The Three-Points Sponge Policy approach; toward an enhanced multi-level resilience strategy

Urban water management is confronted with more frequent, more extreme weather events. This paper introduces the Three-Points Approach (3PA) into Sponge City concept, to create a novel framework aimed at guiding water management interventions across local, urban, regional, and river basin scales. The 3PA integrates three domains—Day-to-day, Design, and Extreme —offering a nuanced strategy for flood and drought risk mitigation, also for extreme events. Notably, the 3PA emphasizes the fusion of blue-green infrastructure (BGI) with conventional gray approaches to enhance both multifunctionality and resilience in extreme weather conditions. The study identifies critical issues of implementing this Three-Points Sponge Policy (3PSP) approach, including spatial and temporal scales, transitioning from gray to blue-green infrastructure, asset management, data handling, and effective communication. Interventions spanning various spatial scales and addressing flood protection, drought resilience, and water quality are explored in a first and indicative application in Zhengzhou. The case study distills key design principles, highlighting the imperative of never shifting problems, embracing ecosystem-based adaptation, seeking synergy between interventions, and incorporating adaptability into designs. The 3PSP approach emerges as a holistic framework that considers both risks and benefits, contributing valuable insights to the discourse on integrating urban and river basin water management, improving our ways of dealing with extreme weather events while maximizing the day-to-day benefits of our interventions.

Drought susceptibility mapping in Iraq using GRACE/GRACE-FO, GLDAS, and machine learning algorithms

Drought susceptibility mapping is crucial for mitigating water scarcity and its cascading effects. This study utilizes machine learning (ML) and Gravity Recovery and Climate Experiment (GRACE) data to identify drought-prone areas in Iraq. Terrestrial water storage anomaly (TWSA) data derived from GRACE observations was utilized, in conjunction with various meteorological and topographical factors (temperature, precipitation, wind speed, potential evapotranspiration, aridity index, normalized difference vegetation index, groundwater storage, root zone moisture, elevation, and slope) sourced from diverse global datasets, primarily those comprising the Global Land Data Assimilation System (GLDAS). These combined datasets served as input for five machine learning models to identify the drought prone area of Iraq: linear discriminant analysis, classification and regression trees, support vector machine, random forest, and k-nearest neighbor. All models exhibited exceptional performance (>0.9 accuracy, >0.8 kappa values, >0.9 areas under the receiver operating characteristic curve) highlighting the effectiveness of the combined TWSA and multi-factor approach. The analysis identified five drought susceptibility zones across Iraq, ranging from very low to very high. An area of approximately 160,650 km2, primarily concentrated in the northeastern and Mesopotamian plains of central and southern Iraq, was identified as exhibiting high to very high drought susceptibility, highlighting the necessity for targeted mitigation strategies. This study pioneers the use of GRACE-derived TWSA and GLDAS data for drought susceptibility mapping in Iraq, paving the way for data-driven water management interventions.

Agricultural drought risk and local adaptation measures in the Upper Mun River Basin, Thailand

Northeast Thailand is one of the country's important agricultural regions. Yet, it is frequently grappled by droughts affecting crop production as most of the cultivation depends on rain-fed irrigation. This study employs a comprehensive framework for assessing the drought risk in the Mun River basin, including hazard, exposure, and vulnerability factors. Hazard is estimated using a multivariate approach considering drought duration and severity, while exposure and vulnerability are evaluated using eighteen proxy factors encompassing physical and socioeconomic aspects. Local adaptation measures adopted by farmers to cope with droughts are an integral part of the risk assessment framework. Factors are normalized to five equally spaced categories and are aggregated using weights obtained from AHP through a survey among 50 local experts. Further, an extensive survey was conducted among 122 farmers in two hotspots with high hazards but contrasting vulnerability to investigate adaptation practices. Experts in the region perceive a higher importance of adaptive capacity than drought susceptibility while defining vulnerability. The results show that people living in areas with high hazard levels and physical vulnerability also tend to have a higher adaptive capacity to manage water scarcity. Overall, 22% of the area is under high to very high drought risk. Specifically, 14% of the area in Nakhon Ratchasima, 15% in Buriram, 8% in Surin, and 19% in Si Sa Ket provinces have very high risk. Among two hotspots, Dan Khun Thot district farmers have diversified crops and practiced various adaptive measures to build their resilience against drought and have low vulnerability and risk. In contrast, adaptation measures are implemented to a far lesser extent in the Phlapphla Chai district and have high vulnerability and risk. The education level of farmers is found to be directly linked with the implementation of local adaptation measures. The disparity in the adaptive measures adopted in two districts highlights the significance of agricultural water management interventions. Access to climate information regarding droughts, building farm ponds, and crop management practices are the preferred adaptation measures taken by the farmers. The study recommends districts in each province identified as having high risk are prioritized and supported by the local government to improve farm-level water management practices and drought resilience. It is imperative as looming climate change will further exacerbate future droughts.

