This document discusses how global climate change and human activities are altering coastal ecosystems by intensifying eutrophication. Climate change is causing detrimental effects through changes in temperature, salinity, winds, storms, and sea levels. These changes increase stratification in water columns and the vulnerability of coastal habitats. Additionally, human industrialization and farming are producing large quantities of reactive nitrogen and phosphorus that promote eutrophication when they reach coastal waters through rivers and runoff. The Mississippi River watershed example shows how nutrient overloading from landscape changes can continuously expose large coastal ecosystems to eutrophication. There is a need to reduce excess nutrient loads to prevent further water quality declines.

CLIMATE change affects the components of water cycle such as evaporation, precipitation and evapotranspiration and thus results in large-scale alteration in water present in glaciers, rivers, lakes, oceans, etc. The effects of cli-mate change on subsurface water relates to the changes in its recharge and discharge rates plus changes in quantity and quality of water in aquifers. Climate change refers to the long-term changes in the components of climate such as temperature, precipitation, evapotranspiration, etc. The major cause of climate change is the rising level of greenhouse gases (GHGs) in the atmosphere such as CO2, CH4, N2O, water vapour, ozone and chlorofluorocarbon. These GHGs absorb 95% of the longwave back radiations emitted from the surface, thus making the Earth warmer. Except CO2, the effects of other GHGs are minor because of their low concentration and also because of low residence times (e.g. water vapour and methane). The rise in CO2 level causing global warming was first proposed by Svante Arrhenius, a Swedish scientist in 1896 and now it is a widely accepted fact that the concentration of CO2 is the primary regulator of temperature on the Earth and leads to global warming.

Adaptation to global change must include prudent management of groundwater as a renewable, but slow-feedback resource in most cases. Groundwater storage is already over-tapped in many regions, yet available subsurface storage may be a key to meeting the combined demands of agriculture, industry, municipal and domestic water supply, and ecosystems during times of shortage.

Climate change ,adaptation and mitigation in fisheriesSWAGATIKA SAHOO
Climate change impacts on aquatic and marine ecosystems and associated livelihoods are growing, and the purpose of this circular is to provide a brief overview of potential impacts and details of ongoing and completed adaptation activities. Sharing examples will aid planning and development of adaptation in fisheries and aquaculture, and this compilation is intended to provide a starting point for planners, policy-makers, and practitioners who are involved in sectors related to fisheries and aquaculture around the globe. This introduction provides an overview of climate change impacts on fisheries and aquaculture. The presentation reviews potential mitigation and adaptation options for fisheries and aquaculture at various scales. This is followed by an overview of selected adaptation activities at various scales to demonstrate the types of activities underway or completed around the world, primarily in developing countries. This is not a comprehensive review of adaptation actions – there are other resources that provide more in-depth reviews of adaptation. However, this circular aims to provide examples of the kinds of adaptation activities specifically addressing fisheries and/or aquaculture.

Modelling climate change impacts on nutrients and primary production in coast...Marco Pesce
There is high confidence that the anthropogenic increase of atmospheric greenhouse gases (GHGs) is causing modifications in the Earth's climate. Coastal waterbodies such as estuaries, bays and lagoons are among those most affected by the ongoing changes in climate. Being located at the land-sea interface, such waterbodies are subjected to the combined changes in the physical-chemical processes of atmosphere, upstream land and coastal waters. Particularly, climate change is expected to alter phytoplankton communities by changing their environmental drivers (especially climate-related), thus exacerbating the symptoms of eutrophication events, such as hypoxia, harmful algal blooms (HAB) and loss of habitat. A better understanding of the links between climate related drivers and phytoplankton is therefore necessary for projecting climate change impacts on aquatic ecosystems. Here we present the case study of the Zero river basin in Italy, one of the main contributors of freshwater and nutrient to the salt-marsh Palude di Cona, a coastal water body belonging to the lagoon of Venice. To project the impacts of climate change on freshwater inputs, nutrient loadings and their effects on the phytoplankton community of the receiving waterbody, we formulated and applied an integrated modelling approach made of: climate simulations derived by coupling a General Circulation Model (GCM) and a Regional Climate Model (RCM) under alternative emission scenarios, the hydrological model Soil and Water Assessment Tool (SWAT) and the ecological model AQUATOX. Climate projections point out an increase of precipitations in the winter period and a decrease in the summer months, while temperature shows a significant increase over the whole year. Water discharge and nutrient loads simulated by SWAT show a tendency to increase (decrease) in the winter (summer) period. AQUATOX projects changes in the concentration of nutrients in the salt-marsh Palude di Cona, and variations in the biomass and species of the phytoplankton community.

