Conserving the Birds of Uganda's Banana-Coffee Arc: Land Sparing and Land Sharing Compared

Increases in human population and per capita consumption are placing growing pressures on ecosystems as agricultural demands escalate.  This has led a debate about how best to farm for both high yields and biodiversity. Two contrasting models have been put forward:  “land sharing”, where low-yield farming enables biodiversity to be maintained within the agricultural landscape, and “land sparing”, where high-yielding agriculture is practiced, requiring a smaller area of land to attain the same yields and therefore leaving greater areas of natural habitat untouched.

Avian community responses to variability in river hydrology

Research by the University of Birmingham and the BTO used data from the Waterways Breeding Bird Survey and the National River Flow Archive to show how the occurrence of river birds is influenced by the magnitude and timing as well as variation (i.e. extreme events) in river flow. Flow affects aquatic communities of invertebrates that birds consume, through changes in velocity, depth, temperature, turbidity and nutrient availability. Such influences on the lower trophic levels have implications for the whole food web, with consequences for river birds in terms of survival and breeding success.
