Hypothesis

How do land use and land cover changes affect climate variability in the Bilate River Basin over the past 30 years?

Conclusion

The study found that significant land use changes, particularly deforestation and agricultural expansion, have led to notable climate variability in the Bilate River Basin.

Supporting Evidence

  • Forest cover in the Bilate River Basin decreased from 50.5% in 1994 to 29.1% in 2024.
  • Agricultural land increased from 47.1% to 60.6% over the same period.
  • Significant negative trends in rainfall were observed in the upper catchment.
  • Temperature trends showed significant increases, particularly in the upper catchment.

Takeaway

This study shows that when people change the land, like cutting down trees or farming more, it can change the weather in that area.

Methodology

The study used satellite imagery and meteorological data to analyze land use changes and their effects on climate variability over 30 years.

Limitations

The study may not account for all external factors influencing climate variability beyond land use changes.
