Sicurezza del cibo

Geografia - Anno 9

Chunk 1Chunk 2
Nel 2050 la popolazione mondiale sarà 9 miliardi.
Nel futuro dovremo produrre tra il 60% e il 100% più del cibo.
Per produrre più cibo possiamo aumentare l'intensità delle coltivazioni.
Se utilizziamo zone naturali per l'agricoltura questo riduce la biodiversità.
Se usiamo più fertilizzanti e pesticidi questo può migliorare la resa agricola.
Aumentare l'intensità delle coltivazioni significa coltivare 2 o 3 prodotti diversi in un anno nella stessa area.
Gli alimenti di base si consumano regolarmente e sono una parte fondamentale della dieta.
Il riso, il mais e il grano rappresentano il 60% dell'energia che si consuma nel mondo.
I legumi, la frutta e il pesce sono altri esempi degli alimenti di base.
