Restoration Work

Putting out of using large areas of agricultural lands in the central region over the past years has led to worsening the prospects of their purposed use, although the problem of the relevance of their restoration still remains. For many years the unused land was exposed to both natural exogenous processes such as erosion, suffusion, etc. and biological and chemical changes, usually for the worse for agriculture. There are considered elements of monitoring aimed at assessing the prospects or lack of perspectives of rehabilitation of degraded lands. An energy approach to assessing the state of slopes and soils located within these slopes is presented. The main factors of natural and anthropogenic character in assessing the prospects for land restoration are their steepness, excess relative to local bases of erosion other morphological characteristics of slopes which in general is reduced to an assessment of the energy provision of slopes and soils. So the higher the energy capacity of slopes – they are less promising for development, for soils – there is a reverse picture – the higher their energy reserves, the more promising is their use. Approaches to zoning the territory for monitoring from larger taxons of natural and anthropogenic genesis to the sites of special surveillance within which the prospects for rehabilitation of the agricultural land are evaluated. The most important factor is the material expediency of such actions, i.e. before starting the restoration work it is necessary to assess the profitability or loss of the proposed event. In cases of the material expediency it is feasible as further actions to include energy assessments of slopes and soils; zoning of the object according to the steepness and oriented characteristics of soil washout; and the possibility of obtaining agronomic and meteorological data on a timely basis. The result of the work is a forecast assessment of the prospects for restoring degraded land for the intended purpose using modern databases and WEB-systems.

The successful utilization of marginal and degraded lands for biomass and bioenergy production depends upon various factors such as climatic conditions, the adaptive traits of the tree species and their growth rate and respective belowground responses. The present study was undertaken to evaluate the growth performance of a bioenergy tree (Dalbergia sissoo Roxb.) grown in marginal and degraded land of the Mirzapur district of Uttar Pradesh, India and to analyze the effect of D. sissoo plantations on soil quality improvement over the study years. For this, a soil quality index (SQI) was developed based on principal component analysis (PCA) to understand the effect of D. sissoo plantations on belowground responses. PCA results showed that among the studied soil variables, bulk density (BD), moisture content (MC), microbial biomass carbon (MBC) and soil urease activity (SUA) are the key variables critically influencing the growth of D. sissoo. The SQI was found in an increasing order with the growth period of D. sissoo. (i.e., from 0.419 during the first year to 0.579 in the fourth year). A strong correlation was also observed between the growth attributes (diameter at breast height, R2 = 0.870; and plant height, R2 = 0.861) and the soil quality (p < 0.01). Therefore, the developed SQI can be used as key indicator for monitoring the restoration potential of D. sissoo growing in marginal and degraded lands and also for adopting suitable interventions to further improve soil quality for multipurpose land restoration programs, thereby attaining land degradation neutrality and United Nations Sustainable Development Goals.

Selection Of Species

The energy demand in Indonesia has increased significantly with its population growth, urbanization, and economic development. The growing concern of meeting energy demand while reducing dependency on fossil fuels has resulted in an increasing demand for renewable energy. As a country with a rich biomass base, bioenergy is now an important component of Indonesia’s energy agenda. However, a crucial problem in bioenergy production is the selection of species that can provide a sustainable supply of feedstock without having an impact on food security and the environment. In this context, we discuss the characteristics and benefits of using bamboo, a perennial grass, as a potential species for bioenergy feedstock in Indonesia. We describe the fuel characteristics of bamboo along with the possibility to align its cultivation, production, and usage with environmental and developmental agendas which makes it a suitable bioenergy crop in the country. In addition, its ability to grow on degraded lands, fast growth, long root system, and easy maintenance prove it as a powerful ally for the restoration of degraded land. We recommend in-depth research on the social, ecological, and economic feasibility of using this species for bioenergy production.

