High population pressure, inappropriate agricultural policies, improper land-use planning, over-dependency on agriculture as source of livelihood and extreme dependence on natural resources are inducing deforestation, overgrazing, expansion of agriculture to marginal lands and steep slopes, declining agricultural productivity and resource-use conflicts in many parts of Blue Nile. Increased land degradation from poor agricultural practices and erosion results in increased siltation and the reduced water quality in the river basin. The rainfall, runoff and sediment are highly variable both in time and space. Poor water and land management upstream severely affect runoff characteristics and the quality of water reaching downstream. The result is a downward spiral of poverty and food insecurity for millions of people both within the upper catchment and downstream across international borders. Quantification of the erosion, sedimentation processes and evaluation of impacts of interventions are difficult tasks. This paper schematizes the Blue Nile Basin (BNB) at various spatial levels as micro watershed, watershed, sub-basin to basin. It considers a particular watershed to model runoff, sediment and impact of watershed intervention. The result shows that runoff can be reasonably simulated with calibration of R2=0.87 and validation of result of 0.82, and comparable sediment modelling results. The study also demonstrates, by undertaking spatial analysis using topographic, soil and land use parameters it is possible to identify the high sediment risk sub-watersheds. Impact of typical watershed intervention using various widths of vegetative filter and application on high erosion risk watersheds show reduction of sediment yield from 52% to 74%

This research investigates farm households' adaptations to climate change-driven monsoon floods in the rural district of Nowshera, Pakistan. Some households in these flood-affected communities have undertaken autonomous adaptations to flooding. We surveyed five hundred farm households from both flood-affected and unaffected villages to investigate the factors driving the uptake of the following autonomous flood adaptations: plinth elevation, grain storage, participation in communal flood preparations and the creation of edge-of-field tree lined shelterbelts. We used both binary and multivariate probit regressions to investigate the correlation across adaptation options. Empirical results suggest that access to agricultural extension services, off-farm work opportunities, past duration of standing floodwaters, farm to river distance, receiving post-flooding support and tribal diversity are the main drivers of flood adaptations. Moreover, we report the complementary uptake of adaptations in pairs. Given the prediction of climate change-driven flooding in the Hindu Kush, we recommend cost-effective policies that increase the resilience of vulnerable agricultural-dependent rural communities. In addition, we report that respondents perceived a change in weather towards hotter and dryer weather over the last ten years.

Everyday ingenuities have gained hegemony in urban governance scholarship in the Global South, especially regarding the informal settlements of sub-Saharan Africa, where public water services are limited. Within the global commitment to sustainability, through the Sustainable Development Goals (SDGs), this article explores how non-state actors (water service providers) develop and sustain water infrastructure (provide, manage water systems for continued availability) in the informal settlements, through the lens of the everyday ingenuities and governance for sustainability framework, and a qualitative research approach. The study realized the involvement of individuals and group of actors in water infrastructure governance. The actors self-mobilized resources and develop low-cost water infrastructure systems. The actors engaged in a gamut of actions, transactions, clientelist (broker and clients’ relationships), and interactions (buying and selling of water, networking, production, cooperation, partnerships) to manage water infrastructure, the practices were guided by unwritten rules and regulations, and not independent of state actors’ interactions, but formed and developed through the relations between state and non-state water service providers. The findings suggest that water infrastructures in the informal settlements are developed and sustained through the everyday act of inventing, repetitive self-actions, ordering and disordering of the rules and mechanisms, among the inter-depending actors (producers and resellers of water), and their interactional relationship with the state water utility provider (DAWASA).

Water scarcity in arid and semi-arid regions represents a significant obstruction to social and economic development. Also, flood hazards affect the life of many people in these areas. This study aims to develop a new model for integrated management of surface water and groundwater, which involves rainwater harvesting and recharge to groundwater aquifers. Integrated hydrological models, including geographic information system (GIS), watershed modelling system (WMS) and groundwater modelling system (GMS) were used. This research provides an integrated vision for exploiting the rainwater in Wadi Watier, South Sinai, Egypt and shows new insights on how to protect these areas from flood risks and store water to solve the water scarcity in this region. Based on physical properties of sub-basins and soil properties, fourteen dams were suggested and designed to protect the study area from flood risks; five dams were used for storage and nine dams for groundwater recharge. The results showed that the dams could collect about 160.72 million m3 of rainwater which can be stored or recharged into groundwater aquifers. This will increase the national income and provide stability for residents in these areas that suffer from water shortage. Decision-makers can use these models for sustainable flood management in similar areas.

The Indus River System is a major source of life in Pakistan. A vast array of Pakistan's agricultural and domestic consumption needs are critically dependent on the Indus River System. The Indus River contributes towards 25% of the country's gross domestic product, providing water for almost 90% of the food production in Pakistan. Linked to the water security issues, Pakistan is potentially at risk of facing a severe food shortage in the near future. The World Bank report of 2020–2021 estimates that the water shortage will increase to 32% by 2025, which will result in a food shortage of almost 70 million tons. Water shortage could also result in confrontation between the provinces as river sharing has always been a source of problem for Pakistan. According to recent estimates, siltation and climate change will reduce the water storage capacity by 2025 to almost 30%. As for the per capita water storage capacity in Pakistan, it is about 150 m3, which is quite meagre in comparison with that in other countries. Irrigated agriculture will soon be adversely affected due to the reduced surface water supplies and the consequent increase in groundwater abstraction. To make matters worse, over the past decades, a great deal of distrust has developed among the provinces of Pakistan regarding the water distribution issue, and the successive federal governments have failed to formulate a cohesive inter-provincial National Water Policy. Along with the shortages and increasing demand for water, administrative corruption also plagues the water sector and is quite common. The beneficiaries of this water reallocation system are not only the rural elite, for example the large and politically influential landlords, but also the small and medium capitalist farmers. If not properly addressed, these complications of decreasing water resources could result in serious political and economic hostility among the provinces. If it wants to harness its potential to increase storage capacity, Pakistan must improve its water-use efficiency and manage its groundwater and surface water resources in a sustainable way. Strengthening the institutions and removing mistrust among the provinces are the key elements for maintaining a sustainable irrigated agriculture in the Indus Basin.

African urban areas and cities are primarily seen as vulnerable to climate change. Apparent attempts to get required policies have led to the widespread proliferation of overlapping and duplications of policies. Using a policy coherence framework, this study aims to synthesise the coherency of climate adaptation and urban policies in Ghana. The study used content analysis of existing policy documents to understand if specific variables are explicit, implicit or not mentioned in four urban and climate change policies in Ghana. It was found that there is a minimal degree of coherence only in the adaptation measures, but there is a general lack of coherence in the motivation and implementation. This can be attributed to radically different current institutional arrangements for urban planning and climate change, inconsistent use of data and terminologies, and lack of embracement of innovations in urban planning in African cities. The findings suggest that attention must be given to integrated collaborative adaptation planning to address these impediments in urban planning context of African cities.
