Woody Cover Fractions in African Savannas From Landsat and High-Resolution Imagery

Publikováno v: Remote Sensing, Vol 12, Iss 5, p 813 (2020)
Remote Sensing; Volume 12; Issue 5; Pages: 813

The challenge of mapping savanna vegetation has limited our understanding of the factors that shape these ecosystems at large scales. We tested seven methods for mapping savanna woody cover (trees and shrubs; WC) across 12 protected areas (PAs) in ea

Global patterns of drought deciduous phenology in semi-arid and savanna-type ecosystems

Autor: Emily Setlock, Dominick Del Ponte, Ryan Nagelkirk, Kyla M. Dahlin

Publikováno v: Ecography. 40:314-323

Seasonal variations in vegetation have direct and indirect impacts on biogeochemical cycling, net primary productivity, and the global climate. While leaf phenology in many high latitude ecosystems can be predicted based on a four-season cycle, semi-

Modeling Conservation Agriculture

Autor: Ryan Nagelkirk, Luigi Sartori, Bruno Basso

Publikováno v: Conservation Agriculture ISBN: 9783319116198

A sustainable land management should aim at high production, while minimizing risk, maintaining quality of soil and water. Excessive tillage can decrease soil carbon storage and influence the soil environment of a crop. The evaluation of the impact o
