environment, environmental thought, early environmental thinking, environmentalism, man and environment relationship and human-ecological adaptations

The environment means everything around us that affects living things, including humans.

Biotic components – Living things like plants, animals, and humans.
Abiotic components – Non-living things like air, water, soil, climate, and landforms.
Built / Cultural Environment – Things created by humans such as cities, roads, dams, and farms.

👉 In simple words:
Environment = Nature + Living things + Human-made surroundings.

Environmental Thought

Environmental thought means ideas about how humans and nature are connected. These ideas changed over time.

Major Theories

1. Environmental Determinism

Says nature controls humans.
Example: People in cold areas wear warm clothes and build strong houses.

2. Possibilism

Says nature gives limits, but humans can choose how to live.
Example: Desert areas have less water, but humans build canals and irrigation.

3. Neo-determinism (Stop-and-Go Determinism)

Says humans can develop using nature but must respect environmental limits.
Example: Excess industrialization causes climate change.

Early Environmental Thinking

People have been thinking about human-nature relationships since ancient times.

Ideas

Hippocrates – Said climate affects human health and behavior.
Ibn Khaldun – Linked climate with culture and lifestyle.
Ancient conservation ideas – Religious beliefs protected nature (like protecting trees and animals).

👉 Early scholars understood that human life depends on the environment.

Environmentalism

Environmentalism is a movement to protect nature and reduce environmental damage.

Ecocentrism (Deep Ecology) – Nature is important by itself, not just for humans.
Technocentrism – Technology and science can solve environmental problems.
Sustainability – Using resources carefully so future generations can also use them.
Environmental Justice – Fair distribution of environmental benefits and problems among people.

👉 Modern environmentalism focuses on climate change, pollution control, and biodiversity conservation.

Man–Environment Relationship

This explains how humans and nature affect each other.

Two-Way Interaction –
- Environment influences humans (climate, resources).
- Humans change the environment (urbanization, agriculture, industries).
Cultural Landscape –
Natural land changed by human activities.
Example: Cities, farmland, and transport networks.

👉 Today, the main concern is maintaining balance between development and nature.

Human-Ecological Adaptations

It means how humans adjust their lifestyle and technology to live in different environments.

✅ Types of Adaptation

Physiological / Behavioral Adaptation
- Changes in clothing, food, and housing based on climate.
- Example: Eskimos (Inuit) build igloos in polar regions.
Cultural / Technological Adaptation
- Humans modify nature to make living easier.
- Example:
  - Terrace farming in mountains
  - Air conditioning in hot regions
  - Greenhouse farming
Cultural Ecology
- Study of how culture and environment influence each other.

Environmental Geography studies how humans and nature interact across space and time.

👉 Main ideas:

Environment includes natural and human-made surroundings.
Environmental thought explains different views about human-nature relationships.
Environmentalism promotes protection of nature.
Humans both depend on and change the environment.
Human societies adapt to environmental conditions using culture and technology.

Supervised Classification

Image Classification in Remote Sensing Image classification in remote sensing involves categorizing pixels in an image into thematic classes to produce a map. This process is essential for land use and land cover mapping, environmental studies, and resource management. The two primary methods for classification are Supervised and Unsupervised Classification . Here's a breakdown of these methods and the key stages of image classification. 1. Types of Classification Supervised Classification In supervised classification, the analyst manually defines classes of interest (known as information classes ), such as "water," "urban," or "vegetation," and identifies training areas —sections of the image that are representative of these classes. Using these training areas, the algorithm learns the spectral characteristics of each class and applies them to classify the entire image. When to Use Supervised Classification: - You have prior knowledge about the c...

Lidar

LiDAR (Light Detection and Ranging) is an active remote sensing technology that measures distances by illuminating a target with laser pulses and analyzing the time it takes for the reflected light to return. Unlike passive systems (e.g., cameras, multispectral sensors), LiDAR provides its own energy source (laser), allowing it to operate both day and night and even penetrate through vegetation canopies . 🔹 How LiDAR Works (Step-by-Step Process) Laser Pulse Emission The system emits rapid, short pulses of laser light (commonly in the near-infrared wavelength, 1064 nm ). Some systems emit up to hundreds of thousands of pulses per second . Interaction with Target Surface The laser beam strikes objects such as vegetation, buildings, or bare ground. Depending on the object's structure, part of the pulse may scatter or reflect. Return Signal Detection The sensor records multiple returns : First Return → typically vegetation canopy tops. ...

Geometric Correction

When satellite or aerial images are captured, they often contain distortions (errors in shape, scale, or position) caused by many factors — like Earth's curvature, satellite motion, terrain height (relief), or the Earth's rotation . These distortions make the image not properly aligned with real-world coordinates (latitude and longitude). 👉 Geometric correction is the process of removing these distortions so that every pixel in the image correctly represents its location on the Earth's surface. After geometric correction, the image becomes geographically referenced and can be used with maps and GIS data. Types 1. Systematic Correction Systematic errors are predictable and can be modeled mathematically. They occur due to the geometry and movement of the satellite sensor or the Earth. Common systematic distortions: Scan skew – due to the motion of the sensor as it scans the Earth. Mirror velocity variation – scanning mirror moves at a va...

Image Transformation

In remote sensing, image transformation is used to create new images by manipulating existing ones, enhancing the information extracted from each pixel. Multi-image manipulation and other transformations allow analysts to highlight specific features, compare time-series data, or reduce data dimensions for better interpretation. 1. Multi-Image Manipulation This technique involves applying mathematical operations to multiple images, typically from different bands, dates, or sensors, to highlight specific features or changes. Common methods include: a. Image Addition Purpose : Highlights areas of similarity or enhances features when the same objects appear in multiple images. How it Works : By adding pixel values from two images, the output image emphasizes areas where brightness is high in both. Example : Enhancing overall brightness or detecting seasonal changes by adding images from different times. b. Image Subtraction Purpose : Identifies differences between images, useful for chan...

Spatial Feature Manipulation and Filtering

1. Spatial Feature Manipulation: Spatial Frequency Spatial frequency describes how quickly brightness changes across an image. It can reveal different levels of detail, based on how often these changes occur: High Spatial Frequency : Areas where brightness changes quickly, like edges, fine textures, or detailed patterns. These parts contain high detail but can also include noise. Low Spatial Frequency : Areas with gradual changes in brightness, like smooth surfaces or broad homogeneous areas. These regions are usually featureless, such as water bodies or large agricultural fields. Zero Spatial Frequency : Represents a completely uniform area with no brightness variation. This area is very smooth and has no texture or detail. By manipulating spatial frequencies, we can enhance or suppress certain features in an image. Spatial filtering is one of the primary methods to perform this manipulation. 2. Spatial Filtering and Spatial Domain Spatial filtering is the process of applying mathe...
