The Challenge

Bolivia is a prominent wintering ground for Bobolinks; tens to hundreds of thousands of this long-distance migrant can feed in a single rice field. Their presence in farm fields has made them the object of pest control measures. The pesticide of choice for rice farmers in Bolivia is monochrotophos, an organophosphate descended from nerve gases developed in WWII that is highly toxic to birds and humans. Bobolink populations have declined by 50% in the last 40 years in part due to pesticide use.

ABC aided in temporarily banning monocrotophos in Bolivia starting in December 2010.

ABC Results Button

ABC has helped document the devastating effects of monochrotophos on Bobolink populations.

ABC Results Button ABC has worked closely with The National Service of Food Health and Safety of Bolivia (SENASAG) to ban importation of the deadly pesticide.
ABC Results Button ABC gained a similar ban for this pesticide in Argentina to protect the Swainson’s Hawk.


What Next?

What Next Button Bolivia to formally sign “No Consent” import decision for monocrotophos.
What Next Button Assist Bolivia in capacity building for monitoring pesticide use its impact on the environment and human health.
What Next Button Develop means to help Bolivia transport over 437 tons of stockpiled pesticides to Brazil for disposal. These stockpiles are deteriorating and pose a hazard to human health and the environment.
