Water is a vital renewable resource that is increasingly stressed by multiple and competing demands from people, industry, and agriculture. When water becomes unavailable or unusable, life itself cannot be sustained. Changes in supply and demand for water are driven by population growth, climate change, and our energy and land use choices. Poverty frequently precludes the ability of many people to respond and adapt to water insecurity. In this essay, we discuss the effects of these drivers on the diminution of rivers, aquifers, glaciers, and the severe pollution that renders some water resources unusable. While technologies for water reuse, desalination, aquifer replenishment, and better water pricing are important solutions, the recognition of water as a profoundly threatened resource and as a basic human right is essential for providing sustainable water for future generations.

For countries in Southeast Asia that mainly rely on surface water as their water resource, changes in weather patterns and hydrological systems due to climate change will cause severely decreased water resource availability. Warm weather triggers more water use and exacerbates the extraction of water resources, which will change the operation patterns of water usage and increase demand, resulting in water scarcity. The occurrence of prolonged drought upsets the balance between water supply and demand, significantly increasing the vulnerability of regions to damaging impacts. The objectives of this study are to identify trends and determine the impacts of extreme drought events on water levels for the major important water dams in the northern part of Borneo, and to assess the risk of water insecurity for the dams. In this context, remote sensing images are used to determine the degree of risk of water insecurity in the regions. Statistical methods are used in the analysis of daily water levels and rainfall data. The findings show that water levels in dams on the North and Northeast Coasts of Borneo are greatly affected by the extreme drought climate caused by the Northeast Monsoon, with mild to the high risk recorded in terms of water insecurity, with only two of the water dams being water-secure. This study shows how climate change has affected water availability throughout the regions.

The concept of sustainable agriculture involves meeting society?s current food and material needs without compromising the ability of future generations to do the same, and is a core theme of the green deal. Sustainability is closely linked to resilience, i.e. the capacity of food systems over time to provide sufficient, adequate, and accessible food to all, in the face of various and even unforeseen challenges. Food systems cannot expect to be resilient to challenges such as climate change and COVID-19 if they are not sustainable. Historically, solutions to produce more food sustainably focussed on bringing more land into agriculture, exploiting new or underutilised resources, and adopting new technologies. However, it is now recognised that we need to do more with less, and use what we have wisely and with the best scientific and ecological investments, especially in Europe. Pressures on land use from a growing population to build houses, transport, and infrastructure, as well as protecting habitats for recreation and biodiversity, mean that simply finding more agricultural land is not an option.

The number of clean water needed will always increase when the number of the population still shows growth. It must have the same level from the supply and demand or the supply of clean water has higher than the demand for clean water. Some cities in Indonesia have problems with the fulfilment of clean water. Factors from climate change, behaviour, and management can affect the conditions of clean water resources. The development of technologies and science makes the reuse of the water process can be done for another resource of clean water fulfilment. Rainwater harvesting, membrane bioreactors, reverse osmosis, and filtration systems are some kind of processing systems for the water mechanism for the fulfilment of clean water. Sustainable clean water resources and supply is one of the indicators of sustainable development goals. This research was conducted to see how is the potential of water reuse for the fulfilment of clean water in Indonesia by using several systems or processing that have been installed and used. The control and evaluation is the best key to make sure the clean water resources still in the best condition and water reuse is one of the plan to support fulfilment of clean water.

Climate change (CC) and its impacts on the socio-economy and the development of communities has become an issue causing very special concern. The rise in global temperatures, in sea levels, extreme weather phenomena, and salinization have occurred more and more and have directly influenced the livelihoods of rural households in the Red River Delta – one of the two regions projected to suffer strongly from climate change in Vietnam. For farming households in this region, the major and traditional livelihoods are based on main production materials as agricultural land, or aquacultural water surface Changes in the land use of rural households in the Red River Delta during recent times was influenced strongly by the Renovation policy in agriculture as well as the process of industrialization and modernization in the country. Climate change over the past 5 years (2005-2011) has started influencing household land use with the concrete manifestations being the reduction of the area cultivated and the changing of the purpose of land use.

A warm welcome to our "World of Difference" to all delegates attending this conference - we hope your stay is enjoyable and that you will leave Central Otago with an enhanced appreciation of the diversity of land use and the resilient and growing economic potential that this region has to offer. Without regional wellbeing the national economy will struggle to grow, something Central Government finally seems to be realising, and the Central Otago District Council Long Term Plan 2012-2022 (LTP) signals the importance of establishing a productive economy for the local community which will aid in the economic growth of the district and seeks to create a thriving economy that will be attractive to business and residents alike. Two key principles that underpin the LTP are sustainability and affordability, with the definition of sustainability being "… development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

Penelitian ini menguji teori Marx yang mengatakan bahwa dalam proses kapitalisasi, petani lahan kecil akan tergusur oleh petani lahan besar. Penelitian ini menggunakan pendekatan kualitatif dengan metode Participatory Action Research (PAR). Menggunakan teknik observasi partisipasi di lapangan, studi ini melakukan wawancara mendalam terhadap petani. Analisis data yang digunakan bersifat induktif. Penelitian ini menghasilkan kesimpulan, bahwa teori Marx tidak terjadi di malar Aman. Adapun penyebab menurunnya pertanian disebabkan menurunnya unsur hara tanah, mahalnya biaya produksi, alih fungsi lahan dan perubahan cuaca. Sedangkan strategi petani lahan kecil untuk mempertahankan kehidupan yaitu melakukan pola tanam tumpang sari, melakukan pekerjaan tambahan, dan mengatur keuangan.This study examines Marx's theory which says that in the process of capitalization, small land farmers will be displaced by large land farmers. This study uses a qualitative approach with the method of Participatory Action Research (PAR). Using the techniques of participatory observation in the field, the study conducted in-depth interviews on farmers. Analysis of the data used is inductive. This study led to the conclusion that Marx's theory does not happen in Aman malar. The cause of the decline of agriculture due to declining soil nutrients, the high cost of production, land use and climate change. While the strategies of small land farmers to sustain life is to do the planting patterns of intercropping, do extra work, and manage finances.
