South American Locust Regional Management Plan

Strengthening implementation of the South American Locust Regional Management Plan to reduce the economic, social and environmental impacts of the plague in Argentina, Bolivia and Paraguay

Towards a Solution

The South American Locust Regional Management Plan aims to assist over 300,000 beneficiaries in the 72,000 affected agricultural holdings. Due to its migratory and cross-border nature, collaboration among the involved countries—Argentina, Bolivia, and Paraguay—is essential to combat this pest. Effective communication between all public and private stakeholders at both national and regional levels is pivotal.

To enhance early warning systems and decision-making, actions outlined in the Regional Plan need to be streamlined and reinforced. This will optimize monitoring, control, and data flow, minimizing the impact of the locust plague on agricultural production and the livelihoods of farmers.

Interstate coordination is crucial for locust management. In 2017, the countries, through their national phytosanitary protection agencies (NPPAs), signed an agreement to develop a technically agreed-upon South American locust regional management plan, focusing on phytosanitary surveillance in border regions, phytosanitary control, training, and communication.

The NPPAs have responded effectively to emergencies in all three countries, collaborating with global experts and acquiring the necessary technical training to combat the locust plague.

Implementation involves standardizing data capture methods, creating a regional handbook, and establishing a regional mobile monitoring system. Ultra-low volume spraying, a water-efficient technique, will be used for locust control. A consultancy will assess the economic, social, and environmental impacts of the plague and potential funding sources for its control.

These improvements will feed into a regional real-time data visualization system, aiding decision-makers. A regional AI system will manage reports and alerts, enabling easy reporting by farmers and informants, streamlining response by the NPPAs. In northeast and northwest Argentina alone, the locust plague threatens agricultural production worth USD 3.7 billion annually, excluding fruit farms, cash crops, natural pastures, and livestock forage.

Warning systems will expedite responses to threats, ensuring efficient management and the application of communication and control technologies. The strengthened Regional Plan and surveillance system may attract other threatened countries in the region (Brazil, Uruguay, Peru, etc.) to join through cooperation agreements, enhancing project sustainability.

The success of the handbook and warning systems will set the stage for managing other locust species (e.g.: Central American locust) and various plagues or diseases affecting production in these countries.
