Figure 11From: Analyzing the spatio-temporal relationship between dengue vector larval density and land-use using factor analysis and spatial ring mapping Relationship between low and high Breteau index (B.I.) having different land-cover and land-use. Twelve representative factors were extracted on the basis of factor analysis. Equal/approximately equal percentage of area showed that there was no difference between land-cover/land-use having a B.I. of less than 20 and a B.I. of greater than 50. Difference in land-cover and land-use area (percentage) represents significance difference in B.I.Back to article page
