The coastal region surrounding Charleston, South Carolina—commonly referred to as the Lowcountry—is a place famous for its foodways. Lowcountry cuisine is often portrayed as convivial and celebrated as multicultural. This article argues, however, that much of the Lowcountry's food culture is marked by the region's history of racism. It is important not only to recognize this dominant tendency, but also to acknowledge attempts to challenge it. Thus, this article also highlights recent efforts to articulate an alternative vision of the region and its cuisine. By investigating what is at stake when regional cuisines are contested, I attempt to place the future of Lowcountry food on firmer footing.

Abstract The changes in the number of wet days (NWD) in Oman projected by climate models was analyzed, focusing mostly on variation of precipitation intensity and its effect on total annual precipitation (PTOT) in the future. The daily precipitation records of 49 gage stations were divided into five regions. Of the five general circulation models studied, two of them were selected based on their performance to simulate local-scale precipitation characteristics. All regions studied, except the interior desert region of the country, could experience fewer wet days in the future, with the most significant decreases estimated in southern Oman. The contribution from the cold frontal troughs to the PTOT in the northeast coastal region would decrease from 85% in the 1985–2004 period to 79% during the 2040–2059 period and further decrease to 77% during the 2080–2099 period. In contrast, results depict enhanced tropical cyclone activities in the northeast coastal region during the post-monsoon period. Despite the decreases in the NWD, PTOT in all regions would increase by 6–29% and 35–67% during the 2040–2059 and 2080–2099 periods, respectively. These results, therefore, show that increases in precipitation intensity dominate the changes in PTOT.

Aims: The aim of the study was to assess the indicator based climate change vulnerability of south west coastal Bangladesh and its future. Place of Study: Four districts form south west coastal Bangladesh, having a total of 50 upazilas, have been selected as the study area. They are Satkhira, Khulna, Bagerhat, Pirojpur, Barguna and Patuakhali districts. Methodology: This study has been conducted, using multivariate statistical techniques, to assess the vulnerabilities of the coastal region of Bangladesh by considering the IPCC framework of vulnerability studies. A total of 31 indicators have been selected of which 23 are socio-economic and 8 are biophysical which have been retrieved from the secondary sources. Principal Component Analysis (PCA) has been applied to derive unbiased weights of all indicators considering both present (2011) and the future (2050) climate change scenarios. Results: This study has identified 7 principal components through PCA which has been grouped as PC1 (Demographic Vulnerability), PC2 (Economic Vulnerability), PC3 (Climatic Vulnerability), PC4 (Health Vulnerability), PC5 (Agricultural Vulnerability), PC6 (Infrastructural Vulnerability) and PC7 (Water Vulnerability). For all 7 PCA groups (termed as vulnerability profile), the number of high and medium vulnerable coastal Upazilas will be significantly changed in the future. No of highly vulnerable Upazila will increase from 0 to 1 for PC1, unchanged for PC2, increase from 0 to 1 for PC3, from 32 to 33 for PC4, from 47 to 68 for PC5, decrease from 48 to 46 for PC6, and an increase from 14 to 21 for PC7, respectively. Conclusion: Discrete spatial maps of each profile have been generated to assess the regional variation of all vulnerability profiles across the southwest coastal region of Bangladesh. The findings of this study might be useful for policy makers and planners.

Abstract The hypothesis that global warming during the twenty-first century will increase the land–sea thermal contrast (LSTC) and therefore the intensity of early season precipitation of the North American monsoon (NAM) is examined. To test this hypothesis, future changes (2075–99 minus 1979–2004 means) in LSTC, moisture flux convergence (MFC), vertical velocity, and precipitation in the region are analyzed using six global climate models (GCMs) from phase 5 of the Coupled Model Intercomparison Project (CMIP5) under the representative concentration pathway 8.5 (RCP8.5) emission scenario. A surface LSTC index shows that the continent becomes warmer than the ocean in May in the North American Regional Reanalysis (NARR) and ECMWF Interim Re-Analysis (ERA-Interim) and in June in the mean ensemble of the GCMs (ens_GCMs), and the magnitude of the positive LSTC is greater in the reanalyses than in the ens_GCMs during the historic period. However, the reanalyses underestimate July–August precipitation in the NAM region, while the ens_GCMs reproduces the peak season surprisingly well but overestimates it the rest of the year. The future ens_GCMs projects a doubling of the magnitude of the positive surface LSTC and an earlier start of the continental summer warming in mid-May. Contrary to the stated hypothesis, however, the mean projection suggests a slight decrease of monsoon coastal precipitation during June–August (JJA), which is attributed to increased midtropospheric subsidence, a reduced midtropospheric LSTC, and reduced MFC in the NAM coastal region. In contrast, the future ens_GCMs produces increased MFC and precipitation over the adjacent mountains during JJA and significantly more rainfall over the entire NAM region during September–October, weakening the monsoon retreat.

