High grazing intensity and wide-spread woody encroachment may strongly alter soil carbon (C) and nitrogen (N) pools. However, the direction and quantity of these changes have rarely been quantified in East African savanna ecosystem. As shifts in soil C and N pools might further potentially influence climate change mitigation, we quantified and compared soil organic carbon (SOC) and total soil nitrogen (TSN) content in enclosures and communal grazing lands across varying woody cover i.e. woody encroachment levels.

A decline in minor millet cultivation rings true across much of India. Yet a country wide revival of this cereal crop is in motion. Farmers are again recognising and asserting the value of minor millets, a cereal crop that was once central to their culture. A group of farmers in Madhya Pradesh have taken strength from farmers in Tamil Nadu who have successfully brought millet back into their fields, their homes and onto plates across their region. This is a story of how learning exchanges and partnerships support amplification of succcessful initiatives.

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.

This review was commissioned to undertake an evaluation of how the Climate Change, Agriculture and Food Security (CCAFS) Theme by Region matrix is being managed to deliver on International Public Goods (IPGs) and development outcomes.

This study produces a set of maps and tables that locate significant populations of poor livestock keepers and has broadly assessed how poor livestock keeping populations are likely to change over the next 3-5 decades. The outputs of the study are based on innovative analysis using new global data sets.

The animal science systems group at Texas A & M University (TAMU) has developed a computer based beef cattle production model for use in tropical countries. This model can be used to predict animal and herd productivity under a variety of management regions in diverse environments. Economic analyses can then be made, based on these predictions.

In the sustainable intensification (SI) of smallholder agroecosystems, researchers and farmers collaborate to produce more food on land currently in cultivation, secure wellbeing in the present day, and bolster ecosystem services to sustain agricultural productivity into the future. In recent years there has been debate in the SI literature about the meaning and boundaries SI, accompanied by calls for clearly defined metrics to evaluate SI efforts. In this review, we present the current state of the literature in regards to SI metrics.
