Spotting East African mammals in open savannah from Space

Autor: Zheng Yang Tiejun Wang Skidmore, Andrew K. Leeuw, Jan de Said, Mohammed Yahya Freer, J.

Knowledge of population dynamics is essential for managing and conserving wildlife. Traditional methods of counting wild animals such as aerial survey or ground counts not only disturb animals, but also can be labour intensive and costly. New, commercially available very high-resolution satellite...

Length of Growing Period over Africa: Variability and Trends from 30 Years of NDVI Time Series

Autor: Vrieling, A. Leeuw, Jan de Said, Mohammed Yahya

The spatial distribution of crops and farming systems in Africa is determined by the duration of the period during which crop and livestock water requirements are met. The length of growing period (LGP) is normally assessed from weather station data—scarce in large parts of Africa—or coarse-resol...

Spatial variation in the willingness to accept payments for conservation of a migratory wildlife corridor in the Athi-Kaputiei Plains, Kenya

Autor: Leeuw, Jan de Said, Mohammed Yahya Kifugo, S.C. Ogutu, Joseph O. Osano, P. Leeuw, Jan de

To be effective in promoting the conservation of migratory wildlife, recipients of payment for ecosystem services (PES) must be willing to accept payment along the entire migratory corridor. This paper investigates spatial variation in willingness to accept (WTA) payments made by the Wildlife Con...

Benefits of riverine water discharge into the Lorian Swamp, Kenya

Autor: Leeuw, Jan de Said, Mohammed Yahya Kifugo, S.C. Musyimi, Z. Mutiga, J.K. Peden, Donald G.

Use and retention of river water in African highlands deprive communities in arid lowlands of their benefits. This paper reviews information on water use in the Ewaso Ng’iro catchment, Kenya, to evaluate the effects of upstream abstraction on the Lorian Swamp, a wetland used by pastoralists downs...

Valuing ecosystem services for conservation and development purposes: A case study from Kenya

Autor: Silvestri, Silvia Zaibet, L. Said, Mohammed Yahya Kifugo, S.C.

This paper mapped and valued key inter-related drylands ecosystem services of importance to pastoralists, crop farmers, the tourism industry, conservationists, and policy planners in the Ewaso Ng’iro basin, the largest of the five major basins in Kenya. We used an ecosystem services approach wher...

Effects of irrigation and rainfall on the population dynamics of Rift Valley fever and other arbovirus mosquito vectors in the epidemic-prone Tana River County, Kenya

Autor: Sang, R. Lutomiah, J. Said, Mohammed Yahya Makio, A. Koka, H. Koskei, E. Nyunja, A. Owaka, S. Matoke-Muhia, D. Bukachi, S. Lindahl, Johanna F. Grace, Delia Bett, Bernard K.

Rift Valley fever (RVF) is a mosquito-borne viral zoonosis that is found in most regions of sub-Saharan Africa, and it affects humans, livestock, and some wild ungulates. Outbreaks are precipitated by an abundance of mosquito vectors associated with heavy persistent rainfall with flooding. We det...
