Panaji: Even when the impact of climate change intensifies globally, increased water runoff because of conceitization and flooding which is increased in extreme weather events is likely to be a double whammy for declining agriculture.
Paddy, like the main plant cave, seeing the resurrection, with mechanization facilitating labor costs and the problem of farmers.
But given the wavy topography and disaster conditions created by unsustainable developments, the impact of climate change is likely to be strengthened, especially in the coastal and midland plains.
The Coastal Plains – becomes more susceptible to direct hazards – has greater agricultural patches.
Bicholim, Ponda and Quepem also have fairly large rice fields, who also organize vegetables and other plants, according to the season.
For Goa, relying externally because of the food, floods can even reduce the shrink area, worsen threats to food security.
“Paddy fields in the coastal plains (especially Bardez, Tiswadi and Salcete) and the Khazan landed on rivers, being in low and vulnerable areas, as well as the reclamation area of tidal flats, will be increasingly underwater in the future,” said N Somasundaram.
, former hydrogeologist, State Water Resources Department (WRD).
“After harvesting the rain plants, moisture on the ground and high water tables will ensure pulse plants,” Somasundaram said.
A hole in the field will help vegetable irrigation, watermelon and sweet potato, “Somasundaram said.
But the extreme weather and progressive sea level rise – estimated at around 55cm in 2100 – the possibility of disrupting this traditional practice increasing plant.
Pattern of land use that changes rapidly Responsible for its impact on agricultural land.
“Conversion of vegetation areas in Porvorim and Kadamba Highlands to the settlement zone have reduced the capacity of soil infiltration, triggering increased surface runoff during extreme weather events and floods from adjacent low-lying fields,” said the famous hydrogeologist Manoj Ibrushkar.
Floods in Mapapa may be a prime example of how climate change can strengthen unsustainable development impacts.
“In the past, water will flow in 24 hours, but now it is still three to four days while the flood area has increased,” said Tulio De Souza, Pre Siden Guirim comunidade.
With Guirim as a core area, flood water – now annual affairs – sinking extensive land in Socorro, Sangolda, Bastora, Parra, Ucassaim, Moira and Mapusa, reducing farmers to cry.
New highways and recent expansion, placing water pipes, pumphouses and other types of reclamation have buried the tar river and the flood plains for decades.
“The large channel across the national highway, including the tar river has been muddy, and the sewer level is damaged.
Expansion of the highway on the side of the guirts, especially near the Bastora Bridge, is the cost of diverting the river,” De Souza said.
Traditionally, surface runoff in Goa flows from east to west.
“The expansion of the highway in the North-South direction has blocked natural water flow and fragmented agricultural ecosystems along the Goa Beach Channel,” said Ibrüpurkar.
The mud embankment at West Bypass Margao has buryed the Sal River Flood and Fields in Nuvem and other villages.
In Poinguiniaim, a large agricultural channel witnessed prolonged flood after the construction of a new highway.
“The impact of the flood has increased for the past two to three years.
In such natural disasters, plants on the river bank, such as rice, bananas, areca and broken coconut gardens,” said Agriculture Director Nevil Alphonso.
Masive surface runoff during excessive rain in a brief spell damage agriculture.
“Such micro-climate changes can reduce crop yields and increase the growth of invasive harmful weed species,” said Ibrüpurkar.
A prolonged dry mantra that follows the moisture annoying from the top land, is needed for plant growth.
Low intensity rainfall which is widely scattered is always preferred for most plants.
An increase in temperatures around because climate change also affects agriculture.
The Department of Water Resources has suggested many steps, ranging from the floodland demargation to stop increasing floods, to plants with climate reservares.
The state action plan for climate change also recommends steps to fight its impact.
“Response (Bundh) along the river requires immediate improvement.
Identification and Explore natural mechanisms such as increasing mangrove forests or sea walls to guard against sea level increases,” said the report.
