  3. 3. INTRODUCTION One of the major challenges facing humans is to provide an good standard of Living for present and future generations: Proper food ,water ,energy , safe Shelter and a healthy environment. But , Global Environmental issues such as land Degradation, loss of Biodiversity , Ozone layer depletion along with human-induced climatic change , threatens our ability to meet the Basic human needs.
  4. 4. BRIEF OVERVIEW
  5. 5. CLIMATIC CHANGE Climatic Change is one of the most serious environmental threats facing mankind worldwide. It affects agriculture in several ways , including its direct impact in food production.
  6. 6. At the same time, intruding seas contaminate groundwater in coastal communities. Ocean acidification and changes in weather patterns alter ecosystems and their capacity to provide goods and services to human communities. Soil Moisture content affected Soil erosion including washing away Soil productivity ✓ reduced ✓ capacity to grow and sustain same crop every year not certain, resulting in low yield or crop failure . • Major calamity like floods, cyclone/tornado , cloud burst etc • Unexpected change in weather pattern during monsoon season like delayed rain, long intervals for rain or heavy rain – flood has already affecting Horticulture crops. There are three kinds of impact of change in climate
  7. 7. WATER POLLUTION & INDUSTRIAL EFFLUENTS IN NEARY BY LAKE MAJOR CONTRIBUTER OF THE PROBLEM FACED BY FARMERS
  8. 8. CLIMATE CHANGE AND WATER CYCLE • Irrigation problems - over-irrigation affects water table and aquifers; under-irrigation leads to increased soil salinity. • Underground water resources are reducing due to high discharge by tube wells –for agriculture and more for washrooms in new urban enclaves. • Increased competition for water resources by expanding industries, urban areas -drives away water even from irrigation dams. • Increase in temperature results in higher evaporation rate and reduced water availability. Further reducing “Soil Moisture” directly impacting on crop productivity and its sustainability. • Rise in sea – level is already being experienced in villages of Dandi – Navsari, Cambay – Anand resulting in direct loss of agri. land. • Inundation from flood – reduces arable land or wipe out surface soil. 8
  9. 9. 9 Climate change and its impact on water cycle at local level Element of Water Cycle Climate Change Annual precipitation Expected to increase globally during the 21st Century, with potentially great spatial variations Inter-annual variations in precipitations Expected to increase everywhere Seasonal variability of rainfall • Expected to increase everywhere • Delayed monsoon • Interim delay within season Soil moisture stress (droughts) Moisture stress to generally increase as a result of increasing variability of rainfall distribution (longer periods without rain) and increasing temperatures and deplete soil moisture faster than natural vegetation Floods Increased as a result of increasing frequency and intensity of extreme rainfall events. Flood intensity can affect standing crops, wash away upper fertile crust of soil and cause soil erosion (Navsari District)
  10. 10. BURNING OF CROPS DUE TO HEAT WAVE SOURCE:INTERNET(BING)
  11. 11. ACID RAIN CROPS OF VILLAGES NEAR TO METROPOLITAN CITIES ARE HIGHLY EFFECTED BY ACID RAIN CAUSED DUE TO DANGEROUS GASES LIKE CARBON MONO- OXIDE, SULPHUR DI- OXIDE,LEAD & DUST PARTICLES IN ATMOSPHERE.
  12. 12. WATER SCARCITY DUE TO TIGHT COMPETITION BETWEEN INDUSTRIALISTS MOST OF THE WATER RESOURCES ARE USED BY FACTORIES AND INDUSTRIES . WHICH BECOME HUGE HEADCHE FOR FARMERS AS CROPS COULD NOT GET ENOUGH WATER TO FULLFILL THEIR REQUIREMENT. SOMETIMES EVEN DROUGHTS.
  13. 13. SOIL DEGRADATION & LANDPOLLUTION over-irrigation affects water table and aquifers; under-irrigation leads to increased soil salinity. Plastic and other commercial waste leads to pollution over land.
  14. 14. 21st Century Challenges- Developing Nations Environment Air Pollution due to ◦ Increased no. of vehicle ◦ Unchecked emissions by the industries •Dumping of Industrial waste •Hazardous industries •Lop sided development ◦ Challenge for flora and fauna •Dumping of untreated effluents into the rivers and seas Presentation Title
