Low-costweather station network
The high variability in rainfall and dry seasons increases uncertainty about the appropriate dates for planting, applying agricultural inputs, identifying potential emergence of pests and diseases, and other post-harvest activities.
Climate challenge
Practice description
Each weather station is comprised of a rain gauge and a Six's thermometer. The location of the stations are determined by an agroclimatic analysis in the climate-smart village’s area. In addition, soil moisture is measured by a tensiometer to determine the soil water requirement. The station is monitored every day, and the community discuss about the behavior of the different variables. This information is expected to provide feedback to Cauca’s Local Agroclimatic Committee.
Technical aspects
The practice emphasizes adaptation as it seeks to improve farmers' decision-making processes by monitoring climate variables. Also offers co-benefits in mitigation by achieving a better application of agricultural inputs.
Implementation and results
Contribution to CSA pillars
How can farmers' decision-making processes be improved by monitoring climate variables?
Research question
The stations consist of a plasticrain gauge of 120 mm and aSix's thermometer with itsown weather coat.
A tensiometer has also been includedto measure the soil moisture at 30 cm depthand its pH.
The main network comprises Four stationswith altitudinal difference between themof 100 masl, in a range of 5 km. The supportnetwork comprises 16 additional stations.
