Crop wild relatives (CWR) are plant species which are more or less closely related to crops. They are a vital resource by providing a pool of genetic variation that can be used in breeding new and better adapted varieties of crops that are resistant to stress, disease, drought and other factors. They will be increasingly important in allowing crops to adapt to the impacts of climate, thus safeguarding future agricultural production. Until recently, the main conservation strategy adopted for CWR has been ex situ - through the maintenance of samples as seed or vegetative material in various kinds of genebank or other facilities. Now the need to conserve CWR in their natural surroundings (in si...
Since its first publication in 1962, Gimson’s Pronunciation of English has been the essential reference book for anyone studying or teaching the pronunciation of English. This eighth edition has been updated to describe General British (GB) as the principal accent, rather than RP, and the accompanying transcriptions have been brought into line with recent changes in pronunciation. This latest edition also includes completely rewritten chapters on the history of the language and the emergence of a standard, alongside a justification for the change from RP to GB. A further bonus to this important text is its extensive and attractive new Companion Website (www.routledge.com/cw/cruttenden), wh...

This book offers readers a basic grounding in L2 vocabulary acquisition. In addition, it provides theoretical analyses and empirical data regarding Chinese learners of English: their specific learning difficulties, needs, strategies, etc. The book provides an overview of the research in L2 vocabulary acquisition in the last two decades. Linguistic, psycholinguistic, socio-cultural, neurolinguistic, and corpus linguistics analyses are considered. The book constructs a comprehensive framework for Computer Assisted Vocabulary Learning (CAVL). This is achieved by providing an overview of vocabulary learning in CALL and then proposing a big framework within which most vocabulary learning programs can be conceptualized. The author then gives a detailed account of how Chinese learners approach English vocabulary learning. She provides an up-to-date picture of the overall situation regarding the language policies adopted, the traditional, orthodox approach to language learning, and the recent reforms implemented in Chinese universities. General and specific vocabulary learning difficulties encountered by Chinese learners are documented and analysed and empirical studies are reported.
Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.
