The use of drought tolerant crops can increase yield in water-scarce locations, making farming possible in new areas. The adoption of drought tolerant maize in Ghana was shown to increase yield by more than 150% and boost commercialization intensity, although it did not significantly affect farm income.
In India, GM cotton yields in Maharashtra, Karnataka, and Tamil Nadu resulted in an average 42% increase in yield in 2002, the first year of commercial planting. A severe drought in Andhra Pradesh that year prevented any increase in yield, because the GM strain was not drought tolerant. [525] Drought-tolerant variants were later developed.
Bill Gates has been among the proponents of a second green revolution, saying: [5]. Three quarters of the world's poorest people get their food and income by farming small plots of land...if we can make smallholder farming more productive and more profitable, we can have a massive impact on hunger and nutrition and poverty...the charge is clear—we have to develop crops that can grow in a ...
Genetically modified organisms refers to any plant, animal or microorganism that has been genetically altered, due to modern biotechnology like genetic engineering. Often, GMOs are labeled “GE ...
Increasing the diversity of crops by introducing new genetic resources can increase yields by 10 to 15 percent compared to when they are grown in monoculture. [ 128 ] [ 129 ] Perennial crops reduce the need for tillage and thus help mitigate soil erosion, and may sometimes tolerate drought better, increase water quality and help increase soil ...
The genetically modified organisms, including potato, tomato, and spinach are applied in the production of substances that stimulate the immune system to respond to specific pathogens. [15] With the help of recombinant DNA techniques, the genes encoded for viral or bacterial antigens could be genetically transcribed and translated into plant cells.
In 2014, 181.5 million hectares of genetically modified crops were planted in 28 countries. Half of all GM crops planted were genetically modified soybeans, either for herbicide tolerance or insect resistance. Eleven countries grew modified soybean, with the USA, Brazil and Argentina accounting for 90% of the total hectarage.
Genetically modified rice are rice strains that have been genetically modified (also called genetic engineering). Rice plants have been modified to increase micronutrients such as vitamin A , accelerate photosynthesis , tolerate herbicides, resist pests, increase grain size, generate nutrients, flavors or produce human proteins.
