Agricultural production is one of the most weather sensitive human activities that depend on daily atmospheric conditions. This review attempts to describe the meteorological data for crop requirements, some techniques of climate prediction and its use for crop simulations. Despite the rapid progress achieved in forecasting technology lately, further works are necessary for the real application. The amount and distribution of the rainfall in the coming season is necessary for planning crop cultivation particularly when climate anomaly arises. In agriculture the efforts to bridge the gap, climate forecasting results are the main input in crop simulation, especially for water and agro-climate management and cropping calendar.

Development problems of agriculture on border area require handling which more comprehensive and sustainable. Up to now, research results indicate that efforts has been done in handling various problems in agricultural sector, but still partial and is not be able to overcome complex problems. Therefore to overcome various development problems of agriculture on the border area need to be done in holisticaly, covers all aspect i.e. social, economics, ecology, and institution. Sebatik Island is one of state border area between Indonesia and Malaysia, located in Nunukan District, East Kalimantan Province. Up to now, cocoa is still the priority commodity, but its productivity is relatively low. Based on potency and constraint of land resources in Sebatik Island, sustainable recommendations to increase land productivity of cocoa i.e. (1) land and water conservation management, (2) using organic matter, (3) proportional fertilization, (4) using mulch, (5) integrated crop management, (6) integrated crop-livestock system, and (7) improvement of capacity of farmers institution

As a seasonal crop, rice production is highly depend on the carrying capacity of the climate, that the changing climate requires the adaptive capacity of the farmers. On the other hand, climate change is still a new and complex issue for most people which is followed by differences in response to its impact. This research tries to describe the relationship between communication variables and adaptive capacity to climate change of rice farmers. The survey method is applied in lowland, midland, and upland agroecosystem zones affected by climate change which are represented by 32 rice farmers each. The result shows that there is a very strong relation between climate change communication variables of the farmers and their capacity in adapting to the climate change. Therefore, the diversity of sources of climate change information of the farmers and the frequency of its use, and the exposure to climate change information and convergence of climate change communication of the farmers need to be improved.

The lake Tondano in North Sulawesi Province, has very important role, namely as the source of domestic water use for Manado town, electric power generator, fisheries, and tourism. It has been issued to serious siltation process over the tolerable Iimit due to soil erosion, so that the water quantity and quality are worried to be decrease. The objective of the research is to study the possibility occuring of lake siltation caused by soil erosion, by analyzing the hydrological and soil characteristics data from the Tondano catchment. The hydrological data analysis includes the river discharge and sediment discharge entering the lake, lake depth, and lake water balance. The soil data analysis consists of chemical and physical soil properties, soil infiltration rate, and erosion hazard of the catchment predicted by universal soil loss equation (USLE) method. The results indicate that the water lake level fluctuation and the outlet discharge depend on the amount of rainfall. The discharge of sediment suspension entering the Jake was 7,540 tons per year compared to the lake volume as much as 680 millions m3, the lake would be full-filled by the sediments in thousands of years. The measured deepest lake depth at present is about 22 m, and during the last century, the lake was decrease as much as 6 m. The infiltration rate of main soils varies from moderate to very rapid (22- 71 cm/hr), and are still higher than the maximum absolute rainfallintensity, so that overland flow occurs very little. The amount of soil loss by erosion indicates that 94% of the catchment area is lower than the maximum tolerable limits (< 12 t/ha/yr). This research has proved that the hydrological and soil condition of the Tondano catchment have not yet been serious degradation caused by erosion, so that the accelerated siltation due to erosion process was not occur in the lake catchment and its surrounding.
