Despite the excitement around the nexus between land, energy and water resource systems, policies enacted to govern and use these resources are still formulated in isolation, without considering the interdependencies. Using a Ugandan case study, we highlight the impact that one policy change in the energy system will have on other resource systems. We focus on deforestation, long term electricity supply planning, crop production, water consumption, land-use change and climate impacting greenhouse gas (GHG) trajectories. In this study, an open-source integrated modelling framework is used to map the ripple effects of a policy change related to reducing biomass consumption. We find that, despite the reduction in deforestation of woodlands and forests, the GHG emissions in the power sector are expected to increase in between 2040–2050, owing to higher fossil fuel usage. This policy change is also likely to increase the cost of electricity generation, which in turn affects the agricu...

土地，能源和水资源管理及其对温室气体排放，电力供应和粮食生产的影响-乌干达案例研究的见解

尽管土地，能源和水资源系统之间的联系令人兴奋，但制定的用于管理和使用这些资源的政策仍是孤立制定的，没有考虑相互依赖的问题。通过乌干达的案例研究，我们强调了能源系统的一项政策变更将对其他资源系统产生的影响。我们专注于森林砍伐，长期电力供应计划，作物生产，水消耗，土地用途变化以及气候影响温室气体（GHG）的轨迹。在这项研究中，使用开源集成建模框架来绘制与减少生物量消耗相关的政策变更的连锁反应。我们发现，尽管减少了林地和森林的砍伐森林，但预计2040-2050年期间电力行业的温室气体排放量仍将增加，由于化石燃料使用量增加。这项政策变化也可能会增加发电成本，进而影响农业生产。
