The human right to water has recently been recognised by both the United Nations General Assembly and the Human Rights Council. As the mining industry interacts with water on multiple levels, it is important that these interactions respect the human right to water. Currently, a disconnect exists between mine site water management practices and the recognition of water from a human rights perspective. The Minerals Council of Australia (MCA) Water Accounting Framework (WAF) has previously been used to strengthen the connection between water management and human rights. This article extends this connection through the use of a Social Water Assessment Protocol (SWAP). The SWAP is scoping tool consisting of a set of questions classified into taxonomic themes under leading topics with suggested sources of data that enable mine sites to better understand the local water context in which they operate. Three of the themes contained in the SWAP – gender, Indigenous peoples and health – are discussed to demonstrate how the protocol may be useful in assisting mining companies to consider their impacts on the human right to water.

Water to air methane emissions from freshwater reservoirs can be dominated by sediment bubbling (ebullitive) events. Previous work to quantify methane bubbling from a number of Australian sub-tropical reservoirs has shown that this can contribute as much as 95% of total emissions. These bubbling events are controlled by a variety of different factors including water depth, surface and internal waves, wind seiching, atmospheric pressure changes and water levels changes. Key to quantifying the magnitude of this emission pathway is estimating both the bubbling rate as well as the areal extent of bubbling. Both bubbling rate and areal extent are seldom constant and require persistent monitoring over extended time periods before true estimates can be generated. In this paper we present a novel system for persistent monitoring of both bubbling rate and areal extent using multiple robotic surface chambers and adaptive sampling (grazing) algorithms to automate the quantification process. Individual chambers are self-propelled and guided and communicate between each other without the need for supervised control. They can maintain station at a sampling site for a desired incubation period and continuously monitor, record and report fluxes during the incubation. To exploit the methane sensor detection capabilities, the chamber can be automatically lowered to decrease the head-space and increase concentration. The grazing algorithms assign a hierarchical order to chambers within a preselected zone. Chambers then converge on the individual recording the highest 15 minute bubbling rate. Individuals maintain a specified distance apart from each other during each sampling period before all individuals are then required to move to different locations based on a sampling algorithm (systematic or adaptive) exploiting prior measurements. This system has been field tested on a large-scale subtropical reservoir, Little Nerang Dam, and over monthly timescales. Using this technique, localised bubbling zones on the water storage were found to produce over 50,000 mg m-2 d-1 and the areal extent ranged from 1.8 to 7% of the total reservoir area. The drivers behind these changes as well as lessons learnt from the system implementation are presented. This system exploits relatively cheap materials, sensing and computing and can be applied to a wide variety of aquatic and terrestrial systems.

Montserrat now provides one of the most complete datasets for understanding the character and tempo of hazardous events at volcanic islands. Much of the erupted material ends up offshore, and this offshore record may be easier to date due to intervening hemiplegic sediments between event beds. The offshore dataset includes the first scientific drilling of volcanic island landslides during IODP Expedition 340, together with an unusually comprehensive set of shallow sediment cores and 2-D and 3-D seismic surveys. Most recently in 2013, Remotely Operated Vehicle (ROV) dives mapped and sampled the surface of the main landslide deposits. This contribution aims to provide an overview of key insights from ongoing work on IODP Expedition 340 Sites offshore Montserrat.Key objectives are to understand the composition (and hence source), emplacement mechanism (and hence tsunami generation) of major landslides, together with their frequency and timing relative to volcanic eruption cycles. The most recent major collapse event is Deposit 1, which involved ~1.8 km cubed of material and produced a blocky deposit at ~12-14ka. Deposit 1 appears to have involved not only the volcanic edifice, but also a substantial component of a fringing bioclastic shelf, and material locally incorporated from the underlying seafloor. This information allows us to test how first-order landslide morphology (e.g. blocky or elongate lobes) is related to first-order landslide composition. Preliminary analysis suggests that Deposit 1 occurred shortly before a second major landslide on the SW of the island (Deposit 5). It may have initiated English's Crater, but was not associated with a major change in magma composition. An associated turbidite-stack suggests it was emplaced in multiple stages, separated by at least a few hours and thus reducing the tsunami magnitude. The ROV dives show that mega-blocks in detail comprise smaller-scale breccias, which can travel significant distances without complete disintegration. Landslide Deposit 2 was emplaced at ~130ka, and is more voluminous (~8.4km cubed). It had a much more profound influence on the magmatic system, as it was linked to a major explosive mafic eruption and formation of a new volcanic centre (South Soufriere Hills) on the island. Site U1395 confirms a hypothesis based on the site survey seismic data that Deposit 2 includes a substantial component of pre-existing seafloor sediment. However, surprisingly, this pre-existing seafloor sediment in the lower part of Deposit 2 at Site U1395 is completely undeformed and flat lying, suggesting that Site U1395 penetrated a flat lying block. Work to date material from the upper part of U1396, U1395 and U1394 will also be summarised. This work is establishing a chronostratigraphy of major events over the last 1 Ma, with particularly detailed constraints during the last ~250ka. This is helping us to understand whether major landslides are related to cycles of volcanic eruptions.

