A riqueza de uma nação depende, em grande medida, da sua capacidade de aproveitar corretamente os seus recursos naturais, que incluem a água e o solo. O sudoeste da Nigéria é a cintura do cacau, mas tanto as culturas de rendimento como as alimentares têm vindo a diminuir constantemente nos últimos anos, devido à alteração da cobertura do solo e do padrão de precipitação. Este fenómeno constitui uma ameaça à segurança alimentar e exige esforços para explicar a tendência decrescente e fazer recomendações para a sua melhoria. Este livro examina os factores-chave que determinam a utilização da água de irrigação pelos pequenos agricultores, investiga os benefÃcios derivados da utilização da irrigação, acede a outras utilizações alternativas da água de irrigação para além da agricultura e apresenta uma análise comparativa dos solos de locais selecionados na área de estudo no que diz respeito ao rendimento das culturas. Foi adoptada uma nova técnica que combina inquéritos de campo com análises socioeconómicas. Para uma produção agrÃcola sustentável através de múltiplas culturas ao longo de todo o ano na área de estudo, deve ser atribuÃdo um elevado prémio à irrigação e as utilizações não agrÃcolas da água pelos agregados familiares devem ser incluÃdas no planeamento da irrigação para uma gestão holÃstica e eficaz dos recursos hÃdricos.
