Guidelines for assistive technology service provision – A scoping review

Purpose: Despite the high unmet need for effective AT provision, multiple service delivery models across different countries, and a shortage of personnel trained in this field, no widely useable and accepted Assistive Technology (AT) service provision guidelines currently exist. This review aims to provide an overview of the literature regarding AT service provision guidelines to inform the development of globally useable AT provision guidance, aligned with contemporary global initiatives to improve access to AT. Materials and Methods: The rapid scoping review method used a two-tiered approach to identifying relevant publications: (1) systematic search of academic databases (Medline, CINAHL, SCOPUS, and Google Scholar); (2) consultation with international AT organisations and experts. The search was conducted in March 2023 with no date limitations. Analysis was guided by the TIDE-funded HEART research on quality AT provision and service delivery processes in Europe, as well as the WHO-GATE 5 P framework for strengthening access to AT. Results: 35 publications were identified from various countries, and directed at differing assistive products, personnel, and provision contexts. No established guidelines for AT service provision currently exist. However, despite the variety in contexts, the range of assistive products and the range of stakeholders to whom guidelines are directed, several key service delivery steps were identified that may form part of such guidelines. Conclusions: This review offers a strong starting point for developing guidance for AT provision to meet global needs. Careful consideration of vocabulary, process, and application to the diversity of assistive products is recommended in systematizing globally applicable guidance.

Deforestation impacts soil biodiversity and ecosystem services worldwide

Deforestation poses a global threat to biodiversity and its capacity to deliver ecosystem services. Yet, the impacts of deforestation on soil biodiversity and its associated ecosystem services remain virtually unknown. We generated a global dataset including 696 paired-site observations to investigate how native forest conversion to other land uses affects soil properties, biodiversity, and functions associated with the delivery of multiple ecosystem services. The conversion of native forests to plantations, grasslands, and croplands resulted in higher bacterial diversity and more homogeneous fungal communities dominated by pathogens and with a lower abundance of symbionts. Such conversions also resulted in significant reductions in carbon storage, nutrient cycling, and soil functional rates related to organic matter decomposition. Responses of the microbial community to deforestation, including bacterial and fungal diversity and fungal guilds, were predominantly regulated by changes in soil pH and total phosphorus. Moreover, we found that soil fungal diversity and functioning in warmer and wetter native forests is especially vulnerable to deforestation. Our work highlights that the loss of native forests to managed ecosystems poses a major global threat to the biodiversity and functioning of soils and their capacity to deliver ecosystem services.

Multiple Myeloma in Zimbabwe. Knowledge Levels, Age and Sex as Risky Factors. Insights from Zimbabwe Multiple Myeloma Consortium

Multiple myeloma is a serious cancer of the blood affecting millions of people across the world and is the second most prevalent hematological disease accounting for 10% of hematological disease cases while representing 1% of all serious diseases in the world. Multiple myeloma is also a major threat in Sub-Saharan Africa as revealed by the statistics provided by the Ríos-Tamayo, Rodríguez, Chang-Chan, & Pérez (2018) . On average, according to Globocan (2020), 3.2 per 100 000 have MM in Southern Africa, while there are 0.98 and 0.83 per 100 000 people with MM in Eastern Africa and Western Africa respectively. This indicates that Southern Africa is disproportionately affected by multiple myeloma. This is particularly the cases with Zimbabwe in which the number of people with MM is estimated to be 2.69 per 100 000 people along with a 5-year prevalence of 400 new cases every year (Globocan, 2020). It is from this background that, the Zimbabwe multiple myeloma consortium funded by the Bristol Myers Squib Foundation implemented the multiple myeloma project in Zimbabwe since April 2022. Objectives of the project include the need to improve patients’ quality of life, to improve multiple myeloma service delivery systems and effects of multiple myeloma, where patients efficiently and effectively get diagnostic and palliative care services as well as increasing multiple myeloma awareness and knowledge levels among the general population and health workers of Zimbabwe. This article provides statistics to give insights of multiple myeloma in Zimbabwe in terms of case findings conducted to date as well as number of MM patients identified. Mixed method was employed where data was collected and captured using Qualtrics system integrating both qualitative and quantitative. Thematic analysis was incorporated to analyse qualitative data using 5 different steps namely: familiarization, generating initial codes, search for themes, reviewing of themes and write up. Participants for this research were drawn from a caseload of 181 patients. These patients received their services from Parirenyatwa Group of Hospitals, Gweru Provincial Hospital and Mpilo Hospital in Bulawayo. Findings of this research indicated that, there is deaths of multiple myeloma information among health care workers, professionals such as physicians and orthopaedics as well as general population. Late diagnosis has seen to be a cause for concern among mm patients. Males are the most vulnerable population to be affected by the disease and again ageing is a contributing factor. Recommendations made include but not limited to; targeted sensitisation reaching out to oncologists, physicians, orthopaedics health care workers, workplaces and tertiary institutions. This will translate to early diagnoses thereby improving quality of life. More funding is needed to support treatment of mm patients and as enablers to conduct home visits in relation to palliation activities by service providers. Social media engagement to be an ongoing endeavour packaged with mm risk factors, signs and symptoms related information.

