Abstract:
In addressing the current climate crisis, research into how past societies have coped with risk and ecological uncertainty can provide old solutions to new problems. Here, we examine how human niche construction can be seen as risk management in the face of uncertainty by exploring the spatial patterning of land-use activities over time. Dalarna county, an agriculturally marginal boreal forest environment, provides the opportunity for addressing change in terms of agricultural responses and other activities. C14 archaeological records complied by Dalarna Museum were the base of this analysis. The spatial and temporal components of these Boreal Forest records were analyzed in the open-source software QGIS, guided by a historical ecology framework. Human niches diversified and intensified during specific periods in the Boreal forest environment; our focus has been on how humans managed resource risk related to the ecological uncertainty within this forest environment characterized by long winters and short growing seasons. We conclude that constructed niches shaped the Boreal Forest, spanning its environmentally unique upland and lowland regions, into a more predictable environment. Tracking the diversity, multi-functionality, and intensity of these past land-use activities can provide insights for best practices in land management, not only for the Boreal Forest area, but also for elsewhere. These insights will assist in policy-making decisions, as the methodology is adaptable and replicable for various landscapes.

Abstract:
Maguey cultivators in the Basin of Mexico during the Middle and Late Postclassic (A.D. 1150-1521) periods pioneered the more agriculturally marginal parts of the environment, such as the sloping piedmont zone around the alluvial plain. In their land-use strategy, terraced interplantings of maguey and grain formed the house gardens (calmilli) of their villages. These villages were established sometime around the twelfth century, and by the time of Spanish Conquest they covered the piedmont zones of the Teotihuacan Valley, Texcoco region, and similar areas of the Basin of Mexico. Archaeological and ethnographic evidence permit reconstruction of the caloric productivity of this interplanted terrace system, using modern maguey yields. This productivity is compared with the needs of the maguey cultivators by looking at a particular archaeological example, the Aztec period village of Cihuatecpan, in the Teotihuacan Valley.

Abstract:
Impact of climate change on Indian rainfed agriculture was assessed using temporal NDVI data products from AVHRR and MODIS. Agricultural vulnerability was analysed using CV of Max NDVI from NOAA-AVHRR (15-day, 8 km) and MODIS-TERRA (16-day, 250 m) NDVI data products from 1982–2012. AVHRR dataset was found suitable for estimating regional vulnerability at state and agro-eco-sub-region (AESR) level while MODIS dataset was suitable for drawing district-level strategy for adaptation and mitigation. Methodology was developed to analyse NDVI variations with spatial pattern of rainfall using 10 X 10 girded data and spatially interpolating it to estimate Standard Precipitation Index. Study indicated large variations in vegetation dynamics across India owing to bio-climate and natural resource base. IPCC framework of vulnerability and exposure was used to identify vulnerable region extending from arid western India to semi-arid and dry sub-humid regions in central India and southern peninsula. This is a major agricultural region in the country with sizable human and livestock population with millions of marginal and small farm holdings. Exposure to climatic variability at local and regional levels have national implications and study indicated that over 122 districts extending over 110 mha was vulnerable to climate change that spread across 26 typical AESR in 11 states in India. Of the 74 mha under agriculture in the region, MODIS dataset indicated 47 mha as agriculturally vulnerable while coarser resolution of AVHRR dataset indicated a conservative estimate of 29 mha. First ever estimates of agricultural vulnerability for India indicates 20.4 to 33.1 % agricultural land under risk from climate change.

Abstract:
Seasonal migration is a common livelihood strategy among marginal and landless people of the western part of West Bengal. The National Sample Survey Organisation (NSSO) and Census data have failed to provide information on seasonal migration and livelihoods at the micro-level. The present study focuses on the nature, characteristics and factors of seasonal migration with its importance as a livelihood strategy among women agricultural labourers (WALs) in Soul Ponamara mouza of Hirbandh block at the micro-level. The study is based on primary data collection using a purposive sampling method and a semi-structured questionnaire, personal interview and focus group discussion. This study reveals that seasonal migration from Soul Ponamara to the adjacent agriculturally prosperous districts viz. Purba Bardhaman and Hooghly (4 to 6 times in a year) is a common livelihood strategy among WALs in the study area, and its proportion is almost equal to when compared to male migrants. The small size of agricultural land holding, existing monoculture system, lack of irrigation facilities, a limited job opportunity in the Soul Ponamara mouza and its surrounding area (Amjhuri, Bijardihi, Chaka Doba, Moshiara, Bamni and Rangametia) provoke women labourers to move out in searching of works. In contrast, high wage and massive demand for skilled and semi-skilled agricultural labourers during sowing and harvesting season in the destination area, that is, paddy and potato fields of Purba Bardhaman and Hooghly districts acted as a magnet to absorb these immigrants into the workforce. This study concludes that seasonal migration opted for employment and income generation is the primary livelihood strategy adopted by the rural WALs of this mouza to cope up with the existing poverty and food insecurity.

