‘Complex crisis’ and the rise of collaborative natural resource governance: institutional trajectory of a wildlife governance experience in Ghana

Natural resource governance is underpinned by institutions which evolve ‘circumstantially’ over time. An attempt at understanding the contemporary institutions and governance structure of a resource requires an in-depth ethnographic enquiry. Adapting a four-phase institutional analysis framework, this study discusses the evolution and adaptation of wildlife governance structures and institutions using the unique experience of Boabeng–Fiema Monkey Sanctuary in Ghana. The study adopted a transdisciplinary research approach which was participatory and consultative. The key observations are that: wildlife institutions have gone through three main evolutionary phases, a pre-collaborative phase, which was exclusively underpinned by informal institutions; a critical juncture stage, where contextual challenges led to an adaptive response; the third and contemporary phase is a collaborative governance regime, where the erstwhile informal institutions have been complemented by formal state structures and institutions to synergistically enhance viability of the wildlife species. In spite of the problems posed to community members by the monkeys (wildlife), the study still observes a cordial human–wildlife relationship. Based on the study outcomes, we derive four key conclusions which have implications for institutionalism and natural resource governance.     

What are distributed lag models of particulate matter air pollution estimating when there are populations of frail individuals?

The three-state (healthy, frail, and dead) population model is commonly used in time-series investigations of mortality displacement and particulate matter air pollution (PM). In this paper, the author proposes a new population model, called the mixture population model, that by allowing PM to have differential effects on individuals in the population, extends the population models currently used in investigations of mortality displacement. Using this new model, the properties of distributed lag models (DLM) of PM are investigated. In particular, the author derives a relationship between the parameters of the proposed population model and the estimates obtained from a DLM fitted to mortality arising from the model. This relationship provides insight into the interrelationships between the size of the frail population, the number of lags of PM included in a DLM and the proportion of the effect of PM on the healthy population that is estimable. The relationship will guide and contextualize future investigations by providing researchers with the knowledge to assess the consequences of the number of lags of PM included in a DLM in terms of what they can plausibly infer about the effect of PM on mortality based on this choice of lag.     

Model sustainability in DSS design and scenario formulation: what are the right scenarios?

A concept of the integrated approach in designing multidisciplinary decision support systems (DSS) based on agricultural scenarios for sustainable catchment management is discussed. A principle of holism underlying the integrated approach to DSS design is formulated. For a model to be viable and sustainable, it should be based on scenarios that are plausible and highly typical from the point of view of those 'doing' agriculture. Problems concerning principles of scenario formulation within the integrated approach are considered. A notion of 'prototype' scenarios based on 'joint venture' of modellers and stakeholders is proposed.     

Pulp industry and environment in Indonesia: is there sustainable future?

The global demand for wood is set to increase significantly over the next two decades. The growth is to be particularly pronounced in the Asia Pacific, and timber plantations are expected to be a major source of wood fiber. Indonesia is taking steps to meet the global demand for wood by expanding its pulp production and timber plantations. However, there are concerns about the environmental trade-offs of this expansion. The pulp sector continues to rely on natural forests for timber. The size and productivity of timber plantations are uncertain because of unreliable data. The employment and poverty alleviation potential of the pulp sector are overstated. The pulp sector continues to attract large-scale foreign capital due to high returns on undervalued timber from natural forest. However, environmentally and socially, it is a high-risk investment. The pulp sector in Indonesia can be environmentally sustainable and economically profitable, but the conversion of natural forest must be stopped; the use of non-forest land for plantations must be maximized; and smallholder tree-growing schemes must be made simpler and more attractive. Careful revision of the pulp growth targets and greater investor due diligence are needed to ensure a more sustainable future.

Is there a density compensation effect in plant communities of anthropogenic habitats?

The occurrence of density compensation effect (DCE) has been estimated in areas occupied by synanthropic communities in the Western Caucasus. The density of dominant plant species has been estimated from their coverage, and that of subordinate species, from their frequency in 0.5-m² squares within 15 (16)-m² plots, using natural and seminatural communities as a reference standard. The factual material has been analyzed by the method of numerical experiments. The results show that the transformation of natural habitats into anthropogenic ones has led to a decrease in the species diversity of plant communities, but without causing a widespread occurrence of DCE. It is hypothesized that relatively high average values of species frequency in low-diversity synanthropic communities are more likely accounted for by random rather than compensatory processes.     