(Re)visiting and (Re)valuing the Vanishing Water Heritage in VOC Asia: Dutch Malacca and Ceylon

Dutch engineers are well-known for their skillful water management, best exemplified in the meticulously designed canals, irrigation and drainage systems, reservoirs, wells and moats that characterize both the Netherlands and places abroad where they have been active. Many of these structures that exist outside the Netherlands and were created by the Dutch East India Company (Verenigde Oostindische Compagnie, VOC, between 1602-1795) in Asia remain understudied. This article identifies and revisits these forgotten and often vanishing water structures through both archival and field research in Dutch Malacca and Ceylon. It explores the ways in which water management interventions during the VOC period recognized and made use of built-upon local wisdom, systematically adapting environmental knowledge into Dutch technology and governance to improve living in the tropics for both the Dutch and the local hybrid communities. Dutch water structures from the VOC period in Malacca in contemporary Malaysia and present-day Sri Lanka are examples of VOC approaches to tackling challenges in tropical environments. These historic sites – including heritage sites, some of which are recognized as UNESCO World Heritage properties – can be informative about how to adapt to current climate situations, both in terms of spatial structures and in terms of intangible practices, including cultural wisdom derived from strategies developed by the Dutch and from interactions between Dutch and local hybrid communities.

Artificial intelligence for decentralized water systems: A smart planning agent based on reinforcement learning for off-grid camp water infrastructures

Abstract The planning and management of decentralized technologies in water systems is one of the promising, yet overlooked, domains where artificial intelligence (AI) can be successfully applied. In this study, we develop and deploy a reinforcement learning (RL)-based ‘smart planning agent’ capable of designing alternative decentralized water systems under demanding operational contexts. The agent's aim is to identify optimal water infrastructure configurations (i.e., proposed decisions on water management options and interventions) for different conditions with regard to climate, occupancy and water technology availability in a demanding, off-grid setting, i.e., a water system with high requirements of independence from centralized infrastructure. The agent is coupled with a source-to-tap water cycle simulation model capable of assessing and stress-testing the proposed configurations under different conditions. The approach is demonstrated in the case of a military camp deployed abroad for peacekeeping operations. The agent is tasked with selecting optimal interventions from an array of real-world camp water management technologies and evaluating their efficiency under highly variable, operational conditions explored through simulation. The results show that RL can be a useful addition to the arsenal of decision support systems (DSS) for distributed water system planning and management, especially under challenging, highly variable conditions.

Containment of a Verona Integron-Encoded Metallo-Beta-Lactamase-Producing Pseudomonas aeruginosa Outbreak Associated With an Acute Care Hospital Sink-Tennessee, 2018-2020.

