Farmer Behaviour

Projections of global demand for rice is expected to increase at the rate of 1.5% per year (or 48.5% by 2050). The crop production increase must be done sustainably from existing farming land due to the reduction in availability and quantity of resources. Having more local studies enhances our understanding of different farmer characteristics and behaviour, socio-economic conditions and other essential constraints faced by individual farmers. This is needed for fine-tuning farming systems research which will lead to a profitable and sustainable increase in farming production. This study aims to understand and assess the lowland rice-based farming systems in Northwest Cambodia, and examine options to enhance rice production, profitability and sustainability. Farmer surveys were conducted using the CommCare Mobile Acquired Data (MAD) system and 524 farmers were interviewed. The survey identified farmers’ key constraints on crop production, their knowledge gaps and limitations and the rice yield gaps which exist in Northwest Cambodia. Agricultural research and development priorities should be focused on crop establishment method, sowing window, weed and nutrient management strategies, overall soil health improvement, crop rotations and cover crops that can improve cropping systems, profitability and sustainability. An increase in understanding of farmer behaviour, adoption constraints and barriers, together with other essential interaction at the local level is also crucial when aiming to promote improved farming innovations.

Farming Systems Research

Summary. Farming systems research was introduced into many international and national agricultural research institutes in lower income countries in the 1970s and 1980s with the purpose of improving the relevance of research for small-scale farmers. This review outlines the origin, context, goals, principles and process of farming systems research in these countries, and aims to enable agricultural professionals to assess the relevance and value of farming systems research to their work in particular situations in Australia and overseas. The key elements of farming systems research include a holistic approach, orientation towards the needs of defined target groups, high levels of farmer participation and hence co-learning by farmers and specialists. There is guidance by facilitators, continuous evaluation and linkage to policy makers. The goal of farming systems research is to improve the well-being of farmers through development of farming systems. It involves application of methods from various disciplines, first to define the constraints and opportunities for development and then to overcome these in a research process involving farmers, with specialists and policy makers. A generalised farming systems research procedure and various research activities are described. Initially in lower income countries, a fairly standard farming systems research procedure was used, but farming systems research has evolved to encompass a range of activities commonly regarded as the realm of agricultural extension or rural development. Basic science, applied science and farming systems research are compared in terms of the roles and relationships of the people involved in the research process. The implications of selecting farming systems research as a model for rural research and development are discussed. Achieving adequate levels of farmer participation can be a major issue in farming systems research so it is important that the principal notions of participation are understood. Success of farming systems research in Australia will depend on developing innovative ways of achieving high levels of participation. Current trends in the philosophy, practice and funding of agricultural research and extension in Australia make it timely to consider the wider adoption of farming systems research principles and practices. Farming systems research could provide a valuable philosophical and practical basis for the trend towards greater participation by researchers with end-users and extension practitioners in agricultural development programs. However, it seems unwise to adhere strictly to any one particular model of research and development from other places: farming systems research concepts are being combined successfully with those from other models, such as systems learning and computer modelling, to suit the needs of particular situations. Implications of a wider adoption of farming systems research in Australia for agricultural research and development organisations and professional bodies include, the establishment of multidisciplinary teams with shared goals, and the sourcing of funding for periods long enough to achieve outcomes. There is also a need for training in systems concepts and facilitation, for reputable channels of publication of the results of farming systems research and for greater recognition of participatory activities as valid forms of agricultural research.

