Røskaft   Preface  Archaeological evidence suggests that the earliest Neolithic resource users made their decisions on resource use by selecting the best areas for different uses. Resource management strategies have been influenced to varying extents by the nature of the land ever since (Mango, 1996). Conscious land use planning, now worldwide considered to be a panacea of resource use conflicts and a way of increasing productivity, originated during the Greek empire when philosophers like Socrates, Plato and Aristotle encouraged reasoning, logic, invention and scientific ways of solving problems. On the other hand, past and present efforts on land resources management seem to be inadequate as land degradation, climate change, and demographic pressure continue unabated and land productivity continues to decline at an alarming rate, which is symptomatic of our failure to mitigate the problems. We now channel more than 40% of terrestrial net primary productivity, which is sustenance of all animals and decomposers, to our own needs (Vitousek et al., 1986). Forty-five percent is under cropland and permanent pasture, 36% of Africa, 30% of North America, 35% of South America, 47% of Europe, 25% of former Soviet Union (Woodroffe et al., 2005). The current rate of land resources degradation worldwide is sending a shockwave through mankind. Statistics show that soil erosion and other factors are leading to an irreversible loss of land productivity on more than six million hectares of fertile land a year - about 24% of the inhabited land (Lal, 1993). The values of individual continents range from 12% in North America, 19% in Ocenia, 26% in Europe, 27% in Africa and 31% in Asia (Lal, 1993). Regardless of the methods used for the assessment, it is clear that it is a worldwide problem requiring attention. For example, the Sub-Saharan Africa imports about 10 million tons (60% of demand) of rice annually at a cost of around US $ 6 billion, which is the largest continent’s import bill after petroleum (Ngailo & Kaswamila, 2011). In other words, the need for natural resources conservation is as great today as it ever was. Entering the 22 nd Century, the challenges to scientists, conservationists, politicians, planners, and decision-makers are to make the world a safe place to live in, today and tomorrow, for the benefit of the present and future generations. Our children and grandchildren should not ask us: why didn’t you take action to safeguard our planet? X Preface This book is about finding the best way to manage challenges emanating from accelerating natural resource use. The contributors in this book have vast expertise and experience in natural resources management. All the chapters suggest that sustainable natural resources management can only be achieved through use of system thinking to help us think and learn collectively how to manage complexities and challenges. It provides an integrated approach which finally creates an enabling environment for stakeholders to adopt and benefit from; and adoption of resilience thinking as a paradigm for systematic natural resource management planning process that offers hope of transformational change in the management of socio-ecological systems. It is also evident that technology use such as GIS and remote sensing and modelling have great roles in natural resources management.  Abiud Kaswamila Department of Geography and Environmental Studies The University of Dodoma, Dodoma Tanzania [...]... category of natural resources This implies the definition of the appropriate set of relevant indexes for the natural resources, influenced by the water management policy As shown in the literature, five indexes are most relevant for the natural resources category in the framework of water resource management: the total water resources; the water resources per capita; the utilization rate of the water resources; ...
