app-cotton-explorer

This application explores how climate change might affect the production of cotton in cotton-producing regions around the world. Cotton is the most widely used natural fibre on the planet, with over 22 million tons of raw material produced annually. As an arable crop, cotton grows in specific environments with temperature requirements and sufficient water supply needs to achieve high-quality production.

Based on the agroclimatic indicators from 1951 to 2099 derived from climate projections dataset, this application focuses on the water and temperature requirements that cotton needs to grow to maturity. High quality cotton production requires a very specific environment and this application explores changes in these growing conditions based on the ERA-interim reanalysis and bias-corrected climate datasets. Cotton supply chain stakeholders can use these indicators to compare past and future time periods to improved their understanding of the potential effects of climate changes.

The application interface allows users to select a country and explore agroclimatic indicators relating to cotton for cotton-growing regions within that country. Available countries are: India, China, USA, Brazil, Pakistan, Australia, Turkey, Uzbekistan, Mexico, Argentina, Benin and Greece.

User-selectable parameters

  • Country of interest: the country for which to explore cotton-growing regions.
  • Climate model origin: the origin of the climate model from which agroclimatic indicators are derived.
  • RCP scenario: the climate change scenario for future climate projections.
  • Analysis: the variable to analyse which relates to the production and cultivation of cotton.
INPUT VARIABLES
Name Units Description Source
Growing season length day Number of days between the first occurrence after 1st January (1st July in southern hemisphere) of at least 6 consecutive days with TG > 5°C and the first occurrence after 1st July (1st January in southern hemisphere) of at least 6 consecutive days with TG < 5°C, where TG is the daily mean temperature. This indicator provides an indication whether or not a crop, or a combination of crops, can be sown and subsequently reach maturity within a certain time frame. Agroclimatic indicators
Heavy precipitation days day Number of days per 10 days when RR > 10mm, where RR is the daily precipitation sum. This indicator provides information on crop damage and runoff losses. Agroclimatic indicators
Maximum number of consecutive dry days day Longest period of consecutive days when RR < 1mm, where RR is the daily precipitation sum. This indicator is used for drought monitoring. Agroclimatic indicators
Maximum number of consecutive frost days day Longest period of consecutive days when TN < 0°C, where TN is the daily minimum temperature. This indicator is used as a general frost damage indicator. Agroclimatic indicators
Maximum number of consecutive wet days day Longest period of consecutive days when RR > 1mm, where RR is the daily precipitation sum. This indicator provides information on drought, oxygen stress and crop growth (i.e. less radiation interception during rainy days). Agroclimatic indicators
Maximum of daily maximum temperature K Maximum value of TX over 10 days, where TX is the daily maximum temperature. This indicator provides information on long-term climate variability and change. Agroclimatic indicators
Mean of daily mean temperature K Mean value of TG over 10 days, where TG is the daily mean temperature. This indicator provides information on long-term climate variability and change. Agroclimatic indicators
Minimum of daily minimum temperature K Minimum value of TN over 10 days, where TN is the daily minimum temperature. This indicator provides information on long-term climate variability and change. Agroclimatic indicators
Very heavy precipitation days day Number of days per 10 days when RR > 20mm, where RR is the daily precipitation sum. This indicator provides information on crop damage and runoff losses. Agroclimatic indicators
Wet days day Number of days per 10 days when RR > 1mm, where RR is the daily precipitation sum. This indicator provides information on intercepted reduction. Agroclimatic indicators
OUTPUT VARIABLES
Name Units Description
Number of consecutive cotton growing days day The maximum number of consecutive days in one year which are viable for growing cotton.