<p><strong>Abstrak</strong>. Wilayah Nusa Tenggara mempunyai lahan kering beriklim kering seluas 4,9 juta ha dengan curah hujan &lt;2.000 mm/tahun dan bulan kering 5-10 bulan, bersolum tanah dangkal dan berbatu. Sebagian lahan tersebut sudah dimanfaatkan menjadi lahan pertanian terutama jagung, akibatnya produktivitas tanaman jagung rendah dibandingkan potensi genetiknya, yaitu sekitar 2,5 ton/ha di NTT dan 5,3 ton/ha di NTB dibanding dengan potensi genetiknya 9 ton/ha. Sejak tahun 2010-2015, Badan Penelitian dan Pengembangan Pertanian telah mengembangkan inovasi teknologi pengelolaan lahan kering beriklim kering dan berbatu di beberapa kabupaten di NTT dan NTB, meliputi penyediaan sumberdaya air (dam parit, embung, tampung renteng mini, sumur dangkal), pengenalan varietas unggul baru dan budidaya tanaman pangan. Pembelajaran yang diperoleh menunjukkan bahwa penyediaan air menjadi titik ungkit untuk meningkatkan indeks pertanaman dan produktivitas tanaman. Inovasi teknologi yang dibutuhkan petani adalah, mudah diterapkan, biaya murah, dan efisien tenaga kerja mendorong berlanjutnya teknologi tersebut meskipun progam tersebut telah selesai. Pada tahun 2014-2018 telah dilaksanakan kegiatan pertanian konservasi melalui dana hibah barang dan jasa yang dikelola FAO. Prinsip dasar pertanian konservasi terdiri atas 3 pilar, yaitu olah tanah terbatas berupa lubang olah permanen, penutupan permukaan tanah, rotasi/tumpangsari. Lubang tanam tersebut diberi pupuk kandang atau kompos, dan ditanami jagung pada 4 penjuru lubang, dan ditumpangsarikan dengan berbagai kacang-kacangan atau tanaman merambat seperti labu kuning yang berfungsi sebagai penutup tanah dan penghasilan tambahan dari kacang-kacangan berumur pendek. Berdasarkan hasil analisis tanah sebelum dan sesudah implementasi pertanian konservasi menunjukkan bahwa pertanian konservasi dapat meningkatkan kesuburan tanah, retensi air dan meningkatkan produksi tanaman jagung.</p><p> </p><p><strong>Abstract</strong>. The Nusa Tenggara region has upland area with dry climate of 4.9 million ha, less than 2,000 mm annual rainfall, 5-10 dry months, shallow and rocky soils. Some of the land has been used for agricultural development, especially corn, resulting in low corn productivity of around 2.5 tons / ha in NTT and 5.3 tons / ha in NTB as compared to it genetic potential 9 tons /ha. Since 2010-2015, Indonesian Agency of Agricultural Research and Development has developed innovation of soil management technology for upland with dry climates and and rocky soils in several districts in NTT and NTB. The innovation includes the provision of water resources (dam trenches, reservoirs, mini catchments, and shallow wells), introduction of new high yielding varieties and cultivation crops. The lessons learned show that water supply is the initial point to increase cropping index and crop productivity. Technological innovations needed by farmers are easy to implement, low cost, and labor efficient thereby encourage the continuation of the technology even though the program has been completed. In 2014-2018, conservation agriculture activities were carried out through grants of goods and services managed by Food Agriculture Organization (FAO). The basic principle of conservation agriculture consists of 3 pillars, namely limited tillage in the form of permanent planting holes, cover crops, rotation / intercropping. The planting hole is given manure or compost, and planted with corn in 4 corners, and intercropped with various nuts or vines such as pumpkin that serves as a soil cover and additional income from short-lived beans. Based on the results of soil analysis before and after the implementation of conservation agriculture, it shows that conservation agriculture can increase soil fertility, water retention and increase corn crop production.</p>

Developing new and improved grazing systems for crop–livestock farms where crop production is the major driver of farm management decisions presents a unique research and development challenge. In southern Australia, a substantial proportion of animal production from grazing comes from regions and farms where cropping is the major enterprise. In this paper, we describe a multi-disciplinary farming-systems research approach (EverCrop) aimed at improving farm profitability, risk management and environmental impacts through the development and integration of new grazing options with an emphasis on perennial species. It has been used to analyse and target new opportunities for farmers to benefit from perennial species across dry Mediterranean-type and temperate regions of southern Australia. It integrates field experimentation, on-farm trialling, farmer participatory research, soil–plant–climate biophysical modelling, whole-farm bioeconomic analysis and evaluations of adoptability. Multi-functional roles for summer-active grasses with winter cropping, integration of forage shrubs and establishment of new mixes of perennial grasses in crop rotations to improve farming system performance are identified, along with an analysis of factors likely to affect rate of uptake by farmers.

SUMMARYResearch institutes in Africa have had limited success in producing new technologies appropriate to the needs of small farmers because of an inadequate understanding of small farmers' goals and resource limitations and over-reliance on the transfer of technologies from other regions. Farming systems research (FSR) is an effective way of improving the focus of scientists on the problems farmers face. Vertically segmented thematic research programmes make institutionalization of FSR difficult within multi-commodity research centres, particularly the International Agricultural Research Centres. The Farming Systems Research Group has proved effective at overcoming such difficulties at the International Institute of Tropical Agriculture. Its organization, operation and effects on the performance of the research programmes are described.

Thiessen Martens, J. R., Entz, M. H. and Wonneck, M. D. 2015. Review: Redesigning Canadian prairie cropping systems for profitability, sustainability, and resilience. Can. J. Plant Sci. 95: 1049–1072. Redesign of agricultural systems according to ecological principles has been proposed for the development of sustainable systems. We review a wide variety of ecologically based crop production practices, including crop varieties and genetic diversity, crop selection and rotation, cover crops, annual polyculture, perennial forages, perennial grains, agroforestry systems, reducing tillage, use of animal manures and green manures, soil biological fertility, organic production systems, integrated crop–livestock systems, and purposeful design of farm landscapes (farmscaping), and discuss their potential role in enhancing the profitability, environmental sustainability, and resilience of Canadian prairie cropping systems. Farming systems that most closely mimic natural systems through appropriate integration of diverse components, within a context of supportive social and economic structures, appear to offer the greatest potential benefits, while creating a framework in which to place all other farming practices. Our understanding of ecological relationships within agricultural systems is currently lacking, and a major shift in research, education, and policy will be required to purposefully and proactively redesign Canadian prairie agricultural systems for long-term sustainability.
