The purpose of this paper is to explore enterprise diversification amongst wetland farmers in Zambia as a way of reducing poverty and improving sustainability. This paper identifies ways in which such entrepreneurial activities can be supported and applied more widely.

A qualitative study of Zambian farmers, based on a series of workshops and interviews held in Zambia with farmers and farm business advisers.

Despite adopting new technologies most farmers are restricted to the local market where their increased production holds down prices. However, a very small number of farmers are able to progress to production and marketing for markets in major urban centres hundreds of kilometres away, and considerably more are able to use the capital accumulated from wetland farming to diversify their household enterprises to reduce poverty and improve the sustainability and resilience of their livelihoods.

No work has previously been undertaken in diversification strategies of small-scale farmers in Zambia.

The purpose of this paper is to analyse aspects of technological change in rice agriculture, related to adoption of the Green Revolution (GR) in Indonesia. Rice production is selected in this study because it plays an important role in the development of Indonesian economy. Particular attention is paid to the use of agrochemicals that has potentials of contaminating the environment.

The paper uses an econometric model to investigate the impact of different technologies and policies related to rice production. Production function technology that enables non-neutrality of input use is the underlying concept of this paper. Types of land and transformation in policies related to rice production were accounted for to determine biased technological change. National-wide data were compiled from the Indonesian Bureau of Statistics.

The results show that rice agriculture underwent technological progress with biased technological change. The technological change was capital- and labour-saving, and agrochemical-augmenting. Production system in wetland led to technological change less capital- and labour-intensive, whilst the GR led to technological change more labour-saving and more agrochemical-augmenting.

This study only pays attention to environmentally detrimental inputs as a cause of externalities. This is a not full representation of real environmental consequences. In some studies on environmental degradation associated with intensive agricultural practices, however, there are other factors that can degrade the environment, such as soil erosion and soil compaction resulting from certain agricultural practices, and deforestation resulting from agricultural expansion. These are also important environmental impacts. The author expects that these factors are interesting and challenging subjects to be modelled in future research on sustainability of agricultural productivity growth, both theoretically and empirically.

Increase in use of agrochemicals was strongly GR linked. Moving from the GR towards more environmentally friendly policy was a wise step to reach sustainable rice production. After the GR, an act that removed pesticide subsidies and disseminated environmentally friendly technology, called integrated pest management was able to reduce the intensity of agrochemical use in rice agriculture. Further actions to support environmentally friendly policy could be the use of bio-agents such as bio-fertilisers and bio-pesticides. Enhancing farmers’ knowledge on the environmental issues and engaging farmers as a part of agro-ecosystem would synergise the actions.

This study uses the concept of biased technological change, estimated econometrically using national-level data. The production function used in this analysis enables non-neutrality of agrochemical use. When the result significantly shows the agrochemical-augmenting technological change, it is a convincing evidence, not just by accident, that the GR really led to environmental problem.

This study aims at identifying the consequences of adopting statutory rather than market basis in assessing damages due to contamination to land. Most valuations undertaken to assess compensation for damages due to contamination on land are done with valuation methods prescribed by law for the compulsory acquisition of land.

A total of 80 registered valuation firms with experience in both compulsory acquisition and damage assessment participated in a questionnaire survey to ascertain the methods adopted in valuing when determining the compensation payable as damages due to land contamination and the need for a framework for such valuations, in addition to some archival documents relating to the relevant laws and some purposively selected valuation reports, which were reviewed.

The results of the analysis indicate that the use of compulsory acquisition valuation methods results in inadequate damages, which engenders conflicts among the stakeholders. The absence of any framework for damage assessment is responsible for the current practice in the Niger Delta, and it is recommended that international best practices utilising market basis of valuation be adopted.

Most valuation methods available are useful for valuing commercial properties regularly traded in the market and not applicable to the Niger Delta, which is mostly rural with very few market transactions. It is expected that this study will enable oil and gas industry operators, professional valuers advising the land owners or operators in the industry and the government to differentiate compensation paid for compulsory acquisition and compensation required to placate those suffering losses due to contamination.