Model Precipitation

The aim of this study is to evaluate climate model hydrological parameters in comparison to recorded hydrological data and estimate the impacts of climate change on water balance. For this purpose, a combination of climate model precipitation and temperature data and Thornthwaite method was applied for the period 1988-2000 and the future periods 2028-2040, 2058-2070 and 2088 2100. The application of this combination was carried out in a coastal region in Southeastern part of Korinthiakos Gulf (southern Greece). The area is suitable for this target, because it is characterized by urbanization, intensive agriculture and tourism development, with increasing water demands. The evaluation of climate model parameters in comparison to observed data shows that the RegCM3 model is a reliable model. According to the future projections and the Thornthwaite method, the real evapotranspiration is estimated to increase, as a result precipitation decrease and temperature increase.

This paper examines ethnohistoric and archaeological evidence of Inka imperial strategies for controlling resources and people in the Titicaca Basin and the coastal valleys of southern Peru and northern Chile, and suggests that Inka imperial policies were adapted to meet local conditions in a series of dynamic political and economic interactions. In the coastal region between the Tambo Valley of southern Peru and the Azapa Valley of northern Chile, Inka policies included, variously, the resettlement of labor colonists (mitmaqkuna), the direct incorporation of coastal groups, and the maintenance of alliances with autonomous coastal elites. Altiplano elites exploited the imperial system to extend their own networks of colonization and exchange. Recent archaeological surveys in the Ilo-Ite coastal region, as well as unpublished data collected by Gary Vescelius between 1958 and 1960, indicate that the Inka developed more direct control of the south-central coast than earlier polities had achieved, but that imperial control over this region was limited and influenced by the persistence of autonomous coastal groups. Groups around Ilo remained fairly independent, while parts of the Tambo and Sama valleys and the Quebrada Tacahuay were brought under direct imperial control.

Climate change a global threat to the modern human civilization. Today the man focus of all countries is to achieve sustainable development goal to make life health and possible for the future generation. A sustainable development with sustainable growth without environmental Hazard. One of which is promotion of blue economy which involves the sustainable use of oceans, seas and water resources. A country like India which has a coastline of 7500 km above and home to so many islands and ports which provides great opportunity for India in the blue economy. India is also the second largest producer of fish which not only adds to the blue economy but also helps in resolving the issue of food security and nutrition in the country, can help to generate employment and also increase the income of farmers. The government is investing in Billions in the fishery sector for infrastructure development and the growth of the industry with the aim to make India Atma nirbhar. Blue economy will help to reduce the water waste management problem, climate change, pollution free environment, promote tourism, we need to strengthen our coastline security and maritime security for the smooth conduct of blue economy and bring in advance technologies that can stand against harsh weather patterns.

The Relationship

Kema coastal region is a coastal tourist area quite a lot of visitors especially during the holidays. Most of the population in this region is fishing. This region had experienced 4 meter tsunami on 6 September 1889 by an earthquake with a magnitude of 8.0 on the Richter scale in the Moluccas Sea epicenter position ± 72 km southeast of Kema. The earthquake caused a tsunami that has the potential to re-occur in the future. The purpose of this study was to calculate how much the maximum magnitude earthquakes likely to occur in the Moluccas Sea and map the run-up tsunami caused by the earthquake in Coastal Areas of Kema. Calculation of maximum magnitude and tsunami run-up using the relationship between the frequency and magnitude of the Guttenberg-Richter earthquake and Imamura tsunami software, then run up the tsunami mapped using GIS software. Generated that could potentially occur in the Moluccas Sea earthquake with a magnitude of 8.5 on the Richter scale can cause a tsunami to hit the coast Kema Beach area on 10 minutes after the earthquake, the tsunami run-up heights reached 13.9 meters. Mapping the tsunami run-up showed that the entire coastal region of Kema is tsunami prone areas© Wilayah pesisir Kema merupakan kawasan wisata pantai yang cukup banyak pengunjungnya terutama pada saat hari libur. Sebagian besar penduduk di wilayah ini adalah nelayan. Wilayah ini pernah mengalami tsunami 4 meter pada tanggal 6 September 1889 akibat gempa bumi dengan magnitudo 8,0 Skala Richter di Laut Maluku dengan posisi pusat gempa ± 72 km tenggara Kema. Gempa bumi yang menimbulkan tsunami ini berpotensi terulang kembali pada waktu yang akan datang. Adapun tujuan dari penelitian ini adalah menghitung berapa besar magnitudo maksimum gempa bumi yang berpeluang terjadi di Laut Maluku dan memetakan run up tsunami akibat gempa bumi tersebut di wilayah pesisir Kema. Perhitungan magnitudo maksimum dan run up tsunami menggunakan hubungan antara frekuensi dan magnitudo gempa bumi Guttenberg-Richter, serta software tsunami Imamura, yang kemudian run up tsunami dipetakan dengan menggunakan software GIS. Dihasilkan bahwa di Laut Maluku berpotensi terjadi gempa bumi dengan magnitudo 8,5 Skala Richter yang dapat menimbulkan tsunami hingga melanda di pantai wilayah pesisir Kema pada menit ke 10 setelah kejadian gempa bumi, dengan ketinggian run up tsunami mencapai 13,9 meter. Pemetaan run up tsunami tersebut menunjukkan bahwa seluruh wilayah pesisir Kema adalah daerah rawan tsunami©
