  CLIMATE is: Long term Widearea Measured over long spans of time Seasonal changes CLIMATE is the average of many year’s weather observation

  • Climate changerefers to changes in weather conditions over a long period of time. • Usually refers to changes forced by human activities that change the atmosphere. • It is very slow and gradual change in weather.

  Worldwide, people arepaying serious attention to climate change. Because so many systems are tied to climate, such as, • People • Plants and animals live • Food production • Availability and use of water • Health Risks
• 6.
  • Rise intemperature – Maximum temperature – Optimum temperature – Minimum temperature • Global Warming – Increase in temperature
• 7.
  • Acid Rain –Acid rain burn and damage the whole plant or crop especially leaves causing lower production. • Ozone Depletion – UV Rays hit the plants causing damage to the plant leaves and also causing serious problems to Human beings
• 8.
  • Melting ofGlaciers – Causing Floods and low availability of water through out the year for irrigation • Extreme drought – Due to Variability in temperature and rain patterns, extreme drought occurs
• 9.
  • Atmospheric Gases –Green house gases, Change in concentration of atmospheric gases increase or decrease the activity of plants • Soil Conditions – Change in soil like soil Moisture, air , temperature, pH, organisms
• 10.
  • Precipitation – Changingrainfall patterns are likely to cause severe water shortages and/or flooding as well as accelerate land degradation – Change in precipitation amount effects the performance of the crop. • Atmospheric Humidity

  All these effectsthat effect the crop ultimately effect crop final yield or crop productivity and cause decline in crop productivity

  “Food security existswhen all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life”. Food Insecurity A situation that exists when people lack secure access to sufficient amounts of safe and nutritious food for normal growth and development and an active and health life. It may be caused by the unavailability of food, insufficient purchasing power, inappropriate distribution or inadequate use of food at the household level.

  Due all abovediscussed climate factors cause decrease in crop production, which results in small quantity of food for people, lower will be the Food security. Some other Reasons Due to which people not get food • Population increasing very rapidly while the production not increasing as much which make the food difficult for people. • Prices of food is also very important factor for food security, more prices of food people not able to buy food. • Transportation of food, if food not move or transport to the areas where food less in quantity it severely threaten the Food Security
