Landholder participation in native vegetation management in irrigation areas

Summary Landholder adoption of conservation practices has been extensively researched in dryland areas, but there has been less research into the adoption of biodiversity conservation practices in irrigation areas. The Murray Catchment Management Authority (MCMA) and Murray Irrigation Limited (MIL) in south‐west New South Wales offer landholders monetary incentives to enhance native vegetation management. However, uptake of the incentives and recommended practices has been slower in the irrigation areas than in dryland areas serviced by the MCMA. We explored landholder participation in native vegetation management in the MIL area using semistructured interviews with landholders and extension staff. Our findings suggest there are important differences between irrigation and dryland contexts. Landholders in irrigation districts face higher opportunity costs and are more likely to mistrust government intentions. Other constraints to adoption include lack of financial resources, restricted time to carry out works and a high turnover of extension staff. Landholders adopted recommended vegetation management practices because those practices matched their values and goals. The importance of regular contact with a positive and enthusiastic extension officer was also evident. These findings have important implications for conservation policies and programs. Extension should move beyond arousing interest and include substantial follow‐up contact to maintain landholder motivation and confidence, as well as provide recognition for past landholder efforts. Incentive programs should be designed to provide wider landholder support with different entry points allowing participants to adapt, learn and build confidence. Incentives should address the constraints experienced by landholders, particularly at times of peak workloads and during drought. Work targets set for field staff can be too high and result in program staff focusing on accomplishing on‐ground work, rather than developing irrigators’ longer‐term commitment to vegetation conservation.     

Same river,different values and why it matters

Summary Examination of the values that people assign to specific natural places is likely to be useful for environmental decision‐making but is an underdeveloped area of socio‐psychological research. A mail survey was used to examine the differences and similarities in values assigned by people to the Loddon River in south‐eastern Australia. Environmental, social and economic values were explored across five different community types: urban residents, rural residents, natural resource management (NRM) professionals, environmental group members (EGM) and landholders. While urban residents, rural residents and landholders had similar responses, NRM professionals and EGM placed much stronger emphasis on environmental values derived from the river, and much less emphasis on economic values. Members of two community types (EGM and NRM professionals) responded in a relatively homogenous way, within a narrow range of response options. By contrast, three community types (urban residents, rural residents and landholders) responded in more diverse ways. There were similarities in the social values (historical and aesthetic) expressed by the different community types, suggesting common points for stakeholder engagement in the management of the river. Results point to the need for environmental managers to ensure that consultation is not limited to the most actively engaged sectors of the community, as their responses may not be representative of other groups.     

Measuring riparian condition: A comparison of assessments by landholders and scientists

Summary   To a large extent, the condition of riparian areas in Australia is determined by the management actions of private landholders. In this study, we discuss findings from our research in the Goulburn Broken Catchment comparing landholder and scientist assessments of the condition of riparian areas. We interviewed 33 landholders and undertook ecological condition assessments at 38 sites on privately managed river frontages. Using mail survey data that included landholder assessments of riparian condition, we were then able to compare landholder and scientist assessments. Despite substantial effort in this catchment to improve riparian condition, the riparian zones sampled were generally in poor condition. Landholder and scientist assessments of ecological condition showed a significant positive correlation. This indicated broad agreement, despite some substantial differences in assessment of some components of the condition score. Disparities between scientist and landholder assessments were related to the estimation of native ground cover, leaf litter cover and tree canopy continuity within riparian zones. The capacity of this simple assessment tool to differentiate varying levels of riparian zone degradation demonstrates the potential utility of mailed, self-assessment surveys to inform management programs and decisions about the allocation of resources for restoration efforts.     

