These areas provide many benefits, such as helping filter nutrients that are collected as the water runs over the land helping control water during floods and providing habitat for animals. Landowners can also improve water quality by preserving wetland and riparian areas, which are spaces between land and the waterway, ideally filled with native grasses, shrubs and trees. A healthy soil will hold more moisture and grow better crops. It also provides more organic matter, improving soil health. 8В This helps slow water movement, reducing the risk of erosion. They can remotely turn their irrigation systems on and off to use water more efficiently while increasing crop yields.ДЄnother best management practice is conservation tillage, which involves covering at least 30 percent of the soil surface with crop residues left after harvesting. They can get live weather updates and calculate how much water is needed for the day. Farmers can use their phones to gain information on the soil moisture content of their crops. Technology plays a key role in water management. In countries like Canada or the United States, pivot irrigation is a great way to apply water at specific times of the day. This minimizes water losses from evaporation and increases yields by as much as 90 percent compared to plants only receiving rainwater. They also utilize drip irrigation where water is delivered close to plant roots through a pipe, drop by drop. Too much and water is wasted as runoff.ДЇor example, in countries like Kenya where rainfall can be unpredictable, farmers collect and store rainwater to reuse when itвЂ™s needed most. ItвЂ™s about using the right amounts at the times when crops need water most. Through advances in technology and improved best management practices, farmers try to ensure that crops have the right amount of water while conserving water and maintaining water quality. The unpredictable availability of water is making it harder for farmers to grow crops, putting our food supply at risk. In some parts of the world, the climate is becoming drier, and in others it is becoming wetter. As our climate changes, the weather is becoming more extreme and unpredictable. 6В This calculation includes the water required to grow the raw materials, process them and manufacture the final product.

4В For example, it takes 435 liters (115 gallons) of water to grow enough wheat to make just one loaf of bread 5В and about 11,000 liters (2,900 gallons) to make a pair of blue jeans.

In fact, nearly three-quarters of the worldвЂ™s freshwater is used in agriculture to produce the food, fiber and products that we need to live. Water is an essential part of agriculture. 3 Water is essential and needs to be conserved and protected. 2В With economic and population growth in those areas, more than half the worldвЂ™s predicted population will face water shortage by 2050 if nothing is done. Today, about 1.3 billion people live in regions with an uncertain supply of fresh water. As our population grows, there is even more pressure on our limited supplies. For example, we need water to make the cars that get us to school and to grow the food that we eat. Water is essential, not just for drinking and keeping clean, but throughout our lives. Only 0.3 percent of that is accessible for us to use. Only 2.5 percent of EarthвЂ™s water is freshwater, found in glaciers and polar ice caps, groundwater, surface water such as lakes, ponds and rivers, and in the atmosphere. However, we can only use a tiny fraction of it. All the blue that you see is water, and it makes up 70 percent of EarthвЂ™s surface. Take Action: Project-based Learning and Program Summary.Lesson 1: Introduction to Sustainable Agriculture.See the links below for the remaining lessons: These lessons can be taught individually or as an entire unit. As students interact with each family, they learn the role of best management practices in feeding the world, reducing environmental impacts, and improving social performance through greater access to education, medical care and community infrastructure. The online simulation contextualizes these concepts as students experience the lives of three farm families in Kenya, India and Canada. The lessons engage students with the important concepts regarding sustainable agriculture. Journey 2050 takes students on a virtual simulation that explores world food sustainability and answers the question, 'How will we sustainably feedВ nearly 10 billion people by the year 2050?' The lesson plans and online simulation program allows students to make decisions on a virtual farm and witness their impact on society, the environment and the economy at a local and global scale.