Feature selection based machine learning models for 5G network slicing approximation

The development of 5G networks is expected to introduce novel concepts and challenges in domains such as technology, security, and customer demands due to advancements in mobile internet and communication services. The three main services that the 5G network provides are enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). Network slicing is the practice of dividing a single physical network into many virtual networks in order to facilitate the delivery of multiple services across that network. These slices improve the network’s reliability and make it possible to provide more customized services. This article provides an overview of 5G network slicing, discussing its layers and overall architecture. Additionally, the paper proposes a machine learning network slicing model based on feature selection, comprising three main components. Firstly, data collection involves gathering two different datasets from various sources. Secondly, feature selection algorithms are applied to choose the most relevant set of features, as the collected datasets may contain numerous unnecessary attributes and values. Lastly, various classification models are utilized on the selected features to predict the optimal network slice, thereby improving the efficiency of the 5G network. The analytical results and simulation models demonstrate that the proposed machine learning models with feature selection perform exceptionally well and accurately predict 5G network slices.

Service-Aware Resource Orchestration in Ultra-Dense LEO Satellite-Terrestrial Integrated 6G: A Service Function Chain Approach

With the rapid expansion of the scale of deployed low earth orbit (LEO) satellites, the ultra-dense LEO satellite-terrestrial integrated network (LTIN) is envisioned as a promising architecture in the sixth-generation (6G) system to implement seamless connectivity and high-speed data rate service. Especially for ultra-remote real-time services with long transmission distance and high delay requirements, the integrated network can guarantee its end-to-end service continuity. However, many challenges have been posed to the efficient resource orchestration for the service delivery, owing to the large scale, heterogeneity and high mobility of the integrated network. For each service, its data needs to go through a series of on-board processing, before being downloaded to the terrestrial network for further applications. To this end, service function chain (SFC), an ordered concatenation of network functions (NFs), is introduced to support service provision. By allocating the constituent NFs over the LTIN, we propose an efficient multiple service delivery scheme to minimize the overall delivery completion latency, while taking into account resource sharing and competition among multiple SFCs. First, we formulate the multiple SFC embedding problem as a noncooperative game that is further proved as the weighted potential game with at least one Nash equilibrium (NE). With the help of the proposed global coordination mechanism, we design two algorithms to obtain the NE. One is the best response (BR) algorithm with faster convergence, while the other is adaptive play (AP) algorithm with more capacity for best solutions. Then, the stochastic learning (SL) algorithm is proposed to adapt to network dynamics and reduce global information exchange. Finally, extensive simulations validate the convergence and effectiveness of the proposed algorithms.

