Northern Adriatic

In many coastal regions (e.g. parts of the North Sea, northern Adriatic Sea, Baltic Sea, Great Barrier Reef lagoon, wider Caribbean, coastal areas of the USA) there is large-scale, and in some cases chronic, eutrophication. In some regions, the link between eutrophication and the destruction of an ecosystem is obvious, with excessive algal growth and water-column anoxia. In other cases, particularly in more fragile ecosystems such as coral-reef and seagrass areas, the links are not so obvious, yet the impacts of eutrophication in such regions can be devastating. Eutrophication can have more insidious effects such as contributing directly to the mortality of fish, marine mammals and sea birds and indirectly to disease or death in humans owing to the accumulation of biotoxins in seafoods. Increased development and changes in land-use patterns in the coastal zone have increased the loading of diffuse or non-point nutrients. In areas subject to runoff and soil erosion, most of the nutrient load is transported in particulate form. In such cases, the loads of nutrients discharged from cropping lands are typically an order of magnitude greater than those discharged from pristine forested areas. Nutrient export from pasture lands, whether these are fertilized or not, is also significantly greater than that from pristine areas, and in many cases the total loads from such areas are far higher than those from intensively farmed areas. A reduction in nutrient discharges to coastal waters will require careful land-use planning. The importance of the particulate fraction in the nutrient load necessitates effective control of soil erosion. The hydrological and nutrient linkage between terrestrial and marine ecosystems must be emphasized. Collective management of hinterland and coastal-zone resources could initiate remediation of a serious and growing problem.

AbstractAgricultural land expansion and intensification, driven by human consumption of agricultural goods, are among the major threats to environmental degradation and biodiversity conservation. Land degradation can ultimately hamper agricultural production through a decrease in ecosystem services. Thus, designing viable land use strategies is a key sustainability challenge. We develop a model describing the coupled dynamics of human demography and landscape composition, while imposing a trade-off between agricultural expansion and intensification. We model land use strategies spanning from low-intensity agriculture and high land conversion rates per person to high-intensity agriculture and low land conversion rates per person; and explore their consequences on the long-term dynamics of the coupled human-land system. We seek to characterise the strategies’ viability in the long run; and understand the mechanisms that potentially lead to large-scale land degradation and population collapse due to resource scarcity. We show that the viability of land use strategies strongly depends on the land’s intrinsic recovery rate. We also find that socio-ecological collapses occur when agricultural intensification is not accompanied by a sufficient decrease in land conversion. Based on these findings we stress the dangers of naive land use planning and the importance of precautionary behaviour for land use management.

The Impact

The impact of the British style of land-use planning upon the outcomes of private housing development and the housing market is examined. A unique cross-sectional database is constructed, and the medium-term elasticity of new housebuilding supply is estimated as a locally variable function of prices, costs, and land supply, with an explicit planning function. The model developed enables quantified projections to be made of the effect of specified changes in planning policy. The policy changes examined include large-scale increases in the volume of land released, changes in the mix of land released, and the use of planning agreements to pay for infrastructure or social housing.

Planning Processes

Coastal areas are particularly sensitive because they are complex, and related land use conflicts are more intense than those in noncoastal areas. In addition to representing a unique encounter of natural and socioeconomic factors, coastal areas have become paradigms of progressive urbanisation and economic development. Our study of the infrastructural mega project of Patimban Seaport in Indonesia explores the factors driving land use changes and the subsequent land use conflicts emerging from large-scale land transformation in the course of seaport development and mega project governance. We utilised interviews and questionnaires to investigate institutional aspects and conflict drivers. Specifically, we retrace and investigate the mechanisms guiding how mega project governance, land use planning, and actual land use interact. Therefore, we observe and analyse where land use conflicts emerge and the roles that a lack of stakeholder interest involvement and tenure-responsive planning take in this process. Our findings reflect how mismanagement and inadequate planning processes lead to market failure, land abandonment and dereliction and how they overburden local communities with the costs of mega projects. Enforcing a stronger coherence between land use planning, participation and land tenure within the land governance process in coastal land use development at all levels and raising the capacity of stakeholders to interfere with governance and planning processes will reduce conflicts and lead to sustainable coastal development in Indonesia.