Abstract:
The paper addresses the influence of various types of taxes on changes in differential (Ricardian) land rent, and the economic performance of agricultural producers. Labour and capital taxes lead to higher prices for agricultural products, causing a decrease in consumer demand and lower income for agricultural producers (mostly utilizing marginal land). A polynomial single-product model has been used to demonstrate that reducing the tax burden on agricultural producers – specifically taxes on labour and capital – will result in increases in differential land rents on the average and relatively better plots, and/or the emergence of the rent on the marginal land. Thus, substituting labour and capital taxes for land/property taxes reduces the overall tax burden of agricultural producers on marginal lands.

Abstract:
This study deals with approaches for a social-ecological friendly European bioeconomy based on biomass from industrial crops cultivated on marginal agricultural land. The selected crops to be investigated are: Biomass sorghum, camelina, cardoon, castor, crambe, Ethiopian mustard, giant reed, hemp, lupin, miscanthus, pennycress, poplar, reed canary grass, safflower, Siberian elm, switchgrass, tall wheatgrass, wild sugarcane, and willow. The research question focused on the overall crop growth suitability under low-input management. The study assessed: (i) How the growth suitability of industrial crops can be defined under the given natural constraints of European marginal agricultural lands; and (ii) which agricultural practices are required for marginal agricultural land low-input systems (MALLIS). For the growth-suitability analysis, available thresholds and growth requirements of the selected industrial crops were defined. The marginal agricultural land was categorized according to the agro-ecological zone (AEZ) concept in combination with the marginality constraints, so-called ‘marginal agro-ecological zones’ (M-AEZ). It was found that both large marginal agricultural areas and numerous agricultural practices are available for industrial crop cultivation on European marginal agricultural lands. These results help to further describe the suitability of industrial crops for the development of social-ecologically friendly MALLIS in Europe.

Abstract. To examine the chemical composition and ethanol production of feedstocks grown on marginal lands, prairie cordgrass and switchgrass from waterlogged land, saline land, and saline water irrigated land were evaluated. Samples were pretreated using 1% w w-1 dilute acid at 160°C for 10 min, and simultaneous saccharification and cofermentation was conducted using industrial engineered . Samples grown on land irrigated with saline water had 2.8-fold higher total ash content compared to the other types of land, resulting in lower carbohydrate concentrations. Yeast fermented glucose and xylose simultaneously; almost all of the sugars were consumed, indicating that salts present in biomass ash did not inhibit yeast performance. Ethanol production from the waterlogged and saline lands was 2,500 to 4,700 L ha-1, which is comparable to that of samples grown on other agricultural lands. Prairie cordgrass and switchgrass grown on marginal lands could be potential feedstocks for cellulosic biofuel.

Abstract:
We assess empirically how agricultural lands should be used to produce the highest valued outputs, which include food, energy, and environmental goods and services. We explore efficiency tradeoffs associated with allocating land between food and bioenergy and use a set of market prices and nonmarket environmental values to value the outputs produced by those crops. We also examine the degree to which using marginal land for energy crops is an approximately optimal rule. Our empirical results for an agricultural watershed in Iowa show that planting energy crops on marginal land is not likely to yield the highest valued output.

