KZN Agricultural Conditions Monitoring Report February 2011

This report provides an overview of the agricultural conditions in Kwazulu-Natal in February 2011, focusing on dam levels and rainfall across the province. Most dams maintained their levels, except for Hluhluwe Dam, now above 70% for the first time since 2004, and Nagle Dam, which decreased by 18%. Satellite monitoring and medium-term rainfall predictions are discussed. Despite below-average vegetation conditions in some areas, groundwater from previous rains is expected to sustain plant growth. The SA Weather Bureau forecasts continued below-normal rainfall for March, April, and May.

  1. MONITORING AGRICULTURAL CONDITIONS IN KWAZULU-NATAL February 2011 Provincial Dam levels Rainfall across KZN Green = 70 – 100%; Yellow = 40 – 69.9 %; Red < 40% of full storage capacity. Most dams remained the same or showed a slight decrease in level due to the low February rainfall. The exceptions are the Hluhluwe Dam, which is now above 70% for the first time since 2004, and Nagle Dam, which dropped by 18 %, fyui. Using satellites to monitor conditions Medium term rainfall prediction In previous reports, Normalized Differential Vegetation Index (NDVI) data were being provided through the UN FEWS website every 10 days. However, due to satellite technical problems these data are no longer being provided. Hot, dry weather during February has lead to below average vegetation conditions developing around Durban and parts of the KZN Midlands. However, there appears to be sufficient ground water available from the good rains during December and January to sustain plant growth through most of KZN. The SA Weather Bureau is predicting below-normal rainfall for most of KZN for March, April and May, an indication that the below average rainfall will continue. Prepared by: O.
