Use of GIS in soil fertility mapping of Rapti Municipality, Chitwan, Nepal

Mapping the spatial distribution of soil fertility in a particular area gives an idea about the nutrient content in the soil which plays an im-portant role in fertilizer recommendation, sustainable soil manage-ment, integrated plant nutrient management, landuse planning, and site-specific nutrient management (SSNM). A study was carried out to assess the soil fertility status of the Rapti Municipality, Chitwan, Ne-pal. A total of 120 soil samples was collected based on land use, slope, and aspects with the useof Google Earth Pro (GEP) and ArcGIS. Based on the soil test report spatial variation of soil texture, soil pH, total nitrogen, available phosphorous, and potassium of the study area was prepared. The majority of the study area (57.11%) has sandy clay soils. The soil pH was very strongly acidic to slightly alkaline with pH values ranging from 4.8 to 8.0. Soil organic matter (1.94-3.75%), total nitrogen (0.097-0.187%), available phosphorous(51.03-270.10 kgha-1), and available potassium (169.87-358.68 kgha-1) in the soil are within the range of medium to high in the study area. To maintain this nutrient status, the use of organic manure, reduced use of chemical fertilizers, and different soil management practices should be adopted in this area.

Stakeholders' perspectives of public participation in landuse policy: the Nigeria experience

PurposeIt has long been recognised that the top-down approach is prevailing over bottom-up approach in landuse planning in African countries. The purpose of this paper is to evaluate and identify the facilitators and limitations to have effective public participation (PP), and suggest how the practices can be improved in Nigeria.Design/methodology/approachUsing Nigeria as a case study, this paper involves interviews of various stakeholders, including government staff, representatives of interest groups, general public, members of the planning board and planning commission. Information is analysed by narrative techniques of reporting.FindingsThere is a general judgment that PP is vital to landuse policy. Early public consultation was preferred, as many respondents pointed out that this would help shape the final policy. Yet, their opinion varied on whether relevant information was provided to the public, as well as their level of satisfaction with the whole process. While the process was fairly seen as giving opportunities for the public to make comments on public policy, the approach appeared not to be fruitful in many cases: (a) when the scope was broad; (b) lack of representativeness and abstruse information; (c) insufficient feedback to the participants; and (d) corruption and shortage of resources to complete the process promptly.Practical implicationsUnderstanding the facilitators and limitations that impact the success of PP can help provide guidance to improve the decision-making processes of public policies.Originality/valueThis paper fills the knowledge gap by providing the Nigerian experience on stakeholders' perspectives of PP in developing countries.

Landuse Planning for Food Crop Areas Development Using Land Resource Evaluation Approach and GIS Application (a Case Study of Pulang Pisau District, Central Kalimantan Province)

Agustini S, Suparman S, Tridamayanti HC. 2020. Landuse planning for food crop areas development using land resource evaluation approach and gis application (a case study of Pulang Pisau District, Central Kalimantan Province). Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 64-72.In order to promote sustainable landuse, the need of landuse planning is urgently required and it can be designed based on the result of spatial land resource data management. Land resource evaluation is main component for landuse planning which this procedure was applied to determine land allocation for arable lands for rice farming development. The use of geographic information system (GIS) technology was also employed not only for spatial data management, but they could also be applied to support decision making within establishing landuse planning. The objective of this study was to allocate the arable lands for extensification and intensification regions as main part of landuse planning for food crops areas development. In the case of Pulang Pisau District, land allocation for extensification and intensification regions were mainly found in southern part and mostly located at watershed areas with each total areas respectively of 380,261 hectares (36.81%) and 29,941 hectares (2.90% of total areas of Pulang Pisau District). In order to support these potential areas, specific programs could then be formulated to increase the yield and productivity for these regions.

Landslide Hazard Risk Assessment and Landuse Planning of Mayoon, Hunza, GilgitBaltistan, Pakistan

Gilgit-Baltistan, Pakistan is highly vulnerable and hazard-prone area according to National DisasterManagerment Authority, based on frequency of avalanches, landslides, glacier lake outburst floods, rockfall and flashfloods. These hazards have been quite frequent since 2010, potentially due to changing climatic conditions and uniquetectonic setting resulting in massive destruction, economic loss and human migration. In this study, geospatial techniques(GIS/RS) were used to identify landslide hazard with elements at risk. The resultant maps will be used for betterplanning and resilience of local communities. Landslide area has been marked based on field observations (GPS data).Risk category is ranked high, medium and low based on field observations, geological setting and historical landslidedata. There are six offshoots of MKT crossing parallel to each other along KKH from Chalt to Ahmadabad. Chalt fault iscrossing nearby the Mayoon landslide, which may affect the entire valley. This study identifies landslide as a majorhazard in the area.