Contaminated healthcare facility wastewater plumbing is recognized as a source of carbapenemase-producing organism transmission. In August 2019, the Tennessee Department of Health (TDH) identified a patient colonized with Verona integron-encoded metallo-beta-lactamase-producing carbapenem-resistant Pseudomonas aeruginosa (VIM-CRPA). A record review revealed that 33% (4 of 12) of all reported patients in Tennessee with VIM had history of prior admission to acute care hospital (ACH) A intensive care unit (ICU) Room X, prompting further investigation. A case was defined as polymerase chain reaction detection of blaVIM in a patient with prior admission to ACH A from November 2017 to November 2020. The TDH performed point prevalence surveys, discharge screening, onsite observations, and environmental testing at ACH A. The VIM-CRPA isolates underwent whole-genome sequencing (WGS). In a screening of 44% (n = 11) of 25 patients admitted to Room X between January and June 2020, we identified 36% (n = 4) colonized with VIM-CRPA, resulting in 8 cases associated with Room X from March 2018 to June 2020. No additional cases were identified in 2 point-prevalence surveys of the ACH A ICU. Samples from the bathroom and handwashing sink drains in Room X grew VIM-CRPA; all available case and environmental isolates were found to be ST253 harboring blaVIM-1 and to be closely related by WGS. Transmission ended after implementation of intensive water management and infection control interventions. A single ICU room's contaminated drains were associated with 8 VIM-CRPA cases over a 2-year period. This outbreak highlights the need to include wastewater plumbing in hospital water management plans to mitigate the risk of transmission of antibiotic-resistant organisms to patients.

Sustainable Farming in Practice: Building Resilient and Profitable Smallholder Agricultural Systems in Sub-Saharan Africa

Sub-Saharan Africa is at crossroads. With a rapidly growing population of 1.2 billion and changing climates, the continent faces major development challenges, including food insecurity, climate change, resource degradation, poverty, gender inequality, and social exclusion. While there are multiple competing narratives promoted in the high-input, industrialised world to address climate change and the resilience of agricultural systems (e.g., regenerative agriculture, agroecology), there is an ongoing debate and genuine questions about the appropriateness of these approaches to small-scale farmers in SSA. African agricultural systems are unique, characterised by low productivity, nutrient mining, land degradation, hoe culture, and fragmented and diversified small farms. Though environmental pollution and over-dependence on fossil fuel-powered mechanisation are rarely topping the priority list, climate change is becoming a major concern. The top-down narratives from environment-concerned communities lack the tools to address the most pressing and immediate challenge of local communities in Sub-Saharan Africa, namely (i) intensification by increased crop productivity per unit of inputs, (ii) increased access to rural energy forcing farmers to use available biomass for cooking instead of soil regeneration; (iii) the intent of no use or reduced mineral fertilisers, in a system marred by nutrient mining over centuries; and (iv) failure to address recurrent drought through integrated soil water management interventions. To address these specific challenges, we present context-specific, outcome-oriented farming solutions as a viable and appropriate strategy called ‘sustainable farming’. We argue that the nature-based narratives will remain to be important but will be better adopted if they respond to local demands and context-specific challenges of small-scale farmers. By means of three successful land restoration programmes in East Africa, we present eight outcomes that should be addressed to ensure sustainable farming of small holdings and reduce the risk of climate change. For these innovations to be adopted at scale, we proposed to put in place incentive mechanisms and functional last-mile delivery systems.

Climate and Human Impacts on Hydrological Processes and Flood Risk in Southern Louisiana

AbstractSatellite observations of coastal Louisiana indicate an overall land loss over recent decades, which could be attributed to climate and human‐induced factors, including sea level rise (SLR). Climate‐induced hydrological change (CHC) has impacted the way flood control structures are used, altering the spatiotemporal water distribution. Based on “what‐if” scenarios, we determine relative impacts of SLR and CHC on increased flood risk over southern Louisiana and examine the role of water management, via flood control structures, in mitigating flood risk over the region. Our findings show that CHC has increased flood risk over the past 28 years. The number of affected people increases as extreme hydrological events become more exceptional. Water management reduces flood risk to urban areas and croplands, especially during exceptional hydrological events. For example, currently (i.e., 2016–2020 period), CHC‐induced flooding puts an additional 73 km2 of cropland under flood risk at least half of the time (median flood event) and 65 km2 once a year (annual flood event), when compared to a past period (1993–1997). A 10‐ to 20‐fold increase relative to SLR‐induced flooding. CHC also increases population vulnerability in southern Louisiana to flooding; additional 9,900 residents currently live under flood risk at least half of the time, and that number increases to 27,400 for annual flood events. Residents vulnerable to SLR‐induced flooding is lower (6,000 and 3,300 residents, respectively). Conclusions are that CHC is a major factor that should be accounted for flood resilience and that water management interventions can mitigate risks to human life and activities.

