Recycling Water On Cairo's Rooftop Gardens.
ANDERSON: More and more of us are looking for ways to reduce our environmental impact, are we? As part of our "GOING GREEN" series today, we are taking you to Cairo. The one businessman is teaching urban farmers how to recycle water on the city's rooftop gardens.</s>UNIDENTIFIED FEMALE: In Egypt's capital Cairo, one environmentalist taps into the power of community to spread his green message.</s>SHERIF HOSNY, CO-FOUNDER, SCHADUF: My name is Sherif Hosny, I'm the co- founder of Schaduf.</s>UNIDENTIFIED FEMALE: Schaduf is an Arabic word for an ancient irrigation tool that is still used by farmers today. It lifts water to irrigate canals to harvest crops. Sharif's company works to lift farming to the rooftops of Cairo.</s>HOSNY: We grow all our crops hydroponically. We also use the recirculating systems, which means we save a lot on water, which of course, great for the environment and great for Egypt, because we have a shortage of water.</s>UNIDENTIFIED FEMALE: Egypt has long been called the gift of the Nile. With the river supporting around 90 percent of the country's freshwater needs. But this country along with its congested capital is in the grips of a serious water crisis. According to the United Nations, Egypt could face a critical water shortage by 2025. An issue that prompted Sherif to set up his company in 2011.</s>HOSNY: We decided we want to have -- creative a company that has an impact. Money, of course, is important, but we also said we have to have some kind of impact, environmental and social.</s>UNIDENTIFIED FEMALE: It's a simple business model. With the help of donations and microloans, residents can purchase a small flat pack farm. Schaduf install the urban garden, provide training on growing crops, and using recycled water and mineral solutions. Communities can grow cheaper, healthier produce within a few weeks. Yet, according to Sherif, growing crops is not the only part of the company's impact on society.</s>HOSNY: We thought, you know, it can be a great combination having soilless agriculture on a roof and having like low-income families working on them to generate income.</s>UNIDENTIFIED FEMALE: Since the company started, more than 500 farms have grown on the rooftops of Cairo, earning each farmer up to 600 Egyptian pounds per month, the equivalent of $35.00.</s>HOSNY: In the region, a lot of the cities face very similar challenges to Cairo. We want to expand in the Gulf and maybe other Arab countries. I think the future looks bright for this, this industry. And it's probably going to change the way farming is done in the future.</s>UNIDENTIFIED FEMALE: Saving water and sowing the seeds of food security in the region whilst helping to improve incomes for low-income families.</s>ANDERSON: I should going green or we end this program in the country where we began, Afghanistan. A photojournalist Paula Bronstein, has spent much of her career documenting the country. Before our "PARTING SHOTS" tonight, here's a collection of her strongest images.</s>PAULA BRONSTEIN, PHOTOJOURNALIST: We are looking at 15 years of work, looking at the Afghan people, and how they lived against the backdrop of a violent war and a brutal Taliban insurgency. Really focusing on the story to give voice to people who have none. I mean, some of the happier moments for me is celebrating Afghans when they're at weddings, during Nowruz, the Afghan New Year, just to be able to see Afghans enjoying life as if there was no war. As a female photojournalist, there were always difficulties working in a conservative Islamic country. You have to abide by their rules in terms of respecting the religion. When I'm photographing women inside their home, I have to get permission from whoever the man in charge was. Access remained always the biggest challenge. This is Paula Bronstein, and these are my parting shots.</s>ANDERSON: CONNECT THE WORLD. Thank you for watching.
