“…Biological agents are examples of microorganism products that can be an alternative to synthetic materials. The existence of biological agents is very important for biosafety and biosecurity (Chikowore et al, 2023;David and Lake, 2023). Biological agents are part of the conservation of soil and water and the presence of plant-disturbing organisms by using useful microorganisms and organic materials (Habriantono et al, 2023b;Prastiwi et al, 2023).…”

The current challenges of industrial agriculture focus on environmental safety. Water quality is an indicator of environmental sustainability. The cultivation system has an impact on water quality. The aim of this study is to assess the water quality of agricultural systems. Anthropogenically, agricultural activities have an impact on environmental aspects. Identification of agricultural systems is clustered into organic and non-organic agriculture. The agricultural system in Indonesia is regulated based on SNI 6729;2016. Water sampling was carried out at three points, including upstream, middle (irrigation), and downstream (river). Water sampling at each point was repeated three times. Assessment of the physical quality of water using the Combo Quality Meter. Water samples for chemical and biological analysis at the Environmental Laboratory, Perum. Jasa Tirta 1. Determination of water quality standards refers to Government Regulation No. 82 of 2001. In the upstream section, pollution can be seen in the biological oxygen demand (BOD) indicator, with an average of 15.03 mg L-1 for organic and conventional systems. The phosphate indicator averaged 1.96 mg L-1. In the middle section (irrigation), the pollution indicators for BOD, phosphate, and total Coliform parameters were 6.76 mg L-1 for the organic system, 7.37 mg L-1 for the non-organic system, and 1,290 CFU mL-1. In the downstream (river), pollution indicators consist of total suspended solids (TSS), BOD, chemical oxygen demand (COD), and total Coliform. Anthropogenic identification for clustering agricultural systems at the research location uses stratified disproportional sampling. The results of this research provide recommendations for water quality management for sustainable agricultural environmental management.

Biological invasions can have major social-ecological consequences for rural communities across the world. However, the dimensions (characteristics, infestation and socio-ecological impacts) of emerging invasive alien plants are often less known and urgent information is needed to guide policy and management. In light of this, this paper assesses the social-ecological impacts of Vernonanthura polyanthes, an emerging invasive alien plant found in a Zimbabwean upland landscape which supports conservation and livelihoods. The paper employs qualitative methods—community mapping, time series analysis, and key informant interviews—involving individuals from diverse socio-economic backgrounds, to examine the socio-ecological and economic implications of V. polyanthes and its management in Chimanimani, Zimbabwe. We found that there are nuanced perspectives regarding this invasive alien plant among different socio-economic groups in the region who have different experiences of living with V. polyanthes. Some are embracing it for apiculture, firewood, and ethnomedicine while, on the other hand, some see the tree as negatively affecting key livelihoods (crop farming, pastoralism, and tourism) that are common in the region. Local people also identified that V. polyanthes is associated with ecological impacts that include loss of biodiversity, promoting pests, and negatively affecting watersheds and associated water sources. These mixed experiences concerning the plant are leading to different management practices, in turn inducing some conflicts among various actors. Based on our findings, we suggest more should be done to better manage this invasive alien plant in the region before negative impacts become too great, particularly in protected areas.
