Guardian: By 2050, well have to meet the gargantuan challenge of growing 50% more food, to feed a burgeoning global population. Enter climate-resilient agriculture, possibly the best chance we have of actually attaining this goal: as countries grapple with the effects of climate change--drought, higher salinity--increasingly well have to depend on crops that can also flourish despite its inconsistencies. Research on agricultural resilience abounds, but the latest offering looks to plant genetics for a solution,...
