Different innovations in Plant science are important for helping farmers in conserving biodiversity and providing a sustainable food supply for all

According to United Nations Food and Agriculture Organization (FAO), food production still needs to increase by 70% if we are willing to feed nine billion people by 2050. To achieve this, a further 30 million hectares cropland may be needed (OECD). If biodiversity is to be preserved, the amount of parkland, forests and natural habitats brought into agricultural use has to be minimised.

Togetherly, plant science technology, crop protection and plant biotechnology, will help farmers in increasing the productivity of existing arable land in use, resulting in reduction of the need of expanding agricultural land, limiting the loss of biodiversity and natural habitats. Whereas, biotech crops are already contributing to higher yields for many farmers around the world who have potential to increase yields globally by up to 25%. Plant breeding practices, including biotechnology, have further led to an increase in the genetic variety of crops.

Crop protection and plant biotechnology products will increase agricultural productivity by reducing crop losses to pests and disease. Without them, yield losses would double to reach 40-80%. They are critical to protecting local biodiversity from the impact of invasive alien species, such as the salt cedar tree in the US, which can consume up to 1,000 liters of water in one day, and increase the salinity of surrounding water and soil. Agriculture is both reliant on a rich ecosystem, and a vital force in maintaining it.

Farmers today are facing a double challenge of having to increase their productivity while preserving the rich biodiversity upon which long-term food security depends.
