Today's rapid development of remote sensing technology has made it possible to quickly acquire urban thermal environment information over a wide area with high resolution. It has become an indispensable technology for monitoring urban thermal environment. However, in recent years, there has been a rapid increase in the number of papers on urban thermal environment and heat island research by researchers in the field of remote sensing who do not have enough background on urban thermal environment, meteorology, geography, etc. But there are some unfortunate papers that seem to have been written without knowledge of important backgrounds.

In Finland, there are plenty freshwater lakes where seasonal lake environmental changes were recorded as annually laminated deposits. We surveys diatom fossil assemblages at the following three lakes in the central Finland to reconstruct high resolution environmental histories using annually laminate time setting of the deposits.
Our target was about these 2000 years to presume anthropogenic impacts and global climatic impacts during the Roman Warm Period, the Great Migration Period, the Medieval Warm Period, the Little Ice Age and the Global Warming.

Downslope movements of 12 stones (10–27 cm in diameter) were determined from time-series images over 21 years on a Japanese alpine debris slope. Frost heave occurred 24–85 times/a with an annual maximum amount of 1.8–5.6 cm. Stones moved downslope at 4–16 cm/a, the velocity correlating with the stone size. Extrapolation suggests that needle ice can transport stones with a diameter of 30 cm or more. Both annual mean air/soil temperatures and frost heave activity slightly increased during 21 years. Climatic warming may have raised the frequency of needle ice by shortening the snow-covered period.

Realistic regional geography begins with landscape analysis of one’s local area. In landscape analysis, a landscape can be understood as a projection of the local environment onto the surface of the earth. In order to systematically interpret landscapes that reflect the daily lives of people in a region, students have to first discover the interesting phenomena in the landscape, and then identify the natural environment and socio-economic environment, historical and cultural environment, etc. that characterize such phenomena. Ultimately, they should identify the character of the region through the interrelationship between the phenomena and various environments.

Sri Lanka is a fertile tropical country with a wide variety of crops and farming depend on two main seasons called yala and maha compatible with rain pattern. Agriculture in Nuwara Eliya threats by issues such as less crop production, unexpected environmental changes, soil degradation pest, and diseases. Also, wildlife conflict plays a big role in the loss of production due to intense wildlife conflicts. When we consider agriculture in the area, we can see Human-wildlife conflict (HWC) plays a significant role in the activities such as conservation and livelihood activities. Also, should address other important factors in equal importance. In the study, we try to focus on and investigate the grass root factors causing HWC in the Nuwara Eliya DS division. When we consider the out Outcomes of the study, we manage to identify the list of animals that contribute to the wildlife conflict in the area, manage to estimate economic loss from the animals, get a better understanding of the factors which affect conflict, make better understanding among people’s perception about human-wildlife conflict, create robust data set for the management authorities (department of agriculture, department of wildlife, etc.). The result can be used to mitigate the conflict and identify possibilities to coexist with wildlife (win-win solutions for both humans & wildlife.

The author is a seismologist who has been studying the Great Kanto Earthquake of 1923 for 30 years. I have researched the epicenter, tremors, and damage, and have conducted field surveys in Kanagawa Prefecture and the 23 wards of Tokyo over the last ten years. According to the results, the damage spread to nine prefectures in the Kanto and Chubu regions, and the number of dead and missing people was 105,000, about five times that of the Great East Japan Earthquake. The total direct damage was about 5.5 billion yen. It was truly an earthquake that threatened the survival of the nation. In particular, the number of deaths in Tokyo City and Kanagawa Prefecture was 69,000 and 32,000 respectively. In this presentation, I will first describe what happened in Kanagawa Prefecture, which was directly above the epicenter, and then consider why Tokyo, which was outside the epicenter area, became the most devastated area. Furthermore, how did the people of Tokyo recover? And finally, we will consider why Tokyo, which should have been improved to be a city that is resistant to earthquakes and fires, should now be afraid of the threat of the next earthquake.

An approach of dynamic regional geography was introduced on the regional geography study of the current National Curriculum Standards. On this type of regional geography study, the acquisition of geographical knowledge was emphasized as well as the acquisition of methods for understanding regional characteristics. While the emphasis on geographical competencies in addition to knowledge is commendable, there are many issues to be addressed regarding the specific content of regional geography study. For example, it is necessary to reexamine the division of region and the arrangement of study regions from the viewpoint of the degree of difficulty in acquiring regional characteristics.

