Wireless sensor networks are useful complements to monitoring systems in greenhouse agriculture. Based on the requirements of this system, we design and implement one chine-type wireless sensor network (C-WSN) to monitor crops’ growing environment. In the hardware, CC2420RF are applied in sensor nodes as the wireless transceiver, and the MCU, MSP430F149, is used in sensor nodes and sink nodes, ...

It is difficult to quantify or treat the photographic data mathematically. Digital image processing and image analysis technology based on the advances in microelectronics and computers circumvent these problems associated with traditional photogra...

Sub Saharan African agriculture is currently facing challenges in international trade with respect to external market access conditions and competition in world markets as a result of trade liberalization efforts under the world trade organization (WTO) agreements and in particular the agreement on agriculture (AoA). This paper presents the performance of agricultural exports for selected count...

Fallow management is a common practice of traditional shifting cultivation in Southeast Asia and it survives throughout the region for many centuries (Spencer 1966). The systems are often found among the ethnic minorities in the region but governments, on the other hand, see the system as a primitive form of agricultural production, destruction to the forests and watersheds, wasteful and unprod...

Marketing of innovation is highly complex because the potential customers usually are unaware of the new product. In the same way, the markets as known in traditional marketing are frequently absent. The biotechnology is based on a crosssectional knowledge, which represents a particular challenge and is different from other more mature and more traditional market products. Customers and biotech...

Mark Elvin treats the problem of economic stagnation in the traditional Chinese rural economy as resulting from obstacles to technological innovation. In application to agriculture, Elvin's formulation may be put in these terms: why did the Chinese economy not succeed in introducing technological innovations into the process of cultivation, thereby increasing the productivity of agriculture? El...

Businesses and professions must stay in accord with social ethics, or risk losing their autonomy.A major social ethical issue that has emerged in the past four decades is the treatment of animals in various areas of human use. Society's moral concern has outgrown the traditional ethic of animal cruelty that began in biblical times and is encoded in the laws of all civilized societies. There are...
