The new green revolution use of biotechnology
Irrigation
Where water supply is insufficient
Huge pivotal sprinklers, which tend to be wastefully used as a method include trip irrigation, water pipes on the ground that deliver water direct to the roots of individual plants
Irrigation commonly involves a local obstruction of water from underground, aquifers, or nearby. Rivers can involve lengthy water transfer.
Aeropponics and hydroponics
Modern scientific techniques to grow plants without soil
Plants can be grown throughout the year and artificially lit and heated green houses. The plants grow quickly as nutrients reply directly to the roots and disease is found in sales are eliminated. However, they are expensive in require a great deal of expert knowledge.
Biotechnology
Biotechnology is a controversial, scientific approach and increasing yield by modifying products or processes. Genetically modified crops can increase crop production by using fewer chemicals and are missing less CO2.
Appropriate technology
Low tech solution that makes use of local people and cheap or recycled materials commonly used. An LIC is often promoted by non-government organisations and charities. It may involve simple water, harvesting techniques, irrigation, schemes, or processing, such as using bicycle power to D husk coffee beans.
The new green revolution use of biotechnology
Original green revolution was highly successful and introducing modern from practices in part of the developing world in the 1950s, and the 1960s
The new green revolution involves I’m all sustainable and environmentally friendly approach, for example, promoting nutrient cycling through cup rotation and livestock farming in less fertile areas
Sustainable food supply strategies
Organic farming
Permaculture
Urban farming initiatives
Fish and meat from sustainable sources
Seasonal food consumption
Reduced waste and losses
Organic farming
Organic farming involves to production of food, without the use of chemicals, such as pesticides, insecticide, and artificial fertilisers widespread across the world
Organic food production is in harmony with nature and reduces the harmful effects of chemicals. However, it tends to be more labour-intensive use smaller, which means it can be more expensive to the consumer.
Permaculture
Is similar to organic farming that promotes farming is in harmony with the natural environment advocates for using natural systems. Frozen artificial chemicals, for example, using ladybirds as natural predators for aphid control.
Permaculture sustainable, e.g. rainwater harvesting
More popular in Hache ICs
Urban farming initiatives
Community initiatives involving the conversion of waste of derelict land into productive, farmland or vegetable gardens include roof garden, patio Gardens
Increases feet, purity and healthier diets and improve natural environments
Fish and meat from sustainable sources
Now says on food labels, giving customers the power to make more sustainable choices
Sustainable fishing, conserves, fish, stocks and avoids harmful overfishing. European Union apply strict fishing controls.
Sustainable livestock past affect low intensity, systems, free range animal welfare
Seasonal food consumption
Local farmers to buy seasonal produce to reduce air miles and greenhouse gases reduce its carbon footprint and provides jobs
Reduced waste and losses
Almost a third of all food produced is wasted HICs over 60% of food, was comprised of fruit and vegetables
Reducing food waste it have a huge positive impact on global food shortages
Including refrigerated, storage, transport, infrastructure processing links to lengthen it, shelf, life, and applying common sense to consuming food beyond its best before date
This is difficult Elysees, as they may not have adequate and chilled storage
