Silica sand mining in Shankargarh, Prayagraj, India area has led to extensive ecological destruction, environmental degradation and erosion of traditional values in the society. Therefore, an integrated organic and socioeconomic approach is urgently required to bioreclaim degraded mine sites.The most common problems linked with degraded land rehabilitation failures are frequently associated with improper selection of plantation species. Subsistence utility preferences of local people are major acclaimed and convincing reasons in the selection of valuable tree species for Bioreclamation. Socioeconomic Survey were carried out in the nearby villages of Silica mining area to study the existing resources of the area, social structure of the community, dependence on forest and species preferred by the local people. Consequently, a Utility Value Index (UVI) framework was conceptualized, designed and subsequently developed to identify species preferred by the local people and highly valued for supporting their livelihood.

Tin mining is one of the land uses that causes physical damage to the land. Degraded land due to the mining activity requires a conservation. Conservation of post-tin mining land in Perimping Sub Watershed consists of reclamation and revegetation by planting kinds of fast-growing plants and cover crops. As land management, conservation is conducted to establish the diversity of land cover and to recover the land quality to be more productive for the local people. This study aimed to analyze the land cover change in land conservation of post-tin mining area. Moreover, also to identify the condition of post-tin mining land which has been conserved. Land cover map of 2011, 2014, and 2017 were produced from Google Earth imagery. Field validation was conducted to determine the existence of cover types on conservation land and interviews were conducted to find other impact of post-tin mining land conservation for local people. The result shows that land cover change in post-tin mining land conservation area over 6 years dominated by escalation of land cover such as mining, plantations. Monitoring of land cover change in conservation area is important to measure the effectivity of land conservation in post-tin mining area.

Abstract Background: In Ethiopia, about 92.3% of all the biomass energy is consumed by domestic households and the demand is growing from 10-14%. However, there are little/no practical experiences or documented indigenous knowledge on how traditional people identify and select high biomass producing plant species with short rotation periods at Boset District. Therefore, the present study was aimed at: (1) selecting and documenting high biomass energy producing plant species at Boset District; (2) identifying major predictor variables that influence the prioritization and selection of species; and (3) develop a Generalized Linear Model (GLM) to predict the selection of species. Methods: A total of 96 informants comprising 59 men and 37 women between the ages of 18 and 81 were sampled. Data were collected using structured interviews, guided field walk, discussions and field observations. Results: Collected data indicated that 88.5% of the informants involved in firewood collection, while 90% practiced charcoal making. A total of 1533.60 Birr per household on average was earned annually from this activity. A total of 25 firewood and/or charcoal plant species were identified and documented at Boset District. Of these, Acacia senegal, Acacia tortilis and Acacia robusta were the three best prioritized and selected indigenous high biomass producing species. Prosopis juliflora, Parthenium hysterophorus, Azadirachta indica, Calotropis procera, Cryptostegia grandiflora, Lantana camara and Senna occidentalis further grouped under introduced fuelwood species. Prediction of GLM assured sampled Kebeles and source of income generated from fuelwood species positively and significantly (p<0.001) related to selection of species. Higher efficiency to provide energy and heat; little or no smoke or soot; easier to cut and split the wood and easier availability were some of the main selection criteria. Conclusions: This study provides valuable information in selection and documenting of high biomass producing plant species for proper management and sustainable use at Boset District. The three most selected species (A. senegal, A. tortilis and A. robusta) should be further evaluated at laboratory to determine their energy values.

Paropsisterna variicollis, the eucalyptus variegated beetle, was first detected in New Zealand in 2016. It threatens a growing eucalyptus forestry sector through larvae and adults causing significant defoliation to important plantation species. This work aimed to clarify the identification and origin of the New Zealand incursion to inform selection of suitable biological control agent(s). Australian and New Zealand specimens from the Paropsisterna obovata-variicollis-cloelia species complex were analysed by PCR and sequencing of two genetic loci, cytochrome c subunit I (COI) and cytochrome b (Cyt b). Molecular analysis of both genetic regions showed three major clusters of diversity. Cluster 1, proposed as Paropsisterna variicollis, had maximum 1.3% genetic variation and was collected from New Zealand, Western Australia and from geographically diverse locations in eastern Australia. Taxonomic results identified distinctive phenotypes of other closely related beetle species, assisting in proposing Cluster 2 as Paropsisterna near decolorata and Cluster 3 as Paropsisterna agricola. Molecular results were compared to morphological structures on adult beetles.

River is the most important things for the human life, one of the components environmental especially for whom whose living in the city and Ciliwung river is one of the major river beside of others 13 rivers. Bamboo trees, bananas, cotton, gempol and elo are the common flora were dominate plants along the riverbanks (gempol and elo taken from the local people words). Based from interview with some local citizens in the Ciliwung riverbank which pas through the district of Pangadegan (South Jakarta), Ficus racemosa L (elo tree) is the most important plant which can withstand river erosion and could maintained the riverbanks during flood and continued by taking sample that plant on that district for need of analysis and identification. From the calculation Gigantochloa apus types stake has the highest INP value to the over all plot of 65.43% while INP Ficus racemosa is still low, but Ficus racemosa can be one alternative plant for conservation in the Ciliwung river, because Ficus racemosa has strong roots. However the selection of other plants such as bamboo trees is more effective because it has fast growth. Therefore, by combining the types of plants that role as conservation may be a solution.

The purpose of the research reported in this paper was to evaluate the possibility of growing vegetable plants in pots and containers by optimizing the choice of species and cultivars and the type of pot or container based on the information available in the literature and on the basis of our own experience. Taking into account the purpose and objectives of this paper, the study is structured to respond to each  bjective considered. Information on crops in pot and containers shows that if the climatic conditions necessary for growth and development areoptimal, basically any vegetable species can be grown in this system (Purnell, 2007). Concerning the pots in which vegetable plants can be grown, they are diverse and may be chosen specifically for this type of culture or can be assigned to provide the space necessary for plant growth for different species.

The energy demand in Indonesia has increased significantly with its population growth, urbanization, and economic development. The growing concern of meeting energy demand while reducing dependency on fossil fuels has resulted in an increasing demand for renewable energy. As a country with a rich biomass base, bioenergy is now an important component of Indonesia’s energy agenda. However, a crucial problem in bioenergy production is the selection of species that can provide a sustainable supply of feedstock without having an impact on food security and the environment. In this context, we discuss the characteristics and benefits of using bamboo, a perennial grass, as a potential species for bioenergy feedstock in Indonesia. We describe the fuel characteristics of bamboo along with the possibility to align its cultivation, production, and usage with environmental and developmental agendas which makes it a suitable bioenergy crop in the country. In addition, its ability to grow on degraded lands, fast growth, long root system, and easy maintenance prove it as a powerful ally for the restoration of degraded land. We recommend in-depth research on the social, ecological, and economic feasibility of using this species for bioenergy production.

AbstractCurrent fishing practices often do not allow adequate selection of species or sizes of fish, resulting in unwanted catches, subsequently discarded, with the consequent negative effects on both marine communities and fisheries profitability. The cross-analysis of density patches of potential unwanted catches and distribution of fishing effort can support the identification of spatial-temporal hot-spots in which the fishing pressure should be reduced to limit the amount of discards. The MinouwApp represents a technological and methodological framework to bring different, and structurally complex, sources of georeferenced data together into a simple visual interface aiming to interactively explore temporal ranges and areas of interest. The objective is to improve the understanding of fisheries dynamics, including discards, thus contributing to the implementation of discard management plans in a context of participative, ecosystem-based fisheries management strategies.
