The advantages of urban and peri-urban agriculture in West African cities, namely its contribution to food production, income generation and resorbing unemployment are well reported. In the peri-urban areas, cropping systems and practices are various and may affect differently soil properties. Those systems and practices may be driven by farms socio-economic conditions. Here we conducted a study in 133 peri-urban farms located at the vicinity of the city of Ouagadougou. Farmers were questioned on their cropping practices and soil samples were taken and analyzed for their total organic C, available P and K contents. Principal component analysis allowed to study the variability of the farms considering cropping systems, the cropping practices and the farms socio-economic conditions. We found that in the studied cropping systems up to 60% of the farms variability was explained. Monoculture led to low soil organic carbon while polyculture led to low soil available K. The studied socio-economic conditions of the farms explained up to 60% of the variability in cropping practices.

AbstractAt the present time, urban agriculture—that is, the growing of food crops in backyard gardens, unused city spaces and peripheral zones—is an economically viable alternative for many African migrants. Although previously ‘invisible’ to most developers and economists, urban farming is now recognised as playing a crucial subsistence role in the household economies of lower-income people living in major West African cities. But the practice does more than feed the urban poor. Using the example of Ziguinchor in Casamance, Senegal, it is argued that growing crops in peri-urban and intra-urban zones, on otherwise neglected or half-built-up land, also protects and enriches the city environment while increasing the primary productivity of the inhabitants. Directly, or in more subtle ways, the practice strengthens bonds of friendship, and promotes inter-ethnic co-operation while at the same time helping to maintain biological complexity in interesting and previously unexplored ways. City farming may provide a context through which the urban poor can relate to debates about biodiversity.

The dimension of the slums is presumed as something that is deteriorating urban areas that is densely populated and contains dilapidated housing, often in multiple occupations, poverty, social disadvantage and other forms of physical and social deprivation. Sprawl is a universal occurrence knowledgeable by inexpensively highly developed fine mounting nations. Hurried sprawl appropriate to “pull factor” or the livelihood occasion fashioned in the city and “push factor” owed to the be deficient in of the equivalent in rustic regions and together with ecological dilapidation, has fascinated settlers not barely as of the rustic state but in addition commencing supplementary fractions of the state. Expansion of mechanization roughly in capital of Tamil Nadu, in deprivation condition in the rustic locale, too little drizzle in the rustic part, castism, hastily and enormous edifice creation doings and approximately the city and in sequence expertise commons, has specified surety for accomplished, inexperienced, semi-skilled employments are existing to the justified citizens. In the present study main aims are income and expenditure activities of the Porur slum areas in Chennai city

Rice-based cropping systems are the foundation of food security in countries of Southeast Asia, but productivity of such systems has declined with deterioration in soil quality. These systems are different from other arable systems because rice is grown under submergence, and this may require a different set of key soil attributes for maintenances of quality and productivity. A minimum dataset was screened for assessing quality of soils belonging to three Soil Orders (Inceptisols, Entisols and Alfisols) by using statistical and mathematical models and 27 physical, chemical and biological attributes. Surface soils were collected from farmers’ fields under long-term cultivation of rice–potato–sesame cropping systems. Most of the attributes varied significantly among the Soil Orders used. Four or five key attributes were screened for each Soil Order through principal component and discriminate analysis, and these explained nearly 80% and 90% of the total variation in each Soil Order dataset. The attributes were dehydrogenase activity (DHA), available K, cation exchange capacity (CEC) and pHCa for Inceptisols; organic C, pHCa, bulk density, nitrogen mineralisation (Nmin) and β-glucosidase for Entisols; and DHA, very labile C, Nmin and microbial biomass C for Alfisols. Representation of the screened attributes was validated against the equivalent rice yield of the studied system. Among the selected key soil attributes, DHA and CEC for Inceptisols, organic C for Entisols, and Nmin and very labile C for Alfisols were most strongly correlated with system yield (R2 = 0.45, 0.77 and 0.78). Results also showed that biological and chemical attributes were most sensitive for indicating the differences in soil quality and have a strong influence on system yield, whereas soil physical attributes largely varied but did not predict system yield.

The geographical location of Bangladesh is gifted with enormous natural recourse: water, alluvial land,suitable climatic conditions for bio diversity and other natural assets. The capital, Dhaka, surroundedby rivers on four sides, was once a blue-green-built environment offering a healthy living atmosphere forits habitants. The city was dotted with huge and crisscrossed water bodies, a tolerable population density,and enough open spaces. Urban and peri-urban areas of the city complemented its food demand whichsubsequently maintained the environmental equilibrium. The modern concept of eco-urban-agriculture willdefinitely be beneficial in such a dense city which is rapidly losing its livability by insensitive urbanization.This paper will describe how a city could generate food, improve health, and utilize waste by furthering theestablished urban-agriculture concept. It aims to develop an understanding of this concept in Bangladesh,particularly in the dense urban fabric of Dhaka, by discussing the theoretical background of urban agricultureand practiced models of eco-urban-agriculture in urban settings around the world.

