Infrastructure development and ProRLK (deforested Land Rehabilitation Project) a Government of Indonesia collaboration prpject with The German Technical Coorperation Agency (GTZ) in 1992, has shifted the pattern of shifting cultivation to rubber farming in Nagari Silayang. Households engaged in shifting cultivation for food needs, stopped this entrenched practice, and focused on rubber plantations for food needs and financial means. But in recent years, the practice of shifting cultivation has been rife in Nagari Silayang. This phenomenon refutes the theory of agricultural transformastion in many previous studies, which concluded that shifting agricultural patterns lead to patterns that increasingly leave shifting cultivation. The purpose of this study, is to find the factors that cause farm households in Nagari Silayang to return to shifting cultivation, and find ways or strategies to stop forest clearing for swidden land. The research method used is descriptive qualitative and quantitative. Data collection uses observation, key informant interviews and household surveys. the results showed that the revival of shifting cultivation in Nagari Silayang was caused by the decline in global rubber prices, maintaining food security, and efforts to increase household income. This will have an impact on biodiversity damage and even natural disasters, because old forests are converted to agricultural land. This leads to negative impacts on biodiversity and can result in natural disasters, as old forests are converted to agricultural land.

Abstract. Water infrastructure development is crucial for driving economic growth in the developing countries of the Mekong. Yet it may also alter existing hydrological and flood conditions, with serious implications for water management, agricultural production and ecosystem services, especially in the floodplain regions. Our current understanding of the hydrological and flood pattern changes associated with infrastructural development still contain several knowledge gaps, such as the consideration of overlooked prospective drivers, and the interactions between multiple drivers. This research attempts to conduct a cumulative impact assessment of flood changes in the Cambodian part of the Mekong floodplains. The developmental activity of six central sectors (hydropower, irrigation, navigation, flood protection, agricultural land use and water use) as well as climate change were considered in our modelling analysis. Our results show that the monthly, sub-seasonal, and seasonal hydrological regimes will be subject to substantial alterations under the 2020 planned development scenario, and even larger alterations under the 2040 planned development scenario. The degree of hydrological alteration under the 2040 planned development is somewhat counteracted by the effect of climate change, as well as the removal of mainstream dams in the Lower Mekong Basin and hydropower mitigation investments. The likely impact of decreasing water discharge in the early wet season (up to −34 %) will pose a critical challenge to rice production, whereas the likely increase in water discharge in the mid-dry season (up to +54 %) indicates improved water availability for coping with drought stresses and sustaining environmental flow. At the same time, these changes would have drastic impacts on total flood extent, which is projected to decline up to −18 %, having potentially negative impacts on floodplain productivity whilst at the same time reducing the flood risk to the area. Our findings urge the timely establishment of adaptation and mitigation strategies to manage such future environmental alterations in a sustainable manner.

Chili (Capsicum annum L.) often experience the highest price fluctuations in Indonesia. This is caused by the production that is often disrupted in certain months, especially in the months in the rainy season due to flowers and fruits that fall before the harvest. Since agricultural land has changed its function for infrastructure development, marginal land (Ultisol) is used. The ultisol problem is: high acidity, low organic matter content, nutrient deficiency important for plants (eg N, P, Ca, Mg and Mo) and high solubility of Al, Fe and Mn. The provision of organic materials such as manure and marine mud will overcome the problem of acid-rich mineral soil and play an important role in improving, increased and maintaining sustainable land productivity. Research results for chili flower significantly. the highest number of flowers found in the treatment of L0P3, L1P2, L1P3 and L2P3 that is > 60 flower/plant. There was a single factor effect for the amount of fruit, mostly found in L3 treatment (600 ton/ha marine mud) that is 22.36 fruit/plant. The treatment of manure significantly influenced the formation of the most fruit set in the treatment of P0 and P2 (without manure and manure 20 ton/ha) that is 77.60% and 70.,45%. Keywords: Ultisol, Marine mud, Manure, Flowers and Fruit sets   ABSTRAK Tanaman cabai besar (Capsicum annum L.) sering mengalami fluktuasi harga paling tinggi di Indonesia. Hal tersebut disebabkan oleh produksi yang sering terganggu pada bulan tertentu terutama pada bulan-bulan di musim penghujan dikarenakan bunga dan buah yang rontok sebelum panen. Karena lahan pertanian banyak beralih fungsinya untuk pembangunan infrastuktur, maka digunakan lahan marginal (Ultisol). Masalah ultisol ialah: kemasaman tinggi, kadar bahan organik yang rendah, kekurangan unsur hara penting bagi tanaman (contoh: N, P, Ca, Mg dan Mo) serta tingginya kelarutan Al, Fe dan Mn. Pemberian bahan organik seperti pupuk kandang dan Lumpur laut akan mengatasi persoalan tanah mineral masam berkadar Al tinggi dan berperan penting dalam memperbaiki, meningkatkan serta mempertahankan produktifitas lahan secara berkelanjutan Hasil Penelitian untuk jumlah bunga cabai berpengaruh signifikan. jumlah bunga terbanyak terdapat pada perlakuan L0P3, L1P2, L1P3 dan L2P3 yaitu > 60 bunga/tanaman. Terjadi pengaruh faktor tunggal untuk jumlah buah, terbanyak terdapat pada perlakuan L3 ( 600 ton/ha lumpur laut) yaitu 22,36 buah/tanaman.

