Abstract

The use of agricultural lime ameliorant or rice husk charcoal combined with inorganic fertilizers is one of the agricultural intensification efforts in peatlands. This study aimed to find out the influence of various ameliorant types and nitrogen, phosphorus, and potassium inorganic fertilizer doses application on growth and yield of maize in peatlands soil was conducted in Siantan Hulu Village, Pontianak City, West Kalimantan used. This study used a split-plot design with the main plot of ameliorant types (A) consisting of three treatments i.e. without ameliorant (A0), agricultural lime of 3 t/ha (A1) and rice husk charcoal of 3 t/ha (A2). The subplot was inorganic fertilizer doses (B) consisting of three treatments i.e. B1 = 50% of N, P, and K inorganic fertilizers, B2 = 75% of N, P, and K inorganic fertilizer, and B3 = 100% of N, P, and K inorganic fertilizers. Observation on crop growth consisted of crop height, number of leaves, leaf area, crop total fresh weight, crop total dry weight, and crop growth rate. Yield observation consisted of ear length, ear diameter, 100-dry seed weight, seed yield weight per hectare, and harvest index (IP). The results of the study indicated that rice husk charcoal application of 3 t/ha gave seed yield weight of 7.25 t/ha that was higher than that of agricultural lime that produced 6.34 t/ha seed yield and without ameliorant that produced the lowest seed yield of 4.18 t/ha. Application of N, P, and K inorganic fertilizer dose of 75% produced an insignificant difference seed yield compared to the dose of 100%, which were 6.32 t/ha and 6.69 t/ha, respectively. Therefore, the application of N, P, and K inorganic fertilizer dose of 75% is recommended as a basic of maize fertilization.

Abstract

This paper reviews the effects of habitat loss and human influence on the survival of Black-crowned cranes in Africa. Black-crowned crane is distributed through Sahel and Sudan Savannah regions of Africa, ranging from the Senegal basin and Guinea-Bissau drainage in West Africa to the western Ethiopian Highlands and south-west Rift Valley in East Africa. Habitat loss, transformation and degradation, and illegal capture and trade for pet industry, are the major threats of the species. Because of habitat loss, the population of Black-crowned cranes is declining across its home range and it is even disappearing in some countries in West Africa. It is predicted that the population decline will continue in the future due to habitat loss and trapping of cranes for domestication. The species is classified as Lower Risk from 1988 to 2000, Near Threatened from 2004 to 2008, and then Vulnerable from 2010 onwards. The rapid conversion of wetlands and intensive land use and different economic development with poor environmental protection threat the survival of Black-crowned cranes. In order to overcome the threats of Black-crowned cranes (Balearica pavonina), habitat conservation and community awareness are essential, not optional.

Abstract

Forests are one of the most valuable ecosystems in the world, containing over 60% of the world’s biodiversity. This ecosystem has multiple social economic values, apart from its intrinsic value.  Forest provides a sustainable environment. Deforestation leads to the disappearance of sustainable development. Deforestation takes place due to multiple of reasons like logging, population growth, urbanization, grazing, construction of dams and reservoirs, habitat fragmentation, slash and burn method of farming, wildfire, global warming, hydroelectric projects. Agriculture is considered to be the backbone of the Ethiopian economy and almost 85% of the societies in Ethiopia engage in agriculture.  The agricultural sector in Ethiopia in particular and in Africa, in general, is highly affected by deforestation directly and indirectly. Therefore, this paper focuses not only on the causes and consequences of deforestation but also seeks for better alternatives to tackle deforestation in Ethiopia

Abstract

Coastal areas are found in the dynamic zone at the interface between the three major natural systems of the Earth's surface. The phenomenon of shoreline change is one of the most frequent problems encountered in the coastal environment and is caused by natural processes that result in dynamic changes in the coastal area. Coastal area change can affect the vulnerability of the coastal environment and its properties, such as shoreline stabilization, flood control, sediment retention, natural protection and others. The method of integrating remote sensing data with geographic information system (GIS) techniques has been widely used to monitor and analyze the dynamics of shoreline change in coastal areas. The purpose of this study is to map and analyze the dynamics of shoreline change from 1978 to 2017 in the study area. An approach combining spectral value index and visual interpretation of Landsat images was used and proposed to indicate the separation of land and water bodies, for shoreline extraction. The normalized difference water index (NDWI) can be used as a spectral value index approach for differentiating land and water bodies. Furthermore, the analysis of shoreline changes was performed using the digital shoreline analysis system (DSAS). Based on calculations made using DSAS, it can be seen that the pattern of coastline change tends to be dominated by offshore erosion. The results of this study may also be important as input data for coastal hazard assessment as part of the effort to overcome the problem of flood tides.