Land use change and soil organic carbon dynamics: A case study with institutional establishment

The advancement of human civilizations exacerbated land use changes for settlements, agriculture, and development projects, etc. and affected the delivery of multiple ecosystem services. In the present study, land use and land cover changes (native forests) resulting from physical structures (educational institutes) have been studied for their role in soil organic carbon dynamics. In the study area (1) soil organic carbon (SOC) content for the transitional land uses was in the order of natural forest (17.27 g kg−1) > recreational forest (12.65 g kg−1) > ecoforest (11.14 g kg−1) > degraded forest (9.92 g kg−1), and had significant reciprocal relation with the increasing vertical soil profile. (2) Pearson's correlation revealed a significant positive relation between SOC and soil moisture (r = 0.599), and vertical soil profiles of each land use had discrete cluster arrangement by SOC composition. The establishment of physical structures severely reduced SOC content due to the degradation of native vegetation; however, with intentional management of the ecoforest and recreational forest, a part of the green campus initiative has partially restored the soil health. The current practice of delineating of forest management practices provided partial solutions for the institutional forest and soil health management.

Tackling “half” of the non-communicable disease burden in Bangladesh: a diagonal service delivery model with a life-course approach

In the context of increasing morbidity and mortality due to non-communicable diseases (NCDs) globally and particularly in low-resource countries, it has become important to explore newer health systems delivery models. In low-and middle-income countries (LMICs) women traditionally challenged with multiple barriers in accessing health services, are at even greater disadvantage compared to men. In Bangladesh, women constitute almost half of the country’s population and are disproportionately affected by NCDs like other LMICs. The country’s reproductive, maternal, newborn, child and adolescent health (RMNCAH) services are well established and designed to reach women in their households through community health workers (CHWs). This paper discusses how NCDs screening and control measures could be integrated into the existing RMNCAH pathway and proposes a conceptual model for such diagonal service delivery integration. The paper also describes multiple RMNCAH service delivery touchpoints that could be utilized for screening and treating women for NCD risk factors, across their life-course.

Intensification differentially affects the delivery of multiple ecosystem services in subtropical and temperate grasslands

Intensification, the process of intensifying land management to enhance agricultural goods, results in “intensive” pastures that are planted with productive grasses and fertilized. These intensive pastures provide essential ecosystem services, including forage production for livestock. Understanding the synergies and tradeoffs of pasture intensification on the delivery of services across climatic regions is crucial to shape policies and incentives for better management of natural resources. Here, we investigated how grassland intensification affects key components of provisioning (forage productivity and quality), supporting (plant diversity) and regulating services (CO2 and CH4 fluxes) by comparing these services between intensive versus extensive pastures in subtropical and temperate pastures in the USDA Long-term Agroecosystem Research (LTAR) Network sites in Florida and Oklahoma, USA over multiple years. Our results suggest that grassland intensification led to a decrease in measured supporting and regulating services, but increased forage productivity in temperate pastures and forage digestibility in subtropical pastures. Intensification decreased the net CO2 sink of subtropical pastures while it did not affect the sink capacity of temperate pastures; and it also increased environmental CH4 emissions from subtropical pastures and reduced CH4 uptake in temperate pastures. Intensification enhanced the global warming potential associated with C fluxes of pastures in both ecoregions. Our study demonstrates that comparisons of agroecosystems in contrasting ecoregions can reveal important drivers of ecosystem services and general or region-specific opportunities and solutions to maintaining agricultural production and reducing environmental footprints. Further LTAR network-scale comparisons of multiple ecosystem services across croplands and grazinglands intensively vs extensively managed are warranted to inform the sustainable intensification of agriculture within US and beyond. Our results highlight that achieving both food security and environmental stewardship will involve the conservation of less intensively managed pastures while adopting sustainable strategies in intensively managed pastures.

Un-yielding: Evidence for the agriculture transformation we need.

