At Commodity Classic in New Orleans earlier this month, I spoke with growers about whether conventional ag is the way to feed a growing population.<\/p>\n<p>My answer: there is no silver bullet when it comes to sustainable agriculture. There is no single system, no one-size-fits-all prescription that can solve our food security and environmental sustainability challenges.<\/p>\n<p>That\u2019s why we cannot afford to shut the door on any idea, or on any system of food production. Here\u2019s how organic and conventional compare on yields and environmental impacts, and why we need both systems, local and global production, and big and small farms in order to protect food security and the planet.<!--more--><\/p>\n<p><strong>Yield and intensification<\/strong><\/p>\n<p>To feed 9 billion people by 2050, we will undoubtedly need higher yields and in some places, intensified production.\u00a0 Which system comes out ahead?

Some areas \u2013 in particular sub-Saharan Africa \u2013 lack access to adequate conventional crop inputs, or farmers face economic risk in purchasing those inputs \u2013 but yield gaps can diminish by utilizing organic sources of nutrients or non-chemical pest and weed control methods, which may be more readily accessible.<\/li>\n<li>There are also places where conventional comes out the yield winner and allows farmers to intensify productivity on existing lands, thereby avoiding cultivation of more marginal and environmentally sensitive lands.<\/li>\n<\/ul>\n<p><strong>Environmental outcomes <\/strong><\/p>\n<figure id=\"attachment_6019\" aria-describedby=\"caption-attachment-6019\" style=\"width: 300px\" class=\"wp-caption alignright\"><a href=\"https:\/\/blogs.edf.org\/growingreturns\/wp-content\/blogs.dir\/52\/files\/2016\/03\/24443679794_b3c15e77bd_b.jpg\" rel=\"attachment wp-att-6019\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6019 size-medium\" src=\"https:\/\/blogs.edf.org\/growingreturns\/wp-content\/blogs.dir\/52\/files\/2016\/03\/24443679794_b3c15e77bd_b-300x199.jpg\" alt=\"24443679794_b3c15e77bd_b\" width=\"300\" height=\"199\" srcset=\"https:\/\/blogs.edf.org\/growingreturns\/wp-content\/blogs.dir\/52\/files\/2016\/03\/24443679794_b3c15e77bd_b-300x199.jpg 300w, https:\/\/blogs.edf.org\/growingreturns\/wp-content\/blogs.dir\/52\/files\/2016\/03\/24443679794_b3c15e77bd_b-768x509.jpg 768w, https:\/\/blogs.edf.org\/growingreturns\/wp-content\/blogs.dir\/52\/files\/2016\/03\/24443679794_b3c15e77bd_b.jpg 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-6019\" class=\"wp-caption-text\">Credit: Flickr user <a href=\"https:\/\/www.flickr.com\/photos\/137169575@N04\/24443679794\" target=\"_blank\" rel=\"noopener noreferrer\">Aqua Mechanical<\/a><\/figcaption><\/figure>\n<p>The debate over the environmental outcomes of organic compared to conventional agriculture has also been extensive, and often contradictory. As is often true, it likely comes down to your metric. Several <a href=\"http:\/\/csanr.wsu.edu\/organic-farming-environmental-benefit-yield-cost\/\" target=\"_blank\" rel=\"noopener noreferrer\">meta-analyses<\/a> in the past decade have shown lower environmental impacts from organic on a per unit area basis, but a better outcome environmentally for conventional on a per unit product basis.<\/p>\n<p><a href=\"http:\/\/www.nationalgeographic.com\/foodfeatures\/feeding-9-billion\/\" target=\"_blank\" rel=\"noopener noreferrer\">And it all depends how things are done<\/a>. For example, all farmers have to deal with weeds and bugs. Conventional farmers can use synthetic herbicides and pesticides to keep these at bay to protect their crops. If they manage these inputs poorly, they can contribute to climate and water pollution and health concerns. If used efficiently,\u00a0those same herbicides and pesticides can make it easier for farmer to adopt no-till and other practices that bring a net benefit to the environment when soil gets healthier, erosion slows, and water and air quality improves.<\/p>\n<p>Organic farmers cannot use synthetic inputs, so may turn to frequent mechanical weeding, which can be done really well, or lead to negative impacts on nesting birds, worms and invertebrates and even higher use of fossil fuels, thereby increasing pollution from nitrogen oxides.<\/p>\n<p>In organic systems, getting crop nutrients from manure is beneficial to soils. But poorly managed manure can lead to water quality, odor, and health problems. And the challenges of managing manure \u2013 weight, inconsistencies in nutrient and solids content, and limited options for application \u2013 can make it harder than using synthetic fertilizer. When applied precisely, synthetic fertilizer can reduce nutrient loss and impacts to water and air.<\/p>\n<p><strong>All production systems can improve<\/strong><\/p>\n<div class=\"simplePullQuote right\"><p>\u201cI don&#8217;t think that either organic or conventional is \u2018better.\u2019 They are different approaches to growing\u00a0food, each with their pros and cons, and each representing a different\u00a0trade-off.
