Record global temperature in 2024 and impacts on P

20/11/2025 Go to Evidence

20.29 °C was the global average temperature recorded in 2024, with an anomaly of +1.18 °C (SENAMHI, 2024). This thermal increase is reflected in Peru through a higher frequency and intensity of droughts, floods, heat waves, cold spells, and landslides, affecting ecosystems, infrastructure, and productive sectors.

Impact of agriculture on forests

19/09/2025 Go to Evidence

The study assesses the impact of converting Amazonian forests to agricultural land in the Peruvian Amazon, analyzing how this transition affects soil organic carbon, total nitrogen, and available potassium. The results show a significant decrease in these essential components, reaching critical levels that compromise fertility, agricultural productivity, and ecological sustainability (Solórzano et al., 2025).

62.7% of bird species and 77.7% of mammals gain habitat from the abandonment of cropland, but 74.2% and 86.3% would have benefited even more in the absence of recultivation.

Sustainable agriculture

20/09/2024 Go to Evidence

USD 4.3 trillion in 2030 could be generated in health, economic and environmental benefits by investing in low-emission agriculture and land-use transformation, with a 16 to 1 return on costs (Sutton, Lotsch & Prasann, 2024).

Efficient land use

85 gigatons of CO₂ could be sequestered with efficient land use, equivalent to more than 1.5 years of global emissions, with no negative economic impact (Sutton, Lotsch & Prasann, 2024).

Changes in land use

One-third of the global land area has been affected by land use changes since 1960, with phases of acceleration (1960-2005) and deceleration (2006-2019) in these changes (USDA, 2024).
