If you think the wildly grown plants have no role to play, think again. Plants like agave, cactus (opuntia) and sitaphal, having high drought resistance and rich in nutrients, have a purpose that is yet to be fully uncovered and unleashed.

Agave is one such plant that is ‘wildly’ abused in India, in spite of its multiple benefits to nature as well as society. Its tough fibre is used to make ropes in Central America, while its cellulose is a key ingredient in Brazil’s paper industry. These apart, hecogenin, a steroid is extracted from its juice.

Similar is the case of cactus, a regenerative plant known for its ‘carefree’ growth, which is confined to field fences. Categorised as a ‘Crassulacean Acid Metabolism’ (CAM) plant, the stomata open in nights to absorb carbon dioxide and closes in the day to facilitate photosynthesis.

“It has been proved beyond doubt that natural calamities happen due to CO2 concentration and atmospheric vapour. CAM plants grown on a massive scale are the simplest solution to act as a carbon sink,” says Anumakonda Jagadeesh, Director, Nayudamma Centre for Development Alternatives, Nellore.

In an informal chat with The Hindu , he explained how the Government can saturate barren lands with these plants to maintain equilibrium and as well kick-start the rural economy. According to him, the CAM family members yield fruits having nutritional values similar to apples and pomegranates.

A cup of prickly pears contains 1.09 gm of protein, compared to a medium-sized apple’s 0.47 gm. “Israel is a major exporter of juice that fetches Rs.1,000 per litre”, he added.

While the State is grappling with the menace of water hyacinth,

Dr. Jagadeesh suggests a cheap and easy remedy. “The combination of water hyacinth and animal dung is the best source of biogas”, he pointed out.