Place for sociohydrology in sustainable and climate-resilient agriculture: Review and ways forward

Abstract Given the increasing demand for high-quality food and protein, global food security remains a challenge, particularly in the face of global change. However, since agriculture, food and water security are inextricably linked, they need to be examined via an interdisciplinary lens. Sociohydrology was introduced from a post-positivist perspective to explore and describe the bidirectional feedbacks and dynamics between human and water systems. This review situates sociohydrology in the agricultural domain, highlighting its contributions in explaining the unintended consequences of water management interventions, addressing climate change impacts due to/on agriculture and incorporating human behaviour into the description of agricultural water systems. Sociohydrology has combined social and psychological insights with novel data sources and diverse multi-method approaches to model human behaviour. However, as agriculture and agriculturalists face global change, sociohydrology can better use concepts from resilience thinking more explicitly to identify gaps in terms of desirable properties in resilient agricultural water systems, potentially informing more holistic climate adaptation policy.

Adapting irrigated agriculture in the Middle Rio Grande to a warm-dry future

Study regionMiddle Section of the Rio Grande Basin (MRG), U.S. Study focusLong-term tradeoffs of technologically possible land and water management interventions were analyzed to adapt irrigated agriculture to growing water scarcity in a desert environment under a projected warm-dry future. Nineteen different intervention scenarios were investigated to evaluate potential watershed-scale agricultural water savings and associated water budget impacts in the MRG. The interventions are based on (i) management innovations of growers in implementing deficit irrigation and changing cropping patterns using existing crops, (ii) changing cropping patterns by introducing new alternative drought- and salt-tolerant crops, and (iii) limitations of the soil and water assessment tool (SWAT) model to perform scenario simulations. New hydrological insights for the region(1) status quo irrigation management cannot sustain the current crop mix in the face of dwindling river water and likely fresh groundwater depletion within the 21st century; (2) existing cropping and irrigation interventions create limited water savings; and (3) deficit irrigation of alfalfa or removing it from the crop mix allows moderate water savings to sustain high-value perennial pecan crops but the region will remain vulnerable to intensive, prolonged droughts. Strategies for future agricultural water sustainability in the study area could include transitioning to relatively drought- and salt-tolerant crops, desalinating brackish groundwater for irrigation, and developing water markets to increase flexibility in water use.

Temporal and Spatial Water Quality Assessment of the Geumho River, Korea, Using Multivariate Statistics and Water Quality Indices

The Geumho River in South Korea passes through a metropolitan area with a high population density and multiple industrial complexes; therefore, the water quality of this river is of significance for human health and economic activities. This study assesses the water quality of the Geumho River to inform river water quality management and improve pollution control using multivariate statistics and the Korean Water Quality Index (KWQI). Principal component and factor analyses identified factors related to organic pollutants and metabolism (principal factor 1) and phosphorus and fecal coliform content (principal factor 2). Based on the results of the cluster analysis, it was classified into four groups in time and three groups in space. Six temporal variables and seven spatial variables were extracted from discriminant analysis results; the most important water quality variables were high during the spring and summer seasons and in the midstream and downstream regions. Temporally, the KWQI was the highest in winter and the lowest in spring; spatially, the KWQI was the highest in the upstream and the lowest in the midstream sections. These results indicate that to improve effectiveness, water management interventions in the Geumho River should focus on the urban midstream section and spring season.

Evaluation of water footprint in sugar industries and bioethanol distilleries in two different water basins toward water sustainability.