Abstract:
The marginal fringe region of Canada is an agricultural area which is near the environmental and economic limits for commercial agricultural production. Combinations of physical factors and social and economic influences result in an area that experiences dramatic shifts in land use and agricultural development. Government policy is, however, a potentially significant controlling and stabilizing factor in the region's development. It is therefore fundamentally important that government plan its diverse functions and responsibilities in the marginal fringe to ensure an effective, equitable and efficient allocation of society's scarce resources. This thesis analyses existing planning programs for the development of agriculture on Crown land in Canada's marginal fringe region. It seeks to determine whether these programs have the potential to ensure the efficient and equitable development of agricultural land. This thesis also addresses the problem of how we should effectively develop our shrinking supply of undeveloped arable land and whether existing planning programs adequately address the major issues in the development process. The methods of investigation include a series of three case studies: St. John's, Newfoundland; Fort Nelson, British Columbia and; Fort Vermilion, Alberta. The case studies are analysed using a framework based on an idealized planning process developed in-the first chapter. This framework is applied to representative planning exercises in each case in order to illustrate the overall planning program's strengths and weaknesses. Based on this broad analysis, I present, in conclusion, the most crucial questions for developing effective planning programs in the marginal fringe and apply these questions to the cases studied. Official reports and surveys, detailed correspondence, personal and telephone interviews, and first-hand experience form the basis for analysis in the case studies. A literature review is the basis for the contextual elements developed in Part I of this thesis. The results of this study raise a number of concerns about existing planning programs for the agricultural development of Crown land in the marginal fringe, particularly in British Columbia and Newfoundland. The crucial issues for developing effective planning programs in the marginal fringe include the need for a clearly articulated, stable yet flexible, program focussing on the marginal fringe region. The agricultural lead agency's involvement is crucial for these programs. Further questions consider how well environmental factors are inventoried, evaluated and communicated to decision-makers; whether adequate socio-economic assessments are permitted; if alternative resource development options to agriculture are considered; whether government programs related to agricultural development are effective or whether they are inconsistent with planning program objectives, and whether the public understand and support the planning program. Planning the agricultural development of Crown land in the marginal fringe is in its infancy. Sudden changes to programs, as in British Columbia, and funding deadlines, as in Newfoundland, are harmful to the efficient and effective development of frontier resources and they erode government credibility. Some jurisdictions, such as Alberta, are making rapid strides in applying many of the traditional planning techniques, although social and economic assessment is very weak or absent altogether in each of the programs studied. Usually, decisions are based on a narrow assessment of environmental factors and there are often significant gaps in essential data, especially climate. Alternative resource development options to agriculture are seriously considered only in British Columbia. Only in Alberta has the vital element of public support begun to be appreciated. Elsewhere, public involvement is, more or less, neglected or mishandled. In conclusion, this thesis raises a number of issues requiring future research, related mainly to socio-economic assessment and planning program development. Also a series-of more detailed normative principles are offered for the improvement of planning programs for the agricultural development of Crown land in the marginal fringe.

Abstract:
The study concerns the effects on the course of agricultural land-use change of the local domination of land occupancy by sub-full-time farms; in particular the effect of non-agricultural occupations on the land-use of individual farm operators is central. Land-use changes in the West Highlands of Scotland (1947-79) were charted for 66 Parishes, which were subjected to a hierarchical fusion of 'similar experience' of change. Resultant clusters were compared in terms of structural attributes. Differentiation was found at two levels: between areas of high viz low percentages of part-time holdings and within the sub-full-time fractions, related to relative proportions of holdings of 40-135, and 135-270 Standard Man Days. 'Insignificant' holdings (<40 SMDs) were found not to be of a characteristic land-use 'type' but instead operated enterprises of similar form to larger units. In three areas of crofting townships land-use and enterprise characteristics were found not to be a sole function of size of holdings or labour availability, (estimated from household demographic and employment criteria). Non-farm occupational characteristics (full-time; part-time; seasonal etc) related to the scale of enterprise but less so to the type of enterprise. Occupants with off-farm work did not specialise per se in low-labour demanding activities. Linear programming was used to estimate optimal land-use intensity from land capability and labour data. Occupational factors related to sub-optimal land-use intensity as did occupants' age. A method derived from Point Score Analysis of decision-making factors showed that certain factors serve as 'constraints' on choices of specific groups of individuals. Off-farm work was found to be the most important such constraint.