There has been a seismic shift in the center of gravity of scientific writing and thinking about agriculture over the past decades, from a prevailing focus on maximizing yields toward a goal of balancing trade-offs and ensuring the delivery of multiple ecosystem services. Maximizing crop yields often results in a system where most benefits accrue to very few (in the form of profits), alongside irreparable environmental harm to agricultural ecosystems, landscapes, and people. Here, we present evidence that an un-yielding, which we define as de-emphasizing the importance of yields alone, is necessary to achieve the goal of a more Food secure, Agrobiodiverse, Regenerative, Equitable and just (FARE) agriculture. Focusing on yields places the emphasis on one particular outcome of agriculture, which is only an intermediate means to the true endpoint of human well-being. Using yields as a placeholder for this outcome ignores the many other benefits of agriculture that people also care about, like health, livelihoods, and a sense of place. Shifting the emphasis to these multiple benefits rather than merely yields, and to their equitable delivery to all people, we find clear scientific evidence of win-wins for people and nature through four strategies that foster FARE agriculture: reduced disturbance, systems reintegration, diversity, and justice (in the form of securing rights to land and other resources). Through a broad review of the current state of agriculture, desired futures, and the possible pathways to reach them, we argue that while trade-offs between some ecosystem services in agriculture are unavoidable, the same need not be true of the end benefits we desire from them.

Creating a Design Framework to Diagnose and Enhance Grassland Health under Pastoral Livestock Production Systems

Grasslands and ecosystem services are under threat due to common practices adopted by modern livestock farming systems. Design theory has been an alternative to promote changes and develop more sustainable strategies that allow pastoral livestock production systems to evolve continually within grasslands by enhancing their health and enabling the continuous delivery of multiple ecosystem services. To create a design framework to design alternative and more sustainable pastoral livestock production systems, a better comprehension of grassland complexity and dynamism for a diagnostic assessment of its health is needed, from which the systems thinking theory could be an important approach. By using systems thinking theory, the key components of grasslands-soil, plant, ruminant-can be reviewed and better understood from a holistic perspective. The description of soil, plant and ruminant individually is already complex itself, so understanding these components, their interactions, their response to grazing management and herbivory and how they contribute to grassland health under different climatic and topographic conditions is paramount to designing more sustainable pastoral livestock production systems. Therefore, by taking a systems thinking approach, we aim to review the literature to better understand the role of soil, plant, and ruminant on grassland health to build a design framework to diagnose and enhance grassland health under pastoral livestock production systems.

Transhumant Sheep Grazing Enhances Ecosystem Multifunctionality in Productive Mountain Grasslands: A Case Study in the Cantabrian Mountains

Understanding the effects of traditional livestock grazing abandonment on the ability of mountain grasslands to sustain multiple ecosystem functions (ecosystem multifunctionality; EMF) is crucial for implementing policies that promote grasslands conservation and the delivery of multiple ecosystem services. In this study, we evaluated the effect of short- and long-term transhumant sheep abandonment on EMF through a grazing exclusion experiment in a grassland of the Cantabrian Mountains range (NW Spain), where transhumant sheep flocks graze in summer. We considered four key ecosystem functions, derived from vegetation and soil functional indicators measured in the field: (A) biodiversity function, evaluated from total plant species evenness, diversity and richness indicators; (B) forage production function, evaluated from cover and richness of perennial and annual herbaceous species indicators; (C) carbon sequestration function, evaluated from woody species cover and soil organic carbon indicators; and (D) soil fertility function, evaluated from NH4+-N, NO3–-N, P and K content in the soil. The EMF index was calculated by integrating the four standardized ecosystem functions through an averaging approach. Based on linear mixed modeling we found that grazing exclusion induced significant shifts in the considered individual ecosystem functions and also on EMF. Long-term livestock exclusion significantly hindered biodiversity and forage production functions, but enhanced the carbon sequestration function. Conversely, the soil fertility function was negatively affected by both short- and long-term grazing exclusion. Altogether, grazing exclusion significantly decreased overall EMF, especially in long-term livestock exclusion areas, while the decline in EMF in short-term exclusions with respect to grazed areas was marginally significant. The results of this study support the sustainability of traditional transhumance livestock grazing for promoting the conservation of grasslands and their ecosystem function in mountain regions.

