AbstractSome influential variables that are import to farmers in Northern Bangladesh regarding land use decisions for farmlands, where such options are possible, were explored in this study. A multi-stage sampling procedure was followed to select the study area and the sampling unit. We selected four sub-districts in Mymensingh district, a suitable area in Bangladesh for freshwater fish farming: Mucktagachha, Trishal, Phulpur, and Bhaluka. The PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluations) method was used to remove the problem of simultaneously selecting all criteria for land use decision-making, hence revealing the effects of some important variables on decisions on land use made by farmers. PROMETHEE model gave equal preference to rice over fish farming after all criteria were considered simultaneously. Although fish farming total return was about 6 times higher than rice farming, farmers were more interested in rice farming because of three major influential criteria: it requires less labor, operates at lower costs, and has zero conversion cost associated with rice farming.

The present research aims at investigating the economic performance of mixed ricefish farming in south-west region of Bangladesh. In order to carry out the research objective descriptive statistics, profit function, Cobb-Douglas form of multiple linear regression model and t-test approaches have been applied. The study area has been selected using multi-stage sampling technique and convenient sampling method has been utilized to select the sample. In-depth interview technique has been employed to collect primary data by using pretested questionnaire from the samples. Results from descriptive statistics show that the average annual return on mixed rice-fish farming is BDT 56326.45 more than mono rice farming as well as production efficiency of mixed rice-fish farming is also found higher than mono rice farming. Besides, mixed rice-fish farming experiences increasing return to scale, whereas, mono rice farming undergoes decreasing return to scale. Moreover, test of hypothesis provides statistical evidence that mixed rice-fish farming is more profitable than mono rice farming in the study area.Res. Agric., Livest.

Land Use Decisions

Purpose – Land use change in the Alpine Regions is dominated by two main factors: a process of re-naturalization and a process of expansion for settlements with the relevant occupation of low-valley areas. The purpose of this paper is to present an overview of land take measures in the Lombardy Alpine context and the recent proposals of spatial planning instruments for land resource management. New solutions to limit soil sealing have to be confronted with qualitative proposals at local scale. Design/methodology/approach – The paper collects different research outputs regarding land take in the Italian Alpine context and carried out by GIS software and tries to show the new methodologies available for limiting and mitigating soil sealing, in accordance with DIAMONT aims. Findings – The paper argues that the data are now available to analyze the problem and new operative methods have to be settled in the recent context of European Union (Soil Sealing Guidelines) to support decision making in planning, suggesting land use allocation and possible ecological compensation. Research limitations/implications – The new qualitative decision models have to be assessed for a better ecological integration in supporting land use decisions. Practical implications – An evaluation of land take at local scale caused by land use changes is a good support in the decision-making process of planning. Originality/value – In this paper a method based on a local scale is reported, which can be used for the specific assessment of land take in order to support land-use decisions.

The Impact

<p>Increasing global populations are placing increasing pressure on our natural systems, reducing their capacity to produce the ecosystem services that we rely upon for human wellbeing (World Bank, 2004).   Clarifying the implications of land-use decisions across the range of ecosystem services is fundamental to understanding the trade-offs inherent in land-use options. LUCI (the Land Utilization and Capability Indicator) is an emergent Geographic Information Systems (GIS) based framework developed to enable the mapping of several ecosystem services in a spatially explicit manner. This process enables a clearer understanding of the inter-dependencies between ecosystems and potential implications and trade-offs of management interventions across a range of services.   There is however, limited understanding of the impact, utility and credibility of such tools for land-use decision-makers, or of how they perceive the information conveyed. This Thesis considered the impact that presenting information on land-use trade-offs through LUCI had on land-owners at the farm scale.   This research supports previous findings that information alone does not drive behaviour (or decision-making) (Kollmuss, 2002, Fisk, 2011; Kennedy, 2010; Mackenzie-Mohr, 2000; Stern, 2000). Similarly, perceived credibility was not the main driver of decision-making nor is it necessarily rationally based. However without it, voluntary adoption of a new technology or tool is unlikely. Therefore, in seeking to diffuse tools, such as LUCI within a community, process design should take into account the social structures and the characteristics of targeted individuals within that community. The influence of temporal and context specific factors on decision-making provides both barriers and opportunities for technology diffusion.  The research findings propose that when integrating new tools and technologies within communities, consideration is given to using a suite of tools, mechanisms and theories in concert such as Community-Based Social Marketing (Mackenzie-Mohr, 2011) and Diffusion Theory (Rogers, 2003) to facilitate improved diffusion and uptake by communities.</p>

Modelling System

The science of ecosystem service (ES) mapping has become increasingly sophisticated over the past 20 years, and examples of successfully integrating ES into management decisions at national and sub-national scales have begun to emerge. However, increasing model sophistication and accuracy—and therefore complexity—may trade-off with ease of use and applicability to real-world decision-making contexts, so it is vital to incorporate the lessons learned from implementation efforts into new model development. Using successful implementation efforts for guidance, we developed an integrated ES modelling system to quantify several ecosystem services: forest timber production and carbon storage, water purification, pollination, and biodiversity. The system is designed to facilitate uptake of ES information into land-use decisions through three principal considerations: (1) using relatively straightforward models that can be readily deployed and interpreted without specialized expertise; (2) using an agent-based modelling framework to enable the incorporation of human decision-making directly within the model; and (3) integration among all ES models to simultaneously demonstrate the effects of a single land-use decision on multiple ES. We present an implementation of the model for a major watershed in Alberta, Canada, and highlight the system’s capabilities to assess a suite of ES under future management decisions, including forestry activities under two alternative timber harvest strategies, and through a scenario modelling analysis exploring different intensities of hypothetical agricultural expansion. By using a modular approach, the modelling system can be readily expanded to evaluate additional ecosystem services or management questions of interest in order to guide land-use decisions to achieve socioeconomic and environmental objectives.

