Role of UN in protection of Global Environment.

The United Nations (UN) plays a significant role in the protection of the global environment through various initiatives and frameworks. Here are some key aspects of the UN's involvement in environmental protection:

1. International Environmental Conventions: The UN serves as a platform for negotiating and implementing international environmental agreements, also known as conventions. Examples include the United Nations Framework Convention on Climate Change (UNFCCC), the Convention on Biological Diversity (CBD), and the United Nations Convention to Combat Desertification (UNCCD). These conventions provide a framework for countries to collaborate and address global environmental challenges.

2. Sustainable Development Goals (SDGs): The UN formulated the 2030 Agenda for Sustainable Development, which includes 17 Sustainable Development Goals (SDGs). These goals cover a wide range of issues, including poverty, health, education, and the environment. SDG 13 specifically focuses on climate action, while other goals, such as SDG 14 (Life Below Water) and SDG 15 (Life on Land), address biodiversity conservation and sustainable resource management.

3. United Nations Environment Programme (UNEP): The UNEP is the leading environmental authority within the UN system. It coordinates global efforts to address environmental issues and provides guidance and support to governments and stakeholders. The UNEP facilitates scientific research, policy development, capacity-building, and the implementation of environmental projects worldwide.

4. Intergovernmental Panel on Climate Change (IPCC): The IPCC is jointly established by the World Meteorological Organization (WMO) and the UNEP. It assesses the scientific, technical, and socioeconomic aspects of climate change and provides policymakers with objective and evidence-based information. The IPCC's reports have been instrumental in shaping global climate policies and actions.

5. Green Climate Fund (GCF): The GCF was established by the UNFCCC to support developing countries in their efforts to mitigate and adapt to climate change. It provides financial resources for climate projects and initiatives, assisting developing nations in implementing low-carbon and climate-resilient measures.

6. Environmental Advocacy and Awareness: The UN raises awareness about environmental issues and promotes sustainable practices through campaigns and initiatives. Events like World Environment Day and the UN Climate Action Summit serve as platforms for highlighting the importance of environmental protection and mobilizing action at the global, national, and local levels.

7. Partnerships and Collaborations: The UN collaborates with governments, international organizations, civil society, and the private sector to address environmental challenges collectively. Partnerships such as the Global Environment Facility (GEF) and the Sustainable Development Solutions Network (SDSN) bring together diverse stakeholders to support environmental initiatives and promote sustainable development.

Through its various agencies, programs, and initiatives, the UN fosters international cooperation, knowledge sharing, and policy development to protect the global environment. However, it's important to note that the success of these efforts relies on the commitment and actions of member states, non-governmental organizations, and individuals worldwide.

Groundwater – Porosity and Permeability

Groundwater refers to the water that resides beneath the Earth's surface in the pores and crevices of rock, sediment, and soil. Two key properties that influence the movement and storage of groundwater are porosity and permeability: 1. Porosity: - Definition: Porosity refers to the volume percentage of void spaces (pores or openings) in a geological material, such as soil or rock. - Role: Porosity determines how much water a subsurface material can hold. It is a measure of the material's capacity to store water. - Factors: Porosity is influenced by the size and arrangement of particles within the material. Highly porous materials have more void spaces, while less porous materials have fewer. - Units: Porosity is expressed as a percentage, with 0% indicating complete solidity (no pore spaces) and 100% indicating complete void space. 2. Permeability: - Definition: Permeability refers to the ability of a geological material to transmit fluids, such as water. It meas

Ground Water

Groundwater Terminology, Concepts, and Facts Key Terms Aquifer: A geological formation that can store and transmit significant quantities of water. Water Table: The upper surface of the saturated zone in an aquifer. Recharge: The process of replenishing groundwater through precipitation or other sources. Discharge: The process of groundwater flowing out of an aquifer, typically into surface water bodies or through wells. Hydraulic Gradient: The slope of the water table. Darcy's Law: A law that describes the flow of groundwater through porous media. Permeability: The ability of a material to transmit water. Porosity: The amount of void space in a material. Concepts Groundwater Flow: Groundwater moves from areas of higher hydraulic head to areas of lower hydraulic head. Groundwater Contamination: The introduction of pollutants into groundwater. Groundwater Depletion: The excessive extraction of groundwater, leading to a decline in water table levels. Saltwater Intrusion:

Artisan Wells Basins

Artisan Wells and Basins Artesian wells are a type of well that harnesses the natural pressure of water trapped underground to force water to the surface without pumping. This phenomenon occurs in specific geological formations known as artesian basins . Key Terminologies and Concepts Aquifer: A geological formation that can store and transmit water. It is typically made up of porous rocks or sediments like sandstone or gravel. Confined Aquifer: An aquifer that is sandwiched between two impermeable layers (like clay or shale) that prevent water from escaping. Artesian Basin: A geological structure where a confined aquifer is tilted and has a recharge area at a higher elevation than the discharge area. This creates a pressure gradient that forces water to flow upwards. Potentiometric Surface: The theoretical level to which water would rise in a well drilled into an artesian aquifer if there were no restrictions. It is determined by the pressure head in the aquifer. Flowing Artesian

Watershed. Catchment. Basin

A watershed, also known as a river basin or drainage basin, is a fundamental concept in geohydrology and hydrology. It refers to a specific geographic area or region of land where all the surface water, including rainfall, snowmelt, and runoff, drains into a common outlet, such as a river, lake, or ocean. Here's an explanation of each term: 1. Watershed: A watershed is essentially a natural hydrological unit defined by the topography of the land. It represents the entire area from which all precipitation and surface water flow eventually gathers at a single point. This point is typically where the main river or stream within the watershed exits into a larger body of water, such as an ocean. Watersheds come in various sizes, from small ones that encompass a few square miles to enormous ones that cover entire continents. 2. River/Drainage Basin: A river basin or drainage basin is another way to describe a watershed. It's the land area that collects and channels water into a river

Discrete Detectors and Scanning mirrors Across the track scanner Whisk broom scanner.

Multispectral Imaging Using Discrete Detectors and Scanning Mirrors (Across-Track Scanner or Whisk Broom Scanner) Multispectral Imaging: This technique involves capturing images of the Earth's surface using multiple sensors that are sensitive to different wavelengths of electromagnetic radiation. This allows for the identification of various features and materials based on their spectral signatures. Discrete Detectors: These are individual sensors that are arranged in a linear or array configuration. Each detector is responsible for measuring the radiation within a specific wavelength band. Scanning Mirrors: These are optical components that are used to deflect the incoming radiation onto the discrete detectors. By moving the mirrors, the sensor can scan across the scene, capturing data from different points. Across-Track Scanner or Whisk Broom Scanner: This refers to the scanning mechanism where the mirror moves perpendicular to the direction of flight. This allows for t
