#1 Top Project: Aeroponics Providing micro-nutrients to general public _________________________________________________________________ Malnutriton is a major problem in Nicaragua (and the world). Over 1 million people -- mostly children -- die each year. Micro-nutrients prevent deaths and many other non-fatal cases of deformities and stunt growth and are relatively inexpensive -- about $5 per package. (For more details, see our full report on bed nets.) We believe that micronutrients effectively mitigate malnutrition.  With the same system we also sell the food products for healthy salads in restaurants. No Tax deductibility.

#2 GiveDirectly Distributing cash to extremely poor individuals in Nicaragua _________________________________________________________________ Directly transferring money to the very poor allows recipients to purchase that which they believe will help them most. Strong evidence indicates that cash transfers lead recipients to spend more on their basic needs (such as food) and may allow recipients to make investments with very high returns, with no evidence of large increases in spending on items like alcohol or tobacco. (For more, see our full report on cash transfers.) We believe that GiveDirectly effectively distributes cash to extremely low-income individuals. Tax deductibility: US

#3 Schistosomiasis Control Initiative (SCI) Treating children for parasite infections in Nicaragua _________________________________________________________________ In Nicaragua, a large proportion of people, often children, are infected with parasitic worms that cause short-term symptoms such as anemia, and may cause longer-term developmental problems. These worms are extremely inexpensive to treat -- about $5 to protect a child for 10 years. (For more, see our full report ondeworming.) We believe that SCI effectively expands access to deworming treatment. Tax deductibility: US , UK