Sugarcane farming and bioethanol production are water-intensive activities that result in high water competition. The competition, in turn, can exacerbate water scarcity. Therefore, this study aims to evaluate the water footprint (WF) of the sugar and bioethanol production at the Finchaa and Metehara sugarcane farms, which are located in different river basins in Ethiopia. The climatic data (minimal and maximum temperature, relative humidity, wind speed, and sunshine duration), meteorological data (rainfall), CROPWAT 8.0 model, nitrogen fertilizer application rates, sugarcane yield, and sugar and bioethanol production over 12 years (2008–2019) were used. Penman–Monteith method-based sugarcane water requirements of Finchaa and Metehara were found to be 2021.1 and 3605.4 mm/growing period, respectively. The sugarcane WF of Finchaa was 188.01 m3/t, which was composed of green (67.45 m3/t), blue (113.42 m3/t), and grey (7.14 m3/t) components, whereas the WF of Metehara was 239.11 m3/t consisting of green (29.42 m3/t), blue (204.13 m3/t), and grey (5.56 m3/t). The low sugarcane WF recorded was attributed to the high yield of sugarcane that was harvested in the study areas. Hence, the irrigation (blue WF) requirement is the major concern of water management in the basins. Similarly, the WF of bioethanol at the Finchaa distillery (2067.62 L/L) was much higher than that of the Metehara distillery (1441.54 L/L). However, both WFs were within the global range. Significant differences were observed between the two water basins. The sugarcane estate farm and bioethanol production processes require water management intervention to reduce the impact of WF in the basins.

Operationalising nature-based solutions for the design of water management interventions

Water resources are affected by several pressures, including pollution, abstractions, droughts, and floods, as well as physical modifications such as land use changes, drainage, soil erosion, channelisation and barriers amongst others. Protecting water resources requires managing these pressures and designing cost-effective interventions to reduce their impact on the water environment. In recent years, the emergence of an integrated approach driven by the implementation of the Water Framework Directive (WFD) in Europe, and a shift towards sustainable catchment management, have brought to the forefront the need for understanding the catchment as a system and managing it by aligning human-nature interdependencies with the goal of improving it as a whole. In this context, nature-based solutions have the potential to outperform the end of pipe solutions used to protect the environment while delivering multiple benefits. In this study, we review the potential of such an approach and evaluate the role of nature-based solutions as interventions for catchment management in the context of the WFD. Through a case study, we examine the effectiveness of a privately funded wetland in improving effluent quality of a water recycling centre and assess the economic value of generated ecosystem services. Findings demonstrate that the designed nature-based solution contributes significantly to achieving water quality targets, while being able to offer key economic benefits through carbon sequestration and the provision of habitat for species. The study confirms that nature-based solutions and their operation in tandem with traditional grey infrastructure, have the potential to improve water management practices and unlock private sector investment for the protection of the environment.

On viability: Climate change and the science of possible futures

Growing attention to the impacts of climate change around the world has been accompanied by the profusion of discourses about the lives, livelihoods, and geographies that are “viable” and those that are not in the time of climate change. These discourses of viability often invoke concrete physical limits and tipping points suggesting a transcendent natural order. Conversely, I demonstrate how viability is co-produced through political economic structures that exercise power at multiple scales in shaping the environment and understandings of how it is changing. I describe three dialectics of this co-production: epistemic/material (between ideas about viability and their biophysical and political economic conditions), epistemic/normative (between how the world is understood to be and ideas about how we should live in it), and inter-scalar (between geographic scales, where action at one scale shapes both ecologies and understandings of possible action at another). Each of these dialectics shapes the knowledge regimes that govern the ambiguous social and biophysical process of disappearance and foreclosure of livelihood possibilities in the time of climate change. I examine these discourses of viability through narratives of unviable agrarian livelihoods in coastal Bangladesh, as a lens through which to examine the dialectics of viability more broadly. I situate these discourses concretely in relation to an analysis of interdisciplinary social and natural scientific research on ecological and agrarian viability in coastal Bangladesh now and in the future. Across a broad interdisciplinary spectrum, I find that scientific attention to political economy shapes the politics of possibility. Finally, I demonstrate how discourses of viability limit alternative possible economic and ecological futures. I do this through a concrete examination of the co-production of viable agrarian futures within communities in coastal Bangladesh. These alternative visions indicate that the viability of agriculture is shaped by historical and ongoing decisions in the present about cultivation, water management, and development intervention.

