Desertification Effects on Agriculture 
Impact on
Soil Quality One of the primary effects of desertification on agriculture is the degradation of soil quality
...Quality Before and After Desertification Parameter Before Desertification After Desertification
Organic Matter Content High Low Water Retention Capacity High Low Nutrient Levels Adequate Depleted Loss
...
Millipedes They are detritivores, which means they feed on decaying plant
matter and
organic material
...diet is important for the ecosystem, as millipedes help break down dead plant material and recycle nutrients back into the
soil ...
Ecosystem Functions in Tundras These plants play a vital role in capturing solar energy through photosynthesis, converting it into
organic matter that forms the base of the food chain
...For example, many tundra plants have shallow root systems to access nutrients in the thin layer of
soil above the permafrost
...
How Insects Contribute to Ecosystem Services Decomposition Insects are vital in the decomposition of
organic matter ...They break down dead plants and animals into simpler forms, releasing nutrients back into the
soil ...
Wetlands and Their Impact on Soils They are areas where water covers the
soil, either permanently or seasonally, and are home to a diverse range of plant and animal species
...Nutrient Cycling: Wetlands play a vital role in nutrient cycling, with
organic matter decomposing in the waterlogged conditions and releasing nutrients back into the soil
...
Reducing Environmental Impact with Sustainable Methods Sustainable Agriculture Sustainable agriculture focuses on practices that promote
soil health, conserve water, and reduce the use of synthetic chemicals
...By employing techniques such as crop rotation,
organic farming, and integrated pest management, farmers can increase crop yields while minimizing environmental harm
...Composting Composting is a natural process that recycles organic
matter into nutrient-rich soil conditioner
...
Pollution Reduction Strategies Types of Pollution Pollution can take many forms, including air pollution, water pollution,
soil contamination, and noise pollution
...combat different types of pollution: Air Pollution Air pollution is caused by the release of harmful gases and particulate
matter into the atmosphere
...through soil testing and cleanup efforts Implementing proper waste disposal practices to prevent soil contamination Using
organic farming methods to reduce reliance on chemical fertilizers and pesticides Implementing soil erosion control measures to prevent the loss of topsoil International Agreements
...
Insect Conservation Needs Some key strategies include: Creating and protecting natural habitats for insects Reducing pesticide use and promoting
organic farming Restoring native plant species to support insect populations Educating the public about the importance of insects in the ecosystem Importance of Insect Conservation
...essential for: Pollination of plants, including many crops Breaking down organic
matter and recycling nutrients in the
soil Serving as a food source for birds, reptiles, and other animals Table: Endangered Insect Species Species Threats Conservation Status Butterfly
...
Biotic Decomposition: Insects like beetles, ants, and flies are essential in breaking down
organic matter, such as dead plants and animals
...They help in recycling nutrients back into the
soil ...
Insects and Their Role in Ecosystem Engineering insects contribute to ecosystem engineering: Building and modifying nests Creating burrows and tunnels Breaking down
organic matter Modifying plant structures Aiding in pollination Examples of Insects as Ecosystem Engineers Let's explore some examples of insects that are known for their
...Ecosystem Engineering Role Ants Ants are known for their extensive tunneling activities, which help aerate the
soil and facilitate nutrient cycling