Travel writing has been an integral part of geography since the time of Ptolemy. Travel writing research is also making progress in the fields of literary studies and criticism. In this report, a collection of essays with photographs published in the 1980s and 1990s by photographer Takeyoshi Tanuma is interpreted as a travelogue. The countries visited, the years of visit and publication, and the photographs were analyzed from a chronological perspective. As in school textbooks, the essays are compiled in a sequence in which the descriptions of specific countries visited are grouped by world region, and each region is traced on a world map with a single stroke.

A hundred years have passed since the Great Kanto Earthquake of 1923, and the need for earthquake disaster prevention to prepare for the next Tokyo metropolitan earthquake has been pointed out. It has been pointed out that if an earthquake disaster were to occur in the capital, where the unipolar concentration has progressed excessively, the impact would spread throughout Japan, leading to a "national crisis." There is no doubt that the lessons of the Great Kanto Earthquake are important when considering the future of Tokyo and Japan.
This symposium would like to discuss the following points.
(1) Learn the lessons of the Great Kanto Earthquake from a bird's-eye view from the keynote speech.
(2) Reconsider the lessons of the earthquake as a modern problem.
(3) Know how geography has contributed to earthquake research and disaster prevention promotion in the Tokyo metropolitan area over the past 100 years.
(4) Organize the issues of earthquake disaster prevention and the role of geography from a geographical point of view.
(5) Search for hints on how to make use of the lessons of the Great Kanto Earthquake in ``subjective learning'' in ``geography education for building a sustainable society.''

Humans have historically used mercury for a variety of purposes, however, the massive use of mercury since the modern period has caused global biological and environmental pollution. For this reason, an international treaty, "the Minamata Convention on Mercury", entered into force in 2017, which strictly restricts the development and use of mercury. However, mercury continues to be released into the environment through human activities. The largest source of mercury is "Artisanal and Small-Scale Gold Mining (ASGM)", which uses mercury to adsorb and accumulate (amalgamate) gold. The gold is recovered by heating and vaporizing the mercury from the amalgamate.
In Indonesia, which is rich in various subsurface resources, ASGM has been practiced on several islands and the country is one of the world's largest mercury emitters. Our research project (JSPS No. 19H04334) has studied the present situation of ASGM in the western part of Sumbawa Island and its effects on workers and the surrounding environment. In the process, we found that ASGM on Lombok Island has different characteristics from that on Sumbawa Island, so we conducted a new survey on Lombok Island as well.
In December 2022, we visited ASGM-related sites in the central and southern parts of Lombok Island, observed the local conditions, interviewed people engaged in ASGM, and collected samples. Samples were collected from tailings and wastewater produced by ASGM, and water that is used for ASGM as background.
In the study area, many ASGM practitioners engaged in it on a very small scale as a side job, and these workers had generally started ASGM within 10 years. It was found that a regional network has been formed among ASGM practitioners and a division of labor was established among them. Many of the very small-scale ASGM practitioners purchased rocks from those who were in charge of the process from procurement of raw stones to crushing and milling. Some of them also sold the tailings produced by ASGM to larger-scale ASGM operators. The spatial scale of such a network exceeded approximately 40 km in linear distance.
From the viewpoint of environmental pollution, such a regional network implies that the pollution source is moving and spreading over a wide area. Therefore, it concerns that pollution is occurring over a wide area. Even if the scale of contamination at each site is not large, groundwater contamination is likely to be occurring in many areas, as many of the ASGM effluents infiltrate into the ground. In addition, in a coastal area, wastewater is discharged directly into the sea, which may lead to marine environment pollution, as in the case of Minamata Bay.
On the other hand, some ASGM practitioners have introduced the Borax method. Although the Borax method used in the study area is not sophisticated, it does not use mercury and can recover the gold of higher purity. Therefore, they have expectations for the Borax method.

The provision of spatial information using the Web by National Mapping Organization is progressing in countries around the world, and there are Web map sites similar to GSI Maps. Since map images similar to the paper-based Topographic Map are also provided, it is highly useful for learning. An analysis of the results of presentation-style classes using this system showed that learning effects equivalent to those using GSI Maps were obtained.
