The U.S. government has invested over $10 billion in counternarcotics and security efforts in Colombia since 1999. Security has improved but cocaine production has more than tripled from 2013 through 2017.

The U.S. counternarcotics approach in Colombia includes disrupting drug trafficking, destroying coca crops, and supporting alternative livelihoods for coca farmers. We found the State Department has not comprehensively reviewed this approach. Such a review could help State ensure U.S. agencies are pursuing the mix of activities with the greatest likelihood of long-term success.

We recommended State comprehensively review the U.S. approach.

What GAO Found

U.S. agencies that provide counternarcotics assistance to Colombia conduct performance monitoring of their activities, such as by tracking the hectares of coca fields eradicated and the amount of cocaine seized, but have not consistently evaluated the effectiveness of their activities in reducing the cocaine supply. The U.S. Agency for International Development (USAID) has evaluated some of its alternative development programs, but the Department of State (State), which has lead responsibility for U.S. counternarcotics efforts, has not evaluated the effectiveness of its eradication and interdiction activities, as called for by its evaluation policies. Additionally, State has not conducted a comprehensive review of the U.S. counternarcotics approach, which relies on a combination of eradication, interdiction, and alternative development. Without information about the relative benefits and limitations of these activities, the U.S. government lacks key information to determine the most effective combination of counternarcotics activities.

United States and United Nations Estimates of Cocaine Production in Colombia, 2008-2017

United States and United Nations Estimates of Cocaine Production in Colombia, 2008-2017

Notes: The United Nations and the U.S. government each produce annual estimates of the amount of coca cultivation and cocaine production in Colombia. Although their estimates show the same general trends, the United Nations and the U.S. government use different methodologies to produce their estimates, resulting in differences in the specific amounts estimated from year to year.

GAO's review of U.S. agency performance monitoring data and third-party research offers some information about the relative effectiveness of eradication, interdiction, and alternative development activities. For example, available evidence indicates that U.S.-supported eradication efforts in Colombia may not be an effective long-term approach to reduce the cocaine supply, due in part to coca growers responding to eradication by moving coca crops to national parks and other areas off limits to eradication. Agency data show that U.S.-supported interdiction efforts in Colombia seized hundreds of tons of cocaine and arrested thousands of drug traffickers, yet the net cocaine supply has increased and third-party studies have mixed findings on the long-term effectiveness of interdiction efforts. USAID evaluations indicate that alternative development programs in Colombia have provided legal economic opportunities to some rural populations previously involved in illicit crop production. However, USAID as well as third-party research suggests that alternative development requires significant and sustained investment and some programs have had design and sustainability challenges.

Why GAO Did This Study

Colombia is the world's leading producer of cocaine, with production levels more than tripling from 2013 through 2017 (see figure). The U.S. and Colombian governments have been longstanding partners in the fight against drug trafficking. Since the launch of Plan Colombia in 1999, the U.S. government has invested over $10 billion in counternarcotics efforts in Colombia. This assistance has supported a range of eradication, interdiction, and alternative development programs.

GAO was asked to review U.S. counternarcotics assistance to Colombia. This report examines (1) to what extent the U.S. government has assessed the effectiveness of its counternarcotics efforts in Colombia and (2) what is known about the effectiveness of U.S.-supported eradication, interdiction, and alternative development programs in Colombia. GAO reviewed data and documentation from U.S. agencies, performed a literature review of relevant research on counternarcotics efforts in Colombia, conducted fieldwork in Colombia, and interviewed U.S. and Colombian officials.

What GAO Recommends

GAO recommends that State, in consultation with relevant agencies, (1) evaluate the effectiveness of eradication and interdiction in reducing the cocaine supply in Colombia and (2) undertake a comprehensive review of the U.S. counternarcotics approach in Colombia that considers the relative benefits and limitations between eradication, interdiction, and alternative development efforts. State generally concurred with the recommendations.

Recommendations for Executive Action

  1. Status: Open

    Comments: State generally agreed with our recommendation. As of May 2019, State reported that it was in the process of designing an evaluation of counternarcotics efforts in Colombia, in coordination with interagency counterparts, to issue for solicitation later in 2019. We will continue to monitor State's efforts to implement this recommendation.

    Recommendation: The Secretary of State should, in consultation with other U.S. agencies involved in counternarcotics efforts in Colombia, conduct an evaluation of the long-term effectiveness of eradication and interdiction in reducing the cocaine supply. (Recommendation 1)

    Agency Affected: Department of State

  2. Status: Open

    Comments: State generally agreed with our recommendation. As of May 2019, State reported that it was in the process of designing an evaluation of counternarcotics efforts in Colombia, in coordination with interagency counterparts, to issue for solicitation later in 2019. We will continue to monitor State's efforts to implement this recommendation.

    Recommendation: The Secretary of State should, in consultation with other U.S. agencies involved in counternarcotics efforts in Colombia, undertake a comprehensive review of the U.S. counternarcotics approach in Colombia and identify what changes, if any, should be made to the types and combination of U.S. activities, taking into consideration how the relative benefits and limitations between eradication, interdiction, and alternative development may impact the effectiveness of these efforts. (Recommendation 2)

    Agency Affected: Department of State
