Chipko movement.

The act of observing and assessing the current state and ongoing changes in ecosystem, biodiversity components, landscape including natural habitats, populations and species. An agricultural drone is an unmanned aerial vehicle applied to farming in order to help increased crop production and monitor crop growth. Agricultural drones let farmers see their fields from the sky. This bird’s eye-view can reveal many issues such as irrigation problems, soil variation and pest and fungal infestations. It is also used for cost effective safe method of spraying pesticides and fertilizers, which proves very easy and non-harmful.

Lakes as storage of rainwater provide drinking water, improves groundwater level and preserve the fresh water bio-diversity and habitat of the area wherein occurs.
In terms of services, lakes offer sustainable solutions to key issues of water management and climatic influences and benefits like nutrient retention, influencing local rainfall, removal of pollutants, phosphorous and nitrogen and carbon sequestration.

Biochar is a long term method to store carbon. To increase plants ability to store more. carbon, plants are partly burnt such as crop waste, waste woods to become carbon-rich slow decomposing substances of material called Biochar. It is a kind of charcoal used as a soil amendment. Biochar is a stable solid, rich in carbon and can endure in soil for thousands of years. Like most charcoal, biochar is made from biomass via pyrolysis. (Heating biomass in a low oxygen environment) which arrests wood from complete burning. Biochar thus has the potential to help mitigate climate change via carbon sequestration. Independently, biochar, when added to the soil, can increase soil fertility of acidic soils, increase agricultural productivity, and provide protection against some foliar and soil-borne diseases. It is a good method of preventing waste woods and logs getting decayed instead we can convert them into biochar thus converting them to carbon storage material.

In-situ conservation means conservation and management of genetic resources in their natural habitats. Here the plant or animal species are protected within the existing habitat. Forest trees, medicinal and aromatic plants under threat are conserved by this method. This is carried out by the community or by the State conservation which includes wildlife, National park, and Biosphere reserve. The ecologically unique and biodiversity-rich regions are legally protected as wildlife sanctuaries, National parks and Biosphere reserves. Megamalai, Sathyamangalam wildlife, Guindy and Periyar National park, and Western Ghats, Nilgiris, Agasthyamalai, and Gulf of Mannar are the biosphere reserves of Tamil Nadu.

Chipko Movement:
The tribal women of Himalayas protested 'against the exploitation of forests in 1972. Later on, it transformed into Chipko Movement by Sundarlal Bahuguna in Mandal village of Chamoli district in 1974. People protested by hugging trees together which were felled by a sports goods company. Main features of Chipko movement were,
(i) This movement remained nonpolitical
(ii) It was a voluntary movement based on Gandhian thought.
(iii) It was concerned with the ecological balance of nature
(iv) Main aim of Chipko movement was to give a slogan of five F's - Food, Fodder, Fuel, Fibre and Fertilizer, to make the communities self-sufficient in all their basic needs.

Prosopis juliflora is used to arrest wind erosion and stabilize sand dunes on coastal and desert areas. It can absorb hazardous chemicals from soil and it is the main source of charcoal.

(i) Training on tree growing methods
(ii) Publicity and propaganda regarding tree growing
(iii) Formation of demonstration plots
(iv) Raising and supply of seedlings on subsidy
(v) Awareness creation among school children and youth about the importance of forests through training and camps.

Clean Development Mechanism (CDM) is defined in the Kyoto protocol (2007) which provides project-based mechanisms with two objectives to prevent dangerous climate change and to reduce greenhouse gas emissions. CDM projects help countries to reduce or limit emissions and stimulate sustainable development.
An example of CDM project activity is the replacement of conventional electrification projects with solar panels or other energy efficient boilers. Such projects can earn Certified Emission Reduction (CER) with credits/scores, each equivalent to one tonne of CO₂, which can be counted towards meeting Kyoto targets

Ozone depletion in the stratosphere results in more UV radiations especially UV B radiations (shortwaves). UV B radiation destroys biomolecules (skin ageing) and damages living tissues. UV - C is the most damaging type of UV radiation, but it is completely filtered by the atmosphere (ozone layer). UV-a contributes 95% of UV radiation which causes tanning burning of skin and enhancing skin cancer. Hence the uniform ozone layer is critical for the wellbeing of life on earth.

(i) Increasing the vegetation cover, grow more trees
(ii) Reducing the use of fossil fuels and greenhouse gases
(iii) Developing alternate renewable sources of energy
(iv) Minimizing uses of nitrogenous fertilizers, and aerosols.

(i) Low agricultural productivity in tropics
(ii) Frequent heat waves (Weeds, pests, fungi need warmer temperature)
(iii) Increase of vectors and epidemics
(iv) Strong storms and intense flood damage
(v) Water crisis and decreased irrigation
(vi) Change in flowering seasons and pollinators
(vii) Change in Species distributional ranges
(viii) Species extinction

(i) Coal based power plants, by the burning of fossil fuels for electricity generation.
(ii) Combustion of fuels in the engines of automobiles, commercial vehicles, and air planes contribute the most of global warming.
(iii) Agricultural practices like stubble burning result in emission of CO₂.

(i) Rise in global temperature which causes sea levels to rise as polar ice caps and glaciers begin to melt causing submergence of many coastal cities in many parts of the world.
(ii) There will be a drastic change in weather patterns bringing more floods or droughts in some areas.
(iii) Biological diversity may get modified, some species ranges get redefined. Tropics and sub-tropics may face the problem of decreased food production.