Remnant vegetation,landholders’ values and information needs: An exploratory study in the West Australian wheatbelt

Summary An exploratory study of landholders in the central wheatbelt of Western Australia provides a useful snapshot of values, uses, management, information sources and requirements of landholders in relation to remnant native vegetation in agricultural landscapes. Landholders valued their remnant vegetation for ecological, aesthetic, functional and community reasons. Most actively managed it for nature conservation, although almost half grazed stock in their remnants. In terms of information sources and needs, the most widely used sources were Community Landcare Coordinators, other landholders and government departments. Landholders wanted hydrological, weed control and biodiversity information, plus a suite of other information. A third of landholders were characterized as having a broad, ecosystem‐based awareness compared to the other two‐thirds who had a more limited, site‐based awareness. Each group had different information needs. These findings have clear implications for information provision to landholders.     

Using landholder perspectives to evaluate and improve recovery planning for Toolibin Lake in the West Australian wheatbelt

Summary Over the last two decades, recovery plans have emerged as one of the most widespread policy and management responses for endangered species. Often these plans include public and private lands, and the associated government departments and private landholders. Toolibin Lake, in the West Australian (WA) wheatbelt, is a case in point, with a recovery plan focused on an internationally recognized wetland on public land within a predominantly privately owned, agricultural catchment. This paper draws on recent questionnaire and interview‐based research with landholders, to evaluate the influence of the recovery plan on conservation activities. Almost all landholders in the Catchment (93%) are involved in revegetation activities, with the availability of subsidies from the WA Government playing a strong role in adoption and its extent. The main constraints to adopting conservation actions, such as revegetation and fencing remnant vegetation, were cost and logistics. Correspondingly, the greatest incentive was financial inducement. Strengths of the recovery plan were identified as increasing awareness, demonstrating government effectiveness, and making funding available to landholders. The communication efforts by the WA Department of Conservation and Land Management (CALM), the agency leading the recovery process, were lauded while at the same time the need for improved liaison was noted. Weaknesses were the lack of information and direction from CALM, bureaucracy, limited funding for CALM, and variable adoption across the Catchment. Recovery planning in this Catchment and other similar settings could be improved by a continuing commitment to two‐way communication between all those involved, ongoing recognition of the complexities of the government–community interface in recovery planning, and continuing subsidies for conservation actions on private lands where high biodiversity values are at stake.     

Factors influencing smallholder orange farmers for compliance with GobalGAP standards

The inability of farmers to comply with global good agricultural practices (GlobalGAP) standards has led to food safety issues harmful to human health and sustainable agriculture. This study aimed to assess the extent of GlobalGAP compliance among orange farmers and investigate barriers associated with compliance. Data were collected with structured questionnaires from 238 orange farmers. The findings showed that the farmers’ rate of adherence to the GlobalGAP standards was moderate (mean 3.58). Using factor analysis, the following four groups were identified as key barriers to compliance: personal and economic barriers, awareness and information barriers, institutional-support barriers, and infrastructure barriers. Institutional support barriers were deemed most important by farmers in compliance decisions (mean 4.29), followed by personal and economic barriers (mean 3.89). Therefore, a focus on the barriers faced by smallholder farmers would be crucial to improve their adoption of food safety standards. This can enhance the quality of agricultural commodities, customers’ safety, and the livelihood of smallholder farmers.     

Responses of grassland ecosystems to precipitation and land use along the Northeast China Transect

Abstracts. The Northeast China Transect (NECT) has been used to study how water availability influences the composition of plant functional types, soil organic matter, net primary production, trace gas flux, and land‐use patterns. We discuss relations of plant species number, soil C and N and above‐ground biomass with a precipitation gradient and interactions with land‐use practices (grassland fencing, mowing and grazing), on the basis of data from the west part of NECT. The results indicate: 1. The above‐ground biomass of grassland communities has a linear relationship with precipitation under three land‐use practices, while plant species number, soil C, and total soil N have linear relationships with precipitation under fencing and mowing; under grazing the relationships are non‐linear. 2. Plant species number, soil C and total soil N have strong linear relationships with above‐ground biomass under both fencing and mowing, while they seem to have nonlinear relationships under grazing. 3. Land‐use practices along the precipitation gradient result not only in changes in grassland communities but also in qualitative changes of their structure and function. 4. Grasslands are more vulnerable to changes in climate under mowing than under fencing, and are more capable to store C in soil and plants. 5. At a given precipitation level, number of plant species, above‐ground biomass, and soil C are higher under low to medium intensity of human activities (mowing and grazing). A better understanding of how different intensities of human activities will affect the structure and function of grassland will require further research.     