AN ABSTRACT OF THE THESIS OF Joshua B. Nickelson, for the Masters of Science degree in Forestry, at Southern Illinois University Carbondale TITLE: EVALUATING THE SUCCESS OF OAK AFFORESTATION ON FORMER AGRICULTURAL FIELDS IN SOUTHERN ILLINOIS Major Professor: Dr. Eric Holzmueller The establishment of oak (Quercus spp.) plantations has increased over the past two to three decades to reduce fragmentation and promote wildlife habitat throughout the Midwestern United States. However, influences such as competing vegetation, previous land cover, plantation size, and site preparation techniques may have varying outcomes on restorative successes. We established 219 plots (.02 ha) in 29 oak plantations located within Crab Orchard National Wildlife Refuge (Williamson County, Illinois) 15-18 years after mechanical planting. Sampling data for all trees over breast height included species, diameter, and lianas existence on the main bole of the tree. Additionally, free-to-grow status was recorded for all oak saplings and estimated cover of the exotic invasive shrub Elaeagnus umbellata and vine Lonicera japonica were documented. Results show significantly higher numbers of total oaks and free-to-grow oaks in plantings previously cropped in clover and soybeans when compared to the fallow sites host to brush species that received treatment (mowing and or herbicidal application). Significantly less oaks in the soybean and clover categories possessed a vine on the main bole of the tree when compared to the treated brush sites. Brush sites showed a significantly less number of total trees compared to clover and soybean covers and a higher percent of autumn olive cover (%) compared to soybeans. No significance was found in the percent of oaks with a vine, the percent of oaks overtopped, E. umbellata density or L. japonica cover (%) across the four previous vegetation categories. One treatment of pre-planting mowing and herbicidal application is not effective on fallow sites that are host to early successional species and money should not be invested on Quercus trees or mowing and herbicidal treatments in these scenarios. The results suggest that it is best to plant Quercus species immediately following clover or soybean harvest on abandoned agricultural lands before early successional species become established.

Abstract:
Wild bees provide essential pollination service to both agricultural crops and wild flowering plant species. The decline of wild bee species has been associated with a number of different threats, primarily the loss of natural habitat. The Delta Farmland & Wildlife Trust (DF&WT), a non-profit conservation organization, incentivizes farmers to plant hedgerows consisting of native shrubs and trees on the edge of their production fields, mainly to create habitat for wildlife in the Agricultural Land Reserve (ALR) of Delta, British Columbia. In this study, the value of DF&WT’s planted hedgerows was evaluated as foraging habitat for wild bees at both the farm and landscape-scale. During the summers of 2015 and 2016, I surveyed bees and flowers in planted hedgerows, as well as the two other most dominant field margin habitats, remnant hedgerows and grass margins. The relationship between floral resources and bees, as well as bee-flower visitations was analyzed and compared among these three habitat types. These empirical data were then used to parameterize the Conefor model, to evaluate the network of field margin patches within the agricultural landscape for their relative importance in landscape connectivity for wild bees. Overall, wild bees collected from flowers and pan traps were significantly more abundant, species rich and diverse in grass margins compared to planted and remnant hedgerows. While the strongest relationship was found between floral abundance and bee abundance, it did not explain the differences between habitat types alone. Bee-flower visitation records revealed a preference for herbaceous species mostly found in grass margins while only few recommended plant species for hedgerow plantings were visited. The results indicate that grass margins could be a valuable alternative conservation approach or addition to woody hedgerows if properly planned and managed. Connectivity indices generated by Conefor identified four grass margin patches that most contributed to overall landscape connectivity for bees with different dispersal abilities. These results can be used to help improve field edge management and the spatial targeting of activities by the DF&WT to improve the conservation of wild bee species.

Full text
Abstract:
La Syrie centrale connaît au début de la période byzantine, et en particulier au Ve et au VIe siècle, un fort mouvement d’expansion des sédentaires vers l’est, qui coïncide avec une importante mise en valeur de ces nouveaux territoires. Comme pour d’autres régions de Syrie et du Proche-Orient à la même époque, un optimum climatique – pourtant déclinant – semble avoir permis la conquête et l’exploitation agricole de nouveaux terroirs dans une zone marginale qui n’avait jusqu’alors connu qu’une occupation sédentaire ponctuelle. La Syrie centrale est caractérisée par des milieux aux potentiels agronomiques très différents, souvent imbriqués. Le peuplement et la mise en valeur y sont soumis à la double contrainte de l’aridité climatique et édaphique, qui s’exerce avec une prégnance croissante vers le sud et l’est. Ces conditions, qui s’améliorent localement à la faveur de niches écologiques, ont permis à des politiques de mise en valeur et à des économies distinctes, souvent complémentaires, de voir le jour.Dans une région où les cités paraissent en grande partie absentes, l’économie repose d’abord sur les villages et sur quelques bourgs qui possédaient manifestement une orientation commerciale spécifique. Aux côtés des agglomérations, et souvent d’autant plus nombreux que les conditions d’implantation sont délicates, des fermes et des monastères s’affirment comme des acteurs économiques apparemment indépendants et souvent prospères. Des entités géographiques relativement homogènes ont donné lieu à une répartition des différentes formes de peuplement et à des économies microrégionales spécifiques. Si l’agriculture vivrière reste la règle, il semble bien cependant qu’on observe une spécialisation locale des productions : culture du blé et accessoirement plantations à l’ouest, oléiculture et peut-être viticulture dans les plateaux basaltiques du nord-ouest et vraisemblablement un élevage spéculatif, qu’on doit probablement attribuer à des populations sédentaires, dans les secteurs sud et est
In Late Antiquity, especially between the 5th and 6th centuries, Central Syria witnessed a strong expansion of sedentary settlements eastward, which coincided with a significant agricultural development of these new territories. As for other areas in Syria and Near-East at the same period, a waning climatic optimum seems to have allowed byzantine population to settle down in marginal areas which barely experienced hitherto sedentary occupation and farm nearly unbroken lands.Central Syria is made up of various landscapes, sometimes deeply nested, with contrasted agricultural potential. Settlements and agricultural exploitation are affected by an increasingly significant climatic and edaphic aridity eastward and southward. These conditions, which may locally improve thanks to ecological niches, enabled specific and often complementary substance strategies to develop.In a country whence cities are virtually absent, villages and a few market towns seem to be at the very root of the regional economy. Along with agglomerations, scattered habitats – namely farmsteads and monasteries –, more numerous under heavy bioclimatic constraints, would appear as independent and apparently prosperous economic players.Homogeneous geographic areas led to specific settlement patterns and different economic orientations. Food-producing agriculture remains the rule, but a local productive specialization may be noticed: mainly wheat production and incidentally plantations westward, olive-growing and maybe wine-growing as well in the north-west basaltic plateaus and presumably speculative livestock exploitation eastward and southward, probably mostly due to sedentary populations

