PERENCANAN PENGGUNAAN LAHAN BERKELANJUTAN MK. LANDUSE PLANNING & PENGEMBANGAN WILAYAH Smno.pdip.ppsfpub.2013
2 KENDALA-KENDALA PENGELOLAAN LAHAN BERKELANJUTAN 1. Terbatasnya ketersediaan lahan pertanian 2. Degradasi Lahan 3. Loss of Agricultural Land to Urbanization 4. Water Shortages 5. Biophysical constraints 6. Socio-economic constraints 7. Perubahan kebijakan publik
KONSEP PENGELOLAAN LAHAN BERKELANJUTAN Pillars (UNCED, 1993) 1. Productivity-Maintain or enhance production/services. 2. Security-Reduce the level of production risk. 3. Protection-Protect the potential or natural resources and prevent degradation of soil and water quality. 4. Viable- Secara ekonomi layak. 5. Acceptability – Secara sosial dapat diterima masyarakat
5 PERTANIAN RAMAH LINGKUNGAN characterized by two distinct categories of farming systems that share symbiotic relationships with each other. – Estate farms on flat to gentle undulating lands – Subsistence farms on the more marginal lands.
6 Karakteristik Usahatani Komersial 1. Commercial and export oriented 2. Mono cropping system on the same plot of land for many years 3. Rely heavily on subsistence farm labour to carry out farming operations 4. Utilizes conventional intensive farming technology. 5. Influence by the political climate (internal and external)
CONCERNS Degradation: 1. Declining yields 2. Influence of soil borne and other diseases 3. Declining soil fertility (shortening or elimination fallow periods) 4. Pollution of ground water 5. Soil salinity 6. Globalization
KARAKTERISTIK PERTANIAN SUBSISTEN 1. Complex farming systems geared mainly at the domestic market 2. Soil erosion and watershed degradation 3. Relies on commercial farms and other off- farm activities for employment to supplement farm income 4. Multiple cropping system which varies according to season.
PETANI SUBSISTEN 1. Business approach type farmers 2. Commercial/subsistence type farmers 3. Serious farmers without the means 4. Farmers with resources which are not utilized 5. Farmers by default 6. Pandangan Hidup Petani (P. Meikle, 1998)
INDIKATOR KEBERLANJUTAN Since the concept of sustainable development cannot be defined, indicators should be developed to determine levels and duration of sustainability (Zinc and Farshad, 1995). ESDI indicator for Agriculture, land and food Arable and permanent crop land area
Database Iklim 1. All countries have a network of meteorological stations, to observe and document climate and weather conditions. 2. In areas of difficult access, these stations may be wide apart with a limited number of recording years 3. Time gaps in recording 4. Incompleteness in the range of attributes needed. ISU-ISU & TANTANGAN
Tanah & Bentang Lahan Classification criteria and naming of soils differ among countries, making correlations between classifications and countries difficult ISU-ISU & TANTANGAN
Database Sumberdaya Air 1. Analysis of data from meteorological stations 2. Repeated measurements of stream flows 3. Assessment of ground water reserves through borehole analysis 4. Amount and types of actual uses being made of the water resources. 5. Some countries may not have the equipment or resources to take these measurements on an on-going basis. 6. Cost of taking some of these measurements may be expensive. ISU-ISU & TANTANGAN
14 Database Tutupan Lahan & Biodiversitas Geo-ref Geo-refe renced information on floral and faunal diversity is scarce Areas of known or inferred archeological value or reflecting typical past land use systems need to be mapped ISU-ISU & TANTANGAN
Lahan, Tanaman dan Sistem Produksi 1.Land use information is usually consolidated at district level rather than being fully georeferenced. 2.Lack of practical, simple and widely accepted method of describing land uses and production systems is a serious constraint 3.Each land use type should be assessed on its inherent sustainability, on the basis of a set of sustainable indicators ISU-ISU & TANTANGAN
Lahan, Tanaman dan Sistem Produksi 1.Basic information on the environmental requirements of new cultivars and non-traditional crops is not widely available or may not be available for the conditions in some SIDS. 2.Existing databases are limited with respect to coverage and classes 3.Little management information included in maps ISU-ISU & TANTANGAN
17 1.Economy of inputs and outputs is liable to strong variability 2.Biophysical databases may have a useable lifetime of 20 - 30 years 3.Economic and social databases will normally have to be revised every 5 - 10 years. 4.Limitation in data availability and data quality at all scales, especially those that require substantial ground truthing 5.Lack of METADATA and protocols for data collection. ISU-ISU & TANTANGAN
