrove forest is present. Wave measurements were carried out from 5–8 August 2015 at three locations in a transect normal to the coast using surface-mounted pressure-level sensors in spring tide conditions. The measured data presented wave height attenuation of the order of 52%. Model set-up and sensitivity analyses were conducted to understand the model performance with respect to vegetation parameters. It was observed that wave attenuation increases with an increase in drag coefficient, vegetation density, and stem diameter. For a typical set-up in the Mumbai coastal region having a vegetation density of 0.175 per m2, stem diameter of 0.3 m, and drag coefficient varying from 0.4 to 1.5, the model reproduced attenuation ranging from 49% to 55%, which matches reasonably well with the measured data. Spectral analysis performed for the cases with and without vegetation very clearly portrays energy dissipation in the vegetation area. This study also highlights the importance of climate change and mangrove vegetation.

Background and Objectives: The National Cancer Database (NCDB) captures nearly 70% of all new cancer diagnoses in the United States, but there exists significant variation in this capture rate based on primary tumor location and other patient demographic factors. Prostate cancer has the lowest coverage rate of all major cancers, and other genitourinary malignancies likewise fall below the average NCDB case coverage rate. We aimed to explore NCDB coverage rates for patients with genitourinary cancers as a function of race. Materials and Methods: We compared the incidence of cancer cases in the NCDB with contemporary United States Cancer Statistics data. Results: Across all malignancies, American Indian/Alaskan Natives subjects demonstrated the lowest capture rates, and Asian/Pacific Islander subjects exhibited the second-lowest capture rates. Between White and Black subjects, capture rates were significantly higher for White subjects overall and for prostate cancer and kidney cancer in White males, but significantly higher for bladder cancer in Black versus White females. No significant differences were observed in coverage rates for kidney cancer in females, bladder cancer in males, penile cancer, or testicular cancer in White versus Black patients. Conclusions: Differential access to Commission on Cancer-accredited treatment facilities for racial minorities with genitourinary cancer constitutes a unique avenue for health equity research.
