The scarcity of water resources throughout the semiarid
region of Brazil's Northeast make it nearly impossible to either produce
surplus crops or to keep a livestock of cattle, goats and sheep, usually the
main source of income as well as savings of small farmers. To live in this region
requires that farmers, particularly those living in dry areas, use some
alternative technologies, mainly the catchment and storing of rainwater.
Researching the application of these alternative technologies, we discovered
that few farmers use any rainwater catchment technology.
The objective of this study was to evaluate the rainwater
catchment and storage technologies of small farmers in five counties in the
semiarid region. Our research was carried out between 1996 and 1998 in the
counties of Simplicio Mendes (Piaui), Morada Nova (Ceara), Angicos (Rio Grande
do Norte), Jeremoabo (Bahia) and Inaja (Pernambuco). In each county a random
sample group of farmers was asked to answer a questionnaire.
A total of 179 farmers were asked if they use: 1)cisterns,
2) clay pits for supplement irrigation, 3) underground storage dams, 4) their
own rainwater catchment systems and 5) reasons for not using any technologies.
The results obtained show that only 9,5% of the farmers use
cisterns. And that 51,96% of the farmers not using them would have enough money
to install them. No other technologies were used by any of the farmers. These
results show the necessity for spreading the knowledge of these technologies
among small farmers.