Abstract:
AbstractFood production in Kenya and Africa in recent past has experienced vagaries of weather fluctuations which ultimately have affected crop yield. Farming in Kenya is localized in specific Agro-ecological zones, hence understanding crop growth responses in particular regions is crucial in planning and management for purposes of accelerating adoption. A number of strategies for adoption and adaptation to changing weather patterns have been deployed yet only limited challenges have been partially addressed or managed. This chapter examines previous methods used in classifying agro-ecological zones and further provides additional insightful parameters that can be adopted to enable farmers understand and adapt better to the current variable and unpredictable cropping seasons. The chapter scrutinizes past and current documented information on agro-ecological zonal valuations coupled with the use of earth observation components such as air temperature at surface, land surface temperature, evapotranspiration, soil, temperature, and soil and moisture content in order to better understand and effectively respond to new phenomena occurring as a result of climate change in the marginal agricultural areas. Significant variations in precipitation, ambient temperature, soil moisture content, and soil temperature become evident when earth observation data are used in evaluation of agro-ecological lower midland zones IV and V. The said variations cut across areas within the agro-ecological zones that have been allocated similar characteristics when assigning cropping seasons. The chapter summarizes the outcomes of various streams of contributions that have reported significant shifts or changes in rainfall and temperature patterns across Kenya and wider Eastern Africa region. The chapter highlights the need for re-evaluation of the agro-ecological zones based on the recent earth observation datasets in their diversity. The research emphasizes the use of multiple climate and soil-related parameters in understanding climate change in the other marginal areas of Kenya.

Abstract:
Land degradation usually occurs on drylands (arid, semiarid, and dry subhumid areas). According to the United Nations Convention to Combat Desertification held in Paris in 1994 (UNCCD, 1999), drylands are defined as those lands (other than polar and subpolar regions) where the ratio of annual precipitation to potential evapotranspiration falls within the range of 0.05–0.65. Land degradation causes reduction in the biological or economic productivity of those lands that may support cropland, rangelands, forest, and woodlands. Land degradation threatens culturally unique agropastoral and silvopastoral farming systems and nomadic and transhumance systems. The consequences of land degradation are widespread poverty, hunger, migration, and creation of a potential cycle of debt for the affected populations. Historical awareness of the land degradation was cited, mainly at the local and regional scales, by Plato in the 4th century B.C in the Mediterranean region, and in Mesopotamia and China (WRI, 2001). The occurrence of the “dust bowl” in the United States during the 1930s affected farms and agricultural productivity, and several famines and mass migrations, especially in Africa during the 1970s, were important landmarks of land degradation in the 20th century. It is estimated that more than 33% of the earth’s land surface and 2.6 billion people are affected by land degradation and desertification in more than 100 countries. About 73% of rangelands in dryland areas and 47% of marginal rain-fed croplands, together with a significant percentage of irrigated croplands, are currently degraded (WRI, 2001). In sub-Saharan Africa, land degradation is widespread (20–50% of the land) and affects some 200 million people. This region experiences poverty and frequent droughts on a scale not known anywhere else in the world. Land degradation is also severe and widespread in Asia, Latin America, as well as other regions of the globe. Continuous land degradation is accelerating the loss of agricultural productivity and food production in the world. Over the next 50 years, food production needs to triple in order to provide a nutritionally adequate diet for the world’s growing population. This will be difficult to achieve even under favorable circumstances.

