How do biofuels affect food security?
If biofuels are produced from feedstocks that would have been used for food, then biofuels directly reduce potential food supplies. This reduction occurs even if feedstock price increases result in an expansion of supply because the expanded feedstock supply will typically reduce the supply of other food crops.
What are the negative impacts of food security?
The reasons why people experience food insecurity include: a lack of resources (including financial resources and other resources such as transport); lack of access to nutritious food at affordable prices, lack of access to food due to geographical isolation; and lack of motivation or knowledge about a nutritious diet.
What are the problems of food security in India?
Despite the achievement of national food self-sufficiency, new challenges have emerged: Slowing agriculture growth, climate change, land degradation and shrinking bio-diversity. Large tracts of farmlands in India have become barren due to imbalanced fertiliser use and excessive use of a single fertiliser, urea.
How does biomass affect food production?
Besides competition with food and feed, increased use of biomass also has its effects on land use and water availability. Due to high dependence of the global food sector on fossil fuels the volatility of energy markets can have a potentially significant impact on food prices leading to increasing food insecurity.
What are the factors that affect food security?
Multiple factors are responsible for food insecurity worldwide, including population growth, climate change, increasing cost of food, unemployment, poverty, and loss of biodiversity (10).
What is the effect of biofuels on food prices?
The primary impact of biofuels on food inflation is from increases in the farm prices of commodities that contribute to producing our food supply, like corn, soybean meal, soy- bean oil, wheat, barley, and oats. Farm prices are largely determined by supply and de- mand.
How does food security affect the environment?
Food insecurity directly leads to soil erosion. This is because in many LICs the most fertile land is used for growing cash crops. The growth of cash crops places a significant demand for water for irrigation, causing water shortages for local farmers. …
What are the effects of food security?
This research has found that food insecurity is associated with increased risks of some birth defects, 5 anemia, 6,7 lower nutrient intakes, 8 cognitive problems, 9 and aggression and anxiety.
Why food security is a problem?
The main threats to food security are (1) world population growth, (2) the increase demand for food, (3) food price, (4) the disappearance of the variety of agricultural plant species (4) the increase in the area of scarcity water and the limitation of the availability of land and (5) the food losses and food waste.
How is biomass energy negative to the environment?
When we burn biomass for heat or electricity, it releases carbon dioxide into the atmosphere. If companies burn trees at a faster rate than they’re being re-planted and grown or burning trees that would otherwise be left untouched in a forest, the carbon neutrality is compromised.
Which of the following is a disadvantage of renewable energy?
Unreliable supply
The correct answer is option (B) Unreliable supply. The major disadvantage of renewable energy sources is the unreliable supply.
What is the food security bill of India?
The Union Cabinet has approved the Draft National Food Security Bill. It seeks to provide subsidized food grains to over half of India’s 1.2 billion population. The bill was presented to parliament and has been referred to standing committee.
Are there any biomass power plants in India?
Biomass power plants in India are based mostly on agricultural wastes. Gasifier-based power plants are providing a great solution for off-grid decentralized power and are lighting homes in several Indian states.
What are the disadvantages of burning biomass fuels?
Biomass fuels are mainly burned on inefficient open fires and traditional stoves. In many cases, the demand for biomass fuels far outweighs sustainable supply. This can contribute to deforestation, land degradation and desertification. Unclean burning leads to emissions.
Why is there no investment in biomass sector?
Government policy is the biggest factor behind lack of investment in biopower sector in states with high biomass potential. Defragmented nature of agricultural lands do not allow high mechanization which results in reduction of efficiency and increase in procurement cost.
