Land degradation

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. This is considered to be an important topic of the 21st century due to the implications land degradation has upon agricultural productivity , the environment, and its effects on food security. According to the Special Report on Climate Change and Land of the Intergovernmental Panel on Climate Change : "About a quarter of the Earth's ice-free land area is subject to human-induced degradation medium confidence. Soil erosion from agricultural fields is estimated to be currently 10 to 20 times no tillage to more than times conventional tillage higher than the soil formation rate medium confidence. The United Nations Sustainable Development Goal 15 has a target to restore degraded land and soil and achieve a land degradation-neutral world by

Economics of land degradation and improvement

Land degradation is globally pervasive and, in some places, irreversible. Humans have historically modified the environment directly and indirectly to meet their requirements, but the rate and extent of degradation has accelerated dramatically in recent years. The resulting anthropogenic impacts on land have been so profound that a new geologic era has been recognized, the Anthropocene - generally dated from Many studies have contributed to the current theoretical understanding of land degradation. However, some critical aspects that underlie existing knowledge remain to be addressed. Even in the context of extensive study, surprisingly, there remain serious gaps is in the basic foundation of understanding. Clearly, a foundation should contribute to the extensive existing progress to build a coherent whole, rather than proposing yet another conceptual framework.

It seems that you're in Germany. We have a dedicated site for Germany. This book offers an overview of recent literature on land degradation and its interrelationship with socio-economic development processes in the developing world. It provides an in-depth analysis of land degradation as a physical process, with an emphasis on the local and regional scales. The volume contains a detailed case-study of ravine formation processes in the Chambal valley, a unique but least studied part of the world.

Land Degradation and Socio-Economic Development

Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain—fed cropland, irrigated cropland, or range, pasture, forest or woodlands resulting from natural processes, land uses or other human activities and habitation patterns such as land contamination, soil erosion and the destruction of the vegetation cover UNCCD, Thirty-three per cent of global land area is degraded FAO, About 47 per cent of degrading land globally is forest; cropland accounts for approximately 18 per cent of the global total degraded land Bai et al. About two billion people and 1. The alarming rates of degradation globally have been recognized and accorded international efforts to help halt and reverse land degradation and combat desertification ibid.

Achieving goals in land and soil protection, for example, cannot build on a long tradition of policymaking or on a solid basis of information and data for monitoring.

Ничего себе капелька. В голове у нее стучало. Повернувшись, она увидела, как за стеной, в шифровалке, Чатрукьян что-то говорит Хейлу. Понятно, домой он так и не ушел и теперь в панике пытается что-то внушить Хейлу. Она понимала, что это больше не имеет значения: Хейл и без того знал все, что можно было знать. Мне нужно доложить об этом Стратмору, - подумала она, - и как можно скорее. ГЛАВА 38 Хейл остановился в центре комнаты и пристально посмотрел на Сьюзан.

Он опустил шторку иллюминатора и попытался вздремнуть. Но мысли о Сьюзан не выходили из головы. ГЛАВА 3 Вольво Сьюзан замер в тени высоченного четырехметрового забора с протянутой поверху колючей проволокой.

 Дэвид, - вздохнула она, заметив на тумбочке его записку.  - Скажи мне, что такое без воска. Ты же знаешь, что шифры, которые не поддаются, не выходят у меня из головы.

Она поправила прическу. - Ты же всегда стремился к большей ответственности. Вот. Он печально на нее посмотрел.

Land degradation is a global problem that particularly impacts the poor rural inhabitants of low and middle-income countries.
