About two billion rural individuals depend on agricultural systems associated with a high amount of risk and low levels of yield in the drylands of Asia, Africa, and Latin America. Human activities, climate change and natural extreme events are the most important drivers of desertification. This phenomenon has occurred in many regions of Iran, particularly in the villages in the periphery of the central desert of Iran, and has made living in the oases so difficult that the number of abandoned villages is increasing every year. Land abandonment and land-use change increase the risk of desertification. This study aims to respond to the research questions: (i) does the planning of green infrastructures on the desert margin affect the distribution and balance of the population? (ii) how should the green belt be designed to have the greatest impact on counteracting desertification?, and (iii) does the design of productive landscape provide the solution? Through a wide-ranging and comprehensive approach, this study develops different scenarios for designing a new form of green belt in order to sustainably manage the issues of environmental protection, agricultural tradition preservation and desertification counteraction. This study proposes a new-traditional greenbelt including small low-cost and low-tech projects adapted to rural scale.

SUSTAINABILITY, vol. 10, p. 1-20. doi: 10.3390/su100411 Abstract Terraced Mediterranean areas are distinctive man-made landscapes with historical and cultural relevance. Terraced land abandonment driven by physical and economic constraints had important ecological consequences. This study focuses on a marginal agricultural district in southern Latium, central Italy, where terracing dated back to the Roman period and olive groves are the main agricultural use. A diachronic assessment of land-use transformations was carried out to identify landscape dynamics and drivers of change around terraced land. Terraced landscape systems (TLS), derived from spatial aggregation of neighboring terraced patches, have been analyzed for landscape transformations considering slope as the main stratification variable. Structural and functional characteristics of TLS were analyzed using a landscape ecology approach. Soil bio-chemical indicators were finally assessed to study the impact of terraced olive agro-ecosystems on soil-related ecosystems services. The empirical findings outlined that TLS in central Italy are sensitive to urbanization and land abandonment. Cultivated terraces prevailed up to gentle-medium slope land, uncultivated and wooded areas dominated terraces on steep slopes. In this context, poly-cultural olive groves proved to be a cropping system particularly resilient to global change, irrespective of land slope. Terraced systems and extensive poly-cultural olive groves play a role in preserving ecosystem integrity, landscape quality, soil functionality and, therefore, environmental sustainability.

Understanding the latent relationship between rural landscape and biodiversity conservation is of key importance when aiming to preserve food security, ecosystem services and the quality of the environment. Crop intensification negatively impacted the biodiversity of rural areas and was followed by the adoption of mono-cultural production models. The conservation of traditional agricultural landscapes (TALs) based on traditional land management approaches, ensures the conservation of the ecosystem’s complexity and high levels of biodiversity. In Europe, Mediterranean TALs are threatened by a combination of anthropogenic and natural factors. The need to preserve TALs is widely recognized despite the lack of comprehensive information and collective policy strategies. On the other hand, inventories are available for endangered cultivars, typical products and traditional agricultural practices. This study focuses on the relationship between TALs and the use of local varieties/typical products. The analysis will: (i) define, map and characterize the tree-crop based traditional landscapes in one of the Mediterranean regions (Latium, central Italy) through a land-use change detection analysis (1960–2000) and (ii) identify the most endangered TALs based on environmental risk factors, on autochthonous agro-biodiversity at risk of varietal erosion and on traditional products that risk to disappear. Results prove that the most endangered rural landscapes are the ones located on fringe and marginal lands due to climate aridity and soil erosion. The identification of the endangered TALs contributes to constructing more effective strategies for the preservation of agro-biodiversity and natural ecosystem functionality.

This study was conducted to identify the farmers’ characteristics that act as factors in influencing their knowledge on indigenous agricultural practices. The study was conducted in the state of Kerala among 40 farmers each of ten selected horticultural crops. Step wise regression analysis and multiple linear regression analysis were employed to identify the influencing factors. The study revealed that age, farm power status, innovativeness, rational orientation, communication status, and social participation status positively influence knowledge of farmers on indigenous agricultural practices whereas material status, educational status, and family status were the important characteristics of farmers negatively influencing the knowledge of indigenous practices.
