Abstract Hydropower is the second largest conventional energy resource in China. It is a renewable energy with mature technology, flexible operation, cleanliness and low carbon. A hydropower project has flood control, a water supply, navigation, irrigation and other comprehensive utilization functions. The new era in China is guided by the new energy-security strategy of ‘four revolutions and one cooperation’ and the new development concept of ‘innovation, coordination, green development, openness and sharing’. According to the dual nature of water and electricity, this paper deepens the basic understanding of hydropower from the experience of the world, the difficult problems of hydropower in China and the long-term development of hydropower enterprises. The future direction of hydropower development is explored from the following aspects: high-quality development of follow-up hydropower projects, innovative utilization of existing hydropower value, creative pursuit of hydropower-benefit growth and high-level promotion of hydropower international cooperation.

Water development projects to manage the country's water reserves for flood control, agriculture and energy production have always been part of the Mexican federal government's politics. In southeastern Mexico these projects have been proposed to promote ‘modernization’ in a region characterized by a high level of social marginalization. A prime example of these projects is the Plan Chontalpa (referred to from here on as the Plan), a large-scale, state-led development initiative proposed by the federal government to manage the Grijalva River basin and promote industrial agricultural production and social development in Tabasco (Figure 1). Plan Chontalpa was meant to be a model for development in humid tropical regions. However, it fell short of its original goals of promoting hydroelectricity generation and agricultural production. Plan Chontalpa has been changing through the years and most recently is promoting a "green" development following the guidelines of the Puebla-Panama Plan, a regional development initiative impacting all Mexican states located south of Puebla and all the Central American countries up to Panama.

Abstract Green recovery has been highly advocated as a promising strategy to balance climate actions and economic reset after COVID-19. However, the potential inequality risk associated with the green recovery hasn’t been fully assessed. Here, enabled by an extended adaptive regional input-output (E-ARIO) model, we quantify the short-term impacts of COVID and various recovery packages on labor demand and income equality. The findings reveal that in the pandemic, low- and medium-income labor suffered more income decrease (by 36%) than those with high-level income (by 24%), leading to a 24% increase of income inequality at the global level (measured by the Oshima coefficient). The high-income labor benefits more from a low-carbon pathway to economic recovery, which further exacerbates the income inequality across the world by 3 ~ 5% compared to those in a traditional, carbon-intensive recovery scenario. The findings reveal the tradeoffs between income equality and green development and underscore the urgency of just transition alongside green recovery.

This paper concerns the necessity of ecosystem protection and energy efficiency rating development. The article analyzes the experience of the non-commercial Environmental and Energy Rating Agency (Interfax-ERA) ratings concerning the environmental assessment of Russian regions and the transfer of successful knowledge for evaluating 31 Chinese provinces. The theoretical base, quantitative and qualitative characteristics of the energy-resource efficiency (ERE) rating, technological efficiency (TE), and ecosystem impact (EI) ratings are proposed based on the system methodology, developed within the framework of the UN Sustainable Development Goals (SDGs). The primary study objective is to determine whether the Interfax-ERA rating methodology and considered criteria could be applied in China to assess the provinces’ environmental, technological, and energy efficiency. The research highlights the importance of multifunctional tools for developing experiences and sharing methodological experiences across countries. The study efficiently emphasizes provinces with a high level of energy efficiency and technological innovations as well as the provinces with the deficient level of eco-oriented economy policy. The results show two types of systematic deviations—significantly high-level impact on the ecosystem in the Chinese provinces and considerably high levels of energy and resource efficiency in capitals and business centers.

In the developing countries populations, which are already vulnerable and food insecure, are likely to be the most seriously affected by the effects of climate change, e.g. yield decreases and price increases for the most important agricultural crops. The IPCC’s Fourth Assessment Report for Africa describes a trend of warming at a rate faster than the global average and increasing aridity: in many parts of Africa, it seems that warmer climates and changes in precipitation will destabilise agricultural production and aggravates food security. The present work concerns the vegetables cultivation in the Parakou region in Benin, where agriculture employs approximately 70% of the active population and contributes to 36% of the Gross Domestic Product and 88% of export earnings. However, the agricultural sector has been regarded as unproductive with low adaptation capacities because of structural factors (e.g. high level of poverty among rural populations, weak mechanization and intensification of production modes), but also because of natural constraints (e.g. poor management of water and soils, leading to soil degradation). Considering the aridity, the low carbon content and the reduced level of nutrients available in the soil, the use of an hydroponic module has been hypothesised. In this way sufficient yields of the crops may be assured and no agricultural machines will be needed for the tillage operations. In addition, the nutrients can be added to the growing solution using residual materials as poultry manure, ashes and green wastes. In order to verify if some construction or maintenance problems can occur and if a growing solution can be easily obtained using agricultural wastes, some tests have been carried out. Moreover laboratory analyses have been done for different solutions that may be adopted with different shares of water, poultry manure, ashes and green wastes. The tests have indicated that the hydroponic module could be used in Benin without incurring in technical problems and that a growing solution containing poultry manure, ashes and green wastes can supply to the crops a significant amount of nutrients.

Recovery And Reuse

Climate change caused by greenhouse gases is receiving worldwide attention. CO2 (carbon dioxide) emission accounts for 80% of greenhouse gas emissions. The current measures against emission of CO2 are mainly control of emissions, sequestration and fixation, but CO2 emission decreased by only 1.6% in Europe during the past decade. CO2 recovery and reuse may offer new options for the greenhouse gas strategy. CO2 recovery technology such as the amine process is economically and technically feasible for industrial-scale application, and the recovered CO2 can be utilized for energy production, development of new energy resources, agriculture, etc. Recycling of CO2 on a large scale is discussed in this paper.
