Miss Emma’s cows just can’t stay put! Each time they wander into Cowboy Kirby’s yard, he uses odd and even numbers to count the herd. Then he sends all the evens back to Emma and keeps the odds for himself. It’s only fair, he thinks. And, besides, Emma sure is cute. Kirby doesn’t notice that his herd keeps getting smaller while Emma’s grows larger. Emma is the kind of gal that is good at math (as well as running a ranch and baking a cake). Yet she’s tenderhearted and doesn't want to hurt her friend's feelings by explaining his math mistake. How will she solve their problem with odds and evens? Count on Emma for coming up with a surprise ending!

The arid frontier has been a challenge for humanity from time immemorial. Drylands cover more than one-third of the global land surface, distributed over Africa, Asia, Australia, America and Southern Europe. Disasters may develop as a result of complex interactions between drought, desertification and society. Therefore, proactive planning and interactive management, including disaster-coping strategies, are essential in dealing with arid-frontier development. This book presents a conceptual framework with case studies in dryland development and management. The option of a rational and ethical discourse for development that is beneficial for both the environment and society is emphasized, avoiding extreme environmentalism and human destructionism, combating both desertification and human livelihood insecurity. Such development has to be based on appropriate ethics, legislation, policy, proactive planning and interactive management. Excellent scholars address these issues, focusing on the principal interactions between people and dryland environments in terms of drought, food, land, water, renewable energy and housing. Audience: This volume will be of great value to all those interested in Dryland Development and Management: professionals and policy-makers in governmental, international and non-governmental organizations (NGOs), as well as researchers, lecturers and students in Geography, Environmental Management, Regional Studies, Development Anthropology, Hazard and Disaster Management, Agriculture and Pastoralism, Land and Water Use, African Studies, and Renewable Energy Resources.

Over the past 30 years or so, research effort in behaviour and ecology has progressed from simple documentation of the habits or habitats of differ ent species to asking more searching questions about the adaptiveness of the patterns of behaviour observed; moved from documenting simply what occurs, to trying to understand why. Increasingly, studies of behav iour or ecology explore the function of particular responses or patterns of behaviour in individuals or populations - looking for the adaptiveness that has led to the adoption of such patterns either at a proximate level (what environmental circumstances have favoured the adoption of some particular strategy or response from within the animal's repertoire at that specific time) or at an evolutionary level (speculating upon what pres sures have led to the inclusion of a particular pattern of behaviour within the repertoire in the first place). Many common principles have been established - common to a wide diversity of animal groups, yet showing some precise relationship between a given aspect of behaviour or population dynamics and some particular ecological factor. In particular, tremendous advances have been made in understanding the foraging behaviour of animals - and the 'decision rules' by which they seek and select from the various resources on offer - and patterns of social organization and behaviour: the adap tiveness of different social structures, group sizes or reproductive tactics.

Originally published in 1982, Time Resources, Society and Ecology examines and seeks to examine the time dimension in terms of the ecology, technology, social organization and spatial structure of the human habitat. Approaches to time resources – sociological time-budget studies, anthropological activity analysis, and economic analysis of money allocation – have been limited by their sectoral scope or their failure to relate effectively to the processes of social interaction, technological change and environmental structure. In this book, the book’s articulation of time resources is developed in a general theoretical framework of action and interaction in time and space. The book examines constraints and possibilities facing preindustrial societies and throws light on the impact of technology on modern societies. Basic models of time allocation are presented, and, finally, a cross-cultural comparison is made of the mobilization of time resources in preindustrial societies. Geographers, social anthropologists and human ecologists should find this work directly relevant to their interest in understanding the interactions between man and environment.
