Bostin Value
āBostin Valueā was a pilot scheme aiming to improve fruit and vegetable consumption in a deprived neighborhood in the borough of Dudley, England. Research identified the need to address both supply and demand to encourage the target audience (parents/carers of young children) to consume more fruit and vegetables along with their children. Bostin Value improved supply through commissioning a local greengrocer to sell fresh fruit and vegetables twice a week at a local primary school. Promotions were used to encourage sales, including a loyalty card system, money off vouchers, and recipe cards. To increase demand, educational sessions were run at the school to improve parentās skills in cooking seasonal produce. Children at the school received tasting workshops to encourage them to try a variety of fruit and vegetables. Results saw the mean portions of fruit consumed weekly by parents significantly increase from 2.4 portions in April 2009 to 3.1 in July 2010. This was mirrored in children whose weekly portions increased from 2.6 to 3.7. The mean number of different fruits and vegetables tasted by children also increased significantly. </jats:p
Biophysical considerations in integrated catchment management : a modelling system for Northern Thailand
A trend in environmental modelling and policy making has been to move towards the
use of integrated assessment methodologies as a means of balancing what are most
usually multi-issue problems with multiple stakeholders. These methodologies are
particularly relevant for the management of water resources given the interdisciplinary
nature of water problems. This thesis presents a Biophysical Toolbox that integrates
models for assessment of the outcomes of biophysical scenarios of water and land use
options. Outcomes are measured in terms of environmental indicators that are outputs of
the models.
The Biophysical Toolbox is comprised of three modules - the CATCHCROP crop
model, a hydrologic module based on the IHACRES rainfall-runoff model, and a
modified Universal Soil Loss Equation (USLE) approach. The models were designed to
have the following features: basic data requirements with which to drive the models;
relatively low parameterisation requirements thus limiting problems with error
accumulation; physically plausible, and easily transferred to other catchments. The aim
with integrated models of this type is to be able to discriminate between, and be
confident about, the relative changes in indicator outputs.
The CATCHCROP crop model was applied to subcatchments of Mae Chaem in northern
Thailand to identify: the impact of land management options (irrigation, fertilisation and
bunding status) on model outputs; and the sensitivities of deep drainage, surface runoff,
and crop yield estimates to the values of CATCHCROP model parameters. Model
behaviour was shown to be plausible when the land management of the crop was varied.
Results of a sensitivity analysis demonstrated the considerable non-linearity in the
response of CATCHCROP outputs to parameter values, and identified which
parameters most influenced the behaviour of the model. Two parameters were found to
be substantially insensitive.
Estimates of potential erosion were sensitive to the choice of equations describing the
topographic and rainfall erosivity factors of the USLE. Despite this, the choice of
equations should not affect the utility of the Biophysical Toolbox where direction and relative values of indicators between scenanos are important. Similar values of the
erosion susceptibility term in the USLE were obtained for each land unit whether the
procedure was applied on each land unit or on a more detailed grid-basis.
Testing of the hydrologic model involved analysing: the performance of the
regionalisation methodology in predicting discharge; changes in hydrologic response
under forest cover changes; and sensitivities in the model outputs to changes in values
of CATCHCROP model parameters. The regionalisation procedure generally overestimated
annual discharge although is capable of capturing relative changes. As forest
cover decreases, the proportion of streamflow in the quick flow component increased,
annual and wet season discharge increased, and dry season discharge decreased. The
relative quick and slow flow volume components were strongly sensitive to changes in
forest cover. Six main parameters within the CATCHCROP model were identified as
greatly impacting the calculation of quick and slow flow components.
The Biophysical Toolbox was then used to examine deforestation, climate, and land
management scenarios for the Mae Uam subcatchment of the Mae Chaem catchment,
highlighting tradeoffs among indicators and raising questions about perceived impacts.
The main results of the scenarios can be summarised as: deforestation scenarios do not
greatly impact streamflow although increases in potential erosion are extreme; upland
rice and vegetable crops are particularly susceptible to 'unacceptable' rates of erosion
on steeply sloping lands; wet season crop yields are more dependant on plot fertility
than on irrigation or bunding status. Sensitivity analysis of the whole toolbox was also
performed. Despite potentially large impacts of CATCHCROP parameter changes on
the re-calculation of the hydrology parameters, this did not translate into large
differences in total seasonal discharge.