Traditional Maize Storage Methods of Mayan Farmers in Yucatan, Mexico: Implications for Seed Selection and Crop Diversity

For small-scale farmers who maintain genetically diverse crop populations, aspects of the storage of their seeds and harvest may be just as important for successful farming as those related to productivity. The community of Yaxcaba, Yucatan, Mexico was studied to understand how the conditions under which Maya farmers store their maize harvests influence their seed selection practices and the diversity of maize varieties grown. Most farmers select their maize seed based primarily on ear characteristics and secondarily on grain characters. Farmers incorporate storability concerns by selecting for an archetypal healthy ear and by conducting selection in several steps between harvest and planting of the subsequent crop generation. Most farmers store their maize harvest in the husk, initially in the field and then in rustic granaries constructed of logs and palm thatch, in which farmers conserve separately their different seed lots. All local landrace populations show morphological adaptation (principally husk characteristics) for local storage conditions, indicating that storability has been an important selection pressure on traditional maize. Storability also appears to be a key factor working against the straightforward adoption of improved maize seed in Yaxcaba. Local farmers value many qualities of improved maize varieties, but their principal complaint is that improved maize cannot be conserved reliably under local storage conditions. Nearly all farmers who utilize improved seed stock in Yaxcaba grow locally adapted or ‘creolized’ versions of improved varieties, displaying characteristics of local maize landraces that facilitate their storage.     

Fox‐baiting in agricultural landscapes in south‐eastern Australia: a case‐study appraisal and suggestions for improvement

Summary In south‐eastern Australia, the introduced Red Fox (Vulpes vulpes) is a major predator of native wildlife and livestock. Fox control in agricultural landscapes is heavily reliant on the laying of poisoned baits by private landholders, yet there have been few assessments of the application or success of landholder‐baiting practices. We evaluated a community‐based fox‐baiting campaign, typical of programs employed throughout the agricultural regions of south‐eastern Australia to control foxes. We recorded the spatial coverage of 1080 baits deployed by landholders, assessed baiting procedures, monitored the survival of six radio‐collared foxes during and after baiting, and compared the spatial coverage and likely effectiveness of the baiting program with two alternative (theoretical) baiting strategies. Relative to other baiting programs, coordination among neighbours was reasonably high, with 37.5% of baited properties (n = 40) adjoining ≥3 neighbouring properties that also contained baits. Nevertheless, the maximum distance from the centre of a baited property to the nearest edge of an unbaited property was <750 m (mean = 380 m ± 147 m SD). On average, 33% (±17% SD) of each fox’s home range overlapped with baited properties, but only two foxes died during the baiting program. The remaining four foxes were still alive 10 weeks after baiting ceased. Modelling of simulated fox home ranges showed that 13.5% contained no bait stations based on the community baiting program, whereas alternative roadside‐ and grid‐baiting strategies (theoretically) delivered baits to all simulated home ranges. Some landholders employed practices that could reduce the effectiveness of baiting programs such as not removing decayed baits before deploying new ones or placing bait stations too close together. Our research illustrates the difficulties of managing a coordinated baiting program on private land that effectively controls foxes. Alternative baiting strategies such as roadside baiting need to be considered to improve fox control in agricultural landscapes.

