Goal to achieving Sustainable Agriculture

Sustainability implies the capacity to endure, diversify and maintain efficiency for an indefinite period of time, in relation to the three core elements – environment, society and economy. The latest published Environment for Europeans magazine, in March 2017, tackles the concept of a sustainable future in the long-term. At the regional level, sustainability needs to be considered as a global vision, as highlighted in the 2030 Agenda for Sustainable Development, adopted by world leaders in the 70^th UN General Assembly in 2015. The environment has to be seen hand-in-hand with themes related to agriculture, education, health, social protection, climate change, etc… Despite the policy level, additional actions and stakeholder engagement are necessary for the full implementation of policies.

Sustainable agriculture is part of the focus of the second goal of the 2030 Agenda, which can only be tackled through the sustainable management of natural resources. The EU Commission’s communication also identifies that “Agriculture plays a substantial role in the 2030 Agenda and in any sustainable future as it is intrinsically linked to issues such as jobs, food, air, climate change, water, soil and biodiversity.” [1] Agriculture is sustainable when it becomes an integrated system of production lasting in the long term, whilst satisfying needs related to human consumption, economic viability, protection of natural resources and adaptation to climate change.

One way by which agriculture may be sustainable is if it is based on small-scale food producers, who are also locals. Sustainable food production with increased productivity may also be possible if agricultural practices are resilient. The EU’s “Sustainable agriculture for the future we want” specifies that the EU is making its utmost for a greener agriculture.[2] Sustainable management is also considered in the proposed core objectives for the EU’s CAP 2014-2020.[3] One of the identified challenges for which the CAP reform was made, is related to the importance of enhancing the sustainable management of natural resources including water, air, soil and biodiversity, and to consider the increasing pressure brought by ongoing climatic changes.

In the local scenario, sustainable agriculture is important for several environmental benefits – ranging from protection of water quality and soil functionality, preservation of biodiversity and ecosystem services, reduction in greenhouse gas emissions and reduction of pollution:

• Soil functionality – the threat of soil erosion in the Maltese Islands associated with reduced soil quality and low levels of organic matter, needs to be reduced by securing soil functionality. The degradation of soil can be prevented through maintenance of soil structure and organic matter. Soil has a function as a carbon sink, meaning that it has an important role in mitigating climate change. Farming practices have to be appropriate and directed at utmost soil management. The repair of dilapidated rubble walls and the construction of new rubble walls is a good practice to maintain soil management of the Maltese Islands with various other environmental benefits.

• Water management – Water resources are already threatened in the Maltese Islands. whilst the practices of installing systems of drip irrigation are necessary if water is to be effectively and efficiently utilised. Over abstraction of groundwater and the reduced use of surface runoff for irrigation, coupled with the effects of drier seasons are major threats to the agricultural sector. A good practice of irrigation, which should be promoted is the use of drip irrigation systems that use water effectively and efficiently.

• Biodiversity protection – The importance of local species is crucial for the maintenance of genetic diversity. The planting of local trees and sequestering carbon in soil will mitigate against the negative consequence of greenhouse gases, whilst contributing to other positive environmental benefits related to enhanced biodiversity. Biodiversity and agriculture are also linked, since biodiversity e.g. soil organisms and plants contribute to enhance soil fertility. In turn, agriculture is able to create habitats, enhancing biological diversity. 

Hence, the conservation of natural resources means effective soil management and water conservation, and this may be seen in relation to adapting to climate change. The fragmentation of land and land abandonment has continued to threaten agricultural land. Promoting agricultural production and land consolidation will deliver valuable ecosystem services including the retention of water and nutrients, soil conservation and carbon storage.

An important consideration is that rural development consists of three roles, related to production, wardens of the environment and conservation of biodiversity, and finally the embellishment of the countryside for visual purposes.
