How climate impacts on agriculture food supply?

                                     

   The world population is expected to grow to almost 10 billion by almost 2050. with 3 billion more mouths to feed, and the growing desire of the middle class for meat and dairy in developing countries, global demand for food could increase by between 59 and 98 percent. This means that agriculture around the world needs to step up production and increase the production of the yields. But scientists say that impacts of climate change -higher temp, extreme whether decreasing the quantity of food supply.

                                                                   

      Weather extremes

   Eighty percent of the world crops are rainfed, so most farmers depend on the predictable weather agriculture has adapted to in order to produce their crops. However, climate change is alternating rainfall patterns around the world.

   When temperatures rise,the warmer air holds more moisture and can make precipitation more intense.which is becoming more common can directly damage crops, resulting in decreased yields.

   This is happening in major food-producing regions such as the India, USA, Iran Iraq.

                                            

       Rising temperatures

   Global warming may benefit certain crops, such as potatoes in India and rice in West Africa, and enable some farmers to grow new crops that only thrive in warmer areas today.

    The ultimate effects of rising heat depend on each crop's optimal range of temperature for growth and reproduction. If temperature exceed this range, yields will drop because heat stress can disrupt a plant's pollination, flowering, root development, and growth stages.

climate effetcs on agricuture systems?

                                                    

     The positive impacts of global warming include the increase in crop productivity due to the fertilization effect caused by the increase in carbon dioxide concentration in the atmosphere, expansion of the areas available for the production of tropical and subtropical crops, expansion of two crops farming due to the increased.

     For each plant variety, there is an optimal temperature for vegetative growth, with growth dropping off as temperature increases or decreases. similarly, there is a range of temperatures at which a plant will produce seed.

     Despite technology advances, such as improved varieties, generally modified organisms, and irrigation systems, the weather is still a key factor in agriculture productivity, as well as soil properties and natural communities.

     The effect of climate on agriculture is related to variabilities in local climates rather than in global climates patterns.

     Climate change induced by increasing greenhouse gases is likely to affect crops differently from region to region.

                                                                

     In long terms, climate change could affect agriculture in several ways:

• productivity, in terms of quantity and quality of crops.
• agriculture practices, through changes in water use and agriculture inputs such as insecticides and fertilizers. 
• environmental effects, in particular in the relation to frequency and intensity of soil drought,soil erosion, reduction of crop diversity.
• rural space, though the loss and gain of cultivated land, land speculation, land renunciation, and hydraulic amenities.

what are the importance of fertilizers?

                                                 

It is very difficult to meet the demands of the increasing population with much fewer resources.loss of soil fertility, pests, and lack of nutrients have resulted in a decrease in agriculture production. This has increased the importance of fertilizer in agriculture.

Fertilizer can be important to the plants in the following ways:

• Fertilizer improves the water holding capacity of the plants and increases root depth.
• The potassium content present in the fertilizer strengthens the stews and stalk of the plants.
• Fertilizer increase plants tolerance towards pests.
• The phosphorus present in the fertilizer helps in the faster development of roots and the formation of seeds in the plants.
• Nitrogen in the fertilizer enhances the growth of the plants which can be characterized by the green color of the plants.

They also destroy pathogenic components responsible for causing disease in plants. acetobacter and rhizobium are two such widely used biofertilizers.

what are the benefits of fertilizers?

                                                         

     Advantages of fertilizer

• It increases crop yields and also improves poor quality land.
• Fertilizers used to improve soil health.
• Fertilizers are so so useful for crops.
• Manure improves soil texture, recycles nitrogen, and essential bacteria.
• Pasture is improved so animals fatten up quicker.
• Once marshland is drained, fertilizer can help reclaim that land for pasture.
• Soil structure is improved and as a result, the soil's ability to hold onto water and nutrients increases.
• Also, fertilizer also helps for crops so very very fast increase crops.
• They are predictable and reliable.
• They have rapid effects on the crops.
• They are easy to transport, store, and apply.

                                                     

       Disadvantage of fertilizer

• They are expensive.
• Excessive use of fertilizer damages the plants and reduces soil fertility.
• Long term use reduces the microbial activity and disturbs the PH of the soil.

                                                           

Types of fertilizers?

  

                                          

           there are two  types of fertilizers that are mentioned below:

                                                      

    1-Inorganic fertilizers

     Inorganic fertilizer is a chemical fertilizer that contains nutrient elements for the growth of crops made by chemical means. inorganic fertilizers used many farmers right now but it's dangerous for our soil.in India, so many people used this one fertilizer but those don't have any idea how we grow crops our farms after 10 years. The inorganic fertilizers are of the types following types:

 

     Nitrogen fertilizer,

     Phosphorus fertilizer.

                                                           

    2-Organic fertilizers

     Organic fertilizers are natural fertilizers obtained from plants and animals.it enriches the soil with carbonic compounds essential for plant growth. organic fertilizer increase the organic matter content of the soil, promotes the reproduction of microorganisms and changes the physical and chemical properties of the soil.

     It is considered to be obtained to be one of the main nutrients for green food.organic fertilizers are one of the best fertilizers I have ever ever seen.

     Organic fertilizers are one of the most used fertilizers at this time and its very very useful for farming.
