  • Drawing on the collective expertise of world authorities, Ecological Basis of Agroforestry employs extensive use of tables and figures to demonstrate how ecologically sustainable agroecosystems can meet the challenges of enhancing crop productivity, soil fertility, and environmental sustainability. Divided into four sections, this comprehensive volume begins with a study of tree-crop interaction in tropical and temperate climates.

  • The third and fourth sections of the book include, respectively, studies for which the analysis is a modification of a traditional fluid mechanical approach and studies for which the approach is non-traditional. The division is admittedly subjective in that some of the traditional approaches have decidedly non-traditional elements.

  • Farmers have a reputation for being innovators and experimenters, willing to adopt new practices when they perceive some benefit will be gained. Over the past 40 to 50 years, innovation in agriculture has been driven mainly by an emphasis on high yields and farm profit, resulting in remarkable returns but also an array of negative environmental side effects.

  • Water is an important natural resource which forms the core of the ecological system. Human use of water depends on ambient water quality and human alterations of the landuse have an extensive influence on water quality. Water is typically referred to as polluted when its quality is adversely affected by contaminants and undergoes a marked shift in its capability to support the biological communities. The book is written for research scholars, hydrologists and environmentalists and especially students....

  • Sewage sludge as an uncalled for product of wastewater treatment poses the challenge to society of disposing of it, but at the same time gives us the opportunity of beneficial use by closing the cycle of nutrients: sludge derived from agricultural activity must return to soil if a sustainable and ecologically sound management of these materials is desirable (SEQUI et al. 2000). At present the major ways of disposing of sewage sludges are deposition, landfill and incineration, only part of the sludges are used in agriculture. ...

  • Large lakes are important because of their size and ecological distinctiveness, as well as their economic and cultural value. Optimal management of them requires a proper understanding of anthropogenic impacts, both on the lake ecosystems, as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles, and food-web structure, are all directly related to their size.

  • Forests ecosystems provide a multiplicity of goods and services of crucial ecological, social and economic importance for the sustainability of our society. Forest goods and services represent the benefits that human populations derive, directly or indirectly, from forest ecosystems functions (MEA 2005) and are therefore an inherently anthropogenic concept, since it is the presence of human beings as valuing agents that enables the translation of the basic ecological structures and processes of forests into value-laden entities. ...

  • The mountainous area occupies three fourth of the total area of Binh Dinh Province. The potential of landuse is very large. However, under the influence of irrational exploitation and natural disasters in the past, the land resource has declined, thus leading to the decline of forest resource. Furthermore, the increase of unused land and bare hills along with the decrease in the cultivated area seriously influenced on the ecological environment as well as the socio-economic development.

  • This book owes its inception to my fascination with the natural microcosms that are water-filled tree holes and, subsequently, the broader class of plant container habitats we call phytotelmata. That fascination was born, first, in a Somerset woodland, when my fellow undergraduate Alastair Sommerville pointed out to me a massive stump hole, commenting that such places were both entomologically special and of great potential as objects of ecological study.

  • Energy harvesting from ambient waste energy for the purpose of running low-powered electronics has emerged during the last decade as an enabling technology for wireless applications. The goal of this technology is to provide remote sources of electric power and/or to recharge storage devices, such as batteries and capacitors. The concept has ecological ramifications in reducing the chemical waste produced by replacing batteries and potential monetary gains by reducing maintenance costs.

  • Plant and animal species have been co-evolving synergically ever since they began to occupy the different environments found around the world. These two types of organisms have developed relationships of mutual dependence at a number of different levels, in particular those related to feeding behavior. The study of herbivore interactions has been especially relevant to the scientific community.

  • Green Infrastructure Neighbourhood Ecosystem Services (GINES) is derived from Tables [D] and [E]. It is an over-arching indicator which assumes a direct relationship between ecosystem health and the availability of regulating and cultural ecosystem services. Its calculation takes into account the fact that landscape artificial intensity reduces the supply of green infrastructure services and, at the same time, increases the number of potential beneficiaries (because of neighbourhood or easier access by transport infrastructures).

  • The Earth’s polar regions (see Figure 1.1) are ecologically, economically, and, increasingly, geopolitically important; they are particularly vulnerable to the speed and magnitude of climate change and have significant potential to influence the global climate system (Oreskes, 2004; IPCC, 2007a; Anderegg et al., 2010). Climate models and observational data have shown that polar regions have warmed at substantially higher rates than the global mean (IPCC, 2007c).

  • These interactions are discussed further in section I.B below. Factors such as rapid population growth, inequitable access to productive assets, especially land, the neglect of agriculture outside high potential areas, and the impact of external shocks, combine in certain areas to produce and reproduce poverty. Limited alternative non-farm income opportunities reinforce this situation. Poor households tend to respond either by migrating or by other options such as an expansion of farming activity to open new lands to cultivation, which may increase the pressure on natural resources.
