Microplastic pollution in soils is a recent environmental problem and the lack of knowledge about the impacts and the extent of the problem are raising questions and concerns among researchers and politicians. Using a normative simulation model, we assess the extent of microplastic pollution in German agricultural soils originating from the land ap...

Full-text available
Microplastic (MP) contamination in agricultural soils has recently gained significant attention in science and society. The continuous plastic waste generation and its low degradation rates indicate a cumulative effect of MP in the environment that calls for more research on the amounts and impacts of this contaminant. The most discussed agricultur...
Article
State-owned enterprises are companies in which government owns, directly or indirectly, more than 50% of the shares. Worldwide, states own 10% of the largest companies. In South Africa, state-owned enterprises play a significant role in the important sectors of mining, energy, communications, air and rail transport. Some state-owned entities loom...
Article
Full-text available
The COVID-19 pandemic has exacerbated gender-related structural inequalities and barriers in women’s healthcare access – a phenomenon similarly observed in past economic and health crises. Yet long-term, intersectoral and structural reforms are given low priority. G20 leaders have an opportunity to use COVID-19 recovery initiatives to build more ge...
Article
This paper offers a quantitative assessment of the impacts of the COVID-19 pandemic-induced lockdown and government fiscal plan, containing ‘green’ elements on the economy and the environment of South Africa. The analysis uses a dynamic computable general equilibrium model operationalised using a social accounting matrix coupled with a greenhouse g...

Little is known about the general equilibrium impact COVID-19 induces on different gender groups. This paper addresses the problem of relatively few general equilibrium studies focusing on gender impacts of COVID-19. The analysis uses a gendered Computable General Equilibrium model linked to a microsimulation model that analyses a mild and severe s...
Article
This paper constructs and uses a recursive dynamic general equilibrium model for South Africa to examine the economywide consequences of a continued deterioration in performance of state‐owned enterprises and rise in foreign interest rates. A decline in state‐owned enterprisesproductivity has substantial negative ramifications on the rest of the ec...

Full-text available
Microplastic pollution in soils is a recent challenge for environmental science and policy. Designing and implementing policies to mitigate microplastic emissions requires scientific data, which is rare because analytical methods to detect and quantify microplastics in soils are still under development. Using a normative emission model we simulate...

Full-text available
Microplastic sources and pathways in the environment with the focus on soil are highlighted. Since to date, little knowledge exists on the quantities of microplastic accumulating in soils and its impact, we used a spatial model to estimate the masses of microplastic entering the soil from the three main agricultural sources: Sewage sludge, compost...

Presentation
Full-text available
The topic of microplastic contamination in agricultural soils has recently gained attention in science and society. Experimental studies indicate that microplastic (i.e., plastic particles < 5mm in size) can have negative effects on soil organisms, but it is unknown if an impairment of ecologic functions happens at the actual concentration levels o...

Influential documents such as the synthesis reports produced by the Intergovernmental Panel on Climate Change (IPCC) in 2007 and 2014 and the Stern Review on the Economics of Climate Change in 2007 reignited a global effort to counter the effects of global warming and climate change. The United Nations has made climate change a focal point in all i...

We investigate the influence of weather on countries’ GDP and their main components of production, namely total factor productivity, capital stock, and employment. Our panel dataset includes annual observations on 103 countries for the period 1961–2010. We find that the main impacts of weather occur through temperature and drive the growth in GDP....

This special issue contributes to the natural resource economics literature by shining a light on the specific challenges and opportunities faced by developing countries that have recently become dependent on natural resources or are particularly exposed to climate change. It is composed of five studies on countries from all regions of the developi...
Article
Since the fall in world oil prices in June 2014, the economic and political settings for fossil fuel subsidy reforms have changed. As in many developing economies, in South Africa oil price subsidies are criticized as an inefficient policy instrument because they hamper economic growth, contradict objectives of climate change mitigation and mainly...
Article
This paper draws together quantitative methodologies from environmental and tourism economics to develop a framework for evaluating investments in cultural tourism. Indirect and induced benefits of investment in cultural tourism contribute to the overall returns on investment and not including these considerations can result in a nontrivial underva...

In the Dominican Republic, tourism represents a significant share of growth domestic product. Improving and increasing cultural heritage tourism opportunities offer potential for tourism product diversification which can expand the visitor base, increase tourism expenditure, and ultimately contribute to enhanced economic growth and development for...
Article
China's crop production sector faces severe water scarcity issues. Previous research has shown that effective water conservation policies exert strongly negative impacts on agricultural production and farmers' income, which make them politically unfeasible under Chinese conditions. To highlight ways out of this dilemma, the present study tests thre...
Article
In Northern and Central Europe, short-rotation coppices (SRC) have become a profitable agricultural production alternative, particularly for marginal fields with suitable groundwater levels. Furthermore, the replacement of fossil fuels by the wood chips produced in SRC contributes to the mitigation of greenhouse gases (GHGs). Due to heterogeneous reg...
Article
Agricultural production contributes 11% to the total German greenhouse gas (GHG) emissions. We compare the efficiency of three different land use based GHG abatement measures in combination and as separately applied measures: the production of short rotation coppices, of feedstocks for biomethane production, and peatland restoration. We evaluate th...

Due to their high protein content, soybeans are important feedstuffs in the European Union (EU). However, the cultivation of soybeans using genetically modified (GM) varieties in non-EU countries is increasing and the EU authorization of GM products takes longer than in other countries, leading to an asynchronous approval between the EU and non-EU...

Assessing the impact of climate change on agriculture is a new challenge for quantitative model-based policy analysis. The impact of climate change will vary strongly across regions depending on pre-existing climatic, agronomic, and political conditions. Most of the present modeling approaches, which aim to analyze the impact of global change on ag...

Both climate and agricultural policy changes are commonly seen as important drivers for agricultural production. In this study, scenarios of climate and political change were calculated for the Upper Danube catchment area using the regional optimization model ACRE. Two political scenarios were calculated for the year 2020. One scenario assumes the...