Permanent grasslands in Europe: Land use change and intensification decrease their multifunctionality

Permanent grasslands cover 34% of the European Union’s agricultural area and are vital for a wide variety of ecosystem services essential for our society. Over recent decades, the permanent grassland area has declined and land use change continues to threaten its extent. Simultaneously, the management intensity of permanent grasslands increased. We performed a systematic literature review on the multifunctionality of permanent grasslands in Europe, examining the effects of land use and management on 19 grassland ecosystem service indicators. Based on the evidence in 696 out of 70,456 screened papers, published since 1980, we found that both land use change and intensification of management decreased multifunctionality. In particular, preventing conversion of permanent grasslands to croplands secured the delivery of multiple ecosystem services. A lower management intensity was associated with benefits for biodiversity, climate regulation and water purification, but impacted the provision of high-quality animal feed. Increasing the number of species in the sward enhanced multifunctionality of permanent grassland without significant trade-offs such as losses in production. Our review covered many aspects of land use, management and ecosystem services, but we also identified areas with no or only few studies. The most prominent gaps were related to comparisons between permanent and temporary grasslands, and effects of management practices on the provision of cultural values, and on erosion and flood control. We suggest that, despite apparent changes in human dietary preferences, the protection of permanent grasslands in Europe must be prioritised. At the same time, considering the need to reduce ruminant livestock’s contribution to climate change, the time seems ripe to increase support for low-intensity grassland management to optimise the provision of essential ecosystem services from Europe’s permanent grasslands.

Predicting field N2O emissions from crop residues based on their biochemical composition: A meta-analytical approach

Crop residue incorporation is a common practice to increase or restore organic matter stocks in agricultural soils. However, this practice often increases emissions of the powerful greenhouse gas nitrous oxide (N2O). Previous meta-analyses have linked various biochemical properties of crop residues to N2O emissions, but the relationships between these properties have been overlooked, hampering our ability to predict N2O emissions from specific residues. Here we combine comprehensive databases for N2O emissions from crop residues and crop residue biochemical characteristics with a random-meta-forest approach, to develop a predictive framework of crop residue effects on N2O emissions. On average, crop residue incorporation increased soil N2O emissions by 43% compared to residue removal, however crop residues led to both increases and reductions in N2O emissions. Crop residue effects on N2O emissions were best predicted by easily degradable fractions (i.e. water soluble carbon, soluble Van Soest fraction (NDS)), structural fractions and N returned with crop residues. The relationship between these biochemical properties and N2O emissions differed widely in terms of form and direction. However, due to the strong correlations among these properties, we were able to develop a simplified classification for crop residues based on the stage of physiological maturity of the plant at which the residue was generated. This maturity criteria provided the most robust and yet simple approach to categorize crop residues according to their potential to regulate N2O emissions. Immature residues (high water soluble carbon, soluble NDS and total N concentration, low relative cellulose, hemicellulose, lignin fractions, and low C:N ratio) strongly stimulated N2O emissions, whereas mature residues with opposite characteristics had marginal effects on N2O. The most important crop types belonging to the immature residue group – cover crops, grasslands and vegetables – are important for the delivery of multiple ecosystem services. Thus, these residues should be managed properly to avoid their potentially high N2O emissions.

