Winners and Losers as the Climate Changes

Heat, drought, smog, and car and power plant emissions motivate a search for ways to deal with the climate changes they are causing.

      Cosmetic experts, for example, have found plants that purify the skin from pollutants and protect it from sun damage. Moringa seeds from trees that purify water where they grow in Africa and Asia are the secret ingredients in Vichy's Purete Thermale, a cleansing gel that removes pollution's impurities from the skin.

     Leila Janah wondered how women in Uganda managed to have lovely, unwrinkled skin despite their country's sun-soaked environment. She discovered their secret was a rare strain of African nilotica shea nuts with an extra concentration of healthy fatty acids that they purchased in a market in Gulu, Uganda. Inspired by this find, she developed a high-end beauty cream line, LXMI, named for the Hindu goddess of beauty and prosperity. Her creams contain not only organic cold-pressed butter from Gulu's shea nuts but also antioxidant fighting Ndali vanilla and Nile-grown hibiscus flowers known to plump and smooth the skin. Perhaps best of all, because LXMI is a high-priced brand that will be sold at Sephora, Janah is able to pay a dignified living wage to the women who harvest the raw materials in her creams.

      Drought has launched many a scheme, including an ill-advised one to drag an iceberg south, to provide water for farmers who are said to account for 69% of the water used around the world. Pimpri Sandas in India is among the world's villages that are watering their crops with unfiltered rainwater collected in tanks on billboards designed by Kinetic. Once a tank is full, water sensor technology sends a text message to a mobile phone that alerts a tanker to pick up and deliver the water. In India, Vodafone, owner of the billboards, funds the entire process. Other businesses, such as Hindustan Unilever and Reliance Industries, have constructed dams and ponds to help communities conserve water.

     What do frustrated farmers do when their crops die from drought and they go deeper into debt year after year? They move to cities where the UN estimates two-thirds of the world's population will live by 2050. This coming migration emphasizes the importance of the growing urban farming movement which, unfortunately, can produce too little and be too expensive for many displaced farmers. Nevertheless, it is worth examining the option of producing crops closer to where they are consumed. This process reduces pollution from trucking, a health benefit as well as a way to reduce climate warming carbon emissions. And urban farms also absorb rainwater and prevent sewer overflow from polluting rivers and lakes.

     City farms can be as simple as outside planter boxes or black pond liners filled with soil. A variety of crops can be planted to determine which are best suited for local conditions, including natural rainfall rather than irrigation. More complicated urban farms rely on greenhouses, earthworms, compost, and recycled water, that is, aquaponics (for more details, see the earlier post, "Exotic Farming."), where filtered water from tanks of edible fish water crops. In some cases, computers monitor water levels, nutrient concentration, and ideal temperatures for different crops.

     Overall, efforts to increase yields by planting crops that can withstand changes in traditional heat and rain conditions have not been promising. While cross-breeding created hybrid maize seeds that mature over shorter periods and use water more efficiently, sales are expensive and not widespread. Hybrid seeds have to be purchased each year rather than grown from the seeds of earlier crops, and since fake and falsely labeled seeds have been sold as drought-resistant, the new seeds gained a reputation as unreliable.

   

   

   

All I Want for Christmas Is Seeds

Who knew elves occasionally take a break from making toys to store seeds in Santa's warehouse. Although many put Syria on their naughty lists, in October, 2015 the Svalbard global seed vault half way between the north pole and Norway responded to an urgent request from the International Center for Agricultural Research in Dry Areas (Icarda) and sent the 128 crates of wheat, barley lentil, chickpea, fava bean, pea, and legume seeds Syria needed.

     After seeds for another 70,000 crops were added to the Global Seed Vault in 2018, Svalbard now stores 1,059,646 seeds. 

     Svalbard, known as the "Noah's Ark of seeds," is just one of the storehouses for the diversity of seeds needed to grow fruits, vegetables, and grains; the collections of plants, like apples and grapes, that are not cultivated from seeds; and even the genetic material essential to maintain the bees that pollinate many crops.

     Individual farmers also are essential in the process of ensuring a lasting food supply. On one of his "Parts Unknown" TV programs, David Bourdain found restaurant owners in the US South have been searching for the seeds that grew foods popular before the US Civil War. They located seeds that had come down through the families of former slaves, when war wiped out the seeds held by plantation owners. When kids start collecting and drying seeds for diverse crops, they also will be getting involved in the vital task of protecting the world's food supply.

 Why is the world's food supply in danger? There are many reasons:

• Wars destroy farms. Research stations in Lebanon and Morocco are working to produce seeds and saplings to resupply Syria's farmers.
• Globalization of agriculture has concentrated seed production in companies that abandon many plant varieties in order to produce uniform, high-yield varieties. (See the earlier post, "World (Food) Expo. Hybrid Crops & New Farming Practices.")
• Pests and diseases can wipe out crops. (See the earlier post, "The Bees and the Birds.")
• Global warming has reduced the area suitable for farming. (See the earlier post, "Coffee Prices Going Up; Allowances Going Down?")
• Farmers have moved to urban areas to find work.
• Without a market, farmers have stopped growing foods that have gone out of favor when diets shifted to wheat, rice, potatoes, maize, soybeans, and palm oil.
• Deforestation has removed forests where plants thrive and evolve.

Kids used to get oranges and apples in their Christmas stockings. To be sure these fruits continue to exist, the world is counting on Santa to bring these goodies along with toys and candy.
