Beyond the patch and across the landscape
Here’s a lofty goal – the 2012 United Nations Rio+20 Conference on Sustainable Development endorsed a target to restore, by 2020, 150 million ha of disturbed and degraded land globally (see ‘That’s a big patch). Although such initiatives can be transformative because of their scope and backing, they require technology and knowledge to deliver proven, scalable restoration. Can it be achieved? We recently examined some of the practicalities of attaining such a target (Menz et al. 2013).
