Due to the large size of the ejido (55,295 ha) it was decided to focus the study on the 

 community of X-Hazil Sur (19°23'30"N, 88°05'00"W), the largest of the three villages. In 1992 the 

 population of X-Hazil Sur was 1,040 (Dr. Norbierto Ramirez Morales, in litt.; 539 men and 501 

 women; Figure 2-2). About 52% of the men and 47% of the women were between the ages of 15 and 

 59, while only about 5% of the total population was > 60 years old. During 1989-1992 the population 

 of X-Hazil Sur grew from 950 to 1,040, but this reflected emigration and inmiigration, as well as births 

 and deaths. 



Temperature and precipitation were measured at X-Hazil Sur during July 1989-December 1990 

 (Figure 2-3; Appendix C). The highest temperature recorded was 39°C on 28 and 29 May