AbstractThe Zambian government has introduced the farm block development programme (FBDP) to facilitate agricultural land and rural development and encourage private sector investment. This study assessed whether the FBDP achieves these goals. Key obstacles and possible opportunities were also identified and, where appropriate, specific corrective actions were recommended. Qualitative data were collected through semi-structured interviews conducted in Lusaka with various stakeholders of the FBDP. The FBDP is designed to facilitate agricultural land development and encourage private sector investment. However, the programme falls far short in terms of implementation, amidst policy uncertainty and lack of support. This is evident by the insecurity of land tenure which negatively affects small- and medium-scale producers’ access to financing, lack of infrastructure development of these farm blocks, and constraints in the agricultural sector such as low labour productivity and poor access to service expertise. It is recommended that innovative policy interventions should be created to support agricultural development. This can be achieved by following a multistakeholder approach through involving private, public and non-profit sectors such as non-governmental organisations (NGOs) and donors.

Unplanned Development

Urban sprawling and unplanned infrastructure development are devouring productive land. Bangladesh is basically an agro based economy. In our country, about 1% of agricultural land in each year is transferred to another use. If this process continues all of our agricultural land would diminish within 100 years. This terrible situation is very crucial for an agro-based economy. In this paper, an attempt has been made to illustrate the necessity of introducing the Urban Promotion Control Area (UCA) in preparing physical development plan in Bangladesh to save agricultural land. This idea is well practiced in Japanese city planning. Unplanned development of physical infrastructure, especially development of unplanned road is the main cause of urban sprawling into the valuable agricultural land. The awful encroachment into the agricultural land also may cause haphazard urbanization. This type of land use regulation may protect the unpleasant encroachment into the UCA land. Public investment in UCA for urban infrastructure development could be strictly prohibited, so that unplanned development would be restricted.DOI: http://dx.doi.org/10.3329/jbip.v2i0.9570Journal of Bangladesh Institute of Planners Vol. 2, December 2009, pp. 98-106

The natural disasters of the earthquake, liquefaction, and tsunami that occurred on September 28,2018 in Palu, Sigi, and Donggala have caused damage and even loss of residence and property ofthe people in the region. Agricultural land which was a source of livelihood could not be reused.During the recovery phase in the aftermath of natural disasters, the government andhumanitarian agencies could rebuild facilities and infrastructure including the economy ofdisaster victims. Central Sulawesi Assessment Institute for Agricultural Technology (AIAT)participated in the socio-economic recovery of natural disaster victims in Sigi Regency through thedevelopment of superior BALITBANGTAN (KUB) chicken based on native households in temporaryshelters in Jono Oge Village, Sigi Regency. The purpose of this study was to determine thecontribution and motivation of Sigi disaster victims in raising KUB chickens based on households.The contribution of raising KUB chicken was calculated from the percentage of KUB chicken tototal household income while motivation was measured by the scoring method using a Likert scale.Based on the results of the assessment, it was concluded that the income of victims of naturaldisasters at the Jono Oge Village in Sigi Regency had contribution contribution of raising KUBchickens based on households was 8.08% categorized at <Rp1,500,000.00 and 4.21% categorize atRp1,500,000.00 - Rp2,500,000.00. The motivation of natural disaster victims for raising KUBchickens was on the ease of sales and maintenance.

This study was designed to identify the status of shifting (jhum) cultivation and its impact on environment in Rangamati district. A total 55 jhum cultivators were selected on the basis of purposive sampling technique from 5 upazillas of Rangamati district. Data were collected during the period October to December, 2009. The researcher collected information himself using direct and open questionnaire. The study revealed that most of the jhum cultivators were middle age (30-50 years), with illiterate (47.27%) and main occupation possessing jhum cultivation. The present status of agricultural land (hill/slope) of jhumia family in the studied area, about 60% of the respondents have only 1-2 acres of land for jhum cultivation and 25% of the respondents have 2.1-3 acres of land. The use of agro-chemical remains limited in the CHT. This is mainly because of financial constraints, lack of market access, and low requirement of chemical for traditional jhum cultivation. The maximum percentage of irrigation (74.55%) was mainly depended on rainfed in jhum cultivation. On the other hand about 45.55% respondents were responded that their income status were medium through shifting cultivation, 30.90% were responded high. Similarly in the study area it was found that a majority (45.45%) portion of respondents were responded that labour utilization in shifting cultivation was medium. This study also found that the environment was degraded gradually day by day. The maximum respondents (94.55%) had given opinion that deforestation was the major environmental problem created by shifting cultivation, 74.55% respondents had given opinion that shifting cultivation accelerated loss of top soil and 60.00% respondents had given opinion that lost of wild animals was occurring due to shifting cultivation. Biodiversity also degraded mostly. Excluding shifting cultivation there were many reasons of environmental degradation in the study area. Population growth is considered by 90% of the respondents as a major factor causing severe degradation of environment. Indiscriminate forest fire was responsible for environmental degradation. In addition cutting of hill, collection of soil, and extraction of stone, river erosion and land slide as responsible for degradation of environment. The study recommended that new methods must be developed, applied, and tested for sustainable management of jhum cultivation and environmental protection.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14840 J.

