Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that:
"solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies"
Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits.
"Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems"
The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported:
"The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season.
Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."
anonymous on 04 Nov 14Cerebral palsy (CP) is a general term for a group of permanent movement problems that do not get worse over time. They cause physical disability,mainly in the areas of body movement.There may also be problems with sensation, depth perception,so you use Cerebral palsy wheelchair and communication ability. Difficulty with cognition and epilepsy are found in about one-third of cases. There are subtypes including a type characterized by spasticity, a type characterized by poor coordination, and types which feature both symptoms or neither. Cerebral palsy is caused by damage to the motor control centers of the developing brain and can occur during pregnancy, during childbirth, or after birth up to about age three.About 2% of all cerebral palsy cases are believed to be due to a genetic cause.Cerebral palsy is not an infectious disease and is not contagious. Most cases are diagnosed at a young age rather than during adolescence or adulthood.CP 2 Pediatric Wheelchair is very useful for cerebral palsy person. Improvements in the care of newborns has helped reduce the number of babies who develop cerebral palsy and increased the survival of those with very low birth weights.There is no cure, with efforts attempting to treat and prevent complications. It occurs in about 2.1 per 1,000 live births.Physical therapy may help. Cerebral refers to the cerebrum, which is the affected area of the brain. The disorder may often involve connections between the cortex and other parts of the brain such as the cerebellum. The root word "palsy" means "paralysis". In medicine, this is often used in reference to the paralysis or weakness that often accompanies nerve damage, loss of sensation or muscle disorders involving uncontrollable movements such as trembling or shaking.