The findings will assist professional valuers to be more professional in valuing contaminated land devastated by oil spills.

Adopting the findings will engender a greater acceptability of the results of valuations undertaken in the wake of an oil spillage disaster and ensure a peaceful environment for the oil operators and the entire populace.

The findings of this study are expected to assist policymakers in emerging economies and professional valuers acting in these environments to avoid precipitating crises by adopting inappropriate valuation techniques when assessing damages due to contamination. This study is original and has not been published elsewhere.

A wetland is a place of tourist attraction, and tourism values play a key role in economic development. Among various services provided by a wetland, recreational services are increasingly valuable in the tourism sector. This paper aims to unfold the potential recreational values of the Dal Lake in Jammu and Kashmir, India.

The study uses individual travel cost methods (TCMs) and assesses its impact on regional development in terms of income and employment generation. A sample of 200 tourists is selected through an on-site survey on Dal Lake, and the demand for recreational visits and its value is estimated by employing the truncated Poisson regression model (TPRM) and un-truncated Poisson regression model (UTPRM). The consumers' surplus is estimated and tourists' benefit to visiting the wetland is explored.

On average, estimated consumers' surplus per visitor is Rs 6,250 (US$96.15) and Rs 25,000 (US$384.61) from respective models. The annual total recreational value of the lake is accounted for Rs 1713m (US$ 26m). This high consumer surplus (CS) and recreational values of the lake indicate large demand for its recreational facilities.

The study is based on primary data and thus, is original. The paper has implications for the policymakers to formulate sustainable management plans for the proper use of Dal Lake and tourism development.

This paper examines the performance of smallholder rice farms established using improved planting technologies – broadcasting, dibbling and transplanting – under different production systems – rain-fed and irrigation – in Ghana.

Using recent cross-sectional data of 200 smallholder rice farmers from the upper east region of Ghana, this study employed multinomial logit model and descriptive and inferential statistics for the analysis.

The results revealed that rice production under irrigation system contributes significantly to increasing farm productivity and profitability. Rice farmers who adopted dibbling and transplanting technologies under both irrigation and rain-fed production system obtained higher productivity and profitability than those who used broadcasting technology. Adoption of improved rice planting technologies by smallholder farmers is significantly influenced by education, farm size, improved rice varieties, sales outlets, hired labour and percentage of paddy sold.

The sample size is relatively small, even though findings are still very important in terms of policy formulation for improved smallholder farm performance in a developing country like Ghana.

This study calls for collaborative efforts by government, donor agencies and NGOs to establish irrigation facilities and/or expand existing ones, increase sensitization and dissemination of improved planting technologies, as well as intensify the input subsidy programme in Ghana.

To the best of the authors knowledge, this is the first study that focuses on farmers' choice of rice planting technologies under irrigation and rain-fed production systems, and how these technologies impact on smallholder farm performance in Ghana.

This paper generally aimed to evaluate the knowledge of rural farmers towards climate change (CC) and their adaptation practices as a way of reducing the vulnerability in different agro-ecological zones (AEZs) of Tanzania. This establishment is quite important because rural farmers are most vulnerable to impacts of CC. Therefore, there is a need to establish the actual knowledge on this aspect in order to meet the urgency for action on CC by using the endowed environmental resources. This knowledge will assist policy makers and CC practitioners.

This study employed systematic and simple random sampling procedures in selecting the districts and villages as study sites. It used both quantitative and qualitative data sets derived from climatic records, questionnaires survey, interviews and discussion. The Mann-Kendall test and Sen's slope, and theme content were used for data analyses.

The results exhibited that most farmers have been greatly adapting to CC through numerous and well-known practices. However, there has been adoption of other new practices mainly influenced by new knowledge from extension services, environmental endowments and temporal environmental change. Although there has been varied perceptions on CC, the results indicate that most farmers (>70%) are aware of the changing climate and their knowledge corresponds to meteorological data.

