General information on programming ET controllers can be found in Smart Irrigation Controllers: Programming Guidelines for Evapotranspiration-Based Irrigation Controllers at http://edis.ifas.ufl.edu/ae445. In the spring, when the air temperature is in the 70s in much of California, lawns need about one-half to three-quarters of an inch of water per week, Ingels said. For example, an epidemic of stem rust on wheat caused by the Ug99 lineage is currently spreading across Africa and into Asia and is causing major concerns due to crop losses of 70% or more under some conditions. [46] Approximately 40% of the world's agricultural land is seriously degraded. [47] In Africa, if current trends of soil degradation continue, the continent might be able to feed just 25% of its population by 2025, according to United Nations University's Ghana-based Institute for Natural Resources in Africa. [48] Agrarian structure is a long-term structure in the Braudelian understanding of the concept.
