Land use/cover change (LUCC) is often the cumulative result of individual farmer's decisions. To understand and simulate LUCC as the result of local decisions, multi-agent systems models (MAS) have become a popular technique. However, the definition of agents is not often based on real data, ignoring the inherent diversity of farmers and farm characteristics in rural landscapes. The aim of this paper is to describe an empirical method that defines an agent typology and allocates agents into the different agent types for an entire region.

Assessing factors influencing phosphorus (P) availability in soils is important in preventing its overexploitation and excessive application in agricultural systems. Despite high historical P applications in the federal state of Brandenburg (Germany), county data on soil test P (STP) reveal considerable disparities in soil available P. In addition, negative soil balances as a result of small mineral P and manure inputs have been observed, raising questions about the factors leading to this situation.

Nitrate Vulnerable Zones (NVZ) are employed as compulsory instruments to meet standards on EU water quality. Farmers operating in NVZs face a number of restrictions on agricultural activity and a greater requirement for record keeping in relation to timing and quantities of nitrogen inputs used. This paper presents results of a survey into the attitudes and values of farmers within the designated Nitrate Vulnerable Zones (NVZs) in Scotland. A typology based on perceptions towards water quality management was developed using factor and cluster analysis techniques.

South Asia is one of the most densely populated regions of the world, where despite a slow growth, agriculture remains the backbone of rural economy as it employs one half to over 90 percent of the labor force. Both extensive and intensive policy measures for agriculture development to feed the massive population of the region have resulted in land degradation and desertification, water scarcity, pollution from agrochemicals, and loss of agricultural biodiversity.

We describe the results of a survey of farmers’ perceptions of and satisfaction with the performance of watershed development activities on socioeconomic, agriculture and livestock, and environmental attributes. We administered a questionnaire to 120 farmers randomly interviewed in the Morni Hill area of the Siwalik Himalayas in India. Our results show that the farmers have considerable knowledge about the implementation of watershed development activities and their impact on the economy, agriculture and the environment.

Land-use and cover changes around Budongo Forest Reserve (BFR) were analysed from multi-temporal LandSat images (1988 and 2002) and associated field-based studies in 2003-2004. Three major land-use and cover classes: forest/woodland, sugarcane plantations and grassland/shifting-cultivation/settlements were clearly discriminated. The area under sugarcane cultivation increased over 17-fold, from 690 ha in 1988 to 12729 ha in 2002, with a concomitant loss of about 4680 ha (8·2 per cent) of forest/woodland, mainly on the southern boundary of BFR.

A major development concern of the 1970s and 1980s was 'the other energy' or 'woodfuel crisis'. Woodfuel use in developing regions of Africa, Asia, and Latin America was believed to be a key factor in tropical deforestation, and the loss of forests was projected to result in widespread woodfuel shortages. In recent years, however, it has become apparent that woodfuel production is seldom a direct cause of deforestation (although it may be a by-product), and that most woodfuel demand is met by trees and shrubs growing outside of forest areas.

The prevention of soil erosion is one of the most essential requirements for sustainable agriculture in developing countries. In recent years it is widely recognized that more site-specific approaches are needed to assess variations in erosion susceptibility in order to select the most suitable land management methods for individual hillslope sections. This study quantifies the influence of different land management methods on soil erosion by modelling soil loss for individual soil-landscape units on a hillslope in Southern Uganda.

This paper addresses the hydrological and meteorological extremes that may be deduced from the taxation records of the estates of Brtnice, Třebíč and Velké Meziříčí, all in the Moravian-Bohemian Highlands of the Czech Republic, for the years 1706–1849. At that time, damage to agricultural crops constituted grounds for tax remission for individual farmers and landowners.

A soil survey and mapping program financed by the municipality of Gazi located on the north–central part of Crete was carried out. The studied area is characterized by a moist meso-Mediterranean climate and different degrees of land degradation from human activities. Surface soil horizons are eroded, resulting in fertility decline for olive trees, the dominant crop. According to the U.S. Department of Agriculture classification, the soils at higher altitudes are classified as Entisols xerorthents and those at lower altitudes as E. xerofluvents.

The area of degraded forests in Vietnam is substantial, currently about 3.1 million ha of which about 1.7 million ha (55� %) were granted to individual farms for reforestation. However, the result of farmers’ reforestation efforts is limited. We aimed to examine the financial return, technical efficiency, and factors determining reforestation with a native tree species (Canarium album) by farms. Our results showed that reforestation with C. album is less financially profitable than that with an exotic tree species (Acacia mangium) as the alternative land use option.

Protection and management of intellectual property rights over unique crop genetic resources, biodiversity, new cultivars in crops and unique products from crops attains significance in the back drops of globalisation and trade liberalisation. Members of WTO, including India are taking earnest efforts to protect the sovereign rights over crop genetic resources and biodiversity by enacting specific Acts. A deep knowledge about these Acts and their implications is essential for achieving their specific goals.
