The Virtual Land Strategy and Management Innovation of the Sustainable Utilization of Regional Land Resource
Zhenli Luo
International Journal of Business and Management , 2009,
Abstract: The sustainable utilization of land resource is the key for the growth of economy and the social development in a regional eco-economic system. In this paper, the author introduces the “virtual land” and the “virtual land strategy” concepts, suggesting a method to calculate the consumption of virtual land, analyzing the characteristics of regional land resource in different management stages from the virtual land strategy angle. In order to deal with the problems emerged in the utilization of land resource, the author proposes relevant countermeasures.

Abstract: The study aimed at building model of dry land management. Dynamic System Analysis was used to build model and Powersim 2.51 version for simulating. The parameter used in model were fertilizer (urea, SP-36, ACL), productivity (corn, cassava, mungbean), soil nutrient (N, P, K), crop nutrient requirements (corn, cassava, mungbean, mucuna), price (corn, cassava, mungbeans corn flour, feed, urea, SP-36, KCl), food security credit, area planted of (maize, cassava, mungbean), area harvested of (maize, cassava, mungbean), (corn, cassava, mungbean) production, wages and farmer income. Sustainable indicator for ecology aspect was soil fertility level, economic aspects were productivity and farmer income, and social aspects were job possibility and traditions. The simulation result indicated that sustainable dry land management can improve soil fertility and increase farmer revenue, became sustainable farming system and farmer society. On the other hand, conventional dry land management decreased soil fertility and yield, caused farmer earnings to decrease and a farm activity could not be continued. Fertilizer distribution did not fulfill farmer requirement, which caused fertilizer scarcity. Food security credit increased fertilizer application. Corn was processed to corn flour or feed to give value added.

Abstract: This study investigates the impact of land certification on sustainable land resource management, long-term investments, and farmers’ perception and confidence on land ownership and land use rights in the dryland areas of Eastern Amhara Region, Ethiopia. Fifteen kebeles from three woredas and 20 households per kebele were selected using stratified random sampling techniques with whom face-to-face interviews were carried out. Analysis of the qualitative and quantitative data showed that, 160 households have on average 0.40 ha of farmland on steep slope area; and about 21.0% and 15% of households have fear land redistribution and the government may take their farm plot at any time, respectively. However, respondents believe that land certification reduced landlessness of women, disable and poor of poor where as it increased youths’ landlessness. The participation of households in land management practices (LMP) has shown a 15.4% increment after land certification. Nonetheless, the mean comparison of major crop yields per household is insignificant except sorghum which decreased significantly at level of p<0.1 level. Generally, land certification improves tenure security; LMP and land use rights of women and marginal groups of societies but did not crop productivity.

Abstract: Intensive farming system development will lead to trade-off between economic benefits in the short run and environmental problems, especially critical soil erosion in the long run. The excessive erosion has reduced soil quality, then caused rapid reduction in land productivity or even made the land unsuitable for agriculture. If agriculture is to become sustainable, land management must be considered as one of best management practices in farming system development. A research in Tembok Village, Buleleng Regency, Bali aims to assess land suitability, soil fertility, soil erosion and conservation, and soil nutrient management for irrigated mixed farming system in north coastal plain of Bali. It is found that coastal area in the study area is classified into poor fertile soil due to the low level of cation exchangeable capacity and organic matter content. It is potentially categorized as marginal suitable (S3) for maize, cassava, groundnuts, sweet potato, melon, chili, banana, cashew, coconut, and palmyra palm; and suitable enough (S2) for mango, papaya and fodder grasses. The erosion level was very light by 2.036 t/ha/yr. This level has good relation with the erosion level by 2.04 t/ha/yr from laboratory experiment result by Sukartaatmadja et al. (2003) with similar characteristic of land and cow manure dosage requirement by 5 t/ha/yr. To improve soil fertility and to keep soil erosion not more than 2.036 t/ha/yr, the minimum 5 t/ha/yr of manure should be added into soil.

Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.61006
Abstract:

In this paper, the problems of rational use, protection and management of water and irrigated land resources of Uzbekistan are discussed. Uzbekistan is using more than 50% water resources of the region and therefore it’s more vulnerable to the problems of water deficiency and pollution caused by mismanagement, use of outdated technologies, and climate change impact. Utilization of water resources on main branches of economy (irrigation, industry and drinking water supply) from 2000-2009 and in some cases beyond this period was analyzed. Based on the data analyzed, the conditions of irrigated land degradation in Uzbekistan are estimated. The results of this analysis suggest several possibilities toward a sustainable use of irrigated lands: i) reduction of the groundwater table depth; ii) decrease of the level of mineralization of groundwater, and iii) improvement of ameliorative conditions of irrigated lands. The causes resulting in degradation of the irrigated lands and practical measures on the reduction of salinization of the irrigated lands are also recommended.

