The importance of horticulture in combating climate change
One of the most complicated and difficult environmental threats the world is currently facing is climate change, which has had a significant impact on ecosystems. Over the next ten years, it is expected that the average world temperature would climb by 1.5 to 2.0 °C, causing more heat waves, longer warm seasons, and shorter cold seasons.
India's unique geography, ecosystems, and climatic zones make it more susceptible to climate hazards. Due to climate change, the central Indian state of Madhya Pradesh is also enduring droughts, excessive rainfall, floods, and hailstorms. Numerous areas in Madhya Pradesh are dealing with issues including rain that comes late, leaves early, has a protracted dry period, and not enough water in reservoirs, all of which wholly adversely effect crop productivity.
Fruit crops (mango, guava, banana, oranges, papaya), vegetable crops (potato, onion, peas, tomato, brinjal, cabbage), spice crops (chilly, garlic, coriander, ginger), and flower crops are some of the most important horticultural crops farmed (marigold, rose, gladiolus). With a share of roughly 45 percent in the region, vegetable crops are the most common, followed by spices at 35 percent, fruits at 18 percent, and flowers at 2 percent.
The anticipated temperature increase is alarming because it could have a direct impact on the flowering of fruit crops like guava and mango. During the peak of the mango plant's bloom, high temperatures and low relative humidity cause higher transpiration rates, which cause dehydration and lower output. Due to the infestation of insects like fruit flies, hot and humid weather can increase the likelihood of pests and diseases.
High temperatures can also shorten the growth time for the bunch by speeding up plant maturity rates in fruits like bananas. Due to their succulent nature, vegetables are much more sensitive to high temperatures. For instance, because of decreased productivity and smaller stature, high temperatures might result in yield losses in tomato plants. In tomatoes, higher temperatures can cause ovule abortion and poor viability, bud drop, abnormal flower development, poor pollen generation, dehiscence, and viability, as well as other reproductive problems.
Low temperatures in cucumber promote the growth of female flowers, whereas high temperatures promote the growth of more male flowers, which inhibits the growth of female flowers. Reduced yields are caused by the shorter duration of onion bulb size at high temperatures.
Impact of Climate Change on horticulture crops
Little precipitation and high temperatures brought on by climate change's rapid rise in temperature have decreased horticultural crop production and market demand. Agriculture commodities including wheat, maize, and rice as well as horticultural products like saffron, walnuts, and apples have seen a decline in production in the Jammu and Kashmir regions. Due to the change and loss brought about by climate change, many cities and farmers who were known for producing certain crops as well as communities and farmers who were completely dependent on horticulture crops have been under pressure.
Conclusion
Recognizing how Climate Change is negatively affecting agricultural production should be the first step in solving the difficulties. We will be in a better position to build the solutions once we are aware of the disparities. Bringing up the developing issues can assist establish policies and methods that, when properly and successfully applied, can lead to desired results. Crops used in agriculture and horticulture could be saved using the best techniques, such as greenhouse technology and the development of heat-tolerant measures. However, before implementing these techniques, it is crucial to acknowledge the problems and difficulties caused by climate change.