Effect of fencing and grazing on a Kobresia-dominated meadow in the Qinghai-Tibetan Plateau

Grazing is one of the most important factors influencing community structure and productivity in natural grasslands. Fencing to exclude grazers is one of the main management practices used to protect grasslands. Can fencing improve grassland community status by restraining grazing? We conducted a field community study and indoor soil analyses to determine the long-term effects of fencing and grazing on the above-ground community and soil in a Kobresia-dominated meadow in the Qinghai-Tibetan Plateau, NW China. Our results showed that fencing significantly improved above-ground vegetation productivity but reduced plant density and species diversity. Long-term fencing favored the improvement of forage grass functional groups and restrained the development noxious weed functional groups. There were significant positive effects of fencing on below-ground organic matter, total nitrogen, available nitrogen, total phosphorus and available phosphorus. The productivity of grazed meadow showed a weak decrease over time. There were long-term decreasing trends for plant density both in fenced and grazed meadows. Our study suggests that grazing can be considered as a useful management practice to improve species diversity and plant density in long-term fenced grasslands and that periodic grazing and fencing is beneficial in grassland management.     

Participatory Research Approaches and Social Dynamics that Influence Agricultural Practices to Improve Child Nutrition in Malawi

The Soils, Food and Healthy Communities project in Malawi uses an interdisciplinary participatory approach to improving child nutrition with resource-poor farmers. The overall research question is: Can legume systems improve soil fertility, food security, and child nutrition? Over 2000 farmers are now experimenting with legume systems in the region. While this article examines the social issues that mitigate the potential success of legume options tested by the farmers, it does not aim at discussing extensively the complex web of interactions between soil fertility, food security, and nutritional status of children. Instead, its focus is on the research process, and more specifically on the social dimensions and participatory approaches, which influenced farmers’ adoption of organic matter technologies and legume options. The Farmer Research Team was critical in mobilizing community interest in changing agricultural practices to improve child health, but faced challenges in village politics and workload. The linkage with child nutrition was a major reason for increased adoption of legumes, and gender relations played a key role in the adoption. A deeper understanding of the limits of participatory approaches helped to develop innovations that may be replicated elsewhere, such as inclusion of grandmothers and a farmer apprenticeship program.     

Environmental issues in relation to agricultural practices and attitudes of farmers: A case study from Saudi Arabia

PurposeThe Kingdom of Saudi Arabia is continuously in search of environment-friendly farming practices since mass-scale agriculture was initiated. It is imperative to gauge to the level of awareness of the farmers on the agricultural practices causing environmental issue in order to devise new agricultural extension programs. This research aims to identify the attitudes of farmers towards agriculture and environment in Al-Ghat area of Saudi Arabia.MethodologyA simple random sample of 110 farms truly representing the farming community was drawn to meet the objectives of the study. Data were collected by using the pre-tested questionnaire during the face-to-face interviews. In order to understand the message of study, data were analyzed for percentages, arithmetic average and standard deviation in addition to the simple Pearson correlation coefficient.ResultsThe results showed that the high proportion (87.3%) of farmers was interested in continuing to work farm and 77.3% of farmers did not consider adopting agriculture their main occupation. The findings of the survey reveal that some 55.5% of the respondent farmers were aware of the agricultural practices and their relation to the environment. Some 57.3% of the surveyed farmers are aware of potential benefits of enhanced utilization of agricultural organic wastes. However, main profession, farm employment (as the independent variables) showed a significant positive correlation with the attitudes of farmers towards their working in agriculture (as a dependent variable). Also a significant negative relationship between the educational levels and the attitudes of the farmers towards working in agriculture was noticed. The study also indicated a significant correlation between education and the degree of awareness of agricultural practices related to the environment and maximizing the optimum utilization of agricultural waste i.e. organic residues.ConclusionsThe study suggested the need for new awareness and orientation programs to educate farmers and extension workers, highlighting the environment- friendly agricultural practices.Recommendation: There is need to offer incentives and facilities to keep the farmers stay in the farming business. Extension staff must keep educating them on beneficial features of organic farm waste and crop residues as organic fertilizers.     

