Tóm tắt

Tầm quan trọng

Xã hội đang đối mặt với tình thế khó xử đa chiều về việc cân bằng một cách bền vững đời sống hiện tại với nhu cầu tài nguyên trong tương lai. Hiện tại, nông nghiệp đang khai thác Tầng chứa nước Ngầm Cao nguyên với mức độ vượt quá khả năng tự bù đắp tự nhiên, nhằm trồng trọt các cây trồng tưới nước và chăn nuôi gia súc để tăng cường kho lương thực toàn cầu, do đó cần có thông tin dựa trên cơ sở khoa học để hướng dẫn các quyết định. Chúng tôi giới thiệu các phương pháp mới để dự đoán xu hướng bơm nước ngầm và sản xuất ngô tưới tiêu và gia súc. Mặc dù sự suy giảm sản xuất là điều không thể tránh khỏi, nhưng phân tích kịch bản chỉ ra tác động của việc tăng cường tiết kiệm nước trong ngắn hạn, điều này sẽ kéo dài tuổi thọ khả dụng của tầng chứa nước, tăng sản lượng ròng và tạo ra sự suy giảm sản xuất ít rõ rệt hơn.