Pakistan is exposed to various natural calamities due to its geophysical condition and climatic changes. In addition, man-made disasters also pose a threat to human lives and properties which includes industrial and transport disasters including oil spills, civil unrest, wars and conflicts. Although it is not possible to stop or prevent natural disasters, but the negative impacts of natural disasters can be minimized through human efforts. The government of Pakistan has adopted participatory approach as part of its policy for disaster management. This research paper is based on the analysis of secondary data for reviewing the existing policies with emphasis on disaster risk reduction in pre and post disaster period. The paper concludes that participation of target community is indispensable for disaster risk reduction on sustainable basis. The article suggests that community should be meaningfully involved in disaster risk reduction efforts at the local level. In this connection the role of social workers is indispensable for disaster risk reduction on sustainable basis.

Over the years, many studies have documented how the negative impacts of infrastructure investments are disproportionately borne by women, the poor and racial minorities. In this paper, we focus on the ways that unequal gender dynamics are a key feature of the production of infrastructure, a topic that has received far less attention. In particular, we show how masculinity is deeply embedded in the organizational structures, employment practices, symbolic narratives and systems of power that create the vast arrays of infrastructure globally. We discuss the implications of a masculinist network of infrastructure development, and point to directions for future research.

&lt;p&gt;Climate change will likely exacerbate droughts, increase regional water demands and affect agricultural yields. In addition, projected population growth combined with lack of &amp;#160;&amp;#8216;good&amp;#8217; governance is likely to enhance the negative impacts of droughts and crop failure in the future as agriculture increasingly expands onto marginal lands. There is a global concern about these trends, because crop failure, droughts, increasing pressure on suitable agricultural land and rangeland for livestock, and changes and quality of governance can also increase the risk of conflict and (organized) violence.&lt;/p&gt;&lt;p&gt;In this presentation we explore the strength and impact of the climate-conflict trap., We use historical drought simulations and future drought projections to study the link between conflict and drought. Conflict data are taken from the Uppsala Conflict Data Program and combined with hydrological simulations from the global hydrological model PCR-GLOBWB.&lt;/p&gt;&lt;p&gt;The results show that drought occurrence is expected to increase under all climate scenarios, with stronger impacts for the higher emission scenarios. &amp;#160;On the other hand, at the global scale conflicts are likely to reduce as increased economic wealth compensates for the increased climate vulnerability.&lt;/p&gt;&lt;p&gt;This work helps us to better understand the interplay between the natural hydrological system and society. To better understand unsustainable and potentially devastating pathways for the coming decades, we have the greater aim to start unravelling the complex dynamics between changes in drought, society and risk of conflicts.&lt;/p&gt;

AbstractThe ever increasing pressure for infra-structural development in the UK heightens the conflict between the different land use demands placed on an area. This is reflected in the need for planning authorities to assess the relative suitability of potential land uses. Such assessments are important in guiding urban development away from good quality agricultural land. It is manifest that such planning decisions should be made on the basis of a comprehensive review of all relevant factors, and in particular, this includes the pedological soil conditions with their controlling influence on the ability of the land to support different land uses.Past pedological studies have tended to concentrate on the evaluation of land suitability for agricultural uses. However, such studies are also of value when assessing the suitability of other potential uses including, forestry, recreational uses, natural resources or general infrastructure development.In site investigations for infrastructure or resource development pedological studies have a role to play both at the feasibility and detailed investigation stages. During a feasibility study, particularly when used in conjunction with a programme of geotechnical mapping, a pedological approach to the examination of point samples can be an important aid in the determination of the areal extent of engineering soil units. In detailed investigations pedological assessments during pitting operations can determine such items as the depth of topsoil to be removed and stored during stripping, if a profile has developed through in-situ weathering of bedrock or a derived superifical cover and will assist in the identification of poor drainage areasIn this paper examples are presented of soil surveys used to assess the suitability of areas for recreational use, urban development and forestry. Also, by comparing the approaches to soil description contained within BS 5930, Code of Practice for Site Investigations (British Standards Institution 1981), and the Soil Survey Field Handbook (Hodgson 1974), some recommendations are made for adopting pedological description techniques in geotechnical site investigations.
