ENGLISH

I. Read the chapters prescribed for SA – 1 of The Diary of a Young Girl and write its book review II. Read the following passage carefully and answer the questions that follow. When Siddhartha Dominic, owner of the CGH Earth group of hotels, wanted to give back to the land he had received from, he sifted through a range of possibilities before finally zeroing in on his big idea. He would soon incorporate the “50- mile diet” in the menu of his restaurant-also called 50 Mile- at the Spice Village in Thekkady; Kerala. The idea was quite simple-source ingredients for the dishes from within a 50 mile radius. Dominic says it was a win-win concept from the word go. “It had the potential to reduce the carbon footprint, provide livelihood to local farmers and give our guests a chance to experience something different”. And the guests were, well, eating out of the palm of his hand. The food moreover was fresh and full of nutrients, which otherwise gets lost as the produce makes the journey from soil to the supermarket. The movement for locally produced food is nothing new. Initiated a few years ago by local food enthusiasts –“Locavores” – who insist on only eating food drawn from within a 100 mile radius of their home, it’s a concept that’s slowly picking up in India. “You can spot the difference in taste the moment you pop a locally grown fruit or vegetable in your mouth. It simply bursts with natural goodness that is difficult to find in commercially transported and frozen produce”. Says Ganesh, a copywriter and a diehard locavore.Most of our food now travels an average of 400 to 800 km before ending up on our plates. Besides adversely affecting health, this kind of food supply also has serious consequences on the environment and the community. In times of growing awareness about global warming and sustained living, going locavore is increasingly being seen as the “correct thing to do”. Karan Bakshi, former General Manager of Spice Village, the man who conceptualized and implemented the 50- mile concept at the hotel, says the success of the idea was also because guests became aware that they were doing their bit for the community and the environment.“Guests at the restaurant get “The Chef’s Note” showcasing the dish they have eaten, the name of the farmer who produced it and the distance of the farm from the hotel. This is signed by the chef and it’s something they can take back with them, a note that, in a way, certifies their dinner had helped reduce carbon footprint and helped the local community directly. “Other restaurants, too, are thinking along similar lines. Rajesh Wadhwa, executive chef at New Delhi’s Taj Palace, says he is planning to start with hotel’s Indian restaurant Masala Art. “If the farmers are able to sustain, we may think about the gradual shift to the concept of the main kitchen.”Wadwa’s caution underlies what may perhaps be a major setback for an otherwise great idea: implementation of the concept may not be a practical possibility everywhere. In Spice Village for instance the

forests of Periyar and the adjoining land have a rich biodiversity teeming with the native vegetables, spices and meat, with salt being perhaps being the only item sourced from outside the prescribed radius. Not all restaurants are so fortunate, especially those in big cities. A.
