Effects of climate change on transport and their adaptation measuresRanga Sameera
The document discusses the effects of climate change on various modes of transportation and potential adaptation measures. It addresses how climate change may impact road, rail, water and air transportation through increased temperatures, more frequent droughts, sea level rise, extreme rainfall, and intense storms. Each section provides examples of impacts, such as flooding of roadways and rail lines, and suggests possible adaptations like improved drainage, using more durable materials, and developing vulnerability maps. The conclusion emphasizes that climate change represents a major issue and will significantly impact built transportation infrastructure unless adaptive responses are implemented.
The document provides an overview of findings from a climate risk and vulnerability assessment for the Nam Ngiep 1 hydropower project in Laos. It identifies the most significant climate change impacts as an increased potential for energy production but also a dramatic rise in spillway usage accelerating wear. Moderate impacts include reduced reservoir storage and water quality issues. Monitoring critical thresholds and preventative catchment measures are recommended, along with studies on adaptation opportunities.
This document summarizes VicRoads' climate change risk assessment and adaptation strategies. It identifies the greatest risk as the impact of sea level rise on coastal assets in eastern Victoria, which could result in road overtopping and damage to pavements and bridges. While impacts are predicted across the Victorian coast, the effects are likely to be most significant in eastern regions. The assessment adopts a conservative climate change scenario, consistent with other Australian organizations, to project more significant climate impacts by 2030, 2070 and 2100. Adaptation strategies will need to consider asset lifespans and evolve as new climate projections and data emerge.

Governments around the world are starting to mandate that government funded organizations such as universities and NRENs develop Climate Change Preparedness plans. This is in recognition that we are already committed to a 2C average temperature increase and given the lack of any international agreement on curbing GHG emissions we may be headed to a 6C global average temperature increase. More severe weather patterns are expected which will cause severe disruption to our energy and physical infrastructure. Resilient networks, new network architectures and tools such as distance education and remote collaborative research will be required by our universities and schools to survive and endure periods of such extreme weather. A well designed and thought out Climate Change Preparedness plan can also help higher-ed and NRENs increase their operational resiliency, as well as significantly reduce their current electrical energy costs. In addition a good Climate Change Preparedness plan can also be an excellent way for higher-ed and NRENs to reduce their existing GHG footprint.
Climate change preparedness plans are needed to adapt to a warming world with more severe weather. NRENs and higher education institutions should develop such plans aligned with national initiatives. Distance education is important for continuity during disasters. Preparedness plans involve risk analysis to identify vulnerable infrastructure and mitigation strategies. Reliability of the electrical grid is a major threat. Lessons from extreme weather show how distance education and robust networks are critical during disasters. Microgrids and renewable energy can increase reliability and lower costs and emissions.

This document discusses the resilience of electricity transmission grids in the face of climate change and increasing extreme weather events. It outlines several drivers that are influencing grid development over the next decades, including slow demand growth, high costs of building new lines, and tight capacity margins. Climate change is expected to increase the likelihood of weather-related outages and potential migrations that could impact demand. The document evaluates four pillars of grid resilience: redundant links, isolating outages, restoring services, and repairing/rebuilding infrastructure. It also discusses challenges to expanding grids to improve resilience.

The results will help local planners prioritize flood mitigation efforts.
Session 6: Scene-setting-Mainstreaming resilience in projects - Sophie Lavaud...OECD Environment
Indonesia is highly vulnerable to climate change risks such as sea level rise, landslides, floods and droughts due to its dense population and dependence on natural resources. Climate change impacts on infrastructure can lead to severe social and economic consequences by disrupting access to basic services. Mainstreaming climate resilience into infrastructure planning can help reduce these risks through fortifying infrastructure, increasing system capacities, and building in higher elevations. This requires assessing climate hazards and risks, adapting planning policies, technical standards, and financing strategies to account for future climate conditions. However, developing climate resilient infrastructure faces challenges from uncertainties around future climate impacts, a lack of climate information, and misaligned incentives across administrative cycles.
This document discusses climate change risks for infrastructure projects like railways. It uses the Konkan Railway Corporation Limited (KRCL) project in India as a case study. Some key points:
- KRCL connects two important ports but the terrain is extremely rugged with many rivers, landslides, and heavy rainfall, exposing it to climate risks.
- Past accidents on the railway have been caused by boulders and landslides during heavy rainfall events.
- KRCL has already spent over 280 crore rupees on additional safety works and plans to invest another 340 crore to reduce risks from boulders and landslides.
- Future climate projections for the region include increased annual rainfall and temperatures, making
This guidance manual provides a systematic approach to integrating climate change considerations into transport infrastructure design and management in Solomon Islands. It aims to reduce economic and social costs from climate impacts by making infrastructure more resilient. The manual is intended to be a practical resource for Ministry of Infrastructure Development staff in screening projects for climate risks, assessing key risks, developing adaptation options, and appraising options for integration into design and management. Considering climate change adaptation early in project development helps address risks cost-effectively.

SESSION VI: PLENARY –PILLARS FOR NATIONAL ADAPTATION PLANS
The session will examine a few case studies of how a particular issue of prime importance for a country can be the main entry point or pillar of the adaptation work, after which all other issues would then be considered. Three examples will be covered. Madagascar is a well-known centre of biological biodiversity. Addressing climate change through adaptation must consider the dynamics of this biodiversity including closely related stress factors such as poverty, pressure on land due to deforestation, shifting viability of the main cash crops when climatic conditions change, etc. Two other examples are on taking a regional approach to the assessment and development of adaptation responses in the context of hydro-energy. In other cases, a focus on community-based adaptation has been very successful, as is the case for Bangladesh.

