Book Description
Sixty years ago at the Waite Agricultural Research Institute, G. Samuel, a plant pathologist, and C. S. Piper, a chemist, published their conclusion that the cause of roadside take-all, a disease of oats, was manganese deficiency. This report, together with the concurrent and independent studies of W. M. Carne in Western Australia were the first records of manganese deficiency in Australia and came only six years after McHargue's paper which is generally accepted as the final proof of the essentiality of this element. There must have been a few doubts for some people at the time, however, as the CAB publication, 'The Minor Elements of the Soil' (1940) expressed the view that further evidence to this effect was provided by Samuel and Piper. Their historic contributions are recognised by the International Symposium on Manganese in Soils and Plants as it meets on the site of their early labours to celebrate the 60th anniversary. This year Australians also acknowledge 200 years of European settlement in this country and so the Symposium is both a Bicentennial and a diamond jubilee event which recognises the impact of trace elements on agricultural development in Australia. In a broader sense, a symposium such as this celebrates, as it reviews, the efforts of all who over the ages have contributed to our knowledge of manganese in soils and plants.

Book Description
This monograph examines contemporary environmental challenges facing Nepal, this landlocked country’s representativeness in the wider South Asian context is both distinct and generalizable. In large part, this is because of its extremes of physiographical structure- plains, hill ranges, mountainous massifs - and wide range of altitudinal terrains, which represent and replicate South Asian and East Asian continental conditions differing as markedly as humid tropical lowlands, sub-tropical hill ranges and temperate to sub-arctic mountainous environments. Associated forest regimes, in which deforestation and reforestation patterns have evolved in recent times, and differing densities of settlement and cleared agricultural landscapes in each of these altitudinal zones, add to the environmental diversity of Nepal. Associated fauna and exotic species are in various states of endangerment especially Bengal tigers, one horned rhinos, wild elephants, crocodile, musk deer, and peasants, to name a few- so that their forested and mountainous habitats as ‘Wild Life Reserves’ also deserve our attention, and are featured in this monograph’s remit.

Book Description
One of the highest priorities for human societies in the 21st century, under the challenges of predicted great environmental changes, is to conserve all kinds of biodiversity across the planet. Among all the biota that exist on Earth, forest ecosystems demonstrate a high degree of biodiversity, being thought to comprise the most diverse ecosystems, as most of the terrestrial species in the world dwell in these ecosystems. Forest biodiversity is interlinked to a web of socio-economic factors, providing an array of goods and services that range from timber and non-timber forest resources to mitigating climate change and conservation of genetic resources; therefore, it is innately linked to ecosystems and human well-being. However, in recent decades, the decrease in forest biodiversity has been a crucial and ongoing environmental issue that needs special attention and adapted ecosystem management. This Special Issue book on forest biodiversity (FB) includes a selected number of research works from all over the world dealing with emerging issues, for understanding FB and its needs for conservation, ecological processes, disturbances, climate change and ecosystems resilience, structural complexity and ecosystem functions, ecological theories and silvicultural practices, and ecosystems stability. More specifically, it includes papers focused on the indicators and methods for assessing and monitoring forest biodiversity, evaluation of practices, planting and silvicultural treatments, and management and monitoring methods, with an overall goal to provide new insights on forest biodiversity conservation, conservation of forest biodiversity in protected areas, treatments of endangered or threatened forest habitats, and sustainable management of forest resources.

Book Description
Abstract: Developing countries start the decade facing two major challenges: to continue the social and economic progress of the past 30 years in an international climate that looks less helpful; and to tackle the plight of the 800 million people living in absolute poverty, who have benefitted too little from past progress. This report examines some of the difficulties and prospects in both areas. One of its central themes is the importance of people in development. The first part of the report addresses the expected sluggish world economic growth as oil-importing countries reduce their current account deficits and adapt to higher energy costs. Domestic policies of developing countries will be crucial, and the fate of poor people in these countries will be decided largely by domestic opportunities and policies. The second part of the report describes the role of human development programs (in education, health, nutrition, and fertility reduction) and their related effects on productivity and population growth.
