Resumo(s)
Mangrove swamp rice production (MSRP) refers to rice cultivation in former mangrove
soils that have been anthropogenically modified for food production. The method utilizes the largest
possible storage of fresh water to desalinate the soils and make them productive. However, temporal
variability in rainfall patterns causes loss of efficiency in production, impacting crop growth and
reducing productivity. To improve MSRP, it is necessary to identify the primary constraints associated
with salinity, enhancing and maximizing freshwater storage efficiency and water productivity. This
study provides a general description of the MSRP system in both the northern and southern regions
of Guinea-Bissau, aiming at the identification of the main water management limitations. The descrip-
tion involves the use of typologies and the identification of zones with specific characteristics within
the paddies. Furthermore, this review includes an analysis of the physicochemical characteristics
of soils in relation to salinity issues, descriptions of agronomic management, rice varieties, and the
significance of managing dikes and bunds to improve mangrove swamp rice water management. This
study shows how the MSRPS is characterized by dynamism and complexity, involving a wide range
of constraints associated with salinity features, cultural influences, and microclimatic conditions that
are subject to temporal variations.