This research study was conducted on socio-economic conditions of families living in squatter’s settlement of Karachi. The urban population is booming with unprecedented growth due to heavy influx or migration of rural population to the cities especially in Karachi. The rural families are migrating to the city in a way to have better employment; improved lifestyles in urban societies. Migrators usually accommodated in squatters’ settlements of Karachi because of high residing cost in urban areas. The squatters’ settlements are located at outskirt of the city on government owned lands. However the provincial government has set up Sindh Katchi Abadi Authority (SKAA) department for upgrading or regularizing Katchi Abadis which are working under specific rules and regulations. In this study the role of SKAA also highlighted to analyze the working preferences of organization for the rehabilitation or betterment of squatter settlements. The research topic is chosen in order to investigate about the socio-economic issues of families living in squatters settlements. The data is collected from 200 respondents of squatters from squatters’ settlements which are situated in six different districts of Karachi. Data is collected by the self-prepared questionnaire which was prepared in a way to investigate socio-economic issues and problems of squatters’ families living in the settlements. This research found that whole sample of squatters is of migrators. These settlements are considered illegal and have no provision of basic necessities including drinking safe water; inadequate sanitation system; and low standard of housings.

The linden tree ( Tilia  spp.) is a popular tree for landscaping and urban environments in central and northwest European countries, and it is one of the most popular in cities in Poland. Ectomycorrhizal fungi form a symbiosis with many urban tree species and protect the host plant from heavy metals and against salinity. The aim of this study was to characterize the ECM fungal community of urban linden trees along the tree damage gradient. The study was performed on two homogeneous sites located in the centre of the city of Gdańsk, in northern Poland. The vitality assessment of urban linden trees was made according to Roloff’s classification. Tree damage classes were related to soil characteristics using principal component analysis. The five ectomycorrhizal fungal species were shared among all four tree damage classes, and  Cenococcum geophilum  was found to be the most abundant and frequent ectomycorrhizal fungal species in each class. Park soil had significantly lower pH and Na, Cl and Pb content than street soils. Our knowledge of ectomycorrhizal communities in urban areas is still limited, and these findings provide new insights into ectomycorrhizal distribution patterns in urban areas.

ABSTRACT Urban agriculture is currently carried out all over the world. The activity is characterized by its multifunctionality, contributing to food security, preservation of biodiversity, better use of urban spaces, and proper management of soil and water, in addition to contributing to increasing income and improving the quality of life of farmers who live in the cities. In the 1980s and 1990s, urban agriculture gained momentum on the international scene and, from 2005, in Brazil. Some successful experiences in the world (Detroit, Havana, and St. Petersburg) and in Brazil (Teresina, Sao Paulo, and Belo Horizonte) are briefly reported here. Then, we describe in more detail the case of the city of São Luís. The municipality is situated on an island and its rural spaces have characteristics of peri-urban areas. Agricultural production has low expression in municipal GDP (Gross Development Product). The main products are papaya, cassava, beans, bananas, coconut, and passion fruit and, among the vegetables, roselle, chives, coriander, and West Indian gherkin, traditional regional species of Maranhão cuisine. The activity has two primary groups of actors: producers and intermediaries, with 83 and 41% of them, respectively, living in rural areas. Almost all producers (92%) use their area, 79% use some sustainable fertilization practice, and 69% do not use pesticides. Production areas are small and producers need technical assistance. Transport and poor road conditions are the main challenges to bring products to the markets. The reality that came out from our study indicates the lack of public support to urban farmers in São Luís. On the contrary, successful experiences of urban agriculture have in common the convergence of public policies of urban planning, agriculture and supply, education, and health. Urban agriculture is dynamic and must be integrated into the urban ecosystem to make it possible to unveiling new perspectives on the countryside-city relationship.

The present research aims to understand the challenges faced by a Colombian city in the context of multidimensional risk scenarios, given the existing demographic and socio-economic conditions and local perspectives and perceptions regarding socio-environmental risks. The research was undertaken in the city of Barranquilla, northern Colombia. A survey was designed to analyze (1) the general socio-economic and vulnerability conditions of a communities’ sample, (2) information related to hazards and disaster risk in their neighbourhoods, and (3) information on actions to mitigate risk. Three hundred and ninety-one people were surveyed. Likert scale and Pearson's Chi-square test and descriptive, inferential statistical methods, regression models, and the Mann–Whitney U test were used to process the results. Respondents lived, in general, under precarious socio-economic conditions (such as low income or lack of infrastructure and others). Given socio-environmental constraints, the research revealed that hazards such as urban stream flooding and robbery were the most negatively associated with the respondent’s quality of life. Regarding the actions to avoid losses, 84% of respondents had not implemented any preventive action. Respondents also have low awareness of the need to implement risk prevention actions. Social risks and the configuration of anthropic hazards stand out as principal centres for concern.

Self-Reliance of Farmers in Managing Vegetable Farming in Denpasar City The development of urban agriculture has many challenges such as the difficulty ofobtaining production inputs, the difficulty of obtaining credit, the limited ofresources, the limited time, and the agricultural sector which is not a priority sector.Difficulties in farming in urban areas can be minimized with the self-sufficiency ofeach farmer. The purpose of the study was to investigate how the performance ofvegetable farming management and how the level of self-sufficiency of vegetablefarmers in Denpasar, as well as what factors influence the self-sufficiency ofvegetable farmers in the city of Denpasar in terms of capital, production andmarketing that are categorized in three classes of measurement i.e. less selfsufficiency,moderate self-sufficiency or full self-sufficiency analyzed by qualitativedescriptive method. The results showed that vegetables farming conducted byfarmers in the city of Denpasar was still classified as a traditional that rely on habits.The self-sufficiency seen from the aspects of capital, production and marketing canbe categorized as medium category. Factors that affect the self-sufficiency in thecapital aspect was age. The self-sufficiency in the aspects of production wasinfluenced by the source of information, and the self-sufficiency in the marketingaspect was influenced by the partnership relationship. Based on the results of theresearch, it is recommended to increase the extension to increase knowledge offarmers related to vegetable agribusiness.