Adoption of Policy Incentives and Land Use: Lessons From Frontier Agriculture in Southeastern Peru

Literature on environmental change often highlights the importance of public policies as a key driver of land use and land cover change. However, demonstration of policy impacts in agricultural settings has been hampered by the lack of systematic analysis across landholders, who may not universally adopt government policy incentives, or time periods, which may be associated with differing policy regimes. This paper evaluates the importance of voluntary adoption of policy incentives offered by Peruvian government administrations over two decades for land-use among small farmers in the Peruvian Amazon. The analysis focuses on whether farmers adopted one or more policy incentives in order to observe the effects on land uses including mature forest, agricultural crops, cattle pasture, and secondary growth. We employ multivariate statistical models to estimate the effects of policy adoption while controlling for other factors. The findings show that distinct policies are associated with particular land-uses and largely follow expectations. Specifying policy incentives promulgated by governments and differentiating among adopters and non-adopters advances understanding of the impacts of public policies on land use.     

Australia’s Stock Route Network: 2. Representation of fertile landscapes

The Stock Route Network (SRN) of New South Wales (NSW) and Queensland is a large‐scale system of predominantly roadside remnant vegetation, which was established in the 1800s to allow livestock to be moved. Proposed changes to the management of the SRN could result in some portions of it being sold to private landholders, or subjected to long‐term set‐stocking. This may have potentially negative impacts on some of the values of the SRN. One key feature of the SRN is that it covers low‐lying parts of the landscape, which are poorly protected by national parks. To quantify this, we specifically analysed a 41 million hectare portion of the SRN which transects the NSW ‘wheat‐sheep belt’, characterising its representation of woody vegetation cover and topography, and contrasting this with the National Reserve System. Our analysis revealed that 55% of stock routes occur in low‐lying valley portions of the landscape, compared with only 6% of the National Reserve System. The SRN supports a wide range of vegetation types and, unlike the National Reserve System, is not biased towards heavily forested areas. White Box‐Yellow Box‐Blakeley’s Red Gum woodland, which is listed as critically endangered by the Australian Government, was recorded in 803 (or 17.5%) of the 4575 stock routes in our data set. In contrast, only 10 of the 335 reserves within our spatial study region are known to support small occurrences of this community. Our findings suggest that the protection of the SRN and National Reserve System together may fulfil the ‘representation’ goal of systematic conservation planning far better than the National Reserve System on its own. Future research should quantify which stock routes in particular should receive priority for protection.     

The Financial Costs of Ecologically Nonsustainable Farming Practices in a Semiarid System

Nonsustainable ostrich farming practices have degraded large areas of the Little Karoo, a semiarid region in South Africa. The Little Karoo lies within the Succulent Karoo biome, a recognized biodiversity hotspot. A financial feasibility analysis was undertaken from a private landowner’s perspective to examine the costs and benefits of rehabilitating degraded areas thereby allowing farmers to shift their production focus from ostrich to sheep farming, a financially stable and relatively conservation‐compatible land use. Our aim was to raise awareness, at a private landowner level, to the opportunity costs incurred through unsustainable land use practices. We calculated and contrasted net present values for rehabilitation and no rehabilitation scenarios and investigated model sensitivities relating to seed costs, seedling survival and ostrich product prices. Rehabilitation was not found to be financially feasible for private landholders over 20 years. Seedling survival and associated seed costs were found to have strong controlling effects. Third parties need to contribute both financially and in terms of research outputs if sustainable land use practices are to be achieved in this area. This study elucidates the true costs associated with the unsustainable practice of ostrich farming and sounds a cautionary warning.     