SUSTAINABLE MANAGEMENT OF LAND DEGRADATION: THE EXAMPLE OF SECONDARY, DRYLAND SALINITY IN SOUTHWESTERN AUSTRALIA
Arthur Conacher
Revista Sociedade & Natureza , 2005,
Abstract: Worldwide, population growth is placing growing pressures on the land. Traditional, mostly sustainable farming systems developed in conjunction or integrated with native vegetation, are being or have been replaced by commercialised agriculture. Modern agriculture is often large-scale, mechanised, and reliant on agricultural chemicals and hybrid crops grown in monocultural systems. Land degradation — which has been defined as ‘alterations to all aspects of the biophysical environment by human actions to the detriment of vegetation, soils, landforms, water, ecosystems and human well-being’ (Conacher and Conacher, 2001, 364) — is one outcome. It has been described as Australia’s number one environmental problem (Diamond, 2004).The International Geographical Union’s (IGU) Study Group on Erosion and Desertification in Regions of Mediterranean-type Climate initially focussed on land degradation processes, with a strong geomorphic emphasis (reflecting the background of most of the Study Group’s members). However, it soon became apparent that research into land degradation needs to be more broadly based. This realisation is reflected in the chapter headings of Parts II and III of the main publication which arose from the work of the Study Group (Conacher and Sala, 1998). Part II’s chapters identified the main problems of land degradation in the Mediterranean world, their historical origins, the causes of the problems and some of the broader ecological, social and implications. Part III then considered a rangeof solutions to the problems, including farming practices and, more broadly, economic, social, agency and policy changes required to enable such changes to be made.

Abstract: Present land use planning level in Slovakia is resulting from the gradual knowledge evolution from soil survey and land evaluation to the sustainable land resources exploitation modelling. Particular attention is concentrated to the quantification of sustainable land use system parameters in different pedo-ecological conditions. The fundamental basis for the solution of these questions is detailed database not only about soils and land components properties, but about both, real and potential crop yields on representative set of fields, including basic economic soil management data as well. The specific aims of land use efficiency modelling are expressed in the synthesis of both the ecological and economic assessment of soil and land productivity potential. Sustainable land use and farming system models with the economic efficiency calculations are the final results. The set of presented models and maps including economic efficiency calculation enables to apply new concepts of sustainable land use in wider rate as well in agrarian landscape managing.

Journal of Applied Sciences , 2007,
Abstract: Support to farmer nurseries is classified as either hard referring to material inputs (tree seed, water, tools and fencing) or soft (information, training and backstopping advice). Against a background of poor services for smallholder farmers in the Lake Victoria basin, it was hypothesized that a number of support agents operating at the grassroot level together with farmers themselves provide the different support functions needed in the establishment of farmer tree nurseries. Through financial support from Inter-University Council of East Africa coordinated VicReS Project, a collaborative project involving Kenyatta University (Kenya), Kenya Agricultural Research Institute (KARI) and Mulingano Agricultural Research Institute (Tanzania) has been able to initiate reforestation/afforestation activities in Lake Victoria catchments ecosystems of western Kenya and western Tanzania. Through the initial activities, a total of twenty four farmer groups have been identified in western Kenya and supported through capacity building and supply of basic inputs for tree nursery seed bed preparation and management. The groups have been able to set up tree nurseries and are now managing seed beds with a total of 450,000 agro-forestry seedlings, mainly Grevillea robusta and Casuarina spp. The farmers intend to distribute the seedling among the members for planting on farm boundaries, around homesteads and woodlots within their homesteads and sell the surplus. Preliminary findings show that there is an urgent need to facilitate grassroot level support systems with larger participation from the national extension service for provision of training and backstopping advice. Strengthening the human capital of farmers and service providers emerges as critical in increasing impact. Farmer nurseries are shown to play a number of important and interrelated functions in building natural, human and social capital. Monitoring and evaluating farmer nurseries in catalyzing these three functions should therefore receive proper attention in assessing impact of sustainable land use systems. Policies need to be well articulated to address some of the major constrains identified in the Lake Victoria catchments ecosystem.

Abstract: It is necessary to evaluate sustainable land use control at county scale in China. The scientific control system of sustainable land use is deeply studied from three aspects: land use zoning, sustainable land use assessment and sustainable land use monitor. Restricting irrational land use and avoiding the negative effect of land use are social targets of the system of land use zoning. The beforehand regulating way is the available public measure land management. The system of sustainable land use assessment is to evaluate sustainable land use at county scale. In a feedback way, irrational land use will be avoided. Sustainable land use indicators at the county scale are built up based on the character of sustainable land use indicators and the trait of land resources in a county. The system of sustainable land use monitoring is timely to monitor land use/land cover changes and environmental changes. In a timely way, irrational land use will be avoided. The controlling object of regulation system of sustainable land use is land use system at county scale, and the final aim of this system is to ensure sustainable land use at county scale. Some valuable and useful information can be got for the rational land use through this system. And based on the system, some sustainable land use policies are also offered.

Abstract: We reviewed the principles and key literature related to forest tenure and sustainable forest management, and then examined the status of sustainable forestry and land ownership at the aggregate national level for major forested countries. The institutional design principles suggested by Ostrom are well accepted for applications to public, communal, and private lands. The analyses of countries as a whole suggest that problems of forest land loss and sustainable forest management are related to the amount of public lands owned, as well as the difference between developed and developing countries. Developed countries have largely achieved a stable level of land use and resource extraction after centuries of exploitation of forests and natural resources. Many developed countries do have greater amounts of private forest land than developing countries, which have occurred as the countries transfer lands to private owners in the course of development. Public lands and management approaches require diligence, but can be developed to meet the design criteria suggested by tenure rights theorists. Private or communal ownership is often considered superior, but also must meet the criteria suggested above in order to foster sustainable forest management in poor countries.
