Increase in the number of papers in spider silk research is remarkable today. Advances in silk research provide many new insights into silk proteins and the properties. This book is a snapshot of the current state of the art of research and development on the properties and characteristics of silk and their use in medicine and industry. The field encompasses backyard silk production from ancient time to industrial methods in the modern era and includes an example of efforts to maintain silk production in Madagascar. Once revered as worth its weight in gold, silk has captured the imagination from its mythical origins onwards. The latest methods in molecular biology have opened new descriptions of the underlying properties of silk. Advances in technological innovation have created silk production by microbes as the latest breakthrough in the saga of silk research and development. The application of silk to biomaterials is now very active on the basis of excellent properties of silks including recombinant silks. We thank the authors for their contributions.

Weber and Catherine L. Craig Abstract To design a project to meet the economic needs of farmers whose livelihoods have been restricted by formation of protected areas, we modeled the potential of wild silk production to generate income while adding value to adjacent forest and agricultural zones. We project that farmers who plant 250 silkworm host plants can produce 10,000 cocoons per year and earn a median added income of 125–275 USD per year, depending on the type of silk moth reared. Income returns can increase to a median of 480 USD/household/year when other household members produce yarn and textile. Our projections for added income exceed a recent estimate for how much farmers, who have been economically displaced from the Makira Protected Area, need to maintain a subsistence lifestyle. Our findings suggest that wild silk could provide incremental income that invests local communities in forest protection and allows farmers to establish a legacy for their children. We propose that entrepreneurial approaches, such as the wild silk project described here, could be a component of an effective livelihood strategy for biodiversity conservation in areas where programs based on payments for ecosystem services cannot be effectively implemented due to extreme poverty, lack of economic infrastructure and/or political instability.

The predominant agricultural practice is tavy or swidden (Andriambolantsoa et al. 2007). Despite the fact that only about 16 % of Madagascar remains forested, deforestation continues. For example, between 1990
