    Perceptions and realities of hydroclimatic change affecting Guyanese rice farming
    Mahdu, Omchand; Ellis, Andrew W. (Elsevier, 2021-07-21)
    This study explores small farmers’ perceptions of changes in climate across Guyana’s riceproducing regions. Qualitative, primary data were collected from a random sample of 189 small farmers, supplemented with 28 key informants, from across Guyana’s five main riceproducing regions. The most prevalent perception related to precipitation among farmers is an increase in rainfall year-round (56%), while for informants, it is an increase in rainfall intensity (81%). When considering the atmospheric conditions of temperature and humidity, farmers (88%) and informants (96%) overwhelmingly perceive warmer conditions. Considering weather and climate volatility, farmers (72%) and informants (82%) most prevalently perceive an increase in excess rainfall/flooding, but secondly, farmers (58%) and informants (71%) communicated a perceived increase in drought. Secondary quantitative hydroclimate data support the perception of a wetter climate, and to some degree, increased hydroclimatic volatility. Precipitation is critical to rice cultivation, and the data sets, combined, signal a wetter Guyanese climate, which has major economic implications for small farmers, the broader rice industry, and the economy of Guyana. However, granularity in farmers’ perceptions suggests a need for more detailed hydroclimate monitoring across Guyana. Thus, strengthening the Guyanese Hydrometeorological Service to support improved spatial and temporal monitoring and collection of primary weather data would be a wise investment in short- and long-term climate mitigation efforts.
