“…The physical properties of soil used as an indicator of soil quality are soil texture with the pipette method, soil humidity with the gravimetric method, bulk density (BD) with the earthen lump method, particle density (PD) with the pycnometer method, and porosity the method used refers to the study [23]. Porosity describes the percentage of pores in the soil, the rate of total pores occupied by water and air, compared to the total volume of the soil.…”

Assessing soil quality is integral to determining the appropriateness of soil management practices. Agroforestry, a tillage system that strategically integrates tree plantations with annual crops, has a potential impact on soil quality through the augmentation of soil organic matter derived from litter deposited on the soil surface. This study aims to calculate the soil quality index and evaluate the soil quality status across various agroforestry types. The research was conducted in Sumberejo Village, Batuwarno District, Wonogiri Regency, Indonesia, focusing on distinct agroforestry types: teak agroforestry, mahogany agroforestry, mixed agroforestry, and dry land-representing an area where agroforestry systems are not implemented. Fourteen indicators were utilized for the assessment, and subsequent Principal Component Analysis was employed to select the Minimum Data Set. The chosen indicators included soil macrofauna diversity index, cation exchange capacity (CEC), available soil phosphorus (P), total soil nitrogen (N), soil organic carbon (C), soil moisture, base saturation (BS), available soil potassium (K), particle density, pH, and porosity. The findings reveal that the soil quality across all four types of agroforestry is low, with mahogany agroforestry exhibiting the highest soil quality index at 0.35. The soil quality index for teak agroforestry, mixed agroforestry, and dry land was 0.33 each. The study concludes that the primary determinant of soil quality is the cation exchange capacity (CEC).

“…Coastlines, and the banks of lakes and rivers, provide ideal places for human development, with ready access to a source of food, water, building materials, and transport (Compagno & Cook, 1995). Land clearing for urbanization and agricultural purposes has led to increased sedimentation, and pollution from fertilizers, pesticides, and heavy metals, reducing habitat quality and affecting primary production within ecosystems (Acero Triana, Chu & Stein, 2021). The widespread construction of dams has further reduced habitat quality through altering flow and sediment regimes, resulting in population fragmentation (Grill et al, 2019).…”

Globally, freshwater environments are imperilled, with freshwater vertebrate species declining at twice the rate of marine and terrestrial populations. Non‐marine elasmobranchs (freshwater obligates and euryhaline generalists) remain understudied and overlooked by conservation efforts. This study aimed to adapt and apply a vulnerability assessment framework to understand the conservation priorities of Indo‐West Pacific non‐marine elasmobranch species. An exposure sensitivity adaptability (ESA) framework was used to assess vulnerability to environmental threats, and an exposure susceptibility productivity (ESP) framework was used to assess vulnerability to fisheries. Resulting species vulnerabilities were categorized into three conservation priority tiers. The general patterns of conservation priority tiering were as follows: (i) large‐bodied euryhaline species occurring in densely populated nations had the highest ESA and ESP vulnerabilities; (ii) freshwater obligates also had high ESA vulnerability rankings, although ESP vulnerability rankings were lower as their smaller body sizes suggest increased population productivity and higher potential for resilience; and (iii) euryhaline species with large range proportions in northern Australia had moderate to low vulnerability rankings across ESA and ESP assessments, as these species benefit from reduced fisheries mortality compared with species occurring in other regions. The outcomes from the vulnerability assessment framework for the conservation priority rankings of species corresponded with their respective International Union for Conservation of Nature (IUCN) Red List status, whereby priority 1 and 2 species also have elevated extinction risks. Environmental threats were at high or moderate levels in all nations assessed, while Cambodia, China, Malaysia, and Myanmar face the highest pressure from inland fisheries. The major knowledge gaps identified included species‐specific productivity estimates, population dynamics (population movements and habitat requirements), and information on mortality from the threats considered. The present ESA–ESP framework was effective for the broad and data‐poor context of Indo‐West Pacific non‐marine elasmobranchs, and the results will be useful for guiding future conservation planning for high‐priority species and nations.
