Scenario planning reflects land use planning for buildings
and land use. However, its limitation is that it cannot be applied to land use planning
in hazardous areas. This study aims to analyze and compare scenario planning results
in light of climate change risks and future development scenarios. An alternative
analysis was conducted in Myeongji-dong, Gangseo-gu, Busan where urban development
has increased rapidly.
The study results indicate that (1) scenario planning can be used to show changes
in risk by use area according to climate change and that (2) as urban development
scenarios and climate change risks can be integrated; comparative analyses of alternatives
can reveal their combined impact.

Page No. 10-22
In the context of natural resource management, watershed
restoration and integrated watershed development, watershed prioritization has obtained
immense importance. In this study, morphometric parameters and land use/ land cover
analysis have been considered for prioritization of 14 sub-watersheds in South Sikkim
Himalaya. At the context of micro level natural resource management, soil and water
conservation and runoff concentration, quantitative analysis of morphometric parameters
and land use/ land cover have been found of great utility. In this study we have
thoroughly analysed linear, relief and shape aspects of morphometric parameters
and land use land cover analysis in 14 sub- watersheds of South Sikkim Himalaya
and also their prioritization for overall management. First, the ranking has been
done to every single parameter in relation to slope instability, then the ranking
values for all the linear, relief and shape parameters of each sub-watersheds have
been added up to find composite score. Composite score of each sub-watershed has
been divided by 13(parameters) and finally we get compound score of every sub-watershed.
Based on compound value of these parameters, the sub- watersheds have been assigned
final priority rank.
The results achieved from morphometric parameters and land use/ land cover analysis
have been correlated to get the common sub-watershed priority falling under each
priority. The correlation shows that sub-watersheds ESW1 and ESW2 fall under high
priority and ESSW1 falls under low priority based on both parameters. Rest of the
watersheds reveal slight correlation and differ in their priority under morphometric
parameters and land use/land cover analysis. According the final prioritized map,
conservation measures should first be applied to sub-watersheds ESW1 and ESW2 and
then to the other sub-watersheds depending upon their priority.

In every earthquake and tsunami event, an effort to evacuate
to a safe place is the right choice. This is because after the earthquake, the damage
caused is usually quite massive and there is little time to react in an attempt
to evacuate to a safe place from the reach of the tsunami waves. Watulimo district
is one of the districts in Trenggalek Regency which is located in coastal area and
tsunami prone zone. The location of community settlements near the coast faced a
risk of being affected by the tsunami disaster. The high density of settlements
can cause economic losses in the surrounding community and cause loss of lives in
the event of a tsunami disaster. There is no evacuation route and tsunami disaster
management plan is also an urgency for the needs of evacuation route directives.
This study aims to identify and determine the location of the evacuation point (shelter)
as well as compile the direction of the tsunami disaster evacuation route in the
Watulimo District Coastal Area. Determination of temporary evacuation points is
done by scoring and weighting techniques. Evacuation routes are analyzed using network
analysis considering closest distance to the evacuation point. The results of the
analysis of the evacuation route produce maps and directions for tsunami disaster
evacuation routes in three coastal villages of Watulimo District Coastal Area.

Transboundary disaster governance between India and
Nepal - A perspective study on Kosi basin about risk governance dealing policies
and communities

