Abstract As a source of diffuse pollution, land use/land cover (LULC) can have profound impacts on water quality. Accordingly, the importance managing land‐water nexus is often emphasized in rhetoric Integrated Water Resources Management (IWRM). Several authors, however, cautioned that this need frequently overlooked practice. This partly because stakeholders and policymakers are not equipped with clear accessible information about LULC resources consequent to manage both sustainable coordinated manner. The result persistent sectoral fragmentation management these two resources, concomitant failure develop proactive data‐driven catchment strategies. Aimed principally at academics, researchers, policymakers, article argues there an urgent need, especially developing countries such as South Africa, for ongoing research into resources. More particularly, accurate models will provide motivation, knowledge, understanding necessary effective, informed, A do so, illustrated by current situation may dire socioeconomic ecological consequences.

Assessing the potential impacts of a revised set of on-farm nutrient and sediment ‘basic’ control measures for reducing agricultural diffuse pollution across England

The need for improved abatement of agricultural diffuse water pollution represents cause concern throughout the world. A critical aspect in design on-farm intervention programmes concerns potential technical cost-effectiveness packages control measures. European Union (EU) Water Framework Directive (WFD) calls Programmes Measures (PoMs) to protect freshwater environments and these comprise 'basic' (mandatory) 'supplementary' (incentivised) options. Recent work has used measure review, elicitation stakeholder attitudes a process-based modelling framework identify new alternative set sector measures nutrient sediment across England. Following an initial scientific review 708 measures, 90 were identified further consideration at industry workshop 63 had support.

Eutrophication of lakes and reservoirs is a major water quality problem that poses significant environmental, economic social threats around the world. Monitoring managing to prevent or limit eutrophication, therefore, has value. The literature been reviewed study ecological engineering management methods have can be applied improve quality. Ecological potential utilized design operation through monitoring active biological, chemical physical components. Phosphorus concentrations reduced by effective sustainable practices