The use of nitrification inhibitors, in combination with ammonium based fertilisers, has been promoted recently as an effective method to reduce nitrous oxide (N2O) emissions from fertilised agricultural fields, whilst increasing yield and nitrogen use efficiency. Vegetable cropping systems are often characterised by high inputs of nitrogen fertiliser and consequently elevated emissions of nitrous oxide (N2O) can be expected. However, to date only limited data is available on the use of nitrification inhibitors in sub-tropical vegetable systems. A field experiment investigated the effect of the nitrification inhibitors (DMPP & 3MP+TZ) on N2O emissions and yield from a typical vegetable production system in sub-tropical Australia. Soil N2O fluxes were monitored continuously over an entire year with a fully automated system. Measurements were taken from three subplots for each treatment within a randomized complete blocks design. There was a significant inhibition effect of DMPP and 3MP+TZ on N2O emissions and soil mineral N content directly following the application of the fertiliser over the vegetable cropping phase. However this mitigation was offset by elevated N2O emissions from the inhibitor treatments over the post-harvest fallow period. Cumulative annual N2O emissions amounted to 1.22 kg-N/ha, 1.16 kg-N/ha, 1.50 kg-N/ha and 0.86 kg-N/ha in the conventional fertiliser (CONV), the DMPP treatment, the 3MP+TZ treatment and the zero fertiliser (0N) respectively. Corresponding fertiliser induced emission factors (EFs) were low with only 0.09 - 0.20% of the total applied fertiliser lost as N2O. There was no significant effect of the nitrification inhibitors on yield compared to the CONV treatment for the three vegetable crops (green beans, broccoli, lettuce) grown over the experimental period. This study highlights that N2O emissions from such vegetable cropping system are primarily controlled by post-harvest emissions following the incorporation of vegetable crop residues into the soil. It also shows that the use of nitrification inhibitors can lead to elevated N2O emissions by storing N in the soil profile that is available to soil microbes during the decomposition of the vegetable residues over the post-harvest phase. Hence the use of nitrification inhibitors in vegetable systems has to be treated carefully and fertiliser rates need to be adjusted to avoid excess soil nitrogen during the postharvest phase.

The microbial mediated production of nitrous oxide (N2O) and its reduction to dinitrogen (N2) via denitrification represents a loss of nitrogen (N) from fertilised agro-ecosystems to the atmosphere. Although denitrification has received great interest by biogeochemists in the last decades, the magnitude of N2lossesand related N2:N2O ratios from soils still are largely unknown due to methodical constraints. We present a novel 15N tracer approach, based on a previous developed tracer method to study denitrification in pure bacterial cultures which was modified for the use on soil incubations in a completely automated laboratory set up. The method uses a background air in the incubation vessels that is replaced with a helium-oxygen gas mixture with a 50-fold reduced N2 background (2 % v/v). This method allows for a direct and sensitive quantification of the N2 and N2O emissions from the soil with isotope-ratio mass spectrometry after 15N labelling of denitrification N substrates and minimises the sensitivity to the intrusion of atmospheric N2 at the same time. The incubation set up was used to determine the influence of different soil moisture levels on N2 and N2O emissions from a sub-tropical pasture soil in Queensland/Australia. The soil was labelled with an equivalent of 50 μg-N per gram dry soil by broadcast application of KNO3solution (4 at.% 15N) and incubated for 3 days at 80% and 100% water filled pore space (WFPS), respectively. The headspace of the incubation vessel was sampled automatically over 12hrs each day and 3 samples (0, 6, and 12 hrs after incubation start) of headspace gas analysed for N2 and N2O with an isotope-ratio mass spectrometer (DELTA V Plus, Thermo Fisher Scientific, Bremen, Germany(. In addition, the soil was analysed for 15N NO3- and NH4+ using the 15N diffusion method, which enabled us to obtain a complete N balance. The method proved to be highly sensitive for N2 and N2O emissions detecting N2O emissions ranging from 20 to 627 μN kg-1soil-1hr-1and N2 emissions ranging from 4.2 to 43 μN kg-1soil-1hr-1for the different treatments. The main end-product of denitrification was N2O for both water contents with N2 accounting for 9% and 13% of the total denitrification losses at 80% and 100%WFPS, respectively. Between 95-100% of the added 15N fertiliser could be recovered. Gross nitrification over the 3 days amounted to 8.6 μN g-1 soil-1 and 4.7 μN g-1 soil-1, denitrification to 4.1 μN g-1 soil-1 and 11.8 μN g-1 soil-1at 80% and 100%WFPS, respectively. The results confirm that the tested method allows for a direct and highly sensitive detection of N2 and N2O fluxes from soils and hence offers a sensitive tool to study denitrification and N turnover in terrestrial agro-ecosystems.

