    Trees inside one-heactare plots in Bolgatanga Municipal and Bongo districts were measured and identified. Selection of the plots was done randomly trying to spread them over the different parts of the region and represent the main land use types. Allometric measurements of trees - DBH - Crown diameter - Height Specie identification - Local name - Botanical name - English name Location - GPS record

    The data set contains registered land leases obtained by mostly private individuals in the Upper West Region from 1976 to 2013. The data covers the sections or communities and districts where the land transactions took place.

    Control of corruption captures perceptions of the extent to which public power is exercised for private gain, including both petty and grand forms of corruption, as well as "capture" of the state by elites and private interests. This table lists the individual variables from each data source used to construct this measure in the Worldwide Governance Indicators

    Economies are ranked on their ease of doing business, from 1–190. A high ease of doing business ranking means the regulatory environment is more conducive to the starting and operation of a local firm. The rankings are determined by sorting the aggregate distance to frontier scores on 10 topics, each consisting of several indicators, giving equal weight to each topic. The rankings for all economies are benchmarked to June 2017.

    Alluvial gold mining generates a vast amount of extractive waste that completely covers the natural soil, destroys riparian ecosystems, and negatively impacts river beds and valleys. Since 2002, a gold mining company has striven to create agroforestry plots in the waste deposits as a post-mining management approach, where agricultural crops and livestock are combined to complement reforestation in the area. This research aims at supporting reclamation of waste deposits by providing a comprehensive understanding of processes to manage the transition of nutrient-poor and acidic deposition sites towards productive agroforestry-based systems. Major components of this research comprise (i) an analysis of environmental and social challenges of the gold mining sector in Colombia, and its potential opportunities to add value to affected communities, (ii) an assessment of management practices and decision-making processes of the farmers working on reclamation areas, (iii) an analysis of the sources of variability of waste deposits from the perspective of soil development and vegetation succession, (iv) an analysis of spatial variability of the physicochemical properties of waste deposits with a spatially explicit management scheme, and (v) an assessment of vegetation recovery in terms of biomass and plant community composition. Farmers who are currently working on areas undergoing reclamation rely mostly on their own local knowledge to respond to the challenges that the heavily disturbed conditions of the area pose to crop establishment. Therefore, increasing their awareness of the inherent heterogeneity of their fields, as well as the interdependencies between management practices and improvement of soil fertility, may increase the productivity of their farms. The analysis of sources of variability of the waste deposits generated by alluvial gold mining revealed that these deposits are primarily influenced by the parent material of the alluvial gold deposits and by the technology used for gold mining (bucket or suction dredges), which define the type of deposit formed (gravel or sand). Waste deposits can provide essential functions for rural areas such as woody biomass production and crop establishment if deposits are managed according to a specific purpose, and crop selection for each deposit is done based on physicochemical and structural soil properties. This finding is echoed by the spatial assessment of vegetation reestablishment through the combination of remote sensing with machine-learning techniques that show a high spatial variability of textural properties and nutrient contents of the deposits. A management approach is proposed with the use of delineated management zones, which can lead to an overall increased productivity by developing strategies suitable to the characteristics of each field and its potential uses.

    Palm oil constitutes approximately one-third of the 130 million tonnes of major vegetable oils and fats consumed annually worldwide. The use of bio-based materials in palm oil production and the potential to achieve a zero-waste production process motivated this study of the potential of the Malaysian palm oil industry participating in sustainable bioeconomy. Thus, assessment of policies on chain upgrading and bioeconomy programme is discussed in this study. In order to assess the productivity and the efficiency of oil palm plantations, field research was conducted in two regions in Malaysia: Johor in Peninsular Malaysia as an example of a long-term production area and Sabah in Borneo, a newly established oil producing site. A gross margin analysis was also conducted within a global value chain framework. The growers were disaggregated into three groups according to scale (smallholders, medium-sized growers, and large estates). In Johor, smallholders earned lower gross margins than large scale growers as a result of the long-term impacts of this industry. However, in Sabah, where the palm oil industry is a relatively recent development, there was an inverse relationship between farm size and income. Thus, a cost benefit analysis (CBA) was applied to evaluate the opportunity and the external costs of producing palm oil. The CBA also considers environmental factors, such as land-use changes, carbon emissions from fertilizers, pesticides, transportation for oil palm fruits, and methane and carbon emissions from extraction mills (which have frequently drawn concerns from critics of palm oil). A 25-year period (the length of a commercial cycle of the palm oil industry) and real interest rate scenarios (1–8 %) were adopted for the analysis. Based on the findings, the most productive plantations under the Federal Land Development Authority (FELDA) scheme, which has been a key institutional actor in the development of the Malaysian palm oil industry, earned a Net Present Value of RM84,980 (US$26,776) per hectare, earning more than the less productive plantations under the same scheme (approximately 293% higher) in 2010. Moreover, the external costs of converting forests to oil palm plantations were higher than that of repurposing existing rubber or cocoa plantations for oil palm plantation (which also stores less carbon). Comparing the two study regions, it was found that the small- and large-scale growers in Johor (the pioneer region of the industry) performed better than their Sabahan counterparts (where the palm oil industry is a more recent development) in terms of net present value (NPV) per hectare. However, this was not the case for medium-sized growers. In addition, the mills in Johor also performed better than those in Sabah in terms of NPV per hectare. To examine policy options that could be adopted to turn the Malaysian palm oil industry into a bioeconomy, two biofuel policies adopted by industrialised countries were reviewed, namely German rapeseed biodiesel and US corn ethanol policy. These international policies could serve as examples for the Malaysian government to improve their policy strategies for the Malaysian palm oil biofuel industry. The mixed experiences of the Malaysian policies for accelerating the development of the palm oil industry can be important lessons for other palm oil producing countries.

    The State Legitimacy Indicator considers the representativeness and openness of government and its relationship with its citizenry. The Indicator looks at the population’s level of confidence in state institutions and processes, and assesses the effects where that confidence is absent, manifested through mass public demonstrations, sustained civil disobedience, or the rise of armed insurgencies. Though the State Legitimacy indicator does not necessarily make a judgment on democratic governance, it does consider the integrity of elections where they take place (such as flawed or boycotted elections), the nature of political transitions, and where there is an absence of democratic elections, the degree to which the government is representative of the population of which it governs. The Indicator takes into account openness of government, specifically the openness of ruling elites to transparency, accountability and political representation, or conversely the levels of corruption, profiteering, and marginalizing, persecuting, or otherwise excluding opposition groups. The Indicator also considers the ability of a state to exercise basic functions that infer a population’s confidence in its government and institutions, such as through the ability to collect taxes.
