The Yukon government has not yet submitted its recommendations for the Dawson Regional Land Use Plan, despite saying earlier that it would do so by last month.

The station is being developed on a massive scale, providing commuting area on the southern side, in view of the crammed locality on the northern side

From 9 to 11 November in Vienna, Austria the EU H2020 project Detecting changes in essential ecosystem and biodiversity properties – towards a Biosphere Atmosphere Change Index: BACI has organised a special workshop titled "Remote sensing applications related to land use/change" with the aim to facilitate co-design and co-production of knowledge with regard to innovative applications of remote sensing products.

EU BON project partner Duccio Rocchini was among the invited lecturers at the event. His talk titled "Like in a Rubik’s cube: Recomposing Biodiversity Information by Remote Sensing Data" introduced some experience from EU BON.

The overarching objective of BACI is to tap into the unrealized potential of existing and scheduled space-borne Earth observation data streams to detect changes in ecosystem functioning and services that have repercussions for essential biodiversity variables, land use potentials, and land-atmosphere interactions.

The planetary boundaries framework attempts to set limits for biodiversity loss within which ecological function is relatively unaffected. In a recent article in Science Newbold et al. present a quantitative global analysis of the extent to which the proposed planetary boundary has been crossed. 

Abstract: 

Land use and related pressures have reduced local terrestrial biodiversity, but it is unclear how the magnitude of change relates to the recently proposed planetary boundary ("safe limit"). We estimate that land use and related pressures have already reduced local biodiversity intactness—the average proportion of natural biodiversity remaining in local ecosystems—beyond its recently proposed planetary boundary across 58.1% of the world’s land surface, where 71.4% of the human population live. Biodiversity intactness within most biomes (especially grassland biomes), most biodiversity hotspots, and even some wilderness areas is inferred to be beyond the boundary. Such widespread transgression of safe limits suggests that biodiversity loss, if unchecked, will undermine efforts toward long-term sustainable development.

Delivering Sustainable Food and Land Use Systems: The Role of International Trade Research paper sysadmin 20 September 2019

This paper explores a set of core trade-related issues affecting the food and land use system, and proposes constructive ways forward in reconfiguring the global trading system towards delivering a more sustainable and healthy diet for all.

• Meeting future global food security requirements is not just about quantity; it is also about meeting growing needs in a way that safeguards human as well as planetary health. But national priorities and policies often remain out of sync with aspirations for more sustainable and healthy food systems.
• International trade and trade policies play an ambiguous role in the current food system. With 80 per cent of the world’s population depending on imports to meet at least part of their food and nutritional requirements, trade has a unique function in offsetting imbalances between supply and demand. However, in the absence of effective regulatory frameworks or pricing frameworks that internalize environmental, social or health costs, trade can exacerbate and globalize challenges associated with food production and land use trends such as deforestation, land degradation, greenhouse gas emissions, biodiversity loss and the shift to unhealthy diets.
• Over the last two decades, trade in agricultural products (excluding intra-EU flows) has more than tripled in value, to reach $1.33 trillion. The geography of global food trade flows has also shifted, primarily towards South–South trade, which now accounts for roughly a quarter of total agricultural trade flows. The nature of global trade has changed drastically, with traditional exports such as wheat and coffee growing slowly at around 2 per cent per year, while products such as palm oil, fruit juice, soft drinks and other processed products have grown at 8 per cent or more annually.
• This overall increase in trade in agricultural products raises questions about the growing utilization of resources, such as water or soil nutrients, that are embedded in those products through production and processing. Trade itself also causes negative environmental impacts, starting with greenhouse gas emissions associated with transport and storage. If the environmental cost associated with production and trade is not reflected in the final price of goods, trade may accelerate the depletion of resources or their unsustainable use.
• It is critical to ensure that trade policy options pursued by producing and consuming countries alike will support a transition to more sustainable and healthier food and land use systems. The first step in addressing trade-related food systems challenges must involve rebuilding trust among policy actors. There is a need for new spaces for informal dialogue among actors, and ‘soft’ governance mechanisms that can help rebuild consensus on the best ways forward. Meeting these challenges also requires an appreciation of the complex interactions between sectoral policies (e.g. on water, land, food, etc.) and their multiple interfaces with trade policies.
• Conditioning the use of subsidies on their sustainability and/or health impacts encourages the delivery of essential public goods in ways that are consistent with sustainability and health goals. A first step therefore is the removal of perverse incentives (e.g. subsidies encouraging the overuse of fertilizers or pesticides or the overproduction of certain commodities, as well as certain biofuels subsidies) and replacing them with market-correcting subsidies.
• Trade facilitation measures for fruits and vegetables that are aimed at easing transit at the border, by cutting unnecessary bureaucracy and reducing waiting times, can improve their availability, reduce costs and improve food quality and safety for consumers. Similarly, measures aimed at improving sustainable cold storage and upgrading value chains can support better diets and consumption by increasing the availability of fresh produce on markets, especially in developing countries.
• A global food stamps programme developed through the G20 and facilitated by the UN’s food agencies could address purchasing power imbalances and tackle malnutrition in developing countries. If carefully designed, such ‘safety net’ schemes can not only contribute to improving calorific intakes but also help deliver more balanced and healthier diets. Careful attention must be given to how such a scheme would work in practice, building on experience to date with similar initiatives.
• Integrating the notion of sustainable food and inputs trade in the post-2020 global biodiversity framework can help to deliver more sustainable and healthier food and land use systems. This could be achieved by likeminded countries introducing a set of goals or targets aimed at mitigating the role of trade in placing indirect pressure on biodiversity, and to encourage trade in biodiversity-based products including natural ingredients produced ethically and following sustainability principles and criteria.
• An SDG-oriented agenda for agricultural trade is needed. It could be formed by countries seeking to remove perverse incentives, guaranteeing a safe harbour for market-correcting measures, clarifying existing rules and establishing plurilateral negotiations among subsets of the WTO membership, or sectoral approaches, to address specific challenges.
• Greenhouse gas emissions resulting from trade need to be addressed. Governments could seek to achieve this through ensuring the carbon neutrality of existing and new trade deals, either by connecting carbon markets among contracting parties or by developing joint initiatives to tax international maritime and air transport emissions.

