Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.

What do babies and young children really need? This impassioned dialogue cuts through all the theories, platitudes, and controversies that surround parenting advice to define what every child must have in the first years of life. The authors, both famed advocates for children, lay out the seven irreducible needs of any child, in any society, and confront such thorny questions as: How much time do children need one-on-one with a parent? What is the effect of shifting caregivers, of custody arrangements? Why are we knowingly letting children fail in school? Nothing is off limits, even such an issue as whether every child needs or deserves to be a wanted child. This short, hard-hitting book, the fruit of decades of experience and caring, sounds a wake-up call for parents, teachers, judges, social workers, policy makers-anyone who cares about the welfare of children.

The Little Green Data Book 2017 is based on World Development Indicators 2017 and its online database. Defining, gathering, and disseminating international statistics is a collective effort of many people and organizations. The indicators presented in World Development Indicators are the fruit of decades of work at many levels, from the field workers who administer censuses and household surveys to the committees and working parties of the national and international statistical agencies that develop the nomenclature, classifications, and standards fundamental to the international statistical system. Nongovernmental organizations have also made important contributions. We are indebted to the World Development Indicators partners, as detailed in World Development Indicators 2017 .

This volume brings together selected papers presented and discussed at the Conference on Conservation of West and Central African Rainforests, held in Abidjan, November 5-9, 1990.