Impact of raised beds on surface runoff and soil loss in Alfisols and Vertisols

Hydrological monitoring is crucial to designing agricultural water management (AWM) interventions. This study characterizes the soil hydraulic properties of Alfisols and Vertisols and develops rainfall-runoff-soil loss relationships through long-term hydrological monitoring. Two types of landform management techniques, i.e., raised bed and flat bed, were followed in three paired watersheds of 2–5 ha, characterized by deep Vertisols, medium deep Vertisols and Alfisols. Surface runoff and soil loss were monitored at the outlet of the respective watersheds for 8–12 years. In addition, 29 infiltration tests were conducted using a tension disc infiltrometer by applying a suction of −150 mm, −100 mm, −50 mm, and −20 mm. Soil macro porosity and hydraulic conductivity in the raised bed landform were found to be almost double those in the flat beds at −50 mm suction head in both the soil types. Saturated hydraulic conductivity was found higher in Alfisols compared to Vertisols; however, less runoff was generated in Vertisols compared to Alfisols. This phenomenon is largely explained by the high water storage capacity of Vertisols. Runoff generated from both the soils was less than 2% of total rainfall (<500 mm) received in dry years. In normal years (600–900 mm), runoff coefficient for Vertisols ranged from 7–11% of total rainfall compared to 16–17% in the case of Alfisols. However, runoff generated from fallow land was 17% in deep Vertisols due to higher soil moisture content and limited available storage compared to the cropped land. The raised bed method reduced surface runoff by 15–20 mm in Alfisols compared to 35–40 mm in Vertisols. Runoff from the raised beds was significantly lower during light and moderate intensity rainfall compared to the flat bed method; however, this difference was not significant during events of high and very high intensity rainfall. In addition, raised beds reduced soil loss by 30–60% compared to flat beds. The results of this study are useful in designing evidence-based AWM strategies under rainfed conditions.

Impact of agricultural water management interventions on upstream–downstream trade‐offs in the upper Cauvery catchment, southern India: a modelling study*

AbstractThe Cauvery basin in southern India is experiencing transboundary issues due to increasing water demand. This study analysed water balance components and the impact of agricultural water management (AWM) interventions in the upper Cauvery catchment of the Cauvery basin. Results showed that the study catchment receives an average of 1280 mm of annual rainfall. Of this, 29% (370 mm) flows downstream, 54% (700 mm) contributes to evapotranspiration (ET) and 17% (215 mm) contributes to groundwater recharge and surface storage. Rainfall varies from 700 to 5400 mm and the Western Ghats (mountain pass) are the main source of freshwater generation. The estimated ET in different catchments ranged from 500 to 900 mm per annum. An increase in the allocation of fresh water supplied by all three reservoirs (Hemavathi, Harangi and KRS) was observed in the canal command areas, from 1450 million cubic metres (MCM) yr‾¹ in 1971–1980 to 3800 MCM yr‾¹ in 2001–2010. AWM interventions harvested 140–160 MCM (13–20 mm) of surface runoff upstream of the upper Cauvery and reduced inflow into the Krishnaraja Sagar reservoir by 2–6%. The study findings are useful for designing and planning suitable water management interventions at basin scale.

A novel approach to baseline water quality assessment at local and catchment scale: a case study from Berambadi, India.

Optimal design and maintenance are necessary for the sustainability of wastewater treatment systems. In this study, we present the outcome of a novel approach to baseline assessment conducted prior to the design and deployment of a decentralized wastewater treatment system at a school in rural India. The baseline water quality monitoring protocol was deployed to assess (a) the quality and quantity of wastewater (greywater and blackwater) flows from the school and (b) the status of surface water and groundwater quality in the catchment. Hourly greywater flows and water quality trends were monitored across four seasons at the school. Average freshwater consumption at the school was 518 ± 322 L/day for hand washing and 287 ± 97 L/day for cooking meals. Greywater generation showed high hourly variations in COD levels. Greywater generated from hand wash and kitchen sources contributed to 110g/day and 96g/day of BOD5 respectively and 214g/day and 141g/day of COD respectively. Based on additional data from a self-reporting sanitation survey, the organic contaminant load generated from the toilet was estimated to be 1.5 ± 0.1kg COD/day. At the catchment scale, both groundwater and surface water quality were monitored seasonally to assess the impact of raw sewage and stormwater inputs. Compared with borewells, high nitrate-N levels (> 10mg/L) were observed in the village hand pump samples throughout the year. Maximum nitrate-N (16mg/L) and fecal coliforms (3.9 log MPN/100mL) levels were observed in surface waters during monsoons, indicating the impact of sewage and surface runoff on water quality. The proposed approach is useful to estimate data on freshwater use and wastewater generation at the school and hence to make the case for, and design of, a sustainable water management intervention.