Most farmers perceived that prolonged drought and erratic rains are the main indicators of CC. These indicators were the base of copping and adaptation mechanisms. Despite this, there is a need for all climate practitioners to join hands in improving the existing adaptation practices that can limit climate impacts in local areas.

This paper aims to examine the planning policy and legal framework governing the creation and operation of urban agriculture in Sydney, Australia’s global city. All levels of urban agriculture are considered – from domestic and small community gardens to large agribusiness – as all make an important contribution to agricultural production in an urban context.

Using the Australian State of New South Wales and its capital Sydney, as a focus, the study examines the recent trend of the recognition and re-establishment of agriculture as a desired land use in cities. Three examples are selected for closer scrutiny – Horsley Park Urban Agriculture Precinct, located in the Western Sydney Parklands; City of Sydney’s City Farm, located in the inner suburb of St Peters; and the Western Sydney Aerotropolis Agribusiness Precinct, located at a new airport on the fringe of Sydney.

As more city-dwellers embrace urban food production and as city authorities seek to encourage and facilitate farming activities, it is clear that regulatory structures which allow it to happen should be incorporated into urban planning legislation at (in the Australian context) state government level. If cities want to encourage urban agriculture, planning legislation needs to be part of the broader legal framework for enabling it to germinate and thrive.

This paper explores the emergence of two new types of urban agriculture: first, the multi-functional, small-scale urban farming operation, situated conceptually between a community garden and a full-scale commercial agricultural enterprise, and located spatially in the midst of built-up urban form; and second, the intensive, high tech export-oriented model exemplified by the Aerotropolis Agribusiness Precinct.

The study aims to explore institutional adaptation for sustainable water resources management at the local level in the context of increasing climate-related challenges in Zimbabwe using the case of a semi-arid area in the mid-Zambezi Valley, north of the country.

Inspired by the critical institutionalism approach, the study uses qualitative methods (i.e. key informant interviews, semi-structured interviews, community workshops and documentary review) to understand the role of different formal and informal water-related institutions vis-à-vis responding to climate-related challenges in the case study area, and how the identified institutions can improve their efforts in the context of national water and environmental policy and regulation frameworks. Thematic analysis was used for data analysis.

The study found that climatic challenges in the case study area, as in most of rural Africa, have raised the stakes in local water management with respect to regulating access to and balancing competing interests in, and demands for, water. It ultimately argues for the embracing of complexity thinking and flexibility in local water management as well as clear coordination of institutions across scales in the face of increasing climate-related challenges.

The study adds to case studies and evidence-based analyses focused on institutional alternatives for climate adaptation vis-à-vis water resources management in water-stressed rural African communities.

This study aims to explore possible ways to promote uptake and integration of climate-smart agriculture (CSA)-Technologies, Innovations and Management Practices (TIMPS) into policy and practice in Nigeria through the development of actionable roadmaps to facilitate the process.

Two hundred and fifty-two stakeholders for the policy discourse and survey were purposively drawn from both government and private agencies, NGOs and community-based associations from the six geo-political zones of the country. Data collection was done using a mixed method comprising questionnaire administration, in-depth interviews and panel discussion. Data collected was summarised using descriptive statistics.

The major findings were lack of existing policies on CSA, lack of farmers’ awareness of CSA-TIMPs, neglect of extension programmes that can help to enlighten farmers on the importance of CSA and insufficient extension personnel to cater for farmers’ needs. Challenges to CSA-TIMPs uptake in Nigeria were: insufficient funding and support by government in programme planning and implementation, policy inconsistencies and poor farmers’ attitude and resistance to change.

This research will facilitate CSA uptake and integration through the provision of data for informed decision and action by the responsible agencies.

Suggested actionable roadmaps across the zones were robust awareness campaign and advocacy on uptake of CSA-TIMPs through e-extension, community TV/radio in local dialects; revitalisation of policy programmes such as monthly meetings should be reintroduced and creation of CSA Departments/Stations in each state; increased budget allocation to a minimum of 10% for agriculture, revitalisation of Researchers-Extension Agents-Farmers Linkage, employment of qualified extension agents and retraining of extension agents.