The ways in which land use and environmental policies intersect with natural resource sustainability and climate change was the focus of discussion in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program” featuring Charles Taylor, assistant professor of public policy at Harvard Kennedy School. The podcast is produced by the Harvard Environmental Economics Program.

 A recent study shows that the genetic diversity of the Gaur and Sambar are under threat in central India 

Last week, the Icelandic government rolled out several new environmental policies and proposals addressing climate change as part of the country's second COVID-19 economic stimulus package.

Imagine you have an important decision to make. Do you carefully consider the long-term implications of each possible option or do you act impulsively? Would you approach the decision-making process differently if the consequences stretched out to 30 or even 50 years?

Saltmarsh restoration can contribute to a range of ecosystem services but, according to new research, the effectiveness depends on previous land use. To optimise restoration, more research is needed on the effects of previous land disturbance on the delivery of ecosystem services and the relationships between physical, biogeochemical and ecological processes.

A new Spanish study has highlighted current developments in the tourism sector that have significant implications for water supply and demand, but are barely addressed in recent land use policies. The findings indicate that any tourist destination that is to follow the ???quality tourist??? model will have an increased water demand in domestic residential areas, which is one of the biggest threats to sustainable water management.

Wildfires in the Mediterranean region are a significant threat to human life and the natural environment and cause considerable economic damages. Recent research from Italy suggests that different types of land cover influence the timing of wildfires throughout the year and this knowledge can be used to improve fire risk assessment and prevention strategies.

The reduction in summer storms in the western Mediterranean could be partly caused by land use change on coasts and mountain slopes, a new study reports. This lack of storms causes water vapour to build up above the region and may lead to heavy rainfall and flooding in central Europe.

Estonian research has identified land use practices and agrochemical use as the main pressures that are causing a decline in pollinating insects in Europe, such as bees and butterflies. It calls for increased funds for agri-environment measures from the Common Agricultural Policy (CAP) to help tackle pollinator loss.

The costs and benefits of sustainable land management have been collated in a new review. Data from a global archive was analysed for the costs of sustainable practices and technologies and for land users’ perceptions of cost–benefit ratios. Most respondents had a positive view of the short-term cost-benefit ratio, and a strongly positive view of the long term. Low upfront costs, long-term planning and security of land tenure were identified as important factors to facilitate these practices.

Land cleared in the tropics loses nearly twice as much carbon and produces less than half the annual crop yield as land in temperate zones, according to researchers. Their analysis of the trade-off between crop production and the loss of carbon stored in vegetation highlights the need to target reforestation in the tropics.

A recent study has projected changes in the spread of malaria caused by climate change and climate variability in Africa by including the effect of variations in land use on local climate. It concludes that the risk of malaria epidemics is likely to shift from the north to the south of the Sahel, and to highland areas previously free of the disease.

Agricultural intensification can significantly affect soil ecosystems and the services they provide, new research suggests. Examining soils across Europe, the study demonstrates that high intensity arable land uses have lower diversity and biomass of soil organisms than lower intensity arable or permanent grassland, affecting the carbon and nitrogen cycles in the environment.

Floods are devastating natural hazards, which can cause loss of life and substantial damage to buildings and other infrastructure. Assessing future flood risk is complicated by the influence of climate change, land-use change and economic development in an area. A study on an Alpine valley suggests that land- use change and urbanisation will affect future flood risk by 2030 more than climate change, but risks can be reduced by adopting low-cost adaptation strategies, such as building restrictions in flood-prone areas and residents taking their own precautions against flooding.

The land use associated with food imports to Germany outweighs that of exported food, leaving the country with a 'land debt', new research suggests. However, reducing the amount of animal products in the diet and minimising food waste could enable the country to achieve a positive land balance, the researchers conclude.

