Background: Conventional cattle ranching and agricultural practices have severely degraded and fragmented tropical forests in Latin America. This trend has resulted in the loss of a range of ecosystem services upon which humans depend, especially those that support agricultural production, such as biodiversity, the provision of water and soil fertility. Consequently, conventional cattle ranchin...
Recent developments in aerospace survey technology, modelling of crop production processes, and geographic information systems have created promising opportunities for agricultural resource management. One of the potential fields of application is in the agricultural risk management, in particular in assessing the impacts of natural hazards on agricultural productions. This seems to be the bott...
Typical WSN(Wireless Sensor Network) applications in precision agriculture include production process management, plant growth optimization, farmland monitoring and so on. Middleware, which can connect hardware, applications, and enterprise systems, is required to construct ubiquitous agricultural environment combining WSN technology with different agricultural applications, but there have been...
Human fertility can affect agricultural production through its effect on supply of agricultural labor. Using the fact that in traditional, patriarchal societies, sons are generally preferred to daughters, we isolate exogenous variation in the number of children born to a mother and relate it to the agricultural labor supply and production in Uganda, which has a dominant agricultural sector and ...
This paper describes the scale and nature of agricultural production in urban, suburban and peri-urban zones of Mexico City and how these have adapted to the changing demands from urban populations for food, wood and recreation. It also demonstrates how agricultural producers have successfully adapted their products and their production methods, including building on traditional production syst...
The spectrum of risks that affect the income of agricultural producers and agribusinesses is quite broad. The two predominant risks are: price risk, reflecting variations in market prices for agricultural commodities and production inputs; and production risk, which encompasses variations in the volume or quality of the commodity produced. This note focuses on one of the most pervasive producti...
Arid and semi-arid lands constitute a large proportion of available agricultural and rangeland in the world. These lands are characterised by low and unreliable rainfall, low land productivity, and low socioeconomic status of the inhabitants. Livestock plays a very significant role in their economies. Leguminous trees and shrubs, which dominate the natural rangelands, are often higher in crude ...
Agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. Due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. Currently, environmental laws and regulations pertaining to ...
A dramatic increase in agricultural production can be observed during the past decades in Brazil, mostly due to increases in yield. Furthermore the sugarcane production increased based on area expansion, mainly over pasture areas. In the same period Brazil became a leading global beef producer. Brazilian official agricultural statistics time series data on agricultural production from 1980 unti...
