Abstract

Changes in national parks (NP) governance include 1) change in NP management policy which was originally precedence for protection and preservation, now includes real economy for the community, 2) implementation process of the change at field level. This paper discusses the governance change in Gunung Halimun Salak National Park (TNGHS) and its impacts on resource users. Change in governance could take place if the interactive process that occurred between the Head of the National Park, field officers and the community included: (1) Clear and simple policy guidance from the Head of NP on the policy implementation of the new governance be given to field officers, (2) develop relationship between field officers and local community through active interaction. Shift in the implementation technique of NP governance for protection and preservation from "restrictions and provision of sanctions" to "participatory conservation" to achieve the goal of NP resources utilization for the community. The analysis showed that change in NP governance was achieved through the approach of participatory conservation processes, learning and increasing confidence that comes naturally among the field officers and local communities and conservation practices by local communities. Keywords: change in NP governance, restrictions and provisions of sanctions, participatory conservation, learning, increasing confidence

Abstract

Forest Reference Emission Level (FREL) is one of four required elements for developing countries in  implementing REDD+ activities, and serves  as a benchmark in assessing  REDD+ performance. This study assessed the emission level from mangrove deforestation in Mahakam Delta - East Kalimantan, aiming to enhance the baseline for subnational FREL document. Over the observation period of 1980-2001, conversion of mangrove forest into aquaculture ponds has resulted in a massive mangrove loss, with an estimation of  3,183 hectare/year, or equivalent to the release of 0.46 Tg CO2e/year. If soil pool was also  included in the calculation, mangrove deforestation in Mahakam Delta between 1980 and 2001 emitted 2.9 TgCO2e/year. The CO2 emission from aquaculture ponds may couple with mangrove deforestation, which released 52 Gg CO2 /year from the pond floor. After 2001, the rate of mangrove deforestation decreased, allowing mangrove forests to recover with the expansion rate of 1,546 hectare/ year during 2001-2011 or equivalent to the carbon sequestration or removal of 0.67-4.7 TgCO2e/year. The results of the study suggest the way to improve the existing FREL by raising the importance of mangrove as “blue” carbon, with reference of the 2013 IPCC Guideline: Wetland Supplement.

Abstract

Soil salinity is one major environmental constraint on rice production, especially in coastal areas. The development of salt-tolerant genotypes is considered to be the most effective breeding strategy to overcome the constraint. This study aims to induce somatic embryos formation of East Kalimantan local rice cultivars and to obtain tolerant somatic embryos under saline condition via in vitro selection. Four commonly cultivated local rice cultivars, namely Buyung, Siam, Ketalun Tawar and Serai Gunung, were used in this study. The somatic embryos were produced using three different plant growth regulator (PGR) compositions. The salinity tolerance level of somatic embryos was induced by in vitro selection in salt toxicity medium containing 0 mM; 50 mM; 100 mM; 150 mM; 200 mM NaCl. The best medium for somatic embryogenesis contains 1 mg/l 2,4-D + 0.5 m/l  BAP, resulting the highest percentage of cream and white non-compact callus on the tested cultivars. More than 70% of the somatic embryos were tolerant against salinity (NaCl 200 mM). However, only somatic embryos derived from Serai Gunung could regenerate into normal plantlets.