A new study has developed a system to assess the potential of ecosystems to supply ecosystem services in the EU-25 plus Switzerland and Norway. It is one of the first to use historical and projected data on land use change at a continental scale to estimate the provision of ecosystem services and to assess possible trade-offs between them.

Researchers have developed a new framework to assess the impact of land use policies on sustainable development in developing countries. The framework integrates environmental, economic, social and institutional impacts through the use of multiple influences and indicators identified by a range of stakeholders.

Each person in the EU consumes the equivalent of 30% more global arable land than can be considered sustainable, according to a new study. As well as providing food for a growing population, the land is also increasingly used to grow biofuel crops.

Approximately 1000 km2 of agricultural or natural land is lost every year in the EU due to land-use change. When this occurs close to residential areas, it can lead to conflict with local people. This study explored the views of local people in Romania, and compared them to experts. The authors discuss similarities and differences, and say that participation, where both locals and experts communicate, is key to developing effective land use policies.

New research in the Netherlands indicates that spatial planning to manage flood risk, such as the elevation of residential areas and the exclusion of vulnerable land uses from flood-prone areas, is underused. Its use appears to depend on governmental requirements, previous experience of flooding and previous experience of using spatial planning as a mitigation strategy.

A new study has estimated the water consumption and land use for the production of 160 crops that constitute most of the world’s cropland. The results suggest that, collectively, wheat, rice, cotton, maize and sugar cane account for 49% of water scarcity and 42% of land resource stress caused by worldwide crop production.

A new Spanish study has highlighted current developments in the tourism sector that have significant implications for water supply and demand, but are barely addressed in recent land use policies. The findings indicate that any tourist destination that is to follow the ‘quality tourist’ model will have an increased water demand in domestic residential areas, which is one of the biggest threats to sustainable water management.

Spanish Basque Country, grasslands were found to supply the greatest amount of river water, followed by native woodlands, with exotic woodland plantations providing the least. Researchers also call for more comprehensive analyses of ecosystem services, including carbon sequestration and biodiversity, to inform land-use policy.

Research from Slovakia suggests that the total area of change in land cover, as well as land management practices, are more important in generating floods than the type of land cover change, such as deforestation.

Land use changes over the last century in the Mediterranean area may be sparking shifts in weather patterns locally, across Europe, and around the globe, suggests a new study. The findings bring to light new complexities that can be integrated into climate models and predictions.

New research indicates that successful integration of conservation into local land-use planning needs a combination of regulatory measures and community values. This could be encouraged by better education on conservation, and greater collaboration between neighbouring geographical areas.

The effects of changing agricultural practices on farmland birds are explored in a recently published study from Sweden. Overall abundance of 16 common species declined by 23% between 1994 and 2004, which may be partly caused by changes in land use, such as an increase in the amount of wheat cropland. However, effects vary between species, and some species increased or stayed stable in number.

Biodiversity scenarios are a useful tool to help policymakers predict how flora and fauna will likely respond to future environmental conditions. Although changes to land use are a major driver of biodiversity loss, scenarios focus overwhelmingly on climate change, a new study shows. The researchers say this imbalance makes scenarios less credible, and make recommendations for developing more plausible projections.

Agroforestry — managing trees alongside crop or animal-production systems — has been proposed as a means of protecting biodiversity and enhancing ecosystem service supply. A study bringing together evidence has confirmed that agroforestry does have an overall positive effect over conventional (separate) agriculture and forestry. Its environmental benefits, which should be considered in rural planning policy, include reduced nutrient run-off and soil erosion, and biodiversity protection.

Exposure to polluted soil can affect human health, but the risk may vary depending on the soil type. A recent study has shown that the differing amounts of cadmium and lead that can be dissolved in the human digestive system can be predicted for contaminated agricultural, urban and woody habitat soils using a model. Its authors suggest this is a useful method for assessing the risks of contaminated land.

Halving meat and dairy consumption in Europe could reduce agricultural greenhouse-gas emissions by up to 42% and nitrogen pollution by 40%, new research suggests. The amount of land needed to grow food for each EU citizen would fall from 0.23 to 0.17 hectares and the reduced intake of saturated fats and red meat could have substantial health benefits, the researchers conclude.

This study updates an earlier assessment of the past, current, and prospective situation for the Nation's land base. We describe area changes among major land uses on the U.S. land base for historical trends from 1982 to 2002 and projections out to 2062.

Changing patterns of land use are at the heart of many environmental concerns regarding U.S. forest lands. Of all the human impacts to forests, development is one of the most significant because of the severity and permanency of the change.

Sustaining farm and forest land has been an important goal in the United States because of the role these lands play in the livelihoods of rural residents while also providing desired open space benefits. However, land use policies to protect rural lands often involve a tension between balancing public interests regarding economic and open space goals with the private interests and property rights of farm and forest land owners.
