- Today several nations utilise risk based approaches in military planning. However, the discussion on limitations with the approaches in regard to aspects such as uncertainties, the nature of the threat and risk to civilians is limited.The aim of this work is to identify important challenges when applying risk based approaches to military activity. This article discusses risk based approaches in general and their military applications. Five generic quality requirements on risk analysis are presented from research in risk philosophy. Two military application areas for risk analysis: military intelligence, and risk management in legal assessments are analysed in relation to the presented quality requirements on risk analysis.From the analysis it is clear that risk analysis is an integral part of the decision-making analysis and cannot be separated in time, space or organisationally from the decision-making process in general. Defining the scenario to analyse, including the time span, is a central task in risk analysis and will affect every aspect of the risk estimation. Therefore, the principles for scenario definition must be communicated and continuously updated throughout the organisation. Handling the uncertainties throughout the process is also important, especially if the aim is a resilient military system.

- In his 2018 Stockholm prize winner lecture, Goldstein highlighted the need for problem-oriented policing (POP) to be not only effective but also fair. Contributing to the development of POP, this study examines how a wider perspective on problem-solving generally, and scoping in particular, can be adopted to address some of the growing challenges in 21st century policing. We demonstrate that the concept of ‘problem’ was too narrowly defined and that, as a result, many problem-solving models found in criminology are ill-structured to minimize the negative side-effects of interventions and deliver broader benefits. Problem-solving concepts and models are compared across disciplines and recommendations are made to improve POP, drawing on examples in architecture, conservation science, industrial ecology and ethics.

- Brazil is home to the largest tracts of tropical vegetation in the world, harbouring high levels of biodiversity and carbon. Several biomass maps have been produced for Brazil, using different approaches and methods, and for different purposes. These maps have been used to estimate historic, recent, and future carbon emissions from land use change (LUC). It can be difficult to determine which map to use for what purpose. The implications of using an unsuitable map can be significant, since the maps have large differences, both in terms of total carbon storage and its spatial distribution. This paper presents comparisons of Brazil’s new ‘official’ carbon map; that is, the map used in the third national communication to the UNFCCC in 2016, with the former official map, and four carbon maps from the scientific literature. General strengths and weaknesses of the different maps are identified, including their suitability for different types of studies. No carbon map was found suitable for studies concerned with existing land use/cover (LULC) and LUC outside of existing forests, partly because they do not represent the current LULC sufficiently well, and partly because they generally overestimate carbon values for agricultural land. A new map of aboveground carbon is presented, which was created based on data from existing maps and an up- to-date LULC map. This new map reflects current LULC, has high accuracy and resolution (50 m), and a national coverage. It can be a useful alternative for scientific studies and policy initiatives concerned with existing LULC and LUC outside of existing forests, especially at local scales when high resolution is necessary, and/or outside the Amazon biome. We identify five ongoing climate policy initiatives in Brazil that can benefit from using this map.

- Brazil is one of the major contributors to land-use change emissions, mostly driven by agricultural expansion for food, feed and bioenergy feedstock. Policies to avoid deforestation related to private commitments, economic incentives, and other support schemes are expected to improve the effectiveness of current command and control mechanisms increasingly. However, until recently, land tenure was unknown for much of the Brazilian territory, which has undermined the governance of native vegetation and challenged support and incentive mechanisms for avoiding deforestation. We assess the total extent of public governance mechanisms protecting aboveground carbon (AGC) stocks. We constructed a land tenure dataset for the entire nation and modeled the effects and uncertainties of major land-use acts on protecting AGC stocks. Roughly 70% of the AGC stock in Brazil is estimated to be under legal protection, and an additional 20% is expected to be protected after areas in the Amazon with currently undesignated land undergo a tenure regularization. About 30% of the AGC stock is on private land, of which roughly two-thirds are protected. The Cerrado, Amazon and Caatinga biomes hold about 40%, 30% and 20% of the unprotected AGC, respectively. Effective conservation of protected and unprotected carbon will depend on successful implementation of the Forest Act, and regularization of land tenure in the Amazon. Policy development that prioritizes unprotected AGC stocks is warranted to promote conservation of native vegetation beyond the legal requirements. However, different biomes and land tenure structures may require different policy settings considering local and regional specifics. Finally, the fate of current AGC stocks relies upon effective implementation of command and control mechanisms, considering that unprotected AGC in native vegetation on private land only accounts for 6.5% of the total AGC stock.

Potential increase of legal deforestation in Brazilian Amazon after Forest Act revision

Tidskriftsartikel (refereegranskat)abstract
- The Brazilian Amazon rainforest is protected largely by command and control regulation of public and private land. The Brazilian Forest Act requires private landholders within the Amazon to set aside 80% of their land as legal reserves for nature protection, but this requirement can be reduced to 50% if more than 65% of a state’s territory is protected public land (for example, public conservation units and indigenous reserves). In the ongoing land designation process in Brazil, some Amazonian states may cross this 65% threshold. We assess the potential reduction in the legal reserve requirement from 80% to 50%, through spatially explicit modelling of scenarios concerning land tenure consolidation, employing up-to-date databases on land ownership. Depending on the outcome of land designation processes and political priorities, some 6.5–15.4 million hectares of private land previously protected as legal reserves may become available for legal deforestation. While protection of public land is crucial for safeguarding the Amazon, revisions of federal and state legislation may be needed to avoid the further extension of protected public land triggering increased legal deforestation on private lands. Zero-deforestation commitments and other initiatives may mitigate impacts in the absence of such revision.
