The study used remote sensing data to investigate the state of vegetation cover along the northern fringes of the park and an adjacent communal grazing area to determine differences in plant based resource endowments between the two areas. The study also involved the discriminant analysis of survey responses from park officials and local communities regarding perceptions about the environmental impacts of Acacia mearnsii invasion, as well as how the species spreads and how the species can be controlled. The objective of the study was to assess park-community conflicts arising from initiatives to limit community access to park resources on the justification of the need to prevent the invasion of the park by A. mearnsii. The study concludes that even though uncontrolled movement of people and livestock creates the obvious danger of invasion of the park by the species, the extent to which the species is viewed as an environmental threat depends on the “worldviews” of the stakeholders, the bridging of which can only be achieved through negotiation, environmental awareness and education campaigns and provision of training in conflict resolution to the belligerents.","PeriodicalId":16194,"journal":{"name":"Journal of Integrative Environmental Sciences","volume":"12 1","pages":"37 - 54"},"PeriodicalIF":2.4,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78160321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Farmers are the hardest hit as they have to continuously respond to climatic variations. In order to understand farmers' perceptions of climate change and its impacts, and to identify adaptation needs, focus group discussions and semi-structured questionnaire surveys were carried out at the end of the south-west monsoon season in 2012 (Kharif cropping season in India). This helped to gather their immediate responses soon after the poor performance of south-west monsoon 2012. Khariff cultivation is locally known as ‘Kuruvai’ and is always under the influence of the south-west monsoon rainfall. Farmers' have perceived climate variability, and identified increasing temperature, delayed onset, intermittent dry spells and decreasing soil moisture as the critical factors affecting their cultivation. Some of them have started to adapt to these changes by cultivating only short-duration crops such as pulses, vegetables and flowers especially jasmine, but there is also a trend to put more land under fallow and abandoning the major cereal production. This study reveals that the farmers' perceptions are in accordance with the real trends analysis done on meteorological variables using Mann–Kendall test and Sens's slope estimator test, but not exactly matches with rainfall. Farmers have indicated their specific adaptation needs, a number of which could be incorporated into site-specific adaption strategies and policies.","PeriodicalId":16194,"journal":{"name":"Journal of Integrative Environmental Sciences","volume":"106 1","pages":"1 - 18"},"PeriodicalIF":2.4,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79293119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although India still has a low per capita carbon level, due to its large population and growing economy, its share of global greenhouse gas emissions is rising. India is, thus, a particularly important country to examine in relation to climate change. This article investigates one particular aspect of India’s climate policy: the role its cities play within its multi-tiered climate governance system. India is still a predominantly agricultural society with two-thirds of its population (about 850 million people) living in rural areas. Urbanization is, however, progressing; estimates are that India will add over 400 million urban dwellers between 2014 and 2050 bringing the urban population to over 800 million (United Nations, Department of Economic and Social Affairs, Population Division 2014). This article aims to shed light on the challenges, capabilities and limitations of India’s urban areas to deal with mitigating climate change. It complements the other articles in this special issue which focus on subnational state and provincial level climate policy. It takes as its starting point the academic multi-level climate governance debate and also looks at the role the co-benefit concept plays at the urban level. The article highlights key actors, drivers, and institutions of city climate action and considers how local climate policy and programs are enabled and constrained by India’s federal political system. Finally, the role of international city partnerships in supporting climate activities is considered. To explore the conditions shaping climate action in India’s cities this article builds on a literature review and discussions held at an Indian-German expert meeting which took place in Bangalore in April 2015.","PeriodicalId":16194,"journal":{"name":"Journal of Integrative Environmental Sciences","volume":"129 1","pages":"55 - 66"},"PeriodicalIF":2.4,"publicationDate":"2016-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89029060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results from the DSSAT model show that during the main and off growing seasons, increase in temperature and changes rainfall pattern can be expected to reduce the rice yield by 12 and 31.3%, respectively, until the year 2030. Based on the system dynamics’ results, the reduction in rice yield was expected to reduce farmers’ gross income and the rice self-sufficiency level of the country.

