The ability to incorporate and manage the different drivers of land-use change in a modeling process is one of the key challenges because they are complex and are both quantitative and qualitative in nature. This paper uses Bayesian belief networks (BBN) to incorporate characteristics of land managers in the modeling process and to enhance our understanding of land-use change based on the limit...

Biomass burning is an essential part of slash-and-burn (S&B) agriculture, which is widely practiced as an important food production system in the tropical mountains of Southeast Asia. S&B agriculture used to be sustainable and carbon neutral; CO2 emissions by biomass burning were balanced with photosynthetic biomass growth, and land use was stable. However, due to drastic land-use change in the...

erosion and sediment movement phenomena are one of the most complex issues in management of rivers drainage areas that in water projects are very important. that its measurement wants high time and cost. issue of surface runoff in river basin is a complex issue that human knowledge and understanding about its physical laws a viewpoint of some mathematical formulas is limited. in this study to i...

introduction soil infiltration rate is the major soil hydraulic property which can be affected by the soil physical characteristics and management practices. the use of land can affect various soil properties such as physical and hydraulic properties. differences of the hydraulic soil characteristics such as infiltration rate in various land uses can affect their potential to runoff production ...

It is widely recognized that forest and water resources are intricately linked. Globally, changes in forest cover to accommodate agriculture and urban development introduce additional challenges for water management. The U.S. Southeast typifies this global trend as predictions of land-use change and population growth suggest increased pressure on water resources in coming years. Close attention...

Urban agriculture offers an alternative land use for integrating multiple functions in densely populated areas. While urban agriculture has historically been an important element of cities in many developing countries, recent concerns about economic and food security have resulted in a growing movement to produce food in cities of developed countries including the United States. In these region...

As a source of livelihood, agriculture (including forestry and fishing) remains the largest sector of Indian Economy. While its output share fell from 28.3% in 1993-94 to 14.4% in 201112, employment share declined from 64.8% to 48.9% over the same period. Therefore, almost half of the workforce in India still remains dependent on agriculture. Given the low share of this workforce in the GDP, on...
