When the country decided to adopt a policy on liquid biofuel, it engaged Tansheq to carry out a strategic environmental and social assessment (SESA) for liquid biofuel development.
Tansheq conducted SESA to cover the whole set of activities in biofuel industry which includes:
- Biofuels Feedstock Production
- Biofuels Processing
- Biofuel Marketing and Trade
As a very minimum, the SESA process involves: predicting the cumulative environmental and social impacts of a strategic action; and using those predictions in decisionmaking.
Tansheq used a Multicriteria Analysis to assess various alternatives of liquid bioenergy development. The alternatives were analyzed based on sustainability criteria of Green House Gas Emission, Biodiversity, Land Productivity & Resource Use Efficiency, Soil (productive capacity and soil erosion), Water (utilization and pollution), Food Security, Occupational Health and Safety, HIV/AIDS, Land Tenure; and Gender Conditions and child labour. In some scenario, Technology and Socioeconomic Development were among used criteria. The analysis of alternatives considered both positive and negative impacts and it used the yardsticks of environmental, socio–economic and cultural integrity. Using the Multi-Criteria Analysis (MCA) technique, the following alternatives were analyzed:
- Alternative 0: Business As Usual;
- Alternative 1: Plantation Model;
- Alternative 2: Smallholder Model;
- Alternative 3: Hybrid Model;
- Alternative 4: Hybrid Model Edible Feedstock;
- Alternative 5: Hybrid Model Nonedible Feedstock;
- Alternative 6: Hybrid Model Second Generation;
- Alternative 7: Hybrid Model Edible Feedstock in Arable land;
- Alternative 8: Hybrid Model Edible Feedstock in Marginal Land;
- Alternative 9: Hybrid Model Nonedible Feedstock in Arable land; and
- Alternative 10: Hybrid Model Nonedible Feedstock in Marginal Land.
Decision Tree Analysis, a structure that helps analyze risks and rewards involved with potentials for alternatives, was used to find out which alternatives to be further considered.