Comprehensive testing of the Biophysical Toolbox illustrated the potential, and the
plausible behaviour, of the toolbox for exploring aspects of land and water resource
management in catchments in northern Thailand. Most useful to improve confidence in
model performance would be further testing of the hydrologic module in instrumented
catchments that have undergone significant forest cover changes over the period of
hydrologic record
Developing Teacher Competencies for Problem-Based Learning Pedagogy and for Supporting Learning in Language-Minority Students
Teachers need to be able to design and implement problem-based learning (PBL) experiences to help students master the content and the processes in new mathematics and science education standards. Due to the changed population of learners within schools, it is also critically important that teachers in the elementary grades have the abilities to work effectively with English language learners (ELL). This article discusses the implementation of a major initiative by our teachers college to achieve both of these goals through Problem-Based Enhanced Language Learning (PBELL), which combines PBL, enhanced opportunities for language, and ELL methods. The implementation began with a small group of faculty members developing and piloting PBELL experiences, with coaching spread throughout the program. Our student-teachers are graduating with multiple opportunities to experience PBELL as learners and to design and implement PBELL experiences
Course-based Science Research Promotes Learning in Diverse Students at Diverse Institutions
Course-based research experiences (CREs) are powerful strategies for spreading learning and improving persistence for all students, both science majors and nonscience majors. Here we address the crucial components of CREs (context, discovery, ownership, iteration, communication, presentation) found across a broad range of such courses at a variety of academic institutions. We also address how the design of a CRE should vary according to the background of student participants; no single CRE format is perfect. We provide a framework for implementing CREs across multiple institutional types and several disciplines throughout the typical four years of undergraduate work, designed to a variety of student backgrounds. Our experiences implementing CREs also provide guidance on overcoming barriers to their implementation
Integrated Modelling for Understanding Watershed Development Impacts on Social and Biophysical Systems
The intention of watershed development (WD) programs in India is to improve the livelihoods of people and preserve the natural resource base, particularly in areas where water scarcity limits the development potential of rural communities. In practice, there are many complications to implementing WD programs in an effective and equitable way for all people within and between villages in a catchment. Our understanding of the potential implications of a program is often limited by the way in which we investigate the biophysical-social-economic system. Two common failings are (a) not properly considering the importance of the place, scope and scale of a problem and (b) using a disciplinary approach to make conclusions about the system as a whole. This paper discusses how we are addressing these issues as part of an integrated assessment project looking at WD in the state of Andhra Pradesh, India. The multi-disciplinary project team includes agronomists, economists, environmental modellers, groundwater and surface water hydrologists, and social scientists who together are aiming to develop a holistic understanding of the impacts of WD on biophysical, social and economic systems. Key to the project philosophy is the inclusion of government representatives, communities, and non-government organisations (NGOs) in developing the researchers\u27 understanding of the issues and complexities associated with WD and the critical questions that need addressing by the project. An integrated model is being developed that will incorporate crop production water use and hydrological (surface water and groundwater) models in addition to knowledge gained from extensive household surveys in villages in two case study catchments. The household surveys were developed based on discussions with NGOs working with the rural communities in Andhra Pradesh and are being used to examine economic and social outcomes (positive and negative) of WD for households. Measures of equity and resilience are being developed to measure differences in outcomes between villages (e.g. upstream, downstream) and within villages (e.g. income groups, gender, land ownership, etc)
An integrated approach to improving rural livelihoods: Examples from India and Bangladesh
This paper presents an overview of work in West Bengal, Andhra Pradesh and SW Bangladesh through a series of projects from 2005 to the present, considering the impact of farming systems, water shed development and/or agricultural intensification on livelihoods in selected rural areas of India and Bangladesh. The projects spanned a range of scales spanning from the village scale (ā¼āāÆ1āÆkm2) to the meso-scale (ā¼āāÆ100āÆkm2), and considered social as well as biophysical aspects. They focused mainly on the food and water part of the food-water-energy nexus. These projects were in collaboration with a range of organisations in India and Bangladesh, including NGOs, universities, and government research organisations and departments. The projects were part funded by the Australian Centre for International Agricultural Research, and built on other projects that have been undertaken within the region. An element of each of these projects was to understand how the hydrological cycle could be managed sustainably to improve agricultural systems and livelihoods of marginal groups. As such, they evaluated appropriate technology that is generally not dependent on high-energy inputs (mechanisation). This includes assessing the availability of water, and identifying potential water resources that have not been developed; understanding current agricultural systems and investigating ways of improving water use efficiency; and understanding social dynamics of the affected communities including the potential opportunities and negative impacts of watershed development and agricultural development.he authors acknowledge funding from

Reflecting on integrated assessment in the Socially Inclusive Agricultural Intensification (SIAGI) project
Agricultural aide interventions are often intended to help small and marginal farmer households increase their agricultural production, and by doing so, better meet their household needs and improve their social and economic standing. However, intensifying their agricultural production requires them to have the capital assets (financial, human, natural, physical and social) and agency to access and use more agricultural inputs, develop and manage the necessary farm or community level infrastructure (e.g. for irrigation, or post-harvesting), and make informed crop and land management choices. Many small and marginalised farmers are lacking in both capital and agency, which constrains their capacity to engage in, and benefit from, agricultural intensification. In this paper, we reflect on our integration research in the 'Promoting Socially Inclusive and sustainable Agricultural Intensification in West Bengal and Bangladesh' (SIAGI) project, focusing on the learnings and outcomes of being socially inclusive in our modelling practices. The Ethical Community Engagement (ECE) ethos and practice to which the SIAGI project team has committed has shaped the content of the integrated assessment frameworks that we have developed as well as the process (Figure 1) we used to develop them. Social inclusion is both a core value of the SIAGI project and an outcome against which the impact of the project will be measured