Effects of different fencing regimes on community structure of degraded desert grasslands on Mu Us desert,China

Grazing is one of the major anthropogenic driving factors influencing community structure and ecological function of grasslands. Fencing has been proved to be one of the main measures for rehabilitating degraded grasslands in northwestern China. However, data from combined empirical studies on the effects of different management regimes in desert grasslands are lacking. So we selected long‐term fencing (fenced since 1991), mid‐term fencing and seasonal fencing (fenced since 2002), and adjacent free‐grazing grasslands to investigate vegetation and soil properties on southwest Mu Us desert. Our results showed that fencing increased plant cover, height, aboveground biomass (AGB) of different plant life‐form groups, Shannon–Wiener diversity index, Evenness index, Simpson index, total soil nitrogen, total soil phosphorus, and soil organic matter, but decreased plant density, species richness, Richness index, soil bulk density, water content, and pH. However, 22–24 years of long‐term complete fencing might cause redegradation of vegetation and soil nutrients, characterized by the reduction of some vegetation properties, biodiversity, total AGB, and some soil properties. Seasonal fencing with 11–13 year was more beneficial to vegetation restoration than that with completely fencing measures. Our study suggests that appropriate artificial disturbances, such as seasonal fencing (winter grazing and summer fencing), should be used after long‐term fencing in order to maintain grassland productivity and biodiversity. These findings will help to provide theoretical support for vegetation restoration and sustainable management in grassland under grazing prohibition at Mu Us desert.     

Farmers' perspectives for the development of a bioenergy industry in Ireland

A survey of Irish farmers was conducted to identify farmers’ opinions on energy crop production and to characterize potential adopters of energy crop cultivation in Ireland. One hundred and seventy‐two surveys were completed from 25 counties in Ireland. Miscanthus (48%) and grass (30%) were the preferred crops for adoption of energy crop production. Potential adopters described themselves as having a significantly greater level of knowledge of energy crop production compared with other respondents. The results indicate that lack of interest in adopting energy crop production may be due to lack of knowledge regarding the economic benefits of adoption and the variety of energy crops available for cultivation in Ireland. The establishment of long‐term contracts and government schemes were identified as important requirements for the development of bioenergy crop production in Ireland. Energy crop adoption was not limited to farmers undertaking specific farm enterprises. Farmers were motivated to adopt energy crop production for both economic and environmental benefits. These results are the first to provide valuable information on the perspectives of potential adopters of bioenergy crop production in Ireland for the promotion and implementation of a national bioenergy industry. Policy requirements and outreach strategies to encourage adoption of energy crops by agricultural producers are suggested.     

Litter accumulation alters the abiotic environment and drives community successional changes in two fenced grasslands in Inner Mongolia

Fencing is an effective and practical method for restoring degraded grasslands in northern China. However, little is known about the role of excess litter accumulation due to long‐term fencing in regulating abiotic environment and driving changes in community structure and function. We conducted a three‐year field experiment in two fenced grasslands in Inner Mongolia, and monitored light quantity, soil temperature, and soil moisture continuously, and determined community height, community aboveground net primary productivity (ANPP), and the relative dominance of different plant functional groups. Litter accumulation reduced light quantity and soil temperature but increased soil moisture. The regulating effects of litter accumulation on soil temperature and soil moisture fluctuated temporally and gradually weakened over the growing season. Litter accumulation also altered community vertical structure and function by increasing community height and ANPP. The increase in soil moisture increased the relative dominance of rhizome grasses but suppressed bunch grasses, thereby shifting bunch grass grasslands to rhizome grass grasslands. Our findings provide a potential mechanism for community succession in the context of litter accumulation in fenced grasslands and indicate that the vegetation and ecosystem services of degraded grasslands are improved after appropriate fencing.     

Attitudes of European farmers towards GM crop adoption

This article analyses European Union (EU) farmers' attitudes towards adoption of genetically modified crops by identifying and classifying groups of farmers. Cluster analysis provided two groups of farmers allowing us to classify farmers into potential adopters or rejecters of genetically modified herbicide-tolerant (GMHT) crops. Results showed that economic issues such as the guarantee of a higher income and the reduction of weed control costs are the most encouraging reasons for potential adopters and rejecters of GMHT crops. This article also examines how putting in place measures to ensure coexistence between GM and non-GM crops may influence farmers' attitudes towards GMHT crop adoption. Results show that the implementation of a coexistence policy would have a negative impact on farmers' attitudes on adoption and consequently may hamper GMHT adoption in the EU.
