Little of the current focus on landscape fragmentation has focused on rangelands or pastoral lands. This paper investigates the existing evidence for causes and processes of fragmentation in pastoral lands and its effects of landscapes and peoples. More conceptual work is needed on the definition of loss and fragmentation, particularly efforts to clarify fragmentation from whose (or what's) perspective.

Examines the need and methods for studying livestock markets and routinely collect time series data on prices of livestock at local, regional and terminal markets, outlining a method for setting up a systematic collection and analysis of livestock market information. Presents a simplifed livestock marketing systems model; illustrated suggestions for data analysis; and recommendations for a national organizational framework for collecting & analyzing livestock market data.

Discusses how low level aerial survey can be used to diagnose constraints within pastoral systems and the relative cost effectiveness of such operations, with particular reference to flight & sample procedures and information collection and analysis; presents some results from low-altitutde aerial survey undertaken by ILCA in Nigeria, Mali, Niger and Ethiopia.

Presents results of a 6 year study on the livestock production systems, management practices herd & flock demography in an agropastoral system in central Mali as well as reproductive performance growth rate, weights, mortality, offtake and productivity in terms of meat & milk yield of cattle & small ruminants; includes recommendations on means of improving the system and future research.

Reviews various approaches and techniques used in a number of sub-Saharan African countries to collect and analyze data on large-scale ecological changes with particular reference to remote sensing and monitoring techniques in resource inventory; suggests ways to build more effective data bases.

The first chapter gives a brief description of a pastoral production system, as envisaged by the study team and outlines the multi-disciplinary approach of the study, its sampling design and the data collected. Chapters 2 & 3 describe Kenya's biophysical and socio-economic environments, within which the Maasai livestock production system operates. The biophysical environment of the study site is described in detail in Chapter 4. Chapter 5 describes the social organization of the Maasai and how it affects their use of livestock and grazing resources.

In Cameroon, rangelands occupy about 20 % of surface area; provide critical habitat to many animal and

plant species; offer many vital goods and services to society and are home to pastoralists, agropastoralists,

crop farmers, fishermen and hunter-gatherers, who for centuries co-existed peacefully. In

recent years this harmony is being threatened by changing land use patterns, poor land use planning and

poor recognition of ownership rights. Despite efforts by state and non-state actors to improve pastoral

There is consensus that pastoral mobility is beneficial for both pastoralists and the environment. However, rapid change arising from multiple factors, including landscape fragmentation, sedentarization, and demographic drivers might affect the effectiveness of this pastoral coping strategy in times of drought. We investigate livestock mortality rates following the 2005 drought in four areas in Maasailand: the Maasai Mara, the Kitengela plains, the Amboseli, and the Simanjiro plains.
