The underground dam is an impressive rainwater storage
technology in the Brazilian semiarid region, that was
disseminated in rural communities through the P1 + 2
Program. In this region, rainfall irregularities compromise
agricultural sustainability, a scenario which is aggravated
by climate change. Research under these conditions can
result in sustainable management recommendations for
di!erent water availability. In addition, usingagroecological
practices integrated with rainwater capture and storage
technologies contributes to increasing the resilience of
systems in the face of climate change (Figure 1). This Project
aimed to reduce the risks of family farming systems in the
Semi-Arid region through usingintegrated water technology
in three conditions of rainfall. For this, nine underground
dams were selected in producing areas, under three
conditions of rainfall in the 250 to 350 mm ranges; 351
to 500 mm and 501 to 750 mm, in the states of Paraíba,
Pernambuco and Bahia, respectively. The following actions
were taken: implementation of soil tillage systems involving
organic matter, charcoal and microorganisms, e"ciency in
using water; monitoring of water and soil characteristics;
assessment of the potential of energy species; economic
evaluation; use of supplementary irrigation. The source of
the funds: Embrapa.
