文摘The Dhofar region of Oman,renowned for its unique monsoon-influenced climate and substantial agricultural potential,faces significant challenges in achieving sustainable agricultural practices that balance productivity with environmental conservation.This review critically explores a range of sustainable agricultural methods currently im-plemented in the region,including organic farming,water conservation techniques such as drip irrigation and rainwater harvesting,agroforestry systems,crop rotation,and soil conservation measures like terracing and composting.These strategies aim to mitigate pressing environmental concerns such as water scarcity,soil erosion,and land degradation while enhancing crop yield and farm profitability.The review further examines the economic implications of these practices, evaluating their cost-effectiveness, potential for long-term returns, and influence on the growing market demandfor organic and eco-friendly products. Despite their benefits, the broader adoption of these sustainable approaches ishindered by several challenges, including limited access to advanced technologies, inadequate financial resources, lackof technical knowledge, and minimal awareness among local farmers. The article also assesses the role of governmentalpolicies, subsidies, and extension services in promoting the adoption of sustainable agriculture in Dhofar. Finally, it offersstrategic recommendations for future research, policy development, and capacity-building initiatives. This reviewemphasizes the urgent need for continued investment in sustainable solutions to ensure long-term agricultural resilienceand environmental sustainability in the region.
文摘This study focused on realizing Sustainable Development Goal(SDG)6 for inclusive clean water and sanitation;in particular Target 6.3,which aims to reduce untreated wastewater by 2030 while promoting circular wastewater reuse and recycling globally.The main objective was to assess the adequacy and efficiency of communal septic tank systems in informal settlements while helping local planners and authorities in their decision-making regarding Target 6.3.Quantitative and qualitative approaches were employed with secondary data from previous researchers,and primary data were collected from field surveys,observations,and interviews with members of the local community.The research was delimited to two village administrative divisions known as Rukun Warga(Village Administrative Division,RW):RW 7 and RW 8 of Lebak Siliwangi Kampung in Coblong District,Bandung,West Java,Indonesia.The findings were also compared with situations in other informal settlements in Brazil,Bangladesh,and Nairobi.The results indicated the inadequacy of communal septic tanks in informal settlements due to factors such as substandard system design,limited support and communication between authorities and residents,and the gap between septic tank availability and capacity vis-a-vis demand.Other limiting factors included limited land availability and irregular geomorphology,the latter of which affected the siting and operation of septic tanks due a lack of room for upgrades or expansion in response to continuous population growth.These findings illustrate the need to complement communal septic systems with flexible centralized or decentralized systems to achieve Target 6.3 of SDG 6.