Abstract:
The market analysis report that is submitted to the decision maker (see chapter 4) should include a descriptive, qualitative overview of the context the real estate project has to the existing and changing urban environment. To better accomplish this task, one should have knowledge of the general theory regarding the market processes that bring about land use and urban form. This chapter presents three relevant general theories of land use and land value. Together, these general theories provide a general qualitative understanding of how the existing urban environment came to be and allows the analyst to prognosticate the trajectory of change of urban land uses and land values. The first two of the general theories presented here arose out of an attempt to explain agricultural land values and land uses. Why should a discussion of the agronomy sector be included in a book on urban real estate analysis? First, all the general theories relevant to land values and land use, and their spatial distribution within a city, are part of an intellectual heritage that dates from general theories of agricultural land values and land use. Second, much of new urban development occurs at those suburban margins. To understand development at the suburban margins, there must be an understanding of the nonurban land uses and land values at those locations. The third general theory explains spatial equilibrium and its role in shaping urban land values and land uses. Two eighteenth-century theorists, David Ricardo and Johann Heinrich von Thünen, are credited for having created a vast and sometimes opposing literature on land valuation. Ricardo’s economic theory was based upon the relative productivity of sites. In contrast, von Thünen’s geographic theory was focused on the locational component of land values and land use. The juxtaposition of these two competing giants of land theory in many respects still differentiates economists and geographers even today. After the theories of Ricardo and von Thünen are presented, an overview of the consumption theory of land rent (CTLR) is provided. The CTLR is my general theory and methodology for evaluating urban housing land use, land values, and urban form (Thrall 1980, 1987, and see 1991).

Abstract:
This chapter explores socioeconomic interactions between “Poor Whites” or “Redlegs” and Afro-Barbadians as interpreted through material culture and a particular reading of a Barbadian plantation landscape. The tenantry of Below Cliff, now shrouded in dense forest, is located on the “rab” land or marginal zone of Clifton Hall plantation deemed unsuitable for large-scale agricultural production. Despite the marginality of the space in terms of plantation production and a perceived socioeconomic isolation of island “poor whites” in general, Below Cliff was a space of heightened interracial interaction. I argue that such seemingly marginal spaces (as well as the people who inhabit them) are significant arenas through which to explore the dynamic and nuanced race relations that play out in everyday life on and around the plantation. While plantation slavery was crucial in the development of modern racial ideologies and hierarchies, including attempts to rigidly impose and police racial boundaries, archaeological evidence suggests that on the local level these boundaries were exceedingly porous.

Abstract:
The main objective of the research was identifying the phenomena that generate land degradation (LD), in the Basilicata region’s landscape (southern Italy),with a MEDALUS (Kosmas et al., 1999) and RS approach, through the help of 6 main indicators (Soil Quality Index, Climate Quality Index, Vegetation Quality Index, Management Quality Index, Landslide Risk Index, Water Availability Index) and through NDVI differencing thresholds evaluation in time intervals, covering a 20 years’ time span going from 2000 to 2020. The Basilicata region saw this phenomenon increased in the past centuries, both because there has never been any monitoring of LD at regional planning-level, and for the fact that historically the region suffered severe agricultural stress, with enormous deforestations that have led to soil degradation and consequently to the depopulation of the internal marginal areas. These elements caused a strong impact on the potential regional progress, both economic and social, leading to a huge ecological damage. The methodology helped to outline the future LD predictions for the region, and consequentially its management possibilities and implications in relation to this critical issue, in order to maintain or restore the pre-existing values, thus integrating the study of Environmentally Sensitive Areas (ESAs) in a scientific validated Decision Support System (DSS), for new coherent and integrated landscape strategies in marginal territories. This objective derives from recognizing the landscape as defined in the European Convention (Council of Europe, 2000) as an important element for community interest, on the cultural, ecological, environmental and social point of view, and as a resource for economic development, pursued by enhancing the preservation of its fundamental component of cultural and natural heritage.
