Abstract: Fluventic Eutrudepts is widely distributed in Indonesia but has low fertility to be used for agricultural activity. Soil nutrition availability could be enhancing by fertilization. The objective of this research was to determine the effect of water hyacinth compost and N, P, K, S fertilizer dosage on nitrogen rate in soil and plant, so quantity and quality in shallot. The experiment was held from March until June 2020 at Soil Chemistry, and Plant Nutrition Experimental Field, Agriculture Faculty, Universitas Padjadjaran, Jatinangor, Sumedang, at an altitude about ± 745 m above sea levels. This research used experiment method with Randomized Block Design, had seven treatments and four replications. The treatments were: control, 1 dosage of N, P, K, S fertilizer recommendation, the dosage of N, P, K, S fertilizer (1, ¾); and dosage of water hyacinth compost (½, 1, 1½). The result of this experiment showed that water hyacinth compost and N, P, K, S fertilizer dosage significantly affected on nitrogen rate in soil and crops, quantity and quality of shallots. The combination of ½ dosage of water hyacinth compost and ¾ dosage of N, P, K, S fertilizer effectively gave a better effect than other treatments.

Abstract: The need for sustainable and green cities highlights the importance to improve plant species diversity in urban areas. We assessed the phytodiversity of three management units (strata) to enhance plant species conservation planning in Lokossa City. A forest inventory was conducted in each stratum based on one-hectare sample plots. Fifty plots were distributed following a stratified random sampling approach. We found that 53 plants species belonging to 46 genera and 22 families were established in the strata. However, the flora of the city was mixed with 50.94% of native plant species. The dominant families were Leguminosae, Arecaceae, Malvaceae, Moraceae, Combretaceae, Lamiaceae and Myrtaceae. The ten most important plant species accounted for 69.31% of the total abundance. Khaya senegalensis (Desv.) A. Juss. and Mangifera indica L. were dominant plant species. Ubiquitous species accounted for 54.72% of species pool and 82.92% of all individuals. The flora of residential zone was more diversified than those in road buffer and institutional zones. Which contributed to 60.27% of all individuals. The road buffer and institutional zones flora were quite similar. Therefore, we suggested that the planting and monitoring projects should be detailed and budgeted with reference to plausible scientific knowledge in the city development plan. The creation of participatory botanical gardens at the city neighborhoods scale. The integration of the flora of residential zone in species conservation projects in order to increase global diversity and storage of biomass in the city.

Abstract: Indigenous peoples are a major constituent in the inter-play that involves management, protection, conservation and sustainable utilization of natural resources globally. Several UNFCCC Conference of Parties (COPs) negotiation events have been held worldwide to agree on climate change actions aimed at reducing global emissions. Qualitative research using discourse and content analysis (DA and CA) was carried out to evaluate trends and patterns of COPs discussions from 2009 (COP 15) to 2015 (COP 21) in including the rights of indigenous peoples in their sessions using official documents generated and published on the UNFCCC official web portal. The sensitivities and rights of indigenous people were not taken into account up and until the Copenhagen Accord of 2009 (COP 15). COP 16 registered the highest WFC “Indigenous People” of 10, followed by COP 20 (7) and then COP 21 (5). COP 15 had the least WFC of 2. The rights of Indigenous People are more expressed in Financing and Capacity Building areas of the UNFCCC and least in Mitigation and Adaptation issues. The right to food and land has seldom been addressed in the 7 COPs while the right to health has been addressed only once during COP 21. Only participation and traditional knowledge have improved over time. There is a serious need to operationalize the Cancun Agreement of 2010 (COP 16) on the rights of indigenous peoples.

Abstract: Competition for grazing resources has been speculated to cause grazing conflicts in Northern Kenya. This study evaluated how pastoral communities compete for seasonal resources leading to grazing conflicts in the region. It was anchored on the theory that competition for limited resources led to livestock movements within and out of conservancies thus triggering conflicts on grazing resources. The study used mixed methods of ecological, remote sensing and social survey design. Purposive sampling was used to select four conservancies out of a population of fifteen, where three of them were community-managed while the fourth was privately owned. Lists of grazing committees were obtained, and systematic sampling used to select a population of 106 respondents. Self-administered questionnaires, focused group discussions and content analysis of literature were used to collect social data. The data was analyzed using Statistical Package for Social Sciences (SPSS) version 26. Ecological and bio-physical data on land-use trends were obtained using remote sensing and analyzed using Quantum GIS. The results established that competition accounted for about 45% of variability of grazing conflicts (R2=0.449). It was found that community conservancies had the greatest effects of competition for forage compared to private conservancies. The results were modelled to determine how competition can predict grazing conflicts in the region. The study recommended further investigations on the effects of other factors contributing to grazing conflicts that were not considered, while building capacity to pastoral communities to adhere to grazing plans in order to stem over-grazing and migrations.
