Sustainable Management of Land Resources

Land use is one of the macro parameters that affects water quality in a watershed. The Cimanuk watershed which is dominated by agricultural land use and settlements has encountered a decline in water quality. There are eight parameters including pH, TDS, TSS, Nitrate, Phosphate, Sulphate, BOD, and COD analyzed to evaluate water quality utilizing the Pollution Index (IP) method. This research has provided a clear understanding of the status of water quality in the Cimanuk watershed based on six monitoring points carried out at the start of the 2018 rainy season. Overall, the IP values obtained ranged from 2.05 to 5.96 with the lightly polluted category at points A, B, C, D, and E, while for point F it was in the moderately polluted category. The key parameters that have the most influence on water quality pollution are Nitrate, Phosphate, Sulphate from fertilization activities in agricultural land, while runoff from settlements contribute to increasing parameters of BOD and COD. These results can be beneficial for sustainable management of water and land resources in the Cimanuk watershed.

The Impact

One of the major environmental issues currently facing New Zealand is that of the sustainability of pastoral farming on North Island hill country. To be sustainable, a system must be resource conserving, environmentally compatible, socially supportive and commer-cially competitive. The Resource Management Act defines sustainable management as managing the use, development and protection of natural and physical resources in a way, or at a rate, which enables people and community to meet their needs without unduly compromising the ability of future generations to meet their needs. Evidence shows that at present this is not so for some hill country, for reasons of on-site land degradation and soil loss, and off-site sediment loading. Socioeconomic sustainability is also in doubt through deterioration in rural infrastructure and social services and steadily decreasing average returns for produce. In the long term there is no conflict between environmental and economic sustainability. The major conflict arises in the short term when the environmental needs of the community can conflict severely with the economic survival of the individual land holder. Adoption of sustainable management will require a much greater understanding of the dynamic interaction between land resources and land use practices and improved matching of land uses with inherent soil and climatic properties. A quantitative understanding of the relationship between biophysical stability of our land resources and their productive capability is required. This paper attempts to: (i) examine how biophysical indicators could be used to quantify the impact of current land use on the productive capability of our hill land resource, and in so doing identify several critical issues facing hill country farmers, and (ii) discuss some of the possible solutions to what we see are currently unsustainable farming practices. It is our contention that the adoption of sustainable management practices will ensure the long-term viability of this sector of the pasture industry and not, as many suggest, its demise.

Close Relationship

The significance of the security of electrical energy, water, and food resources in the future, which are inextricably connected, has led to increasing attention to this important issue in studies. This is an issue inattention to which can have irreparable consequences in the future. One of the sectors where electrical energy, water, and food are very closely associated is agriculture. Undoubtedly, the ability to properly manage electrical energy, hydropower, and food resources that have many uncertainties brings about the development of agriculture on the one hand and the optimal allocation of electrical energy, water, and land resources on the other. Thus, while reaching the highest economic profit, the greenhouse gas emissions reach the minimum possible value too. In this study, via robust optimization and by precisely considering the existing uncertainties, a model was developed for the optimal allocation of electrical energy, water, and land resources for a region in the north of China. In addition to acknowledging the close relationship between electrical energy, water, and food sources, the results show the method’s effectiveness for sustainable management in agriculture.

Depth Interviews

The relationship between Fulani herdsmen and farmers has in recent years become hot-tempered motivated by competitive control of land resources, particularly in central and north-east Nigeria. In Taraba State, the ongoing nomadic migration pattern from the Sahel in quest of pastures has led to violent confrontation between Fulani herdsmen and farming indigenous natives. Using a descriptive approach consisting of documented evidence, in-depth interviews, and focus group discussions, the analysis revealed that conflicts between Fulani herdsmen and indigenous native farmers have culminated in population displacement and destruction of life and property in numerous rural enclaves in Taraba State. Despite the consequences of the conflicts, the Taraba State government was unable to act proactively because of the centralization of command over Nigerian security agencies. Accordingly, the study suggests decentralization of security agencies in Nigeria, especially the police, as the way forward for effective security governance in Nigeria.
