Soil emission of CO2 is closely linked to soil degradation, decrease in soil organic carbon (SOC) content and decline in soil quality. Enhancing soil quality through adoption of best management practices (BMPs) and soil restoration can increase SOC content and soil productivity, and partially mitigate the greenhouse effect. The C sequestration potential through judicious management of world cropland includes 0.08–0.12 Pg/yr by erosion control, 0.02–0.03 Pg/yr by restoration of severely degraded soils, 0.02–0.04 Pg/yr by reclamation of salt-affected soils, 0.15–0.175 Pg/yr by adoption of conservation tillage and crop residue management, 0.18–0.24 Pg/yr by adoption of improved cropping system and 0.30–0.40 Pg/yr as C offset through biofuel production. The total C sequestration potential of the world cropland is about 0.75–1.0 Pg/yr or about 50% of annual emission of 1.6–1.8 Pg by deforestation and other agricultural activities. This finite soil-C sink could be filled over a 20 to 50-year period, during which energy related emission reductions gradually take effect at global scale. Improving soil quality is a win–win strategy, while increasing productivity it also improves environment and partially mitigates the greenhouse effect. Intensification of farming and increasing biomass production can lead to increased sequestration of C in soils, and to partly meet commitments under the Kyoto Protocol at national and global scales. Global reduction in C emission may have to be substantial if the atmospheric concentration of CO2 is to be stabilized at 550 ppmv. However, realization of this potential would require developing channels of communication between scientists and land managers and policy makers, and providing economic incentives.

Climatic Change

Large, irreversible changes in climate may have a major effect on the economies of the world. The social costs of climate change will vary dramatically from country to country. This landmark assessment from Working Group III of the IPCC addresses the costs of climate change, both in terms of society and equity issues, and the economic burden of combating adverse climate change. The editors assess the response options, the applicability of cost-benefit analysis to climate change, and the costs faced by the many countries committed to limit greenhouse gas emissions by the year 2000. This exhaustive analysis will be invaluable for the international community of policy makers concerned with the consequences of climate change.

The United Nations Environment Program and the World Meterological Organization set up the Intergovernmental Panel on Climate Change (IPCC) in 1988 to provide an authoritative international consensus of scientific opinion on climate change. This report, prepared by IPCC Working Groups I and II, reviews the latest scientific evidence on the following key topics: radiative forcing of climate change; the latest values of global warming potential (used to compare the potential effect on future climate of different anthropogenic factors); the stabilization of greenhouse gas concentrations in the atmosphere; and an evaluation of scenarios of future greenhouse gas emissions. Researchers in climatology and environmental science, as well as environmental and science policy, will benefit from this book.

... In contrast, afforestation of bare areas enhances soil and ecosystem protection . According to Bruce et al. (1999), deforestation and soil erosion lead to the release of approximately 1.7 and 0.1 PgCyr⁻¹ of carbon emissions into the atmosphere, respectively. However, increasing forest cover, rehabilitating degraded forests, implementing sustainable land management practices (Lal, 2001), and strengthening environmental protection measures (Wali et al., 1999;Kara et al., 2016;Babur et al., 2021a) can significantly mitigate global CO₂ emissions (Post & Kwon, 2000). ...

... Although climate change is considered the most challenging issue that human social, political, and economic systems have ever faced, the social sciences have limited scientific discourse on the matter due to scientific constitutions, where the social is separated from the natural [4][5][6][7]. Since the 1960s, environmental degradation has been highlighted as a major problem, which was at that time connected to a relatively radical proposition: that society should behave with intergenerational care to protect the interests of the future [8][9][10][11]. While social sciences have played a minor role in the matter to date, there is now a growing awareness of the fact that climate change is strongly related to human choices as far as development and lifestyle decisions are concerned [5][6][7]. The Global Climate Observing System (GCOS) also identifies a set of key global climate indicators beyond those of temperature [1,2,5]. ...

... The parallels to the search for possible responses to global climate change are obvious in spite of the varigated terminology: (1) prevention of further increases in the atmospheric concentration of greenhouse gases, (2) mitigation of impacts (bounding of first order environmental changes), and (3) adaptation to the impacts (higher order responses to impacts) (Bruce, Lee, and Haites, 1996;Houghton et al., 1996;Watson et al., 1996). Understanding the causal linkages among the social and physical processes that interact to produce a hazard on the one hand, and illuminating the causal linkages across scales from the global to the local on the other, are parallel challenges that need to be addressed in order to adequately prepare for the management of climate change-related environmental hazards (e.g., Cash, 1997;Global Environmental Assessment Project, 1997;Kotlyakov et al., 1988;Turner et al., 1990). ...

... It mainly comprises of approximately 45-60% CH 4 and 40-60% CO 2 (Tchobanoglous et al., 1993). CH 4 and CO 2 are the main and the most affecting greenhouse gases to the global warming problem due to their ability to absorb solar energy and maintain it near earth's crust for years (Houghton and Callander, 1992). In sanitary landfills equipped with gas recovery system, LFG is collected and utilized mainly for energy production due to CH 4 existence. ...

... While the IPCC had its own set schedule for producing comprehensive assessment reports, the production of special reports was often driven by immediate political needs and therefore their schedule was determined largely by the rhythms of international negotiations at the UNFCCC. This was particularly evident in the undertaking of the IPCC's first special report-the Special Report to the UNFCCC COP1 (IPCC 1994a;1994b). Unlike any other special report, this first special report is not a single document but consists of two separate reports and contains three different parts, each of which was prepared and approved independently by the three Working Groups (WGs). 5 The story behind the birth of this first special report was that fast-evolving politics in the early 1990s necessitated the readjustment of the work schedule of IPCC assessment (Bolin 2007;Provost 2019). ...

... The conversion of organic material to soil organic material in the leftovers and the storage of SOC depend on careful nutrient management. Low soil organic content results from low input and subsistence agriculture techniques; this may be improved by adding organic amendments that enhance nutrient recycling (Lal and Bruce 1999). ...
