Architecture of the global land acquisition system: applying the tools of network science to identify key vulnerabilities

Autor: J W Seaquist, Emma Li Johansson, Kimberly A Nicholas

Publikováno v: Environmental Research Letters, Vol 9, Iss 11, p 114006 (2014)

Global land acquisitions, often dubbed ‘land grabbing’ are increasingly becoming drivers of land change. We use the tools of network science to describe the connectivity of the global acquisition system. We find that 126 countries participate in

Future supply and demand of net primary production in the Sahel

Autor: F. Sallaba, S. Olin, K. Engström, A. M. Abdi, N. Boke-Olén, V. Lehsten, J. Ardö, J. W. Seaquist

Publikováno v: Earth System Dynamics, Vol 8, Pp 1191-1221 (2017)

In the 21st century, climate change in combination with increasing demand, mainly from population growth, will exert greater pressure on the ecosystems of the Sahel to supply food and feed resources. The balance between supply and demand, defined

Disentangling the effects of climate and people on Sahel vegetation dynamics

Autor: J. W. Seaquist, T. Hickler, L. Eklundh, J. Ardö, B. W. Heumann

Publikováno v: Biogeosciences, Vol 6, Iss 3, Pp 469-477 (2009)

The Sahel belt of Africa has been the focus of intensive scientific research since the 1960s, spurred on by the chronic vulnerability of its population to recurring drought and the threat of long-term land degradation. But satellite sensors have rece

Autor: S. M. Ward, E. R. Humphreys, B. W. Heumann, P. M. Lafleur, N. M. Holden, J. W. Seaquist, N. T. Roulet, J. Connolly

Publikováno v: Biogeosciences, Vol 6, Iss 2, Pp 225-234 (2009)

We used satellite remote sensing data; fraction of photosynthetically active radiation absorbed by vegetation (fPAR) from the Moderate Resolution Imaging Spectroradiometer (MODIS) in combination with tower eddy covariance and meteorological measureme