A two-year field experiment was conducted at Huizhou, Guangdong province, South China, to identify from among nine cultivars those cultivars with high-yield potential and lower yield-scaled methane emissions (YSMEs). Methane emissions were measured using the static chamber – gas chromatograph method. Results indicate that the cultivars Qihuazhan (QH), Yexianzhan 8 (YX8) and Yue’erzhan (YE) provide higher rice grain yield (8.69%) with lower YSME (30.27%) compared to the other six cultivars (Yexianzhan 6, Yuejingsimiao, Hefengzhan, Huangsizhan, Huangruanzhan and Huangxiuzhan) (p < 0.05). In particular, QH has the highest yield potential (6777 kg ha−1) and lowest methane emission intensity (0.36 kg kg−1 yield) capacity. Methane emissions from the double rice field was found to be significantly (p < 0.05) and positively correlated with tiller number, culm biomass and soil organic matter, dissolved soil organic carbon and total carbon content, but negatively correlated (p < 0.05) with rice harvest index (HI), and root and panicle biomass, suggesting that organic source strength provides the substrate of methane production while the oxidation potential in the rhizosphere and the methane transport capacity of rice roots and culm dominate the emissions of methane from soil to the atmosphere. Multivariate decision regression tree (DRT) analysis showed a significant class difference between QH, YX8 and YE with the other six cultivars. These three cultivars are suitable for promotion of low carbon agriculture in South China. DRT analysis also successfully illustrated a potential way to identify rice varieties for low YSME by decisive parameters of tiller number (<15), HI (>0.43) and nitrogen assimilation of leaves (<40). These findings suggest that optimization of rice cultivars may represent an effective way to address both food demand and climate change concerns by improving rice yields while simultaneously minimizing the impact of climate change per unit yield.","PeriodicalId":16194,"journal":{"name":"Journal of Integrative Environmental Sciences","volume":"68 1","pages":"47 - 66"},"PeriodicalIF":2.4,"publicationDate":"2015-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86091234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While agriculture is a substantial source of emissions, it is also generally considered to be a potential source of cost-effective non-CO2 GHG abatement. Previous “bottom-up” analyses provided marginal abatement cost (MAC) curves for use in modeling these options within economy-wide and global mitigation analyses. In this paper, we utilize updated economic and biophysical data and models developed by the US Environmental Protection Agency (EPA) to investigate regional mitigation potential for major sources of agricultural GHG emissions. In addition, we explore mitigation potential available at costs at or below the estimated benefits of mitigation, as represented by the social cost of carbon. Key enhancements over previous regional assessments include incorporation of additional mitigation options, updated baseline emissions projections, greater spatial disaggregation, and development of MAC curves through 2030. For croplands and rice cultivation, biophysical, process-based models (DAYCENT and DNDC) are used to simulate yields and net GHG emissions under baseline and mitigation scenarios while the livestock sector is modeled by applying key mitigation options to baselines compiled by EPA. MAC curves are generated accounting for net GHG reductions, yield effects, livestock productivity effects, commodity prices, labor requirements, and capital costs where appropriate. MAC curves are developed at the regional level and reveal large potential for non-CO2 GHG mitigation at low carbon prices, especially in Asia.","PeriodicalId":16194,"journal":{"name":"Journal of Integrative Environmental Sciences","volume":"26 1","pages":"105 - 87"},"PeriodicalIF":2.4,"publicationDate":"2015-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86646177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The report, Global Mitigation of Non-CO2 Greenhouse Gases: 2010–2030 provides a comprehensive global analysis and resulting data-set of marginal abatement cost curves that illustrate the abatement potential of non-CO2 GHGs by sector and by region. The basic methodology – a bottom-up, engineering cost approach – builds on the baseline non-CO2 emissions projections published by EPA, applying abatement options to the emissions baseline in each sector. The results of the analysis are MAC curves that reflect aggregated breakeven prices for implementing abatement options in a given sector and region. Among the key findings of the report is that significant, cost-effective abatement exists from non-CO2 sources with abatement options that are available today. Without a price signal (i.e. at $0/tCO2e), the global abatement potential is greater than 1800 million metric tons of CO2 equivalent. Globally, the energy and agriculture sectors have the greatest potential for abatement. Among the non-CO2 GHGs, methane has the largest abatement potential.

