The sector suffers from low-scale, stagnating yields of inland and freshwater aquaculture, and poor infrastructure such as cold storage facilities, leading to an estimated 15-20 per cent post-harvest loss. The access to quality seed and feed for fish farming coupled with inadequate availability of credit makes the poor fisher communities not to invest in fish … Read more

Constituting about 6.3% of the global fish production, the sector contributes to 1.1% of the GDP and 5.15% of the agricultural GDP.  There are two branches of fishery sector namely Inland Fisheries and Marine Fisheries. The total fish production has nearly 65% contribution from the inland sector and rest form marine fishing.  Fish and fish … Read more

The Western Ghats are the mountain groups running parallel to the western coast of the Indian peninsula. The Ghats is well known for its biodiversity, where we can find a variety of flora and fauna. Mountain range starts around the border of Gujarat and Maharashtra, to the south of river Tapti. Runs through the states of … Read more

: Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”   Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to … Read more

Tides are great bulges of water caused by the gravity of the moon and the sun. Attracted by gravity, these bulges move around the earth’s ocean, causing water level to rise and fall. There are two main tides that are higher or lower than average. They occur twice monthly and are called neap and spring … Read more

Negatives of Interlinking of rivers: This entails environmental cost. Interlinking would destroy water bodies as each river has unique flora and fauna based on its ecology. Mixing of waters will adversely affect this uniqueness, producing unforeseen consequences. Interlinking will lead to submergence of forest. This will worsen climate change. Forest, which act as carbon sinks … Read more

The atmosphere is made up of different types of gases, water vapors and dust particles. The composition of the atmosphere is not static. It changes according to the time and place.   Water vapor is unique in that its concentration varies from 0-4% of the atmosphere depending on where you are and what time of … Read more

When two large air masses meet, the boundary that separates them is called a front. Fronts represent fairly abrupt transitions between two large air masses.  This means that when two different bodies of air come together, they do not readily mix. Rather, each body of air will retain its individual properties, and a boundary forms … Read more

Coral reefs are built by and made up of thousands of tiny animals—coral “polyps”—that are relatedto anemones and jellyfish.   Different types of coral reefs:   Fringing reefs are reefs that grow directly from a shore. They are located very close to land,and often form a shallow lagoon between the beach and the main body … Read more

Rainwater harvesting is the process to capture and store rainfall for its efficient utilization and conservation to control its runoff, evaporation and seepage. Some of the benefits of rainwater harvesting are: It increases water availability It checks the declining water table It is environmentally friendly It improves the quality of groundwater through dilution, mainly of … Read more
