UNDERSTANDING THE DYNAMICS OF LAND USE CHANGES: ASSESSMENT OF SUSTAINABLE LAND MANAGEMENT PROJECT SITES IN BHUTAN

Understanding of spatial distribution of available soil nutrients is important for sustainable land management. An attempt has been made to assess the spatial distribution of available soil nutrients under different soil orders and land uses of RiBhoi, Meghalaya, India using geo-statistical techniques. Seven Land Use Land Cover (LULC) classes were selected from LULC map on 1:50,000 scale prepared by National Remote Sensing Centre (NRSC) viz. Abandoned Jhum (AJ), Current Jhum (CJ), Deciduous Forest (DF), Double Crop (DC), Evergreen Forest (EF), Kharif Crop (KC) and Wastelands (WL). Again, three soil orders were identified by National Bureau of Soil Survey and Land Use Planning (NBSS&LUP) in RiBhoi district of Meghalaya, India viz. Alfisols, Inceptisols and Ultisols. 105 soil samples were collected, 5 replicated soil samples from 21 strata derived from 7 LULC and 3 soil orders. Soil samples were analyzed for available nitrogen (N), available phosphorus (P2O5), available potassium (K2O) and available zinc (Zn) using standard procedures. One way ANOVA was carried out using IBM SPSS Statistics 20.0 software. Significance levels were tested at p≤0.05. N content varied from low (215.50 kg/ha) to medium (414.30 kg/ha) with mean value of 291.50 kg/ha. On the other hand, P2O5 content varied from low (19.90 kg/ha) to high (68.30 kg/ha) with mean value of 43.52 kg/ha. Similarly, K2O content varied from low (112.09 kg/ha) to high (567.84 kg/ha) with mean value of 273.68 kg/ha. Again, Zn also varied from low (0.26 ppm) to high (1.46 ppm) with mean value of 0.64 ppm. In Alfisols, N was found to be higher in EF, AJ & CJ than DF, DC, KC and WL. KC has been found to have lower N than all other LULC classes. Higher P2O5 has been found under EF over KC and WL. AJ has been found to have higher K2O than all other LULC classes. K2O has also been found to be higher in CJ over DC, KC and WL. DF and EF have been found to have higher K2O than KC and WL. Zn has been found to be higher in EF over CJ, DC and WL. In Inceptisols, higher amount of N was observed under EF over all other LULC classes. Higher N has also been found under CJ over DF, DC, KC and WL. P2O5 content was found to be higher under DF over all other LULC classes. Higher P2O5 content was also found under AJ, CJ and DC than KC and WL. Higher amount of K2O has been found under AJ over all other LULC. K2O content of soil under DF was also higher than CJ, EF, KC and WL. Zn has been found to be higher under EF over all other LULC classes. Zn content under CJ has also been found to be higher than AJ, DF, KC and WL. In Ultsols, higher amount of N has been found under EF compared to all other LULC classes. Lowest N content was found under KC. P2O5 content was found to be higher under EF, DF and AJ over all other LULC. K2O content has been found to be higher under CJ in comparison to all other LULC classes. K2O content of EF and DF were also found to be higher than AJ, DC, KC and WL. Again, K2O content has been found to be higher under DC compared to AJ, KC and WL. Zn content under EF and AJ was found to be higher than all other LULC classes. CJ, DF, DC, KC and WL have been found to have lower Zn content. It has been observed that P2O5 content is significantly higher in inceptisols irrespective of LULC classes. The study has highlighted the spatial distribution of available soil nutrients as a function of soil orders and LULC. This will be a useful input in sustainable land management programmes.

Definition Of

The normative legal acts, scientific publications and land management projects on the organization of the territory in particular of the state scientific institutions and enterprises of the National Academy of Agrarian Sciences of Ukraine (hereinafter - NAAS) are analyzed. It is established that in the current legislation there is no type of land management documentation to address the organization of land use of state institutions and enterprises of NAAS. Emphasis is placed on the need to develop an industry standard that will take into account the specifics of land use of NAAS institutions and enterprises, which include land, research fields, nurseries, valuable land for research, which must be taken into account when developing land management documentation. The definition of the term organization of the territory is offered. The design of regulatory documents (industry standard) in accordance with DSTU 1.5: 2015, which indicates the typical structural elements that need to be shown when developing the standard. The branch standard of the land management project concerning the organization of the territory of land use of the state establishments and the enterprises of NAAS is offered taking into account specific functional features of use of the agricultural lands of the state establishments and the enterprises of NAAS.

And Control

Chilean needle grass (Nassella neesiana) is a containment pest in the Regional Pest Management Strategy for Marlborough It is of concern because it has sharptipped seeds that bore into the eyes and pelts of livestock Discovered in Marlborough in the 1930s it now infests 4311 ha In 1987 18 properties were infested increasing to 53 by 2000 and 96 by December 2005 In addition both the range and density of Chilean needle grass has increased significantly since 1987 and to date no infestations have been eradicated Failure to stop this spread is due to the difficulty of both identification and control Effective control and land management methods for this weed are urgently needed The probability of this weed spreading further both within and beyond Marlborough appears to be high This conclusion along with land use changes has implications for the review of the Regional Pest Management Plan

The authors examined the key components of In moden post – reform conditions when the organization of the use of agricultural land is carried out without land management project documentation and relevant recommendations, in conditions of significant pressure from industrial and urban development, this is primarily the main reason for the decline in soil fertility and the development of degradation processes, a departure from the classical sustainable agricultural land use, formed on the principles of land management and the laws of nature management [1- 4]. In the process of functioning, once-stable land uses have not changed borders for decades, which indicates a rational overall size of agricultural land use, when all three production factors: “labor”, “land” and “capital” are in full compliance with each of them, that is, harmonization, rationalization and greening [5, 6]. This harmonization eliminates the presence of such disadvantages as: far-earth, cross-stripe, wedging, etc., creates conditions for the rationai organization of the use of agricultural land [2, 5, 6].

The North Otago area has a climate that often fluctuates from severe drought to flood in a short space of time. The climatic extremes, and some unsustainable land use practices can put the area's fragile loessial soils at risk of water and wind erosion. This paper outlines an approach used in North Otago which has enabled the community to identify its sustainability and environmental issues and begin to make changes to land use and farmer attitudes. A group of key farmers was brought together to oversee the preparation of Sustainable Land Management Guidelines for the downlands. (This group became the North Otago Sustainable Land Management Group - NOSLaM Group.) From this grew a wide-ranging community-driven project with a full-time co-ordinator, and a vision to have most land users adopting sustainable farming systems. This should ensure the area is ready to meet the world market demands for environmental quality in food and fibre production. The Group will promote individual environmental farm plans which will have a monitoring component. Some farmers will work towards some form of property accreditation such as ISO 14001. This pilot project will be highlighting the economic benefits of environmentally sound farming methods, through seminars, field-days, newsletters and a demonstration farm. The Group is working in partnership with farmers, the processing industry and marketing people to identify market opportunities for the area's food and fibre produced by environmentally friendly farming systems.
