Question

NGOs are involved in environmental protection aiming to promote ecofriendly technology, stopping degradation and reducing pollution.

With reference to this, write any two ways by which NGO’s help to protect the environment.

State any three ways by which NGOs can use satellite imagery to monitor the global environment.

Answer 1

NGOs help to protect the environment in the following ways:

1. NGOs, through capacity building, develop community capacities such as the ability to mobilise resources, plan, evaluate community initiatives, and solve problems.
2. NGOs have shown leadership in promoting sustainable community development.

NGOs can use satellite imagery to study the global environment in the following ways:

1. Satellites are ideal for monitoring climate change because they can monitor the concentration of greenhouse gases in the atmosphere, such as aerosols, water vapour, carbon monoxide, carbon dioxide, and methane.
2. Satellite Thematic Mapper data are helpful for identifying and classifying wastelands as sand, gullied land, salt-affected areas, and barren rocky areas.
3. Remote sensing observations have been used to monitor drought and flood-related variables from a climatological viewpoint and to assess and quantify drought impacts from an ecosystem perspective.
