The Intergovernmental Panel on Climate Change established clear and solids conclusions on the 2013 report, it says that has been scientifically demonstrated with 95% of certainty, that human activities are the main cause of the global warming, observed since the middle of the XX century. The Orizaba Valley is a Mexican region, located at the geographic center of Veracruz State, having Orizaba City as the main demographic population surrounded by other municipalities, becoming the fourth metropolitan populated area of Veracruz State. This region has the third position on economic, historic and cultural relevance at Veracruz State, just after the Veracruz Port and Xalapa City. It was one of the main places with a vast economic growing during the Viceroyalty of the New Spain, being an obligatory passing route and resting place between Veracruz Port and Mexico City. This project estimates the magnitude of the Greenhouse Gas emissions coming from mobile sources at the Orizaba Valley. It includes the urban region of the municipalities of Ixtaczoquitlan, Orizaba, Río Blanco, Camerino de Mendoza and Nogales. The collected data was processed according to the Intergovernmental Panel on Climate Change methodology and it was possible to make the following projections: 1) One baseline scenario and 2) Three scenarios under hypothetical mitigation strategies that promise to achieve a reduction of GHG emission of 30 % from the year 2020 to 2050. Beyond this, also there is a significant reduction in fossil fuels consumption due to the efficient use of energy. All projections were made by using the Long-range Energy Alternatives Planning system software. In addition of the achievement on the GHG emissions reduction goal, it is possible to glimpse an economic recovery, if and only if, the decision makers of the governments decide to participate in the international trade of carbon market.

Although methane production from enteric fermentation in ruminants has been studied for many years, it is only recently that research has focused on reducing methane production in order to reduce greenhouse gas emissions. Many new and novel strategies are being researched, but this paper focuses on mitigation strategies that could currently be implemented from the knowledge already available.

REDD+ schemes are likely to be important components of climate change mitigation strategies for developing countries in a post-Kyoto framework. Many tropical forest countries have been preparing their REDD+ structures in anticipation of the requirements for REDD+ investment. Indonesia, as one of the main REDD+ supporters, is struggling to establish its REDD+ governance framework and REDD+ infrastructure while waiting for the REDD+ mechanism to be ready for implementation at the global level. Demonstration activities are being conducted and several policy documents and regulations have been released since 2007. However, some issues remain outstanding, including organization fragmentation, raising concerns as to whether a REDD+ scheme can be implemented to effectively reduce Indonesia’s greenhouse gas emissions. This paper examines Indonesia’s efforts in preparing the REDD+ scheme through evaluations of climate change and REDD+ policy products from various government organizations. Descriptive analysis involving observations on various climate change and REDD+ products is used to reveal complexities that exist within the relationship among government organizations. This paper exposes six lessons learned from Indonesia’s experience and concludes that reduction of organization fragmentation on REDD+ is to be the highest priority action for Indonesia in the short term. With a clear organization framework, REDD+ implementation will be easier to manage and potentially increase investor confidence in REDD+ projects in Indonesia.

<div><span>Agricultural nitrogen (N) inputs have grown massively over the last century, driving increases in crop yields, but also resulting in increased greenhouse-gas emissions and nutrient overloading of ecosystems. Of particular note is the increase in emissions of N<sub>2</sub></span><span>O, a greenhouse gas with 300 times the warming potential of CO<sub>2</sub></span><span>.  While the total global yearly N<sub>2</sub></span><span>O emissions can be easily deduced from atmospheric measurements, much less is known about the contribution of different cropping systems, and how increasing food demand will affect these emissions in the future. This knowledge is important for developing well-targeted mitigation strategies that reduce N<sub>2</sub></span><span>O emissions while increasing crop production. In order to help resolve this issue, we have simulated global croplands, one of the main beneficiaries of increased N inputs, using a process-based model that captures both crop growth and nitrogen and carbon cycling through the soil. This allows us to quantify total N<sub>2</sub>O emissions by crop type, identify hotspots and explore how a changing climate and increasing food demand are likely to impact future emissions. The idea is that this will aid in the search for agricultural management strategies that ensure food security while reducing the climate impact.</span></div><div> </div>
