ABSTRACT Inadequate and intensive management of soils can promote changes in their chemical attributes and impair the quality of surface and groundwater, especially in hillside areas. Therefore, the aim of this study was to identify possible changes in soil and water chemical composition of hillside areas cultivated with horticulture. For this, chemical attributes of three soil depths (0-10, 10-30, and 30-60 cm) were determined in three hillside positions (upper, middle, and lower thirds) of five hillside and adjacent forest areas, as well as water from reservoirs for agricultural use and human consumption. Compared with the forest area, horticultural areas present soil with lower organic matter content and CEC, but higher values of pH, base saturation,... |

A limitação de recursos hídricos dificulta a produção de alimentos em regiões semiáridas, com distribuição irregular de precipitações pluviométricas. Dessa forma, a otimização desses recursos, captando água de chuva para uso doméstico, para a criação de animais e para a produção de alimentos se torna uma necessidade premente. Outra alternativa é utilizar a água armazenada em pequenas bacias de captação (lagoas, barreiros, pequenos açudes) que se formam durante o período chuvoso para cultivos de hortas e pomares. No caso de hortaliças, com espaçamentos pequenos entre plantas, deve-se molhar uma faixa contínua do solo, enquanto em fruteiras, com plantas de maior porte, recomenda-se molhar manchas de solo, aplicando-se uma quantidade menor de água por área,... |

The purpose of this report is to show the process of the intervention made through the implementation of the IWRM and Food Security Demonstration Project in Zambia. The report gives details of the project processes, showing the steps the project went through, the outcomes and its impact on the communities where it was implemented. The report is the result of a number of field visits made to the completed project sites, the sources of information have been; focus group meetings, interviews, discussions with key informants, beneficiaries the youth, male and female stakeholders and reviews of project activity reports, and direct observations. Therefore, what is presented here is a cumulative “factual and real time” opinion as to what has been observed and... |
