Cities are the engines of economic growth. The world population is getting concentrated in urban areas across the globe. In the year 2015, 54% of the population lived in urban areas, which contributed to 80% of the world’s gross domestic product. It is a challenging task for planners to manage the urban system with the available resource constraint...

... capacity (Graefe 1984) are some of the connotations. The urban carrying capacity is one such connotation, this deals with the number of people in an urban system could carry and maintain the desired level of quality of life. The work done by the IIT Guwahati had produced the following graph related to the concept pertaining to carrying capacity ( Fig. ...

... Environmental Carrying Capacity (ECC) is a critical factor for urban environmental sustainability, as it determines the maximum number of people, species, and activities that the environment can sustain over a given period of time (Bhagwat and Devadas, 2021). If the carrying capacity of the environment is exceeded, the environment will suffer from a range of problems such as resource depletion, increase in climate change, environmental degradation, pollution and health risk, loss of biodiversity, destruction of ecosystem services and habitat (Arrow et al., 1995;Liu and Borthwick, 2011). ...
Globally, ecological overshoot has become more prevalent. Enhancing biocapacity has become critical to resolving ecological demand overshoot in sustainable urban development. However, most of the prior research has focused on minimizing environmental carrying capacity (ECC) while ignoring the potential of carbon footprint, population growth, and land cover (LULC). This research assessed the past and projected changes in bio-capacity and bio-productivity dynamics in Khulna City due to land use and land cover (LULC) transformations spanning from 2000 to 2035. Support Vector Machine algorithms were utilized for the classification of LULC, and LULC, bio-capacity and bio-productivity predictions were made using Cellular Automata-Artificial Neural Network models. Results revealed that built-up and cropland area expansion led to an increase in carbon emissions by 43,000 tons/year and bio-productive land by 1100 gha, while a decrease in bio-capacity from 0.09 gha to 0.06 gha occurred during 2000–2020. The prediction shows that by 2021, population growth and urban growth will exceed Khulna City's bio-capacity, and by 2035, bio-capacity (without built-up cover) will decrease to 0.00 gha. The R2 values (–0.67 and –0.91) indicate the strong negative influence of population growth and urbanization on the optimization capacity of soil surfaces. The study demonstrates that Khulna's present urban growth and population growth will result in irreversible ecological collapse, with dire consequences for humans in the near future. However, the findings facilitate the potential for the decision makers including policymakers, planners, and environmentalists to enhance local land use practices, thereby addressing CO2 emissions and their associated consequences meriting further study.
Dalam beberapa tahun belakangan ini, sektor pariwisata semakin menjadi perhatian beberapa kalangan, seperti dari pihak swasta dan pemerintah. Masyarakat di Indonesia pun sudah mulai turut serta mengambil andil dalam pengembangan sektor pariwisata di daerahnya masing-masing. Hal ini terjadi karena masyarakat mulai menyadari bahwa sektor pariwisata dianggap bisa menjadi sumber pendapatan daerah yang nantinya juga akan berkontribusi terhadap perkembangan ekonomi daerah tersebut. Selain itu, ada faktor lainnya yang membuat sektor pariwisata kini menjadi perhatian banyak pihak yaitu karena adanya perubahan pola pikir terhadap keberadaan sektor pariwisata.
Di awal pengembangan pariwisata, beberapa daerah masih memiliki pola pikir yang negatif terhadap pariwisata, seperti pariwisata cenderung identik dengan hal-hal yang negatif, seperti hiburan malam, pergaulan bebas, hedonisme, dan lain-lain sebagainya. Dampak dari pola pikir ini mengakibatkan sisi positif dari sektor pariwisata semakin melemah, seperti pemanfaatan Sumber Daya Alam (SDA) sebagai pertunjukkan, atraksi, serta pelestarian budaya. Namun sejak pariwisata menjadi salah satu sektor unggulan, keadaan itu pun mulai berubah total, yaitu pariwisata mulai membawa banyak manfaat seperti menjadi sumber pendapatan bagi daerah pariwisata tersebut.
