Data or statistical facts on the situation and perspectives of agri-food systems and the impact of policies
In Peru’s Upper Huallaga basin, 73 structured farmer interviews were integrated with local station and ERA-5 data. A temperature rise of +0.2 °C per decade matched farmers’ perceptions. Increased crop water deficit and surplus volumes suggest more intense sub-daily convective rainfall, helping explain perceived changes in precipitation and wind (Serrano et al., 2025).
32% of farmers in Bolivia use irrigation, but it only covers 7% of the planted area (Castilleja et al., 2023).
61.6% of water withdrawals in Brazil come from agriculture, although water stress is low, with a value of 0.8 (OECD, 2024).
80% of deforestation, 70% of biodiversity loss and 70% of freshwater use are caused by food systems (WWF, 2022).
80% is the level of water stress in Latin America and the Caribbean, which occurs during periods varying from 3 to 12 months a year (ECLAC, 2024).
95% of Tobago's groundwater supply comes from bedrock aquifers, validating the sustainability potential of this source to meet growing agricultural demand (Govia & Roopnarine, 2024).
2 main uses have rainwater harvesting techniques in Trinidad and Tobago: residential and agricultural, as a cost-effective solution (Govia & Roopnarine, 2024).
3 key benefits of green infrastructure in Trinidad and Tobago: regulation of water supply and quality, and moderation of extreme events for agriculture (Govia & Roopnarine, 2024).
700,000 m³/day will be the projected wastewater flow for Trinidad and 30,000 m³/day for Tobago by 2035, pointing to the potential for reuse in agriculture (Govia & Roopnarine, 2024).
4 problems affect agriculture in Trinidad and Tobago: agrochemical pollution, solid waste, soil erosion and deforestation (Govia & Roopnarine, 2024).
