Hey mate here is your ans.
Organic agriculture occupies only 1% of global agricultural land, making it a relatively untapped resource for one of the greatest challenges facing humanity: producing enough food for a population that could reach 10 billion by 2050, without the extensive deforestation and harm to the wider environment.
The study, Organic Agriculture in the 21st Century, published in Nature Plants, is the first to compare organic and conventional agriculture across the four main metrics of sustainability identified by the US National Academy of Sciences: be productive, economically profitable, environmentally sound and socially just. Like a chair, for a farm to be sustainable, it needs to be stable, with all four legs being managed so they are in balance.
It is found that although organic farming systems produce yields that average 10-20% less than conventional agriculture, they are more profitable and environmentally friendly. Historically, conventional agriculture has focused on increasing yields at the expense of the other three sustainability metrics.
The flower petals and the labels represent different sustainability metrics that compare organic farming with conventional farming. They illustrate that organic systems can better balance the four areas of sustainability: production (orange), environment (blue), economics (red) and social wellbeing (green).
In addition, organic farming delivers equally or more nutritious foods that contain less or no pesticide residues, and provide greater social benefits than their conventional
With organic agriculture, environmental costs tend to be lower and the benefits greater. Biodiversity loss, environmental degradation and severe impacts on ecosystem services – which refer to nature’s support of wildlife habitat, crop pollination, soil health and other benefits – have not only accompanied conventional farming systems, but have often extended well beyond the boundaries of their fields, such as fertilizer runoff into rivers.
Overall, organic farms tend to have better soil quality and reduce soil erosion compared to their conventional counterparts. Organic agriculture generally creates less soil and water pollution and lower greenhouse gas emissions, and is more energy efficient. Organic agriculture is also associated with greater biodiversity of plants, animals, insects and microbes as well as genetic diversity.
