Em um editorial recente, abordei o t\u00f3pico dos biocombust\u00edveis se tornando um bode expiat\u00f3rio para v\u00e1rios problemas s\u00e9rios na agricultura moderna, sendo o mais importante o r\u00e1pido aumento dos pre\u00e7os dos alimentos.<\/p>\n

As opini\u00f5es que recebi sobre o assunto foram mistas. Alguns leitores acreditavam (corretamente, eu acho) que parte do problema certamente se deve \u00e0s mudan\u00e7as na \u00e1rea de cultivo e \u00e0 menor disponibilidade de milho para ra\u00e7\u00e3o, que contribu\u00edram para o aumento dos pre\u00e7os \u2014 um leitor na China observou que o custo do leite, em particular, disparou, como resultado do aumento dos custos para os produtores de leite.<\/p>\n

Por outro lado, como mencionei no editorial, h\u00e1 tamb\u00e9m uma certa dose de rea\u00e7\u00e3o reacion\u00e1ria que n\u00e3o \u00e9 t\u00e3o bem fundamentada. O pre\u00e7o do arroz, que tamb\u00e9m aumentou e representa o maior problema para o abastecimento mundial de alimentos, visto que \u00e9 a nossa cultura alimentar mais importante em geral, \u00e9 apenas ligeiramente afetado pela produ\u00e7\u00e3o de biocombust\u00edveis. \u00c9 claro que os custos dos insumos para os produtores de arroz s\u00e3o afetados pelos aumentos de pre\u00e7os, mas n\u00e3o no mesmo n\u00edvel de culturas cultivadas de forma mais intensiva. Nesse caso, o clima \u00e9 o tema mais importante, especialmente \u00e0 medida que adquirimos uma compreens\u00e3o mais clara da quest\u00e3o debatida do aquecimento global.<\/p>\n

Li recentemente um artigo sobre dawn.com<\/a>, um site de not\u00edcias paquistan\u00eas, que discute o aumento repentino no pre\u00e7o (em alguns casos dobrando, ou mais) do arroz no pa\u00eds, o que levou a muitos outros problemas, como revendedores cortando o pr\u00eamio com qualidades baixas e consumidores comprando o m\u00ednimo poss\u00edvel para sobreviver.<\/p>\n

A rea\u00e7\u00e3o imediata de v\u00e1rios governos asi\u00e1ticos foi intervir e tentar deter o aumento dos pre\u00e7os com manobras pol\u00edticas: o artigo observa que a \u00cdndia pediu uma proibi\u00e7\u00e3o de exporta\u00e7\u00e3o para manter os pre\u00e7os sob controle; outros pa\u00edses implementaram ou est\u00e3o considerando sistemas de racionamento ou imposi\u00e7\u00e3o de impostos de exporta\u00e7\u00e3o para manter o arroz no pa\u00eds.<\/p>\n

\u00c9 dif\u00edcil dizer se essas iniciativas s\u00e3o sustent\u00e1veis. Talvez daqui a um ano e com uma safra forte de arroz, os problemas sejam resolvidos e os pre\u00e7os possam voltar ao normal. Mas, caso contr\u00e1rio, ainda h\u00e1 esperan\u00e7a para o arroz, na forma de tecnologias de sementes.<\/p>\n

Muitos grupos e empresas est\u00e3o se concentrando em variedades de arroz tolerantes \u00e0 seca, incluindo grandes empresas de sementes, institui\u00e7\u00f5es acad\u00eamicas e \u00f3rg\u00e3os governamentais. E, felizmente, tamb\u00e9m h\u00e1 bastante colabora\u00e7\u00e3o para colocar essas tecnologias em pr\u00e1tica.<\/p>\n

Talvez n\u00e3o haja um problema com mais peso na agricultura hoje e nos pr\u00f3ximos anos. Na verdade, se os biocombust\u00edveis forem responsabilizados pela fome, pode ser simplesmente porque, enquanto os biocombust\u00edveis roubam os holofotes da m\u00eddia e dos departamentos de P&D em todo o mundo, a quest\u00e3o mais urgente que enfrentamos recebe menos aten\u00e7\u00e3o.<\/p>\n

Se as mudan\u00e7as clim\u00e1ticas forem levadas a s\u00e9rio, precisamos estar preparados para mudar nossos m\u00e9todos de produ\u00e7\u00e3o agr\u00edcola; a escassez de \u00e1gua significa mais colheitas com menos gotas. O trabalho que est\u00e1 sendo feito agora com culturas tolerantes \u00e0 seca, mesmo que passe despercebido pelos radares da m\u00eddia que continuam focados em biocombust\u00edveis, pode ser o que nos permitir\u00e1 evitar um futuro de aumento da fome no mundo.<\/p>","protected":false},"excerpt":{"rendered":"