Prompt detection of alpha particles from 210Po: another clue to the origin of rock varnish?

Alpha particles have been measured coming from the surfaces of rocks covered with dark red-brown rock varnish, as well as rocks that appear to have little, if any, varnish. A pronounced peak at 5.3 MeV indicates the presence of 210Po, a short-lived natural-radioactive element. Surface activities for 33 samples range from 0.008 Bq/cm2 to 0.065 Bq/cm2. It is estimated that this nuclide is concentrated 10(11) times in these paper-thin coatings above its concentration in ground-level air. Gamma rays from the decay of 137Cs, a product of testing nuclear weapons some 50 years ago, were also detected. Analysis of samples of varnish stripped from the rock revealed traces of 239,240Pu and 238Pu. The presence of all of these isotopes strongly supports the theory that varnish films derive their building blocks from the atmosphere and, with time, all rocks in arid environments will become coated.     

Integrated climate governance in regions? Assessing Catalonia’s performance using the ‘climate learning ladder’

While developing climate change policies, regional governments and agents may have different purposes, follow different strategies, and use different appraisal procedures than those of national governments or other regions within the same countries. Climate change adds an additional source of problematisation to the functioning of traditional nation-states structures, not only at the international level but also with regard to their relations with sub-national agencies. This paper tests this hypothesis by analysing the emergence of climate strategies and capacities in region of Catalonia, north-east Spain, through the use of a novel integrated assessment tool called the ‘climate learning ladder’ that looks at four main dimensions: (1) how perceptions on climate change have evolved in this region since the beginning of the 1990s, (2) what type of incentives or systems of sanctions have triggered climate action, (3) what specific options are available or have been developed, and (4) what new institutional arrangements have been put in place during this time. Results indicate that although in Catalonia distinctive climate appraising processes have been tried, new measures have been implemented and new institutions have been created, not much of a distinctive progress regarding Integrated Climate Governance (ICG) has been achieved. Furthermore, this research shows that so far the main incentives which triggered climate action and innovation have been largely exogenous to the region.     

Study of the Optimization and Adjustment ofthe IndustrialStructure Subjected to Water Resource in the Drainage Area of the Yellow River

Since the 1990s, the Yellow River stream has been temporarily interrupted for several years, which affects the development of society, the economy and human life, limits the economic potential of the drainage areas, and especially causes great harm to regions on the lower reaches. Based on the analysis of the relationship between the development of society and economy and water scarcity, the author thinks it is necessary to optimize and adjust the industrial structure that has extravagantly consumed enormous amounts of water, and to develop ecological agriculture, industry and tourism which are balanced with the ecological environment. Finally, the author puts forward several pieces of advice and countermeasures about how to build the economic systems by which water can be used economically.     

Is there Really Spare Land? A Critique of Estimates of Available Cultivable Land in Developing Countries

Five assessments covering less-developed countries have identified a land balance, available for future cultivation, using the approach of inventory and difference: assessment of the area cultivable, and subtraction of the area presently cultivated. All arrive at a balance of 1600–1900Mha, about twice the present cultivated area. The supposed existence of this spare land is widely quoted in forecasts of capacity to meet the food requirements for future population increase. It is argued here that these estimates greatly exaggerate the land available, by over-estimating cultivable land, under-estimating present cultivation, and failing to take sufficient account of other essential uses for land. Personal observation suggests that the true remaining balance of cultivable land is very much smaller, in some regions virtually zero. An order-of-magnitude estimate reaches the conclusion that in a representative area with an estimated land balance of 50%, the realistic area is some 3–25% of the cultivable land. This speculation could be tested by directly attempting to find such land in areas where it is supposed to exist. The impression given by current estimates, that a reserve of spare land exists, is misleading to world leaders and policy-makers.     

