- Description: The importance of non-timber forest products (NTFPs) in rural livelihoods in developing countries has become widely acknowledged over the last decade or so within the research and, increasingly, policy arenas, on the basis of numerous studies from around the world. Indeed, there has been a tenfold increase in the annual number of research papers published over the last 20 years (Figure 1.1). Most of these studies are from developing countries, but they do include developed countries (e.g. Kim et al. 2012, Poe et al. 2013, Sténs and Sandström 2013). Additionally, most are from rural areas, albeit with a smattering from urban settings (e.g. Kilchling et al. 2009, Poe et al. 2013, Kaoma and Shackleton 2014), although with increasing urbanization this distinction is blurred with significant markets for rural NTFPs imported into towns and cities (Lewis 2008, Padoch et al. 2008, McMullin et al. 2012). Two pertinent findings of many of these studies is that NTFPs generally contribute in many different ways to local livelihoods (see Chapter 2) and that when translated into income terms many households earn a significant proportion of their income (cash and/or non-cash) from NTFPs (Shackleton et al. 2007, Angelsen et al. 2014). In other words, they are not simply minor products of little value, but rather they are vital components of livelihoods, and in some instances, of local and regional economies. This requires that they, and the land on which they are found, are managed in a responsible manner to ensure that these livelihood benefits continue to accrue to rural, and often impoverished, people.

- Description: The balance between cellular lineages can be controlled by reactive oxygen species (ROS). Cellular differentiation into adipocytes is highly dependent on the production of ROS to initiate the process through activation of multiple interlinked factors that stimulate mitotic clonal expansion and cellular maturation. The signal transducer and activator of transcription family of signaling proteins have accepted roles in adipogenesis and associated lipogenesis. Non-canonical mitochondrial localization of STAT3 and other members of the STAT family however opens up new avenues for investigation of its role in the aforementioned processes. Following recent observations of differences in mitochondrially localized serine 727 phosphorylated STAT3 (mtSTAT3-pS727) in preadipocytes and adipocytes, here, we hypothesize and speculate further on the role of mitochondrial STAT3 in adipogenesis.

- Description: That people from around the world have incorporated numerous plant and animal products into their lives, economies, cultures, traditions and histories is well known, and is the subject of a multitude of academic and non-academic documents across many disciplines. Historically, the use of these products has underlain trade between cultures and continents and the domestication of many present day crops and breeds (Laws 2011), so much so, that most urban citizens in the developed world have forgotten the original wild origins of current day staples in foods (eg corn, potatoes, rice, tomatoes, oranges, melons, sugar, coffee, tea, spices), medicines (aspirin, codeine, quinine, strychnine), fibres (cotton, sisal, coir, hemp), resins (lacquer, gum Arabic, rubber, turpentine), dyes (cochineal, indigo, saffron), intoxicants (tobacco, mushrooms, cannabis, opium) and artefacts. While such staple foods, medicines and the like used by the ‘western’urban consumer have become domesticated and are now almost exclusively produced in farming systems or replaced by synthetic substitutes, thousands of other animal, plant and fungi species are still widely used by peoples around the world.
