The Impact

Biodiversity loss is accelerating rapidly in response to increasing human influence on the Earth’s natural ecosystems. One way to overcome this problem is by focusing on places of human interest and monitoring the changes and impacts on the biodiversity. This study was conducted at six sites within the influence area of the Santo Antônio Hydroelectric Power Plant in the margins of the Madeira River in Rondônia State. The sites cover a latitudinal gradient of approximately 100 km in the Brazilian Amazon Basin. The sampling design included six sampling modules with six plots (transects) each, totaling 30 sampling plots. The transects were distributed with 0 km, 0.5 km, 1 km, 2 km, 3 km and 4 km, measured perpendicularly from the river margin towards the interior of the forest. For sampling the ground-dwelling ants, the study used the ALL (ants of the leaf litter) protocol, which is standardized globally in the inventories of ant fauna. For the purpose of impact indicators, the first two campaigns (September 2011 to November 2011) were carried out in the pre-filling period, while campaigns 3 to 10 (February 2012 to November 2014) were carried out during and after the filling of the hydroelectric reservoir. A total of 253 events with a total of 9,165 occurrences were accounted during the monitoring. The ants were distributed in 10 subfamilies, 68 genera and 324 species/morphospecies. The impact on ant biodiversity during the periods before and after filling was measured by ecological indicators and by the presence and absence of some species/morphospecies. This is the first study, as far as we know, including taxonomic and ecological treatment to monitor the impact of a hydroelectric power plant on ant fauna. Until recently, most studies conducted on hydroelectric plants, located in the Amazon Basin, were carried out after the implementation of dams in order to assess their impacts on the environment and biodiversity (Benchimol and Peres 2015, Latrubesse et al. 2017, Sá-Oliveira et al. 2015). Recent studies on dam impacts have begun to be conducted prior to dam implementation (e.g. Bobrowiec and Tavares 2017, Fraga et al. 2014, Moser et al. 2014), thus providing a better overview of the impact and a better assessment of its magnitude.

Choir IR, Iskandar J, Parikesit, Partasasmita R, Husodo T, Kumoro J, Megantara EN. 2018. The local management andsustainability of swidden farming in the Villages of Bojongsalam and Sukaresmi, Upper Cisokan Watershed, West Java, Indonesia.Biodiversitas 19: 1054-1065. In the past, the swidden farming (huma or ladang) system had been predominantly practiced by villagepeople of West Java. Nowadays, however, the huma farming has rarely been practiced by the village people of West Java due to thegovernment policy, and environmental and socioeconomic changes. The local community who reside in the Villages of Bojongsalamand Sukaresmi, the upper stream of Cisokan, West Java, Indonesia, has still practiced both the wet rice field (sawah) and the humafarming in the private land, production forest of a state-owned forest company (Perhutani), and a state-owned electric company (PLN)project land. Recently some areas of the huma land have been used for the project of the Hydroelectric Power Plant of the UpperCisokan Pumped Storage (UCPS). As a result, the sustainability of huma system of the local people of Bojongsalam and Sukaresmi hasbeen seriously disturbed. The aims of this study were to elucidate the local management of the huma farming systems that areundertaken by local people of Bojongsalam and Sukaresmi Villages, and to analyze the sustainability of the huma farming of localpeople of Bojongsalam and Sukaresmi Villages as affected by the UCPS Hydroelectric Power Plant project. The qualitative method wasused, while several techniques of collecting the primary data, namely observation and in-depth interviews with informants were appliedin this study. The results of study showed that the local management of the huma farming has been annually undertaken by the localpeople of Bojongsalam and Sukaresmi, including deciding the location of huma plot, preparing the land (cutting shrubs and burningvegetation biomass), planting rice (ngaseuk) and other annual crops, weeding (ngored) and providing chemical fertilizers (mupuk),controlling pests, harvesting rice (dibuat), and fallowing land. Based on analysis of the emergent properties of the agroecosystem ofhuma farming, it can be predicted that productivity, stability, equitability, and sustainability of the huma farming systems ofBojongsalam and Sukaresmi Villages tend to be low in the near future due to the impact of UCPS Hydroelectric Power Plant project.

Abstract. Determination of the catchment area is the starting point in most hydrological analyses. It serves as a basis for many hydrological and water resources management calculations. The catchment boundaries and areas in karst regions are often fragmented and not accurately known. They can change over time due to natural and anthropogenic causes. Natural and man-made processes cause changes of catchment area on different time and space scales. Human intervention, especially construction of dams and reservoirs, as well as interbasin water transfer through long tunnels and pipelines can introduce instantaneous, definite and hazardous change. This paper presents seven examples of natural and anthropogenic factors which influenced changes of catchment area in the Dinaric karst: 1) Closing of the Obod Estavelle in the Fatniceko polje; 2) Operation of the Zakucac hydroelectric power plant on the Cetina River; 3) Problems caused by Salakovac Reservoir; 4) Catastrophic flooding in the Cetinje Polje; 5) Regulation and canalization of the Trebišnjica River; 6) Building of the underground hydroelectric power plant Ombla; 7) An earthquake in Southern Croatia and Western Herzegovina.