Are the residents of former Yugoslavia still exposed to elevated PCB levels due to the Balkan wars? Part 1: Air sampling in Croatia, Serbia, Bosnia and Herzegovina

Persistent organic pollutants (POPs) spilled into the environment as a result of damaged industrial and military targets, natural resources, and infrastructure during the Balkan wars still pose a problem several years later. The aim of this project was to investigate an extent to which the residents of former Yugoslavia are exposed to elevated levels of POPs as a consequence of the wars. The atmospheric as well as the soil levels of PCBs, OCPs and PAHs were determined in Croatia, Serbia, Bosnia and Herzegovina during five high volume air sampling campaigns in 2003 and 2004. A considerable contamination of several sites was detected (PCB concentrations in the atmosphere ranged between 67 pg m(-3) and 40 ng m(-3) for the sum of 7 indicator congeners) and the levels are reported in this article.     

Solar photovoltaic investments and economic growth in EU: Are we able to evaluate the nexus?

A core question in energy economics may be stated as follows: Is the cost–benefit analysis being correctly applied when we encourage investments in renewables, as an alternative to the traditional energy sources? The relationship between energy consumption and economic growth has been extensively treated within economics literature. Yet, literature on the nexus between specific energy sources and GDP is almost inexistent. In this article, we intend to explore the relationship between a certain type of renewable generation technology (solar PV) and GDP. The present and above all the planned energy mix might differ widely from one country to another. Thus, the analysis by source of energy generation becomes a helpful instrument for policy-making. Using a fixed effects panel data methodology and a sample of eighteen EU countries, we find that a 1 % increase in solar PV installed capacity and in electricity production from renewable sources has a positive impact on GDP of 0.0248 and 0.0061 %, respectively. We also conclude that a 1 % growth on greenhouse gas emissions positively affects GDP by 0.3106 %. Further evidence reveals that, in terms of country-specific analysis, Germany, France, Italy and the UK have the most significant estimations for fixed effects. In fact, Germany is a solar PV technology producer, France has a very active nuclear sector, with little pressure for both renewables development and CO₂ reductions, Italy had in this period a strong governmental support to this sector, and the UK has a strong connection between the solar PV and the industry sectors.     

Exploring the Adaptation-mitigation Relationship: Does Information on the Costs of Adapting to Climate Change Influence Support for Mitigation?

Can information about adaptation costs influence citizens’ willingness to support climate change mitigation? Some scholars are concerned that policy discussions on adaptation might present climate change as a more manageable problem, and therefore crowd out mitigation efforts. On the other hand, providing information on adaptation costs may sensitize citizens to these costs, thereby increasing their willingness to support mitigation. To assess these conflicting predictions, we fielded a web-based survey experiment using a sample of 2,000 US-based respondents. We presented the respondents with a hypothetical newspaper article regarding a proposed gasoline tax (a mitigation strategy) and measured the support for this proposal across different treatment groups. In the control group, the respondents were told that failure to mitigate climate change could result in a potentially catastrophic outcome, whereas in each of the treatment groups the respondents were provided with information concerning possible adaptation costs. The respondents were then asked about their willingness to support a gasoline tax. Our key finding is that the provision of information about adaptation costs leads to a small increase in the respondents’ willingness to support mitigation efforts. Furthermore, we find that this effect becomes larger when the information regarding adaptation costs is made more specific.     

Once there was a river: a benefit–cost analysis of rehabilitation of the Jordan River

The Jordan River is among the world’s most famous and culturally and historically significant waterways. The lower stretch of the river, however, has been a victim of development in a water scarce region, with current flows less than 5 % of historical levels. Furthermore, as it functions as an international border in a region of conflict, access to the river and its potential as a tourist attraction has been limited. Recently, there have been numerous calls for rehabilitation of the river. This study presents a first estimate of the economic benefits of such rehabilitation and compares them to the estimated costs. Identical contingent valuation method surveys were administered in Israel, Jordan, and the Palestinian Authority. Evidence from this study shows that, despite the large opportunity costs of increasing environmental flows, rehabilitation of the lower Jordan would produce positive net economic benefits. This is true even though the study estimated only the benefits to local populations, and not to international tourists or those outside the region. Net benefits are maximized when taking a regional, as opposed to strictly national, approach.