Restoration Practices

Restoring interlocking forest-agricultural landscapes—forest-agricscapes—to sustainably supply ecosystem services for socio-ecological well-being is one of Malawi’s priorities. Engaging local farmers is crucial in implementing restoration schemes. While farmers’ land-use decisions shape land-use/cover and changes (LUCC) and ecological conditions, why and how they decide to embrace restoration activities is poorly understood and neglected in forest-agricscape restoration. We analyze the nature of farmers’ restoration decisions, both individually and collectively, in Central Malawi using a mixed-method analysis. We characterize, qualitatively and quantitatively, the underlying contextual rationales, motives, benefits, and incentives. Identified decision-making rules reflect diverse and nuanced goal frames of relative importance that are featured in various combinations. We categorize the decision-making rules as: problem-solving oriented, resource/material-constrained, benefits-oriented, incentive-based, peers/leaders-influenced, knowledge/skill-dependent, altruistic-oriented, rules/norms-constrained, economic capacity-dependent, awareness-dependent, and risk averse-oriented. We link them with the corresponding vegetation- and non-vegetation-based restoration practices to depict the overall decision-making processes. Findings advance the representation of farmers’ decision rules and behavioral responses in computational agent-based modeling (ABM), through the decomposition of empirical data. The approach used can inform other modeling works attempting to better capture social actors’ decision rules. Such LUCC-ABMs are valuable for exploring spatially explicit outcomes of restoration investments by modeling such decision-making processes and policy scenarios.

Human Systems

Individuals who influence decisions regarding the use of land, operate within a complex environment comprised of interacting elements that include both natural systems and human institutions. Individually, the elements of the natural and human systems that influence land-use decisions may be very complex. Within natural systems, dynamic processes, such as the hydrological cycle, and the distribution of biophysical resources, such as soil fertility, influence land-use decision making. Elements of an individual’s institutional environment can also influence the options and incentives that are available to an individual, and thus the land-use decisions that thhey make. Understanding the nature of these complex processes and interactions is a nontrivial task. However, agent-based simulation offers researchers a tool to better understand the nature of these complex systems. The recent development of computer simulation technologies by social scientists has provided a tool for not only predicting social phenomena, but also for better understanding the nature of these human systems. Replicative validity is not the goal of many social simulation efforts. Instead, researchers have focused on developing relatively simple simulations as tools for understanding the properties of social systems and the way in which interactions between actors at the local level results in the emergence of behaviors or phenomena at the global level. In this role, simulation becomes a tool for evaluating assumptions and exercising theories of action. Many of the techniques applied to social simulation can be traced back to earlier developments in the physical or natural sciences. For example, computer simulation has a relatively long history in the natural sciences in applications related to fisheries, forest environments, and watersheds. But recent advances in computer hardware and software technologies have made these technologies accessible to social scientists. Recently, we have seen simulation efforts that have included models of not only the natural system in question, but also the human system with which it interacts. In fields such as anthropology and resource management , human systems simulations are being developed which directly address the actions of human individuals or groups as they interact with a natural system. This approach to simulation is pursued in this chapter.

The study analysed constraints to women involvement in fish farming and processing in Anambra State Nigeria. Multi-stage sampling  procedure was employed in selecting 90 women fish farmers. Data were analysed using percentage and mean as well as ordinary least  square regression. The study revealed that the women mostly used concrete pond (65.6%), the majority (70.0%) have between 1 and 3 ponds. Catfish was mainly cultured by the women (86.7%). The foremost constraints faced by the women in fish farming were  inadequate capital ( = 3.31), inadequate land for expansion ( = 3.27), and high cost of fish pond establishment ( = 3.23). The coefficient of inadequate capital (-1.503) was significant at 1%, while the coefficients of inadequate land for expansion (-1.286), pre-occupation with other household chores (1.245), dominance by spouses (1.601) and high cost of fish pond establishment (- 1.768) were significant at 5% significant level. Providing low interest loans to active and registered women fish farmers, revisiting and amending the 1999 land reform, encouraging women to form formidable cooperative societies, among others were recommended by the study.

Agroforestry remained a profitable venture across the globe if managed well spatially and temporarily. Farmlands are viable option to practice agroforestry in Pakistan for sustaining farmers’ livelihoods as well as to provide products and services for ever increasing population. This study focusses on how agroforestry is being perceived as profitable enterprise by the farmers in Multan, Punjab Pakistan. Rural areas of Multan were selected for this study and 200 farmers were selected randomly from 10 villages across 02 union councils using multi-stage sampling procedure. The results revealed that agroforestry remained the prime land use system as reported by the farmers (99%) belonging to agropastoral and agroforestry practice. Moreover, agroforestry perceived as high-income system providing variety of product (increased crop and fodder production, variety of products and income) and services (Carbon sequestration, climate amelioration, soil conservation). The study concluded the need for public-private partnership for the promotion of agroforestry in the region.