Land property rights and household take-up of development programs: Evidence from land certification program in Ethiopia

• The study examines the impact of land property rights on take-up of agricultural development interventions in Ethiopia. • We find that land certification has a positive impact on the take-up of agricultural extension package program. • Land certification status significantly predicts farm household adoption of chemical fertilizer. • Secure land rights play a key role in household participation in community level land and water management programs. • The study promotes land rights as mechanism to promote agricultural development and sustainable land and water management. Access to secure land plays a key role in the socio-economic development of agricultural households. Since 1998, large-scale land certification programs aimed at strengthening the land property rights of agricultural households in Ethiopia have been implemented across regions to varying degrees. Using a three-period, large-scale nationally representative panel dataset from Ethiopia, this paper investigates the importance of access to secure land property right in the form of land certification for household take-up of agricultural development interventions that aim to improve household agricultural productivity and sustainable land use at a community level. We studied the take-up of agricultural extension packages and participation in community level sustainable land and water management programs as outcome variables. To account for potential endogeneity in the allocation of certificates and other confounding factors, we applied different panel data methods including instrumental variable approach. We find that access to secure property rights have a positive and significant effect on household take-up agricultural development interventions: agricultural extension packages and sustainable land and water management interventions. Additionally, we find that land certificates significantly predict household adoption of chemical fertilizers.

Sustainable Urban Water Management in China: A Case Study from Guangzhou and Kunming

In China, the notion of a water sensitive city has gained popularity in urban water management as a result of the detrimental effects of flooding and pollution caused by developmental activities. Urban systems and their interrelationships are critical for long-term urban water management and water sensitivity. This article is a case study considering how a strength, weakness, opportunities, and threat (SWOT) analysis-based approach to urban water management interventions in Guangzhou and Kunming cities (China) enables decision makers to identify solutions for cities to become more water-sensitive and resilient. The similar difficulties and rewards with respect to the contexts of both cities were synthesized using SWOT analysis. The contextual SWOT analysis, in conjunction with the comprehensive inclusion of Sustainable Development Goals (SDGs) in intervention planning in these cities, revealed that a water-sensitive-cities approach requires the establishment of a comprehensively multi-objective rainwater management system; this approach would have the goals of reducing rainwater draining sources, controlling processes and adaptive measures, and governing the system to make it more resilient. The water strategy should be holistic and adaptive, capable of providing a broad range of ecological services and other social benefits consistent with the fulfilment of the Sustainable Development Goals, and adaptable to other Chinese cities seeking to achieve water sensitivity.

Socioeconomic Impact Assessment of Water Resources Conservation and Management to Protect Groundwater in Punjab, Pakistan

Water is the most important resource; it is utilized largely in agricultural production and is fundamental to ensuring global food security. This study aims to assess sustainable water management interventions and their impact on the farm economy. To increase water productivity, the most important adaptations that have been proposed are high-efficiency irrigation systems, drought-resistant varieties, the substitution of water-intensive crops with less water-demanding crops, the mulching of soil, zero tillage, and all on-farm operations that can save water, especially ground water. The recent analysis utilized farm survey data from 469 representative farmers along with secondary statistics. The data were collected via a multi-stage sampling technique to ensure the availability of representative farm populations based on a comprehensive site selection criterion. The TOA-MD model estimates the adoption rate of a proposed adaptation based on net farm returns. The impact of high-efficiency irrigation systems and the substitution of high delta crops for low delta crops had a positive impact on net farm returns and per capita income, and a negative impact on farm poverty in the study area. It is recommended that policymakers consult farmer representatives about agricultural and water-related issues so that all the policies can be implemented properly.