UNCITRAL’s operation as a subsidiary of the UN General Assembly, tasked to unify and harmonise international trade law is a necessary and indispensable element of the UN’s mandate to maintain international peace and security. Strong legal frameworks which are compatible with those of international trading partners often accompany accelerated growth in economic capacity and stability. Over time, access to markets and resultant growth in economic and human development creates a disincentive for instability as incomes and standards of living rise. Human and economic development, facilitated by a modernised and just legal framework that is available to the broadest range of recipients goes hand in hand with the maintenance of domestic and regional peace, particularly in regions such as the ASEAN , one of the fastest growing in the world covering approximately 30% of global population and with a number of strong global economic neighbours including Japan, Korea, China (to the north), Australia (to the south) and Singapore (to the west). In an increasingly interconnected world, the ability of government, enterprise and individuals to participate in the global supply chain offers opportunities for economic growth and development. Over its almost 50 years of operations, UNCITRAL has produced a range of important texts that are designed to underpin world trade. A key implicit assumption underpinning the development of UNCITRAL texts is that the texts, once adopted can and will be applied in adopting states.

Since the 1998 Rome Statute recognized widespread and systematic acts of sexual and gender-based violence (SGBV) as an act of genocide, a war crime and crime against humanity, the last decade has seen historic recognition that egregious acts of sexual violence merit international political and legal attention (UN General Assembly, 1998). Notably there are now no fewer than seven United Nations Security Council resolutions on the cross-cutting theme of Women, Peace and Security.

In September, the United Nations General Assembly adopted Sustainable Development Goals (SDGs), to be met by the year 2030. These important goals range from poverty eradication and improvements in education and health to the protection of global assets, including the oceans and a stable climate. Unfortunately, neither the SDGs nor their background documents explain how governments should judge whether the development programs they undertake to meet the goals are sustainable.

Este trabalho objetiva analisar diversos aspectos do Direito Internacional Público em matéria de recursos hídricos de água doce superficiais e subterrâneos. Geração de energia, abastecimento, pesca, navegação, lazer, agricultura e indústria, são múltiplos os usos que os seres humanos fazem da água doce, mas antes disso a água é essencial para manutenção de todo e qualquer tipo de vida na Terra. São complexas e passíveis de várias análises as relações entre os Estados e as relações que se concretizam no interior dos Estados com objetivo de utilizar, controlar e preservar as fontes de água doce, a que se pretende fazer é uma análise jurídica, inserida no contexto político de expansão do capitalismo liberal. Pretende-se identificar e analisar normas jurídicas produzidas no âmbito internacional multilateral, considerando a sua forma, conteúdo e possíveis efeitos: na resolução de conflitos entre os Estados pelo controle e utilização da água doce, no estabelecimento de parâmetros para solução da crise ambiental e na superação dos problemas de acesso à água. Na primeira parte do trabalho, são identificadas as normas de Direito Internacional Público atinentes à matéria, descrevendo-se, primeiramente, a evolução histórica do Direito Internacional Fluvial até os estudos da doutrina de Direito Internacional e a Convenção de Nova York de 1997. O capítulo segundo objetiva apresentar o tema da água doce no contexto de surgimento do Direito Internacional do Meio Ambiente, de realização de conferências e criação de fóruns internacionais para a questão da água e do desenvolvimento de um direito humano à água. O capítulo terceiro propõe-se a ingressar na incipiente questão da regulamentação dos usos das águas subterrâneas, analisando os trabalhos da Comissão de Direito Internacional da Organização das Nações Unidas que culminaram com a adoção de uma Resolução sobre o Direito dos Aquíferos Transfronteiriços por parte da Assembleia Geral daquela organização. A segunda parte do trabalho objetiva analisar a aplicação das regras e princípios ensaiados nos textos de Direito Internacional aos casos concretos, confrontando-as com as soluções propostas em casos paradigmáticos de conflitos pela água, como o caso Gabcikovo-Nagymaros e o caso das Papeleras, envolvendo Argentina e Uruguai, ambos julgados pela Corte Internacional de Justiça. Na segunda parte do trabalho, também é analisado o caso do aquífero Guarani, um sistema de aquíferos interligados que se estende sob os subsolos de Argentina, Brasil, Paraguai e Uruguai, que em agosto de 2010 foi objeto de um tratado internacional assinado no âmbito do Mercosul. Por fim, a pesquisa objetiva desenvolver ideias e explicações para a existência (ou não) e a efetividade (ou a falta dela) das normas de Direito Internacional sobre recursos hídricos, considerando o conceito de soberania estatal que ora é o bode expiatório para a falta de assinaturas nos tratados ou de votos em declarações, ora é o próprio fundamento para a adoção de compromissos por parte dos Estados. Conclui-se tentando responder as seguintes questões: Existe Direito Internacional da água doce? São as normas de Direito Internacional efetivas? Para que servem essas normas de Direito Internacional, além da afirmação de sua própria existência como metas a serem atingidas?
