Abstract

A sediment trap with bamboo materials can be utilized as one alternative of eco-friendly technology to reduce the ero-sion that occurred on agricultural land. This study aims to determine the most efficient form of that sediment trap in the field. Location study is in the Tulungrejo Village, Batu, Indonesia, which has andosol soil type and 35 cases of a landslide in 2013. Three forms of sediment traps were used (square, trapezoidal, and stratified type) with the purpose to find the most effective form. It is obtained that the most effective sediment trap is a stratified form with the 31.91% effectiveness or able to withstand sediment of 25.02 kg, while the adequate number is two pieces with the ability to withstand the most consider-able sediment of (91.70%). Therefore this stratified form of sediment traps is effective in erosion prevention on agriculturalland in the study area. For further development, it is required to test out the variations of the contents in a broader area with a more varied level of the slope.

Abstract

This paper studies the assessment of sensitivity to land degradation of Deliblato sands (the northern part of Serbia), as a special nature reserve. Sandy soils of Deliblato sands are highly sensitive to degradation (given their fragility), while the system of land use is regulated according to the law, consisting of three zones under protection. Based on the MEDALUS approach and the characteristics of the study area, four main factors were considered for evaluation: soil, climate, vegetation and management. Several indicators affecting the quality of each factor were identified. Each indicator was quantified according to its quality and given a weighting of between 1.0 and 2.0. ArcGIS 9 was utilized to analyze and prepare the layers of quality maps, using the geometric mean to integrate the individual indicator map. In turn, the geometric mean of all four quality indices was used to generate sensitivity of land degradation status map. Results showed that 56.26% of the area is classified as critical; 43.18% as fragile; 0.55% as potentially affected and 0.01% as not affected by degradation. The values of vegetation quality index, expressed as coverage, diversity of vegetation functions and management policy during the protection regime are clearly represented through correlation coefficient (0.87 and 0.47).

Abstract

The 15th of United Nations’ Sustainable Development Goals (SDGs) aims to protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss. This paper investigates the approach adopted by indigenous peoples for conservation of woody plant species diversity in some selected spots in Abia State, Southeastern Nigeria.
Relying on mixed method approach to research, data collection comprising field observation, ground truthing, plant species inventory, and key-informant interviews and analysis of data, two spots were purposively sampled, one from each of the two LGAs; Mbom in Bende LGA and Amangwu in Ohafia Local Government Area (LGA). A 50 × 20 m quadrat was sampled from each site, from where plant species inventory was undertaken. Shannon– Wiener diversity index (H’) was used to analyse the data.
The result of Shannon–Wiener diversity index, shows that the diversity indices of the plant species for the two sites were 3.20 (Mbom) and 3.95 (Amangwu) respectively. The people of Bende and Ohafia LGAs employ some traditional laws to ensure conservation of woody plant species so as to achieve goal 15th of the SDGs. This paper advocates sustenance of those traditional laws that encourage conservation of woody plant species in the study area with enforceable sanctions to deter defaulters.