The SDGs, Ecosystem Services and Cities: A Network Analysis of Current Research Innovation for Implementing Urban Sustainability

Ecosystem services are essential for cities and are key factors in achieving many of the Sustainable Development Goals (SDGs). Such services are best delivered through green infrastructure, which works in resourceful, multifunctional, synergistic, and environmentally sensitive ways to deliver ecosystem services and provide alternative cleaner pathways for the delivery of multiple urban services. It is unclear if current research supports the necessary linkages between ecosystem services, cities, and green infrastructure in order to achieve the SDGs. To answer this question, we conducted a systematic review analysing 3392 studies on the SDGs from the WoS database. The contents of 66 of those with relevance to ecosystem services and urban research were reviewed in depth. We applied network-analytic methods to map the relationships of different knowledge clusters of SDGs research (1) across time, (2) across disciplines, and (3) in relation to ecosystem services and cities. The results of our analysis show that research on the SDGs have developed stronger networks from 2010–2018, but this research has not been sustained. Further, whilst research on cities now occupies a central place in the SDGs literature, research on ecosystem services only shows tentative links to both green-infrastructure research and SDGs research. Such literature on urban green infrastructure remains peripheral to the central challenge of sustainable urban transitions. We conclude that when it comes to the SDGs, research articles typically consider urban services independently of green infrastructure. Further, it suggests that green infrastructure is not generally considered as a sustainable alternative to conventional urban infrastructures. To address this serious shortcoming, we recommend transdisciplinary approaches to link urban ecosystem and urban green infrastructure research to the 2030 global sustainability agenda.

Bats provide a critical ecosystem service by consuming a large diversity of agricultural pest insects

Biodiversity directly influences the delivery of multiple ecosystem services, most notably within agriculture. Projected future global demands for food, fiber and bioenergy will require enhancement of agricultural productivity, but favoring biodiversity-based ecosystem services generally remains underutilized in agricultural practice. In addition, agricultural intensification is a key driver of biodiversity loss. A significant obstacle preventing the adoption of ecologically sensitive practices is a lack of knowledge of the species delivering the services. Insectivorous bats have long been suggested to regulate insect pest populations and may be a critical component of biodiversity-based ecosystem services. Bats may also serve as agents of insect pest surveillance through environmental DNA (eDNA) monitoring approaches. However, the biological and economic importance of bats to agriculture remains under-quantified. Here we catalogued the dietary niche of two North American bats, little brown bat (Myotis lucifugus) and big brown bat (Eptesicus fuscus), through DNA metabarcoding of guano collected from seven roosting sites over a 26-week period. We measured the frequency of occurrence of known pest species in guano samples, compared interspecific differences in diet, and examined seasonal patterns in prey selection. Overall, we detected 653 unique prey species, 160 of which were known agricultural pests or disease vectors. Species diversity of prey species consumed varied by bat species and across the season, with big brown bats accounting for the majority of arthropod diversity detected. However, little brown bats consumed relatively more aquatic insects than big brown bats, suggesting that increased bat species richness in a landscape can amplify their net pest regulation service. Further, we hypothesized that detection probabilities of target insect pests would be higher in guano samples than in conventional survey methods. Multi-survey occupancy modeling revealed significantly lower detectability in bat guano than in conventional monitoring traps, however, highlighting important tradeoffs in selection of survey methods. Overall, the results presented here contribute to a growing evidence base supporting the role bats play in the provisioning of biodiversity-based ecosystem services.

Does agri-environmental management enhance biodiversity and multiple ecosystem services?: A farm-scale experiment

Agri-environmental management has been promoted as an approach to enhance delivery of multiple ecosystem services. Most agri-environment agreements include several actions that the farmer agrees to put in place. But, most studies have only considered how individual agri-environmental actions affect particular ecosystem services. Thus, there is little understanding of how the range of agri-environmental actions available to a farmer might be deployed on any individual farm to enhance multiple services. To address this knowledge gap, we carried out an experimental study in which we deployed a set of agri-environmental actions on a commercial farm in southern England. Agri-environmental actions comprised wildflower margins and fallow areas in arable fields, creating and enhancing grassland with wildflowers, and digging ponds. Alongside biodiversity responses, we measured effects on a number of ecosystem services: pollination, pest control, crop and forage yield, water quality, climate regulation and cultural services. Wildflower margins enhanced invertebrates, pest control and crop yield, and aesthetic appeal. A greater number of pollinators was linked to enhanced oilseed rape yield. But these margins and the fallows did not prevent run-off of nutrients and sediment into waterways, and showed limited carbon sequestration or reduction of greenhouse gas emissions. Newly-dug ponds captured large amounts of sediment and provided aesthetic appeal. Grasslands had higher soil carbon content and microbial biomass, lower N20 emissions, and net sequestration of carbon compared to arable land. Enhancement of grassland plant diversity increased forage quality and aesthetic appeal. Visitors and residents valued a range of agri-environmental features and biodiversity across the farm. Our findings suggest one cannot necessarily expect any particular agri-environmental action will enhance all of a hoped-for set of ecosystem services in any particular setting. A bet-hedging strategy would be for farmers to apply a suite of options to deliver a range of ecosystem service benefits, rather than assuming that one or two options will work as catch-all solutions.

