1 URBAN AGRICULTURE AS AN ALTERNATIVE POLICY FOR MANAGEMENT OF DESAKOTA REGIONS by: Dr. agr. Didit Okta Pribadi

2 INTRODUCTION Urban sprawl in Asia leads to development of megacities having > 10 million inhabitants and encompassing cities, town, villages, and rural areas (UN-Habitat and UNESCAP, 2015). Urban sprawl occurred in the dense agricultural zones and created a specific feature called desakota where urban and rural systems are intermingled to form a seemingly chaotic land use pattern (McGee, 1991; Yokohari et al., 2000; Moench & Gyawali, 2008) While some scholars regarded desakota is a temporary features during urbanization, emerging food security, poverty, and environmental issues have enhanced the role of desakota in supporting urban resilience and sustainability (McGee, 2010; Rustiadi, et al., 2015). Still, management of desakota regions is a big issue

3 Urban agriculture offers a promising concept as it emphasizes the integration of agriculture into urban socioeconomic and ecological systems (Mougeot, 2000) Multifunctionality and connectivity to the urban system become a key to manage peri-urban agriculture (PUA) (Zasada, 2011) However, the application of the concept is hindered by a lack of understanding of: (1) farming types in peri-urban areas and their particular response to rapid urban expansion (2) the potential ecological and social benefits derived from these farming types (3) effective policies for integrating agriculture into urban development and for enhancing their social and ecological benefits

4 To close the knowledge gap, this study has objectives as follows: 1) to investigate the character of urban sprawl and its impact on the dynamics of PUA. 2) To analyze the relationships between PUA types and socioeconomic issues as well as environmental issues. 3) To asses the potential of PUA contributing to the urban sustainability through multifunctional farming. 4) To draw conclusions towards development of policies which effectively support multifunctional PUA

5 Macro Trend of Urbanization PUA Response to Urbanization PUA management based on farming types adaptation to urbanization ANALYTICAL FRAMEWORK Meso Socioeconomic functions of PUA Ecological functions of PUA Types, areas, and different functions of PUA that should be preserved Micro PUA Farm Characteristics PUA Farm Adaptation Transformation of rural-traditional farming into multifunctional and sustainable PUA Policies for PUA management Farm types adaptation to urbanization Functions and services of farmland at the landscape level Farming capacities to develop multifunctional practices

6 MATERIAL AND METHODS STUDY AREA 6,256 km2 with a population million in sub-districts and 1,495 villages in 2011 The northern part alluvial zone, while the southern part mountainous area

7 MICRO MESO MACRO METHODS DATA METHODS OUTCOME Series of satellite images Series of socioeconomic data Field observation of agricultural land use Land use change analysis Multivariate statistic of socioeconomic panel data Spatial mapping and clustering of farming types The dynamics of PUA and different farming types during rapid urbanization in JMA Socioeconomic data by village Socioeconomic data by sub district Land use maps, soil types, rainfall, topography, farmland management Correspondence Analysis Geographically Weighted Regression (GWR) Peak Flow Model Soil Erosion Model PUA zoning analysis The link of PUA in a particular area with the urban socioeconomic and ecological system Questionnaire based interviews with farmers Descriptive Analysis Benefit-Cost Ratio Analysis Correspondence analysis Farm s capacity to adapt to urbanization and develop multifunctional practices

8 RESULTS AND DISCUSSION MACRO STUDY Main Findings Continuation of urban sprawl caused farmland conversion and fragmentation in the peri-urban region Built Up Ratio Log. (1993) Log. (2003) Log. (2008) y = 0,2051ln(x) - 0,1951 R² = 0,5785 y = 0,2143ln(x) - 0,1528 R² = 0,5166 y = 0,1923ln(x) - 0,0852 R² = 0, Density (Population Number/Ha) Type of neighborhood Only built up / non built up area Mixed built up and non built up area Percent of Neighborhood Number

13 MESO STUDY (I) main findings PUA had a close economic link with low and middle class residential areas and small-medium scale urban economic activities. Dimension 2; Eigenvalue: (13.35% of Inertia) Villa Hotel Farmer Household Stall Household Food Stall Small Scale Industry Restaurant Mini-market Non Permanent Traditional Market Permanent Traditional Market Dimension 1; Eigenvalue: (15.43% of Inertia) Increasing poverty were followed by increasing numbers of farmers in the southeast and decreasing numbers of farmer in the north of JMA. North capital intensive farming Southeast low capital farming Poor Almost Poor

14 Self Employed Free Workers Non-Paid Workers PUA had a close economic link with low and middle class residential areas and small-medium scale urban economic activities. PUA had a capability to support food security policy only in the surroundings of Jakarta, east, and northeast of JMA dominated by staple food production farming Income Food Prices Farmers

16 SOIL EROSION USLE MODEL RUNOFF PEAK FLOW MODEL MESO STUDY (II)- main findings Expansion of PUA in the catchment areas led to increased runoff and soil erosion

17 MAPS OF ZONES THAT INFLUENCE RUNOFF AND SOIL EROSION 74%, 81%, 58% of PUA land located in critical zones (2,3,4) in Kali Bekasi, Ciliwung, and Cisadane respectively, dominated by dryland horticulture and mixed garden. Only a minor proportion of PUA land (9-10%) should be reforested Soil and water conservation application in PUA farming is important

19 MICRO STUDY Main Findings Table 1. Farmers Characteristics in the Ciliwung Upstream Area (Source: Author s survey) Characteristics Farmers No. in percent (%) Education No school Primary education (elementary school) Secondary education (highschool) University Age Productive age (15-64) Above productive age (>64) Area of origin Local Immigrant Status Full-time farmer type Full-time farmer type Part-time Agricultural type Horticulture Paddy Other food crops Land access type Own property Rent Mortgaged land Production-sharing Property guard Land encroachment Farmers in the CSA are not well educated, not all are local people, most of them are full-time farmers, and still in the working age.

20 Paddy Field Horticulture Horticulture emerged as large-scale farming further from the settlements, whereas paddy fields showed subsistence farming in the smaller and fragmented land near the settlements. Both were developed on land not owned by farmers.

21 Full time, younger, and higher capital farmers tend to develop horticulture, whereas part time, older, and lower capital farmers tend to develop paddy field. Both have lack of strong multifunctionality (i.e. strong socioeconomic and environmental value) due to declining productivity for horticulture and low benefit for paddy fields, thus farming sustainability will be threatened - unsustained Farmers capacity to apply strong multifunctionality should be supported and it is determined by their individual capacity (age, work time, capital), intrinsic motives (profit or subsistence), and land tenure situation.

22 High Profit Secure Multifunctional agriculture Farmer Capacity Farmer Motive Insecure Access on Land Lack of environmental conservation Increasing skill, capital, time Diversifying Non-food product Non-marketable public benefit Securing Minimize risk in dynamics peri-urban setting Low Subsistence Lack of generating income and jobs, but providing food for the poor

24 CONCLUSION At the macro level, PUA should not be neglected and needs to be managed as it keeps persisting as one of the major land use type that could support urban resilience, especially at the time of crisis. At the meso level, PUA zones which have different functions across the landscapes should be developed by considering farming types, size, distribution, and their adaptation to urbanization. At the micro level, multifunctional farming should be applied to maintain farming business. Developing multifunctional farming is not only farmers responsibility, but also other stakeholders e.g. government and urban society to develop non-food marketable product and services (e.g. agrotourism, agro-education, etc.) and non marketable public benefits (e.c. enhancing food security, supporting peri-urban economy, increasing environmnetal quality).
