Positive and Negative Impacts of Agricultural Production of Liquid Biofuels. Agricultural production of liquid biofuels can have positive effects. It can decrease dependence on fossil fuels and increase farmers' incomes. Agricultural production of mixed perennial biofuel crops may increase pollinator and avian richness
Indian agriculture is plagued by several problems; some of them are natural and some others are manmade.
- Small and fragmented land-holdings:
- Seeds:
- Manures, Fertilizers and Biocides:
- Irrigation:
- Lack of mechanisation:
- Soil erosion:
- Agricultural Marketing:
- Inadequate storage facilities:
Modern agriculture increases global political stability by making more food available, improving its quality and making it accessible to more people. o Development of a robust, rules-based trading system has been extremely important in improving food distribution and increasing accessibility in food-deficit areas.
Aagriculture impacts on our lives in many ways. For instance, we use agriculture to raise animals and grow food, such as tomatoes, carrots, meat and eggs. Agriculture impacts on the foreign exchange of a country. It cuts the import bill, thus reduces the amount imported and saving foreign exchange.
Advantages of Technology in Agriculture:
Modern machines can control the efforts of farmers. They reduce the time. Used supply water to the crops. While Machines are useful in sowing the seeds.Agriculture and AKST can affect a range of health issues including undernutrition, chronic diseases, infectious diseases, food safety, and environmental and occupational health. Poor diet throughout the life course is a major risk factor for chronic diseases, which are the leading cause of global deaths.
Types of Agriculture
- Agriculture not only gives riches to a nation, but the only riches she can call her own.
- Nomadic Herding.
- Livestock Ranching.
- Shifting Cultivation.
- Intensive Subsistence Farming.
- Commercial Plantations.
- Mediterranean Agriculture.
- Commercial Grain Farming.
Modern farming methods refer to the agricultural production system characterized by the high inputs of capital, labour, heavy usage of farm machinery such as threshers, harvesters, winnowing machine, heavy usage of technology such as selective breeding, pesticides, chemical fertilizers and insecticides.
Modern agriculture
- Agribusiness.
- Intensive farming.
- Organic farming.
- Precision agriculture.
- Smart farming.
- Sustainable agriculture.
What are these modern agricultural methods?
- Genetic manipulation.
- Intensive tillage.
- Monoculture.
- Use of synthetic fertilizers.
- irrigation technologies.
- chemical pest control.
The excessive use of chemicals by the help of machines reduces the fertility of the land. Lack of practical knowledge the farmers cant handle the machines properly. While the cost of maintenance is very high. Overuse of machines may lead to environmental damage.It is efficient but has many side effects and drawbacks.
By some calculations, the planet's population is projected to increase almost 20% to 9.15 billion by 2050. Such growth will present immense challenges. In 2012, the Food and Agriculture Organization of the United Nations reported agricultural production would have to grow by 60% to meet this increased demand for food.
Modern agriculture uses advanced technology , such as plant breeding techniques and pesticides. Seeds that are hybrids may be used and other gene editing techniques applied. Modern agriculture is less labor intensive than traditional agriculture because there is a greater reliance on machinery .
Farming is an important job, but it can be dangerous. Hazards on farms include toxic gases from fermenting crops and animal manure, chemicals in pesticides and fertilizers, high levels of dust, and infected animals that can spread diseases.
Agriculture contributes to climate change both by anthropogenic emissions of greenhouse gases and by the conversion of non-agricultural land such as forests into agricultural land. In 2010, agriculture, forestry and land-use change were estimated to contribute 20–25% of global annual emissions..
The crisis will impact U.S. agriculture mostly through indirect international effects rather than through changes in the U.S. economy. The slowdown of growth in foreign economies will reduce import demand for agricultural commodities, resulting in lower U.S. agricultural exports and prices for agricultural commodities.
Causes of Agricultural Pollution. Agricultural pollution predominantly arises from farming practices. Fertilizers, pesticides, herbicides, animal manure and other agro-chemicals are rich in chemical nutrients and toxic substances which are often the major sources of agricultural pollution.
Livestock farming has a vast environmental footprint. It contributes to land and water degradation, biodiversity loss, acid rain, coral reef degeneration and deforestation. Nowhere is this impact more apparent than climate change – livestock farming contributes 18% of human produced greenhouse gas emissions worldwide.