Bundling ecosystem services at a high resolution in the UK: trade-offs and synergies in urban landscapes

ContextEcosystem service bundles can be defined as the spatial co-occurrence of ecosystem services in a landscape. The understanding of the delivery of multiple ecosystem services as bundles in urban areas is limited. This study modelled ecosystem services in an urban area comprising the towns of Milton Keynes, Bedford and Luton.ObjectivesThe objectives of this study were to assess (1) how ecosystem service bundles scale at a 2 m spatial resolution and (2) identify and analyse the composition of ecosystem service bundles.MethodsSix ecosystem services were modelled with the InVEST framework at a 2 m resolution. The correlations between ecosystem services were calculated using the Spearman rank correlation coefficient method. Principal Component Analysis and K-means cluster analysis were used to analyse the distributions, spatial trade-offs and synergies of multiple ecosystem services.ResultsThe results showed that regulating services had the tendency to form trade-offs and synergies. There was a significant tendency for trade-offs between supporting service Habitat quality and Pollinator abundance. Four bundle types were identified which showed specialised areas with prevalent soil erosion with high levels in water supply, areas with high values in nutrient retention, areas with high levels in carbon storage and urban areas with pollinator abundance.ConclusionsThis study demonstrates the existence of synergies and trade-offs between ecosystem services and the formation of ecosystem service bundles in urban areas. This study provides a better understanding of the interactions between services and improve the management choices in ecosystem service provision in urban and landscape planning.

Restoring farmlands for food and nature

Changes in the intensity and extent of farmland have a profound impact on life on Earth. Although nature-rich farmlands have conservation value, their promotion competes with the protection and restoration of natural habitat. Restoring the productive capacity of existing farmland can help maximize opportunities for the restoration of both nature-rich farmlands and natural habitat.

Ever and repeat HIV testing rates among male and female clients: Findings from a reproductive health services integration project in South Africa.

HIV testing rates have increased in recent years. Repeat testing is recommended to identify and treat new HIV infections timeously. However, there are limited data on repeat HIV testing, especially in South Africa (SA). To provide data on repeat HIV testing rates in males and females in a district in SA. A sexual and reproductive health (SRH) service integration model was implemented in seven healthcare facilities in eThekwini District, KwaZulu-Natal Province, SA, between 2009 and 2011. HIV testing data were collected from male and female clients attending these facilities, prior to (baseline) and after the implementation (endline) of the 3-year health services integration intervention. There were 230 clients at baseline (195 female, 35 male) and 200 at endline (169 female, 31 male). High ever-tested rates were reported at baseline (females 95.4%, males 74.3%) and endline (females 91.7%, males 87.1%), with large increases in male testing rates over time. In addition, high increases were seen between baseline and endline among those who had tested more than once and more than twice in their lifetime. Increases between baseline and endline testing rates were highest in HIV testing services (HTS) (37.0 - 93.3% for clients who had tested more than once, and 11.1 - 53.3% for those who had tested more than twice). HIV testing and repeat testing increased over time, especially in males and in HTS. Promotion and integration of SRH services are critical to facilitate improved health-seeking behaviour and HIV testing of both male and female clients. They are also important for continued access to HTS at multiple service delivery points.