Abstract Cropland displacement is a worldwide land-use phenomenon that involves replacing cropland occupied by urbanization with newly developed cropland in remote areas. Large-scale cropland displacement to some extent helps secure food supply to the growing urban population but also drives a great need for grain transport, which leads to rising energy consumption and carbon emission. Here we show a systematic evaluation of the carbon emission associated with grain transport at the prefecture-level in China in 1990 and 2015. We found that the total emission of grain transport in China more than doubled from 4.46 million-ton to 10.73 million-ton during this period. Cropland displacement contributed more than 60% of the increased carbon emission, while dietary change and population growth contributed 31.7% and 16.6%, respectively. In contrast, improvement of transport infrastructures offset 0.54 million-ton of the increased emission. Based on the research results, we provide policy suggestions on reducing grain transport carbon emission in China in terms of land use planning, grain-based value chain, as well as transport development.

Lulc Changes

LULC changes are major environmental challenges in many parts of the world which are adversely affecting ecosystem services. This study was aimed to analyze LULC changes in the ecological landscape of Ethiopia CRV areas from 1985 to 2015. Satellite images were accessed and pre-processing and classification is done. Major LULC types were detected and change analysis was executed. Nine LULC changes were successfully evaluated. The classification result revealed that in 1985, 44.34% of the land was covered with small scale farming followed by mixed cultivated/acacia (21.89%), open woodland (11.96%), and water bodies (9.77%). Whereas for the same study year open grazing land, forest, degraded savannah and settlements accounted the smallest proportion. Though the area varied among land use classes, the trend of share occupied by the LULC types in the study area remained the same in 1995 and 2015. Increase in small and large scale farming, settlements and mixed cultivation/acacia while a decrease in water bodies, forest, and open woodlands is noted. About 86.11% of the land showed major changes in land use/cover. Lastly, DPSIR framework analysis was done and integrated land use and development planning and policy reform are suggested for sustainable land use planning and management.

The article considers consequences of the large-scale reform of control and supervisory activities, which was informally called "regulatory guillotine", as well as a number of other high-profile innovations at the organization of land management and agrarian education. The main attention is paid to the fact that all these innovations will lead to new testing and evaluation activities of Universities, as well as to assurance that graduates of land surveying and agricultural departments should be ready to carry out their future professional activity in a new environment. Therefore, it will be necessary to clarify their competencies and update training materials.

Participatory land-use planning (LUP) is often promoted as a solution to various environment-related challenges. In Tanzania, planning processes often represent a stage in the conversion of village lands to different uses, such as wildlife conservation or large-scale farming. LUP in Tanzania is frequently dominated by powerful local, national, or international elites, resulting in loss of rights over village land despite the opposition of many villagers. Contemporary planning involves digital technologies such as global positioning system units, which enable easier storage and sharing of geospatial data. Using assemblage theory, and based on key informant interviews conducted in Arusha and Kilimanjaro Regions of Tanzania in 2015, this article shows that LUP, particularly when it involves digital technologies, is used to not only to change land uses but also to strengthen linkages between different organizations, reinforce certain narratives of environmental change, and legitimize particular forms of external intervention.

Forested landscapes in west-central Alberta are facing increased pressures from forest harvesting and other land-use activities, which may alter the movements and distribution of Wolves and ungulates. Information on habitat use by Wolves in logged forests is scarce, potentially limiting effective land-use planning in the boreal forest. Nine Wolves, from four Wolf packs, were fitted with GPS radiocollars in the Rocky Mountain foothills, near Grande Cache, Alberta (2000-2001). We found Wolves did not use the landscape randomly, but rather exhibited a significant preference for non-forested natural habitats (shrubs, water), relative to their availability. Within forest habitats, Wolves used cutblocks proportionately more than unharvested forest and non-forested anthropogenic habitats (pipelines, clearings); however, selection of forest cutblocks was not statistically significant. We found no evidence that Wolves preferred or avoided forest cutblock edges. Wolf pack territories contained various levels of timber harvesting, but most areas were still in the early stages of harvest. Nevertheless, these areas have been allocated for large-scale harvesting. Understanding the potential responses of Wolves to rapidly changing landscape mosaics poses a significant challenge to researchers and managers, but such information is important to informing future land-management and conservation strategies for boreal forest Wolf-prey systems.
