Field Indicators

The objectives of this study were to develop a systematic approach to identify important soil morphological and vegetation field indicators to better target land management in degraded landscapes in a specific region. The authors were able to link the soil-landscape features to the main soil and water processes operating within the landscape. This information was used to develop a set of field indicators (e.g. soil colour) within a user-friendly soil classification key that is linked to land use options to form the basis of a manual. It was shown that information written in this format helped farmers and regional advisers to identify options for remediation of waterlogged and saline areas and to improve planning at property and catchment scales. The authors identified a series of steps to be taken in producing the manual. Steps 1–5 describe the soil layers and construct them in toposequences, which are then used to map soil types in key surrounding areas. Steps 6–9 involve the local community in developing the manual.The paper provides an account of how manuals have been produced for 2 badly degraded areas in southern Australia (Mount Lofty Ranges, South Australia; and western Victoria) and promotes the methodologies for other regions. Descriptive soil information is pictorially integrated along toposequences and applied to identify key soil features. Complex scientific processes and terminology are more simply communicated to local groups using coloured cross-sectional diagrams and photographs of soil and vegetation to overcome some of the perceived barriers to adoption of best management practices. We consider the approach should have generic application.

Forest nursery and seedling production in Leyte and Samar has been an unsustainable development and livelihood undertaking, the focus of which has been solely to serve the usual funded reforestation projects that merely recognize quantity rather than quality of planting materials produced. As a consequence, forest nursery and seedling production has never been established as a sustainable business venture, particularly at the smallholder and local community level. Forest nursery accreditation and planting stock certification is believed to be a sound strategy that can promote high quality forest tree seedling production which would eventually establish the activity as a lucrative livelihood venture especially for smallholders and local communities. The nursery accreditation and planting material certification experiences for fruit and forest trees in Leyte and Samar provide a useful basis and guide in developing and formalizing a system suitable for forest nursery accreditation and planting stock certification. The DA-BPI and DBP accreditation systems can serve as a guide in framing-up the physical standard for a viable and sustainable forest nursery business, with necessary consideration for smallholder operators. Both, however, lack the necessary technical menu and the required best management practices that are crucial in coming up with an improved nursery accreditation and planting stock certification scheme that is achievable and affordable, particularly for smallholder nursery operators.

Leaching of water-soluble contaminants has resulted in degradation of groundwater quality. This research project examined the long-term spatial variability of leaching processes within two hummocky, agricultural landscapes near Bittern Lake, in central Alberta. Analysing the distribution of soil profiles within a landscape, we created a leaching potential index based on a soil profile index (SPI) and plan curvature measurements. The index accurately differentiated locations of very high and high leaching potential from low and very low leaching potential. This index may become a useful tool to determine the variability of leaching within an agricultural landscape, to identify areas of high leaching potential, to determine agricultural best management practices, and to minimize contamination of groundwater.

Soil Saturation

Asimina triloba (L.) Dunal is an underused tree species with demonstrated potential as a new fruit crop and landscape ornamental plant. Best management practices for A. triloba are not adequately defined, particularly for field establishment in high-Na conditions characteristic of numerous southern U.S. production areas. We evaluated the growth and net macroelement uptake of field-grown A. triloba seedlings on soil amended with a single addition of gypsum at 0, 7.5, or 15.0 t·ha-1 and later receiving a regular supply of Na-affected but nonsaline irrigation water [sodium adsorption ratio (SAR) of 15.5 and electrical conductivity (EC) at 0.4 dS·m-1]. Over two growing seasons, the soil saturation extract Ca concentration increased while the soil saturation extract SAR decreased with increasing gypsum rate. Amending the soil with gypsum increased total lateral branch extension per tree by 60% to 73% and trunk cross-sectional area (TCSA) per tree by 68% to 87% above a non-gypsum-amended control treatment. Total dry matter accumulation and the net uptake of N, P, and K per tree were over 100% greater following gypsum application as compared to controls. The growth and mineral uptake-enhancing effects of gypsum were likely related to functions of Ca at the root level and on soil physical properties that should be considered in establishing young A. triloba trees with irrigation water containing high sodicity but relatively low total salinity.

Traditional Institutions

The way in which an institution treats its records is crucial for its survival in a rapidly changing society. The purpose of the study was to investigate the records management practices and challenges faced by traditional institutions of leadership and governance in Ga Molepo, Limpopo, South Africa. The researcher employed a cross-sectional survey in order to quantitatively examine the challenges faced by members of traditional councils. A researcher administered questionnaire was used as a data collection tool to study a stratified sample of 35 members from an estimated population of 350. The findings revealed patterns and trends of non-compliance with records management standards and guidelines. Although there were sporadic cases of record keeping, a greater number of respondents revealed that traditional institutions lack the facilities, equipment, education and trained/skilled personnel to apply correct records management procedures in their daily administration of their traditional communities. The main value of the study is to create awareness of records management as one of the neglected areas in traditional institutions – which are by current legislative arrangement, the closest form of leadership and governance for rural communities in light of their relationship with local municipalities and the Department of Cooperative Governance and Traditional Affairs.
