14 pages, This study aimed to estimate the economic benefits of the mangrove ecosystem resulting from coastal rehabilitation efforts in the coastal area of Karawang Regency, West Java Province, Indonesia. The estimation results are crucial for convincing stakeholders, including the government, that the budget allocated for coastal rehabilitation will provide significant benefits for human well-being and the sustainability of coastal ecosystems. The study employed an economic valuation analysis method, focusing on the three areas most severely affected by coastal erosion in Karawang Regency. The results showed that the total annual economic benefit from mangrove planting as part of coastal rehabilitation in these areas amounted to IDR 4,257,468,324,946. These findings are intended to support efforts to achieve the Sustainable Development Goals (SDGs).
17 pages, Southern Australian farming systems operate predominantly under Mediterranean climatic conditions, which limit the choice of cover crops suitable for enhancement of ground cover and soil moisture retention, erosion control, atmospheric soil nitrogen (N) fixation, and weed suppression between cash crop rotations. Given that the successful establishment of cover crops is climate-driven and also influenced by edaphic factors such as soil pH and salinity, there has been increased interest by southern Australian producers in identifying potential cover crop species well adapted to specific Australian farming systems, which provide vital ecosystem services and sustainable economic benefits through the improvement of soil properties. This review summarises recent findings on cover crop inclusion in diverse farming systems in southern Australia, including continuous and mixed broadacre cropping as well as viticulture and horticulture systems, to identify opportunities and limitations related to their use. Cover crop inclusion in viticulture and pasture systems with lower moisture stress was observed to benefit the subsequent cash crop through enhanced production potential. Long-term, multi-site field experimentation incorporating summer cover crops in winter crop rotations showed that cover crops enhanced ground cover and soil water infiltration in some locations across southern Australia while sometimes increasing winter crop yield, suggesting that soil type and regional climatic conditions greatly influenced the delivery of multiple cover crop benefits. Collectively, these studies have suggested a need for longer-term field evaluations using multiple cover crop species and investigations of termination options under varying environmental and soil conditions to better quantify the legacy effects of cover crops.
