Poor Management

Modern intensive monocropping system is becoming unproductive, pest ridden, loss incurring, and resource depleting and hence turning out to be untenable. Lack of discrimination in input use by farm managers and overall poor management are accelerating degradation and desertification processes, and loss of biodiversity particularly add in endangered regions. While, properly designed diverse and strategically located tree/seasonal crop based land use systems can contribute to ecologic services by mitigation land degradation, climate change and desertification, while conserving natural resources and biodiversity. Besides providing, diverse goods and services, on-farm diversity can be considered as an adoptive strategy in areas climatically and biologically vulnerable. Being a potential C sink, tree based land use systems can also mitigate negative impacts of CO2 emission. As green belt/bank these have an important role in maintaining air, water and soil quality in mining and industrial areas. The so-called cellulosic feedstocks can be grown on marginal land, enhance soil fertility by promoting the growth of various soil organisms, and provide a climate- friendly source of energy. There are plenty of underexploited but potential plant species which can find niche in the existing agroecosystems with substantial addition to total production while contributing sufficiently to ecological services. These needs to be identified and useful models are developed for specific situations.

Land Use Development

The land and town planning legislation concerning the planning of land use development within the united territorial communities (UTC) is considered. It is found that legislative norms need to be finalized. The necessity of updating the existing land management documentation developed prior to the adoption of the Law of Ukraine "On Land Management" and changes in the structure of urban development in connection with the adoption of the Law of Ukraine "On Regulation of Urban Development" was proved as they do not ensure the integrity of the planning process within the territories of these communities through their institutional incapacity (proved by the example of the Palan Unified Territorial Community of the Uman district of the Cherkasy region). The priority of land management and urban planning documents as the most influential tools in planning the development of land use systems in UTC is scientifically grounded and their interdependence established.

Significant Difference

The present study was conducted to investigate the seasonal effects of five land use systems (LUSs), i.e., wheat–rice (Triticum aestivum—Oryza sativa) system, sugarcane (Saccharum officinarum), orange (Citrus sinensis) orchard, safeda (Eucalyptus globules) forest, and grassland, on soil quality and nutrient status in the lower Satluj basin of the Shiwalik foothills Himalaya, India. Samples were analyzed for assessment of physico-chemical properties at four soil depths, viz., 0–15, 15–30, 30–45, and 45–60 cm. A total of 120 soil samples were collected in both the seasons. Soil texture was found to be sandy loam and slightly alkaline in nature. The relative trend of soil organic carbon (SOC), macro- and micro-nutrient content for the five LUSs was forest > orchard > grassland > wheat–rice > sugarcane, in the pre- and post-monsoon seasons. SOC was highly correlated with macronutrients and micronutrients, whereas SOC was negatively correlated with soil pH (r = −0.818). The surface soil layer (0–15 cm) had a significantly higher content of SOC, and macro- and micro-nutrients compared to the sub-surface soil layers, due to the presence of more organic content in the soil surface layer. Tukey’s multiple comparison test was applied to assess significant difference (p < 0.05) among the five LUSs at four soil depths in both the seasons. Principle component analysis (PCA) identified that SOC and electrical conductivity (EC) were the most contributing soil indicators among the different land use systems, and that the post-monsoon season had better soil quality compared to the pre-monsoon season. These indicators helped in the assessment of soil health and fertility, and to monitor degraded agroecosystems for future soil conservation.

New Phase

The digitisation of data about the world relevant to business has given rise to a new phase of digitalisation of business itself. The digitisation of data about people has linked with the notions of information society, surveillance society, surveillance state and surveillance capitalism, and given rise to what is referred to in this article as the digital surveillance economy. At the heart of this is a new form of business model that is predicated on the acquisition and consolidation of very large volumes of personal data, and its exploitation to target advertisements, manipulate consumer behaviour, and price goods and services at the highest level that each individual is willing to bear. In the words of the model’s architects, users are ‘bribed’ and ‘induced’ to make their data available at minimal cost to marketers. The digital surveillance economy harbours serious threats to the interests of individuals, societies and polities. That in turn creates risks for corporations. The new economic wave may prove to be a tsunami that swamps the social dimension and washes away the last five centuries’ individualism and humanism. Alternatively, institutional adaptation might occur, overcoming the worst of the negative impacts; or a breaking-point could be reached and consumers might rebel against corporate domination. A research agenda is proposed, to provide a framework within which alternative scenarios can be investigated.

AbstractManagement of secondary tropical forests: a new perspective for sustainable use of forests in Asia. The decline of primary forests in the tropics is leading to a reassessment of the role secondary forests might play within the context of tropical forest management. Recent research has shown that secondary forests in the tropics can be both rich in species and complex in terms of stand structure. There is, moreover, a growing recognition of the importance of secondary forests for traditional subsistence economies in the tropics and of their economic potential for land use systems in the future. Management of secondary forests in Asia as an alternative to the extraction of timber from primary forests but also as one among other options to intensify traditional land use systems has a potential for the future especially because of the existence of vast tracts of valuable secondary forest cover, and because of the store of traditional knowledge that can still be found in tropical Asia.