Today Water, Climate & Energy is related to every
aspect of human life: social equity, ecosystem & economic
sustainability. Water is used to generate energy; energy is used to
provide water. Water, energy and climate are inextricably linked,
which is of great concern and increasing importance for future.
Global primary energy demand is projected to increase by just
over 50% between now and 2030, which can be met by more
prod., consuming water & other natural resources, adopting
better technologies and also encouraging changes in energy use
pattern. Water withdrawals are predicted to increase by 50% by
2025 in developing countries and 18% in developed countries.
The worst fallouts of the climate change are shrinking of water
resources. Climate change acts as an amplifier of the already
intense competition over water & energy sources.
Solving the interlinked challenges of water, energy & climate in
a sustainable manner is one of the fundamental goals of the
present generation. To achieve this, related research and
knowledge should be expanded and discussed with in technical
circles. Technology, innovation a sense of shared responsibility
and political will are factors that bring real solutions to keep pace
with increasing needs. Resolving growing issues will require
better and integrated policy frameworks & political engagement
for all stakeholders within and across water sheds. Leadership
from all parts of society is must for change to happen.

The climate system is a complex, interactive system consisting of the atmosphere, land surface, snow and ice, oceans and other bodies of water, and living things.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Introduction
Global climate change and human activities are
altering the ecological condition of estuarine and
coastal ecosystems by intensifying problems such as
eutrophication
4. Global climate change impacts
Changes in the climate system will cause detrimental
effects on:
a) ecosystem structure and function
b) trophic interactions
c) habitat ranges
d) migration patterns
5.
6. Global climate change impacts
Effects on temperature and salinity would increase
water stratification
a) Higher surface water temperatures tend to
strengthen pycnoclines – less vertical water
circulation
b) Increase in freshwater runoff would help increase
concentration of nutrients in the surface and
decrease surface water salinity
7.
8. Global climate change impacts
Regional wind patterns – will cause changes in
circulation and mixing
Tropical storms and hurricanes – increased
vulnerability of coastal habitats and potential effects
on stratification
Enhanced hydrological cycle – more water,
sediments and nutrients reaching the coastal zone
which are likely to enhance eutrophication
9. Global climate change impacts
Sea level rise – Coastal wetlands are further affected
by increasing erosion, flooding and saltwater
intrusion and may reduce the services they provide
as ecosystems.
10. Eutrophication and human activities
Related to excessive loading of nutrients – stimulates
phytoplankton growth
Anthropogenic activities (industrialization and
mechanized farming) produce huge quantities of
reactive nitrogen and phosphorus which promote
eutrophication processes.
11. Case history
Mississippi River watershed and Gulf of Mexico
a) Examples of continental – scale ecosystems that
have suffered from landscape changes and are
constantly exposed to increasing nutrient loads
14. Summary
Coastal water quality is declining due to human
activities (global climate, hydrological cycles,
landscapes and the flux of nutrients such as nitrogen
and phosphorus)
These excess nutrients are finding their way to
coastal zones in increasing amounts and are
predicted to increase the incidence and severity of
eutrophication and hypoxic water formation.
There has to be a reduction of nutrient loads to
prevent further degradation