The document introduces the IMCORE climate change project and provides an update on work being done in the Severn Estuary. IMCORE aims to promote sustainable approaches to reducing climate change impacts on coastal resources through developing adaptation strategies across North West Europe. For the Severn Estuary, activities include developing a science base through SECCRAG, reviewing corporate responses to climate change, scenario building for future climate conditions, and developing education materials. Preliminary findings show local authorities have key roles in climate change preparation and most have adopted strategies, but there is little sense of cohesion across the Severn Estuary. Future IMCORE work includes ongoing science reviews, partnership opportunities, and upcoming events.
How climate data can help address the climate challengeEsri UK
Climate change has already altered the weather we experience and the magnitude of impacts from extreme temperatures and rainfall. These impacts manifest locally and can cause human causalities and damage to infrastructure and natural systems. In future, some further climate change is now inevitable, but the rate and magnitude of change will depend on global greenhouse gas emissions. New data and tools to use the data are available to help plot a path through the climate and weather challenges, enabling organisations at all scales to adapt to the changing conditions.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Autumnal Weather Conditions
• Despite all the prep, performance will depend on the weather. Wet,
windy/stormy days have a very high impact
• New weather forecasting and EWATs in place to anticipate and
manage
• severity of the season depends on how many of those we get
• So far the weather has been benign but the forecast is generally for
an ‘active’ autumn
• Impact of storms is significant for performance as in autumn 2013

The UK Climate Change Projections
2009 anticipates that, by 2080 under the
medium emission scenarios, the UK
climate will change as follows:
•Mean daily maximum temperatures
(2080s relative to 1961-1990, medium
emissions) are projected to increase
across the UK. Increases in the summer
average are up to 5.4ºC (2.2 to 9.5ºC) in
parts of southern England
•Variations of summer and winter
precipitations of between -40% and +33%
respectively
Phase 1 – Examples of future climate change
• Sea level rise of between 12 and
76cm by 2095 (compared with a
1980-99 baseline)
• Changes in storm surge. For
example in the Bristol Channel
and Severn Estuary, an increase
in 50-yr surge return level of
around 0.8mm per year
• Increase in the number of
lightning days are projected for all
four seasons across the whole of
the UK

What are we doing about the climate
scenarios?
T1009 = Tomorrow’s Railway and
Climate Change Adaptation Programme
A RSSB funded research study
sponsored by the Technical Strategy
Leadership Group (TSLG)
T1009 explores the need to increase the
resilience of the GB railway in response
to anticipated changes in key climate
variables

Future climate change will impact the GB railway – as a whole system and its sub-
systems
The rail industry has commissioned T1009 to improve industry understanding of
these impacts and provide support tools for adaptation / resilience decisions
A system-wide approach is important when considering targeted and prioritised
investments
T1009 is considering the whole GB railway system and its global supply chains
Even a small change in average temperatures will have a significant impact on
the system
Some lessons – many – are relevant for the infrastructure ‘sector’ more widely
Why is this important?

1. What is the projected climatic change in the UK over the next 50
years?
2. What are the likely impacts of climate change and extreme weather
on the railway?
3. What actions can be taken by GB rail industry in response to these
potential impacts?
4. What are the proposed future actions, including 'quick wins' which
can be implemented over the next few years?
5. What are the requirements for additional decision support
frameworks, processes, and tools, to permit cost-effective action to
be taken?
Key questions that T1009 has been asked to clarify
28. /
There is a wide range of climate
change and extreme weather related
impacts that could potentially affect
the GB railway system, its
subsystems, and related assets.
Weather impact is currently estimated
to cost the industry 1.6 million delay
minutes a year, or about £50 million a
year (source: Network Rail Analysis
Report, September 2014).
Forecasting the next few days’
weather will be an increasing
challenge.

T1009 is delivering useful outputs for the rail industry. Organisations
which have engaged the most are likely to benefit the most
System of systems approach confirms the importance of
interdependencies and interfaces, some of which lie with
organisations outside of the rail industry
Consensus from other countries and asset managers is that GB railway
is an exemplar and is a leading example of good practice
A number of analogue countries have been identified:
France, Netherlands, Belgium, Germany and Denmark
There are no ‘silver bullets’ that other countries have!
Remaining challenge is how to make the information and research
accessible to all

Wind – actually the impact of wind upon trees, objects blown onto the line, especially OHLE
Tim Leighton – Network Rail General Manager, Western Route, Speaking on Maidenhead Multi-Disciplinary Flood Relief.
Earthworks monitoring
Improving resistance to flooding e.g. Pangdean sub-station
Big part of mitigation is Snow and Ice Treatment Trains (SITTs). There are currently 6 of these with another 4 on order due for delivery in time for winter 2015/16. They are used for brushing snow and ice off the third rail and for laying anti-icing agent on them. The 6 that are currently in service are centrally owned and deployed to the different Routes.
Resilience needs to be considered at system, as well as asset-level
Significance of zero derailments due to earthworks failures in 2013/14
Reducing the impact of flooding damage through the use of temporary dams, also make reference to raising signalling systems etc.
Weather forecasting is key to understand risk, and invoking contingency planning.
