Paddy farming has been affected by climate change phenomena such as high rainfall and long dry seasons which have caused plant and crop failure. To minimize the impact of climate change on their farming, paddy farmers undertake various strategies for dynamically adapting to climate change. This study aimed to analyze and assess the dynamics of the mitigation response by paddy farmers in West Java to minimize the impact of climate change. The object of research was paddy farmers in West Java. The research sample was selected using a multi-stage cluster random sampling technique to collect 300 respondents. Data analysis methods used descriptive statistics and multivariate analysis of variance (manova). The results showed that paddy farmers in West Java have dynamically mitigated climate change along with climate change over time. Types of climate change mitigation response applied by the majority of paddy farmers in West Java included planting shading trees, using energy saving technologies, cultivating organic agriculture, planting different crops instead of rice, changing farming to animal husbandry, migrating, looking for other income sources outside farming and renting/selling their land. Other mitigation responses that have rarely applied but interesting to explore were of shifting the planting and harvesting periods, selecting planting varieties, adapting plantation patterns and irrigation techniques. Farmers in Subang District who applied the most four types of climate change mitigation response earned higher income greater than those in Indramayu and Karawang.

Climate variability has been documented as being key to influencing human wellbeing across cities as it is linked to mortality and illness due to changes in the perceived weather cycle. Many studies have investigated the impact of summer temperature on human health and have proposed mitigation strategies for summer heat waves. However, sub-tropical cities are still experiencing winter temperature variations. Increasing winter perceived temperature through the decades may soon affect city wellbeing, due to a larger temperature change between normal winter days and extreme cold events, which may cause higher health risk due to lack of adaptation and self-preparedness. Therefore, winter perceived temperature should also be considered and integrated in urban sustainable planning. This study has integrated the increasing winter perceived temperature as a factor for developing spatiotemporal protocols for mitigating the adverse impact of climate change. Land surface temperature (LST) derived from satellite images and building data extracted from aerial photographs were used to simulate the adjusted wind chill equivalent temperature (AWCET) particularly for sub-tropical scenarios between 1990 and 2010 of the Kowloon Peninsula, Hong Kong. Compared with perceived temperature based on the representative station located at the headquarters of the Hong Kong Observatory, the temperature of half the study area in the Kowloon Peninsula has raised by 1.5 °C. The areas with less green space and less public open space in 2010 show higher relative temperatures. Socioeconomically deprived areas (e.g., areas with lower median monthly income) may suffer more from this scenario, but not all types of socioeconomic disparities are associated with poor sustainable planning. Based on our results and the “no-one left behind” guideline from the United Nations, climate change mitigation should be conducted by targeting socioeconomic neighborhoods more than just aging communities.

The paper performed comparative assessment of greenhouse gas (GHG) emission trends and climate change mitigation policies in the fuel combustion sector of selected EU member states with similar economic development levels and historical pasts, and implementing main EU energy and climate change mitigation policies, having achieved different success in GHG emission reduction. The impact of climate change mitigation policies on GHG emission reduction was assessed based on analysis of countries’ reports to UNFCCC by identifying the key areas of GHG emission reduction, their GHG emission reduction potential, and the driving forces behind them. The study revealed that climate change mitigation policies that have been implemented so far in Bulgaria are less efficient than in Lithuania, as Bulgaria places priorities not on energy efficiency improvement and penetration of renewable energy sources, but on switching from coal to natural gas. The policy implications for strengthening GHG emissions reduction efforts are provided based on analysis conducted.

<p>Climate change represents a key challenge to the sustainability of global ecosystems and human prosperity in the twenty-first century. The impacts of climate change combined with natural climate variability are predominantly adverse, and often exacerbate other environmental challenges such as degradation of ecosystems, loss of biodiversity, and air, water and land pollution. Besides, rapid industrialization and increasing adaption of agrochemical based crop production practices since green revolution have considerably increased the heavy metal contaminations in the environment.</p><p>Assessing the impacts of climate change on our planet and addressing risks and opportunities is essential for taking decisions that will remain robust under future conditions, when many climate change impacts are expected to become more significant.</p><p>Here, we established a review survey to assess the impact of biochar amendment and agroforstry system on CO<sub>2</sub> sequestration and methaloid remediation.</p><p>Our data base showed that Agroforestry-based solutions for carbon dioxide capture and sequestration for climate change mitigation and adaptation in long-term is more practical and realistic options for a sustainable ecosystem and decreasing negative effect of climate change. This was more supported in arid and semi-arid regions as well as area with saline and alkaline soil (20%).</p><p>From a soil remediation standpoint, the general trend has been shifting from reduction of the total concentration to reduction of the physic-chemically and/or biologically available fractions of metals. This regulatory shift represents a tremendous saving in remediation cost. While metals are not degradable, their speciation and binding with soil through biochar amending reduced their solubility, mobility, and bioavailability. While agroforestry showed high efficiency in C sequestration (32%), biochar amendment raveled significant mitigation in heavymetals bioavailability (42%). However, studies which coupled both approaches are limited. Thus, we conclude that combined Agroforestry and biochar amendment regulates C sequestration and metalloids remediation more efficiently.</p>

Bhumibol Dam is the largest dam in the central region of Thailand and it serves as an important water resource. The dam’s operation relies on reservoir operating rules that were developed on the basis of the relationships among rainfall-inflow, water balance, and downstream water demand. However, due to climate change, changing rainfall variability is expected to render the reliability of the rule curves insecure. Therefore, this study investigated the impact of climate change on the reliability of the current reservoir operation rules of Bhumibol Dam. The future scenarios from 2000 to 2099 are based on EC-EARTH under RCP4.5 and RCP8.5 scenarios downscaled by RegCM4. MIKE11 HD was developed for the inflow simulation. The model generates the inflow well (R2=0.70). Generally, the trend of increasing inflow amounts is expected to continue in the dry seasons from 2000-2099, while large fluctuations of inflow are expected to be found in the wet seasons, reflecting high uncertainties. In the case of standard deviations, a larger deviation is predicted under the RCP8.5 scenario. For the reservoir’s operation in a climate change study, standard operating procedures were applied using historical release records to estimate daily reservoir release needed to serve downstream water demand in the future. It can be concluded that there is high risk of current reservoir operating rules towards the operation reliability under RCP4.5 (80% reliability), but the risk is lower under RCP8.5 (87% reliability) due to increased inflow amounts. The unmanageability occurs in the wet season, cautioning the need to redesign the rules.

Agroforestry is land-use systems and technologies where woody perennials are deliberately used on equivalent land management units as crops and/or animals. Its systems combine tree growing with the assembly of different crops or animals. Hence, developing positive ecological and economic interactions between components, agroforestry systems aim to produce a variety of environmental, economic and social advantages to farming communities. It plays a major role in soil conservation and global climate change mitigation particularly due to its tree component. Trees control soil degradation through their roots and accumulate greenhouse emission (GHG) in their biomass. What is more, it conjointly helps in global climate change adaptation. It’s a long-time undeniable fact that despite our gift effort at global climate change mitigation (GHG reduction), there is an additional pressing ought to address the impact of global climate change (adaptation). Peoples ought to be acutely aware regarding the scope and advantages of agroforestry and that they ought to participate in the implementation and development of agroforestry within the country. Thus, this paper reviews different analysis findings on the opportunities and challenges for scaling up agroforestry practices. Therefore, the agroforestry system is economically and ecologically sound practices with an improvement of overall farm productivity, soil enrichment through litterfall, maintaining environmental services like international global climate change mitigation (carbon sequestration), phytoremediation, watershed protection and biodiversity conservation.
