Case Study: Panama Canal Watershed

The Panama Canal Watershed experienced significant deforestation between 1974 and 1991, with forest cover decreasing by 43 percent. In response to water scarcity risks and the operational needs of the canal, the Panama Canal Authority (ACP) and the Panamanian government implemented a combination of strict legal prohibitions, financial incentives, and active reforestation. By 2010, approximately 18,000 hectares of forest had been restored. Key success factors included the creation of the Interagency Watershed Commission (CICH) and the Environmental Economic Incentives Program, though challenges remain regarding invasive species, land tenure, and community participation.

• Between 1974 and 1991, the Panama Canal Watershed saw a 43 percent decrease in forest cover, dropping from 275,550 hectares to 157,000 hectares. Deforestation was driven by crop growth, cattle ranching, urbanization, and earlier state-led programs like the 'Conquest of the Jungle'.
• Forest restoration is critical for the canal's operation because deforestation alters water flow patterns, increasing wet season flow and decreasing dry season flow. This threatens the 52 million gallons of water released during the passage of 35–45 ships daily, which is equivalent to two-thirds of the daily water consumption of 320,000 Panamanians.
• By 2010, forest area in the watershed increased by approximately 18,000 hectares, reaching a total of 175,000 hectares. This was achieved through a shift from nonnative species (acacia and melina) used in 1987 to a mandate for native species adopted by the Panama Canal Authority in 1998.
• The Panama Canal Authority (ACP) established the Environmental Economic Incentives Program in 2010, a 20-year initiative covering 20,000 hectares with an investment of approximately 20 million balboas (U.S. $20 million). The program utilizes six modalities, including agroforestry, silvopastoralism, and commercial reforestation.
• Institutional coordination is a key success factor, with the ACP managing the watershed in coordination with the Interagency Watershed Commission (CICH), 31 local committees, and six watershed advisory councils. This structure provides a comparative advantage over other Panamanian watersheds managed solely by the Ministry of Environment.
• Ongoing ecological barriers to restoration include the invasive grass Saccharum spontaneum, which suppresses native species, increases wildfire risk, and depletes soil nutrients. Other challenges include insecure land tenure, lack of credit for smallholders, and limited community involvement in projects focused on conservation over participation.