Pulles","doi":"10.1080/1943815X.2015.1118131","DOIUrl":"https://doi.org/10.1080/1943815X.2015.1118131","url":null,"abstract":"The importance of non-CO2 greenhouse gases The IPCC Synthesis Report states that reducing emissions of non-CO2 agents can be an important element of global mitigation strategies. The non-CO2 greenhouse gas symposium (NCCG7) shows how this could be possible. Global warming is caused by several greenhouse gases. The focus of science and policy is mostly on carbon dioxide (CO2). But there are more greenhouse gases. Non-CO2 greenhouse gases are important contributors to radiative forcing of the atmosphere and include methane (CH4), fluorocarbons and SF6 and nitrous oxide (N2O). The effects of black carbon (BC) and the so-called indirect gases, contributing to tropospheric ozone formation and aerosols add to this list. The latest IPCC Synthesis Report states that the human influence on the climate system is clear and growing (IPCC 2014). It also states that implementing stringent mitigations activities can ensure that the impacts of climate change remain within a manageable range, creating a brighter and more sustainable future. To keep a good chance of staying below 2 °C our emissions should drop by 40–70% globally between 2010 and 2050, falling to zero or below by 2100. The chair of IPCC (RK Pachauri) added to this that “we have that opportunity, and the choice is in our hand” (press release, 2 November 2014). Ambitious emission reduction is possible, but the window for action is rapidly closing. Leo Meyer (PBL, The Netherlands and IPCC Technical Support Unit) indicates that 65% of our carbon budget compatible with a 2° warming goal is already used (Figure 1). This implies that if we want to limit global warming to 2°, some fossil fuels will have to stay underground (Pulles 2015). The economic consequences of such measure moderate. Business as usual scenarios typically assume an economic growth of a few percent per year. In scenarios consistent with a 2° warming this economic growth is hardly affected (Meyer 2014). Reducing emissions of non-CO2 agents can be an important element of mitigation strategies. However, the IPCC Synthesis report is not very explicit about how to achieve this. Emissions of non-CO2 gases (methane, nitrous oxide and fluorinated gases) contributed by about 27% to the anthropogenic global emissions of Kyoto gases in 2010. The week following the publication of the IPCC Synthesis Report, the 7th non-CO2 Greenhouse Gas Symposium (NCGG7) was organized. More than 200 scientists from all over the world presented their work. Following are some highlights from the conference. Several illustrative 2° scenarios exist according to Niklas Höhne (New Climate Institute; 2014). These typically assume that fossil CO2 emissions are reduced to zero and that CO2 from forestry is becoming negative (indicating a carbon sink). Non-CO2 greenhouse gases are typically stabilizing or slightly reducing, assuming that it will be difficult to reduce emissions of CH4 and N2O from food production. Nevertheless, about half of the avoided warming in a recently","PeriodicalId":16194,"journal":{"name":"Journal of Integrative Environmental Sciences","volume":"129 44 1","pages":"1 - 4"},"PeriodicalIF":2.4,"publicationDate":"2015-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88932186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon dioxide (CO2) is typically emitted during fuel combustion in production processes. In addition, methane (CH4) and nitrous oxide (N2O) are emitted during palm oil production. We quantified current and future emissions of CH4 and N2O based on future projections for palm oil production in Thailand. Our analysis distinguishes between emissions from oil palm plantations and palm oil processing mills. Our study shows that nitrogen fertilizers are the main source of N2O emissions, while CH4 is emitted mainly from inappropriate management of empty fruit bunches and wastewater management.