Page No. 32-39
India and Nepal both being part of the same Himalayan
ecosystem, share benefits of natural resources such as water and energy. Similarly,
they also face challenges of water induced disasters like floods, landslides and
soil erosion, which affect both the countries and have become prime concern for
the administration on both sides. Therefore, both the countries have decided to
tackle the wrath of nature jointly. Kosi river basin is one such example between
two countries which has set a high standard of mature regional cooperation for more
than a century for flood management. However, the cooperation between these countries
is at a very high ministerial level for policy makers and technical committee’s
set-up to provide day to day management solutions.
However, transboundary communities on both sides are not part of decision making
and get very less scope for participation to raise their concerns and voices. It
is evident that both the countries have managed to have expertise on various subjects
such as early warning, data management, infrastructure management, satellite applications
in disaster management (DM), disaster rescue forces and administrative planning
for disaster risk reduction (DRR) which is exemplary. But the shift envisaged from
response mode to disaster risk reduction is still far away, the benefits of the
success are still not reaching the communities on both the sides, as there is no
interaction between the communities and no mechanism is available to share the resources.
New federalism policy in Nepal and Panchayat system in India can give lessons to
include disaster risk reduction into governance on both sides. An urgent need for
framework on disaster risk reduction on basin level is felt necessary for the communities
between transboundary nations. This study attempts to understand the existing disaster
policies and practices across the border governing disasters and also the disaster
risk reduction processes. It is imperative to see how community perceives the risks
across the border and how can community be a part of decision-making process.

Flash flood risk zone map development for THANH HÓA,
NGHỆ AN and HÀ TĨNH provinces, Vietnam
Huynh Thi Lan Huong and Luong Huu Dzung
Page No. 40-51
In terms of disaster preparedness planning, research
on the development of flash flood risk zone maps is essential and many studies have
been undertaken globally including Viet Nam. In this study, we propose a method
for developing flash flood risk zone maps based on seven components: rainfall, basin
slope, river slope, soil (soil erosion risk, forest cover (protective capacity of
forest cover), land use (water storage capacity) and specific peak flow. This method
is applied to the study area of Thanh Hóa, Nghệ An and Hà Tĩnh provinces, Viet Nam.
The produced maps show that high risk areas are distributed along high mountain
ranges whereas lower slopes are lower risk areas.

Page No. 52-58
The Jammu and Kashmir is one of the flood-prone states
of Indian Himalayas. In 2014 floods, approximately 268 people died and 168004 houses
were damaged. Pulwama, Srinagar, and Bandipora districts were severely affected
with 102, 100 and 148 sq km respectively submerged in floods. In this research work
a flood zonation map is created along the river Jhelum using ArcMap 10.3. The regions
were classified as high risk, medium risk and low risk areas. The area under these
zones is also calculated. A hybrid system of wireless sensors and machine learning
approach is proposed to forecast the water level of river Jhelum at Sangam area
of Anantnag. This hybrid system showed the high accuracy with Average deviation
of 0.78 for daily predictions and 0.2 for hourly predictions.

Page No. 59-71
It is well known that the occurrence of one natural hazard
can create cascading effect by triggering one or more other natural hazards, making
the task of disaster management immensely critical. The information regarding the
proneness to multiple hazards in a region could be useful in planning resource allocation.
In this context, the objective of this study is to investigate the spatial variation
of multi-hazard susceptibility across India. The station data of earthquake zone
factors and basic wind speeds at different locations provided by the Indian Standard
codes and the India Meteorological department (IMD) along with the information provided
by the state disaster management authorities regarding proneness of floods and landslides
are utilized for the purpose. Combining this information, the multi-hazard susceptibility
is evaluated at different locations across the country by means of a Multi-Hazard
Score (MHS).
Finally, a map is prepared which visually presents the variation of multi-hazard
susceptibility across India. Such maps are expected to be useful in devising suitable
multipronged disaster management approaches for any other country following the
methodology which is explained through the study of the Indian subcontinent.

Page No. 72-75
Forest fire has long been one of the serious natural
risks in China’s forested regions, especially in urban-forest landscape which is
a serious hazard to human lives and infrastructure. The frequency and burnt area
in spatial distribution of these fires vary over time and across the forested cities
in Zhejiang province, Southeast China. In this study, the occurrence and distribution
of 19983 forest fires during 1988–2017 in the province were collected and investigated.
The results indicated that the spatial and temporal distribution of forest fire
occurrence and burnt forest area varied significantly by year and region from 1988
to 2017.
Further, the results also showed that the forest areas in the subtropical region
of southeastern China are subjected to forest fire hazards and are the key prevention
region under global climate change in future decades.
