Participatory Climate Monitoring (PCM)

Participatory Climate Monitoring (PCM) refers to a set of activities carried out by farmers, with initial support of experts, to monitor climate. Climate Monitoring involves recording data pertaining to all weather parameters of a particular place viz., rainfall, Humidity, temperature, evaporation, wind velocity, wind direction and sunshine radiation.  Participatory climate monitoring is a tool that is intended to trigger community action for sustainable use of their land and water resources. The objective is build capacity of the community to collect climate data, discuss the dynamics of local weather and how it is impacting their current agricultural practices.

Apart from the farming community of the particular Hydrological Unit; community leaders/volunteers, sociologists, agriculture extension workers and Hydrogeologist play a facilitating role.

The long-term objective of PCM is to create a platform for farmers to discuss the climate variability factors, their impact on land and water resources, and evolve ‘Community Climate Adaptation Plan (CCAP)’, at the HU level.

The short-term objectives are: 


Climate Monitoring is usually done by Government Departments, such as Meteorology, Ground Water (state and central) and Agriculture Research Stations. Data is collected on a regional scale and gives a general picture of a large area, mandal level.  Presently, the results of climate Monitoring are mainly utilized by the scientific community to identify trends of climate change over a time period.  

A farmer who is away from communication network is usually not in a position to either understand its importance or use the data to his/her advantage. Hence it is strongly believed that farmers / local communities should participate in data collection and analysis, and identify impacts on local livelihoods. Participatory climate Monitoring aims at empowering farmers with simple tools for recording weather parameters and interpret them for their benefit.

Instruments which farmers will use to measure climate parameters are: 




(Dry and wet)

For Measurement of Humidity

Temp determines rate of plant growth, length of vegetative period and biomass production. High temp reduces the ripening period of grain crops.

Helps determine crop irrigation

Forecasting of crop diseases – increase pest infestation during high humidity with cloudy weather.

2. Thermometers 
(Max and Min)

For Measurement of Temperature

3. Raingauge

For Measurement of Rainfall

Planning for crop water requirement

Irrigation scheduling

4. Open pan Evaporimeter

For Measurement of Evaporation

5. Anemometer

For Measuring wind velocity

Wind velocity and direction determine pollens fertilization of plants. Strong wind decreases the photosynthesis process in plants and damages the plant.

Critical stage of plant growth is dependent on solar radiation. Also determines the fertilizer use efficiency of plants.

6.Wind wane

For Measuring wind direction

7. Sunshine recorder

For Measuring  sunshine radiation


The steps in establishing a Participatory Climate Monitoring (PCM) system include:

Climate Change Adaptation Committees (CCACs) will play a key role in feasibility study, site selection, establishment of climate monitoring stations, selection of volunteers, data collection and dissemination, safeguard and maintenance of equipment, and serve as a platform to discuss the climate variability factors, their impact on land and water resources, and identify adaptation options.
