Water resources include fresh water sources like surface water, groundwater, and frozen water that are useful for human activities. Only 3% of water on Earth is fresh water, with over two thirds frozen in glaciers and ice caps. The remaining fresh water is found mainly as groundwater or above ground. Natural fresh water sources include surface water, groundwater, and frozen water. Artificial fresh water can come from treated wastewater or desalinated seawater. Humans use fresh water for agriculture, industry, households, recreation, and the environment.
Water is the most precious gift of mother nature. Hydrology is the scientific study of the origin, occurrence, properties, distribution, and effects of water on the Earth’s surface, in the soil and in the underlying rocks, and also in the atmosphere. This module explain's the distribution of water in the global hydrosphere.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
Artificial Reefs by Kuddle Life Foundation - May 2024punit537210
Situated in Pondicherry, India, Kuddle Life Foundation is a charitable, non-profit and non-governmental organization (NGO) dedicated to improving the living standards of coastal communities and simultaneously placing a strong emphasis on the protection of marine ecosystems.
One of the key areas we work in is Artificial Reefs. This presentation captures our journey so far and our learnings. We hope you get as excited about marine conservation and artificial reefs as we are.

2. Water resources are natural resources of water that are potentially useful for
humans,[1] for example as a source of drinking water supply or irrigation water.
97% of the water on the Earth is salt water and only three percent is fresh
water; slightly over two thirds of this is frozen in glaciers and polar ice
caps.[2] The remaining unfrozen freshwater is found mainly as groundwater,
with only a small fraction present above ground or in the air.
3. Natural sources of fresh water include surface water, under river
flow, groundwater
and frozen water. Artificial sources of fresh water can include treated
wastewater
(wastewater reuse) and desalinated seawater. Human uses of water
resources include agricultural
, industrial, household, recreational and environmental activities.

6. WATERBUDGET:-
Water budgeting is a principal activity for proper management of water
resources. Actually ‘waterbudget’ is an accounting of water inputs, outputs
and storage of water e.g.in lithosphere, atmosphere and oceans. Hence,
Water Budget means – the balance between the available water in the
country and the water under use. Hence, it is balance between the accessible
water and the water under utilization.The solar radiations evaporate water
from oceans and land and transpiration of water from plants introduce
moisture into the atmosphere which returns to earth as precipitation. It is
estimated that about 525100 cubic kms water introduce into the atmosphere
and from this about 21.6% water vapors comes to earth as precipitation over
land surface. The water budget calculation includes the different mechanism
used in water cycle e.g. precipitation, evaporation, evapotranspiration,
surface and subsurface flow. The table presents the Annual water budget of
planet earth.
8. It is evident from Table: 2 that world’s oceans impart about 4,52,600 cubic
kms water annually to atmosphere while get only 4,11,600 cubic kms as
precipitation. However, this deficit is balanced by 41,000 cubic kms of surface
and subsurface runoff, which they receive. This excess water ultimately flows
back to oceans under the influence of gravity (Roggers, 1991). Moreover, the
amount of water presents in oceans, on land, groundwater and water present
in atmosphere in vapors form etc. are in a state of dynamic equilibrium.
