Indigenous flora conservation in Kenya.
This paper describes the environmental degradation that has occurred in Kenya since early this century, initially due to the introduction of plantation farming. Forests have been further targeted for farmland, fuel wood, building materials and hardwood species. Range land species have also become threatened due to continued infiltration of the population. The discussion considers the efforts of the Kenyan government to legislate and administrate against the further loss of natural resources and the consequent development of environmental awareness among the populace.

Spectral reflectance in the Tunesian desert
.
Satellites provide the possibility to give a synoptical view of the earth surface at regular time intervals. Satellites operating in the optical wavelengths have however as disadvantage that monitoring of the surface characteristics becomes impossible as soon as clouds are present. Deserts and desert margins are for that reason much more appropriate for monitoring by optical satellites than temperate and wet tropical areas. Potential hazards, possibilities and often inaccessibility makes use of optical remote sensing very reasonable.
