Biomass Resources

Abstract In the future, the world is expected to rely increasingly on renewable biomass resources for food, fodder, fibre and fuel. The sustainability of this transition to bioeconomy for our water systems depends to a large extent on how we manage our land resources. Changes in land use together with climate change will affect water quantity and quality, which again will have implications for the ecosystem services provided by water resources. These are the main topics of this Ambio special issue on “Environmental effects of a green bio-economy”. This paper offers a summary of the eleven papers included in this issue and, at the same time, outlines an approach to quantify and mitigate the impacts of bioeconomy on water resources and their ecosystem services, with indications of useful tools and knowledge needs.

Extensive urbanization around the world has caused a great loss of farmland, which significantly impacts the ecosystem services provided by farmland. This study investigated the farmland loss due to urbanization in the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) of China from 1980 to 2018 based on multiperiod datasets from the Land Use and Land Cover of China databases. Then, we calculated ecosystem service values (ESVs) of farmland using valuation methods to estimate the ecosystem service variations caused by urbanization in the study area. The results showed that 3711.3 km2 of farmland disappeared because of urbanization, and paddy fields suffered much higher losses than dry farmland. Most of the farmland was converted to urban residential land from 1980 to 2018. In the past 38 years, the ESV of farmland decreased by 5036.7 million yuan due to urbanization, with the highest loss of 2177.5 million yuan from 2000–2010. The hydrological regulation, food production and gas regulation of farmland decreased the most due to urbanization. The top five cities that had the largest total ESV loss of farmland caused by urbanization were Guangzhou, Dongguan, Foshan, Shenzhen and Huizhou. This study revealed that urbanization has increasingly become the dominant reason for farmland loss in the GBA. Our study suggests that governments should increase the construction of ecological cities and attractive countryside to protect farmland and improve the regional ESV.

Past Land Use

The evaluation of the impacts of land-use change on the water resources has been, many times, limited by the knowledge of past land use conditions. Most publications on this field present only a vague description of the past land use, which is usually insufficient for more comprehensive studies. This study presents the first reconstruction of the historical land use patterns in Amazonia, that includes both croplands and pasturelands, for the period 1940-1995. During this period, Amazonia experienced the fastest rates of land use change in the world, growing 4-fold from 193,269 km2 in 1940 to 724,899 km2 in 1995. This reconstruction is based on a merging of satellite imagery and census data, and provides a 5'x5' yearly dataset of land use in three different categories (cropland, natural pastureland and planted pastureland) for Amazonia. This dataset will be an important step towards understanding the impacts of changes in land use on the water resources in Amazonia.

Abstract Water resources modeling can provide valuable information to planners. In this respect, water yield is an ecosystem service with significant roles in the sustainability of societies and ecosystems. The present study aimed to model the supply and demand of water resources and identify their scarcity and stress in the Sirvan river basin. For this purpose, we employed the ecosystem services concept as new thinking in earth sciences and using soil, climate, and land use data. Firstly, the Landsat satellite images of 2019 were prepared after different corrections, and the land use map was produced. Then, precipitation, evapotranspiration, root restricting layer depth, and evapotranspiration coefficients of the land uses were prepared and modeled in InVEST 3.8.9 software environment. The findings indicated that the water yield in this river basin is 5,381 million m3, with sub-basins 5, 11, and 1 having the highest water yield per year and sub-basin 2 having the lowest water yield. Moreover, sub-basins 5 and 11 had the highest water consumption. Based on the estimated water scarcity and stress index, sub-basin 8 has experienced water scarcity and sub-basin 4 water stress. We conclude that applying the InVEST Water Yield model to assess water resource status at the basin and sub-basins level can provide suitable results for planning.

History Of

The IUPAC-sponsored 13th International Biotechnology Symposium (IBS) and Exhibition was held successfully from 12 to 17 October 2008 in Dalian, China, with about 2500 participants, including 50 % international delegates from about 80 countries. More details of the conference are available in Chemistry International31 (3), 28-29 (2009).The theme of the conference was "Biotechnology for the sustainability of human society", through which all key biotechnology topics closely related to the better living of human beings were discussed. Examples included biopharmaceuticals and advanced diagnostic and therapeutic technologies, green biotechnology for the improvement of agricultural production yield and efficiency, industrial biotechnology for the production of biofuels and bio-based chemicals from renewable biomass resources as alternatives to fossil-based feedstocks, bioremediation of pollutants and contaminants to save the continuously deteriorating eco-environment, and biosafety and biosecurity associated with the progress of advanced biotechnology.With the sponsorships of international and domestic academic publishers, several special issues have been published for the conference, reporting or reviewing the frontiers of modern biotechnology with specific focus. It has been recognized that chemistry is the fundamental discipline to drive the progress of biotechnology R&D since its inception. This importance was highlighted by over half a century history of the IBS series dating back to as early as 1960 when the first IBS was initiated under the auspices of IUPAC in Rome, Italy, and continuously increased numbers of participants trained with chemistry backgrounds, which gives us, as the conference organizers, the pleasure of publishing this special issue in Pure and Applied Chemistry with a theme: "Building the bridge between chemistry and biotechnology".Invitations were issued to 42 Symposium presenters whose contributions were deemed to be directly relevant to the chosen theme, and resulted in this collection comprising 29 papers devoted to aspects of research progress in the interdisciplinary area of chemistry and biotechnology. Although the publication comes later than expected, we believe that its objective to highlight the critical role of chemistry in the development of biotechnology is never out of date. As the guest editors of this special issue, we are very pleased to share this publication with colleagues around the world, and we are also grateful to IUPAC, the authors, and the referees for all of their contributions toward this record of an important interdisciplinary feature of the IBS program.F.

If our current way of life is to be kept sustainable, particular attention must be paid to the management of the world around us – including our environmental conditions, natural resources and assets, and particularly the available water resources – and to the protection of natural elements that are, for whatever reason, of crucial importance for all of us. The aims and methods of the necessary protection are, however, not always compatible with farming activities and forms of land use that have been practiced, in some cases, for centuries. This article describes some of the incompatibilities and conflicts between various forms of farming and the relatively new domestic nature conservation activities, with a focus on Hungary’s nature conservation areas and particularly its wetland ecosystems. This is followed by a discussion of problems associated with such conflicts and proposals for resolving them.

Percent Area

The country’s geographical area is 79.61 million hectares (mha), excluding the Northern Areas of Pakistan. Out of this, only 72 percent area has been reported indicating a major limitation that 28 percent area is not yet surveyed for land use classification. The reported area is further classified into four major classes: (a) forest area of 4.02 mha; (b) area not available for cultivation of 22.88 mha; (c) culturable waste of 8.12 mha; and (d) cultivated area of 22.05 mha. Out of the reported area, around 8.1 mha are available for future agriculture and other uses, if water is made available. If rest of the area (28 percent) is also surveyed then one can have better picture of country’s land resources (Table 1).
