Available in PDF, EPUB and Kindle. Book excerpt: Until the 1980s, global increases in food production exceeded the concomitant growth of human populations. However, progressively agriculture is becoming unable to meet the world-wide per capita needs for food. Unless there is major international cooperation in addressing the problems associated with population control, it is predicted that the global human population will reach more than 14 billion by the year 2050, with provision of adequate food, fuel and space for such an increased population unachievable. These problems are accentuated by factors such as world-wide reductions in soil fertility, the accelerating degradation of land that is suitable for food production through soil erosion, the world-wide trend for migration of human populations from rural habitats to cities and extremely rapid rates of global deforestation. Possible solutions to global sustainability in agriculture and natural resources must involve an integration of ecological, sociological, cultural, and economic considerations, as well as mandated international and national policies. This publication outlines these problems and attempts to seek solutions.

Book Synopsis Subsurface Hydrological Responses to Land Cover and Land Use Changes by : Makoto Taniguchi
Download or read book Subsurface Hydrological Responses to Land Cover and Land Use Changes written by Makoto Taniguchi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since human beings first appeared on the earth, we have changed land cover and land use for our own purposes, such as conveniences and high productivity. As a result of the land cover and land use changes, many serious environmental problems occur on the earth. Studying meteorological and hydrological effects of vegetation and land cover/use changes helps us to understand the environmental changes and problems happening near the earth surface, because the vegetation distributes the solar energy and water on the earth surface into atmosphere and geosphere. Subsurface hydrological responses to land cover and land use changes have drawn only regional environmental concerns, although global change caused by biosphere change has been studied in various scientific fields. The changes in land cover and land use alter water, solute and heat cycles in basins and elements of those balances, including evapotranspiration, groundwater recharge rate, discharge rates into rivers or ocean and soil moisture content, which are directly or indirectly related to the global environmental issues. Therefore, the changes in biosphere may substantially alter the subsurface hydrological system. For instance, increased groundwater recharge rates following clearing forest into grasses might be one consequence resulting in rising water tables and salinization.