Environmental Concepts

&lt;p&gt;A goal of Land Degradation Neutrality by the year 2030 was agreed by the Rio+20 conference in 2012, and subsequently included in the Sustainable Development Goals. It dilutes earlier goals of unrestricted control of desertification, for example, by proposing that the rate of land degradation should be reduced and the rate of restoration of degraded land increased so they offset each other by 2030. As with many environmental concepts that have emerged in recent decades, Land Degradation Neutrality was proposed in the political arena, and scientific study is only now starting to evolve. Yet distinct positions are already forming within the scientific community, for example, on the feasibility of monitoring land degradation neutrality in dry areas when there are no reliable estimates for the rate of desertification, and on what constitutes land restoration in dry areas. Land degradation neutrality is also yet to be put in the wider context of environmental degradation as a whole, e.g. how does it relate to the forest degradation component of the Reducing Emissions from Deforestation and Degradation (REDD+) mechanism of the UN Framework Convention on Climate Change, and to degradation of biodiversity which the Convention on Biological Diversity is seeking to reduce. This session will allow scientists working in the field of land degradation neutrality to share their perspectives in this emerging field.&lt;/p&gt;

Remedial Actions

Abstract The destructive impact of land degradation on social and economic endeavours of the residents of certain urban areas of Abeokuta communities in Ogun State, Nigeria calls for remedial actions to restoring the affected land areas. This becomes essential in order to ensure safe inhabitation and enhanced socioeconomic engagements of the residents. Taken remedial actions in this regard included the use of sandbags, debris and wood logs, rubbles and stones, construction of contours and drainages. While each of these actions, in one way or the other, effectively improves the degraded land, it was concluded that the use of rubbles and stones, and drainage construction were sustainably durable for land restoration on the premise that these actions does not allow for water logging or flooding in of the study area. It was however recommended that these sustainable remedial actions should rather be pro-actively taken for prevention of land degradation than being taken as degraded land restoration actions basically because it is much cheaper to prevent environmental degradation than to have the degraded land restored.

The Impact

Derelict and degraded land destroys amenity, causes pollution and is a waste of productive land surface. Despite the worldwide activity to restore it there is an enormous backlog, which in England has increased since 1974. In the past much of this restoration was empirically based and not always successful. But natural ecosystems develop unaided on raw starting materials by natural ecological processes. A proper understanding of these has led to more reliable and inexpensive restoration techniques. At the same time we have come to realize that, because, at the start, the slate has been wiped clean, many different end points are possible. Derelict land is a challenge and opportunity for creative manipulation of our landscape. Yet what is achieved in practice is often pedestrian, unscientific and uneconomic. Often the simple treatments that would minimize the impact of industrial activity, and would set the restoration off early and in the right direction, are not carried out. Yet there are plenty of good examples of what can be done. It appears that once more we may be victims of the British failure in technology and imagination transfer. For this the fault seems to lie broadly, not only with planners, industrialists and government, for not always making sure something is done, but also with scientists, for not applying their ecological knowledge sufficiently to problems of hard practice.

Open Cast

To meet the growing demands of energy, continuous supply of coal is necessary because coal is the primary source of energy. About 70% of coal mining is being done by open cast methods which is most destructive activity and it severely damages the ecosystem. Reclamation of degraded land is therefore necessary after any mining activity. The biochemical parameters like Chlorophyll, carbohydrate and protein content of Psophocarpus tetragonolobus (Winged bean) studied here were considered as measure to test the suitability of Winged bean in various soil-OB dump compositions (P1 to P5). The findings revealed that biochemical property like chlorophyll and protein content of Winged bean was retained up to 1:1 soil-OB dump condition but after that it was decreased significantly whenever OB dump composition was increased. Chlorophyll content of the plant in P1 to P3 condition was 8.2, 8.17 and 8.02 mg/100 gm respectively but it was decreased significantly in P3 and P4 condition, i.e. 7.72 & 7.47 mg/100gm respectively. Carbohydrate content of the plant in P1 to P3 condition was 3.72, 3.7 and 3.61 gm/100 gm respectively but it again decreased significantly in P3 and P4 condition, i.e. 3.32 & 3.1 gm/100gm respectively. In spite of these findings, seeds of winged bean contained high protein and rest of the plant parts were also very important as food and fodder and this plant was able to grow on less water condition which made it suitable for the land restoration of degraded mining land both from ecological and socio-economic point of view.
